For most of the seventeenth century, Amsterdam kept catching fire. It was the richest city on earth, which meant its houses were stuffed with curtains and furnishings and its warehouses with tar, hemp, rope, sugar and spices. Then, in the 1680s, the city government beat fire almost completely. From 1682 to 1687, fire losses were under one percent of what they had been in the twelve years before. worksinprogress.co/issue/how-amst… Part of the credit belongs to a new fire engine. In 1672, the painter Jan van der Heyden designed a much better machine, with a leather suction hose, the first long, flexible delivery hose, and an air chamber that produced a continuous, high-pressure stream. But the real story is one of better institutions. In 1681, the city's merchant government passed new firefighting regulations. These professionalized some aspects of the service, establishing district companies consisting of thirty-six conscripted residents under two fire master and a network of professional trumpeters who sat in towers and sounded the alarm. The regulations created new incentives: under the new rules, lamplighters who reported fires and the first three fire companies to arrive at a blaze received cash prizes, while watchmen who failed to notify firefighters and homeowners who fought a fire themselves before raising the alarm were given fines. Amsterdam's citizens were known throughout Europe for gladly paying high taxes, and encouraging a culture of 'useful invention'. In the case of firefighting, they certainly got their money’s worth. New from @vpostrel in Works in Progress.

@willsolfiac UPI is supported by Apple Pay and Google Pay in India and I think if you have those you've basically won. It's a real fail for Open Banking that it hasn't had something similar - I presume b/c of lack of functionality rather than lack of interest. As you say, the savings are big.

@s8mb Yeah I guess there's no technical reason why bank to bank couldn't be enabled via QR code as in other countries, like say Monzo's money transfer feature. Personally I prefer using a physical card, but I think most people pay with their phone now anyway.

I had no idea that Brazil has its own central bank-created payments system, used by over 80% of the population, where merchants pay 0.33% per transaction, compared to 1%-4% for Visa / Mastercard / Amex. If a government can save its businesses a few percent per transaction, and keep the fees in-country, why wouldn't they do it?

@londinburgh Yes, and I think the actual policies needed to end rough sleeping – large-scale private housebuilding plus incarcerations, institutionalisations and deportations – are unlikely to be options the current govt is willing to consider.

@s8mb It's also one of those problems we're politicians need to use a little discretion when intepreting the public's stated preference. When they say they don't want to see beggars on the streets, they don't mean that the state should be even more generous with them.

"End rough sleeping" is very "Maths to 18". We keep getting mid-term PMs who think people want them to pursue their personal agendas, when they're actually being hired as stand-ins to solve problems that their predecessors couldn't.

@willsolfiac I think the "rails" are the same (ie both do bank to bank payments), OB may just not be fully-featured enough to compete. In my experience most of the things holding OB back are some combination of anti-fraud and opposition by banks to the loss of interchange. Very annoying.

@dc_lawrence It's a nice policy objective, as is improving young people's maths, but it's not a central mission of a government that the public has voted for.

Housing shortages drive rough sleeping by making spare bedrooms scarcer, which makes it harder for people in crisis (drugs, abusive relationships, mental health) to stay with someone who cares for them. Britain has some of the smallest homes in Western Europe. worksinprogress.co/issue/why-hous…

I’m staggered that Burnham has promised to end rough sleeping across the country. It was his biggest promise when he became mayor of Greater Manchester and he didn’t come close. Here are the numbers, as revealed by @ManchesterMill last month.

Why do Americans think their national anthem sounds good when sung by a singer doing the most intense sounds she possibly can, with no melody whatsoever?

I mostly agree with his post but I think the question is the extent to which Chinese labs are appropriating US labs’ innovations, not the price at which they sell their models. If they were bearing the full cost of developing their models and then releasing them for free that would be fine from an innovation perspective, although them being able to do so over a long time frame would imply frightening things about Chinese labs’ capabilities or that they were being subsidised to do predatory pricing in ways we would likely want to respond to.

Some observations on Kimi: 1. It's a very good model! I don't think its performance can be explained away by distillation or anything like that. In agentic coding sessions, it seems pretty much on par with the best public models of Q1 2026. In my fairly limited use, it also seemed very token hungry. It's not obvious to me that this model is actually that cheap to run. 2. I am personally surprised the Chinese state continues to allow the open sourcing of models this good, given potential risks. To be clear, I *myself* might be fine with models presenting this level of marginal risk being open weight, but I am surprised that China is fine with it. I suspect the reason they are is 75% explained by strategic blindness/lack of AGI-pilledness (the CCP is very Yann Lecun-y in its views of AI). The other 25% or so is their lack of compute for customer inference (making China's open-weight strategy an unintended byproduct of US export controls) and the normal Chinese strategy of aggressive exports. For the companies, as opposed to the government, the decision to open source is partially ideological and partially because they are behind, and they know that very few people would pay for sub-frontier models from China. 3. Open-weight models are inherently decelerationist, and I'm continually surprised to see the so-called "accelerationists" so excited about open-weight models. I suspect the reason they are is that they know open-weight models are effectively ungovernable, and they simply like the overall cloak of ungovernability open-weight models create over the whole of AI. It's not a bad strategy; it reminds me of James Scott's recounting of the hill people in "the art of not being governed." Still, in the end, open-weight models deter further AI capex. 4. One probable outcome of an open-weight-model-dominant world is full AI communism, which is precisely what China proposes: rather than a market product, AI is a "public good" which will ultimately be provided by the state as a kind of "digital public infrastructure." This future strikes me as a dystopian hellscape, but I've never met an open-weight models advocate who doesn't ultimately concede this is where things end. You'd be surprised how many 'accelerationists' lobbied me, while I was in government, to support an eleven or twelve-figure federally funded data center so that startups could train models at a subsidy and then give them away for free. There was no other way for AI to progress, they said. Perhaps this is the logical end state of things. Nonetheless, I find myself surprised to see supposed accelerationists excited about such an outcome. I think many of them just don't know what they're doing. Many accelerationists do not view the creation and serving of frontier models as a legitimate business. 5. I would guess that the Trump Administration will at some point realize that their best strategy here would be to create large amounts of regulatory risk around the use of open-weight Chinese models. You don't need to "ban open source" (one of the dumber motifs of AI policy discussion). You just need to direct every agency to issue soft law that creates FUD. "A Federal Reserve Advisory Bulletin found that there may be backdoors in Chinese AI models." It needn't be that well justified. You just create enough regulatory risk that every regulated enterprise backs off. You probably don't want to create so much regulatory risk that you scare off the hyperscalers from serving Chinese models; this will just drive startups to sketchier providers. There's a happy middle ground here. I'd assume they will do some version of this. 6. It's probably true that open-weight models of this capability make the world a bit more dangerous, but not so much more that you'll really notice. At some point the models will be capable enough that you will notice. "A nonliving, invisible, dangerous, and infinitely self-replicating agent escaped from a Chinese lab," you say? Color me shocked.

@MarcWarner10 It is really frustrating how difficult it is for people in govt to grasp this “obliquity”. If, for example, you want low prices in energy, you should tell the regulator to focus on competition and access, not give it a mandate to keep prices low!

@v_j_freeman I softly disagree. FS is basically a non-job these days but is prestigious enough to give to someone you can’t just sack. Miliband can do much less damage there than in Energy or HMT.

Ed M prides himself on being unyielding, he lacks social skills unless dealing with full ideological allies, & being FS is all about dealing smoothly with leaders you could be at significant odds with politically. He’s set up to fail.

@s8mb I think it’s worth adding here that I run this Claude terminal session specifically in my Obsidian vault, which syncs ancross all devices. More serious editing can therefore be done on the iPad without needing the weight of a laptop.

The iPad/tablet has never been a good bridge between the phone and laptop, but Claude Code and Codex parts of their respective iOS apps are genuinely starting to change that.

People often evaluate Pangram's false positive rate using pre-ChatGPT text. This is where our 1 in 10,000 FPR number comes from. But we often face the question: "How can you prove that Pangram isn't just memorizing pre-2022 text that's already in its training set?" To some degree, this is a fair criticism. If you're checking Moby Dick, any pretrained base will have seen this text, and therefore could have memorized that this text is human-written. I talked to someone who wanted to test this hypothesis by testing Pangram on tokens that didn't exist on the internet. Super interesting. Of course we want to see the results. So I gave them credits, they found a bunch of old books that didn't exist anywhere, and scanned them. Almost three million words in total. What they found was actually quite interesting! Three AI-assisted segments and one AI-generated segment. But when they looked at their data, they found that it the segments Pangram flagged were actually hallucinated by Mistral OCR. Mistral OCR had hallucinated entire tables onto blank pages, and these were the only segments that Pangram flagged as AI. No false positives in about three million words / 8,000 segments. Pretty cool!
