Since Chromium 148, Math.tanh is now fingerprintable to link underlying OS
Math.tanh, every CSS trig function, and the Web Audio compressor all route through the host libm, so the rounding of a cosine betrays the OS a browser actually …

Today I Rescued 7,234 Old GIFs
As Web standards have moved on, a particular 1990s library of GIFs has been hard to effectively archive and was at risk of being lost forever. So I swooped in, wrote some hacky code, and now a few thousand low-res images have been saved for posterity. Hurrah, I guess?

I love LLMs, I hate hype
I think from this blog you may misunderestimate how absolutely giddy I am about AI. I did hacking from 2007-2014, after that my whole career has been devoted to AI. I love the progress. I’m so excited for the new LLMs, self driving cars, video generation models, and coding agents. I set up a Linux box with opencode on…

Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k
Claude Code vs OpenCode token overhead measured at the API boundary. Out-of-the-box baselines, instruction file weight, MCP schema tax, subagent multipliers, and cache-write behaviour.

Teardown: A Generic 7-Port USB 3.0 Hub That Wasn't
The recent end-of-financial-year sales were rather interesting – I found myself spending a lot more time browsing AliExpress than I did Amazon or eBay this year which is something I wouldn…

Against Usefulness
In a Brooklyn warehouse, a man handed me a piece of paper that was a running computer program.

Migrating a production AI agent to GPT-5.6: 2.2x faster, 27% cheaper
For four months, no frontier model beat Claude Opus in our production evals. GPT-5.6 did. This is what we learned while migrating.

Don't you mean extinct?
In 1993, Jurassic Park came out and revolutionized the use of CGI in films [1] . To the public the experience was magic. But for some of the people in the movie industry, it was a rude awakening.

Making Crash Bandicoot (2011)
In the summer of 1994 Naughty Dog, Inc. was still a two-man company, myself and my longtime partner Jason Rubin. Over the preceding eight years, we had published six games as a lean and mean duo, b…

Old and new apps, via modern coding agents
I have been interested in machine-assisted ways to do and teach mathematics from as far back as 1999, when I started coding several applets in Java 1.0, both for my complex analysis and linear alge…

AI 2040 and the cult of intelligence
I used to be one of these people. I read Yudkowsky and was like, OMG recursive self improvement hard takeoff AI is coming. Then I joined the real world and actually tried to do things. At comma, we ship a hardware product of similar complexity to a cell phone, and it’s really hard. Reality has lots of finicky details…

Prefer strict tables in SQLite
I prefer strict tables in SQLite because they avoid some datatype problems, such as putting text in number columns.

Reverse centaurs are the answer to the AI paradox (2025)
My latest Locus column is "Reverse Centaurs," and it sets out to unravel a paradox: how is it that some AI's users describe their experience as a hellish ordeal, while others delight in the ways that AI is changing their lives for the better?

Nvidia, CoreWeave, and Nebius: Inside the Circular Financing of the GPU Boom
Neoclouds are one of the more hotly debated AI business models, with CoreWeave and Nebius being the two most widely recognized names. These companies have seen their sales, backlog, and share prices soar. Yet, supporting their growth is extremely expensive, and neoclouds do not have the same cash nor operating cash…

We scaled PgBouncer to 4x throughput
PgBouncer is single-threaded, so a single process caps out at one CPU core no matter the box size. See how ClickHouse Managed Postgres runs a peered fleet of PgBouncer processes with so_reuseport to scale pooling across every core — with benchmarks showin

Your code is fast if you're lucky
Recently, while working on an optimized Quicksort implementation, I came across a rather interesting quirk. Modern compilers (especially Clang) optimize loops using fast, branch-free instructions - provided you use the right programming style.

The kids with phones are alright
T here was a remarkable video going around the Scottish socials yesterday which led to quite a bit of media coverage . It’s a four-minute long video showing some furious Scotrail passengers confronting a drunk middle-aged pervert who is quietly filming a group of quiet, sober 16- and 17-year old girls heading home…

Your 'app' could have been a webpage (so I fixed it for you)
I was asked to install a mobile app to get access to the itinerary of a trip to Disneyland I'm taking with the kids. Fuck that noise: couldn't it have just been a Web page? An hour of reverse-engineering later, it is, and it's superior in virtually every way to the "app" that it replaces.

The zero-cost fallacy: open-source software in the agentic era
Open source software is the foundation of much of our digital infrastructure. However, is AI undermining the incentive structure? What needs to change?
