Pluralistic: AI "journalists" prove that media bosses don't give a shit (11 Mar 2026)


Today's links


A cutaway of a rocky underground, with a cylindrical brick cistern. Trapped in the prison is a 16th century drudge seated before a wheel on which rest a series of books that rotate along with the wheel.

AI "journalists" prove that media bosses don't give a shit (permalink)

Ed Zitron's a fantastic journalist, capable of turning a close read of AI companies' balance-sheets into an incandescent, exquisitely informed, eye-wateringly profane rant:

https://www.wheresyoured.at/the-ai-bubble-is-an-information-war/

That's "Ed, the financial sleuth." But Ed has another persona, one we don't get nearly enough of, which I delight in: "Ed the stunt journalist." For example, in 2024, Ed bought Amazon's bestselling laptop, "a $238 Acer Aspire 1 with a four-year-old Celeron N4500 Processor, 4GB of DDR4 RAM, and 128GB of slow eMMC storage" and wrote about the experience of using the internet with this popular, terrible machine:

https://www.wheresyoured.at/never-forgive-them/

It sucked, of course, but it sucked in a way that the median tech-informed web user has never experienced. Not only was this machine dramatically underpowered, but its defaults were set to accept all manner of CPU-consuming, screen-filling ad garbage and bloatware. If you or I had this machine, we would immediately hunt down all those settings and nuke them from orbit, but the kind of person who buys a $238 Acer Aspire from Amazon is unlikely to know how to do any of that and will suffer through it every day, forever.

Normally the "digital divide" refers to access to technology, but as access becomes less and less of an issue, the real divide is between people who know how to defend themselves from the cruel indifference of technology designers and people who are helpless before their enshittificatory gambits.

Zitron's stunt stuck with me because it's so simple and so apt. Every tech designer should be forced to use a stock configuration Acer Aspire 1 for a minimum of three hours/day, just as every aviation CEO should be required to fly basic coach at least one out of three flights (and one of two long-haul flights).

To that, I will add: every news executive should be forced to consume the news in a stock browser with no adblock, no accessibility plugins, no Reader View, none of the add-ons that make reading the web bearable:

https://pluralistic.net/2026/03/07/reader-mode/#personal-disenshittification

But in all honesty, I fear this would not make much of a difference, because I suspect that the people who oversee the design of modern news sites don't care about the news at all. They don't read the news, they don't consume the news. They hate the news. They view the news as a necessary evil within a wider gambit to deploy adware, malware, pop-ups, and auto-play video.

Rawdogging a Yahoo News article means fighting through a forest of pop-ups, pop-unders, autoplay video, interrupters, consent screens, modal dialogs, modeless dialogs – a blizzard of news-obscuring crapware that oozes contempt for the material it befogs. Irrespective of the words and icons displayed in these DOM objects, they all carry the same message: "The news on this page does not matter."

The owners of news services view the news as a necessary evil. They aren't a news organization: they are an annoying pop-up and cookie-setting factory with an inconvenient, vestigial news entity attached to it. News exists on sufferance, and if it was possible to do away with it altogether, the owners would.

That turns out to be the defining characteristic of work that is turned over to AI. Think of the rapid replacement of customer service call centers with AI. Long before companies shifted their customer service to AI chatbots, they shifted the work to overseas call centers where workers were prohibited from diverging from a script that made it all but impossible to resolve your problems:

https://pluralistic.net/2025/08/06/unmerchantable-substitute-goods/#customer-disservice

These companies didn't want to do customer service in the first place, so they sent the work to India. Then, once it became possible to replace Indian call center workers who weren't allowed to solve your problems with chatbots that couldn't resolve your problems, they fired the Indian call center workers and replaced them with chatbots. Ironically, many of these chatbots turn out to be call center workers pretending to be chatbots (as the Indian tech joke goes, "AI stands for 'Absent Indians'"):

https://pluralistic.net/2024/01/29/pay-no-attention/#to-the-little-man-behind-the-curtain

"We used an AI to do this" is increasingly a way of saying, "We didn't want to do this in the first place and we don't care if it's done well." That's why DOGE replaced the call center reps at US Customs and Immigration with a chatbot that tells you to read a PDF and then disconnects the call:

https://pluralistic.net/2026/02/06/doge-ball/#n-600

The Trump administration doesn't want to hear from immigrants who are trying to file their bewildering paperwork correctly. Incorrect immigration paperwork is a feature, not a bug, since it can be refined into a pretext to kidnap someone, imprison them in a gulag long enough to line the pockets of a Beltway Bandit with a no-bid contract to operate an onshore black site, and then deport them to a country they have no connection with, generating a fat payout for another Beltway Bandit with the no-bid contract to fly kidnapped migrants to distant hellholes.

If the purpose of a customer service department is to tell people to go fuck themselves, then a chatbot is obviously the most efficient way of delivering the service. It's not just that a chatbot charges less to tell people to go fuck themselves than a human being – the chatbot itself means "go fuck yourself." A chatbot is basically a "go fuck yourself" emoji. Perhaps this is why every AI icon looks like a butthole:

https://velvetshark.com/ai-company-logos-that-look-like-buttholes

So it's no surprise that media bosses are so enthusiastic about replacing writers with chatbots. They hate the news and want it to go away. Outsourcing the writing to AI is just another way of devaluing it, adjacent to the existing enshittification that sees the news buried in popups, autoplays, consent dialogs, interrupters and the eleventy-million horrors that a stock browser with default settings will shove into your eyeballs on behalf of any webpage that demands them:

https://pluralistic.net/2024/05/07/treacherous-computing/#rewilding-the-internet

Remember that summer reading list that Hearst distributed to newspapers around the country, which turned out to be stuffed with "hallucinated" titles? At first, the internet delighted in dunking on Marco Buscaglia, the writer whose byline the list ran under. But as 404 Media's Jason Koebler unearthed, Buscaglia had been set up to fail, tasked with writing most of a 64-page insert that would have normally been the work of dozens of writers, editors and fact checkers, all on his own:

https://www.404media.co/chicago-sun-times-prints-ai-generated-summer-reading-list-with-books-that-dont-exist/

When Hearst hires one freelancer to do the work of dozens, they are saying, "We do not give a shit about the quality of this work." It is literally impossible for any writer to produce something good under those conditions. The purpose of Hearst's syndicated summer guide was to bulk out the newspapers that had been stripmined by their corporate owners, slimmed down to a handful of pages that are mostly ads and wire-service copy. The mere fact that this supplement was handed to a single freelancer blares "Go fuck yourself" long before you clap eyes on the actual words printed on the pages.

The capital class is in the grips of a bizarre form of AI psychosis: the fantasy of a world without people, where any fool idea that pops into a boss's head can be turned into a product without having to negotiate its creation with skilled workers who might point out that your idea is pretty fucking stupid:

https://pluralistic.net/2026/01/05/fisher-price-steering-wheel/#billionaire-solipsism

For these AI boosters, the point isn't to create an AI that can do the work as well as a person – it's to condition the world to accept the lower-quality work that will come from a chatbot. Rather than reading a summer reading list of actual books, perhaps you could be satisfied with a summer reading list of hallucinated books that are at least statistically probable book-shaped imaginaries?

The bosses dreaming up use-cases for AI start from a posture of profound and proud ignorance of how workers who do useful things operate. They ask themselves, "If I was a ______, how would I do the job?" and then they ask an AI to do that, and declare the job done. They produce utility-shaped statistical artifacts, not utilities.

Take Grammarly, a company that offers statistical inferences about likely errors in your text. Grammar checkers aren't a terrible idea on their face, and I've heard from many people who struggle to express themselves in writing (either because of their communications style, or because they don't speak English as a first language) for whom apps like Grammarly are useful.

But Grammarly has just rolled out an AI tool that is so obviously contemptuous of writing that they might as well have called it "Go fuck yourself, by Grammarly." The new product is called "Expert Review," and it promises to give you writing advice "inspired" by writers whose writing they have ingested. I am one of these virtual "writing teachers" you can pay Grammarly for:

https://www.theverge.com/ai-artificial-intelligence/890921/grammarly-ai-expert-reviews

This is not how writing advice works. When I teach the Clarion Science Fiction and Fantasy Writers' workshop, my job isn't to train the students to produce work that is strongly statistically correlated with the sentence structure and word choices in my own writing. My job – the job of any writing teacher – is to try and understand the student's writing style and artistic intent, and to provide advice for developing that style to express that intent.

What Grammarly is offering isn't writing advice, it's stylometry, a computational linguistics technique for evaluating the likelihood that two candidate texts were written by the same person. Stylometry is a very cool discipline (as is adversarial stylometry, a set of techniques to obscure the authorship of a text):

https://en.wikipedia.org/wiki/Stylometry

But stylometry has nothing to do with teaching someone how to write. Even if you want to write a pastiche in the style of some writer you admire (or want to send up), word choices and sentence structure are only incidental to capturing that writer's style. To reduce "style" to "stylometry" is to commit the cardinal sin of technical analysis: namely, incinerating all the squishy qualitative aspects that can't be readily fed into a model and doing math on the resulting dubious quantitative residue:

https://locusmag.com/feature/cory-doctorow-qualia/

If you wanted to teach a chatbot to teach writing like a writer, you would – at a minimum – have to train that chatbot on the instruction that writer gives, not the material that writer has published. Nor can you infer how a writer would speak to a student by producing a statistical model of the finished work that writer has published. "Published work" has only an incidental relationship to "pedagogical communication."

Critics of Grammarly are mostly focused on the effrontery of using writers' names without their permission. But I'm not bothered by that, honestly. So long as no one is being tricked into thinking that I endorsed a product or service, you don't need my permission to say that I inspired it (even if I think it's shit).

What I find absolutely offensive about Grammarly is not that they took my name in vain, but rather, that they reduced the complex, important business of teaching writing to a statistical exercise in nudging your work into a word frequency distribution that hews closely to the average of some writer's published corpus. This is Grammarly's fraud: not telling people that they're being "taught by Cory Doctorow," but rather, telling people that they are being "taught" anything.

Reducing "teaching writing" to "statistical comparisons with another writer's published work" is another way of saying "go fuck yourself" – not to the writers whose identities that Grammarly has hijacked, but to the customers they are tricking into using this terrible, substandard, damaging product.

Preying on aspiring writers is a grift as old as the publishing industry. The world is full of dirtbag "story doctors," vanity presses, fake literary agents and other flimflam artists who exploit people's natural desire to be understood to steal from them:

https://writerbeware.blog/

Grammarly is yet another company for whom "AI" is just a way to lower quality in the hopes of lowering expectations. For Grammarly, helping writers with their prose is an irritating adjunct to the company's main business of separating marks from their money.

In business theory, the perfect firm is one that charges infinity for its products and pays zero for its inputs (you know, "scholarly publishing"). For bosses, AI is a way to shift their firm towards this ideal.

In this regard, AI is connected to the long tradition of capitalist innovation, in which new production efficiencies are used to increase quantity at the expense of quality. This has been true since the Luddite uprising, in which skilled technical workers who cared deeply about the textiles they produced using complex machines railed against a new kind of machine that produced manifestly lower quality fabric in much higher volumes:

https://pluralistic.net/2023/09/26/enochs-hammer/#thats-fronkonsteen

It's not hard to find credible, skilled people who have stories about using AI to make their work better. Elsewhere, I've called these people "centaurs" – human beings who are assisted by machines. These people are embracing the socialist mode of automation: they are using automation to improve quality, not quantity.

Whenever you hear a skilled practitioner talk about how they are able to hand off a time-consuming, low-value, low-judgment task to a model so they can focus on the part that means the most to them, you are talking to a centaur. Of course, it's possible for skilled practitioners to produce bad work – some of my favorite writers have published some very bad books indeed – but that isn't a function of automation, that's just human fallibility.

A reverse centaur (a person conscripted to act as a peripheral to a machine) is trapped by the capitalist mode of automation: quantity over quality. Machines work faster and longer than humans, and the faster and harder a human can be made to work, the closer the firm can come to the ideal of paying zero for its inputs.

A reverse centaur works for a machine that is set to run at the absolute limit of its human peripheral's capability and endurance. A reverse centaur is expected to produce with the mechanical regularity of a machine, catching every mistake the machine makes. A reverse centaur is the machine's accountability sink and moral crumple-zone:

https://estsjournal.org/index.php/ests/article/view/260

AI is a normal technology, just another set of automation tools that have some uses for some users. The thing that makes AI signify "go fuck yourself" isn't some intrinsic factor of large language models or transformers. It's the capitalist mode of automation, increasing quantity at the expense of quality. Automation doesn't have to be a way to reduce expectations in the hopes of selling worse things for more money – but without some form of external constraint (unions, regulation, competition), that is inevitably how companies will wield any automation, including and especially AI.

The Binance crypto exchange has just filed a defamation lawsuit against the Wall Street Journal over its article reporting that Binance's own compliance investigators had found $1 billion in transfers to Iran-backed terror groups, and then were fired.

The article, and related investigations by the New York Times and Fortune, were cited in an inquiry over the alleged sanctions evasion by Senator Blumenthal, and a request by Sen. Van Hollen and others for an investigation by the Treasury and Justice Departments. Today the WSJ reported that the DOJ had opened such an investigation.

Binance spends much of the filing complaining that news outlets like the WSJ do not give them enough credit for how hard they're trying. I'm not sure bragging about stopping $131M in illicit transfers quite lands when the whole point of this article is that you allegedly allowed 10x that.

Pluralistic: Ad-tech is fascist tech (10 Mar 2026)


Today's links


Times Square, lit up by night. Every ad sprouts a giant CCTV bubble. A green smoke crawls over the landscape.

Ad-tech is fascist tech (permalink)

A core tenet of the enshittification hypothesis is that all the terrible stuff we're subjected to in our digital lives today is the result of foreseeable (and foreseen) policy choices, which created the enshittogenic policy environment in which the worst people's worst ideas make the most money:

https://pluralistic.net/2025/09/10/say-their-names/#object-permanence

Take commercial surveillance. Google didn't have to switch from content-based ads (which chose ads based on your search terms and the contents of webpages) to surveillance-based ads (which used dossiers on your searches, emails, purchases and physical movements to target ads to you, personally). The content-based ads made Google billions, but the company made a gamble that surveillance-based ads would make them more money.

That gamble had two parts: the first was that advertisers would pay more for surveillance ads. This is the part we all focus on – the collusion between people who want to sell us stuff and companies willing to spy on us to help them do it.

But the other half of the bet is far more important: namely, whether spying on us would cost Google anything. Would they face fines? Would users collect massive civil judgments over these privacy violations? Would Google face criminal charges? These are the critical questions, because even if advertisers are willing to pay a premium for surveillance ads, it only makes sense to collect that premium if the excess profit it represents is larger than the anticipated penalties for committing surveillance crimes.

What's more, advertisers and Google execs all work for their shareholders, in a psychotic "market system" in which the myth of "fiduciary duty" is said to require companies to hurt us right up to the point where the harms they inflict on the world cost them more than the additional profits those harms deliver:

https://pluralistic.net/2024/09/18/falsifiability/#figleaves-not-rubrics

But the policymakers who ultimately determine whether the fines, judgments and criminal penalties outstrip the profits from spying – they work for us. They draw their paychecks from the public purse in exchange for safeguarding our interests, and they have manifestly failed at this.

Why did Google decide to start spying on us? For the same reason your dog licks its balls: because they could. The last consumer privacy law to make it out of the US Congress was a 1988 bill that banned video-store clerks from disclosing your VHS rentals:

https://pluralistic.net/2025/10/31/losing-the-crypto-wars/#surveillance-monopolism

And yes, the EU did pass a comprehensive consumer privacy law, but then abdicated any duty to enforce the GDPR, because US Big Tech companies pretend to be Irish, and Ireland is a crime-haven that lets the tax-evaders who maintain the fiction of a Dublin HQ break any EU law they find inconvenient:

https://pluralistic.net/2025/12/01/erin-go-blagged/#big-tech-omerta

The most important question for Google wasn't "Will advertisers pay more for surveillance targeting?" It was "Will lawmakers clobber us for spying on the whole internet?" And the answer to that second question was a resounding no.

Why did policymakers fail us? It's not much of a mystery, I'm afraid. Policymakers failed us because cops and spies hate privacy laws and lobby like hell against them. Cops and spies love commercial surveillance, because the private sector's massive surveillance dossiers are an off-the-books trove of warrantless surveillance data that the government can't legally collect. What's more, even if the spying was legal, buying private sector surveillance data is much cheaper than creating a public sector surveillance apparatus to collect the same info:

https://pluralistic.net/2023/08/16/the-second-best-time-is-now/#the-point-of-a-system-is-what-it-does

The harms of mass commercial surveillance were never hard to foresee. 20 years ago, Radar magazine commissioned a story from me about "the day Google turned evil," and I turned in "Scroogled," which was widely shared and reprinted:

https://web.archive.org/web/20070920193501/https://radaronline.com/from-the-magazine/2007/09/google_fiction_evil_dangerous_surveillance_control_1.php/

Radar is long gone, though it's back in the news now, thanks to the revelation that it was financed via Jeffrey Epstein as part of his plan to both control and loot magazines and newspapers:

https://www.reddit.com/r/Epstein/comments/142bufo/radar_magazine_lines_up_financing_published_2004/

But the premise of "Scroogled" lives on. 20 years ago, I wrote a story in which the bloated, paranoid, lawless DHS raided ad-tech databases of behavioral data in order to target people for secret arrests, extraordinary rendition, and torture.

It took a minute, but today, the DHS is paying data-brokers and ad-tech giants like Google for commercial surveillance data that it is using to feed the systems that automatically decide who will be kidnapped, rendered and tortured by ICE:

https://www.theregister.com/2026/01/27/ice_data_advertising_tech_firms/

I want to be clear here: I'm not claiming any prescience – quite the reverse in fact. My point is that it just wasn't very hard to see what would happen if we let the surveillance advertising industry run wild. Our lawmakers were warned. They did nothing. They exposed us to this risk, which was both foreseeable and foreseen.

Nor did the ICE/ad-tech alliance drop out of the sky. The fascist mobilization of ad-tech data for a racist pogrom is the latest installment in a series of extremely visible, worsening weaponizations of commercial surveillance. Just last year, I testified before Biden's CFPB at hearings on a rule to kill the data-broker industry, where we heard from the Pentagon about ad-tech targeting of American military personnel with gambling problems with location-based ads that reached them in their barracks:

https://pluralistic.net/2025/02/20/privacy-first-second-third/#malvertising

Biden's CFPB passed the data broker-killing rule, but Trump and DOGE nuked it before it went into effect. Trump officials didn't offer any rationale for this, despite the fact that the testimony in that hearing included a rep from the AARP who described how data brokers let advertisers target seniors with signs of dementia (a core Trump voter bloc). I don't know for sure, but I have a sneaking suspicion that the Stephen Miller wing of the Trump coalition wanted data brokers intact so that they could use them to round up and imprison/torture/murder/enslave non-white people and Trump's political enemies.

Despite this eminently foreseeable outcome of the ad-tech industry, many perfectly nice people who made extremely nice salaries working in ad-tech are rather alarmed by this turn of events:

https://quoteinvestigator.com/2017/11/30/salary/

On Adxchanger.com, ad-tech exec David Nyurenberg writes, "The Privacy ‘Zealots’ Were Right: Ad Tech’s Infrastructure Was Always A Risk":

https://www.adexchanger.com/data-driven-thinking/the-privacy-zealots-were-right-ad-techs-infrastructure-was-always-a-risk/

Nyurenberg opens with a very important point – not only is ad-tech dangerous, it's also just not very good at selling stuff. The claims for the efficacy of surveillance advertising are grossly overblown, and used to bilk advertisers out of high premiums for a defective product:

https://truthset.com/the-state-of-data-accuracy-form/

There's another point that Nyurenberg doesn't make, but which is every bit as important: many of ad-tech's fiercest critics have abetted ad-tech's rise by engaging in "criti-hype" (repeating hype claims as criticism):

https://peoples-things.ghost.io/youre-doing-it-wrong-notes-on-criticism-and-technology-hype/

The "surveillance capitalism" critics who repeated tech's self-serving mumbo-jumbo about "hacking our dopamine loops" helped ad-tech cast itself in the role of mind-controlling evil sorcerers, which greatly benefited these self-styled Cyber-Rasputins when they pitched their ads to credulous advertisers:

https://pluralistic.net/HowToDestroySurveillanceCapitalism

Nyurenberg points to European privacy activists like Johnny Ryan and Max Schrems, who have chased American surveillance advertising companies out of the Irish courts and into other EU territories and even Europe's federal court, pointing out that these two (and many others!) have long warned the world about the way that this data would be weaponized. Johnny Ryan famously called ad-tech's "realtime bidding" system, "the largest data breach ever recorded":

https://committees.parliament.uk/writtenevidence/453/html/

Ryan is referring to the fact that you don't even have to buy an ad to amass vast databases of surveillance data about internet users. When you land on a webpage, every one of the little boxes where an ad will eventually show up gets its own high-speed auction in which your private data is dangled before anyone with an ad-tech account, who gets to bid on the right to shove an ad into your eyeballs. The losers of that auction are supposed to delete all your private data that they get to see through this process, but obviously they do not.

And Max Schrems has hollered from the mountaintops for years about the inevitability of authoritarian governments helping themselves to ad-tech data in order to suppress dissent and terrorize their political opposition:

https://www.bipc.com/european-high-court-finds-eu-us-privacy-shield-invalid

Nyurenberg says his friends in ad-tech are really upset that these (eminently foreseeable) outcomes have come to pass, but (he says), ad-tech bosses claim they have no choice but to collaborate with the Trump regime. After all, we've seen what Trump does to companies that don't agree to help him commit crimes:

https://apnews.com/article/anthropic-trump-pentagon-hegseth-ai-104c6c39306f1adeea3b637d2c1c601b

Nyurenberg closes by upbraiding his ad-tech peers for refusing to engage with their critics during the decades in which it would have been possible to do something to prevent this outcome. Ad-tech insiders dismissed privacy activists as unrealistic extremists who wanted to end advertising itself and accused ad-tech execs of wanting to create a repressive state system of surveillance. In reality, critics were just pointing out the entirely foreseeable repressive state surveillance that ad-tech would end up enabling.

I'm quite pleased to see Nyurenberg calling for a reckoning among his colleagues, but I think there's plenty of blame to spread around. Sure, the ad-tech industry built this fascist dragnet – but a series of governments around the world let them do it. There was nothing inevitable about mass commercial surveillance. It doesn't even work very well! Mass commercial surveillance is the public-private partnership from hell, where cops and spies shielded ad-tech companies from regulation in exchange for those ad-tech companies selling cops and spies unlimited access to their databases.

Our policymakers are supposed to work for us. They failed us. Don't let anyone tell you that the greed and depravity of ad-tech are the sole causes of Trump's use of ad-tech to decide who to kidnap and send to a Salvadoran slave-labor camp. Policymakers should have known. They did know. They had every chance to stop this. They did not.

Examples for the tcpdump and dig man pages

Hello! My big takeaway from last month’s musings about man pages was that examples in man pages are really great, so I worked on adding (or improving) examples to two of my favourite tools’ man pages.

Here they are:

the goal: include the most basic examples

The goal here was really just to give the absolute most basic examples of how to use the tool, for people who use tcpdump or dig infrequently (or have never used it before!) and don’t remember how it works.

So far saying “hey, I want to write an examples section for beginners and infrequent users of this tools” has been working really well. It’s easy to explain, I think it makes sense from everything I’ve heard from users about what they want from a man page, and maintainers seem to find it compelling.

Thanks to Denis Ovsienko, Guy Harris, Ondřej Surý, and everyone else who reviewed the docs changes, it was a good experience and left me motivated to do a little more work on man pages.

why improve the man pages?

I’m interested in working on tools’ official documentation right now because:

  • Man pages can actually have close to 100% accurate information! Going through a review process to make sure that the information is actually true has a lot of value.
  • Even with basic questions “what are the most commonly used tcpdump flags”, often maintainers are aware of useful features that I’m not! For example I learned by working on these tcpdump examples that if you’re saving packets to a file with tcpdump -w out.pcap, it’s useful to pass -v to print a live summary of how many packets have been captured so far. That’s really useful, I didn’t know it, and I don’t think I ever would have noticed it on my own.

It’s kind of a weird place for me to be because honestly I always kind of assume documentation is going to be hard to read, and I usually just skip it and read a blog post or Stack Overflow comment or ask a friend instead. But right now I’m feeling optimistic, like maybe the documentation doesn’t have to be bad? Maybe it could be just as good as reading a really great blog post, but with the benefit of also being actually correct? I’ve been using the Django documentation recently, and it’s really good! We’ll see.

on avoiding writing the man page language

The tcpdump project tool’s man page is written in the roff language, which is kind of hard to use and that I really did not feel like learning it.

I handled this by writing a very basic markdown-to-roff script to convert Markdown to roff, using similar conventions to what the man page was already using. I could maybe have just used pandoc, but the output pandoc produced seemed pretty different, so I thought it might be better to write my own script instead. Who knows.

I did think it was cool to be able to just use an existing Markdown library’s ability to parse the Markdown AST and then implement my own code-emitting methods to format things in a way that seemed to make sense in this context.

man pages are complicated

I went on a whole rabbit hole learning about the history of roff, how it’s evolved since the 70s, and who’s working on it today, inspired by learning about the mandoc project that BSD systems (and some Linux systems, and I think Mac OS) use for formatting man pages. I won’t say more about that today though, maybe another time.

In general it seems like there’s a technical and cultural divide in how documentation works on BSD and on Linux that I still haven’t really understood, but I have been feeling curious about what’s going on in the BSD world.

The comments section is here.

Pluralistic: Billionaires are a danger to themselves and (especially) us (09 Mar 2026)


Today's links


A king on a sumptuous, much elaborated throne; in one hand he holds a sceptre of office, in the other, the leashes for two fierce stone dogs that guard the throne. The king's head has been replaced with a character who was used as the basis for MAD Magazine's Alfred E Neumann. The new head sports a conical dunce cap. Behind the king is a large group of 1960s business men, seated and standing, in conservative suits. The background is the view from the 80th floor of World Trade Center 3. The floor has been carpeted in sumptuous tabriz from the Ottoman court.

Billionaires are a danger to themselves and (especially) us (permalink)

Even if rich people were no more likely to believe stupid shit than you or me, it would still be a problem. After all, I believe in my share of stupid shit (and if you think that none of the shit you believe in is stupid, then I'm afraid we've just identified at least one kind of stupid shit you believe in).

The problem isn't whether rich people believe stupid shit; it's the fact that when a rich person believes something stupid, that belief can turn into torment for dozens, thousands, or millions of people.

Here's a historical example that I think about a lot. In 1928, Henry Ford got worried about the rubber supply chain. All the world's rubber came from plantations in countries that he had limited leverage over and he was worried that these countries could kneecap his operation by cutting off the supply. So Ford decided he would start cultivating rubber in the Brazilian jungles, judging that Brazil's politicians were biddable, bribeable or bludgeonable and thus not a risk.

Ford took over a large area of old-growth jungle in Brazil and decreed that a town be built there. But not just any town: Ford decreed that the town of Fordlandia would be a replica of Dearborn, the company town he controlled in Michigan. Now, leaving aside the colonialism and other ethical considerations, there are plenty of practical reasons not to replicate Dearborn, MI on the banks of the Rio Tapajós.

For one thing, Brazil is in the southern hemisphere, and Dearborn is in the northern hemisphere. The prefab houses that Ford ordered for Fordlandia had windows optimized for southern exposure, which is the normal way of designing a dwelling in the northern hemisphere. In the southern hemisphere, you try and put your windows on the other side of the building.

Ford's architects told him this, and proposed having the factory flip the houses' orientation. But Ford was adamant: he'd had a vision for a replica of his beloved Dearborn plunked down smack in the middle of the Amazon jungle, and by God, that was what he would get:

https://memex.craphound.com/2010/06/02/fordlandia-novelistic-history-of-henry-fords-doomed-midwestern-town-in-the-amazon-jungle/

Fordlandia was a catastrophe for so many reasons, and the windows are just a little footnote, but it's a detail that really stuck with me because it's just so stupid. Ford was a vicious antisemite, a bigot, a union-buster and an all-round piece of shit, but also, he believed that his opinions trumped the axial tilt of the planet Earth.

In other words, Henry Ford wasn't merely evil – he was also periodically as thick as pigshit. Ford's cherished stupidities didn't just affect him, they also meant that a whole city full of people in the Amazon had windows facing the wrong direction. Like I said, I sometimes believe stupid things, but those stupid things aren't consequential the way that rich people's cherished stupidities are.

This would be bad enough if rich people were no more prone to stupid beliefs than the rest of us, but it's actually worse than that. When I believe something stupid, it tends to get me in trouble, which means that (at least some of the time), I get to learn from my mistakes. But if you're a rich person, you can surround yourself with people who will tell you that you are right even when you are so wrong, with the result that you get progressively more wrong, until you literally kill yourself:

https://www.scientificamerican.com/article/alternative-medicine-extend-abbreviate-steve-jobs-life/

A rich person could surround themselves with people who tell them that they're being stupid, but in practice, this almost never happens. After all, the prime advantage to accumulating as much money as possible is freedom from having to listen to other people. The richer you are, the fewer people there are who can thwart your will. Get rich enough and you can be found guilty of 34 felonies and still become President of the United States of America.

But wait, it gets even worse! Hurting other people is often a great way to get even more rich. So the richer you get, the more insulated you are from consequences for hurting other people, and the more you hurt other people, the richer you get.

What a world! The people whose wrong beliefs have the widest blast-radius and inflict the most collateral damage also have the fewest sources of external discipline that help them improve their beliefs, and often, that collateral damage is a feature, not a bug.

Billionaires are a danger to themselves and (especially) to the rest of us. They are wronger than the median person, and the consequences of their wrongness are exponentially worse than the consequences of the median person's mistake.

This has been on my mind lately because of a very local phenomenon.

I live around the corner from Burbank airport, a great little regional airport on the edge of Hollywood. It was never brought up to code, so the gates are really close together, which means the planes park really close together, and there's no room for jetways, so they park right up against the terminal. The ground crews wheel staircase/ramps to both the front and back of the plane. That means that you can walk the entire length of the terminal in about five minutes, and boarding and debarking takes less than half the time of any other airport. Sure, if one of those planes ever catches fire, every other plane is gonna go boom, and everyone in the terminal is toast, but my sofa-to-gate time is like 15 minutes.

Best of all, Burbank is a Southwest hub. When we moved here a decade ago, this was great. Southwest, after all, has free bag-check, open seating, a great app, friendly crews, and a generous policy for canceling or changing reservations.

If you fly in the US, you know what's coming next. In 2024, a hedge fund called Elliott Investment Management acquired an 11% stake in SWA, forced a boardroom coup that saw it replace five of the company's six directors, and then instituted a top to bottom change in airline policies. The company eliminated literally everything that Southwest fliers loved about the airline, from the free bags to the open seating:

https://www.reddit.com/r/SouthwestAirlines/comments/1ji79zt/elliott_management_is_dismantling_everything/

The airline went from being the least enshittified airline in America to the most. Southwest is now worse than Spirit airlines – no, really. Southwest doesn't just merely charge for seat selection, but if you refuse to pay for seat selection, they preferentially place you in a middle seat even on a half-empty flight, as a way of pressuring you to pay the sky-high junk fee for seat selection:

https://www.reddit.com/r/SouthwestAirlines/comments/1rd2g0k/ngl_thought_yall_were_joking/

Obviously, passengers who are given middle seats (and the passengers around them, who paid for window or aisle seats) don't like this, so they try to change seats. So SWA now makes its flight attendants order passengers not to switch seats, and they've resorted to making up nonsense about "weight balancing":

https://www.reddit.com/r/SouthwestAirlines/comments/1roz1bg/you_can_change_to_an_empty_seatbut_only_until_we/

Even without junk fees, Southwest's fares are now higher than their rivals. I'm flying to San Francisco tomorrow to host EFF executive director Cindy Cohn's book launch at City Lights:

https://citylights.com/events/cindy-cohn-launch-party-for-privacys-defender/

Normally, I would have just booked a SWA flight from Burbank to SFO or Oakland (which gets less fog and is more reliable). But the SWA fare – even without junk fees – was higher than a United ticket out of the same airport, even including a checked bag, seat selection, etc. Southwest is genuinely worse than Spirit now: not only does it have worse policies (forcing occupancy of middle seats!), and more frustrated, angrier flight crew (flight attendants are palpably sick of arguing with passengers), but SWA is now more expensive than United!

All of this is the fault of one billionaire: Elliott Investment Management CEO Paul Singer, one of America's most guillotineable plutes. This one guy personally enshittified Southwest Airlines, along with many other businesses in America and abroad. Because of this one guy, millions of people are made miserable every single day. Singer flogged off his shares and made a tidy profit. He's long gone. But SWA will never recover, and every day until its collapse, millions of passengers and flight attendants will have a shitty day because of this one guy:

https://www.wfaa.com/article/money/business/southwest-airlines-activist-investor-elliott-lower-ownership-stake/287-470b5131-ef1a-4648-a8ec-4cc017f7914c

Even if Paul Singer were no more prone to ethical missteps than you or me, the fact that he is morbidly wealthy means that his ethical blind spots leave behind a trail of wreckage that rivals a comet. And of course, being as rich as Paul Singer inflicts a lasting neurological injury that makes you incapable of understanding how wrong you are, which means that Paul Singer is doubly dangerous.

Billionaires aren't just a danger when they're trying to make money, either. One of the arguments in favor of billionaires is that sometimes, the "good" billionaires take up charitable causes. But even here, billionaires can cause sweeping harm. Take Bill Gates, whose charitable projects include waging war on the public education system, seeking to replace public schools with charter schools.

Gates has no background in education, but he spent millions on this project. He is one of the main reasons that poor communities around the country have been pressured to shutter their public schools and replace them with weakly regulated, extractive charters:

https://apnews.com/article/92dc914dd97c487a9b9aa4b006909a8c

This was a catastrophe. A single billionaire dilettante's cherished stupidity wrecked the educational chances of a generation of kids:

https://dissidentvoice.org/2026/03/free-market-charter-schools-wreak-havoc-in-michigan/

Gates was a prep-school kid, so it's weird for him to have forceful views about a public education system he never experienced. In reality, it's not so much that Gates has forceful views about schools – rather, he has forceful views about teachers' unions, which he wishes to see abolished. Gates is one of America's most vicious union-busters:

https://teamster.org/2019/10/teamsters-union-and-allies-protest-bill-gates-and-cambridge-union-society/

Gates's ideology permeates all of his charitable work. We all know about Gates's work on public health, but less well known is the role that Gates has played in blocking poor countries from exercising their rights under the WTO to override drug patents in times of emergency. In the 2000s, the Gates Foundation blocked South Africa from procuring the anti-retroviral AIDS drugs it was entitled to under the WTO's TRIPS agreement. The Gates Foundation blocked the Access to Medicines WIPO treaty, which would have vastly expanded the Global South's ability to manufacture life-saving drugs. And during the acute phase of the covid pandemic, Gates personally intervened to kill the WHO Covid-19 Technology Access Pool and to get Oxford to renege on its promise to make an open-source vaccine:

https://pluralistic.net/2021/04/13/public-interest-pharma/#gates-foundation

It's not that Gates is insincere in his desire to improve public health outcomes – it's that his desire to improve public health conflicts with his extreme ideology of maximum intellectual property regimes. Gates simply opposes open science and compulsory licenses on scientific patents, even when that kills millions of people (as it did in South Africa). Gates's morbid wealth magnifies his cherished stupidities into weapons of mass destruction.

Gates is back in the news these days because of his membership in the Epstein class. Epstein is the poster child for the ways that wealth is a force-multiplier for bad ideas. We can't separate Epstein's sexual predation from his wealth. Epstein spun elaborate junk-science theories to justify raping children, becoming mired in that most rich-guy coded of quagmires, eugenics:

https://www.statnews.com/2026/02/24/epstein-cell-line-george-church-harvard-personal-genome-project/

Epstein openly discussed his plans to seed the planet with his DNA, reportedly telling one scientist that he planned to fill his ranch with young trafficked girls and to keep 20 of them pregnant with his children at all times:

https://www.nytimes.com/2019/07/31/business/jeffrey-epstein-eugenics.html

We still don't know where Epstein's wealth came from, but we know that he was a central node in a network of vast riches, much of which he directed to his weird scientific projects. That network also protected him from consequences for his prolific child-rape project, which had more than 1,000 survivors.

In embracing eugenics junk science, Epstein was ahead of the curve. Today, eugenics is all the rage, reviving an idea that went out of fashion shortly after the Fordlandia era. After all, Henry Ford didn't just build a private city where his word was law – he also bought up media companies to promote his ideas of racial superiority:

https://en.wikipedia.org/wiki/The_Dearborn_Independent

Despite being too cringe to make it onto Epstein island, Elon Musk is the standard bearer for the dangers of billionaireism:

https://people.com/emails-reveal-that-elon-musk-asked-jeffrey-epstein-about-visiting-his-island-11896842

Like Henry Ford, he craves company towns where his word is law:

https://www.texasmonthly.com/news-politics/inside-starbase-spacex-elon-musk-company-town/

Like Ford, he buys up media companies and then uses them to push his batshit ideas about racial superiority:

https://www.motherjones.com/politics/2025/01/eugenics-isnt-dead-its-thriving-in-tech/

Like Paul Singer, he is a master enshittifier who never met a junk fee he didn't fall in love with:

https://edition.cnn.com/2022/11/01/tech/musk-twitter-verification-price

And like Epstein, he wants to seed the human race with his babies, and has built a secret compound in the desert he plans to fill with women he has impregnated:

https://www.realtor.com/news/celebrity-real-estate/elon-musk-compound-austin-children/

Billionaires and their lickspittles will tell you that all of this is wrong: the market selects "capital allocators" by executing a vast, distributed computer program whose logic gates are every producer and consumer in The Economy (TM), and whose data are trillions of otherwise uncomputable buy and sell decisions.

This is a tautology: the argument goes that only good people are made rich, and therefore all the rich people are good. If rich people had as many cherished stupidities as I claim, The Economy (TM) would relieve them of their wealth, and thus their power to allocate capital, and thus their potential to hurt people by being wrong, which means that they must be right.

This is the stupidest (and most destructive) of all of billionaireism's cherished stupidities: that we live in a meritocracy, which means that whatever the richest people want must be right. It's a modern update to the doctrine of divine providence, which held that we can discern god's favor through wealth. The more god loves you, the richer he makes you.

This can't be true, because every single economic cataclysm in the history of the world was the fault of rich people. Rich people gave us the 19th century's bank panics. They gave us the South Seas bubble. They gave us the Great Depression, and the S&L Crisis, and the Great Financial Crisis. They invented greedflation and created the cost of living crisis. Today, they are teeing up an AI crash that will make 2008 look like the best day of your life:

https://pluralistic.net/2025/12/05/pop-that-bubble/#u-washington

The old left aphorism has it that "every billionaire is a policy failure." That's true, but it's incomplete. Every billionaire is a machine for producing policy failures at scale.

Just like the crypto space, a lot of senators are scared to stick their neck out even though action is being demanded of us on this issue.

Pluralistic: The web is bearable with RSS (07 Mar 2026)


Today's links


An anatomical drawing of a cross-section of a man's head. The eyeball has been replaced by an RSS logo. To the left of the face is a 'code waterfall' effect as seen in the credit sequences of the Wachowskis' 'Matrix' movie. To the right are clouds of grey roiling clouds, infiltrating the brain as well.

The web is bearable with RSS (permalink)

Never let them tell you that enshittification was a mystery. Enshittification isn't downstream of the "iron laws of economics" or an unrealistic demand by "consumers" to get stuff for free.

Enshittification comes from specific policy choices, made by named individuals, that had the foreseeable and foreseen result of making the web worse:

https://pluralistic.net/2025/10/07/take-it-easy/#but-take-it

Like, there was once a time when an ever-increasing proportion of web users kept tabs on what was going on with RSS. RSS is a simple, powerful way for websites to publish "feeds" of their articles, and for readers to subscribe to those feeds and get notified when something new was posted, and even read that new material right there in your RSS reader tab or app.

RSS is simple and versatile. It's the backbone of podcasts (though Apple and Spotify have done their best to kill it, along with public broadcasters like the BBC, all of whom want you to switch to proprietary apps that spy on you and control you). It's how many automated processes communicate with one another, untouched by human hands. But above all, it's a way to find out when something new has been published on the web.

RSS's liftoff was driven by Google, who released a great RSS reader called "Google Reader" in 2007. Reader was free and reliable, and other RSS readers struggled to compete with it, with the effect that most of us just ended up using Google's product, which made it even harder to launch a competitor.

But in 2013, Google quietly knifed Reader. I've always found the timing suspicious: it came right in the middle of Google's desperate scramble to become Facebook, by means of a product called Google Plus (G+). Famously, Google product managers' bonuses depended on how much G+ engagement they drove, with the effect that every Google product suddenly sprouted G+ buttons that either did something stupid, or something that confusingly duplicated existing functionality (like commenting on Youtube videos).

Google treated G+ as an existential priority, and for good reason. Google was running out of growth potential, having comprehensively conquered Search, and having repeatedly demonstrated that Search was a one-off success, with nearly every other made-in-Google product dying off. What successes Google could claim were far more modest, like Gmail, Google's Hotmail clone. Google augmented its growth by buying other peoples' companies (Blogger, YouTube, Maps, ad-tech, Docs, Android, etc), but its internal initiatives were turkeys.

Eventually, Wall Street was going to conclude that Google had reached the end of its growth period, and Google's shares would fall to a fraction of their value, with a price-to-earnings ratio commensurate with a "mature" company.

Google needed a new growth story, and "Google will conquer Facebook's market" was a pretty good one. After all, investors didn't have to speculate about whether Facebook was profitable, they could just look at Facebook's income statements, which Google proposed to transfer to its own balance sheet. The G+ full-court press was as much a narrative strategy as a business strategy: by tying product managers' bonuses to a metric that demonstrated G+'s rise, Google could convince Wall Street that they had a lot of growth on their horizon.

Of course, tying individual executives' bonuses to making a number go up has a predictably perverse outcome. As Goodhart's law has it, "Any metric becomes a target, and then ceases to be a useful metric." As soon as key decision-makers' personal net worth depending on making the G+ number go up, they crammed G+ everywhere and started to sneak in ways to trigger unintentional G+ sessions. This still happens today – think of how often you accidentally invoke an unbanishable AI feature while using Google's products (and products from rival giant, moribund companies relying on an AI narrative to convince investors that they will continue to grow):

https://pluralistic.net/2025/05/02/kpis-off/#principal-agentic-ai-problem

Like I said, Google Reader died at the peak of Google's scramble to make the G+ number go up. I have a sneaking suspicion that someone at Google realized that Reader's core functionality (helping users discover, share and discuss interesting new web pages) was exactly the kind of thing Google wanted us to use G+ for, and so they killed Reader in a bid to drive us to the stalled-out service they'd bet the company on.

If Google killed Reader in a bid to push users to discover and consume web pages using a proprietary social media service, they succeeded. Unfortunately, the social media service they pushed users into was Facebook – and G+ died shortly thereafter.

For more than a decade, RSS has lain dormant. Many, many websites still emit RSS feeds. It's a default behavior for WordPress sites, for Ghost and Substack sites, for Tumblr and Medium, for Bluesky and Mastodon. You can follow edits to Wikipedia pages by RSS, and also updates to parcels that have been shipped to you through major couriers. Web builders like Jason Kottke continue to surface RSS feeds for elaborate, delightful blogrolls:

https://kottke.org/rolodex/

There are many good RSS readers. I've been paying for Newsblur since 2011, and consider the $36 I send them every year to be a very good investment:

https://newsblur.com/

But RSS continues to be a power user-coded niche, despite the fact that RSS readers are really easy to set up and – crucially – make using the web much easier. Last week, Caroline Crampton (co-editor of The Browser) wrote about her experiences using RSS:

https://www.carolinecrampton.com/the-view-from-rss/

As Crampton points out, much of the web (including some of the cruftiest, most enshittified websites) publish full-text RSS feeds, meaning that you can read their articles right there in your RSS reader, with no ads, no popups, no nag-screens asking you to sign up for a newsletter, verify your age, or submit to their terms of service.

It's almost impossible to overstate how superior RSS is to the median web page. Imagine if the newsletters you followed were rendered with black, clear type on a plain white background (rather than the sadistically infinitesimal, greyed-out type that designers favor thanks to the unkillable urban legend that black type on a white screen causes eye-strain). Imagine reading the web without popups, without ads, without nag screens. Imagine reading the web without interruptors or "keep reading" links.

Now, not every website publishes a fulltext feed. Often, you will just get a teaser, and if you want to read the whole article, you have to click through. I have a few tips for making other websites – even ones like Wired and The Intercept – as easy to read as an RSS reader, at least for Firefox users.

Firefox has a built-in "Reader View" that re-renders the contents of a web-page as black type on a white background. Firefox does some kind of mysterious calculation to determine whether a page can be displayed in Reader View, but you can override this with the Activate Reader View, which adds a Reader View toggle for every page:

https://addons.mozilla.org/en-US/firefox/addon/activate-reader-view/

Lots of websites (like The Guardian) want you to login before you can read them, and even if you pay to subscribe to them, these sites often want you to re-login every time you visit them (especially if you're running a full suite of privacy blockers). You can skip this whole process by simply toggling Reader View as soon as you get the login pop up. On some websites (like The Verge and Wired), you'll only see the first couple paragraphs of the article in Reader View. But if you then hit reload, the whole article loads.

Activate Reader View puts a Reader View toggle on every page, but clicking that toggle sometimes throws up an error message, when the page is so cursed that Firefox can't figure out what part of it is the article. When this happens, you're stuck reading the page in the site's own default (and usually terrible) view. As you scroll down the page, you will often hit pop-ups that try to get you to sign up for a mailing list, agree to terms of service, or do something else you don't want to do. Rather than hunting for the button to close these pop-ups (or agree to objectionable terms of service), you can install "Kill Sticky," a bookmarklet that reaches into the page's layout files and deletes any element that isn't designed to scroll with the rest of the text:

https://github.com/t-mart/kill-sticky

Other websites (like Slashdot and Core77) load computer-destroying Javascript (often as part of an anti-adblock strategy). For these, I use the "Javascript Toggle On and Off" plugin, which lets you create a blacklist of websites that aren't allowed to run any scripts:

https://addons.mozilla.org/en-US/firefox/addon/javascript-toggler/

Some websites (like Yahoo) load so much crap that they defeat all of these countermeasures. For these websites, I use the "Element Blocker" plug-in, which lets you delete parts of the web-page, either for a single session, or permanently:

https://addons.mozilla.org/en-US/firefox/addon/element-blocker/

It's ridiculous that websites put so many barriers up to a pleasant reading experience. A slow-moving avalanche of enshittogenic phenomena got us here. There's corporate enshittification, like Google/Meta's monopolization of ads and Meta/Twitter's crushing of the open web. There's regulatory enshittification, like the EU's failure crack down on companies the pretend that forcing you to click an endless stream of "cookie consent" popups is the same as complying with the GDPR.

Those are real problems, but they don't have to be your problem, at least when you want to read the web. A couple years ago, I wrote a guide to using RSS to improve your web experience, evade lock-in and duck algorithmic recommendation systems:

https://pluralistic.net/2024/10/16/keep-it-really-simple-stupid/#read-receipts-are-you-kidding-me-seriously-fuck-that-noise

Customizing your browser takes this to the next level, disenshittifying many websites – even if they block or restrict RSS. Most of this stuff only applies to desktop browsers, though. Mobile browsers are far more locked down (even mobile Firefox – remember, every iOS browser, including Firefox, is just a re-skinned version of Safari, thanks to Apple's ban rival browser engines). And of course, apps are the worst. An app is just a website skinned in the right kind of IP to make it a crime to improve it in any way:

https://pluralistic.net/2024/05/07/treacherous-computing/#rewilding-the-internet

And even if you do customize your mobile browser (Android Firefox lets you do some of this stuff), many apps (Twitter, Tumblr) open external links in their own browser (usually an in-app Chrome instance) with all the bullshit that entails.

The promise of locked-down mobile platforms was that they were going to "just work," without any of the confusing customization options of desktop OSes. It turns out that taking away those confusing customization options was an invitation to every enshittifier to turn the web into an unreadable, extractive, nagging mess. This was the foreseeable – and foreseen – consequence of a new kind of technology where everything that isn't mandatory is prohibited:

Note published on March 5, 2026 at 11:01 PM UTC

Today the SEC filed a proposed final judgment to settle their lawsuit against Justin Sun and his businesses for $10 million and no admission of wrongdoing.

Sun has spent between $112 million and $233 million on contributions to Trump-linked crypto firms.

Entity: Justin Sun and Tron // Benefit to entity: SEC enforcement case settled for $10 million fine with no admission of wrongdoing, Criminal investigation likely ended, Justin Sun added to World Liberty Financial advisory board, Tron to go public in the US in a $100 million deal brokered via Dominari Securities (where Eric and Donald Trump Jr. are board members) // Benefit to Trump and family: $100 million to purchase $TRUMP memecoins (announced but unconfirmed), $75 million to purchase $WLFI tokens from the Trump family's World Liberty Financial, $37.7 million to purchase $TRUMP memecoins (via HTX), $20 million to purchase shares of the Trump-linked Alt5 Sigma and more $WLFI (announced but unconfirmed), Listed USD1 for trading on HTX

In January, House Financial Services Ranking Member Maxine Waters sent a letter to SEC Chair Paul Atkins expressing concern over the SEC's "retrenchment from crypto enforcement", citing the Sun case and urging Atkins to hold him accountable.

The SEC Can Still Act to Hold Justin Sun Accountable One case offers the SEC an opportunity to demonstrate to Americans that the SEC still has their back. In February 2025, as part of its efforts to shut down cases holding crypto fraudsters accountable, the SEC asked the court to stay its enforcement action against Justin Sun, founder of the Tron Foundation, SEC v. Sun, et al., Case No. 1:23-cv-02433-ER (S.D.N.Y.). Unlike the other cases detailed above, this case has not yet been dismissed. The SEC’s request to stay the Sun litigation, and subsequent efforts to settle the matter, may have been unduly influenced by Sun’s relationship with the Trump family, including his significant financial contributions to their businesses.19 So that investors harmed by Sun‘s fraudulent activities may be made whole, I ask the to SEC revisit its request to stay its litigation against Sun and renew that action. 
The SEC’s failure to hold Sun accountable suggests that it may be part of a pay-to-play scheme orchestrated by Sun. Specifically, as recently as September 5, 2025, Sun made statements on X suggesting he intended to purchase an additional $10 million worth of $WLFI tokens from World Liberty Financial (WLF), a Trump family business, in an apparent effort to persuade WLF that he is committed to the project, that they should unlock his 545 million $WLFI tokens, and to otherwise curry favor with the Trump family. We are also concerned that a settlement favorable to Sun could undermine U.S. securities regulation and threaten the integrity of U.S. markets by a person and entities located in the People’s Republic of China. On the heels of President Trump’s pardon of Binance founder, CZ, the SEC must continue to pursue material securities fraud matters, including those involving crypto, to protect American retail investors. We ask that the SEC request that the Court lift the stay and that the SEC litigate the case consistent with the facts alleged in its complaint. Alternatively, should the SEC determine that a settlement would be the best outcome for harmed investors, we ask that such a settlement reflect the strength of the SEC’s case and be consistent with the relief it would have obtained had it litigated the case to a favorable judgment. The SEC’s Strong Case Against Justin Sun The SEC’s complaint, filed on March 22, 2023, alleged unlawful conduct spanning several years. The SEC alleged that Sun “engineered the offer and sale of two crypto asset securities called ‘TRX’ and ‘BTT’” to the investing public starting in 2017, but never filed a registration statement for these offerings.20 Sun’s conduct, however, extended beyond registration violations to securities fraud. As the SEC detailed in its complaint, “Sun directed the manipulative wash trading of TRX to create the artificial appearance of legitimate investor interest and keep TRX’s price afloat.”21 Under Sun’s direction, the SEC alleged, employees conducted “hundreds of thousands of TRX wash trades” between accounts that Sun ultimately controlled, with no change in beneficial ownership of the tokens and “no legitimate economic purpose.”22 The SEC claimed that these manipulative trading activities generated a false impression of a liquid market, allowing Sun to sell approximately $31 million worth of tokens to unsuspecting investors.23 The SEC’s complaint also alleged that the scheme was made worse by Sun’s orchestration of an unlawful celebrity promotion campaign.24 The SEC detailed allegations that Sun paid multiple celebrities (who had millions of online followers) to promote TRX and BTT on social media “without disclosing that they had been paid.”25 According to the SEC’s complaint, Sun publicly lied about these arrangements, falsely claiming on Twitter in February 2021 that, “If any celebrities are paid to promote TRON, we require them to disclose,” even as “Sun himself arranged the payments to celebrities and knew those payments were not disclosed.”26 

Chair Atkins has suggested that the crypto cases his agency has dropped were merely over "registration issues" that were "red herrings" from the Biden admin. But the complaint against Sun also alleged serious fraud.

The Commission also alleges that Sun violated the antifraud and market manipulation provisions of the federal securities laws by orchestrating a scheme to artificially inflate the apparent trading volume of TRX in the secondary market. From at least April 2018 through February 2019, Sun allegedly directed his employees to engage in more than 600,000 wash trades of TRX between two crypto asset trading platform accounts he controlled, with between 4.5 million and 7.4 million TRX wash traded daily. This scheme required a significant supply of TRX, which Sun allegedly provided. As alleged, Sun also sold TRX into the secondary market, generating proceeds of $31 million from illegal, unregistered offers and sales of the token. “This case demonstrates again the high risk investors face when crypto asset securities are offered and sold without proper disclosure,” said SEC Chair Gary Gensler. “As alleged, Sun and his companies not only targeted U.S. investors in their unregistered offers and sales, generating millions in illegal proceeds at the expense of investors, but they also coordinated wash trading on an unregistered trading platform to create the misleading appearance of active trading in TRX. Sun further induced investors to purchase TRX and BTT by orchestrating a promotional campaign in which he and his celebrity promoters hid the fact that the celebrities were paid for their tweets.”

In July, shortly after Sun announced his plan to purchase another $100 million of the $TRUMP memecoin, the Sun-involved and -themed SUNDOG memecoin posted a meme showing its corgi mascot holding puppet strings attached to the White House.

https://singletrackworld.com/2018/01/collision-course-why-this-type-of-road-junction-will-keep-killing-cyclists/

There are lots of intersections that are dangerous for cyclists, of course, but what made Ipsley Cross so lethal was a kind of eldritch geometry that let the cyclist and the driver see each other a long time before the collision, while also providing the illusion that they were not going to collide, until an instant before the crash.

This intersection is an illustration of a phenomenon called "constant bearing, decreasing range," which (the article notes) had long been understood by sailors as a reason that ships often collide. I'm not going to get into the trigonometry here (the Singletrack article does a great job of laying it out).

I am, however, going to use this as a metaphor: there is a kind of collision that is almost always fatal because its severity isn't apparent until it is too late to avert the crash. Anyone who's been filled with existential horror at the looming climate emergency can certainly relate.

The metaphor isn't exact. "Constant bearing, decreasing range" is the result of an optical illusion that makes it seem like things are fine right up until they aren't. Our failure to come to grips with the climate emergency is (partly‡) caused by a different cognitive flaw: the fact that we struggle to perceive the absolute magnitude of a series of slow, small changes.

‡The other part being the corrupting influence of corporate money in politics, obviously

This is the phenomenon that's invoked in the parable of "boiling a frog." Supposedly, if you put a frog in a pot of water at a comfortable temperature and then slowly warm the water to boiling, the frog will happily swim about even as it is cooked alive. In this metaphor, the frog can only perceive relative changes, so all that it senses is that the water has gotten a little warmer, and a small change in temperature isn't anything to worry about, right? The fact that the absolute change to the water is lethal does not register for our (hypothetical) frog.

Now, as it happens, frogs will totally leap clear of a pot of warming water when it reaches a certain temperature, irrespective of how slowly the temperature rises. But the metaphor persists, because while it does not describe the behavior of frogs in a gradually worsening situation, it absolutely describes how humans respond to small, adverse changes in our environment.

Take moral compromises: most of us set out to be good people, but reality demands small compromises to our ethics. So we make a small ethical compromise, and then before long, circumstances demand another compromise, and then another, and another, and another. Taken in toto, these compromises represent a severe fall from our personal standards, but so long as they are dripped out in slow and small increments, too often we rationalize our way into them: each one is only a small compromise, after all:

https://pluralistic.net/2020/02/19/pluralist-19-feb-2020/#thinkdifferent

Back to the climate emergency: for the first 25 years after NASA's James Hansen testified before Congress about "global heating," the changes to our world were mostly incremental: droughts got a little worse, as did floods. We had a few more hurricanes. Ski seasons got shorter. Heat waves got longer. Taken individually, each of these changes was small enough for our collective consciousness to absorb as within the bounds of normalcy, or, at worst, just a small worsening. Sure, there could be a collision on the horizon, but it wasn't anything urgent enough to justify the massive effort of decarbonizing our energy and transportation:

https://locusmag.com/feature/cory-doctorow-the-swerve/

It's not that we're deliberately committing civilizational suicide, it's just that slow-moving problems are hard to confront, especially in a world replete with fast-moving, urgent problems.

But crises precipitate change:

https://www.youtube.com/watch?v=FrEdbKwivCI

Before 2022, Europe was doing no better than the rest of the world when it came to confronting the climate emergency. Its energy mix was still dominated by fossil fuels, despite the increasing tempo of wildfires and floods and the rolling political crises touched off by waves of climate refugees. These were all dire and terrifying, but they were incremental, a drip-drip-drip of bad and worsening news.

Then Putin invaded Ukraine, and the EU turned its back on Russian gas and oil. Overnight, Europe was plunged into an urgent energy crisis, confronted with the very real possibility that millions of Europeans would shortly find themselves shivering in the dark – and not just for a few nights, but for the long-foreseeable future.

At that moment, the slow-moving crisis of the climate became the Putin emergency. The fossil fuel industry – one of the most powerful and corrupting influences in Brussels and around the world – was sidelined. Europe raced to solarize. In three short years, the continent went from decades behind on its climate goals to a decade ahead on them:

https://pluralistic.net/2025/10/11/cyber-rights-now/#better-late-than-never

Putin could have continued to stage minor incursions on Ukraine, none of them crossing any hard geopolitical red lines, and Europe would likely have continued to rationalize its way into continuing its reliance on Russia's hydrocarbon exports. But Putin lacked the patience to continue nibbling away at Ukraine. He tried to gobble it all down at once, and then everything changed.

There is a sense, then, in which Putin's impatient aggression was a feature, not a bug. But for Putin's lack of executive function, Ukraine might still be in danger of being devoured by Russia, but without Europe taking any meaningful steps to come to its aid – and Europe's solar transition would still be decades behind schedule.

Enshittification is one of those drip-drip-drip phenomena, too. Platform bosses have a keen appreciation of how much value we deliver to one another – community, support, mutual aid, care – and they know that so long as we love each other more than we hate the people who own the platforms, we'll likely stay glued to them. Mark Zuckerberg is a master of "twiddling" the knobs on the back-ends of his platforms, announcing big, enshittifying changes, and then backing off on them to a level that's shittier than it used to be, but not as shitty as he'd threatened:

https://pluralistic.net/2023/02/19/twiddler/

Zuck is a colossal asshole, a man who founded his empire in a Harvard dorm room to nonconsensually rate the fuckability of his fellow undergrads, a man who knowingly abetted a genocide, a man who cheats at Settlers of Catan:

https://pluralistic.net/2025/04/23/zuckerstreisand/#zdgaf

But despite all these disqualifying personality defects, Mark Zuckerberg has one virtue that puts him ahead of his social media competitor Elon Musk: Zuck has a rudimentary executive function, and so he is capable of backing down (sometimes, temporarily) from his shittiest ideas.

Contrast that with Musk's management of Twitter. Musk invaded Twitter the same year Putin invaded Ukraine, and embarked upon a string of absolutely unhinged and incontinent enshittificatory gambits that lacked any subtlety or discretion. Musk didn't boil the frog – he took one of his flamethrowers to it.

Millions of people were motivated to hop out of Musk's Twitter pot. But millions more – including me – found ourselves mired there. It wasn't that we liked Musk's Twitter, but we had more reasons to stay than we had to go. For me, the fact that I'd amassed half a million followers since some old pals messaged me to say they'd started a new service called "Twitter" meant that leaving would come at a high price to my activism and my publishing career.

But Musk kept giving me reasons to reassess my decision to stay. Very early into the Musk regime, I asked my sysadmin Ken Snider to investigate setting up a Bluesky server that I could move to. I was already very active on Mastodon, which is designed to be impossible to enshittify the way Musk had done to Twitter, because you can always move from one Fediverse server to another if the management turns shitty:

https://pluralistic.net/2022/12/23/semipermeable-membranes/

But for years, Bluesky's promise of federation remained just that – a promise. Technically, its architecture dangled the promise of multiple, independent Bluesky servers, but practically, there was no way to set this up:

https://pluralistic.net/2023/08/06/fool-me-twice-we-dont-get-fooled-again/

But – to Bluesky's credit – they eventually figured it out, and published the tools and instructions to set up your own Bluesky servers. Ken checked into it, and told me that it was all do-able, but not until a planned hardware upgrade to the Linux box he keeps in a colo cage in Toronto was complete. That upgrade happened a couple months ago, and yesterday, Ken let me know that he'd finished setting up a Bluesky server, just for me. So now I'm on Bluesky, at @doctorow.pluralistic.net:

https://bsky.app/profile/doctorow.pluralistic.net

I am on Bluesky, the service, but I am not a user of Bluesky, the company. That means that I'm able to interact with Bluesky users without clicking through Bluesky's abominable terms of service, through which you permanently surrender your right to sue the company (even if you later quit Bluesky and join another server!):

https://pluralistic.net/2025/08/15/dogs-breakfast/#by-clicking-this-you-agree-on-behalf-of-your-employer-to-release-me-from-all-obligations-and-waivers-arising-from-any-and-all-NON-NEGOTIATED-agreements

Remember: I knew and trusted the Twitter founders and I still got screwed. It's not enough for the people who run a service to be good people – they also have to take steps to insulate themselves (and their successors) from the kind of drip-drip-drip rationalizations that turn a series of small ethical waivers into a cumulative avalanche of pure wickedness:

https://pluralistic.net/2024/12/14/fire-exits/#graceful-failure-modes

Bluesky's "binding arbitration waiver" does the exact opposite: rather than insulating Bluesky's management from their own future selves' impulse to do wrong, a binding arbitration waiver permanently insulates Bluesky from consequences if (when) they yield the temptation to harm their users.

But Bluesky's technical architecture offers a way to eat my cake and have it, too. By setting up a Bluesky (the service) account on a non-Bluesky (the company) server, I can join a social space that has lots of people I like, and lots of interesting technical innovations, like composable moderation, without submitting to the company's unacceptable terms of service:

https://bsky.social/about/blog/4-13-2023-moderation

If Twitter was on the same slow enshittification drip-drip-drip of the pre-Musk years, I might have set up on Bluesky and stayed on Twitter. But thanks to Musk and his frog blowtorch, I'm able to make a break. For years now, I have posted this notice to Twitter nearly every day:

Twitter gets worse every single day. Someday it will degrade beyond the point of usability. The Fediverse is our best hope for an enshittification-resistant alternative. I'm @pluralistic@mamot.fr.

Today, I am posting a modified version, which adds:

If you'd like to follow me on Bluesky, I'm @doctorow.pluralistic.net. This is the last thread I will post to Twitter.

Crises precipitate change. All things being equal, the world would be a better place without Vladimir Putin or Elon Musk or Donald Trump in it. But these incontinent, impatient, terrible men do have a use: they transform slow-moving crises that are too gradual to galvanize action into emergencies that can't be ignored. Putin pushed the EU to break with fossil fuels. Musk pushed millions into federated social media. Trump is ushering in a post-American internet:

https://pluralistic.net/2026/01/01/39c3/#the-new-coalition

If you're reading this on Twitter, this is the long-promised notice that I'm done here. See you on the Fediverse, see you on Bluesky – see you in a world of enshittification-resistant social media.

It's been fun, until it wasn't.

Pluralistic: Supreme Court saves artists from AI (03 Mar 2026)


Today's links


The Supreme Court building. It has been tinted sepia. Floating in front of it are a 1920s-era Supreme Court, tinted blue-green, their heads replaced with the glaring red eyes of HAL 9000 from Stanley Kubrick's '2001: A Space Odyssey,' and their hands tinted hot pink. They have been distorted with a ripple effect and TV scan lines. The sky is full of dark clouds.

Supreme Court saves artists from AI (permalink)

The Supreme Court has just turned down a petition to hear an appeal in a case that held that AI works can't be copyrighted. By turning down the appeal, the Supreme Court took a massively consequential step to protect creative workers' interests:

https://www.theverge.com/policy/887678/supreme-court-ai-art-copyright

At the core of the dispute is a bedrock of copyright law: that copyright is for humans, and humans alone. In legal/technical terms, "copyright inheres at the moment of fixation of a work of human creativity." Most people – even people who work with copyright every day – have not heard it put in those terms. Nevertheless, it is the foundation of international copyright law, and copyright in the USA.

Here's what it means, in plain English:

a) When a human being,

b) does something creative; and

c) that creative act results in a physical record; then

d) a new copyright springs into existence.

For d) to happen, a), b) and c) all have to happen first. All three steps for copyright have been hotly contested over the years. Remember the "monkey selfie," in which a photographer argued that he was entitled to the copyright after a monkey pointed a camera at itself and pressed the shutter button? That image was not copyrightable, because the monkey was a monkey, not a human, and copyright is only for humans:

https://en.wikipedia.org/wiki/Monkey_selfie_copyright_dispute

Then there's b), "doing something creative." Copyright only applies to creative work, not work itself. It doesn't matter how hard you labor over a piece of "IP" – if that work isn't creative, there's no copyright. For example, you can spend a fortune creating a phone directory, and you will get no copyright in the resulting work, meaning anyone can copy and sell it:

https://en.wikipedia.org/wiki/Feist_Publications,_Inc._v._Rural_Telephone_Service_Co.

If you mix a little creative labor with the hard work, you can get a little copyright. A directory of "all the phone numbers for cool people" can get a "thin" copyright over the arrangement of facts, but such a copyright still leaves space for competitors to make many uses of that work without your permission:

https://pluralistic.net/2021/08/14/angels-and-demons/#owning-culture

Finally, there's c): copyright is for tangible things, not intangibles. Part of the reason choreographers created a notation system for dance moves is that the moves themselves aren't copyrightable:

https://en.wikipedia.org/wiki/Dance_notation

The non-copyrightability of movement is (partly) why the noted sex-pest and millionaire grifter Bikram Choudhury was blocked from claiming copyright on ancient yoga poses (the other reason is that they are ancient!):

https://en.wikipedia.org/wiki/Copyright_claims_on_Bikram_Yoga

Now, AI-generated works are certainly tangible (any work by an AI must involve magnetic traces on digital storage media). The prompts for an AI output can be creative and thus copyrightable (in the same way that notes to a writers' room or from an art-director are). But the output from the AI cannot be copyrighted, because it is not a work of human authorship.

This has been the position of the US Copyright Office from the start, when AI prompters started sending in AI-generated works and seeking to register copyrights in them. Stephen Thaler, a computer scientist who had prompted an image generator to produce a bitmap, kept appealing the Copyright Office's decision, seemingly without regard to the plain facts of the case and the well-established limits of copyright. By attempting to appeal his case all the way to the Supreme Court, Thaler has done every human artist a huge boon: his weak, ill-conceived case was easy for the Supreme Court to reject, and in so doing, the court has cemented the non-copyrightability of AI works in America.

You may have heard the saying, "Hard cases make bad law." Sometimes, there are edge-cases where following the law would result in a bad outcome (think of a Fourth Amendment challenge to an illegal search that lets a murderer go free). In these cases, judges are tempted to interpret the law in ways that distort its principles, and in so doing, create a bad precedent (the evidence from a bad search is permitted, and so cops stop bothering to get a warrant before searching people).

This is one of the rare instances in which a bad case made good law. Thaler's case wasn't even close – it was an absolute loser from the jump. Normally, plaintiffs give up after being shot down by an agency like the Copyright Office or by a lower court. But not Thaler – he stuck with it all the way to the highest court in the land, bringing clarity to an issue that might have otherwise remained blurry and ill-defined for years.

This is wonderful news for creative workers. It means that our bosses must pay humans to do work if they want to be granted copyright on the things they want to sell. The more that humans are involved in the creation of a work, the stronger the copyright on that work becomes – which means that the less a human contributes to a creative work, the harder it will be to prevent others from simply taking it and selling it or giving it away.

This is so important. Our bosses do not want to pay us. When our bosses sue AI companies, it's not because they want to make sure we get paid.

The many pending lawsuits – from news organizations like the New York Times, wholesalers like Getty Images, and entertainment empires like Disney – all seek to establish that training an AI model is a copyright infringement. This is wrong as a technical matter: copyright clearly permits making transient copies of published works for the purpose of factual analysis (otherwise every search engine would be illegal). Copyright also permits performing mathematical analysis on those transient copies. Finally, copyright permits the publication of literary works (including software programs) that embed facts about copyrighted works – even billions of works:

https://pluralistic.net/2023/09/17/how-to-think-about-scraping/

Sure, you can infringe copyright with an AI model – say, by prompting it to produce infringing images. But the mere fact that a technology can be used to infringe copyright doesn't make the technology itself infringing (otherwise every printing press, camera, and computer would be illegal):

https://en.wikipedia.org/wiki/Sony_Corp._of_America_v._Universal_City_Studios,_Inc.

Of course, the fact that copyright currently permits training models doesn't mean that it must. Copyright didn't come down from a mountain on two stone tablets. It's just a law, and laws can be amended. I think that amending copyright to ban training a model would inflict substantial collateral damage on everything from search engines to scholarship, but perhaps you disagree. Maybe you think that you could wordsmith a new copyright law that bans training without whacking a bunch of socially beneficial activities.

Even if that's so, it still wouldn't help artists.

To understand why, consider Universal and Disney's lawsuit against Midjourney. The day that lawsuit dropped, I got a press release from the RIAA, signed by its CEO, Mitch Glazier. Here's how it began:

There is a clear path forward through partnerships that both further AI innovation and foster human artistry. Unfortunately, some bad actors – like Midjourney – see only a zero-sum, winner-take-all game.

The RIAA represents record labels, not film studios, but thanks to vertical integration, the big film studios are also the big record labels. That's why the RIAA alerted the press to its position on this suit.

There's two important things to note about the RIAA press release: how it opened, and how it closed. It opens by stating that the companies involved want "partnerships" with AI companies. In other words, if they establish that they have the right to control training on their archives, they won't use that right to prevent the creation of AI models that compete with creative workers. Rather, they will use that right to get paid when those models are created.

Expanding copyright to cover models isn't about preventing generative AI technologies – it's about ensuring that these technologies are licensed by incumbent media companies. This licensure would ensure that media companies would get paid for training, but it would also let them set the terms on which the resulting models were used. The studios could demand that AI companies put "guardrails" on the resulting models to stop them from being used to output things that might compete with the studios' own products.

That's what the opening of this press-release signifies, but to really understand its true meaning, you have to look at the closing of the release: the signature at the bottom of it, "Mitch Glazier, CEO, RIAA."

Who is Mitch Glazier? Well, he used to be a Congressional staffer. He was the guy responsible for sneaking a clause into an unrelated bill that repealed "termination of transfer" for musicians. "Termination" is a part of copyright law that lets creators take back their rights after 35 years, even if they originally signed a contract for a "perpetual license."

Under termination, all kinds of creative workers who got royally screwed at the start of their careers were able to get their copyrights back and re-sell them. The primary beneficiaries of termination are musicians, who signed notoriously shitty contracts in the 1950s-1980s:

https://pluralistic.net/2021/09/26/take-it-back/

When Mitch Glazier snuck a termination-destroying clause into legislation, he set the stage for the poorest, most abused, most admired musicians in recording history to lose access to money that let them buy a couple bags of groceries and make the rent. He condemned these beloved musicians to poverty.

What happened next is something of a Smurfs Family Christmas miracle. Musicians were so outraged by this ripoff, and their fans were so outraged on their behalf, that Congress convened a special session solely to repeal the clause that Mitch Glazier tricked them into voting for. Shortly thereafter, Glazier was out of Congress:

https://en.wikipedia.org/wiki/Mitch_Glazier

But this story has a happy ending for Glazier, too – he might have been out of his government job, but he had a new gig, as CEO of the Recording Industry Association of America, where he earns more than $1.3 million/year to carry on the work he did in Congress – serving the interests of the record labels:

https://projects.propublica.org/nonprofits/organizations/131669037

Mitch Glazier serves the interests of the labels, not musicians. He can't serve both interests, because every dime a musician takes home is a dime that the labels don't get to realize as profits. Labels and musicians are class enemies. The fact that many musicians are on the labels' side when they sue AI companies does not mean that the labels are on the musicians' side.

What will the media companies do if they win their lawsuits? Glazier gives us the answer in the opening sentence of his press release: they will create "partnerships" with AI companies to train models on the work we produce.

This is the lesson of the past 40 years of copyright expansion. For 40 years, we have expanded copyright in every way: copyright lasts longer, covers more works, prohibits more uses without licenses, establishes higher penalties, and makes it easier to win those penalties.

Today, the media industry is larger and more profitable than at any time, and the share of those profits that artists take home is smaller than ever.

How has the expansion of copyright led to media companies getting richer and artists getting poorer? That's the question that Rebecca Giblin and I answer in our 2022 book Chokepoint Capitalism. In a nutshell: in a world of five publishers, four studios, three labels, two app companies and one company that controls all ebooks and audiobooks, giving a creative worker more copyright is like giving your bullied kid extra lunch money. It doesn't matter how much lunch money you give that kid – the bullies will take it all, and the kid will go hungry:

https://pluralistic.net/2022/08/21/what-is-chokepoint-capitalism/

Indeed, if you keep giving that kid more lunch money, the bullies will eventually have enough dough that they'll hire a fancy ad-agency to blitz the world with a campaign insisting that our schoolkids are all going hungry and need even more lunch money (they'll take that money, too).

When Mitch Glazier – who got a $1m+/year job for the labels after attempting to pauperize musicans – writes on behalf of Disney in support of a copyright suit to establish that copyright prevents training a model without a license, he's not defending creative workers. Disney, after all, is the company that takes the position that if it buys another company, like Lucasfilm or Fox, that it only acquires the right to use the works we made for those companies, but not the obligation to pay us when they do:

https://pluralistic.net/2021/04/29/writers-must-be-paid/#pay-the-writer

If a new, unambiguous copyright over model training comes into existence – whether through a court precedent or a new law – then all our contracts will be amended to non-negotiably require us to assign that right to our bosses. And our bosses will enter into "partnerships" to train models on our works. And those models will exist for one purpose: to let them create works without paying us.

The market concentration that lets our bosses dictate terms to us is getting much worse, and it's only speeding up. Getty Images – who sued Stability AI over image generation – is merging with Shutterstock:

https://globalcompetitionreview.com/gcr-usa/article/photographers-alarmed-gettyshutterstock-merger

And Paramount is merging with Warners:

https://pluralistic.net/2026/02/28/golden-mean/#reality-based-community

This is where this new Supreme Court action comes in. A new copyright that covers training is just one more thing these increasingly powerful members of this increasingly incestuous cartel can force us to sign away. That new copyright isn't something for us to bargain with, it's something we'll bargain away.

But the fact that the works that a model produces are automatically in the public domain is something we can't bargain away. It's a legal fact, not a legal right. It means that the more humans there are involved in the creation of a final work, the more copyrightable that work is.

Media bosses love AI because it dangles the tantalizing possibility of running a business without ego-shattering confrontations with creative workers who know how to do things. It's the solipsistic fantasy of a world without workers, in which a media boss conceives of a "product," prompts a sycophantic AI, and receives an item that's ready for sale:

https://pluralistic.net/2026/01/05/fisher-price-steering-wheel/#billionaire-solipsism

Many bosses know this isn't within reach. They imagine that they'll get the AI to shit out a script and then pay a writer on the cheap to "polish" it. They think they'll get an AI to shit out a motion sequence, a still, or a 3D model and then pay a human artist pennies to put the "final touches" on it. But the Copyright Office's position is that only those human contributions are eligible for a copyright: a few editorial changes, a few pixels or vectors rearranged. Everything else is in the public domain.

Here's the cool part: the only thing our bosses hate more than paying us is when other people take their stuff without paying for it. To achieve the kind of control they demand, they will have to pay us to make creative works.

What's more, the fact that AI-generated works are in the public domain leaves a lot of uses that don't harm creative workers intact. You can amuse yourself and your friends with all the AI slop you can generate; the fact that it's not copyrightable doesn't matter to that use. I happen to think AI "art" is shit, but you do you:

https://pluralistic.net/2024/05/13/spooky-action-at-a-close-up/#invisible-hand

This also means that if you're a writer who likes to brainstorm with a chatbot as you develop an idea, that's fine, so long as the AI's words don't end up in the final product. Creative workers already assemble "mood boards" and clippings for inspiration – so long as these aren't incorporated into the final work, that's fine.

That's just what the Hollywood writers bargained for in their historic strike over AI. They retained the right to use AI if they wanted to, but their bosses couldn't force them to:

https://pluralistic.net/2023/10/01/how-the-writers-guild-sunk-ais-ship/

The Writers Guild were able to bargain with the heavily concentrated studios because they are organized in a union. Not just any union, either: the Writers Guild (along with the other Hollywood unions) are able to undertake "sectoral bargaining" – that's when a union can negotiate a contract with all the employers in a sector at once.

Sectoral bargaining was once the standard for labor relations, but it was outlawed in the 1947 Taft-Hartley Act, which clawed back many of the important labor rights established with the New Deal's National Labor Relations Act. To get Taft-Hartley through Congress, its authors had to compromise by grandfathering in the powerful Hollywood unions, who retained their right to sectoral bargaining. More than 75 years later, that sectoral bargaining right is still protecting those workers.

Our bosses tell us that we should side with them in demanding a new law: a copyright law that covers training an AI model. The mere fact that our bosses want this should set off alarm bells. Just because we're on their side, it doesn't mean they're on our side. They are not.

If we're going to use our muscle to fight for a new law, let it be a sectoral bargaining law – one that covers all workers. You can tell that this would be good for us because our bosses would hate it, and every other worker in America would love it. The Writers Guild used sectoral bargaining to achieve something that 40 years of copyright expansion failed at: it made creative workers richer, rather than giving us another way to be angry about how our work is being used.

Pluralistic: No one wants to read your AI slop (02 Mar 2026)


Today's links


A 1913 picture postcard depicting the flood of Carey, OH's Main Street, as two men in a canoe paddle down the flooded street. A reflection of the hostile, glaring red eye of HAL 9000 from Stanley Kubrick's '2001: A Space Odyssey' ripples in the water around them.

No one wants to read your AI slop (permalink)

Everyone knows (or should know) that as fascinating as your dreams are to you, they are eye-glazingly dull to everyone else. Perhaps you have a friend or two who will tolerate you recounting your dreams at them (treasure those friends), but you should never, ever presume that other people want to hear about your dreams.

The same is true of your conversations with chatbots. Even if you find these conversations interesting, you should never assume that anyone else will be entertained by them. In the absence of an explicit reassurance to the contrary, you should presume that recounting your AI chatbot sessions to your friends is an imposition on the friendship, and forwarding the transcripts of those sessions doubly so (perhaps triply so, given the verbosity of chatbot responses).

I will stipulate that there might be friend groups out there where pastebombs of AI chat transcripts are welcome, but even if you work in such a milieu, you should never, ever assume that a stranger wants to see or hear about your AI "conversations." Tagging a chatbot into a social media conversation with a stranger and typing, "Hey Grok‡, what do you think of that?" is like masturbating in front of a stranger.

‡ Ugh

It's rude. It's an imposition. It's gross.

There's an even worse circle of hell than the one you create when you nonconsensually add a chatbot to a dialog: the hell that comes from reading something a stranger wrote, and then asking a chatbot to generate "commentary" on it and emailing it to that stranger.

Even the AI companies pitching their products claim that they need human oversight because they are prone to errors (including the errors that the companies dress up by calling them "hallucinations"). If you've read something you disagree with but don't understand well enough to rebut, and you ask an AI to generate a rebuttal for you, you still don't understand it well enough to rebut it.

You haven't generated a rebuttal: you have generated a blob of plausible sentences that may or may not constitute a valid critique of the work you're upset with – but until a human being who understands the issue goes through the AI output line by line and verifies it, it's just stochastic word-salad.

Once again: the act of prompting a sentence generator to create a rebuttal-shaped series of sentences does not impart understanding to the prompter. In the dialog between someone who's written something and someone who disagrees with it, but doesn't understand it well enough to rebut it, the only person qualified to evaluate the chatbot's output is the original author – that is, the stranger you've just emailed a chat transcript to.

Emailing a stranger a blob of unverified AI output is not a form of dialogue – it's an attempt to coerce a stranger into unpaid labor on your behalf. Strangers are not your "human in the loop" whose expensive time is on offer to painstakingly work through the plausible sentences a chatbot made for you for free.

Remember: even the AI companies will tell you that the work of overseeing an AI's output is valuable labor. The fact that you can costlessly (to you) generate infinite volumes of verbose, plausible-seeming topical sentences in no way implies that the people who actually think about things and then write them down have the time to mark your chatbot's homework.

That is a fatal flaw in the idea that we will increase our productivity by asking chatbots to summarize things we don't understand: by definition, if we don't understand a subject, then we won't be qualified to evaluate the summary, either.

There simply is no substitute for learning about a subject and coming to understand it well enough to advance the subject, whether by contributing your own additions or by critiquing its flaws. That's not to say that we shouldn't aspire to participate in discourse about areas that seem interesting or momentous – but asking a chatbot to contribute on your behalf does not impart insight to you, and it is a gross imposition on people who have taken the time to understand and participate using their own minds and experience.

Pluralistic: California can stop Larry Ellison from buying Warners (28 Feb 2026)


Today's links


The Warner tower, toppling over, surmounted by the bear from the California flag, posed on an old timey map of Los Angeles.

California can stop Larry Ellison from buying Warners (permalink)

For months, the hottest will-they/won't-they drama in Hollywood concerned the suitors for Warners, up for sale again after being bought, merged, looted and wrecked by the eminently guillotineable David Zaslav:

https://www.youtube.com/watch?v=izC9o3LhnVk

From the start, it was clear that Warners would be sucked dry and discarded, but the Trump 2024 election turned the looting of Warners' corpse into a high-stakes political drama.

On the one hand, you had Netflix, who wanted to buy Warners and use them to make good movies, but also to kill off movie theaters forever by blocking theatrical distribution of Warners' products.

On the other hand, you had Paramount, owned by the spray-tan cured tech billionaire jerky Larry Ellison, though everyone is supposed to pretend that Ellison's do-nothing/know-nothing/amounts-to-nothing son Billy (or whatever who cares) Ellison is running the show.

Ellison's plan was to buy Warners and fold it into the oligarchic media capture project that's seen Ellison replace the head of CBS with the tedious mediocrity Bari Weiss:

https://www.wnycstudios.org/podcasts/otm/articles/the-centurylong-capture-of-us-media

This is a multi-pronged media takeover that includes Jeff Bezos neutering the Washington Post, Elon Musk turning Twitter into a Nazi bar, and Trump stealing Tiktok and giving it to Larry Ellison. If Ellison gains control over Warners, you can add CNN to the nonsense factory.

But for a while there, it looked like the Ellisons would lose the bidding. Little Timmy (or whatever who cares) Ellison only has whatever money his dad parks in his bank account for tax purposes, and Larry Ellison is so mired in debt that one margin call could cost him his company, his fighter jet, and his Hawaiian version of Little St James Island.

Warners' board may not give a shit about making good media or telling the truth or staving off fascism, but they do want to get paid, and Netflix has money in the bank, whereas Ellison only has the bank's money (for now).

But last week, the dam broke: Warners' board indicated they'd take Paramount's offer, and Netflix withdrew their offer, and so that's that, right? It's not like Trump's FTC is going to actually block this radioactively illegal merger, despite the catastrophic corporate consolidation that would result, with terrible consequences for workers, audiences, theaters, cable operators and the entire supply chain.

Not so fast! The Clayton Act – which bars this kind of merger – is designed to be enforced by the feds, state governments, and private parties. That means that California AG Rob Bonta can step in to block this merger, which he's getting ready to do:

https://prospect.org/2026/02/27/states-can-block-paramount-warner-deal/

As David Dayen writes in The American Prospect, state AGs block mergers all the time, even when the feds decline to step in – just a couple years ago, Washington state killed the Kroger/Albertsons merger.

The fact that antitrust laws can be enforced at the state level is a genius piece of policy design. As the old joke goes, "AG" stands for "aspiring governor," and the fact that state AGs can step in to rescue their voters from do-nothing political hacks in Washington is catnip for our nation's attorneys general.

Bonta is definitely feeling his oats: he's also going after Amazon for price-fixing, picking up a cause that Trump dropped after Jeff Bezos ordered the Washington Post to cancel its endorsement of Kamala Harris, paid a million bucks to sit on the inaugural dais, millions more to fund the White House Epstein Memorial Ballroom and $40m more to make an unwatchable turkey of a movie about Melania Trump.

Can you imagine how stupid Bezos is going to feel when all of his bribes to Trump cash out to nothing after Rob Bonta publishes Amazon's damning internal memos and then fines the company a gazillion dollars?

It's a testament to the power of designing laws so they can be enforced by multiple parties. And as cool as it is to have a law that state AGs can enforce, it's way cooler to have a law that can be enforced by members of the public.

This is called a "private right of action" – the thing that lets impact litigation shops like Planned Parenthood, EFF, and the ACLU sue over violations of the public's rights. The business lobby hates the private right of action, because they think (correctly) that they can buy off enough regulators and enforcers to let them get away with murder (often literally), but they know they can't buy off every impact litigation shop and every member of the no-win/no-fee bar.

For decades, corporate America has tried to abolish the public's right to sue companies under any circumstances. That's why so many terms of service now feature "binding arbitration waivers" that deny you access to the courts, no matter how badly you are injured:

https://pluralistic.net/2025/10/27/shit-shack/#binding-arbitration

But long before Antonin Scalia made it legal to cram binding arbitration down your throat, corporate America was pumping out propaganda for "tort reform," spreading the story that greedy lawyers were ginning up baseless legal threats to extort settlements from hardworking entrepreneurs. These stories are 99.9% bullshit, including urban legends like the "McDonald's hot coffee" lawsuit:

https://pluralistic.net/2022/06/12/hot-coffee/#mcgeico

Ever since Reagan, corporate America has been on a 45-year winning streak. Nothing epitomizes the arrogance of these monsters more than the GW Bush administration's sneering references to "the reality-based community":

We're an empire now, and when we act, we create our own reality. And while you're studying that reality – judiciously, as you will – we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors…and you, all of you, will be left to just study what we do.

https://en.wikipedia.org/wiki/Reality-based_community

Giving Ellison, Bezos and Musk control over our media seems like the triumph of billionaires' efforts to "create their own reality," and indeed, for years, they've been able to gin up national panics over nothingburgers like "trans ideology," "woke" and "the immigration crisis."

But just lately, that reality-creation machine has started to break down. Despite taking over the press, locking every reality-based reporter out of the White House, and getting Musk, Zuck and Ellison to paint their algorithms spray-tan orange, people just fucking hate Trump.

Despite the full-court press – from both the Dem and the GOP establishment – to deny the genocide in Gaza and paint anyone (especially Jews like me) who condemn the slaughter as "antisemites," Americans condemn Israel and are fully in the tank for Palestinians:

Despite throwing massive subsidies at coal and tying every available millstone around renewables' ankles before throwing all the solar panels and windmills into the sea, renewables are growing and – to Trump's great chagrin – oil companies can't find anyone to loan them the money they need to steal Venezuela's oil:

Reality turns out to be surprisingly stubborn, and what's more, it has a pronounced left-wing bias. Putting little Huey (or whatever who cares) Ellison in charge of Warners will be bad news for the news, for media, for movies and TV, and for my neighbors in Burbank. But when it comes to shaping the media, Freddy (or whatever who cares) Ellison will continue to eat shit.

Pluralistic: If you build it (and it works), Trump will come (and take it) (26 Feb 2026)


Today's links


Uncle Sam, peering through a magnifying glass at the planet Earth, which is in the palm of his other hand. His hair has been replaced with a Trump wig and his skin has been tinted Cheeto orange. The background is the Great Seal of the USA, and the arrows in the eagle's claw have been replaced with a bundle of glowing fiber optics.

If you build it (and it works), Trump will come (and take it) (permalink)

Crises precipitate change: Trump's incontinent belligerence spurred the world to long-overdue action on "digital sovereignty," as people woke up to the stark realization that a handful of Trump-aligned giant tech firms could shut down their governments, companies and households at the click of a mouse.

This has been a long, long time coming. Long before Trump, the Snowden revelations made it clear that the US government had weaponized its position as the world's IT export powerhouse and the interchange hub for the world's transoceanic fiber links, and was actively spying on everyone – allies and foes, presidents and plebs – to attain geopolitical and commercial advantages for America. Even after that stark reminder, the world continued to putter along, knowing that the US had planted demolition charges in its digital infrastructure, but praying that the "rules-based international order" would stop America from pushing the button.

Now, more than a decade into the Trump era, the world is finally confronting the reality that they need to get the hell off of American IT, and transition to open, transparent and verifiable alternatives for their administrative tools, telecoms infrastructure and embedded systems for agriculture, industry and transportation. And not a moment too soon:

https://pluralistic.net/2026/01/01/39c3/#the-new-coalition

But building the post-American internet is easier said than done. There remain huge, unresolved questions about the best way to proceed.

One thing is clear: we will need new systems: the aforementioned open, transparent, verifiable code and hardware. That's a huge project, but the good news is that it benefits tremendously from scale, which means that as countries, businesses and households switch to the post-American internet, there will be ever more resources to devote to building, maintaining and improving this project. That's how scientific endeavors work: they're global collaborations that allow multiple parties to simultaneously attack the problems from many angles at once. Think of the global effort to sequence, understand, and produce vaccines for Covid 19.

Developing the code and hardware for the post-American internet scales beautifully, making it unique among the many tasks posed by the post-American world. Other untrustworthy US platforms – such as the dollar, or the fiber links that make interconnection in the USA – are hampered by scale. The fact that hundreds of countries use the dollar and rely on US fiber connections makes replacing them harder, not easier:

https://pluralistic.net/2025/11/26/difficult-multipolarism/#eurostack

Building the post-American internet isn't easy, but there's a clear set of construction plans. What's far less clear is how we transition to the post-American internet. How do people, organizations and governments that currently have their data locked up in US Big Tech silos get it off their platforms and onto new, open, transparent, verifiable successors? Literally: how do you move the data from the old system to the new one, preserving things like edit/view permissions, edit histories, and other complex data-structures that often have high-stakes attached to them (for example, many organizations and governments are legally required to maintain strict view/edit permissions for sensitive data, and must preserve the histories of their documents).

On top of that, there's all the systems that we use to talk to one another: media services from Instagram to Tiktok to Youtube; chat services from iMessage to Discord. It's easy enough to build alternatives to these services – indeed, they already exist, though they may require additional engineering to scale them up for hundreds of millions or billions of users – but that's only half the battle. What do we do about the literal billions of people who are already using the American systems?

This is where the big divisions appear. In one camp, you have the "if you build it, they will come" school, who say that all we need to do is make our services so obviously superior to the legacy services that America has exported around the world and people will just switch. This is a very seductive argument. After all, the American systems are visibly, painfully defective: riddled with surveillance and ads, powered by terrible algorithms, plagued by moderation failures.

But waiting for people to recognize the superiority of your alternatives and jumping ship is a dead end. It completely misapprehends the reason that users are still on legacy social media and other platforms. People don't use Instagram because they love Mark Zuckerberg; they use it because they love their friends more than they hate Mark Zuckerberg:

https://pluralistic.net/2026/01/30/zucksauce/#gandersauce

What's more, Zuckerberg knows this. He knows that users of his service are hamstrung by the "collective action problem" of getting the people who matter to you to agree on when it's time to leave a service, and on which service is a safe haven to flee to:

https://pluralistic.net/2022/10/29/how-to-leave-dying-social-media-platforms/

The reason Zuckerberg knows this is that he had to contend with it at the dawn of Facebook, when the majority of social media users were locked into an obviously inferior legacy platform called Myspace. Zuckerberg promised Myspace users a superior social media experience where they wouldn't be spied on or bombarded with ads:

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3247362

Zuckerberg knew that wouldn't be enough. No one was going to leave Myspace for Facebook and hang out in splendid isolation, smugly re-reading Facebook's world-beating privacy policy while waiting for their dopey friends to wise up and leave Myspace to come and join them.

No: Zuckerberg gave the Myspace refugees a bot, which would accept your Myspace login and password and then impersonate you to Myspace's servers several times per day, scraping all the content waiting for you in your Myspace feed and flowing it into your Facebook feed. You could reply to it there and the bot would push it out to Myspace. You could eat your cake and have it too: use Facebook, but communicate with the people who were still on Myspace.

This is called "adversarial interoperability" and it was once the norm, but the companies that rose to power by "moving fast and breaking things" went on to secure legal protections to prevent anyone from doing unto them as they had done unto their own predecessors:

https://www.eff.org/deeplinks/2019/10/adversarial-interoperability

The harder it is for people to leave a platform, the worse the platform can treat them without paying the penalty of losing users. This is the source of enshittification: when a company can move value from its users and customers to itself without risking their departure, it does.

People stay on bad platforms because the value they provide to one another is greater than the costs the platform extracts from them. That means that when you see people stuck on a very bad platform – like Twitter, Instagram or Facebook – you should infer that what they get there from the people that matter to them is really important to them. They stick to platforms because that's where they meet with people who share their rare disease, because that's where they find the customers or audiences that they rely on to make rent; because that's the only place they can find the people they left behind when they emigrated.

Now, it's entirely possible – likely, even – that legacy social media platforms will grow so terrible that people will leave and jettison those social connections that mean so much to them. This is not a good outcome. Those communities, once shattered, will likely never re-form. There will be permanent, irretrievable losses incurred by their members:

https://pluralistic.net/2023/07/23/when-the-town-square-shatters/

The platforms are sinking ships. We need to evacuate them:

https://pluralistic.net/2024/03/23/evacuate-the-platforms/#let-the-platforms-burn

"If you build it, they will come" is a trap. Technologists and their users who don't understand the pernicious nature of the collective active problem trap themselves. They build obviously superior technical platforms and then gnash their teeth as the rest of the world fails to make the leap.

All too often, users' frustration at the failure of new services to slay the inferior legacy services curdles, and users and designers of new technologies decide that the people who won't join them are somehow themselves defective. It doesn't take long to find a corner of the Fediverse or Bluesky where Facebook and Twitter users are being condemned as morally suspect for staying on zuckermuskian media. They are damned for loving Zuckerberg and Musk, rather than empathized with for loving each other more than they hate the oligarchs who've trapped them. They're condemned as emotionally stunted "attention whores" who hang out on big platforms to get "dopamine" (or some other pseudoscientific reward), which is easier than grappling with the fact that legacy social media pays their bills, and tolerating Zuckerberg or Musk is preferable to getting evicted.

Worst of all, condemning users of legacy technology as moral failures leads you to oppose efforts to get those users out of harm's way and onto modern platforms. Think of the outcry at Meta's Threads taking steps to federate with Mastodon. There are good reasons to worry about this – the best one being that it might allow Meta to (illegally) suck up Mastodon users' data and store and process it. But the majority of the opposition to Threads integration with Mastodon wasn't about Threads' management – it was about Threads' users. It posited a certain kind of moral defective who would use a Zuckerberg-controlled platform in the 2020s and insisted that those people would ruin Mastodon by bringing over their illegitimate social practices.

I've made no secret of where I come down in this debate: the owners of legacy social media are my enemy, but the users of those platforms are my comrades, and I want to help them get shut of legacy social media as quickly and painlessly as possible.

What's more, there's a way to make this happen! The same adversarial interoperability that served Zuckerberg so well when he was draining users off of Myspace could be used today to evacuate all of Meta's platforms. We could use a combination of on-device bridging, scraping and other guerrilla tactics to create "alt clients" that let you interact with people on Mastodon and the legacy platforms in one context, so that you can leave the bad services but keep the good people in your life.

The major barrier to this isn't technological. Despite the boasts of these companies to world-beating engineering prowess, the reality is that people (often teenagers) keep successfully finding and exploiting vulnerabilities in the "impregnable" platforms, in order to build successful alt clients:

https://pluralistic.net/2023/12/07/blue-bubbles-for-all/#never-underestimate-the-determination-of-a-kid-who-is-time-rich-and-cash-poor

The thing that eventually sees off these alt clients isn't Big Tech's technical countermeasures – it's legal risk. A global system of "anticircumvention" laws makes the kinds of basic reverse-engineering associated with building using adversarial interoperability radioactively illegal. These laws didn't appear out of thin air, either: the US Trade Representative pressured all of America's trading partners into passing them:

https://pluralistic.net/2024/11/15/radical-extremists/#sex-pest

Which brings me back to crises precipitating change. Trump has staged an unscheduled, sudden, midair disassembly of the global system of trade, whacking tariffs on every country in the world, even in defiance of the Supreme Court:

https://www.bbc.co.uk/news/articles/cd6zn3ly22yo

Ironically, this has only helped make the case for adversarial interoperability. Trump is using tech companies to attack his geopolitical rivals, ordering Microsoft to shut down both the International Criminal Court and a Brazilian high court in retaliation for their pursuit of the criminal dictators Benjamin Netanyahu and Jair Bolsonaro. This means that Trump has violated the quid pro quo deal for keeping anticircumvention law on your statute books, and he has made the case for killing anticircumvention as quickly as possible in order to escape American tech platforms before they are weaponized against you:

https://pluralistic.net/2026/01/29/post-american-canada/#ottawa

I've been talking about this for more than a year now, and I must say, the reception has been better than I dared dream. I think that – for the first time in my adult life – we are on the verge of creating a new, good, billionaire-proof internet:

https://pluralistic.net/2026/01/15/how-the-light-gets-in/

But there's one objection that keeps coming up: "What if this makes Trump mad?" Or, more specifically, "What if this makes Trump more mad, so instead of hitting us with a 10% tariff, it's a 1,000% tariff?

This came up earlier this week, when I gave a remote keynote for the Fedimtl conference, and an audience member said that he thought we should just focus on building good new platforms, rather than risking Trump's ire. In my response, I recited the arguments I've raised in this piece.

But yesterday, I saw a news item that made me realize there was one more argument I should have made, but missed. It was a Reuters story about Trump ordering American diplomats to fight against "data sovereignty" policies around the world:

https://www.reuters.com/sustainability/boards-policy-regulation/us-orders-diplomats-fight-data-sovereignty-initiatives-2026-02-25/

The news comes from a leaked diplomatic cable, and it's a reminder that Trump's goal is to maintain American dominance of the world's technology and to prevent the formation of a post-American internet altogether. Worrying that Trump will hit you with more tariffs if you legalize jailbreaking assumes that the thing that would upset Trump is that you broke the rules.

That's not what makes Trump angry.

What makes Trump angry is losing.

Say you focus exclusively on building superior platforms. Say by some miracle that everyone you care about somehow overcomes the collective action problems and high switching costs and leaves behind US Big Tech services and comes to your new, federated, cleantech, post-American alternative.

Do you think that Trump will observe this collapse in the fortunes of the most important corporations in his coalition and shrug and say, "Well, I guess I lost fair and square; better luck next time?"

Hell, no. We already know what Trump does when his corporate allies lose to a superior foreign rival – Trump steals the rival's service and gives it to one of his cronies. That's literally what he did last month, to Tiktok:

https://www.democracynow.org/2026/1/23/headlines/larry_ellisons_oracle_part_of_new_deal_to_own_us_version_of_tiktok

The fear of harsh retaliation for any country that dares to be a Disenshittification Nation is based on the premise that Trump is motivated by a commitment to fairness. He's not: Trump is motivated by a desire to dominate. Anything that threatens the dominance of the companies that take his orders is fair game, and he will retaliate in any way he can.

Pluralistic: The whole economy pays the Amazon tax (25 Feb 2026)


Today's links


A giant pile of money bags; climbing out of it is the bear from the California state flag. The background is an Amazon box, with the smile logo pointing in the opposite direction to the bear's motion.

The whole economy pays the Amazon tax (permalink)

Selling on Amazon is a tough business. Sure, you can reach a lot of customers, but this comes at a very high price: the junk fees that Amazon extracts from its sellers amount to 50-60% of the price you pay.

That's a hell of a lot of money to hand over to a middleman, but it's not like vendors have much choice. The vast majority of America's affluent households are Prime subscribers (depending on how you define "affluent household" it's north of 90%). Prime households prepay for a year's worth of shipping, so it's only natural that they start their shopping on Amazon, where they've already paid the delivery costs. And because Amazon reliably meets or beats the prices you'd pay elsewhere, Prime subscribers who find a product on Amazon overwhelmingly stop their shopping at Amazon, too.

At this point you might be thinking a couple things:

I. Why not try to sell the non-affluent households, who are far less likely to subscribe to Prime? and

II. If Amazon has the lowest prices, what's the problem if everyone shops there?

The answers to these two questions are intimately related, as it happens.

Let's start with selling to non-affluent households – basically, the bottom 90% of American earners. The problem here is that everyone who isn't in that top 10% is pretty goddamned broke. It's not just decades of wage stagnation and hyperinflation in health, housing and education costs. It's also that every economic crisis of this century has resulted in a "K-shaped" recovery, in which "economic recovery" means that rich people are doing fine, while everyone else is worse off than they were before the crisis.

For decades, America papered over the K-shaped hole in its economy with debt. First it was credit cards. Then it was gimmicky mortgages – home equity lines of credit, second mortgages and reverse mortgages. Then it was payday lenders. Then it was "buy-now/pay-later" services that let you buy lunch at Chipotle on an installment plan that is nominally interest-free, but is designed to trap the unwary and unlucky with massive penalties if you miss a single payment.

This produced a median American who isn't just cash-poor – they are cash-negative, drowning in debt. And – with the exception of a brief Biden intercession – every presidential administration of the 21st century has enacted policies that favor creditors over debtors. Bankruptcy is harder to declare, and creditors can hit you with effectively unlimited penalties and confiscation of your property and wages once your cash is gone. Trump has erased all the small mercies of the Biden years – for example, he just forced 8,000,000 student borrowers back into repayment:

https://prospect.org/2025/12/16/gop-forcing-eight-million-student-loan-borrowers-into-repayment/

The average American worker has $955 saved for retirement:

https://finance.yahoo.com/news/955-saved-for-retirement-millions-are-in-that-boat-150003868.html

There's plenty to worry about in a K-shaped economy – big things like "political instability" and "cultural chaos" (the fact that most people are broke has a lot to do with the surging fortunes of gambling platforms). But from a seller's perspective, the most important impact of the K-shaped economy is that only rich people buy stuff. Selling to the bottom 90% is a losing proposition because they're increasingly too broke to buy anything:

https://pluralistic.net/2025/12/16/k-shaped-recovery/#disenshittification-nations

Combine the fact that the richest 10% of Americans all start their shopping on Amazon with the fact that no one else can afford to buy anything, and it's easy to see why merchants would stay on Amazon, even when junk fees hit 60%.

Which brings us to the second question: if Amazon has the best prices, what's the problem with everyone shopping there?

The answer is to be found in the California Attorney General's price-fixing lawsuit against Amazon:

https://oag.ca.gov/news/press-releases/attorney-general-bonta-exposes-amazon-price-fixing-scheme-driving-costs

The suit's been running for a long time, but the AG's office just celebrated a milestone – they've finished analyzing the internal memos they forced Amazon to disgorge through civil law's "discovery" process. These internal docs verify an open – and very dirty – secret about Amazon: the company uses its power to push up prices across the entire economy.

Here's how that works: sellers have to sell on Amazon, and that means they're losing $0.50-$0.60 on every dollar. The obvious way to handle this is by raising prices. But Amazon knows that its power comes from offering buyers prices that are as low or lower than the prices at all its competitors.

Amazon could ban its sellers from raising prices, but if they did that, they'd have to accept a smaller share of every sale (otherwise most of their sellers would go broke from selling at a loss on Amazon). So instead, Amazon imposes a business practice called "most favored nation" (MFN) pricing on its sellers.

Under an MFN arrangement, sellers are allowed to raise their prices on Amazon, but when they do, they must raise their prices everywhere else, too: at Walmart, at Target, at mom and pop indie stores, and at their own factory outlet store. Remember: Amazon doesn't have to have low prices to win, it just needs to have the same prices as everyone else. So long as prices rise throughout the economy, Amazon is fine, and it can continue to hike its junk fees on sellers, knowing that they will pay those fees by raising prices on Amazon and everywhere else their products are sold.

Like I say, this isn't really a secret. MFN terms were the basis of DC Attorney General Ken Racine's case against Amazon, five years ago:

https://pluralistic.net/2021/06/01/you-are-here/#prime-facie

Amazon's not the only company that does this. Under the Biden administration, the FTC brought a lawsuit against Pepsi because Pepsi and Walmart had rigged the market so that when Walmart raised its prices, Pepsi would force everyone else who carried Pepsi products to raise their prices even more. Walmart still had the lowest prices, but everything everywhere got more expensive, both at Walmart and everywhere else:

https://www.thebignewsletter.com/p/secret-documents-show-pepsi-and-walmart

Trump's FTC dropped the Pepsi/Walmart case, and Amazon wriggled out of the DC case, but the California AG's office has a lot more resources than DC can muster. This is a timely reminder that America's antitrust laws can be enforced at the state level as well as by the federal authorities. Trump might be happy to let Amazon steal from Americans so long as Jeff Bezos neuters the Washington Post, writes a check for $1m to sit on the inaugural dais, and makes a garbage movie about Melania; but that doesn't stop California AG Rob Bonta from going after Amazon for ripping off Californians (and, in so doing, develop the evidentiary record and precedent that will allow every other state AG to go after Amazon).

The fact that Amazon's monopoly lets it control prices across the economy highlights the futility of trying to fix the Amazon problem by shopping elsewhere. A "boycott" isn't you shopping really hard, it's an organized movement with articulated demands, a theory of change, and a backbone of solidarity. "Conscious consumption" is a dead-end:

https://jacobin.com/2026/02/individual-boycotts-collective-action-ice/

Obviously, Californians have more to worry about than getting ripped off by Amazon (like getting murdered or kidnapped by ICE agents who want to send us all to a slave labor camp in El Salvador), but the billions that Amazon steals from American buyers and sellers are the source of the millions that Bezos uses to support Trump's fascist takeover of America. Without billionaires who would happily support concentration camps in their back yards if it means saving a dollar on their taxes, fascism would still be a fringe movement.

That's why, when we hold new Nuremberg trials for Trump and his collaborators, we should also unwind every merger that was approved under Trump:

https://pluralistic.net/2026/02/10/miller-in-the-dock/#denazification

The material support for Trump's ideology of hate, violence and terror comes from Trump's program of unregulated corporate banditry. A promise to claw back every stolen dime might cool the ardor of Trump's corporate supporters, and even if it doesn't, zeroing out their bank-balances after Trump is gone will be an important lesson for future would-be billionaire collaborators.

Notes on clarifying man pages

Hello! After spending some time working on the Git man pages last year, I’ve been thinking a little more about what makes a good man page.

I’ve spent a lot of time writing cheat sheets for tools (tcpdump, git, dig, etc) which have a man page as their primary documentation. This is because I often find the man pages hard to navigate to get the information I want.

Lately I’ve wondering – could the man page itself have an amazing cheat sheet in it? What might make a man page easier to use? I’m still very early in thinking about this but I wanted to write down some quick notes.

I asked some people on Mastodon for their favourite man pages, and here are some examples of interesting things I saw on those man pages.

an OPTIONS SUMMARY

If you’ve read a lot of man pages you’ve probably seen something like this in the SYNOPSIS: once you’re listing almost the entire alphabet, it’s hard

ls [-@ABCFGHILOPRSTUWabcdefghiklmnopqrstuvwxy1%,]

grep [-abcdDEFGHhIiJLlMmnOopqRSsUVvwXxZz]

The rsync man page has a solution I’ve never seen before: it keeps its SYNOPSIS very terse, like this:

 Local:
     rsync [OPTION...] SRC... [DEST]

and then has an “OPTIONS SUMMARY” section with a 1-line summary of each option, like this:

--verbose, -v            increase verbosity
--info=FLAGS             fine-grained informational verbosity
--debug=FLAGS            fine-grained debug verbosity
--stderr=e|a|c           change stderr output mode (default: errors)
--quiet, -q              suppress non-error messages
--no-motd                suppress daemon-mode MOTD

Then later there’s the usual OPTIONS section with a full description of each option.

an OPTIONS section organized by category

The strace man page organizes its options by category (like “General”, “Startup”, “Tracing”, and “Filtering”, “Output Format”) instead of alphabetically.

As an experiment I tried to take the grep man page and make an “OPTIONS SUMMARY” section grouped by category, you can see the results here. I’m not sure what I think of the results but it was a fun exercise. When I was writing that I was thinking about how I can never remember the name of the -l grep option. It always takes me what feels like forever to find it in the man page and I was trying to think of what structure would make it easier for me to find. Maybe categories?

a cheat sheet

A couple of people pointed me to the suite of Perl man pages (perlfunc, perlre, etc), and one thing I noticed was man perlcheat, which has cheat sheet sections like this:

 SYNTAX
 foreach (LIST) { }     for (a;b;c) { }
 while   (e) { }        until (e)   { }
 if      (e) { } elsif (e) { } else { }
 unless  (e) { } elsif (e) { } else { }
 given   (e) { when (e) {} default {} }

I think this is so cool and it makes me wonder if there are other ways to write condensed ASCII 80-character-wide cheat sheets for use in man pages.

A common comment was something to the effect of “I like any man page that has examples”. Someone mentioned the OpenBSD man pages, and the openbsd tail man page has examples of the exact 2 ways I use tail at the end.

I think I’ve most often seen the EXAMPLES section at the end of the man page, but some man pages (like the rsync man page from earlier) start with the examples. When I was working on the git-add and git rebase man pages I put a short example at the beginning.

This isn’t a property of the man page itself, but one issue with man pages in the terminal is it’s hard to know what sections the man page has.

When working on the Git man pages, one thing Marie and I did was to add a table of contents to the sidebar of the HTML versions of the man pages hosted on the Git site.

I’d also like to add more hyperlinks to the HTML versions of the Git man pages at some point, so that you can click on “INCOMPATIBLE OPTIONS” to get to that section. It’s very easy to add links like this in the Git project since Git’s man pages are generated with AsciiDoc.

I think adding a table of contents and adding internal hyperlinks is kind of a nice middle ground where we can make some improvements to the man page format (in the HTML version of the man page at least) without maintaining a totally different form of documentation. Though for this to work you do need to set up a toolchain like Git’s AsciiDoc system.

It would be amazing if there were some kind of universal system to make it easy to look up a specific option in a man page (“what does -a do?”). The best trick I know is use the man pager to search for something like ^ *-a but I never remember to do it and instead just end up going through every instance of -a in the man page until I find what I’m looking for.

examples for every option

The curl man page has examples for every option, and there’s also a table of contents on the HTML version so you can more easily jump to the option you’re interested in.

For instance the example for --cert makes it easy to see that you likely also want to pass the --key option, like this:

  curl --cert certfile --key keyfile https://example.com

The way they implement this is that there’s [one file for each option](https://github.com/curl/curl/blob/dc08922a61efe546b318daf964514ffbf41583 25/docs/cmdline-opts/append.md) and there’s an “Example” field in that file.

formatting data in a table

Quite a few people said that man ascii was their favourite man page, which looks like this:

 Oct   Dec   Hex   Char                     
 ───────────────────────────────────────────
 000   0     00    NUL '\0' (null character)
 001   1     01    SOH (start of heading)   
 002   2     02    STX (start of text)      
 003   3     03    ETX (end of text)        
 004   4     04    EOT (end of transmission)
 005   5     05    ENQ (enquiry)            
 006   6     06    ACK (acknowledge)        
 007   7     07    BEL '\a' (bell)          
 010   8     08    BS  '\b' (backspace)     
 011   9     09    HT  '\t' (horizontal tab)
 012   10    0A    LF  '\n' (new line)

Obviously man ascii is an unusual man page but I think what’s cool about this man page (other than the fact that it’s always useful to have an ASCII reference) is it’s very easy to scan to find the information you need because of the table format. It makes me wonder if there are more opportunities to display information in a “table” in a man page to make it easier to scan.

the GNU approach

When I talk about man pages it often comes up that the GNU coreutils man pages (for example man tail) don’t have examples, unlike the OpenBSD man pages, which do have examples.

I’m not going to get into this too much because it seems like a fairly political topic and I definitely can’t do it justice here, but here are some things I believe to be true:

  • The GNU project prefers to maintain documentation in “info” manuals instead of man pages. This page says “the man pages are no longer being maintained”.
  • There are 3 ways to read “info” manuals: their HTML version, in Emacs, or with a standalone info tool. I’ve heard from some Emacs users that they like the Emacs info browser. I don’t think I’ve ever talked to anyone who uses the standalone info tool.
  • The info manual entry for tail is linked at the bottom of the man page, and it does have examples
  • The FSF used to sell print books of the GNU software manuals (and maybe they still do sometimes?)

After a certain level of complexity a man page gets really hard to navigate: while I’ve never used the coreutils info manual and probably won’t, I would almost certainly prefer to use the GNU Bash reference manual or the The GNU C Library Reference Manual via their HTML documentation rather than through a man page.

a few more man-page-adjacent things

Here are some tools I think are interesting:

  • The fish shell comes with a Python script to automatically generate tab completions from man pages
  • tldr.sh is a community maintained database of examples, for example you can run it as tldr grep. Lots of people have told me they find it useful.
  • the Dash Mac docs browser has a nice man page viewer in it. I still use the terminal man page viewer but I like that it includes a table of contents, it looks like this:

it’s interesting to think about a constrained format

Man pages are such a constrained format and it’s fun to think about what you can do with such limited formatting options.

Even though I’m very into writing I’ve always had a bad habit of never reading documentation and so it’s a little bit hard for me to think about what I actually find useful in man pages, I’m not sure whether I think most of the things in this post would improve my experience or not. (Except for examples, I LOVE examples)

So I’d be interested to hear about other man pages that you think are well designed and what you like about them, the comments section is here.

Read "No, AI Written Romance Novels Are Not Inevitable"
Read:
“No, AI Written Romance Novels Are Not Inevitable”.
Gita Jackson in Aftermath. Published .
Even according to the Times’ own reporting, readers do not seem to like AI romance novels. One of the two AI critical sources quoted in the article said that she would never knowingly pick up a book written by AI. Another, an author whose work had been scraped by Anthropic to train their AI model, pointed out that flooding the zone with slop makes it much harder for real human authors to be discovered by readers.  What I found most curious was Coral Hart’s reasoning for using a pseudonym in the article. Coral Hart is a retired pen name and the source would not give any of her current pen names “because she still uses her real name for some publishing and coaching projects. She fears that revealing her A.I. use would damage her business for that work.” Huh! That’s weird!

Sam Bankman-Fried has just filed a pro se motion for a new trial, via his mother

February 5, 2026 To Whom It May Concern: Enclosed piease find a pro se motion for a new trial under Rule 33 of the Fed. R. Crim. Proc. On behalf of Samuel Bankman-Fried, along with a supporting Memorandum of Law and a Declaration in support of the motion from Daniel Chapsky. Although Mr. Bankman-Fried is proceeding pro se, because he is currently incarcerated he has authorized me to file this on his behalf. If you have any questions concerning this motion or the supporting papers, please address them to me. My contact information is below. Barbara H. Fried Saunders Professor of Law, Emerita Stanford Law School

His motion mainly argues that two former FTX employees who didn't testify (Daniel Chapsky and Ryan Salame) would have undercut prosecutors' narrative, but were threatened out of testifying. He also claims Nishad Singh was coerced by prosecutors into changing his testimony.

It also repeats his longstanding argument that the funds were never missing and that FTX was never insolvent. (Judge Kaplan got a bit sick of this argument during trial, pointing out that repayment doesn't negate fraud).

The judge was quick to rule:

And finally he demands Judge Kaplan recuse himself, arguing he showed "extreme prejudice". Both that argument and his "no actual loss" theory are already being litigated in his pending appeal before the Second Circuit, which I wrote about here.

Hello! One of my favourite things is starting to learn an Old Boring Technology that I’ve never tried before but that has been around for 20+ years. It feels really good when every problem I’m ever going to have has been solved already 1000 times and I can just get stuff done easily.

I’ve thought it would be cool to learn a popular web framework like Rails or Django or Laravel for a long time, but I’d never really managed to make it happen. But I started learning Django to make a website a few months back, I’ve been liking it so far, and here are a few quick notes!

less magic than Rails

I spent some time trying to learn Rails in 2020, and while it was cool and I really wanted to like Rails (the Ruby community is great!), I found that if I left my Rails project alone for months, when I came back to it it was hard for me to remember how to get anything done because (for example) if it says resources :topics in your routes.rb, on its own that doesn’t tell you where the topics routes are configured, you need to remember or look up the convention.

Being able to abandon a project for months or years and then come back to it is really important to me (that’s how all my projects work!), and Django feels easier to me because things are more explicit.

In my small Django project it feels like I just have 5 main files (other than the settings files): urls.py, models.py, views.py, admin.py, and tests.py, and if I want to know where something else is (like an HTML template) is then it’s usually explicitly referenced from one of those files.

a built-in admin

For this project I wanted to have an admin interface to manually edit or view some of the data in the database. Django has a really nice built-in admin interface, and I can customize it with just a little bit of code.

For example, here’s part of one of my admin classes, which sets up which fields to display in the “list” view, which field to search on, and how to order them by default.

@admin.register(Zine)
class ZineAdmin(admin.ModelAdmin):
    list_display = ["name", "publication_date", "free", "slug", "image_preview"]
    search_fields = ["name", "slug"]
    readonly_fields = ["image_preview"]
    ordering = ["-publication_date"]

it’s fun to have an ORM

In the past my attitude has been “ORMs? Who needs them? I can just write my own SQL queries!”. I’ve been enjoying Django’s ORM so far though, and I think it’s cool how Django uses __ to represent a JOIN, like this:

Zine.objects
    .exclude(product__order__email_hash=email_hash)

This query involves 5 tables: zines, zine_products, products, order_products, and orders. To make this work I just had to tell Django that there’s a ManyToManyField relating “orders” and “products”, and another ManyToManyField relating “zines”, and “products”, so that it knows how to connect zines, orders, products.

I definitely could write that query, but writing product__order__email_hash is a lot less typing, it feels a lot easier to read, and honestly I think it would take me a little while to figure out how to construct the query (which needs to do a few other things than just those joins).

I have zero concern about the performance of my ORM-generated queries so I’m pretty excited about ORMs for now, though I’m sure I’ll find things to be frustrated with eventually.

automatic migrations!

The other great thing about the ORM is migrations!

If I add, delete, or change a field in models.py, Django will automatically generate a migration script like migrations/0006_delete_imageblob.py.

I assume that I could edit those scripts if I wanted, but so far I’ve just been running the generated scripts with no change and it’s been going great. It really feels like magic.

I’m realizing that being able to do migrations easily is important for me right now because I’m changing my data model fairly often as I figure out how I want it to work.

I like the docs

I had a bad habit of never reading the documentation but I’ve been really enjoying the parts of Django’s docs that I’ve read so far. This isn’t by accident: Jacob Kaplan-Moss has a talk from PyCon 2011 on Django’s documentation culture.

For example the intro to models lists the most important common fields you might want to set when using the ORM.

using sqlite

After having a bad experience trying to operate Postgres and not being able to understand what was going on, I decided to run all of my small websites with SQLite instead. It’s been going way better, and I love being able to backup by just doing a VACUUM INTO and then copying the resulting single file.

I’ve been following these instructions for using SQLite with Django in production.

I think it should be fine because I’m expecting the site to have a few hundred writes per day at most, much less than Mess with DNS which has a lot more of writes and has been working well (though the writes are split across 3 different SQLite databases).

built in email (and more)

Django seems to be very “batteries-included”, which I love – if I want CSRF protection, or a Content-Security-Policy, or I want to send email, it’s all in there!

For example, I wanted to save the emails Django sends to a file in dev mode (so that it didn’t send real email to real people), which was just a little bit of configuration.

I just put this settings/dev.py:

EMAIL_BACKEND = "django.core.mail.backends.filebased.EmailBackend"
EMAIL_FILE_PATH = BASE_DIR / "emails"

and then set up the production email like this in settings/production.py

EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp.whatever.com"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = "xxxx"
EMAIL_HOST_PASSWORD = os.getenv('EMAIL_API_KEY')

That made me feel like if I want some other basic website feature, there’s likely to be an easy way to do it built into Django already.

the settings file still feels like a lot

I’m still a bit intimidated by the settings.py file: Django’s settings system works by setting a bunch of global variables in a file, and I feel a bit stressed about… what if I make a typo in the name of one of those variables? How will I know? What if I type WSGI_APPLICATOIN = "config.wsgi.application" instead of WSGI_APPLICATION?

I guess I’ve gotten used to having a Python language server tell me when I’ve made a typo and so now it feels a bit disorienting when I can’t rely on the language server support.

that’s all for now!

I haven’t really successfully used an actual web framework for a project before (right now almost all of my websites are either a single Go binary or static sites), so I’m interested in seeing how it goes!

There’s still lots for me to learn about, I still haven’t really gotten into Django’s form validation tooling or authentication systems.

Thanks to Marco Rogers for convincing me to give ORMs a chance.

(we’re still experimenting with the comments-on-Mastodon system! Here are the comments on Mastodon! tell me your favourite Django feature!)

A data model for Git (and other docs updates)

Hello! This past fall, I decided to take some time to work on Git’s documentation. I’ve been thinking about working on open source docs for a long time – usually if I think the documentation for something could be improved, I’ll write a blog post or a zine or something. But this time I wondered: could I instead make a few improvements to the official documentation?

So Marie and I made a few changes to the Git documentation!

a data model for Git

After a while working on the documentation, we noticed that Git uses the terms “object”, “reference”, or “index” in its documentation a lot, but that it didn’t have a great explanation of what those terms mean or how they relate to other core concepts like “commit” and “branch”. So we wrote a new “data model” document!

You can read the data model here for now. I assume at some point (after the next release?) it’ll also be on the Git website.

I’m excited about this because understanding how Git organizes its commit and branch data has really helped me reason about how Git works over the years, and I think it’s important to have a short (1600 words!) version of the data model that’s accurate.

The “accurate” part turned out to not be that easy: I knew the basics of how Git’s data model worked, but during the review process I learned some new details and had to make quite a few changes (for example how merge conflicts are stored in the staging area).

updates to git push, git pull, and more

I also worked on updating the introduction to some of Git’s core man pages. I quickly realized that “just try to improve it according to my best judgement” was not going to work: why should the maintainers believe me that my version is better?

I’ve seen a problem a lot when discussing open source documentation changes where 2 expert users of the software argue about whether an explanation is clear or not (“I think X would be a good way to explain it! Well, I think Y would be better!”)

I don’t think this is very productive (expert users of a piece of software are notoriously bad at being able to tell if an explanation will be clear to non-experts), so I needed to find a way to identify problems with the man pages that was a little more evidence-based.

getting test readers to identify problems

I asked for test readers on Mastodon to read the current version of documentation and tell me what they find confusing or what questions they have. About 80 test readers left comments, and I learned so much!

People left a huge amount of great feedback, for example:

  • terminology they didn’t understand (what’s a pathspec? what does “reference” mean? does “upstream” have a specific meaning in Git?)
  • specific confusing sentences
  • suggestions of things things to add (“I do X all the time, I think it should be included here”)
  • inconsistencies (“here it implies X is the default, but elsewhere it implies Y is the default”)

Most of the test readers had been using Git for at least 5-10 years, which I think worked well – if a group of test readers who have been using Git regularly for 5+ years find a sentence or term impossible to understand, it makes it easy to argue that the documentation should be updated to make it clearer.

I thought this “get users of the software to comment on the existing documentation and then fix the problems they find” pattern worked really well and I’m excited about potentially trying it again in the future.

the man page changes

We ended updating these 4 man pages:

The git push and git pull changes were the most interesting to me: in addition to updating the intro to those pages, we also ended up writing:

Making those changes really gave me an appreciation for how much work it is to maintain open source documentation: it’s not easy to write things that are both clear and true, and sometimes we had to make compromises, for example the sentence “git push may fail if you haven’t set an upstream for the current branch, depending on what push.default is set to.” is a little vague, but the exact details of what “depending” means are really complicated and untangling that is a big project.

on the process for contributing to Git

It took me a while to understand Git’s development process. I’m not going to try to describe it here (that could be a whole other post!), but a few quick notes:

  • Git has a Discord server with a “my first contribution” channel for help with getting started contributing. I found people to be very welcoming on the Discord.
  • I used GitGitGadget to make all of my contributions. This meant that I could make a GitHub pull request (a workflow I’m comfortable with) and GitGitGadget would convert my PRs into the system the Git developers use (emails with patches attached). GitGitGadget worked great and I was very grateful to not have to learn how to send patches by email with Git.
  • Otherwise I used my normal email client (Fastmail’s web interface) to reply to emails, wrapping my text to 80 character lines since that’s the mailing list norm.

I also found the mailing list archives on lore.kernel.org hard to navigate, so I hacked together my own git list viewer to make it easier to read the long mailing list threads.

Many people helped me navigate the contribution process and review the changes: thanks to Emily Shaffer, Johannes Schindelin (the author of GitGitGadget), Patrick Steinhardt, Ben Knoble, Junio Hamano, and more.

Client Registration and Enterprise Management in the November 2025 MCP Authorization Spec

The new MCP authorization spec is here! Today marks the one-year anniversary of the Model Context Protocol, and with it, the launch of the new 2025-11-25 specification.

I’ve been helping out with the authorization part of the spec for the last several months, working to make sure we aren't just shipping something that works for hobbyists, but something that even scales to the enterprise. If you’ve been following my posts like Enterprise-Ready MCP or Let's Fix OAuth in MCP, you know this has been a bit of a journey over the past year.

The new spec just dropped, and while there are a ton of great updates across the board, far more than I can get in to in this blog post, there are two changes in the authorization layer that I am most excited about. They fundamentally change how clients identify themselves and how enterprises manage access to AI-enabled apps.

Client ID Metadata Documents (CIMD)

If you’ve ever tried to work with an open ecosystem of OAuth clients and servers, you know the "Client Registration" problem. In traditional OAuth, you go to a developer portal, register your app, and get a client_id and client_secret. That works great when there is one central server (like Google or GitHub) and many clients that want to use that server.

It breaks down completely in an open ecosystem like MCP, where we have many clients talking to many servers. You can't expect a developer of a new AI Agent to manually register with every single one of the 2,000 MCP servers in the MCP server registry. Plus, when a new MCP server launches, that server wouldn't be able to ask every client developer to register either.

Until now, the answer for MCP was Dynamic Client Registration (DCR). But as implementation experiences has shown us over the last several months, DCR introduces a massive amount of complexity and risk for both sides.

For Authorization Servers, DCR endpoints are a headache. They require public-facing APIs that need strict rate limiting to prevent abuse, and they lead to unbounded database growth as thousands of random clients register themselves. The number of client registrations will only ever increase, so the authorization server is likely to implement some sort of "cleanup" mechanism to delete old client registrations. The problem is there is no clear definition of what an "old" client is.  And if a dynamically registered client is deleted, the client doesn't know about it, and the user is often stuck with no way to recover. Because of the security implications of an endpoint like this, DCR has also been a massive barrier to enterprise adoption of MCP.

For Clients, it’s just as bad. They have to manage the lifecycle of their client credentials on top of the actual access tokens, and there is no standardized way to check if the client registration is still valid. This frequently leads to sloppy implementations where clients simply register a brand new client_id every single time a user logs in, further increasing the number of client registrations at the authorization server. This isn't a theoretical problem, this is also how Mastodon has worked for the last several years, and has some GitHub issue threads describing the challenges it creates.

The new MCP spec solves this by adopting Client ID Metadata Documents.

The OAuth Working Group adopted the Client ID Metadata Document spec in October after about a year of discussion, so it's still relatively new. But seeing it land as the default mechanism in MCP is huge. Instead of the client registering with each authorization server, the client establishes its own identity with a URL it controls and uses the URL to identify itself during an OAuth flow.

When the client starts an OAuth request to the MCP authorization server, it says, "Hi, I'm https://example-app.com/client.json." The server fetches the JSON document at that URL and finds the client's metadata (logo, name, redirect URIs) and proceeds on as usual.

This creates a decentralized trust model based on DNS. If you trust example.com, you trust the client. It removes the registration friction entirely while keeping the security guarantees we need. It’s the same pattern we’ve used in IndieAuth for over a decade, and it fits MCP perfectly.

There are definitely some new considerations and risks this brings, so it's worth diving into the details about Client ID Metadata Documents in the MCP spec as well as the IETF spec. For example, if you're building an MCP client that is running on a web server, you can actually manage private keys and publish the public keys in your metadata document, enabling strong client authentication. And like Dynamic Client Registration, there are still limitations for how desktop clients can leverage this, which can hopefully be solved by a future extension. I talked more about this during a hugely popular session at the Internet Identity Workshop in October, you can find the slides here.

You can try out this new flow today in VSCode, the first MCP client to ship support for CIMD even before it was officially in the spec. You can also learn more and test it out at the excellent website the folks at Stytch created: client.dev.

Enterprise-Managed Authorization (Cross App Access)

This is the big one for anyone asking, "Is MCP safe to use in the enterprise?"

Until now, when an AI agent connected to an MCP server, the connection was established directly between the MCP client and server. For example if you are using ChatGPT to connect to the Asana MCP server, ChatGPT would start an OAuth flow to Asana. But if your Asana account is actually connected to an enterprise IdP like Okta, Okta would only see that you're logging in to Asana, and wouldn't be aware of the connection established between ChatGPT and Asana. This means today there are a huge number of what are effectively unmanaged connections between MCP clients and servers in the enterprise. Enterprise IT admins hate this because it creates "Shadow IT" connections that bypass enterprise policy.

The new MCP spec incorporates Cross App Access (XAA) as the authorization extension "Enterprise-Managed Authorization".

This builds on the work I discussed in Enterprise-Ready MCP leveraging the Identity Assertion Authorization Grant. The flow puts the enterprise Identity Provider (IdP) back in the driver's seat.

Here is how it works:

  1. Single Sign-On: First you log into an MCP Client (like Claude or an IDE) using your corporate SSO, the client gets an ID token.

  2. Token Exchange: Instead of the client starting an OAuth flow to ask the user to manually approve access to a downstream tool (like an Asana MCP server), the client takes that ID token back to the Enterprise IdP to ask for access.

  3. Policy Check: The IdP checks corporate policy. "Is Engineering allowed to use Claude to access Asana?" If the policy passes, the IdP issues a temporary token (ID-JAG) that the client can take to the MCP authorization server.

  4. Access Token Request: The MCP client takes the ID-JAG to the MCP authorization server saying "hey this IdP says you can issue me an access token for this user". The authorization server validates the ID-JAG the same way it would have validated an ID Token (remember this app is also set up for SSO to the same corporate IdP), and issues an access token.

This happens entirely behind the scenes without user interaction. The user doesn't get bombarded with consent screens, and the enterprise admin gets full visibility and revocability. If you want to shut down AI access to a specific internal tool, you do it in one place: your IdP.

Further Reading

There is a lot more in the full spec update, but these two pieces—CIMD for scalable client identity and Cross App Access for enterprise security—are the two I am most excited about. They take MCP to the next level by solving the biggest challenges that were preventing scalable adoption of MCP in the enterprise.

You can read more about the MCP authorization spec update in Den's excellent post, and more about all the updates to the MCP spec in the official announcement post.

Recurring Events for Meetable

In October, I launched an instance of Meetable for the MCP Community. They've been using it to post working group meetings as well as in-person community events. In just 2 months it already has 41 events listed!

One of the aspects of opening up the software to a new community is stress testing some of the design decisions. An early design decision was intentionally to not support recurring events. For a community calendar, recurring events are often problematic. Once a recurring event is created for something like a weekly meetup, it's no longer clear whether the event is actually going to happen, which is especially true for virtual events. If an organizer of the event silently drops away from the community, it's very likely they will not go delete the event, and you can end up with stale events on the calendar quickly. It's better to have people explicitly create the event on the calendar so that every event was created with intention. To support this, I made a "Clone Event" button to quickly copy the details from a previous instance, and it even predicts the next date based on how often the event has been happening in the past.

But for the MCP community, which is a bit more formal than a purely community calendar, most of the events on their site are weekly or biweekly working group meetings. I had been hearing quite a bit of feedback that the current process of scheduling out the events manually, even with the "clone event" feature, was too much of a burden. So I set out to design a solution for recurring events to strike a balance between ease of use and hopefully avoiding some of the pitfalls of recurring events.

What I landed on is this:

You can create an "event template" from any existing event on the calendar, and give it a recurrence interval like "Every week on Tuesdays" or "Monthly on the 9th".

recurrence options

(I'll add an option for "Monthly on the second Tuesday" later if this ends up being used enough.)

Once the schedule is created, copies of the event will be created at the chosen interval, but only a few weeks out. For weekly events, 4 weeks in advance will be created, biweekly will get scheduled 8 weeks out, monthly events 4 months out, and yearly events will have only the next year scheduled. Every day a cron job will create future events at the scheduled interval in advance. If the event template is deleted, future scheduled events will also be deleted.

So effectively for organizers there is nothing they need to do after creating the recurring event schedule. My hope is by having it work this way, instead of like recurring events on a typical Google calendar, it strikes a balance between ease of use but avoids orphaned events on the calendar. It still requires an organizer to delete a recurrence, so should only be used for events that truly have a schedule and are unlikely to be cancelled often.

Hopefully this makes Meetable even more useful for different kinds of communities! You can install your own copy of Meetable from the source code on GitHub.

Adding Support for BlueSky to IndieLogin.com

Today I just launched support for BlueSky as a new authentication option in IndieLogin.com!

IndieLogin.com is a developer service that allows users to log in to a website with their domain. It delegates the actual user authentication out to various external services, whether that is an IndieAuth server, GitHub, GitLab, Codeberg, or just an email confirmation code, and now also BlueSky.

This means if you have a custom domain as your BlueSky handle, you can now use it to log in to websites like indieweb.org directly!

bluesky login

Alternatively, you can add a link to your BlueSky handle from your website with a rel="me atproto" attribute, similar to how you would link to your GitHub profile from your website.

<a href="https://example.bsky.social" rel="me atproto">example.bsky.social</a>

Full setup instructions here

This is made possible thanks to BlueSky's support of the new OAuth Client ID Metadata Document specification, which was recently adopted by the OAuth Working Group. This means as the developer of the IndieLogin.com service, I didn't have to register for any BlueSky API keys in order to use the OAuth server! The IndieLogin.com website publishes its own metadata which the BlueSky OAuth server can use to fetch the metadata from. This is the same client metadata that an IndieAuth server will parse as well! Aren't standards fun!

The hardest part about the whole process was probably adding DPoP support. Actually creating the DPoP JWT wasn't that bad but the tricky part was handling the DPoP server nonces sent back. I do wish we had a better solution for that mechanism in DPoP, but I remember the reasoning for doing it this way and I guess we just have to live with it now.

This was a fun exercise in implementing a bunch of the specs I've been working on recently!

Here's the link to the full ATProto OAuth docs for reference.

Notes on switching to Helix from vim

Hello! Earlier this summer I was talking to a friend about how much I love using fish, and how I love that I don’t have to configure it. They said that they feel the same way about the helix text editor, and so I decided to give it a try.

I’ve been using it for 3 months now and here are a few notes.

why helix: language servers

I think what motivated me to try Helix is that I’ve been trying to get a working language server setup (so I can do things like “go to definition”) and getting a setup that feels good in Vim or Neovim just felt like too much work.

After using Vim/Neovim for 20 years, I’ve tried both “build my own custom configuration from scratch” and “use someone else’s pre-buld configuration system” and even though I love Vim I was excited about having things just work without having to work on my configuration at all.

Helix comes with built in language server support, and it feels nice to be able to do things like “rename this symbol” in any language.

the search is great

One of my favourite things about Helix is the search! If I’m searching all the files in my repository for a string, it lets me scroll through the potential matching files and see the full context of the match, like this:

For comparison, here’s what the vim ripgrep plugin I’ve been using looks like:

There’s no context for what else is around that line.

the quick reference is nice

One thing I like about Helix is that when I press g, I get a little help popup telling me places I can go. I really appreciate this because I don’t often use the “go to definition” or “go to reference” feature and I often forget the keyboard shortcut.

some vim -> helix translations

  • Helix doesn’t have marks like ma, 'a, instead I’ve been using Ctrl+O and Ctrl+I to go back (or forward) to the last cursor location
  • I think Helix does have macros, but I’ve been using multiple cursors in every case that I would have previously used a macro. I like multiple cursors a lot more than writing macros all the time. If I want to batch change something in the document, my workflow is to press % (to highlight everything), then s to select (with a regex) the things I want to change, then I can just edit all of them as needed.
  • Helix doesn’t have neovim-style tabs, instead it has a nice buffer switcher (<space>b) I can use to switch to the buffer I want. There’s a pull request here to implement neovim-style tabs. There’s also a setting bufferline="multiple" which can act a bit like tabs with gp, gn for prev/next “tab” and :bc to close a “tab”.

some helix annoyances

Here’s everything that’s annoyed me about Helix so far.

  • I like the way Helix’s :reflow works much less than how vim reflows text with gq. It doesn’t work as well with lists. (github issue)
  • If I’m making a Markdown list, pressing “enter” at the end of a list item won’t continue the list. There’s a partial workaround for bulleted lists but I don’t know one for numbered lists.
  • No persistent undo yet: in vim I could use an undofile so that I could undo changes even after quitting. Helix doesn’t have that feature yet. (github PR)
  • Helix doesn’t autoreload files after they change on disk, I have to run :reload-all (:ra<tab>) to manually reload them. Not a big deal.
  • Sometimes it crashes, maybe every week or so. I think it might be this issue.

The “markdown list” and reflowing issues come up a lot for me because I spend a lot of time editing Markdown lists, but I keep using Helix anyway so I guess they can’t be making me that mad.

switching was easier than I thought

I was worried that relearning 20 years of Vim muscle memory would be really hard.

It turned out to be easier than I expected, I started using Helix on a vacation for a little low-stakes coding project I was doing on the side and after a week or two it didn’t feel so disorienting anymore. I think it might be hard to switch back and forth between Vim and Helix, but I haven’t needed to use Vim recently so I don’t know if that’ll ever become an issue for me.

The first time I tried Helix I tried to force it to use keybindings that were more similar to Vim and that did not work for me. Just learning the “Helix way” was a lot easier.

There are still some things that throw me off: for example w in vim and w in Helix don’t have the same idea of what a “word” is (the Helix one includes the space after the word, the Vim one doesn’t).

using a terminal-based text editor

For many years I’d mostly been using a GUI version of vim/neovim, so switching to actually using an editor in the terminal was a bit of an adjustment.

I ended up deciding on:

  1. Every project gets its own terminal window, and all of the tabs in that window (mostly) have the same working directory
  2. I make my Helix tab the first tab in the terminal window

It works pretty well, I might actually like it better than my previous workflow.

my configuration

I appreciate that my configuration is really simple, compared to my neovim configuration which is hundreds of lines. It’s mostly just 4 keyboard shortcuts.

theme = "solarized_light"
[editor]
# Sync clipboard with system clipboard
default-yank-register = "+"

[keys.normal]
# I didn't like that Ctrl+C was the default "toggle comments" shortcut
"#" = "toggle_comments"

# I didn't feel like learning a different way
# to go to the beginning/end of a line so
# I remapped ^ and $
"^" = "goto_first_nonwhitespace"
"$" = "goto_line_end"

[keys.select]
"^" = "goto_first_nonwhitespace"
"$" = "goto_line_end"

[keys.normal.space]
# I write a lot of text so I need to constantly reflow,
# and missed vim's `gq` shortcut
l = ":reflow"

There’s a separate languages.toml configuration where I set some language preferences, like turning off autoformatting. For example, here’s my Python configuration:

[[language]]
name = "python"
formatter = { command = "black", args = ["--stdin-filename", "%{buffer_name}", "-"] }
language-servers = ["pyright"]
auto-format = false

we’ll see how it goes

Three months is not that long, and it’s possible that I’ll decide to go back to Vim at some point. For example, I wrote a post about switching to nix a while back but after maybe 8 months I switched back to Homebrew (though I’m still using NixOS to manage one little server, and I’m still satisfied with that).

Client ID Metadata Document Adopted by the OAuth Working Group

The IETF OAuth Working Group has adopted the Client ID Metadata Document specification!

This specification defines a mechanism through which an OAuth client can identify itself to authorization servers, without prior dynamic client registration or other existing registration.

Clients identify themselves with their own URL, and host their metadata (name, logo, redirect URL) in a JSON document at that URL. They then use that URL as the client_id to introduce themselves to an authorization server for the first time.

The mechanism of clients identifying themselves as a URL has been in use in IndieAuth for over a decade, and more recently has been adopted by BlueSky for their OAuth API. The recent surge in interest in MCP has further demonstrated the need for this to be a standardized mechanism, and was the main driver in the latest round of discussion for the document! This could replace Dynamic Client Registration in MCP, dramatically simplifying management of clients, as well as enabling servers to limit access to specific clients if they want.

Meetable Release Notes - October 2025

I just released some updates for Meetable, my open source event listing website.

The major new feature is the ability to let users log in with a Discord account. A Meetable instance can be linked to a Discord server to enable any member of the server to log in to the site. You can also restrict who can log in based on Discord "roles", so you can limit who can edit events to only certain Discord members.

One of the first questions I get about Meetable is whether recurring events are supported. My answer has always been "no". In general, it's too easy for recurring events on community calendars go get stale. If an organizer forgets to cancel or just stops showing up, that isn't visible unless someone takes the time to clean up the recurrence. Instead, it's healthier to require each event be created manually. There is a "clone event" feature that makes it easy to copy all the details from a previous event to be able to quickly manually create these sorts of recurring events. In this update, I just added a feature to streamline this even further. The next recurrence is now predicted based on the past interval of the event.

For example, for a biweekly cadence, the following steps happen now:

  • You would create the first instance manually, say for October 1
  • You click "Clone Event" and change the date of the new event to October 15
  • Now when you click "Clone Event" on the October 15 event, it will pre-fill October 29 based on the fact that the October 15 event was created 2 weeks after the event it was cloned from

Currently this only works by counting days, so wouldn't work for things like "first Tuesday of the month" or "the 1st of the month", but I hope this saves some time in the future regardless. If "first Tuesday" or specific days of the month are an important use case for you, let me know and I can try to come up with a solution.

Minor changes/fixes below:

  • Added "Create New Event" to the "Add Event" dropdown menu because it wasn't obvious "Add Event" was clickable.
  • Meeting link no longer appears for cancelled events. (Actually the meeting link only appears for "confirmed" events.)
  • If you add a meeting link but don't set a timezone, a warning message appears on the event.
  • Added a setting to show a message when uploading a photo, you can use this to describe a photo license policy for example.
  • Added a "user profile" page, and if users are configured to fetch profile info from their website, a button to re-fetch the profile info will appear.

San Francisco Billboards - August 2025

Every time I take a Lyft from the San Francisco airport to downtown going up 101, I notice the billboards. The billboards on 101 are always such a good snapshot in time of the current peak of the Silicon Valley hype cycle. I've decided to capture photos of the billboards every time I am there, to see how this changes over time. 

Here's a photo dump from the 101 billboards from August 2025. The theme is clearly AI. Apologies for the slightly blurry photos, these were taken while driving 60mph down the highway, some of them at night.

New zine: The Secret Rules of the Terminal

Hello! After many months of writing deep dive blog posts about the terminal, on Tuesday I released a new zine called “The Secret Rules of the Terminal”!

You can get it for $12 here: https://wizardzines.com/zines/terminal, or get an 15-pack of all my zines here.

Here’s the cover:

the table of contents

Here’s the table of contents:

why the terminal?

I’ve been using the terminal every day for 20 years but even though I’m very confident in the terminal, I’ve always had a bit of an uneasy feeling about it. Usually things work fine, but sometimes something goes wrong and it just feels like investigating it is impossible, or at least like it would open up a huge can of worms.

So I started trying to write down a list of weird problems I’ve run into in terminal and I realized that the terminal has a lot of tiny inconsistencies like:

  • sometimes you can use the arrow keys to move around, but sometimes pressing the arrow keys just prints ^[[D
  • sometimes you can use the mouse to select text, but sometimes you can’t
  • sometimes your commands get saved to a history when you run them, and sometimes they don’t
  • some shells let you use the up arrow to see the previous command, and some don’t

If you use the terminal daily for 10 or 20 years, even if you don’t understand exactly why these things happen, you’ll probably build an intuition for them.

But having an intuition for them isn’t the same as understanding why they happen. When writing this zine I actually had to do a lot of work to figure out exactly what was happening in the terminal to be able to talk about how to reason about it.

the rules aren’t written down anywhere

It turns out that the “rules” for how the terminal works (how do you edit a command you type in? how do you quit a program? how do you fix your colours?) are extremely hard to fully understand, because “the terminal” is actually made of many different pieces of software (your terminal emulator, your operating system, your shell, the core utilities like grep, and every other random terminal program you’ve installed) which are written by different people with different ideas about how things should work.

So I wanted to write something that would explain:

  • how the 4 pieces of the terminal (your shell, terminal emulator, programs, and TTY driver) fit together to make everything work
  • some of the core conventions for how you can expect things in your terminal to work
  • lots of tips and tricks for how to use terminal programs

this zine explains the most useful parts of terminal internals

Terminal internals are a mess. A lot of it is just the way it is because someone made a decision in the 80s and now it’s impossible to change, and honestly I don’t think learning everything about terminal internals is worth it.

But some parts are not that hard to understand and can really make your experience in the terminal better, like:

  • if you understand what your shell is responsible for, you can configure your shell (or use a different one!) to access your history more easily, get great tab completion, and so much more
  • if you understand escape codes, it’s much less scary when cating a binary to stdout messes up your terminal, you can just type reset and move on
  • if you understand how colour works, you can get rid of bad colour contrast in your terminal so you can actually read the text

I learned a surprising amount writing this zine

When I wrote How Git Works, I thought I knew how Git worked, and I was right. But the terminal is different. Even though I feel totally confident in the terminal and even though I’ve used it every day for 20 years, I had a lot of misunderstandings about how the terminal works and (unless you’re the author of tmux or something) I think there’s a good chance you do too.

A few things I learned that are actually useful to me:

  • I understand the structure of the terminal better and so I feel more confident debugging weird terminal stuff that happens to me (I was even able to suggest a small improvement to fish!). Identifying exactly which piece of software is causing a weird thing to happen in my terminal still isn’t easy but I’m a lot better at it now.
  • you can write a shell script to copy to your clipboard over SSH
  • how reset works under the hood (it does the equivalent of stty sane; sleep 1; tput reset) – basically I learned that I don’t ever need to worry about remembering stty sane or tput reset and I can just run reset instead
  • how to look at the invisible escape codes that a program is printing out (run unbuffer program > out; less out)
  • why the builtin REPLs on my Mac like sqlite3 are so annoying to use (they use libedit instead of readline)

blog posts I wrote along the way

As usual these days I wrote a bunch of blog posts about various side quests:

people who helped with this zine

A long time ago I used to write zines mostly by myself but with every project I get more and more help. I met with Marie Claire LeBlanc Flanagan every weekday from September to June to work on this one.

The cover is by Vladimir Kašiković, Lesley Trites did copy editing, Simon Tatham (who wrote PuTTY) did technical review, our Operations Manager Lee did the transcription as well as a million other things, and Jesse Luehrs (who is one of the very few people I know who actually understands the terminal’s cursed inner workings) had so many incredibly helpful conversations with me about what is going on in the terminal.

Here are some links to get the zine again:

As always, you can get either a PDF version to print at home or a print version shipped to your house. The only caveat is print orders will ship in August – I need to wait for orders to come in to get an idea of how many I should print before sending it to the printer.

Using `make` to compile C programs (for non-C-programmers)

I have never been a C programmer but every so often I need to compile a C/C++ program from source. This has been kind of a struggle for me: for a long time, my approach was basically “install the dependencies, run make, if it doesn’t work, either try to find a binary someone has compiled or give up”.

“Hope someone else has compiled it” worked pretty well when I was running Linux but since I’ve been using a Mac for the last couple of years I’ve been running into more situations where I have to actually compile programs myself.

So let’s talk about what you might have to do to compile a C program! I’ll use a couple of examples of specific C programs I’ve compiled and talk about a few things that can go wrong. Here are three programs we’ll be talking about compiling:

  • paperjam
  • sqlite
  • qf (a pager you can run to quickly open files from a search with rg -n THING | qf)

step 1: install a C compiler

This is pretty simple: on an Ubuntu system if I don’t already have a C compiler I’ll install one with:

sudo apt-get install build-essential

This installs gcc, g++, and make. The situation on a Mac is more confusing but it’s something like “install xcode command line tools”.

step 2: install the program’s dependencies

Unlike some newer programming languages, C doesn’t have a dependency manager. So if a program has any dependencies, you need to hunt them down yourself. Thankfully because of this, C programmers usually keep their dependencies very minimal and often the dependencies will be available in whatever package manager you’re using.

There’s almost always a section explaining how to get the dependencies in the README, for example in paperjam’s README, it says:

To compile PaperJam, you need the headers for the libqpdf and libpaper libraries (usually available as libqpdf-dev and libpaper-dev packages).

You may need a2x (found in AsciiDoc) for building manual pages.

So on a Debian-based system you can install the dependencies like this.

sudo apt install -y libqpdf-dev libpaper-dev

If a README gives a name for a package (like libqpdf-dev), I’d basically always assume that they mean “in a Debian-based Linux distro”: if you’re on a Mac brew install libqpdf-dev will not work. I still have not 100% gotten the hang of developing on a Mac yet so I don’t have many tips there yet. I guess in this case it would be brew install qpdf if you’re using Homebrew.

step 3: run ./configure (if needed)

Some C programs come with a Makefile and some instead come with a script called ./configure. For example, if you download sqlite’s source code, it has a ./configure script in it instead of a Makefile.

My understanding of this ./configure script is:

  1. You run it, it prints out a lot of somewhat inscrutable output, and then it either generates a Makefile or fails because you’re missing some dependency
  2. The ./configure script is part of a system called autotools that I have never needed to learn anything about beyond “run it to generate a Makefile”.

I think there might be some options you can pass to get the ./configure script to produce a different Makefile but I have never done that.

step 4: run make

The next step is to run make to try to build a program. Some notes about make:

  • Sometimes you can run make -j8 to parallelize the build and make it go faster
  • It usually prints out a million compiler warnings when compiling the program. I always just ignore them. I didn’t write the software! The compiler warnings are not my problem.

compiler errors are often dependency problems

Here’s an error I got while compiling paperjam on my Mac:

/opt/homebrew/Cellar/qpdf/12.0.0/include/qpdf/InputSource.hh:85:19: error: function definition does not declare parameters
   85 |     qpdf_offset_t last_offset{0};
      |                   ^

Over the years I’ve learned it’s usually best not to overthink problems like this: if it’s talking about qpdf, there’s a good change it just means that I’ve done something wrong with how I’m including the qpdf dependency.

Now let’s talk about some ways to get the qpdf dependency included in the right way.

the world’s shortest introduction to the compiler and linker

Before we talk about how to fix dependency problems: building C programs is split into 2 steps:

  1. Compiling the code into object files (with gcc or clang)
  2. Linking those object files into a final binary (with ld)

It’s important to know this when building a C program because sometimes you need to pass the right flags to the compiler and linker to tell them where to find the dependencies for the program you’re compiling.

make uses environment variables to configure the compiler and linker

If I run make on my Mac to install paperjam, I get this error:

c++ -o paperjam paperjam.o pdf-tools.o parse.o cmds.o pdf.o -lqpdf -lpaper
ld: library 'qpdf' not found

This is not because qpdf is not installed on my system (it actually is!). But the compiler and linker don’t know how to find the qpdf library. To fix this, we need to:

  • pass "-I/opt/homebrew/include" to the compiler (to tell it where to find the header files)
  • pass "-L/opt/homebrew/lib -liconv" to the linker (to tell it where to find library files and to link in iconv)

And we can get make to pass those extra parameters to the compiler and linker using environment variables! To see how this works: inside paperjam’s Makefile you can see a bunch of environment variables, like LDLIBS here:

paperjam: $(OBJS)
	$(LD) -o $@ $^ $(LDLIBS)

Everything you put into the LDLIBS environment variable gets passed to the linker (ld) as a command line argument.

secret environment variable: CPPFLAGS

Makefiles sometimes define their own environment variables that they pass to the compiler/linker, but make also has a bunch of “implicit” environment variables which it will automatically pass to the C compiler and linker. There’s a full list of implicit environment variables here, but one of them is CPPFLAGS, which gets automatically passed to the C compiler.

(technically it would be more normal to use CXXFLAGS for this, but this particular Makefile hardcodes CXXFLAGS so setting CPPFLAGS was the only way I could find to set the compiler flags without editing the Makefile)

As an aside: it took me a long time to realize how closely tied to C/C++ `make` is -- I used to think that `make` was just a general build system (and of course you can use it for anything!) but it has a lot of affordances for building C/C++ programs that it doesn't have for building any other kind of program.

two ways to pass environment variables to make

I learned thanks to @zwol that there are actually two ways to pass environment variables to make:

  1. CXXFLAGS=xyz make (the usual way)
  2. make CXXFLAGS=xyz

The difference between them is that make CXXFLAGS=xyz will override the value of CXXFLAGS set in the Makefile but CXXFLAGS=xyz make won’t.

I’m not sure which way is the norm but I’m going to use the first way in this post.

how to use CPPFLAGS and LDLIBS to fix this compiler error

Now that we’ve talked about how CPPFLAGS and LDLIBS get passed to the compiler and linker, here’s the final incantation that I used to get the program to build successfully!

CPPFLAGS="-I/opt/homebrew/include" LDLIBS="-L/opt/homebrew/lib -liconv" make paperjam

This passes -I/opt/homebrew/include to the compiler and -L/opt/homebrew/lib -liconv to the linker.

Also I don’t want to pretend that I “magically” knew that those were the right arguments to pass, figuring them out involved a bunch of confused Googling that I skipped over in this post. I will say that:

  • the -I compiler flag tells the compiler which directory to find header files in, like /opt/homebrew/include/qpdf/QPDF.hh
  • the -L linker flag tells the linker which directory to find libraries in, like /opt/homebrew/lib/libqpdf.a
  • the -l linker flag tells the linker which libraries to link in, like -liconv means “link in the iconv library”, or -lm means “link math”

tip: how to just build 1 specific file: make $FILENAME

Yesterday I discovered this cool tool called qf which you can use to quickly open files from the output of ripgrep.

qf is in a big directory of various tools, but I only wanted to compile qf. So I just compiled qf, like this:

make qf

Basically if you know (or can guess) the output filename of the file you’re trying to build, you can tell make to just build that file by running make $FILENAME

tip: you don’t need a Makefile

I sometimes write 5-line C programs with no dependencies, and I just learned that if I have a file called blah.c, I can just compile it like this without creating a Makefile:

make blah

It gets automaticaly expanded to cc -o blah blah.c, which saves a bit of typing. I have no idea if I’m going to remember this (I might just keep typing gcc -o blah blah.c anyway) but it seems like a fun trick.

tip: look at how other packaging systems built the same C program

If you’re having trouble building a C program, maybe other people had problems building it too! Every Linux distribution has build files for every package that they build, so even if you can’t install packages from that distribution directly, maybe you can get tips from that Linux distro for how to build the package. Realizing this (thanks to my friend Dave) was a huge ah-ha moment for me.

For example, this line from the nix package for paperjam says:

  env.NIX_LDFLAGS = lib.optionalString stdenv.hostPlatform.isDarwin "-liconv";

This is basically saying “pass the linker flag -liconv to build this on a Mac”, so that’s a clue we could use to build it.

That same file also says env.NIX_CFLAGS_COMPILE = "-DPOINTERHOLDER_TRANSITION=1";. I’m not sure what this means, but when I try to build the paperjam package I do get an error about something called a PointerHolder, so I guess that’s somehow related to the “PointerHolder transition”.

step 5: installing the binary

Once you’ve managed to compile the program, probably you want to install it somewhere! Some Makefiles have an install target that let you install the tool on your system with make install. I’m always a bit scared of this (where is it going to put the files? what if I want to uninstall them later?), so if I’m compiling a pretty simple program I’ll often just manually copy the binary to install it instead, like this:

cp qf ~/bin

step 6: maybe make your own package!

Once I figured out how to do all of this, I realized that I could use my new make knowledge to contribute a paperjam package to Homebrew! Then I could just brew install paperjam on future systems.

The good thing is that even if the details of how all of the different packaging systems, they fundamentally all use C compilers and linkers.

it can be useful to understand a little about C even if you’re not a C programmer

I think all of this is an interesting example of how it can useful to understand some basics of how C programs work (like “they have header files”) even if you’re never planning to write a nontrivial C program if your life.

It feels good to have some ability to compile C/C++ programs myself, even though I’m still not totally confident about all of the compiler and linker flags and I still plan to never learn anything about how autotools works other than “you run ./configure to generate the Makefile”.

Two things I left out of this post:

  • LD_LIBRARY_PATH / DYLD_LIBRARY_PATH (which you use to tell the dynamic linker at runtime where to find dynamically linked files) because I can’t remember the last time I ran into an LD_LIBRARY_PATH issue and couldn’t find an example.
  • pkg-config, which I think is important but I don’t understand yet

Enterprise-Ready MCP

I've seen a lot of complaints about how MCP isn't ready for the enterprise.

I agree, although maybe not for the reasons you think. But don't worry, this isn't just a rant! I believe we can fix it!

The good news is the recent updates to the MCP authorization spec that separate out the role of the authorization server from the MCP server have now put the building blocks in place to make this a lot easier.

But let's back up and talk about what enterprise buyers expect when they are evaluating AI tools to bring into their companies.

Single Sign-On

At a minimum, an enterprise admin expects to be able to put an application under their single sign-on system. This enables the company to manage which users are allowed to use which applications, and prevents their users from needing to have their own passwords at the applications. The goal is to get every application managed under their single sign-on (SSO) system. Many large companies have more than 200 applications, so having them all managed through their SSO solution is a lot better than employees having to manage 200 passwords for each application!

There's a lot more than SSO too, like lifecycle management, entitlements, and logout. We're tackling these in the IPSIE working group in the OpenID Foundation. But for the purposes of this discussion, let's stick to the basics of SSO.

So what does this have to do with MCP?

An AI agent using MCP is just another application enterprises expect to be able to integrate into their single-sign-on (SSO) system. Let's take the example of Claude. When rolled out at a company, ideally every employee would log in to their company Claude account using the company identity provider (IdP). This lets the enterprise admin decide how many Claude licenses to purchase and who should be able to use it.

Connecting to External Apps

The next thing that should happen after a user logs in to Claude via SSO is they need to connect Claude to their other enterprise apps. This includes the built-in integrations in Claude like Google Calendar and Google Drive, as well as any MCP servers exposed by other apps in use within the enterprise. That could cover other SaaS apps like Zoom, Atlassian, and Slack, as well as home-grown internal apps.

Today, this process involves a somewhat cumbersome series of steps each individual employee must take. Here's an example of what the user needs to do to connect their AI agent to external apps:

First, the user logs in to Claude using SSO. This involves a redirect from Claude to the enterprise IdP where they authenticate with one or more factors, and then are redirected back.

SSO Log in to Claude

Next, they need to connect the external app from within Claude. Claude provides a button to initiate the connection. This takes the user to that app (in this example, Google), which redirects them to the IdP to authenticate again, eventually getting redirected back to the app where an OAuth consent prompt is displayed asking the user to approve access, and finally the user is redirected back to Claude and the connection is established.

Connect Google

The user has to repeat these steps for every MCP server that they want to connect to Claude. There are two main problems with this:

  • This user experience is not great. That's a lot of clicking that the user has to do.
  • The enterprise admin has no visibility or control over the connection established between the two applications.

Both of these are significant problems. If you have even just 10 MCP servers rolled out in the enterprise, you're asking users to click through 10 SSO and OAuth prompts to establish the connections, and it will only get worse as MCP is more widely adopted within apps. But also, should we really be asking the user if it's okay for Claude to access their data in Google Drive? In a company context, that's not actually the user's decision. That decision should be made by the enterprise IT admin.

In "An Open Letter to Third-party Suppliers", Patrick Opet, Chief Information Security Officer of JPMorgan Chase writes:

"Modern integration patterns, however, dismantle these essential boundaries, relying heavily on modern identity protocols (e.g., OAuth) to create direct, often unchecked interactions between third-party services and firms' sensitive internal resources."

Right now, these app-to-app connections are happening behind the back of the IdP. What we need is a way to move the connections between the applications into the IdP where they can be managed by the enterprise admin.

Let's see how this works if we leverage a new (in-progress) OAuth extension called "Identity and Authorization Chaining Across Domains", which I'll refer to as "Cross-App Access" for short, enabling the enterprise IdP to sit in the middle of the OAuth exchange between the two apps.

A Brief Intro to Cross-App Access

In this example, we'll use Claude as the application that is trying to connect to Slack's (hypothetical) MCP server. We'll start with a high-level overview of the flow, and later go over the detailed protocol.

First, the user logs in to Claude through the IdP as normal. This results in Claude getting either an ID token or SAML assertion from the IdP, which tells Claude who the user is. (This works the same for SAML assertions or ID tokens, so I'll use ID tokens in the example from here out.) This is no different than what the user would do today when signing in to Claude.

Step 1 and 2 SSO

Then, instead of prompting the user to connect Slack, Claude takes the ID token back to the IdP in a request that says "Claude is requesting access to this user's Slack account."

The IdP validates the ID token, sees it was issued to Claude, and verifies that the admin has allowed Claude to access Slack on behalf of the given user. Assuming everything checks out, the IdP issues a new token back to Claude.

Step 3 and 4 Cross-Domain Request

Claude takes the intermediate token from the IdP to Slack saying "hi, I would like an access token for the Slack MCP server. The IdP gave me this token with the details of the user to issue the access token for." Slack validates the token the same way it would have validated an ID token. (Remember, Slack is already configured for SSO to the IdP for this customer as well, so it already has a way to validate these tokens.) Slack is able to issue an access token giving Claude access to this user's resources in its MCP server.

Step 5-7 Access Token Request

This solves the two big problems:

  • The exchange happens entirely without any user interaction, so the user never sees any prompts or any OAuth consent screens.
  • Since the IdP sits in between the exchange, this gives the enterprise admin a chance to configure the policies around which applications are allowed this direct connection.

The other nice side effect of this is since there is no user interaction required, the first time a new user logs in to Claude, all their enterprise apps will be automatically connected without them having to click any buttons!

Cross-App Access Protocol

Now let's look at what this looks like in the actual protocol. This is based on the adopted in-progress OAuth specification "Identity and Authorization Chaining Across Domains". This spec is actually a combination of two RFCs: Token Exchange (RFC 8693), and JWT Profile for Authorization Grants (RFC 7523). Both RFCs as well as the "Identity and Authorization Chaining Across Domains" spec are very flexible. While this means it is possible to apply this to many different use cases, it does mean we need to be a bit more specific in how to use it for this use case. For that purpose, I've written a profile of the Identity Chaining draft called "Identity Assertion Authorization Grant" to fill in the missing pieces for the specific use case detailed here.

Let's go through it step by step. For this example we'll use the following entities:

  • Claude - the "Requesting Application", which is attempting to access Slack
  • Slack - the "Resource Application", which has the resources being accessed through MCP
  • Okta - the enterprise identity provider which users at the example company can use to sign in to both apps

Cross-App Access Diagram

Single Sign-On

First, Claude gets the user to sign in using a standard OpenID Connect (or SAML) flow in order to obtain an ID token. There isn't anything unique to this spec regarding this first stage, so I will skip the details of the OpenID Connect flow and we'll start with the ID token as the input to the next step.

Token Exchange

Claude, the requesting application, then makes a Token Exchange request (RFC 8693) to the IdP's token endpoint with the following parameters:

  • requested_token_type: The value urn:ietf:params:oauth:token-type:id-jag indicates that an ID Assertion JWT is being requested.
  • audience: The Issuer URL of the Resource Application's authorization server.
  • subject_token: The identity assertion (e.g. the OpenID Connect ID Token or SAML assertion) for the target end-user.
  • subject_token_type: Either urn:ietf:params:oauth:token-type:id_token or urn:ietf:params:oauth:token-type:saml2 as defined by RFC 8693.

This request will also include the client credentials that Claude would use in a traditional OAuth token request, which could be a client secret or a JWT Bearer Assertion.

POST /oauth2/token HTTP/1.1
Host: acme.okta.com
Content-Type: application/x-www-form-urlencoded

grant_type=urn:ietf:params:oauth:grant-type:token-exchange
&requested_token_type=urn:ietf:params:oauth:token-type:id-jag
&audience=https://auth.slack.com/
&subject_token=eyJraWQiOiJzMTZ0cVNtODhwREo4VGZCXzdrSEtQ...
&subject_token_type=urn:ietf:params:oauth:token-type:id_token
&client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer
&client_assertion=eyJhbGciOiJSUzI1NiIsImtpZCI6IjIyIn0...

ID Assertion Validation and Policy Evaluation

At this point, the IdP evaluates the request and decides whether to issue the requested "ID Assertion JWT". The request will be evaluated based on the validity of the arguments, as well as the configured policy by the customer.

For example, the IdP validates that the ID token in this request was issued to the same client that matches the provided client authentication. It evaluates that the user still exists and is active, and that the user is assigned the Resource Application. Other policies can be evaluated at the discretion of the IdP, just like it can during a single sign-on flow.

If the IdP agrees that the requesting app should be authorized to access the given user's data in the resource app's MCP server, it will respond with a Token Exchange response to issue the token:

HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store

{
  "issued_token_type": "urn:ietf:params:oauth:token-type:id-jag",
  "access_token": "eyJhbGciOiJIUzI1NiIsI...",
  "token_type": "N_A",
  "expires_in": 300
}

The claims in the issued JWT are defined in "Identity Assertion Authorization Grant". The JWT is signed using the same key that the IdP signs ID tokens with. This is a critical aspect that makes this work, since again we assumed that both apps would already be configured for SSO to the IdP so would already be aware of the signing key for that purpose.

At this point, Claude is ready to request a token for the Resource App's MCP server

Access Token Request

The JWT received in the previous request can now be used as a "JWT Authorization Grant" as described by RFC 7523. To do this, Claude makes a request to the MCP authorization server's token endpoint with the following parameters:

  • grant_type: urn:ietf:params:oauth:grant-type:jwt-bearer
  • assertion: The Identity Assertion Authorization Grant JWT obtained in the previous token exchange step

For example:

POST /oauth2/token HTTP/1.1
Host: auth.slack.com
Authorization: Basic yZS1yYW5kb20tc2VjcmV0v3JOkF0XG5Qx2

grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer
assertion=eyJhbGciOiJIUzI1NiIsI...

Slack's authorization server can now evaluate this request to determine whether to issue an access token. The authorization server can validate the JWT by checking the issuer (iss) in the JWT to determine which enterprise IdP the token is from, and then check the signature using the public key discovered at that server. There are other claims to be validated as well, described in Section 6.1 of the Identity Assertion Authorization Grant.

Assuming all the validations pass, Slack is ready to issue an access token to Claude in the token response:

HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store

{
  "token_type": "Bearer",
  "access_token": "2YotnFZFEjr1zCsicMWpAA",
  "expires_in": 86400
}

This token response is the same format that Slack's authorization server would be responding to a traditional OAuth flow. That's another key aspect of this design that makes it scalable. We don't need the resource app to use any particular access token format, since only that server is responsible for validating those tokens.

Now that Claude has the access token, it can make a request to the (hypothetical) Slack MCP server using the bearer token the same way it would have if it got the token using the traditional redirect-based OAuth flow.

Note: Eventually we'll need to define the specific behavior of when to return a refresh token in this token response. The goal is to ensure the client goes through the IdP often enough for the IdP to enforce its access policies. A refresh token could potentially undermine that if the refresh token lifetime is too long. It follows that ultimately the IdP should enforce the refresh token lifetime, so we will need to define a way for the IdP to communicate to the authorization server whether and how long to issue refresh tokens. This would enable the authorization server to make its own decision on access token lifetime, while still respecting the enterprise IdP policy.

Cross-App Access Sequence Diagram

Here's the flow again, this time as a sequence diagram.

Cross-App Access Sequence Diagram

  1. The client initiates a login request
  2. The user's browser is redirected to the IdP
  3. The user logs in at the IdP
  4. The IdP returns an OAuth authorization code to the user's browser
  5. The user's browser delivers the authorization code to the client
  6. The client exchanges the authorization code for an ID token at the IdP
  7. The IdP returns an ID token to the client

At this point, the user is logged in to the MCP client. Everything up until this point has been a standard OpenID Connect flow.

  1. The client makes a direct Token Exchange request to the IdP to exchange the ID token for a cross-domain "ID Assertion JWT"
  2. The IdP validates the request and checks the internal policy
  3. The IdP returns the ID-JAG to the client
  4. The client makes a token request using the ID-JAG to the MCP authorization server
  5. The authorization server validates the token using the signing key it also uses for its OpenID Connect flow with the IdP
  6. The authorization server returns an access token
  7. The client makes a request with the access token to the MCP server
  8. The MCP server returns the response

For a more detailed step by step of the flow, see Appendix A.3 of the Identity Assertion Authorization Grant.

Let's fix OAuth in MCP
Update: The changes described in this blog post have been incorporated into the 2025-06-18 version of the MCP spec!

Let's not overthink auth in MCP.

Yes, the MCP server is going to need its own auth server. But it's not as bad as it sounds. Let me explain.

First let's get a few pieces of terminology straight.

The confusion that's happening in the discussions I've seen so far is because the spec and diagrams show that the MCP server itself is handing authorization. That's not necessary.

oauth roles

In OAuth, we talk about the "authorization server" and "resource server" as distinct roles. I like to think of the authorization server as the "token factory", that's the thing that makes the access tokens. The resource server (usually an API) needs to be able to validate the tokens created by the authorization server.

combined AS and RS

It's possible to build a single server that is both a resource server and authorization server, and in fact many OAuth systems are built that way, especially large consumer services.

separate AS and RS

But nothing about the spec requires that the two roles are combined, it's also possible to run these as two totally unrelated services.

This flexibility that's been baked into OAuth for over a decade is what has led to the rapid adoption, as well the proliferation of open source and commercial products that provide an OAuth authorization server as a service.

So how does this relate to MCP?

I can annotate the flow from the Model Context Protocol spec to show the parts where the client talks to the MCP Resource Server separately from where the client talks to the MCP Authorization Server.

MCP Flow showing AS and RS highlighted

Here is the updated sequence diagram showing communication with each role separately.

New MCP diagram showing separate AS and RS

Why is it important to call out this change?

I've seen a few conversations in various places about how requiring the MCP Server to be both an authorization server and resource server is too much of a burden. But actually, very little needs to change about the spec to enable this separation of concerns that OAuth already provides.

I've also seen various suggestions of other ways to separate the authorization server from the MCP server, like delegating to an enterprise IdP and having the MCP server validate access tokens issued by the IdP. These other options also conflate the OAuth roles in an awkward way and would result in some undesirable properties or relationships between the various parties involved.

So what needs to change in the MCP spec to enable this?

Discovery

The main thing currently forcing the MCP Server to be both the authorization server and resource server is how the client does discovery.

One design goal of MCP is to enable a client to bootstrap everything it needs based on only the server URL provided. I think this is a great design goal, and luckily is something that can be achieved even when separating the roles in the way I've described.

The MCP spec currently says that clients are expected to fetch the OAuth Server Metadata (RFC8414) file from the MCP Server base URL, resulting in a URL such as:

https://example.com/.well-known/oauth-authorization-server

This ends up meaning the MCP Resource Server must also be an Authorization Server, which leads to the complications the community has encountered so far. The good news is there is an OAuth spec we can apply here instead: Protected Resource Metadata.

Protected Resource Metadata

The Protected Resource Metadata spec is used by a Resource Server to advertise metadata about itself, including which Authorization Server can be used with it. This spec is both new and old. It was started in 2016, but was never adopted by the OAuth working group until 2023, after I had presented at an IETF meeting about the need for clients to be able to bootstrap OAuth flows given an OAuth resource server. The spec is now awaiting publication as an RFC, and should get its RFC number in a couple months. (Update: This became RFC 9728 on April 23, 2025!)

Applying this to the MCP server would result in a sequence like the following:

New discovery flow for MCP

  1. The MCP Client fetches the Resource Server Metadata file by appending /.well-known/oauth-protected-resource to the MCP Server base URL.
  2. The MCP Client finds the authorization_servers property in the JSON response, and builds the Authorization Server Metadata URL by appending /.well-known/oauth-authorization-server
  3. The MCP Client fetches the Authorization Server Metadata to find the endpoints it needs for the OAuth flow, the authorization endpoint and token endpoint
  4. The MCP Client initiates an OAuth flow and continues as normal


Note: The Protected Resource Metadata spec also supports the Resource Server returning WWW-Authenticate with a link to the resource metadata URL if you want to avoid the requirement that MCP Servers host their metadata URLs at the .well-known endpoint, it just requires an extra HTTP request to support this.

Access Token Validation

Two things to keep in mind about how the MCP Server validates access tokens with this new separation of concerns.

If you do build the MCP Authorization Server and Resource Server as part of the same system, you don't need to do anything special to validate the access tokens the Authorization Server issues. You probably already have some sort of infrastructure in place for your normal API to validate tokens issued by your Authorization Server, so nothing changes there.

If you are using an external Authorization Server, whether that's an open source product or a commercial hosted service, that product will have its own docs for how you can validate the tokens it creates. There's a good chance it already supports the standardized JWT Access Tokens described in RFC 9068, in which case you can use off-the-shelf JWT validation middleware for common frameworks.

In either case, the critical design goal here is that the MCP Authorization Server issues access tokens that only ever need to be validated by the MCP Resource Server. This is in line with the security recommendations in Section 2.3 of RFC 9700, in particular that "access tokens SHOULD be audience-restricted to a specific resource server". In other words, it would be a bad idea for the MCP Client to be issued an access token that works with both the MCP Resource Server and the service's REST API.

Why Require the MCP Server to have an Authorization Server in the first place?

Another argument I've seen is that MCP Server developers shouldn't have to build any OAuth infrastructure at all, instead they should be able to delegate all the OAuth bits to an external service.

In principle, I agree. Getting API access and authorization right is tricky, that's why there are entire companies dedicated to solving the problem.

The architecture laid out above enables this exact separation of concerns. The difference between this architecture and some of the other proposals I've seen is that this cleanly separates the security boundaries so that there are minimal dependencies among the parties involved.

But, one thing I haven't seen mentioned in the discussions is that there actually is no requirement than an OAuth Authorization Server provide any UI itself.

An Authorization Server with no UI?

While it is desirable from a security perspective that the MCP Resource Server has a corresponding Authorization Server that issues access tokens for it, that Authorization Server doesn't actually need to have any UI or even any concept of user login or accounts. You can actually build an Authorization Server that delegates all user account management to an external service. You can see an example of this in PayPal's MCP server they recently launched.

PayPal's traditional API already supports OAuth, the authorization and token endpoints are:

  • https://www.paypal.com/signin/authorize
  • https://api-m.paypal.com/v1/oauth2/token

When PayPal built their MCP server, they launched it at https://mcp.paypal.com. If you fetch the metadata for the MCP Server, you'll find the two OAuth endpoints for the MCP Authorization Server:

  • https://mcp.paypal.com/authorize
  • https://mcp.paypal.com/token

When the MCP Client redirects the user to the authorization endpoint, the MCP server itself doesn't provide any UI. Instead, it immediately redirects the user to the real PayPal authorization endpoint which then prompts the user to log in and authorize the client.

Roles with backend API and Authorization Servers

This points to yet another benefit of architecting the MCP Authorization Server and Resource Server this way. It enables implementers to delegate the actual user management to their existing OAuth server with no changes needed to the MCP Client. The MCP Client isn't even aware that this extra redirect step was inserted in the middle. As far as the MCP Client is concerned, it has been talking to only the MCP Authorization Server. It just so happens that the MCP Authorization Server has sent the user elsewhere to actually log in.

Dynamic Client Registration

There's one more point I want to make about why having a dedicated MCP Authorization Server is helpful architecturally.

The MCP spec strongly recommends that MCP Servers (authorization servers) support Dynamic Client Registration. If MCP is successful, there will be a large number of MCP Clients talking to a large number of MCP Servers, and the user is the one deciding which combinations of clients and servers to use. This means it is not scalable to require that every MCP Client developer register their client with every MCP Server.

This is similar to the idea of using an email client with the user's chosen email server. Obviously Mozilla can't register Thunderbird with every email server out there. Instead, there needs to be a way to dynamically establish a client's identity with the OAuth server at runtime. Dynamic Client Registration is one option for how to do that.

The problem is most commercial APIs are not going to enable Dynamic Client Registration on their production servers. For example, in order to get client credentials to use the Google APIs, you need to register as a developer and then register an OAuth client after logging in. Dynamic Client Registration would allow a client to register itself without the link to the developer's account. That would mean there is no paper trail for who the client was developed by. The Dynamic Client Registration endpoint can't require authentication by definition, so is a public endpoint that can create clients, which as you can imagine opens up some potential security issues.

I do, however, think it would be reasonable to expect production services to enable Dynamic Client Registration only on the MCP's Authorization Server. This way the dynamically-registered clients wouldn't be able to use the regular REST API, but would only be able to interact with the MCP API.

Mastodon and BlueSky also have a similar problem of needing clients to show up at arbitrary authorization servers without prior coordination between the client developer and authorization server operator. I call this the "OAuth for the Open Web" problem. Mastodon used Dynamic Client Registration as their solution, and has since documented some of the issues that this creates, linked here and here.

BlueSky decided to take a different approach and instead uses an https URL as a client identifier, bypassing the need for a client registration step entirely. This has the added bonus of having at least some level of confidence of the client identity because the client identity is hosted at a domain. It would be a perfectly viable approach to use this method for MCP as well. There is a discussion on that within MCP here. This is an ongoing topic within the OAuth working group, I have a couple of drafts in progress to formalize this pattern, Client ID Metadata Document and Client ID Scheme.

Enterprise IdP Integration

Lastly, I want to touch on the idea of enabling users to log in to MCP Servers with their enterprise IdP.

When an enterprise company purchases software, they expect to be able to tie it in to their single-sign-on solution. For example, when I log in to work Slack, I enter my work email and Slack redirects me to my work IdP where I log in. This way employees don't need to have passwords with every app they use in the enterprise, they can log in to everything with the same enterprise account, and all the apps can be protected with multi-factor authentication through the IdP. This also gives the company control over which users can access which apps, as well as a way to revoke a user's access at any time.

So how does this relate to MCP?

Well, plenty of people are already trying to figure out how to let their employees safely use AI tools within the enterprise. So we need a way to let employees use their enterprise IdP to log in and authorize MCP Clients to access MCP Servers.

If you're building an MCP Server in front of an existing application that already supports enterprise Single Sign-On, then you don't need to do anything differently in the MCP Client or Server and you already have support for this. When the MCP Client redirects to the MCP Authorization Server, the MCP Authorization Server redirects to the main Authorization Server, which would then prompt the user for their company email/domain and redirect to the enterprise IdP to log in.

This brings me to yet another thing I've been seeing conflated in the discussions: user login and user authorization.

OAuth is an authorization delegation protocol. OAuth doesn't actually say anything about how users authenticate at the OAuth server, it only talks about how the user can authorize access to an application. This is actually a really great thing, because it means we can get super creative with how users authenticate.

User logs in and authorizes

Remember the yellow box "User logs in and authorizes" from the original sequence diagram? These are actually two totally distinct steps. The OAuth authorization server is responsible for getting the user to log in somehow, but there's no requirement that how the user logs in is with a username/password. This is where we can insert a single-sign-on flow to an enterprise IdP, or really anything you can imagine.

So think of this as two separate boxes: "user logs in", and "user authorizes". Then, we can replace the "user logs in" box with an entirely new OpenID Connect flow out to the enterprise IdP to log the user in, and after they are logged in they can authorize the client.

User logs in with OIDC

I'll spare you the complete expanded sequence diagram, since it looks a lot more complicated than it actually is. But I again want to stress that this is nothing new, this is already how things are commonly done today.

This all just becomes cleaner to understand when you separate the MCP Authorization Server from the MCP Resource Server.

We can push all the complexity of user login, token minting, and more onto the MCP Authorization Server, keeping the MCP Resource Server free to do the much simpler task of validating access tokens and serving resources.

Future Improvements of Enterprise IdP Integration

There are two things I want to call out about how enterprise IdP integration could be improved. Both of these are entire topics on their own, so I will only touch on the problems and link out to other places where work is happening to solve them.

There are two points of friction with the current state of enterprise login for SaaS apps.

  • IdP discovery
  • User consent

IdP Discovery

When a user logs in to a SaaS app, they need to tell the app how to find their enterprise IdP. This is commonly done by either asking the user to enter their work email, or asking the user to enter their tenant URL at the service.

Sign in with SSO

Neither of these is really a great user experience. It would be a lot better if the browser already knew which enterprise IdP the user should be sent to. This is one of my goals with the work happening in FedCM. With this new browser API, the browser can mediate the login, telling the SaaS app which enterprise IdP to use automatically only needing the user to click their account icon rather than type anything in.

User Consent

Another point of friction in the enterprise happens when a user starts connecting multiple applications to each other within the company. For example, if you drop in a Google Docs link into Slack, Slack will prompt you to connect your Google account to preview the link. Multiply this by N number of applications that can preview links, and M number of applications you might drop links to, and you end up sending the user through a huge number of OAuth consent flows.

The problem is only made worse with the explosion of AI tools. Every AI tool will need access to data in every other application in the enterprise. That is a lot of OAuth consent flows for the user to manage. Plus, the user shouldn't really be the one granting consent for Slack to access the company Google Docs account anyway. That consent should ideally be managed by the enterprise IT admin.

What we actually need is a way to enable the IT admin to grant consent for apps to talk to each other company-wide, removing the need for users to be sent through an OAuth flow at all.

This is the basis of another OAuth spec I've been working on, the Identity Assertion Authorization Grant.

The same problem applies to MCP Servers, and with the separation of concerns laid out above, it becomes straightforward to add this extension to move the consent to the enterprise and streamline the user experience.

Standards for ANSI escape codes

Hello! Today I want to talk about ANSI escape codes.

For a long time I was vaguely aware of ANSI escape codes (“that’s how you make text red in the terminal and stuff”) but I had no real understanding of where they were supposed to be defined or whether or not there were standards for them. I just had a kind of vague “there be dragons” feeling around them. While learning about the terminal this year, I’ve learned that:

  1. ANSI escape codes are responsible for a lot of usability improvements in the terminal (did you know there’s a way to copy to your system clipboard when SSHed into a remote machine?? It’s an escape code called OSC 52!)
  2. They aren’t completely standardized, and because of that they don’t always work reliably. And because they’re also invisible, it’s extremely frustrating to troubleshoot escape code issues.

So I wanted to put together a list for myself of some standards that exist around escape codes, because I want to know if they have to feel unreliable and frustrating, or if there’s a future where we could all rely on them with more confidence.

what’s an escape code?

Have you ever pressed the left arrow key in your terminal and seen ^[[D? That’s an escape code! It’s called an “escape code” because the first character is the “escape” character, which is usually written as ESC, \x1b, \E, \033, or ^[.

Escape codes are how your terminal emulator communicates various kinds of information (colours, mouse movement, etc) with programs running in the terminal. There are two kind of escape codes:

  1. input codes which your terminal emulator sends for keypresses or mouse movements that don’t fit into Unicode. For example “left arrow key” is ESC[D, “Ctrl+left arrow” might be ESC[1;5D, and clicking the mouse might be something like ESC[M :3.
  2. output codes which programs can print out to colour text, move the cursor around, clear the screen, hide the cursor, copy text to the clipboard, enable mouse reporting, set the window title, etc.

Now let’s talk about standards!

ECMA-48

The first standard I found relating to escape codes was ECMA-48, which was originally published in 1976.

ECMA-48 does two things:

  1. Define some general formats for escape codes (like “CSI” codes, which are ESC[ + something and “OSC” codes, which are ESC] + something)
  2. Define some specific escape codes, like how “move the cursor to the left” is ESC[D, or “turn text red” is ESC[31m. In the spec, the “cursor left” one is called CURSOR LEFT and the one for changing colours is called SELECT GRAPHIC RENDITION.

The formats are extensible, so there’s room for others to define more escape codes in the future. Lots of escape codes that are popular today aren’t defined in ECMA-48: for example it’s pretty common for terminal applications (like vim, htop, or tmux) to support using the mouse, but ECMA-48 doesn’t define escape codes for the mouse.

xterm control sequences

There are a bunch of escape codes that aren’t defined in ECMA-48, for example:

  • enabling mouse reporting (where did you click in your terminal?)
  • bracketed paste (did you paste that text or type it in?)
  • OSC 52 (which terminal applications can use to copy text to your system clipboard)

I believe (correct me if I’m wrong!) that these and some others came from xterm, are documented in XTerm Control Sequences, and have been widely implemented by other terminal emulators.

This list of “what xterm supports” is not a standard exactly, but xterm is extremely influential and so it seems like an important document.

terminfo

In the 80s (and to some extent today, but my understanding is that it was MUCH more dramatic in the 80s) there was a huge amount of variation in what escape codes terminals actually supported.

To deal with this, there’s a database of escape codes for various terminals called “terminfo”.

It looks like the standard for terminfo is called X/Open Curses, though you need to create an account to view that standard for some reason. It defines the database format as well as a C library interface (“curses”) for accessing the database.

For example you can run this bash snippet to see every possible escape code for “clear screen” for all of the different terminals your system knows about:

for term in $(toe -a | awk '{print $1}')
do
  echo $term
  infocmp -1 -T "$term" 2>/dev/null | grep 'clear=' | sed 's/clear=//g;s/,//g'
done

On my system (and probably every system I’ve ever used?), the terminfo database is managed by ncurses.

should programs use terminfo?

I think it’s interesting that there are two main approaches that applications take to handling ANSI escape codes:

  1. Use the terminfo database to figure out which escape codes to use, depending on what’s in the TERM environment variable. Fish does this, for example.
  2. Identify a “single common set” of escape codes which works in “enough” terminal emulators and just hardcode those.

Some examples of programs/libraries that take approach #2 (“don’t use terminfo”) include:

I got curious about why folks might be moving away from terminfo and I found this very interesting and extremely detailed rant about terminfo from one of the fish maintainers, which argues that:

[the terminfo authors] have done a lot of work that, at the time, was extremely important and helpful. My point is that it no longer is.

I’m not going to do it justice so I’m not going to summarize it, I think it’s worth reading.

is there a “single common set” of escape codes?

I was just talking about the idea that you can use a “common set” of escape codes that will work for most people. But what is that set? Is there any agreement?

I really do not know the answer to this at all, but from doing some reading it seems like it’s some combination of:

  • The codes that the VT100 supported (though some aren’t relevant on modern terminals)
  • what’s in ECMA-48 (which I think also has some things that are no longer relevant)
  • What xterm supports (though I’d guess that not everything in there is actually widely supported enough)

and maybe ultimately “identify the terminal emulators you think your users are going to use most frequently and test in those”, the same way web developers do when deciding which CSS features are okay to use

I don’t think there are any resources like Can I use…? or Baseline for the terminal though. (in theory terminfo is supposed to be the “caniuse” for the terminal but it seems like it often takes 10+ years to add new terminal features when people invent them which makes it very limited)

some reasons to use terminfo

I also asked on Mastodon why people found terminfo valuable in 2025 and got a few reasons that made sense to me:

  • some people expect to be able to use the TERM environment variable to control how programs behave (for example with TERM=dumb), and there’s no standard for how that should work in a post-terminfo world
  • even though there’s less variation between terminal emulators than there was in the 80s, there’s far from zero variation: there are graphical terminals, the Linux framebuffer console, the situation you’re in when connecting to a server via its serial console, Emacs shell mode, and probably more that I’m missing
  • there is no one standard for what the “single common set” of escape codes is, and sometimes programs use escape codes which aren’t actually widely supported enough

terminfo & user agent detection

The way that ncurses uses the TERM environment variable to decide which escape codes to use reminds me of how webservers used to sometimes use the browser user agent to decide which version of a website to serve.

It also seems like it’s had some of the same results – the way iTerm2 reports itself as being “xterm-256color” feels similar to how Safari’s user agent is “Mozilla/5.0 (Macintosh; Intel Mac OS X 14_7_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.3 Safari/605.1.15”. In both cases the terminal emulator / browser ends up changing its user agent to get around user agent detection that isn’t working well.

On the web we ended up deciding that user agent detection was not a good practice and to instead focus on standardization so we can serve the same HTML/CSS to all browsers. I don’t know if the same approach is the future in the terminal though – I think the terminal landscape today is much more fragmented than the web ever was as well as being much less well funded.

some more documents/standards

A few more documents and standards related to escape codes, in no particular order:

why I think this is interesting

I sometimes see people saying that the unix terminal is “outdated”, and since I love the terminal so much I’m always curious about what incremental changes might make it feel less “outdated”.

Maybe if we had a clearer standards landscape (like we do on the web!) it would be easier for terminal emulator developers to build new features and for authors of terminal applications to more confidently adopt those features so that we can all benefit from them and have a richer experience in the terminal.

Obviously standardizing ANSI escape codes is not easy (ECMA-48 was first published almost 50 years ago and we’re still not there!). I don’t even know what all of the challenges are. But the situation with HTML/CSS/JS used to be extremely bad too and now it’s MUCH better, so maybe there’s hope.

How to add a directory to your PATH

I was talking to a friend about how to add a directory to your PATH today. It’s something that feels “obvious” to me since I’ve been using the terminal for a long time, but when I searched for instructions for how to do it, I actually couldn’t find something that explained all of the steps – a lot of them just said “add this to ~/.bashrc”, but what if you’re not using bash? What if your bash config is actually in a different file? And how are you supposed to figure out which directory to add anyway?

So I wanted to try to write down some more complete directions and mention some of the gotchas I’ve run into over the years.

Here’s a table of contents:

step 1: what shell are you using?

If you’re not sure what shell you’re using, here’s a way to find out. Run this:

ps -p $$ -o pid,comm=
  • if you’re using bash, it’ll print out 97295 bash
  • if you’re using zsh, it’ll print out 97295 zsh
  • if you’re using fish, it’ll print out an error like “In fish, please use $fish_pid” ($$ isn’t valid syntax in fish, but in any case the error message tells you that you’re using fish, which you probably already knew)

Also bash is the default on Linux and zsh is the default on Mac OS (as of 2024). I’ll only cover bash, zsh, and fish in these directions.

step 2: find your shell’s config file

  • in zsh, it’s probably ~/.zshrc
  • in bash, it might be ~/.bashrc, but it’s complicated, see the note in the next section
  • in fish, it’s probably ~/.config/fish/config.fish (you can run echo $__fish_config_dir if you want to be 100% sure)

a note on bash’s config file

Bash has three possible config files: ~/.bashrc, ~/.bash_profile, and ~/.profile.

If you’re not sure which one your system is set up to use, I’d recommend testing this way:

  1. add echo hi there to your ~/.bashrc
  2. Restart your terminal
  3. If you see “hi there”, that means ~/.bashrc is being used! Hooray!
  4. Otherwise remove it and try the same thing with ~/.bash_profile
  5. You can also try ~/.profile if the first two options don’t work.

(there are a lot of elaborate flow charts out there that explain how bash decides which config file to use but IMO it’s not worth it to internalize them and just testing is the fastest way to be sure)

step 3: figure out which directory to add

Let’s say that you’re trying to install and run a program called http-server and it doesn’t work, like this:

$ npm install -g http-server
$ http-server
bash: http-server: command not found

How do you find what directory http-server is in? Honestly in general this is not that easy – often the answer is something like “it depends on how npm is configured”. A few ideas:

  • Often when setting up a new installer (like cargo, npm, homebrew, etc), when you first set it up it’ll print out some directions about how to update your PATH. So if you’re paying attention you can get the directions then.
  • Sometimes installers will automatically update your shell’s config file to update your PATH for you
  • Sometimes just Googling “where does npm install things?” will turn up the answer
  • Some tools have a subcommand that tells you where they’re configured to install things, like:
    • Node/npm: npm config get prefix (then append /bin/)
    • Go: go env GOPATH (then append /bin/)
    • asdf: asdf info | grep ASDF_DIR (then append /bin/ and /shims/)

step 3.1: double check it’s the right directory

Once you’ve found a directory you think might be the right one, make sure it’s actually correct! For example, I found out that on my machine, http-server is in ~/.npm-global/bin. I can make sure that it’s the right directory by trying to run the program http-server in that directory like this:

$ ~/.npm-global/bin/http-server
Starting up http-server, serving ./public

It worked! Now that you know what directory you need to add to your PATH, let’s move to the next step!

step 4: edit your shell config

Now we have the 2 critical pieces of information we need:

  1. Which directory you’re trying to add to your PATH (like ~/.npm-global/bin/)
  2. Where your shell’s config is (like ~/.bashrc, ~/.zshrc, or ~/.config/fish/config.fish)

Now what you need to add depends on your shell:

bash instructions:

Open your shell’s config file, and add a line like this:

export PATH=$PATH:~/.npm-global/bin/

(obviously replace ~/.npm-global/bin with the actual directory you’re trying to add)

zsh instructions:

You can do the same thing as in bash, but zsh also has some slightly fancier syntax you can use if you prefer:

path=(
  $path
  ~/.npm-global/bin
)

fish instructions:

In fish, the syntax is different:

set PATH $PATH ~/.npm-global/bin

(in fish you can also use fish_add_path, some notes on that further down)

step 5: restart your shell

Now, an extremely important step: updating your shell’s config won’t take effect if you don’t restart it!

Two ways to do this:

  1. open a new terminal (or terminal tab), and maybe close the old one so you don’t get confused
  2. Run bash to start a new shell (or zsh if you’re using zsh, or fish if you’re using fish)

I’ve found that both of these usually work fine.

And you should be done! Try running the program you were trying to run and hopefully it works now.

If not, here are a couple of problems that you might run into:

problem 1: it ran the wrong program

If the wrong version of a program is running, you might need to add the directory to the beginning of your PATH instead of the end.

For example, on my system I have two versions of python3 installed, which I can see by running which -a:

$ which -a python3
/usr/bin/python3
/opt/homebrew/bin/python3

The one your shell will use is the first one listed.

If you want to use the Homebrew version, you need to add that directory (/opt/homebrew/bin) to the beginning of your PATH instead, by putting this in your shell’s config file (it’s /opt/homebrew/bin/:$PATH instead of the usual $PATH:/opt/homebrew/bin/)

export PATH=/opt/homebrew/bin/:$PATH

or in fish:

set PATH ~/.cargo/bin $PATH

problem 2: the program isn’t being run from your shell

All of these directions only work if you’re running the program from your shell. If you’re running the program from an IDE, from a GUI, in a cron job, or some other way, you’ll need to add the directory to your PATH in a different way, and the exact details might depend on the situation.

in a cron job

Some options:

  • use the full path to the program you’re running, like /home/bork/bin/my-program
  • put the full PATH you want as the first line of your crontab (something like PATH=/bin:/usr/bin:/usr/local/bin:….). You can get the full PATH you’re using in your shell by running echo "PATH=$PATH".

I’m honestly not sure how to handle it in an IDE/GUI because I haven’t run into that in a long time, will add directions here if someone points me in the right direction.

problem 3: duplicate PATH entries making it harder to debug

If you edit your path and start a new shell by running bash (or zsh, or fish), you’ll often end up with duplicate PATH entries, because the shell keeps adding new things to your PATH every time you start your shell.

Personally I don’t think I’ve run into a situation where this kind of duplication breaks anything, but the duplicates can make it harder to debug what’s going on with your PATH if you’re trying to understand its contents.

Some ways you could deal with this:

  1. If you’re debugging your PATH, open a new terminal to do it in so you get a “fresh” state. This should avoid the duplication.
  2. Deduplicate your PATH at the end of your shell’s config (for example in zsh apparently you can do this with typeset -U path)
  3. Check that the directory isn’t already in your PATH when adding it (for example in fish I believe you can do this with fish_add_path --path /some/directory)

How to deduplicate your PATH is shell-specific and there isn’t always a built in way to do it so you’ll need to look up how to accomplish it in your shell.

problem 4: losing your history after updating your PATH

Here’s a situation that’s easy to get into in bash or zsh:

  1. Run a command (it fails)
  2. Update your PATH
  3. Run bash to reload your config
  4. Press the up arrow a couple of times to rerun the failed command (or open a new terminal)
  5. The failed command isn’t in your history! Why not?

This happens because in bash, by default, history is not saved until you exit the shell.

Some options for fixing this:

  • Instead of running bash to reload your config, run source ~/.bashrc (or source ~/.zshrc in zsh). This will reload the config inside your current session.
  • Configure your shell to continuously save your history instead of only saving the history when the shell exits. (How to do this depends on whether you’re using bash or zsh, the history options in zsh are a bit complicated and I’m not exactly sure what the best way is)

a note on source

When you install cargo (Rust’s installer) for the first time, it gives you these instructions for how to set up your PATH, which don’t mention a specific directory at all.

This is usually done by running one of the following (note the leading DOT):

. "$HOME/.cargo/env"        	# For sh/bash/zsh/ash/dash/pdksh
source "$HOME/.cargo/env.fish"  # For fish

The idea is that you add that line to your shell’s config, and their script automatically sets up your PATH (and potentially other things) for you.

This is pretty common (for example Homebrew suggests you eval brew shellenv), and there are two ways to approach this:

  1. Just do what the tool suggests (like adding . "$HOME/.cargo/env" to your shell’s config)
  2. Figure out which directories the script they’re telling you to run would add to your PATH, and then add those manually. Here’s how I’d do that:
    • Run . "$HOME/.cargo/env" in my shell (or the fish version if using fish)
    • Run echo "$PATH" | tr ':' '\n' | grep cargo to figure out which directories it added
    • See that it says /Users/bork/.cargo/bin and shorten that to ~/.cargo/bin
    • Add the directory ~/.cargo/bin to PATH (with the directions in this post)

I don’t think there’s anything wrong with doing what the tool suggests (it might be the “best way”!), but personally I usually use the second approach because I prefer knowing exactly what configuration I’m changing.

a note on fish_add_path

fish has a handy function called fish_add_path that you can run to add a directory to your PATH like this:

fish_add_path /some/directory

This is cool (it’s such a simple command!) but I’ve stopped using it for a couple of reasons:

  1. Sometimes fish_add_path will update the PATH for every session in the future (with a “universal variable”) and sometimes it will update the PATH just for the current session and it’s hard for me to tell which one it will do. In theory the docs explain this but I could not understand them.
  2. If you ever need to remove the directory from your PATH a few weeks or months later because maybe you made a mistake, it’s kind of hard to do (there are instructions in this comments of this github issue though).

that’s all

Hopefully this will help some people. Let me know (on Mastodon or Bluesky) if you there are other major gotchas that have tripped you up when adding a directory to your PATH, or if you have questions about this post!

Some terminal frustrations

A few weeks ago I ran a terminal survey (you can read the results here) and at the end I asked:

What’s the most frustrating thing about using the terminal for you?

1600 people answered, and I decided to spend a few days categorizing all the responses. Along the way I learned that classifying qualitative data is not easy but I gave it my best shot. I ended up building a custom tool to make it faster to categorize everything.

As with all of my surveys the methodology isn’t particularly scientific. I just posted the survey to Mastodon and Twitter, ran it for a couple of days, and got answers from whoever happened to see it and felt like responding.

Here are the top categories of frustrations!

I think it’s worth keeping in mind while reading these comments that

  • 40% of people answering this survey have been using the terminal for 21+ years
  • 95% of people answering the survey have been using the terminal for at least 4 years

These comments aren’t coming from total beginners.

Here are the categories of frustrations! The number in brackets is the number of people with that frustration. I’m mostly writing this up for myself because I’m trying to write a zine about the terminal and I wanted to get a sense for what people are having trouble with.

remembering syntax (115)

People talked about struggles remembering:

  • the syntax for CLI tools like awk, jq, sed, etc
  • the syntax for redirects
  • keyboard shortcuts for tmux, text editing, etc

One example comment:

There are just so many little “trivia” details to remember for full functionality. Even after all these years I’ll sometimes forget where it’s 2 or 1 for stderr, or forget which is which for > and >>.

switching terminals is hard (91)

People talked about struggling with switching systems (for example home/work computer or when SSHing) and running into:

  • OS differences in keyboard shortcuts (like Linux vs Mac)
  • systems which don’t have their preferred text editor (“no vim” or “only vim”)
  • different versions of the same command (like Mac OS grep vs GNU grep)
  • no tab completion
  • a shell they aren’t used to (“the subtle differences between zsh and bash”)

as well as differences inside the same system like pagers being not consistent with each other (git diff pagers, other pagers).

One example comment:

I got used to fish and vi mode which are not available when I ssh into servers, containers.

color (85)

Lots of problems with color, like:

  • programs setting colors that are unreadable with a light background color
  • finding a colorscheme they like (and getting it to work consistently across different apps)
  • color not working inside several layers of SSH/tmux/etc
  • not liking the defaults
  • not wanting color at all and struggling to turn it off

This comment felt relatable to me:

Getting my terminal theme configured in a reasonable way between the terminal emulator and fish (I did this years ago and remember it being tedious and fiddly and now feel like I’m locked into my current theme because it works and I dread touching any of that configuration ever again).

keyboard shortcuts (84)

Half of the comments on keyboard shortcuts were about how on Linux/Windows, the keyboard shortcut to copy/paste in the terminal is different from in the rest of the OS.

Some other issues with keyboard shortcuts other than copy/paste:

  • using Ctrl-W in a browser-based terminal and closing the window
  • the terminal only supports a limited set of keyboard shortcuts (no Ctrl-Shift-, no Super, no Hyper, lots of ctrl- shortcuts aren’t possible like Ctrl-,)
  • the OS stopping you from using a terminal keyboard shortcut (like by default Mac OS uses Ctrl+left arrow for something else)
  • issues using emacs in the terminal
  • backspace not working (2)

other copy and paste issues (75)

Aside from “the keyboard shortcut for copy and paste is different”, there were a lot of OTHER issues with copy and paste, like:

  • copying over SSH
  • how tmux and the terminal emulator both do copy/paste in different ways
  • dealing with many different clipboards (system clipboard, vim clipboard, the “middle click” clipboard on Linux, tmux’s clipboard, etc) and potentially synchronizing them
  • random spaces added when copying from the terminal
  • pasting multiline commands which automatically get run in a terrifying way
  • wanting a way to copy text without using the mouse

discoverability (55)

There were lots of comments about this, which all came down to the same basic complaint – it’s hard to discover useful tools or features! This comment kind of summed it all up:

How difficult it is to learn independently. Most of what I know is an assorted collection of stuff I’ve been told by random people over the years.

steep learning curve (44)

A lot of comments about it generally having a steep learning curve. A couple of example comments:

After 15 years of using it, I’m not much faster than using it than I was 5 or maybe even 10 years ago.

and

That I know I could make my life easier by learning more about the shortcuts and commands and configuring the terminal but I don’t spend the time because it feels overwhelming.

history (42)

Some issues with shell history:

  • history not being shared between terminal tabs (16)
  • limits that are too short (4)
  • history not being restored when terminal tabs are restored
  • losing history because the terminal crashed
  • not knowing how to search history

One example comment:

It wasted a lot of time until I figured it out and still annoys me that “history” on zsh has such a small buffer; I have to type “history 0” to get any useful length of history.

bad documentation (37)

People talked about:

  • documentation being generally opaque
  • lack of examples in man pages
  • programs which don’t have man pages

Here’s a representative comment:

Finding good examples and docs. Man pages often not enough, have to wade through stack overflow

scrollback (36)

A few issues with scrollback:

  • programs printing out too much data making you lose scrollback history
  • resizing the terminal messes up the scrollback
  • lack of timestamps
  • GUI programs that you start in the background printing stuff out that gets in the way of other programs’ outputs

One example comment:

When resizing the terminal (in particular: making it narrower) leads to broken rewrapping of the scrollback content because the commands formatted their output based on the terminal window width.

“it feels outdated” (33)

Lots of comments about how the terminal feels hampered by legacy decisions and how users often end up needing to learn implementation details that feel very esoteric. One example comment:

Most of the legacy cruft, it would be great to have a green field implementation of the CLI interface.

shell scripting (32)

Lots of complaints about POSIX shell scripting. There’s a general feeling that shell scripting is difficult but also that switching to a different less standard scripting language (fish, nushell, etc) brings its own problems.

Shell scripting. My tolerance to ditch a shell script and go to a scripting language is pretty low. It’s just too messy and powerful. Screwing up can be costly so I don’t even bother.

more issues

Some more issues that were mentioned at least 10 times:

  • (31) inconsistent command line arguments: is it -h or help or –help?
  • (24) keeping dotfiles in sync across different systems
  • (23) performance (e.g. “my shell takes too long to start”)
  • (20) window management (potentially with some combination of tmux tabs, terminal tabs, and multiple terminal windows. Where did that shell session go?)
  • (17) generally feeling scared/uneasy (“The debilitating fear that I’m going to do some mysterious Bad Thing with a command and I will have absolutely no idea how to fix or undo it or even really figure out what happened”)
  • (16) terminfo issues (“Having to learn about terminfo if/when I try a new terminal emulator and ssh elsewhere.”)
  • (16) lack of image support (sixel etc)
  • (15) SSH issues (like having to start over when you lose the SSH connection)
  • (15) various tmux/screen issues (for example lack of integration between tmux and the terminal emulator)
  • (15) typos & slow typing
  • (13) the terminal getting messed up for various reasons (pressing Ctrl-S, cating a binary, etc)
  • (12) quoting/escaping in the shell
  • (11) various Windows/PowerShell issues

n/a (122)

There were also 122 answers to the effect of “nothing really” or “only that I can’t do EVERYTHING in the terminal”

One example comment:

Think I’ve found work arounds for most/all frustrations

that’s all!

I’m not going to make a lot of commentary on these results, but here are a couple of categories that feel related to me:

  • remembering syntax & history (often the thing you need to remember is something you’ve run before!)
  • discoverability & the learning curve (the lack of discoverability is definitely a big part of what makes it hard to learn)
  • “switching systems is hard” & “it feels outdated” (tools that haven’t really changed in 30 or 40 years have many problems but they do tend to be always there no matter what system you’re on, which is very useful and makes them hard to stop using)

Trying to categorize all these results in a reasonable way really gave me an appreciation for social science researchers’ skills.

What's involved in getting a "modern" terminal setup?

Hello! Recently I ran a terminal survey and I asked people what frustrated them. One person commented:

There are so many pieces to having a modern terminal experience. I wish it all came out of the box.

My immediate reaction was “oh, getting a modern terminal experience isn’t that hard, you just need to….”, but the more I thought about it, the longer the “you just need to…” list got, and I kept thinking about more and more caveats.

So I thought I would write down some notes about what it means to me personally to have a “modern” terminal experience and what I think can make it hard for people to get there.

what is a “modern terminal experience”?

Here are a few things that are important to me, with which part of the system is responsible for them:

  • multiline support for copy and paste: if you paste 3 commands in your shell, it should not immediately run them all! That’s scary! (shell, terminal emulator)
  • infinite shell history: if I run a command in my shell, it should be saved forever, not deleted after 500 history entries or whatever. Also I want commands to be saved to the history immediately when I run them, not only when I exit the shell session (shell)
  • a useful prompt: I can’t live without having my current directory and current git branch in my prompt (shell)
  • 24-bit colour: this is important to me because I find it MUCH easier to theme neovim with 24-bit colour support than in a terminal with only 256 colours (terminal emulator)
  • clipboard integration between vim and my operating system so that when I copy in Firefox, I can just press p in vim to paste (text editor, maybe the OS/terminal emulator too)
  • good autocomplete: for example commands like git should have command-specific autocomplete (shell)
  • having colours in ls (shell config)
  • a terminal theme I like: I spend a lot of time in my terminal, I want it to look nice and I want its theme to match my terminal editor’s theme. (terminal emulator, text editor)
  • automatic terminal fixing: If a programs prints out some weird escape codes that mess up my terminal, I want that to automatically get reset so that my terminal doesn’t get messed up (shell)
  • keybindings: I want Ctrl+left arrow to work (shell or application)
  • being able to use the scroll wheel in programs like less: (terminal emulator and applications)

There are a million other terminal conveniences out there and different people value different things, but those are the ones that I would be really unhappy without.

how I achieve a “modern experience”

My basic approach is:

  1. use the fish shell. Mostly don’t configure it, except to:
    • set the EDITOR environment variable to my favourite terminal editor
    • alias ls to ls --color=auto
  2. use any terminal emulator with 24-bit colour support. In the past I’ve used GNOME Terminal, Terminator, and iTerm, but I’m not picky about this. I don’t really configure it other than to choose a font.
  3. use neovim, with a configuration that I’ve been very slowly building over the last 9 years or so (the last time I deleted my vim config and started from scratch was 9 years ago)
  4. use the base16 framework to theme everything

A few things that affect my approach:

  • I don’t spend a lot of time SSHed into other machines
  • I’d rather use the mouse a little than come up with keyboard-based ways to do everything
  • I work on a lot of small projects, not one big project

some “out of the box” options for a “modern” experience

What if you want a nice experience, but don’t want to spend a lot of time on configuration? Figuring out how to configure vim in a way that I was satisfied with really did take me like ten years, which is a long time!

My best ideas for how to get a reasonable terminal experience with minimal config are:

  • shell: either fish or zsh with oh-my-zsh
  • terminal emulator: almost anything with 24-bit colour support, for example all of these are popular:
    • linux: GNOME Terminal, Konsole, Terminator, xfce4-terminal
    • mac: iTerm (Terminal.app doesn’t have 256-colour support)
    • cross-platform: kitty, alacritty, wezterm, or ghostty
  • shell config:
    • set the EDITOR environment variable to your favourite terminal text editor
    • maybe alias ls to ls --color=auto
  • text editor: this is a tough one, maybe micro or helix? I haven’t used either of them seriously but they both seem like very cool projects and I think it’s amazing that you can just use all the usual GUI editor commands (Ctrl-C to copy, Ctrl-V to paste, Ctrl-A to select all) in micro and they do what you’d expect. I would probably try switching to helix except that retraining my vim muscle memory seems way too hard. Also helix doesn’t have a GUI or plugin system yet.

Personally I wouldn’t use xterm, rxvt, or Terminal.app as a terminal emulator, because I’ve found in the past that they’re missing core features (like 24-bit colour in Terminal.app’s case) that make the terminal harder to use for me.

I don’t want to pretend that getting a “modern” terminal experience is easier than it is though – I think there are two issues that make it hard. Let’s talk about them!

issue 1 with getting to a “modern” experience: the shell

bash and zsh are by far the two most popular shells, and neither of them provide a default experience that I would be happy using out of the box, for example:

  • you need to customize your prompt
  • they don’t come with git completions by default, you have to set them up
  • by default, bash only stores 500 (!) lines of history and (at least on Mac OS) zsh is only configured to store 2000 lines, which is still not a lot
  • I find bash’s tab completion very frustrating, if there’s more than one match then you can’t tab through them

And even though I love fish, the fact that it isn’t POSIX does make it hard for a lot of folks to make the switch.

Of course it’s totally possible to learn how to customize your prompt in bash or whatever, and it doesn’t even need to be that complicated (in bash I’d probably start with something like export PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ ', or maybe use starship). But each of these “not complicated” things really does add up and it’s especially tough if you need to keep your config in sync across several systems.

An extremely popular solution to getting a “modern” shell experience is oh-my-zsh. It seems like a great project and I know a lot of people use it very happily, but I’ve struggled with configuration systems like that in the past – it looks like right now the base oh-my-zsh adds about 3000 lines of config, and often I find that having an extra configuration system makes it harder to debug what’s happening when things go wrong. I personally have a tendency to use the system to add a lot of extra plugins, make my system slow, get frustrated that it’s slow, and then delete it completely and write a new config from scratch.

issue 2 with getting to a “modern” experience: the text editor

In the terminal survey I ran recently, the most popular terminal text editors by far were vim, emacs, and nano.

I think the main options for terminal text editors are:

  • use vim or emacs and configure it to your liking, you can probably have any feature you want if you put in the work
  • use nano and accept that you’re going to have a pretty limited experience (for example I don’t think you can select text with the mouse and then “cut” it in nano)
  • use micro or helix which seem to offer a pretty good out-of-the-box experience, potentially occasionally run into issues with using a less mainstream text editor
  • just avoid using a terminal text editor as much as possible, maybe use VSCode, use VSCode’s terminal for all your terminal needs, and mostly never edit files in the terminal. Or I know a lot of people use code as their EDITOR in the terminal.

issue 3: individual applications

The last issue is that sometimes individual programs that I use are kind of annoying. For example on my Mac OS machine, /usr/bin/sqlite3 doesn’t support the Ctrl+Left Arrow keyboard shortcut. Fixing this to get a reasonable terminal experience in SQLite was a little complicated, I had to:

  • realize why this is happening (Mac OS won’t ship GNU tools, and “Ctrl-Left arrow” support comes from GNU readline)
  • find a workaround (install sqlite from homebrew, which does have readline support)
  • adjust my environment (put Homebrew’s sqlite3 in my PATH)

I find that debugging application-specific issues like this is really not easy and often it doesn’t feel “worth it” – often I’ll end up just dealing with various minor inconveniences because I don’t want to spend hours investigating them. The only reason I was even able to figure this one out at all is that I’ve been spending a huge amount of time thinking about the terminal recently.

A big part of having a “modern” experience using terminal programs is just using newer terminal programs, for example I can’t be bothered to learn a keyboard shortcut to sort the columns in top, but in htop I can just click on a column heading with my mouse to sort it. So I use htop instead! But discovering new more “modern” command line tools isn’t easy (though I made a list here), finding ones that I actually like using in practice takes time, and if you’re SSHed into another machine, they won’t always be there.

everything affects everything else

Something I find tricky about configuring my terminal to make everything “nice” is that changing one seemingly small thing about my workflow can really affect everything else. For example right now I don’t use tmux. But if I needed to use tmux again (for example because I was doing a lot of work SSHed into another machine), I’d need to think about a few things, like:

  • if I wanted tmux’s copy to synchronize with my system clipboard over SSH, I’d need to make sure that my terminal emulator has OSC 52 support
  • if I wanted to use iTerm’s tmux integration (which makes tmux tabs into iTerm tabs), I’d need to change how I configure colours – right now I set them with a shell script that I run when my shell starts, but that means the colours get lost when restoring a tmux session.

and probably more things I haven’t thought of. “Using tmux means that I have to change how I manage my colours” sounds unlikely, but that really did happen to me and I decided “well, I don’t want to change how I manage colours right now, so I guess I’m not using that feature!”.

It’s also hard to remember which features I’m relying on – for example maybe my current terminal does have OSC 52 support and because copying from tmux over SSH has always Just Worked I don’t even realize that that’s something I need, and then it mysteriously stops working when I switch terminals.

change things slowly

Personally even though I think my setup is not that complicated, it’s taken me 20 years to get to this point! Because terminal config changes are so likely to have unexpected and hard-to-understand consequences, I’ve found that if I change a lot of terminal configuration all at once it makes it much harder to understand what went wrong if there’s a problem, which can be really disorienting.

So I usually prefer to make pretty small changes, and accept that changes can might take me a REALLY long time to get used to. For example I switched from using ls to eza a year or two ago and while I like it (because eza -l prints human-readable file sizes by default) I’m still not quite sure about it. But also sometimes it’s worth it to make a big change, like I made the switch to fish (from bash) 10 years ago and I’m very happy I did.

getting a “modern” terminal is not that easy

Trying to explain how “easy” it is to configure your terminal really just made me think that it’s kind of hard and that I still sometimes get confused.

I’ve found that there’s never one perfect way to configure things in the terminal that will be compatible with every single other thing. I just need to try stuff, figure out some kind of locally stable state that works for me, and accept that if I start using a new tool it might disrupt the system and I might need to rethink things.

"Rules" that terminal programs follow

Recently I’ve been thinking about how everything that happens in the terminal is some combination of:

  1. Your operating system’s job
  2. Your shell’s job
  3. Your terminal emulator’s job
  4. The job of whatever program you happen to be running (like top or vim or cat)

The first three (your operating system, shell, and terminal emulator) are all kind of known quantities – if you’re using bash in GNOME Terminal on Linux, you can more or less reason about how how all of those things interact, and some of their behaviour is standardized by POSIX.

But the fourth one (“whatever program you happen to be running”) feels like it could do ANYTHING. How are you supposed to know how a program is going to behave?

This post is kind of long so here’s a quick table of contents:

programs behave surprisingly consistently

As far as I know, there are no real standards for how programs in the terminal should behave – the closest things I know of are:

  • POSIX, which mostly dictates how your terminal emulator / OS / shell should work together. I think it does specify a few things about how core utilities like cp should work but AFAIK it doesn’t have anything to say about how for example htop should behave.
  • these command line interface guidelines

But even though there are no standards, in my experience programs in the terminal behave in a pretty consistent way. So I wanted to write down a list of “rules” that in my experience programs mostly follow.

these are meant to be descriptive, not prescriptive

My goal here isn’t to convince authors of terminal programs that they should follow any of these rules. There are lots of exceptions to these and often there’s a good reason for those exceptions.

But it’s very useful for me to know what behaviour to expect from a random new terminal program that I’m using. Instead of “uh, programs could do literally anything”, it’s “ok, here are the basic rules I expect, and then I can keep a short mental list of exceptions”.

So I’m just writing down what I’ve observed about how programs behave in my 20 years of using the terminal, why I think they behave that way, and some examples of cases where that rule is “broken”.

it’s not always obvious which “rules” are the program’s responsibility to implement

There are a bunch of common conventions that I think are pretty clearly the program’s responsibility to implement, like:

  • config files should go in ~/.BLAHrc or ~/.config/BLAH/FILE or /etc/BLAH/ or something
  • --help should print help text
  • programs should print “regular” output to stdout and errors to stderr

But in this post I’m going to focus on things that it’s not 100% obvious are the program’s responsibility. For example it feels to me like a “law of nature” that pressing Ctrl-D should quit a REPL, but programs often need to explicitly implement support for it – even though cat doesn’t need to implement Ctrl-D support, ipython does. (more about that in “rule 3” below)

Understanding which things are the program’s responsibility makes it much less surprising when different programs’ implementations are slightly different.

rule 1: noninteractive programs should quit when you press Ctrl-C

The main reason for this rule is that noninteractive programs will quit by default on Ctrl-C if they don’t set up a SIGINT signal handler, so this is kind of a “you should act like the default” rule.

Something that trips a lot of people up is that this doesn’t apply to interactive programs like python3 or bc or less. This is because in an interactive program, Ctrl-C has a different job – if the program is running an operation (like for example a search in less or some Python code in python3), then Ctrl-C will interrupt that operation but not stop the program.

As an example of how this works in an interactive program: here’s the code in prompt-toolkit (the library that iPython uses for handling input) that aborts a search when you press Ctrl-C.

rule 2: TUIs should quit when you press q

TUI programs (like less or htop) will usually quit when you press q.

This rule doesn’t apply to any program where pressing q to quit wouldn’t make sense, like tmux or text editors.

rule 3: REPLs should quit when you press Ctrl-D on an empty line

REPLs (like python3 or ed) will usually quit when you press Ctrl-D on an empty line. This rule is similar to the Ctrl-C rule – the reason for this is that by default if you’re running a program (like cat) in “cooked mode”, then the operating system will return an EOF when you press Ctrl-D on an empty line.

Most of the REPLs I use (sqlite3, python3, fish, bash, etc) don’t actually use cooked mode, but they all implement this keyboard shortcut anyway to mimic the default behaviour.

For example, here’s the code in prompt-toolkit that quits when you press Ctrl-D, and here’s the same code in readline.

I actually thought that this one was a “Law of Terminal Physics” until very recently because I’ve basically never seen it broken, but you can see that it’s just something that each individual input library has to implement in the links above.

Someone pointed out that the Erlang REPL does not quit when you press Ctrl-D, so I guess not every REPL follows this “rule”.

rule 4: don’t use more than 16 colours

Terminal programs rarely use colours other than the base 16 ANSI colours. This is because if you specify colours with a hex code, it’s very likely to clash with some users’ background colour. For example if I print out some text as #EEEEEE, it would be almost invisible on a white background, though it would look fine on a dark background.

But if you stick to the default 16 base colours, you have a much better chance that the user has configured those colours in their terminal emulator so that they work reasonably well with their background color. Another reason to stick to the default base 16 colours is that it makes less assumptions about what colours the terminal emulator supports.

The only programs I usually see breaking this “rule” are text editors, for example Helix by default will use a purple background which is not a default ANSI colour. It seems fine for Helix to break this rule since Helix isn’t a “core” program and I assume any Helix user who doesn’t like that colorscheme will just change the theme.

rule 5: vaguely support readline keybindings

Almost every program I use supports readline keybindings if it would make sense to do so. For example, here are a bunch of different programs and a link to where they define Ctrl-E to go to the end of the line:

None of those programs actually uses readline directly, they just sort of mimic emacs/readline keybindings. They don’t always mimic them exactly: for example atuin seems to use Ctrl-A as a prefix, so Ctrl-A doesn’t go to the beginning of the line.

Also all of these programs seem to implement their own internal cut and paste buffers so you can delete a line with Ctrl-U and then paste it with Ctrl-Y.

The exceptions to this are:

  • some programs (like git, cat, and nc) don’t have any line editing support at all (except for backspace, Ctrl-W, and Ctrl-U)
  • as usual text editors are an exception, every text editor has its own approach to editing text

I wrote more about this “what keybindings does a program support?” question in entering text in the terminal is complicated.

rule 5.1: Ctrl-W should delete the last word

I’ve never seen a program (other than a text editor) where Ctrl-W doesn’t delete the last word. This is similar to the Ctrl-C rule – by default if a program is in “cooked mode”, the OS will delete the last word if you press Ctrl-W, and delete the whole line if you press Ctrl-U. So usually programs will imitate that behaviour.

I can’t think of any exceptions to this other than text editors but if there are I’d love to hear about them!

rule 6: disable colours when writing to a pipe

Most programs will disable colours when writing to a pipe. For example:

  • rg blah will highlight all occurrences of blah in the output, but if the output is to a pipe or a file, it’ll turn off the highlighting.
  • ls --color=auto will use colour when writing to a terminal, but not when writing to a pipe

Both of those programs will also format their output differently when writing to the terminal: ls will organize files into columns, and ripgrep will group matches with headings.

If you want to force the program to use colour (for example because you want to look at the colour), you can use unbuffer to force the program’s output to be a tty like this:

unbuffer rg blah |  less -R

I’m sure that there are some programs that “break” this rule but I can’t think of any examples right now. Some programs have an --color flag that you can use to force colour to be on, in the example above you could also do rg --color=always | less -R.

rule 7: - means stdin/stdout

Usually if you pass - to a program instead of a filename, it’ll read from stdin or write to stdout (whichever is appropriate). For example, if you want to format the Python code that’s on your clipboard with black and then copy it, you could run:

pbpaste | black - | pbcopy

(pbpaste is a Mac program, you can do something similar on Linux with xclip)

My impression is that most programs implement this if it would make sense and I can’t think of any exceptions right now, but I’m sure there are many exceptions.

these “rules” take a long time to learn

These rules took me a long time for me to learn because I had to:

  1. learn that the rule applied anywhere at all ("Ctrl-C will exit programs")
  2. notice some exceptions (“okay, Ctrl-C will exit find but not less”)
  3. subconsciously figure out what the pattern is ("Ctrl-C will generally quit noninteractive programs, but in interactive programs it might interrupt the current operation instead of quitting the program")
  4. eventually maybe formulate it into an explicit rule that I know

A lot of my understanding of the terminal is honestly still in the “subconscious pattern recognition” stage. The only reason I’ve been taking the time to make things explicit at all is because I’ve been trying to explain how it works to others. Hopefully writing down these “rules” explicitly will make learning some of this stuff a little bit faster for others.

Why pipes sometimes get "stuck": buffering

Here’s a niche terminal problem that has bothered me for years but that I never really understood until a few weeks ago. Let’s say you’re running this command to watch for some specific output in a log file:

tail -f /some/log/file | grep thing1 | grep thing2

If log lines are being added to the file relatively slowly, the result I’d see is… nothing! It doesn’t matter if there were matches in the log file or not, there just wouldn’t be any output.

I internalized this as “uh, I guess pipes just get stuck sometimes and don’t show me the output, that’s weird”, and I’d handle it by just running grep thing1 /some/log/file | grep thing2 instead, which would work.

So as I’ve been doing a terminal deep dive over the last few months I was really excited to finally learn exactly why this happens.

why this happens: buffering

The reason why “pipes get stuck” sometimes is that it’s VERY common for programs to buffer their output before writing it to a pipe or file. So the pipe is working fine, the problem is that the program never even wrote the data to the pipe!

This is for performance reasons: writing all output immediately as soon as you can uses more system calls, so it’s more efficient to save up data until you have 8KB or so of data to write (or until the program exits) and THEN write it to the pipe.

In this example:

tail -f /some/log/file | grep thing1 | grep thing2

the problem is that grep thing1 is saving up all of its matches until it has 8KB of data to write, which might literally never happen.

programs don’t buffer when writing to a terminal

Part of why I found this so disorienting is that tail -f file | grep thing will work totally fine, but then when you add the second grep, it stops working!! The reason for this is that the way grep handles buffering depends on whether it’s writing to a terminal or not.

Here’s how grep (and many other programs) decides to buffer its output:

  • Check if stdout is a terminal or not using the isatty function
    • If it’s a terminal, use line buffering (print every line immediately as soon as you have it)
    • Otherwise, use “block buffering” – only print data if you have at least 8KB or so of data to print

So if grep is writing directly to your terminal then you’ll see the line as soon as it’s printed, but if it’s writing to a pipe, you won’t.

Of course the buffer size isn’t always 8KB for every program, it depends on the implementation. For grep the buffering is handled by libc, and libc’s buffer size is defined in the BUFSIZ variable. Here’s where that’s defined in glibc.

(as an aside: “programs do not use 8KB output buffers when writing to a terminal” isn’t, like, a law of terminal physics, a program COULD use an 8KB buffer when writing output to a terminal if it wanted, it would just be extremely weird if it did that, I can’t think of any program that behaves that way)

commands that buffer & commands that don’t

One annoying thing about this buffering behaviour is that you kind of need to remember which commands buffer their output when writing to a pipe.

Some commands that don’t buffer their output:

  • tail
  • cat
  • tee

I think almost everything else will buffer output, especially if it’s a command where you’re likely to be using it for batch processing. Here’s a list of some common commands that buffer their output when writing to a pipe, along with the flag that disables block buffering.

  • grep (--line-buffered)
  • sed (-u)
  • awk (there’s a fflush() function)
  • tcpdump (-l)
  • jq (-u)
  • tr (-u)
  • cut (can’t disable buffering)

Those are all the ones I can think of, lots of unix commands (like sort) may or may not buffer their output but it doesn’t matter because sort can’t do anything until it finishes receiving input anyway.

Also I did my best to test both the Mac OS and GNU versions of these but there are a lot of variations and I might have made some mistakes.

programming languages where the default “print” statement buffers

Also, here are a few programming language where the default print statement will buffer output when writing to a pipe, and some ways to disable buffering if you want:

  • C (disable with setvbuf)
  • Python (disable with python -u, or PYTHONUNBUFFERED=1, or sys.stdout.reconfigure(line_buffering=False), or print(x, flush=True))
  • Ruby (disable with STDOUT.sync = true)
  • Perl (disable with $| = 1)

I assume that these languages are designed this way so that the default print function will be fast when you’re doing batch processing.

Also whether output is buffered or not might depend on how you print, for example in C++ cout << "hello\n" buffers when writing to a pipe but cout << "hello" << endl will flush its output.

when you press Ctrl-C on a pipe, the contents of the buffer are lost

Let’s say you’re running this command as a hacky way to watch for DNS requests to example.com, and you forgot to pass -l to tcpdump:

sudo tcpdump -ni any port 53 | grep example.com

When you press Ctrl-C, what happens? In a magical perfect world, what I would want to happen is for tcpdump to flush its buffer, grep would search for example.com, and I would see all the output I missed.

But in the real world, what happens is that all the programs get killed and the output in tcpdump’s buffer is lost.

I think this problem is probably unavoidable – I spent a little time with strace to see how this works and grep receives the SIGINT before tcpdump anyway so even if tcpdump tried to flush its buffer grep would already be dead.

After a little more investigation, there is a workaround: if you find tcpdump’s PID and kill -TERM $PID, then tcpdump will flush the buffer so you can see the output. That’s kind of a pain but I tested it and it seems to work.

redirecting to a file also buffers

It’s not just pipes, this will also buffer:

sudo tcpdump -ni any port 53 > output.txt

Redirecting to a file doesn’t have the same “Ctrl-C will totally destroy the contents of the buffer” problem though – in my experience it usually behaves more like you’d want, where the contents of the buffer get written to the file before the program exits. I’m not 100% sure whether this is something you can always rely on or not.

a bunch of potential ways to avoid buffering

Okay, let’s talk solutions. Let’s say you’ve run this command:

tail -f /some/log/file | grep thing1 | grep thing2

I asked people on Mastodon how they would solve this in practice and there were 5 basic approaches. Here they are:

solution 1: run a program that finishes quickly

Historically my solution to this has been to just avoid the “command writing to pipe slowly” situation completely and instead run a program that will finish quickly like this:

cat /some/log/file | grep thing1 | grep thing2 | tail

This doesn’t do the same thing as the original command but it does mean that you get to avoid thinking about these weird buffering issues.

(you could also do grep thing1 /some/log/file but I often prefer to use an “unnecessary” cat)

solution 2: remember the “line buffer” flag to grep

You could remember that grep has a flag to avoid buffering and pass it like this:

tail -f /some/log/file | grep --line-buffered thing1 | grep thing2

solution 3: use awk

Some people said that if they’re specifically dealing with a multiple greps situation, they’ll rewrite it to use a single awk instead, like this:

tail -f /some/log/file |  awk '/thing1/ && /thing2/'

Or you would write a more complicated grep, like this:

tail -f /some/log/file |  grep -E 'thing1.*thing2'

(awk also buffers, so for this to work you’ll want awk to be the last command in the pipeline)

solution 4: use stdbuf

stdbuf uses LD_PRELOAD to turn off libc’s buffering, and you can use it to turn off output buffering like this:

tail -f /some/log/file | stdbuf -o0 grep thing1 | grep thing2

Like any LD_PRELOAD solution it’s a bit unreliable – it doesn’t work on static binaries, I think won’t work if the program isn’t using libc’s buffering, and doesn’t always work on Mac OS. Harry Marr has a really nice How stdbuf works post.

solution 5: use unbuffer

unbuffer program will force the program’s output to be a TTY, which means that it’ll behave the way it normally would on a TTY (less buffering, colour output, etc). You could use it in this example like this:

tail -f /some/log/file | unbuffer grep thing1 | grep thing2

Unlike stdbuf it will always work, though it might have unwanted side effects, for example grep thing1’s will also colour matches.

If you want to install unbuffer, it’s in the expect package.

that’s all the solutions I know about!

It’s a bit hard for me to say which one is “best”, I think personally I’m mostly likely to use unbuffer because I know it’s always going to work.

If I learn about more solutions I’ll try to add them to this post.

I’m not really sure how often this comes up

I think it’s not very common for me to have a program that slowly trickles data into a pipe like this, normally if I’m using a pipe a bunch of data gets written very quickly, processed by everything in the pipeline, and then everything exits. The only examples I can come up with right now are:

  • tcpdump
  • tail -f
  • watching log files in a different way like with kubectl logs
  • the output of a slow computation

what if there were an environment variable to disable buffering?

I think it would be cool if there were a standard environment variable to turn off buffering, like PYTHONUNBUFFERED in Python. I got this idea from a couple of blog posts by Mark Dominus in 2018. Maybe NO_BUFFER like NO_COLOR?

The design seems tricky to get right; Mark points out that NETBSD has environment variables called STDBUF, STDBUF1, etc which gives you a ton of control over buffering but I imagine most developers don’t want to implement many different environment variables to handle a relatively minor edge case.

I’m also curious about whether there are any programs that just automatically flush their output buffers after some period of time (like 1 second). It feels like it would be nice in theory but I can’t think of any program that does that so I imagine there are some downsides.

stuff I left out

Some things I didn’t talk about in this post since these posts have been getting pretty long recently and seriously does anyone REALLY want to read 3000 words about buffering?

  • the difference between line buffering and having totally unbuffered output
  • how buffering to stderr is different from buffering to stdout
  • this post is only about buffering that happens inside the program, your operating system’s TTY driver also does a little bit of buffering sometimes
  • other reasons you might need to flush your output other than “you’re writing to a pipe”

Importing a frontend Javascript library without a build system

I like writing Javascript without a build system and for the millionth time yesterday I ran into a problem where I needed to figure out how to import a Javascript library in my code without using a build system, and it took FOREVER to figure out how to import it because the library’s setup instructions assume that you’re using a build system.

Luckily at this point I’ve mostly learned how to navigate this situation and either successfully use the library or decide it’s too difficult and switch to a different library, so here’s the guide I wish I had to importing Javascript libraries years ago.

I’m only going to talk about using Javacript libraries on the frontend, and only about how to use them in a no-build-system setup.

In this post I’m going to talk about:

  1. the three main types of Javascript files a library might provide (ES Modules, the “classic” global variable kind, and CommonJS)
  2. how to figure out which types of files a Javascript library includes in its build
  3. ways to import each type of file in your code

the three kinds of Javascript files

There are 3 basic types of Javascript files a library can provide:

  1. the “classic” type of file that defines a global variable. This is the kind of file that you can just <script src> and it’ll Just Work. Great if you can get it but not always available
  2. an ES module (which may or may not depend on other files, we’ll get to that)
  3. a “CommonJS” module. This is for Node, you can’t use it in a browser at all without using a build system.

I’m not sure if there’s a better name for the “classic” type but I’m just going to call it “classic”. Also there’s a type called “AMD” but I’m not sure how relevant it is in 2024.

Now that we know the 3 types of files, let’s talk about how to figure out which of these the library actually provides!

where to find the files: the NPM build

Every Javascript library has a build which it uploads to NPM. You might be thinking (like I did originally) – Julia! The whole POINT is that we’re not using Node to build our library! Why are we talking about NPM?

But if you’re using a link from a CDN like https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.4.1/chart.umd.min.js, you’re still using the NPM build! All the files on the CDNs originally come from NPM.

Because of this, I sometimes like to npm install the library even if I’m not planning to use Node to build my library at all – I’ll just create a new temp folder, npm install there, and then delete it when I’m done. I like being able to poke around in the files in the NPM build on my filesystem, because then I can be 100% sure that I’m seeing everything that the library is making available in its build and that the CDN isn’t hiding something from me.

So let’s npm install a few libraries and try to figure out what types of Javascript files they provide in their builds!

example library 1: chart.js

First let’s look inside Chart.js, a plotting library.

$ cd /tmp/whatever
$ npm install chart.js
$ cd node_modules/chart.js/dist
$ ls *.*js
chart.cjs  chart.js  chart.umd.js  helpers.cjs  helpers.js

This library seems to have 3 basic options:

option 1: chart.cjs. The .cjs suffix tells me that this is a CommonJS file, for using in Node. This means it’s impossible to use it directly in the browser without some kind of build step.

option 2:chart.js. The .js suffix by itself doesn’t tell us what kind of file it is, but if I open it up, I see import '@kurkle/color'; which is an immediate sign that this is an ES module – the import ... syntax is ES module syntax.

option 3: chart.umd.js. “UMD” stands for “Universal Module Definition”, which I think means that you can use this file either with a basic <script src>, CommonJS, or some third thing called AMD that I don’t understand.

how to use a UMD file

When I was using Chart.js I picked Option 3. I just needed to add this to my code:

<script src="./chart.umd.js"> </script>

and then I could use the library with the global Chart environment variable. Couldn’t be easier. I just copied chart.umd.js into my Git repository so that I didn’t have to worry about using NPM or the CDNs going down or anything.

the build files aren’t always in the dist directory

A lot of libraries will put their build in the dist directory, but not always! The build files’ location is specified in the library’s package.json.

For example here’s an excerpt from Chart.js’s package.json.

  "jsdelivr": "./dist/chart.umd.js",
  "unpkg": "./dist/chart.umd.js",
  "main": "./dist/chart.cjs",
  "module": "./dist/chart.js",

I think this is saying that if you want to use an ES Module (module) you should use dist/chart.js, but the jsDelivr and unpkg CDNs should use ./dist/chart.umd.js. I guess main is for Node.

chart.js’s package.json also says "type": "module", which according to this documentation tells Node to treat files as ES modules by default. I think it doesn’t tell us specifically which files are ES modules and which ones aren’t but it does tell us that something in there is an ES module.

example library 2: @atcute/oauth-browser-client

@atcute/oauth-browser-client is a library for logging into Bluesky with OAuth in the browser.

Let’s see what kinds of Javascript files it provides in its build!

$ npm install @atcute/oauth-browser-client
$ cd node_modules/@atcute/oauth-browser-client/dist
$ ls *js
constants.js  dpop.js  environment.js  errors.js  index.js  resolvers.js

It seems like the only plausible root file in here is index.js, which looks something like this:

export { configureOAuth } from './environment.js';
export * from './errors.js';
export * from './resolvers.js';

This export syntax means it’s an ES module. That means we can use it in the browser without a build step! Let’s see how to do that.

how to use an ES module with importmaps

Using an ES module isn’t an easy as just adding a <script src="whatever.js">. Instead, if the ES module has dependencies (like @atcute/oauth-browser-client does) the steps are:

  1. Set up an import map in your HTML
  2. Put import statements like import { configureOAuth } from '@atcute/oauth-browser-client'; in your JS code
  3. Include your JS code in your HTML like this: <script type="module" src="YOURSCRIPT.js"></script>

The reason we need an import map instead of just doing something like import { BrowserOAuthClient } from "./oauth-client-browser.js" is that internally the module has more import statements like import {something} from @atcute/client, and we need to tell the browser where to get the code for @atcute/client and all of its other dependencies.

Here’s what the importmap I used looks like for @atcute/oauth-browser-client:

<script type="importmap">
{
  "imports": {
    "nanoid": "./node_modules/nanoid/bin/dist/index.js",
    "nanoid/non-secure": "./node_modules/nanoid/non-secure/index.js",
    "nanoid/url-alphabet": "./node_modules/nanoid/url-alphabet/dist/index.js",
    "@atcute/oauth-browser-client": "./node_modules/@atcute/oauth-browser-client/dist/index.js",
    "@atcute/client": "./node_modules/@atcute/client/dist/index.js",
    "@atcute/client/utils/did": "./node_modules/@atcute/client/dist/utils/did.js"
  }
}
</script>

Getting these import maps to work is pretty fiddly, I feel like there must be a tool to generate them automatically but I haven’t found one yet. It’s definitely possible to write a script that automatically generates the importmaps using esbuild’s metafile but I haven’t done that and maybe there’s a better way.

I decided to set up importmaps yesterday to get github.com/jvns/bsky-oauth-example to work, so there’s some example code in that repo.

Also someone pointed me to Simon Willison’s download-esm, which will download an ES module and rewrite the imports to point to the JS files directly so that you don’t need importmaps. I haven’t tried it yet but it seems like a great idea.

problems with importmaps: too many files

I did run into some problems with using importmaps in the browser though – it needed to download dozens of Javascript files to load my site, and my webserver in development couldn’t keep up for some reason. I kept seeing files fail to load randomly and then had to reload the page and hope that they would succeed this time.

It wasn’t an issue anymore when I deployed my site to production, so I guess it was a problem with my local dev environment.

Also one slightly annoying thing about ES modules in general is that you need to be running a webserver to use them, I’m sure this is for a good reason but it’s easier when you can just open your index.html file without starting a webserver.

Because of the “too many files” thing I think actually using ES modules with importmaps in this way isn’t actually that appealing to me, but it’s good to know it’s possible.

how to use an ES module without importmaps

If the ES module doesn’t have dependencies then it’s even easier – you don’t need the importmaps! You can just:

  • put <script type="module" src="YOURCODE.js"></script> in your HTML. The type="module" is important.
  • put import {whatever} from "https://example.com/whatever.js" in YOURCODE.js

alternative: use esbuild

If you don’t want to use importmaps, you can also use a build system like esbuild. I talked about how to do that in Some notes on using esbuild, but this blog post is about ways to avoid build systems completely so I’m not going to talk about that option here. I do still like esbuild though and I think it’s a good option in this case.

what’s the browser support for importmaps?

CanIUse says that importmaps are in “Baseline 2023: newly available across major browsers” so my sense is that in 2024 that’s still maybe a little bit too new? I think I would use importmaps for some fun experimental code that I only wanted like myself and 12 people to use, but if I wanted my code to be more widely usable I’d use esbuild instead.

example library 3: @atproto/oauth-client-browser

Let’s look at one final example library! This is a different Bluesky auth library than @atcute/oauth-browser-client.

$ npm install @atproto/oauth-client-browser
$ cd node_modules/@atproto/oauth-client-browser/dist
$ ls *js
browser-oauth-client.js  browser-oauth-database.js  browser-runtime-implementation.js  errors.js  index.js  indexed-db-store.js  util.js

Again, it seems like only real candidate file here is index.js. But this is a different situation from the previous example library! Let’s take a look at index.js:

There’s a bunch of stuff like this in index.js:

__exportStar(require("@atproto/oauth-client"), exports);
__exportStar(require("./browser-oauth-client.js"), exports);
__exportStar(require("./errors.js"), exports);
var util_js_1 = require("./util.js");

This require() syntax is CommonJS syntax, which means that we can’t use this file in the browser at all, we need to use some kind of build step, and ESBuild won’t work either.

Also in this library’s package.json it says "type": "commonjs" which is another way to tell it’s CommonJS.

how to use a CommonJS module with esm.sh

Originally I thought it was impossible to use CommonJS modules without learning a build system, but then someone Bluesky told me about esm.sh! It’s a CDN that will translate anything into an ES Module. skypack.dev does something similar, I’m not sure what the difference is but one person mentioned that if one doesn’t work sometimes they’ll try the other one.

For @atproto/oauth-client-browser using it seems pretty simple, I just need to put this in my HTML:

<script type="module" src="script.js"> </script>

and then put this in script.js.

import { BrowserOAuthClient } from "https://esm.sh/@atproto/oauth-client-browser@0.3.0"

It seems to Just Work, which is cool! Of course this is still sort of using a build system – it’s just that esm.sh is running the build instead of me. My main concerns with this approach are:

  • I don’t really trust CDNs to keep working forever – usually I like to copy dependencies into my repository so that they don’t go away for some reason in the future.
  • I’ve heard of some issues with CDNs having security compromises which scares me.
  • I don’t really understand what esm.sh is doing.

esbuild can also convert CommonJS modules into ES modules

I also learned that you can also use esbuild to convert a CommonJS module into an ES module, though there are some limitations – the import { BrowserOAuthClient } from syntax doesn’t work. Here’s a github issue about that.

I think the esbuild approach is probably more appealing to me than the esm.sh approach because it’s a tool that I already have on my computer so I trust it more. I haven’t experimented with this much yet though.

summary of the three types of files

Here’s a summary of the three types of JS files you might encounter, options for how to use them, and how to identify them.

Unhelpfully a .js or .min.js file extension could be any of these 3 options, so if the file is something.js you need to do more detective work to figure out what you’re dealing with.

  1. “classic” JS files
    • How to use it:: <script src="whatever.js"></script>
    • Ways to identify it:
      • The website has a big friendly banner in its setup instructions saying “Use this with a CDN!” or something
      • A .umd.js extension
      • Just try to put it in a <script src=... tag and see if it works
  2. ES Modules
    • Ways to use it:
      • If there are no dependencies, just import {whatever} from "./my-module.js" directly in your code
      • If there are dependencies, create an importmap and import {whatever} from "my-module"
      • Use esbuild or any ES Module bundler
    • Ways to identify it:
      • Look for an import or export statement. (not module.exports = ..., that’s CommonJS)
      • An .mjs extension
      • maybe "type": "module" in package.json (though it’s not clear to me which file exactly this refers to)
  3. CommonJS Modules
    • Ways to use it:
      • Use https://esm.sh to convert it into an ES module, like https://esm.sh/@atproto/oauth-client-browser@0.3.0
      • Use a build somehow (??)
    • Ways to identify it:
      • Look for require() or module.exports = ... in the code
      • A .cjs extension
      • maybe "type": "commonjs" in package.json (though it’s not clear to me which file exactly this refers to)

it’s really nice to have ES modules standardized

The main difference between CommonJS modules and ES modules from my perspective is that ES modules are actually a standard. This makes me feel a lot more confident using them, because browsers commit to backwards compatibility for web standards forever – if I write some code using ES modules today, I can feel sure that it’ll still work the same way in 15 years.

It also makes me feel better about using tooling like esbuild because even if the esbuild project dies, because it’s implementing a standard it feels likely that there will be another similar tool in the future that I can replace it with.

the JS community has built a lot of very cool tools

A lot of the time when I talk about this stuff I get responses like “I hate javascript!!! it’s the worst!!!”. But my experience is that there are a lot of great tools for Javascript (I just learned about https://esm.sh yesterday which seems great! I love esbuild!), and that if I take the time to learn how things works I can take advantage of some of those tools and make my life a lot easier.

So the goal of this post is definitely not to complain about Javascript, it’s to understand the landscape so I can use the tooling in a way that feels good to me.

questions I still have

Here are some questions I still have, I’ll add the answers into the post if I learn the answer.

  • Is there a tool that automatically generates importmaps for an ES Module that I have set up locally? (apparently yes: jspm)
  • How can I convert a CommonJS module into an ES module on my computer, the way https://esm.sh does? (apparently esbuild can sort of do this, though named exports don’t work)
  • When people normally build CommonJS modules into regular JS code, what’s code is doing that? Obviously there are tools like webpack, rollup, esbuild, etc, but do those tools all implement their own JS parsers/static analysis? How many JS parsers are there out there?
  • Is there any way to bundle an ES module into a single file (like atcute-client.js), but so that in the browser I can still import multiple different paths from that file (like both @atcute/client/lexicons and @atcute/client)?

all the tools

Here’s a list of every tool we talked about in this post:

Writing this post has made me think that even though I usually don’t want to have a build that I run every time I update the project, I might be willing to have a build step (using download-esm or something) that I run only once when setting up the project and never run again except maybe if I’m updating my dependency versions.

that’s all!

Thanks to Marco Rogers who taught me a lot of the things in this post. I’ve probably made some mistakes in this post and I’d love to know what they are – let me know on Bluesky or Mastodon!

New microblog with TILs

I added a new section to this site a couple weeks ago called TIL (“today I learned”).

the goal: save interesting tools & facts I posted on social media

One kind of thing I like to post on Mastodon/Bluesky is “hey, here’s a cool thing”, like the great SQLite repl litecli, or the fact that cross compiling in Go Just Works and it’s amazing, or cryptographic right answers, or this great diff tool. Usually I don’t want to write a whole blog post about those things because I really don’t have much more to say than “hey this is useful!”

It started to bother me that I didn’t have anywhere to put those things: for example recently I wanted to use diffdiff and I just could not remember what it was called.

the solution: make a new section of this blog

So I quickly made a new folder called /til/, added some custom styling (I wanted to style the posts to look a little bit like a tweet), made a little Rake task to help me create new posts quickly (rake new_til), and set up a separate RSS Feed for it.

I think this new section of the blog might be more for myself than anything, now when I forget the link to Cryptographic Right Answers I can hopefully look it up on the TIL page. (you might think “julia, why not use bookmarks??” but I have been failing to use bookmarks for my whole life and I don’t see that changing ever, putting things in public is for whatever reason much easier for me)

So far it’s been working, often I can actually just make a quick post in 2 minutes which was the goal.

inspired by Simon Willison’s TIL blog

My page is inspired by Simon Willison’s great TIL blog, though my TIL posts are a lot shorter.

I don’t necessarily want everything to be archived

This came about because I spent a lot of time on Twitter, so I’ve been thinking about what I want to do about all of my tweets.

I keep reading the advice to “POSSE” (“post on your own site, syndicate elsewhere”), and while I find the idea appealing in principle, for me part of the appeal of social media is that it’s a little bit ephemeral. I can post polls or questions or observations or jokes and then they can just kind of fade away as they become less relevant.

I find it a lot easier to identify specific categories of things that I actually want to have on a Real Website That I Own:

and then let everything else be kind of ephemeral.

I really believe in the advice to make email lists though – the first two (blog posts & comics) both have email lists and RSS feeds that people can subscribe to if they want. I might add a quick summary of any TIL posts from that week to the “blog posts from this week” mailing list.

ASCII control characters in my terminal

Hello! I’ve been thinking about the terminal a lot and yesterday I got curious about all these “control codes”, like Ctrl-A, Ctrl-C, Ctrl-W, etc. What’s the deal with all of them?

a table of ASCII control characters

Here’s a table of all 33 ASCII control characters, and what they do on my machine (on Mac OS), more or less. There are about a million caveats, but I’ll talk about what it means and all the problems with this diagram that I know about.

You can also view it as an HTML page (I just made it an image so it would show up in RSS).

different kinds of codes are mixed together

The first surprising thing about this diagram to me is that there are 33 control codes, split into (very roughly speaking) these categories:

  1. Codes that are handled by the operating system’s terminal driver, for example when the OS sees a 3 (Ctrl-C), it’ll send a SIGINT signal to the current program
  2. Everything else is passed through to the application as-is and the application can do whatever it wants with them. Some subcategories of those:
    • Codes that correspond to a literal keypress of a key on your keyboard (Enter, Tab, Backspace). For example when you press Enter, your terminal gets sent 13.
    • Codes used by readline: “the application can do whatever it wants” often means “it’ll do more or less what the readline library does, whether the application actually uses readline or not”, so I’ve labelled a bunch of the codes that readline uses
    • Other codes, for example I think Ctrl-X has no standard meaning in the terminal in general but emacs uses it very heavily

There’s no real structure to which codes are in which categories, they’re all just kind of randomly scattered because this evolved organically.

(If you’re curious about readline, I wrote more about readline in entering text in the terminal is complicated, and there are a lot of cheat sheets out there)

there are only 33 control codes

Something else that I find a little surprising is that are only 33 control codes – A to Z, plus 7 more (@, [, \, ], ^, _, ?). This means that if you want to have for example Ctrl-1 as a keyboard shortcut in a terminal application, that’s not really meaningful – on my machine at least Ctrl-1 is exactly the same thing as just pressing 1, Ctrl-3 is the same as Ctrl-[, etc.

Also Ctrl+Shift+C isn’t a control code – what it does depends on your terminal emulator. On Linux Ctrl-Shift-X is often used by the terminal emulator to copy or open a new tab or paste for example, it’s not sent to the TTY at all.

Also I use Ctrl+Left Arrow all the time, but that isn’t a control code, instead it sends an ANSI escape sequence (ctrl-[[1;5D) which is a different thing which we absolutely do not have space for in this post.

This “there are only 33 codes” thing is totally different from how keyboard shortcuts work in a GUI where you can have Ctrl+KEY for any key you want.

the official ASCII names aren’t very meaningful to me

Each of these 33 control codes has a name in ASCII (for example 3 is ETX). When all of these control codes were originally defined, they weren’t being used for computers or terminals at all, they were used for the telegraph machine. Telegraph machines aren’t the same as UNIX terminals so a lot of the codes were repurposed to mean something else.

Personally I don’t find these ASCII names very useful, because 50% of the time the name in ASCII has no actual relationship to what that code does on UNIX systems today. So it feels easier to just ignore the ASCII names completely instead of trying to figure which ones still match their original meaning.

It’s hard to use Ctrl-M as a keyboard shortcut

Another thing that’s a bit weird is that Ctrl-M is literally the same as Enter, and Ctrl-I is the same as Tab, which makes it hard to use those two as keyboard shortcuts.

From some quick research, it seems like some folks do still use Ctrl-I and Ctrl-M as keyboard shortcuts (here’s an example), but to do that you need to configure your terminal emulator to treat them differently than the default.

For me the main takeaway is that if I ever write a terminal application I should avoid Ctrl-I and Ctrl-M as keyboard shortcuts in it.

how to identify what control codes get sent

While writing this I needed to do a bunch of experimenting to figure out what various key combinations did, so I wrote this Python script echo-key.py that will print them out.

There’s probably a more official way but I appreciated having a script I could customize.

caveat: on canonical vs noncanonical mode

Two of these codes (Ctrl-W and Ctrl-U) are labelled in the table as “handled by the OS”, but actually they’re not always handled by the OS, it depends on whether the terminal is in “canonical” mode or in “noncanonical mode”.

In canonical mode, programs only get input when you press Enter (and the OS is in charge of deleting characters when you press Backspace or Ctrl-W). But in noncanonical mode the program gets input immediately when you press a key, and the Ctrl-W and Ctrl-U codes are passed through to the program to handle any way it wants.

Generally in noncanonical mode the program will handle Ctrl-W and Ctrl-U similarly to how the OS does, but there are some small differences.

Some examples of programs that use canonical mode:

  • probably pretty much any noninteractive program, like grep or cat
  • git, I think

Examples of programs that use noncanonical mode:

  • python3, irb and other REPLs
  • your shell
  • any full screen TUI like less or vim

caveat: all of the “OS terminal driver” codes are configurable with stty

I said that Ctrl-C sends SIGINT but technically this is not necessarily true, if you really want to you can remap all of the codes labelled “OS terminal driver”, plus Backspace, using a tool called stty, and you can view the mappings with stty -a.

Here are the mappings on my machine right now:

$ stty -a
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
	eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V;
	min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T;
	stop = ^S; susp = ^Z; time = 0; werase = ^W;

I have personally never remapped any of these and I cannot imagine a reason I would (I think it would be a recipe for confusion and disaster for me), but I asked on Mastodon and people said the most common reasons they used stty were:

  • fix a broken terminal with stty sane
  • set stty erase ^H to change how Backspace works
  • set stty ixoff
  • some people even map SIGINT to a different key, like their DELETE key

caveat: on signals

Two signals caveats:

  1. If the ISIG terminal mode is turned off, then the OS won’t send signals. For example vim turns off ISIG
  2. Apparently on BSDs, there’s an extra control code (Ctrl-T) which sends SIGINFO

You can see which terminal modes a program is setting using strace like this, terminal modes are set with the ioctl system call:

$ strace -tt -o out  vim
$ grep ioctl out | grep SET

here are the modes vim sets when it starts (ISIG and ICANON are missing!):

17:43:36.670636 ioctl(0, TCSETS, {c_iflag=IXANY|IMAXBEL|IUTF8,
c_oflag=NL0|CR0|TAB0|BS0|VT0|FF0|OPOST, c_cflag=B38400|CS8|CREAD,
c_lflag=ECHOK|ECHOCTL|ECHOKE|PENDIN, ...}) = 0

and it resets the modes when it exits:

17:43:38.027284 ioctl(0, TCSETS, {c_iflag=ICRNL|IXANY|IMAXBEL|IUTF8,
c_oflag=NL0|CR0|TAB0|BS0|VT0|FF0|OPOST|ONLCR, c_cflag=B38400|CS8|CREAD,
c_lflag=ISIG|ICANON|ECHO|ECHOE|ECHOK|IEXTEN|ECHOCTL|ECHOKE|PENDIN, ...}) = 0

I think the specific combination of modes vim is using here might be called “raw mode”, man cfmakeraw talks about that.

there are a lot of conflicts

Related to “there are only 33 codes”, there are a lot of conflicts where different parts of the system want to use the same code for different things, for example by default Ctrl-S will freeze your screen, but if you turn that off then readline will use Ctrl-S to do a forward search.

Another example is that on my machine sometimes Ctrl-T will send SIGINFO and sometimes it’ll transpose 2 characters and sometimes it’ll do something completely different depending on:

  • whether the program has ISIG set
  • whether the program uses readline / imitates readline’s behaviour

caveat: on “backspace” and “other backspace”

In this diagram I’ve labelled code 127 as “backspace” and 8 as “other backspace”. Uh, what?

I think this was the single biggest topic of discussion in the replies on Mastodon – apparently there’s a LOT of history to this and I’d never heard of any of it before.

First, here’s how it works on my machine:

  1. I press the Backspace key
  2. The TTY gets sent the byte 127, which is called DEL in ASCII
  3. the OS terminal driver and readline both have 127 mapped to “backspace” (so it works both in canonical mode and noncanonical mode)
  4. The previous character gets deleted

If I press Ctrl+H, it has the same effect as Backspace if I’m using readline, but in a program without readline support (like cat for instance), it just prints out ^H.

Apparently Step 2 above is different for some folks – their Backspace key sends the byte 8 instead of 127, and so if they want Backspace to work then they need to configure the OS (using stty) to set erase = ^H.

There’s an incredible section of the Debian Policy Manual on keyboard configuration that describes how Delete and Backspace should work according to Debian policy, which seems very similar to how it works on my Mac today. My understanding (via this mastodon post) is that this policy was written in the 90s because there was a lot of confusion about what Backspace should do in the 90s and there needed to be a standard to get everything to work.

There’s a bunch more historical terminal stuff here but that’s all I’ll say for now.

there’s probably a lot more diversity in how this works

I’ve probably missed a bunch more ways that “how it works on my machine” might be different from how it works on other people’s machines, and I’ve probably made some mistakes about how it works on my machine too. But that’s all I’ve got for today.

Some more stuff I know that I’ve left out: according to stty -a Ctrl-O is “discard”, Ctrl-R is “reprint”, and Ctrl-Y is “dsusp”. I have no idea how to make those actually do anything (pressing them does not do anything obvious, and some people have told me what they used to do historically but it’s not clear to me if they have a use in 2024), and a lot of the time in practice they seem to just be passed through to the application anyway so I just labelled Ctrl-R and Ctrl-Y as readline.

not all of this is that useful to know

Also I want to say that I think the contents of this post are kind of interesting but I don’t think they’re necessarily that useful. I’ve used the terminal pretty successfully every day for the last 20 years without knowing literally any of this – I just knew what Ctrl-C, Ctrl-D, Ctrl-Z, Ctrl-R, Ctrl-L did in practice (plus maybe Ctrl-A, Ctrl-E and Ctrl-W) and did not worry about the details for the most part, and that was almost always totally fine except when I was trying to use xterm.js.

But I had fun learning about it so maybe it’ll be interesting to you too.

Using less memory to look up IP addresses in Mess With DNS

I’ve been having problems for the last 3 years or so where Mess With DNS periodically runs out of memory and gets OOM killed.

This hasn’t been a big priority for me: usually it just goes down for a few minutes while it restarts, and it only happens once a day at most, so I’ve just been ignoring. But last week it started actually causing a problem so I decided to look into it.

This was kind of winding road where I learned a lot so here’s a table of contents:

there’s about 100MB of memory available

I run Mess With DNS on a VM without about 465MB of RAM, which according to ps aux (the RSS column) is split up something like:

  • 100MB for PowerDNS
  • 200MB for Mess With DNS
  • 40MB for hallpass

That leaves about 110MB of memory free.

A while back I set GOMEMLIMIT to 250MB to try to make sure the garbage collector ran if Mess With DNS used more than 250MB of memory, and I think this helped but it didn’t solve everything.

the problem: OOM killing the backup script

A few weeks ago I started backing up Mess With DNS’s database for the first time using restic.

This has been working okay, but since Mess With DNS operates without much extra memory I think restic sometimes needed more memory than was available on the system, and so the backup script sometimes got OOM killed.

This was a problem because

  1. backups might be corrupted sometimes
  2. more importantly, restic takes out a lock when it runs, and so I’d have to manually do an unlock if I wanted the backups to continue working. Doing manual work like this is the #1 thing I try to avoid with all my web services (who has time for that!) so I really wanted to do something about it.

There’s probably more than one solution to this, but I decided to try to make Mess With DNS use less memory so that there was more available memory on the system, mostly because it seemed like a fun problem to try to solve.

what’s using memory: IP addresses

I’d run a memory profile of Mess With DNS a bunch of times in the past, so I knew exactly what was using most of Mess With DNS’s memory: IP addresses.

When it starts, Mess With DNS loads this database where you can look up the ASN of every IP address into memory, so that when it receives a DNS query it can take the source IP address like 74.125.16.248 and tell you that IP address belongs to GOOGLE.

This database by itself used about 117MB of memory, and a simple du told me that was too much – the original text files were only 37MB!

$ du -sh *.tsv
26M	ip2asn-v4.tsv
11M	ip2asn-v6.tsv

The way it worked originally is that I had an array of these:

type IPRange struct {
	StartIP net.IP
	EndIP   net.IP
	Num     int
	Name    string
	Country string
}

and I searched through it with a binary search to figure out if any of the ranges contained the IP I was looking for. Basically the simplest possible thing and it’s super fast, my machine can do about 9 million lookups per second.

attempt 1: use SQLite

I’ve been using SQLite recently, so my first thought was – maybe I can store all of this data on disk in an SQLite database, give the tables an index, and that’ll use less memory.

So I:

  • wrote a quick Python script using sqlite-utils to import the TSV files into an SQLite database
  • adjusted my code to select from the database instead

This did solve the initial memory goal (after a GC it now hardly used any memory at all because the table was on disk!), though I’m not sure how much GC churn this solution would cause if we needed to do a lot of queries at once. I did a quick memory profile and it seemed to allocate about 1KB of memory per lookup.

Let’s talk about the issues I ran into with using SQLite though.

problem: how to store IPv6 addresses

SQLite doesn’t have support for big integers and IPv6 addresses are 128 bits, so I decided to store them as text. I think BLOB might have been better, I originally thought BLOBs couldn’t be compared but the sqlite docs say they can.

I ended up with this schema:

CREATE TABLE ipv4_ranges (
   start_ip INTEGER NOT NULL,
   end_ip INTEGER NOT NULL,
   asn INTEGER NOT NULL,
   country TEXT NOT NULL,
   name TEXT NOT NULL
);
CREATE TABLE ipv6_ranges (
   start_ip TEXT NOT NULL,
   end_ip TEXT NOT NULL,
   asn INTEGER,
   country TEXT,
   name TEXT
);
CREATE INDEX idx_ipv4_ranges_start_ip ON ipv4_ranges (start_ip);
CREATE INDEX idx_ipv6_ranges_start_ip ON ipv6_ranges (start_ip);
CREATE INDEX idx_ipv4_ranges_end_ip ON ipv4_ranges (end_ip);
CREATE INDEX idx_ipv6_ranges_end_ip ON ipv6_ranges (end_ip);

Also I learned that Python has an ipaddress module, so I could use ipaddress.ip_address(s).exploded to make sure that the IPv6 addresses were expanded so that a string comparison would compare them properly.

problem: it’s 500x slower

I ran a quick microbenchmark, something like this. It printed out that it could look up 17,000 IPv6 addresses per second, and similarly for IPv4 addresses.

This was pretty discouraging – being able to look up 17k addresses per section is kind of fine (Mess With DNS does not get a lot of traffic), but I compared it to the original binary search code and the original code could do 9 million per second.

	ips := []net.IP{}
	count := 20000
	for i := 0; i < count; i++ {
		// create a random IPv6 address
		bytes := randomBytes()
		ip := net.IP(bytes[:])
		ips = append(ips, ip)
	}
	now := time.Now()
	success := 0
	for _, ip := range ips {
		_, err := ranges.FindASN(ip)
		if err == nil {
			success++
		}
	}
	fmt.Println(success)
	elapsed := time.Since(now)
	fmt.Println("number per second", float64(count)/elapsed.Seconds())

time for EXPLAIN QUERY PLAN

I’d never really done an EXPLAIN in sqlite, so I thought it would be a fun opportunity to see what the query plan was doing.

sqlite> explain query plan select * from ipv6_ranges where '2607:f8b0:4006:0824:0000:0000:0000:200e' BETWEEN start_ip and end_ip;
QUERY PLAN
`--SEARCH ipv6_ranges USING INDEX idx_ipv6_ranges_end_ip (end_ip>?)

It looks like it’s just using the end_ip index and not the start_ip index, so maybe it makes sense that it’s slower than the binary search.

I tried to figure out if there was a way to make SQLite use both indexes, but I couldn’t find one and maybe it knows best anyway.

At this point I gave up on the SQLite solution, I didn’t love that it was slower and also it’s a lot more complex than just doing a binary search. I felt like I’d rather keep something much more similar to the binary search.

A few things I tried with SQLite that did not cause it to use both indexes:

  • using a compound index instead of two separate indexes
  • running ANALYZE
  • using INTERSECT to intersect the results of start_ip < ? and ? < end_ip. This did make it use both indexes, but it also seemed to make the query literally 1000x slower, probably because it needed to create the results of both subqueries in memory and intersect them.

attempt 2: use a trie

My next idea was to use a trie, because I had some vague idea that maybe a trie would use less memory, and I found this library called ipaddress-go that lets you look up IP addresses using a trie.

I tried using it here’s the code, but I think I was doing something wildly wrong because, compared to my naive array + binary search:

  • it used WAY more memory (800MB to store just the IPv4 addresses)
  • it was a lot slower to do the lookups (it could do only 100K/second instead of 9 million/second)

I’m not really sure what went wrong here but I gave up on this approach and decided to just try to make my array use less memory and stick to a simple binary search.

some notes on memory profiling

One thing I learned about memory profiling is that you can use runtime package to see how much memory is currently allocated in the program. That’s how I got all the memory numbers in this post. Here’s the code:

func memusage() {
	runtime.GC()
	var m runtime.MemStats
	runtime.ReadMemStats(&m)
	fmt.Printf("Alloc = %v MiB\n", m.Alloc/1024/1024)
	// write mem.prof
	f, err := os.Create("mem.prof")
	if err != nil {
		log.Fatal(err)
	}
	pprof.WriteHeapProfile(f)
	f.Close()
}

Also I learned that if you use pprof to analyze a heap profile there are two ways to analyze it: you can pass either --alloc-space or --inuse-space to go tool pprof. I don’t know how I didn’t realize this before but alloc-space will tell you about everything that was allocated, and inuse-space will just include memory that’s currently in use.

Anyway I ran go tool pprof -pdf --inuse_space mem.prof > mem.pdf a lot. Also every time I use pprof I find myself referring to my own intro to pprof, it’s probably the blog post I wrote that I use the most often. I should add --alloc-space and --inuse-space to it.

attempt 3: make my array use less memory

I was storing my ip2asn entries like this:

type IPRange struct {
	StartIP net.IP
	EndIP   net.IP
	Num     int
	Name    string
	Country string
}

I had 3 ideas for ways to improve this:

  1. There was a lot of repetition of Name and the Country, because a lot of IP ranges belong to the same ASN
  2. net.IP is an []byte under the hood, which felt like it involved an unnecessary pointer, was there a way to inline it into the struct?
  3. Maybe I didn’t need both the start IP and the end IP, often the ranges were consecutive so maybe I could rearrange things so that I only had the start IP

idea 3.1: deduplicate the Name and Country

I figured I could store the ASN info in an array, and then just store the index into the array in my IPRange struct. Here are the structs so you can see what I mean:

type IPRange struct {
	StartIP netip.Addr
	EndIP   netip.Addr
	ASN     uint32
	Idx     uint32
}

type ASNInfo struct {
	Country string
	Name    string
}

type ASNPool struct {
	asns   []ASNInfo
	lookup map[ASNInfo]uint32
}

This worked! It brought memory usage from 117MB to 65MB – a 50MB savings. I felt good about this.

Here’s all of the code for that part.

how big are ASNs?

As an aside – I’m storing the ASN in a uint32, is that right? I looked in the ip2asn file and the biggest one seems to be 401307, though there are a few lines that say 4294901931 which is much bigger, but also are just inside the range of a uint32. So I can definitely use a uint32.

59.101.179.0	59.101.179.255	4294901931	Unknown	AS4294901931

idea 3.2: use netip.Addr instead of net.IP

It turns out that I’m not the only one who felt that net.IP was using an unnecessary amount of memory – in 2021 the folks at Tailscale released a new IP address library for Go which solves this and many other issues. They wrote a great blog post about it.

I discovered (to my delight) that not only does this new IP address library exist and do exactly what I want, it’s also now in the Go standard library as netip.Addr. Switching to netip.Addr was very easy and saved another 20MB of memory, bringing us to 46MB.

I didn’t try my third idea (remove the end IP from the struct) because I’d already been programming for long enough on a Saturday morning and I was happy with my progress.

It’s always such a great feeling when I think “hey, I don’t like this, there must be a better way” and then immediately discover that someone has already made the exact thing I want, thought about it a lot more than me, and implemented it much better than I would have.

all of this was messier in real life

Even though I tried to explain this in a simple linear way “I tried X, then I tried Y, then I tried Z”, that’s kind of a lie – I always try to take my actual debugging process (total chaos) and make it seem more linear and understandable because the reality is just too annoying to write down. It’s more like:

  • try sqlite
  • try a trie
  • second guess everything that I concluded about sqlite, go back and look at the results again
  • wait what about indexes
  • very very belatedly realize that I can use runtime to check how much memory everything is using, start doing that
  • look at the trie again, maybe I misunderstood everything
  • give up and go back to binary search
  • look at all of the numbers for tries/sqlite again to make sure I didn’t misunderstand

A note on using 512MB of memory

Someone asked why I don’t just give the VM more memory. I could very easily afford to pay for a VM with 1GB of memory, but I feel like 512MB really should be enough (and really that 256MB should be enough!) so I’d rather stay inside that constraint. It’s kind of a fun puzzle.

a few ideas from the replies

Folks had a lot of good ideas I hadn’t thought of. Recording them as inspiration if I feel like having another Fun Performance Day at some point.

  • Try Go’s unique package for the ASNPool. Someone tried this and it uses more memory, probably because Go’s pointers are 64 bits
  • Try compiling with GOARCH=386 to use 32-bit pointers to sace space (maybe in combination with using unique!)
  • It should be possible to store all of the IPv6 addresses in just 64 bits, because only the first 64 bits of the address are public
  • Interpolation search might be faster than binary search since IP addresses are numeric
  • Try the MaxMind db format with mmdbwriter or mmdbctl
  • Tailscale’s art routing table package

the result: saved 70MB of memory!

I deployed the new version and now Mess With DNS is using less memory! Hooray!

A few other notes:

  • lookups are a little slower – in my microbenchmark they went from 9 million lookups/second to 6 million, maybe because I added a little indirection. Using less memory and a little more CPU seemed like a good tradeoff though.
  • it’s still using more memory than the raw text files do (46MB vs 37MB), I guess pointers take up space and that’s okay.

I’m honestly not sure if this will solve all my memory problems, probably not! But I had fun, I learned a few things about SQLite, I still don’t know what to think about tries, and it made me love binary search even more than I already did.

Some notes on upgrading Hugo

Warning: this is a post about very boring yakshaving, probably only of interest to people who are trying to upgrade Hugo from a very old version to a new version. But what are blogs for if not documenting one’s very boring yakshaves from time to time?

So yesterday I decided to try to upgrade Hugo. There’s no real reason to do this – I’ve been using Hugo version 0.40 to generate this blog since 2018, it works fine, and I don’t have any problems with it. But I thought – maybe it won’t be as hard as I think, and I kind of like a tedious computer task sometimes!

I thought I’d document what I learned along the way in case it’s useful to anyone else doing this very specific migration. I upgraded from Hugo v0.40 (from 2018) to v0.135 (from 2024).

Here are most of the changes I had to make:

change 1: template "theme/partials/thing.html is now partial thing.html

I had to replace a bunch of instances of {{ template "theme/partials/header.html" . }} with {{ partial "header.html" . }}.

This happened in v0.42:

We have now virtualized the filesystems for project and theme files. This makes everything simpler, faster and more powerful. But it also means that template lookups on the form {{ template “theme/partials/pagination.html” . }} will not work anymore. That syntax has never been documented, so it’s not expected to be in wide use.

change 2: .Data.Pages is now site.RegularPages

This seems to be discussed in the release notes for 0.57.2

I just needed to replace .Data.Pages with site.RegularPages in the template on the homepage as well as in my RSS feed template.

change 3: .Next and .Prev got flipped

I had this comment in the part of my theme where I link to the next/previous blog post:

“next” and “previous” in hugo apparently mean the opposite of what I’d think they’d mean intuitively. I’d expect “next” to mean “in the future” and “previous” to mean “in the past” but it’s the opposite

It looks they changed this in ad705aac064 so that “next” actually is in the future and “prev” actually is in the past. I definitely find the new behaviour more intuitive.

downloading the Hugo changelogs with a script

Figuring out why/when all of these changes happened was a little difficult. I ended up hacking together a bash script to download all of the changelogs from github as text files, which I could then grep to try to figure out what happened. It turns out it’s pretty easy to get all of the changelogs from the GitHub API.

So far everything was not so bad – there was also a change around taxonomies that’s I can’t quite explain, but it was all pretty manageable, but then we got to the really tough one: the markdown renderer.

change 4: the markdown renderer (blackfriday -> goldmark)

The blackfriday markdown renderer (which was previously the default) was removed in v0.100.0. This seems pretty reasonable:

It has been deprecated for a long time, its v1 version is not maintained anymore, and there are many known issues. Goldmark should be a mature replacement by now.

Fixing all my Markdown changes was a huge pain – I ended up having to update 80 different Markdown files (out of 700) so that they would render properly, and I’m not totally sure

why bother switching renderers?

The obvious question here is – why bother even trying to upgrade Hugo at all if I have to switch Markdown renderers? My old site was running totally fine and I think it wasn’t necessarily a good use of time, but the one reason I think it might be useful in the future is that the new renderer (goldmark) uses the CommonMark markdown standard, which I’m hoping will be somewhat more futureproof. So maybe I won’t have to go through this again? We’ll see.

Also it turned out that the new Goldmark renderer does fix some problems I had (but didn’t know that I had) with smart quotes and how lists/blockquotes interact.

finding all the Markdown problems: the process

The hard part of this Markdown change was even figuring out what changed. Almost all of the problems (including #2 and #3 above) just silently broke the site, they didn’t cause any errors or anything. So I had to diff the HTML to hunt them down.

Here’s what I ended up doing:

  1. Generate the site with the old version, put it in public_old
  2. Generate the new version, put it in public
  3. Diff every single HTML file in public/ and public_old with this diff.sh script and put the results in a diffs/ folder
  4. Run variations on find diffs -type f | xargs cat | grep -C 5 '(31m|32m)' | less -r over and over again to look at every single change until I found something that seemed wrong
  5. Update the Markdown to fix the problem
  6. Repeat until everything seemed okay

(the grep 31m|32m thing is searching for red/green text in the diff)

This was very time consuming but it was a little bit fun for some reason so I kept doing it until it seemed like nothing too horrible was left.

the new markdown rules

Here’s a list of every type of Markdown change I had to make. It’s very possible these are all extremely specific to me but it took me a long time to figure them all out so maybe this will be helpful to one other person who finds this in the future.

4.1: mixing HTML and markdown

This doesn’t work anymore (it doesn’t expand the link):

<small>
[a link](https://example.com)
</small>

I need to do this instead:

<small>

[a link](https://example.com)

</small>

This works too:

<small> [a link](https://example.com) </small>

4.2: << is changed into «

I didn’t want this so I needed to configure:

markup:
  goldmark:
    extensions:
      typographer:
        leftAngleQuote: '&lt;&lt;'
        rightAngleQuote: '&gt;&gt;'

4.3: nested lists sometimes need 4 space indents

This doesn’t render as a nested list anymore if I only indent by 2 spaces, I need to put 4 spaces.

1. a
  * b
  * c
2. b

The problem is that the amount of indent needed depends on the size of the list markers. Here’s a reference in CommonMark for this.

4.4: blockquotes inside lists work better

Previously the > quote here didn’t render as a blockquote, and with the new renderer it does.

* something
> quote
* something else

I found a bunch of Markdown that had been kind of broken (which I hadn’t noticed) that works better with the new renderer, and this is an example of that.

Lists inside blockquotes also seem to work better.

4.5: headings inside lists

Previously this didn’t render as a heading, but now it does. So I needed to replace the # with &num;.

* # passengers: 20

4.6: + or 1) at the beginning of the line makes it a list

I had something which looked like this:

`1 / (1
+ exp(-1)) = 0.73`

With Blackfriday it rendered like this:

<p><code>1 / (1
+ exp(-1)) = 0.73</code></p>

and with Goldmark it rendered like this:

<p>`1 / (1</p>
<ul>
<li>exp(-1)) = 0.73`</li>
</ul>

Same thing if there was an accidental 1) at the beginning of a line, like in this Markdown snippet

I set up a small Hadoop cluster (1 master, 2 workers, replication set to 
1) on

To fix this I just had to rewrap the line so that the + wasn’t the first character.

The Markdown is formatted this way because I wrap my Markdown to 80 characters a lot and the wrapping isn’t very context sensitive.

4.7: no more smart quotes in code blocks

There were a bunch of places where the old renderer (Blackfriday) was doing unwanted things in code blocks like replacing ... with … or replacing quotes with smart quotes. I hadn’t realized this was happening and I was very happy to have it fixed.

4.8: better quote management

The way this gets rendered got better:

"Oh, *interesting*!"
  • old: “Oh, interesting!“
  • new: “Oh, interesting!”

Before there were two left smart quotes, now the quotes match.

4.9: images are no longer wrapped in a p tag

Previously if I had an image like this:

<img src="https://jvns.ca/images/rustboot1.png">

it would get wrapped in a <p> tag, now it doesn’t anymore. I dealt with this just by adding a margin-bottom: 0.75em to images in the CSS, hopefully that’ll make them display well enough.

4.10: <br> is now wrapped in a p tag

Previously this wouldn’t get wrapped in a p tag, but now it seems to:

<br><br>

I just gave up on fixing this though and resigned myself to maybe having some extra space in some cases. Maybe I’ll try to fix it later if I feel like another yakshave.

4.11: some more goldmark settings

I also needed to

  • turn off code highlighting (because it wasn’t working properly and I didn’t have it before anyway)
  • use the old “blackfriday” method to generate heading IDs so they didn’t change
  • allow raw HTML in my markdown

Here’s what I needed to add to my config.yaml to do all that:

markup:
  highlight:
    codeFences: false
  goldmark:
    renderer:
      unsafe: true
    parser:
      autoHeadingIDType: blackfriday

Maybe I’ll try to get syntax highlighting working one day, who knows. I might prefer having it off though.

a little script to compare blackfriday and goldmark

I also wrote a little program to compare the Blackfriday and Goldmark output for various markdown snippets, here it is in a gist.

It’s not really configured the exact same way Blackfriday and Goldmark were in my Hugo versions, but it was still helpful to have to help me understand what was going on.

a quick note on maintaining themes

My approach to themes in Hugo has been:

  1. pay someone to make a nice design for the site (for example wizardzines.com was designed by Melody Starling)
  2. use a totally custom theme
  3. commit that theme to the same Github repo as the site

So I just need to edit the theme files to fix any problems. Also I wrote a lot of the theme myself so I’m pretty familiar with how it works.

Relying on someone else to keep a theme updated feels kind of scary to me, I think if I were using a third-party theme I’d just copy the code into my site’s github repo and then maintain it myself.

which static site generators have better backwards compatibility?

I asked on Mastodon if anyone had used a static site generator with good backwards compatibility.

The main answers seemed to be Jekyll and 11ty. Several people said they’d been using Jekyll for 10 years without any issues, and 11ty says it has stability as a core goal.

I think a big factor in how appealing Jekyll/11ty are is how easy it is for you to maintain a working Ruby / Node environment on your computer: part of the reason I stopped using Jekyll was that I got tired of having to maintain a working Ruby installation. But I imagine this wouldn’t be a problem for a Ruby or Node developer.

Several people said that they don’t build their Jekyll site locally at all – they just use GitHub Pages to build it.

that’s it!

Overall I’ve been happy with Hugo – I started using it because it had fast build times and it was a static binary, and both of those things are still extremely useful to me. I might have spent 10 hours on this upgrade, but I’ve probably spent 1000+ hours writing blog posts without thinking about Hugo at all so that seems like an extremely reasonable ratio.

I find it hard to be too mad about the backwards incompatible changes, most of them were quite a long time ago, Hugo does a great job of making their old releases available so you can use the old release if you want, and the most difficult one is removing support for the blackfriday Markdown renderer in favour of using something CommonMark-compliant which seems pretty reasonable to me even if it is a huge pain.

But it did take a long time and I don’t think I’d particularly recommend moving 700 blog posts to a new Markdown renderer unless you’re really in the mood for a lot of computer suffering for some reason.

The new renderer did fix a bunch of problems so I think overall it might be a good thing, even if I’ll have to remember to make 2 changes to how I write Markdown (4.1 and 4.3).

Also I’m still using Hugo 0.54 for https://wizardzines.com so maybe these notes will be useful to Future Me if I ever feel like upgrading Hugo for that site.

Hopefully I didn’t break too many things on the blog by doing this, let me know if you see anything broken!

Terminal colours are tricky

Yesterday I was thinking about how long it took me to get a colorscheme in my terminal that I was mostly happy with (SO MANY YEARS), and it made me wonder what about terminal colours made it so hard.

So I asked people on Mastodon what problems they’ve run into with colours in the terminal, and I got a ton of interesting responses! Let’s talk about some of the problems and a few possible ways to fix them.

problem 1: blue on black

One of the top complaints was “blue on black is hard to read”. Here’s an example of that: if I open Terminal.app, set the background to black, and run ls, the directories are displayed in a blue that isn’t that easy to read:

To understand why we’re seeing this blue, let’s talk about ANSI colours!

the 16 ANSI colours

Your terminal has 16 numbered colours – black, red, green, yellow, blue, magenta, cyan, white, and “bright” version of each of those.

Programs can use them by printing out an “ANSI escape code” – for example if you want to see each of the 16 colours in your terminal, you can run this Python program:

def color(num, text):
    return f"\033[38;5;{num}m{text}\033[0m"

for i in range(16):
    print(color(i, f"number {i:02}"))

what are the ANSI colours?

This made me wonder – if blue is colour number 5, who decides what hex color that should correspond to?

The answer seems to be “there’s no standard, terminal emulators just choose colours and it’s not very consistent”. Here’s a screenshot of a table from Wikipedia, where you can see that there’s a lot of variation:

problem 1.5: bright yellow on white

Bright yellow on white is even worse than blue on black, here’s what I get in a terminal with the default settings:

That’s almost impossible to read (and some other colours like light green cause similar issues), so let’s talk about solutions!

two ways to reconfigure your colours

If you’re annoyed by these colour contrast issues (or maybe you just think the default ANSI colours are ugly), you might think – well, I’ll just choose a different “blue” and pick something I like better!

There are two ways you can do this:

Way 1: Configure your terminal emulator: I think most modern terminal emulators have a way to reconfigure the colours, and some of them even come with some preinstalled themes that you might like better than the defaults.

Way 2: Run a shell script: There are ANSI escape codes that you can print out to tell your terminal emulator to reconfigure its colours. Here’s a shell script that does that, from the base16-shell project. You can see that it has a few different conventions for changing the colours – I guess different terminal emulators have different escape codes for changing their colour palette, and so the script is trying to pick the right style of escape code based on the TERM environment variable.

what are the pros and cons of the 2 ways of configuring your colours?

I prefer to use the “shell script” method, because:

  • if I switch terminal emulators for some reason, I don’t need to a different configuration system, my colours still Just Work
  • I use base16-shell with base16-vim to make my vim colours match my terminal colours, which is convenient

some advantages of configuring colours in your terminal emulator:

  • if you use a popular terminal emulator, there are probably a lot more nice terminal themes out there that you can choose from
  • not all terminal emulators support the “shell script method”, and even if they do, the results can be a little inconsistent

This is what my shell has looked like for probably the last 5 years (using the solarized light base16 theme), and I’m pretty happy with it. Here’s htop:

Okay, so let’s say you’ve found a terminal colorscheme that you like. What else can go wrong?

problem 2: programs using 256 colours

Here’s what some output of fd, a find alternative, looks like in my colorscheme:

The contrast is pretty bad here, and I definitely don’t have that lime green in my normal colorscheme. What’s going on?

We can see what color codes fd is using using the unbuffer program to capture its output including the color codes:

$ unbuffer fd . > out
$ vim out
^[[38;5;48mbad-again.sh^[[0m
^[[38;5;48mbad.sh^[[0m
^[[38;5;48mbetter.sh^[[0m
out

^[[38;5;48 means “set the foreground color to color 48”. Terminals don’t only have 16 colours – many terminals these days actually have 3 ways of specifying colours:

  1. the 16 ANSI colours we already talked about
  2. an extended set of 256 colours
  3. a further extended set of 24-bit hex colours, like #ffea03

So fd is using one of the colours from the extended 256-color set. bat (a cat alternative) does something similar – here’s what it looks like by default in my terminal.

This looks fine though and it really seems like it’s trying to work well with a variety of terminal themes.

some newer tools seem to have theme support

I think it’s interesting that some of these newer terminal tools (fd, cat, delta, and probably more) have support for arbitrary custom themes. I guess the downside of this approach is that the default theme might clash with your terminal’s background, but the upside is that it gives you a lot more control over theming the tool’s output than just choosing 16 ANSI colours.

I don’t really use bat, but if I did I’d probably use bat --theme ansi to just use the ANSI colours that I have set in my normal terminal colorscheme.

problem 3: the grays in Solarized

A bunch of people on Mastodon mentioned a specific issue with grays in the Solarized theme: when I list a directory, the base16 Solarized Light theme looks like this:

but iTerm’s default Solarized Light theme looks like this:

This is because in the iTerm theme (which is the original Solarized design), colors 9-14 (the “bright blue”, “bright red”, etc) are mapped to a series of grays, and when I run ls, it’s trying to use those “bright” colours to color my directories and executables.

My best guess for why the original Solarized theme is designed this way is to make the grays available to the vim Solarized colorscheme.

I’m pretty sure I prefer the modified base16 version I use where the “bright” colours are actually colours instead of all being shades of gray though. (I didn’t actually realize the version I was using wasn’t the “original” Solarized theme until I wrote this post)

In any case I really love Solarized and I’m very happy it exists so that I can use a modified version of it.

problem 4: a vim theme that doesn’t match the terminal background

If I my vim theme has a different background colour than my terminal theme, I get this ugly border, like this:

This one is a pretty minor issue though and I think making your terminal background match your vim background is pretty straightforward.

problem 5: programs setting a background color

A few people mentioned problems with terminal applications setting an unwanted background colour, so let’s look at an example of that.

Here ngrok has set the background to color #16 (“black”), but the base16-shell script I use sets color 16 to be bright orange, so I get this, which is pretty bad:

I think the intention is for ngrok to look something like this:

I think base16-shell sets color #16 to orange (instead of black) so that it can provide extra colours for use by base16-vim. This feels reasonable to me – I use base16-vim in the terminal, so I guess I’m using that feature and it’s probably more important to me than ngrok (which I rarely use) behaving a bit weirdly.

This particular issue is a maybe obscure clash between ngrok and my colorschem, but I think this kind of clash is pretty common when a program sets an ANSI background color that the user has remapped for some reason.

a nice solution to contrast issues: “minimum contrast”

A bunch of terminals (iTerm2, tabby, kitty’s text_fg_override_threshold, and folks tell me also Ghostty and Windows Terminal) have a “minimum contrast” feature that will automatically adjust colours to make sure they have enough contrast.

Here’s an example from iTerm. This ngrok accident from before has pretty bad contrast, I find it pretty difficult to read:

With “minimum contrast” set to 40 in iTerm, it looks like this instead:

I didn’t have minimum contrast turned on before but I just turned it on today because it makes such a big difference when something goes wrong with colours in the terminal.

problem 6: TERM being set to the wrong thing

A few people mentioned that they’ll SSH into a system that doesn’t support the TERM environment variable that they have set locally, and then the colours won’t work.

I think the way TERM works is that systems have a terminfo database, so if the value of the TERM environment variable isn’t in the system’s terminfo database, then it won’t know how to output colours for that terminal. I don’t know too much about terminfo, but someone linked me to this terminfo rant that talks about a few other issues with terminfo.

I don’t have a system on hand to reproduce this one so I can’t say for sure how to fix it, but this stackoverflow question suggests running something like TERM=xterm ssh instead of ssh.

problem 7: picking “good” colours is hard

A couple of problems people mentioned with designing / finding terminal colorschemes:

  • some folks are colorblind and have trouble finding an appropriate colorscheme
  • accidentally making the background color too close to the cursor or selection color, so they’re hard to find
  • generally finding colours that work with every program is a struggle (for example you can see me having a problem with this with ngrok above!)

problem 8: making nethack/mc look right

Another problem people mentioned is using a program like nethack or midnight commander which you might expect to have a specific colourscheme based on the default ANSI terminal colours.

For example, midnight commander has a really specific classic look:

But in my Solarized theme, midnight commander looks like this:

The Solarized version feels like it could be disorienting if you’re very used to the “classic” look.

One solution Simon Tatham mentioned to this is using some palette customization ANSI codes (like the ones base16 uses that I talked about earlier) to change the color palette right before starting the program, for example remapping yellow to a brighter yellow before starting Nethack so that the yellow characters look better.

problem 9: commands disabling colours when writing to a pipe

If I run fd | less, I see something like this, with the colours disabled.

In general I find this useful – if I pipe a command to grep, I don’t want it to print out all those color escape codes, I just want the plain text. But what if you want to see the colours?

To see the colours, you can run unbuffer fd | less -r! I just learned about unbuffer recently and I think it’s really cool, unbuffer opens a tty for the command to write to so that it thinks it’s writing to a TTY. It also fixes issues with programs buffering their output when writing to a pipe, which is why it’s called unbuffer.

Here’s what the output of unbuffer fd | less -r looks like for me:

Also some commands (including fd) support a --color=always flag which will force them to always print out the colours.

problem 10: unwanted colour in ls and other commands

Some people mentioned that they don’t want ls to use colour at all, perhaps because ls uses blue, it’s hard to read on black, and maybe they don’t feel like customizing their terminal’s colourscheme to make the blue more readable or just don’t find the use of colour helpful.

Some possible solutions to this one:

  • you can run ls --color=never, which is probably easiest
  • you can also set LS_COLORS to customize the colours used by ls. I think some other programs other than ls support the LS_COLORS environment variable too.
  • also some programs support setting NO_COLOR=true (there’s a list here)

Here’s an example of running LS_COLORS="fi=0:di=0:ln=0:pi=0:so=0:bd=0:cd=0:or=0:ex=0" ls:

problem 11: the colours in vim

I used to have a lot of problems with configuring my colours in vim – I’d set up my terminal colours in a way that I thought was okay, and then I’d start vim and it would just be a disaster.

I think what was going on here is that today, there are two ways to set up a vim colorscheme in the terminal:

  1. using your ANSI terminal colours – you tell vim which ANSI colour number to use for the background, for functions, etc.
  2. using 24-bit hex colours – instead of ANSI terminal colours, the vim colorscheme can use hex codes like #faea99 directly

20 years ago when I started using vim, terminals with 24-bit hex color support were a lot less common (or maybe they didn’t exist at all), and vim certainly didn’t have support for using 24-bit colour in the terminal. From some quick searching through git, it looks like vim added support for 24-bit colour in 2016 – just 8 years ago!

So to get colours to work properly in vim before 2016, you needed to synchronize your terminal colorscheme and your vim colorscheme. Here’s what that looked like, the colorscheme needed to map the vim color classes like cterm05 to ANSI colour numbers.

But in 2024, the story is really different! Vim (and Neovim, which I use now) support 24-bit colours, and as of Neovim 0.10 (released in May 2024), the termguicolors setting (which tells Vim to use 24-bit hex colours for colorschemes) is turned on by default in any terminal with 24-bit color support.

So this “you need to synchronize your terminal colorscheme and your vim colorscheme” problem is not an issue anymore for me in 2024, since I don’t plan to use terminals without 24-bit color support in the future.

The biggest consequence for me of this whole thing is that I don’t need base16 to set colors 16-21 to weird stuff anymore to integrate with vim – I can just use a terminal theme and a vim theme, and as long as the two themes use similar colours (so it’s not jarring for me to switch between them) there’s no problem. I think I can just remove those parts from my base16 shell script and totally avoid the problem with ngrok and the weird orange background I talked about above.

some more problems I left out

I think there are a lot of issues around the intersection of multiple programs, like using some combination tmux/ssh/vim that I couldn’t figure out how to reproduce well enough to talk about them. Also I’m sure I missed a lot of other things too.

base16 has really worked for me

I’ve personally had a lot of success with using base16-shell with base16-vim – I just need to add a couple of lines to my fish config to set it up (+ a few .vimrc lines) and then I can move on and accept any remaining problems that that doesn’t solve.

I don’t think base16 is for everyone though, some limitations I’m aware of with base16 that might make it not work for you:

  • it comes with a limited set of builtin themes and you might not like any of them
  • the Solarized base16 theme (and maybe all of the themes?) sets the “bright” ANSI colours to be exactly the same as the normal colours, which might cause a problem if you’re relying on the “bright” colours to be different from the regular ones
  • it sets colours 16-21 in order to give the vim colorschemes from base16-vim access to more colours, which might not be relevant if you always use a terminal with 24-bit color support, and can cause problems like the ngrok issue above
  • also the way it sets colours 16-21 could be a problem in terminals that don’t have 256-color support, like the linux framebuffer terminal

Apparently there’s a community fork of base16 called tinted-theming, which I haven’t looked into much yet.

some other colorscheme tools

Just one so far but I’ll link more if people tell me about them:

okay, that was a lot

We talked about a lot in this post and while I think learning about all these details is kind of fun if I’m in the mood to do a deep dive, I find it SO FRUSTRATING to deal with it when I just want my colours to work! Being surprised by unreadable text and having to find a workaround is just not my idea of a good day.

Personally I’m a zero-configuration kind of person and it’s not that appealing to me to have to put together a lot of custom configuration just to make my colours in the terminal look acceptable. I’d much rather just have some reasonable defaults that I don’t have to change.

minimum contrast seems like an amazing feature

My one big takeaway from writing this was to turn on “minimum contrast” in my terminal, I think it’s going to fix most of the occasional accidental unreadable text issues I run into and I’m pretty excited about it.

Some Go web dev notes

I spent a lot of time in the past couple of weeks working on a website in Go that may or may not ever see the light of day, but I learned a couple of things along the way I wanted to write down. Here they are:

go 1.22 now has better routing

I’ve never felt motivated to learn any of the Go routing libraries (gorilla/mux, chi, etc), so I’ve been doing all my routing by hand, like this.

	// DELETE /records:
	case r.Method == "DELETE" && n == 1 && p[0] == "records":
		if !requireLogin(username, r.URL.Path, r, w) {
			return
		}
		deleteAllRecords(ctx, username, rs, w, r)
	// POST /records/<ID>
	case r.Method == "POST" && n == 2 && p[0] == "records" && len(p[1]) > 0:
		if !requireLogin(username, r.URL.Path, r, w) {
			return
		}
		updateRecord(ctx, username, p[1], rs, w, r)

But apparently as of Go 1.22, Go now has better support for routing in the standard library, so that code can be rewritten something like this:

	mux.HandleFunc("DELETE /records/", app.deleteAllRecords)
	mux.HandleFunc("POST /records/{record_id}", app.updateRecord)

Though it would also need a login middleware, so maybe something more like this, with a requireLogin middleware.

	mux.Handle("DELETE /records/", requireLogin(http.HandlerFunc(app.deleteAllRecords)))

a gotcha with the built-in router: redirects with trailing slashes

One annoying gotcha I ran into was: if I make a route for /records/, then a request for /records will be redirected to /records/.

I ran into an issue with this where sending a POST request to /records redirected to a GET request for /records/, which broke the POST request because it removed the request body. Thankfully Xe Iaso wrote a blog post about the exact same issue which made it easier to debug.

I think the solution to this is just to use API endpoints like POST /records instead of POST /records/, which seems like a more normal design anyway.

sqlc automatically generates code for my db queries

I got a little bit tired of writing so much boilerplate for my SQL queries, but I didn’t really feel like learning an ORM, because I know what SQL queries I want to write, and I didn’t feel like learning the ORM’s conventions for translating things into SQL queries.

But then I found sqlc, which will compile a query like this:


-- name: GetVariant :one
SELECT *
FROM variants
WHERE id = ?;

into Go code like this:

const getVariant = `-- name: GetVariant :one
SELECT id, created_at, updated_at, disabled, product_name, variant_name
FROM variants
WHERE id = ?
`

func (q *Queries) GetVariant(ctx context.Context, id int64) (Variant, error) {
	row := q.db.QueryRowContext(ctx, getVariant, id)
	var i Variant
	err := row.Scan(
		&i.ID,
		&i.CreatedAt,
		&i.UpdatedAt,
		&i.Disabled,
		&i.ProductName,
		&i.VariantName,
	)
	return i, err
}

What I like about this is that if I’m ever unsure about what Go code to write for a given SQL query, I can just write the query I want, read the generated function and it’ll tell me exactly what to do to call it. It feels much easier to me than trying to dig through the ORM’s documentation to figure out how to construct the SQL query I want.

Reading Brandur’s sqlc notes from 2024 also gave me some confidence that this is a workable path for my tiny programs. That post gives a really helpful example of how to conditionally update fields in a table using CASE statements (for example if you have a table with 20 columns and you only want to update 3 of them).

sqlite tips

Someone on Mastodon linked me to this post called Optimizing sqlite for servers. My projects are small and I’m not so concerned about performance, but my main takeaways were:

  • have a dedicated object for writing to the database, and run db.SetMaxOpenConns(1) on it. I learned the hard way that if I don’t do this then I’ll get SQLITE_BUSY errors from two threads trying to write to the db at the same time.
  • if I want to make reads faster, I could have 2 separate db objects, one for writing and one for reading

There are a more tips in that post that seem useful (like “COUNT queries are slow” and “Use STRICT tables”), but I haven’t done those yet.

Also sometimes if I have two tables where I know I’ll never need to do a JOIN beteween them, I’ll just put them in separate databases so that I can connect to them independently.

Go 1.19 introduced a way to set a GC memory limit

I run all of my Go projects in VMs with relatively little memory, like 256MB or 512MB. I ran into an issue where my application kept getting OOM killed and it was confusing – did I have a memory leak? What?

After some Googling, I realized that maybe I didn’t have a memory leak, maybe I just needed to reconfigure the garbage collector! It turns out that by default (according to A Guide to the Go Garbage Collector), Go’s garbage collector will let the application allocate memory up to 2x the current heap size.

Mess With DNS’s base heap size is around 170MB and the amount of memory free on the VM is around 160MB right now, so if its memory doubled, it’ll get OOM killed.

In Go 1.19, they added a way to tell Go “hey, if the application starts using this much memory, run a GC”. So I set the GC memory limit to 250MB and it seems to have resulted in the application getting OOM killed less often:

export GOMEMLIMIT=250MiB

some reasons I like making websites in Go

I’ve been making tiny websites (like the nginx playground) in Go on and off for the last 4 years or so and it’s really been working for me. I think I like it because:

  • there’s just 1 static binary, all I need to do to deploy it is copy the binary. If there are static files I can just embed them in the binary with embed.
  • there’s a built-in webserver that’s okay to use in production, so I don’t need to configure WSGI or whatever to get it to work. I can just put it behind Caddy or run it on fly.io or whatever.
  • Go’s toolchain is very easy to install, I can just do apt-get install golang-go or whatever and then a go build will build my project
  • it feels like there’s very little to remember to start sending HTTP responses – basically all there is are functions like Serve(w http.ResponseWriter, r *http.Request) which read the request and send a response. If I need to remember some detail of how exactly that’s accomplished, I just have to read the function!
  • also net/http is in the standard library, so you can start making websites without installing any libraries at all. I really appreciate this one.
  • Go is a pretty systems-y language, so if I need to run an ioctl or something that’s easy to do

In general everything about it feels like it makes projects easy to work on for 5 days, abandon for 2 years, and then get back into writing code without a lot of problems.

For contrast, I’ve tried to learn Rails a couple of times and I really want to love Rails – I’ve made a couple of toy websites in Rails and it’s always felt like a really magical experience. But ultimately when I come back to those projects I can’t remember how anything works and I just end up giving up. It feels easier to me to come back to my Go projects that are full of a lot of repetitive boilerplate, because at least I can read the code and figure out how it works.

things I haven’t figured out yet

some things I haven’t done much of yet in Go:

  • rendering HTML templates: usually my Go servers are just APIs and I make the frontend a single-page app with Vue. I’ve used html/template a lot in Hugo (which I’ve used for this blog for the last 8 years) but I’m still not sure how I feel about it.
  • I’ve never made a real login system, usually my servers don’t have users at all.
  • I’ve never tried to implement CSRF

In general I’m not sure how to implement security-sensitive features so I don’t start projects which need login/CSRF/etc. I imagine this is where a framework would help.

it’s cool to see the new features Go has been adding

Both of the Go features I mentioned in this post (GOMEMLIMIT and the routing) are new in the last couple of years and I didn’t notice when they came out. It makes me think I should pay closer attention to the release notes for new Go versions.

Thoughts on the Resiliency of Web Projects

I just did a massive spring cleaning of one of my servers, trying to clean up what has become quite the mess of clutter. For every website on the server, I either:

  • Documented what it is, who is using it, and what version of language and framework it uses
  • Archived it as static HTML flat files
  • Moved the source code from GitHub to a private git server
  • Deleted the files

It feels good to get rid of old code, and to turn previously dynamic sites (with all of the risk they come with) into plain HTML.

This is also making me seriously reconsider the value of spinning up any new projects. Several of these are now 10 years old, still churning along fine, but difficult to do any maintenance on because of versions and dependencies. For example:

  • indieauth.com - this has been on the chopping block for years, but I haven't managed to build a replacement yet, and is still used by a lot of people
  • webmention.io - this is a pretty popular service, and I don't want to shut it down, but there's a lot of problems with how it's currently built and no easy way to make changes
  • switchboard.p3k.io - this is a public WebSub (PubSubHubbub) hub, like Superfeedr, and has weirdly gained a lot of popularity in the podcast feed space in the last few years

One that I'm particularly happy with, despite it being an ugly pile of PHP, is oauth.net. I inherited this site in 2012, and it hasn't needed any framework upgrades since it's just using PHP templates. My ham radio website w7apk.com is similarly a small amount of templated PHP, and it is low stress to maintain, and actually fun to quickly jot some notes down when I want. I like not having to go through the whole ceremony of setting up a dev environment, installing dependencies, upgrading things to the latest version, checking for backwards incompatible changes, git commit, deploy, etc. I can just sftp some changes up to the server and they're live.

Some questions for myself for the future, before starting a new project:

  • Could this actually just be a tag page on my website, like #100DaysOfMusic or #BikeTheEclipse?
  • If it really needs to be a new project, then:
  • Can I create it in PHP without using any frameworks or libraries? Plain PHP ages far better than pulling in any dependencies which inevitably stop working with a version 2-3 EOL cycles back, so every library brought in means signing up for annual maintenance of the whole project. Frameworks can save time in the short term, but have a huge cost in the long term.
  • Is it possible to avoid using a database? Databases aren't inherently bad, but using one does make the project slightly more fragile, since it requires plans for migrations and backups, and 
  • If a database is required, is it possible to create it in a way that does not result in ever-growing storage needs?
  • Is this going to store data or be a service that other people are going to use? If so, plan on a registration form so that I have a way to contact people eventually when I need to change it or shut it down.
  • If I've got this far with the questions, am I really ready to commit to supporting this code base for the next 10 years?

One project I've been committed to maintaining and doing regular (ok fine, "semi-regular") updates for is Meetable, the open source events website that I run on a few domains:

I started this project in October 2019, excited for all the IndieWebCamps we were going to run in 2020. Somehow that is already 5 years ago now. Well that didn't exactly pan out, but I did quickly pivot it to add a bunch of features that are helpful for virtual events, so it worked out ok in the end. We've continued to use it for posting IndieWeb events, and I also run an instance for two IETF working groups. I'd love to see more instances pop up, I've only encountered one or two other ones in the wild. I even spent a significant amount of time on the onboarding flow so that it's relatively easy to install and configure. I even added passkeys for the admin login so you don't need any external dependencies on auth providers. It's a cool project if I may say so myself.

Anyway, this is not a particularly well thought out blog post, I just wanted to get my thoughts down after spending all day combing through the filesystem of my web server and uncovering a lot of ancient history.
