Super Mario Derivations
One of the most surprising aspects of the Nix language is that it is lazy, especially if you have never used a lazy language before. This laziness is what makes much of Nixpkgs possible, and its complexity.

An Apology
We launched an AirTag silencing tool recently. We have always made products we want for ourselves, and this was no different - we wanted it for AirTags on our bikes. (Some of us here have bikes more valuable than our cars.) In retrospect though, this also has the side effect of aiding someone with bad intentions to tra

A look under our trunk: what's in our compute
Compute is the brain of the Waymo Driver, translating raw sensor data into real-time driving commands. Operating demonstrably safe, physical AI on the road demands a fundamental shift towards a system engineered for deterministic, low-latency performance. Over the past decade, we have co-designed our hardware…

Making your own programming language is easier than you think (but also harder)
In mid-December last year I started making my own programming language. It's waaay far from any production quality yet (though I did manage to write a working 1k LOC Monte-Carlo path tracer in it), but the project is on pause right now, so I figured it's a good time to write something about it.

Automating AI Away
A. Karpathy once said that OpenAI researchers are effectively "automating themselves away" by improving their AI. Right now I develop Beagle SCM with Anthropic's Fable and it is of course a brilliant model able to spot nits in a mountain of code, file tickets, make fixes. Still, yesterday it managed to commit the…

Remarkable Pro Colors
I was happy with the Remarkable 2 and when the Remarkable Pro came out I decided to go with a second one in order to be able to see two pages at once : one as a reference for reading and one for writing, as one would normally do with paper. Expensive approach, I know.

The way CTRL-C in Postgres CLI cancels queries is incredibly hack-y
There are a few different reasons to hit the brakes on a Postgres query. Maybe it’s taking too long to finish. Maybe you realised you forgot to create an index that will make it orders of magnitude quicker. Maybe there’s some reason the results are no longer needed. Or maybe you, or your LLM buddy, […]

A 3D Body from Eight Questions – No Photo, No GPU
We trained an MLP that predicts 58 body shape parameters from 8 questionnaire inputs. The trick: a differentiable physics loss. Mass accuracy: 0.3 kg mean vs 3.9 kg for Ridge. No GPU at inference.

Why I don't think AGI is imminent
The CEOs of OpenAI and Anthropic have both claimed that human-level AI is just around the corner — and at times, that it's already here. These claims have generated enormous public attention. There has been some technical scrutiny of these claims, but critiques rarely reach the public discourse. This piece is a sketch…

More than half of adults in U.S. say they lack basic statistical understanding

The UK government's Low Value Purchase System is a waste of time
It can be hard running a small business. If you want to sell to a large organisation like the UK Government, there are forms to fill in, checks to comply with, tenders to bid on, and a hundred other things. Luckily, there's the RM6237 Low Value Purchase System to make everything better. If a department wants to buy…

2004 RuneScape fit a multiplayer RPG into 56k dial-up
In 2004 I played too much RuneScape on a 56k modem that died the moment Mum picked up the phone. A 3D world, up to a couple of thousand players on a server, dozens on screen at once - in the browser, on 5 kilobytes per second. It worked. Let’s follow a single step and see how.
