- Over the past few months it’s become clear that coding agents are extraordinarily good at building a weird version of a “clean room” implementation of code. The most famous version …

- There is a trick that is spreading through social media. If you block the claude user on GitHub, then each time you visit a GitHub repository that has commits by this user you get a banner at the top alerting you of the user's participation. It's an easy way to spot projects...
- There are a lot of prime classes, such as left truncating primes, twin primes, mersenne primes, palindromic primes, emirp primes and so on. The Wikipedia page on primes lists many more. Recently I got to thinking (as one is wont to do) how difficult would it be to come up with a...

- All You Need is Specs? Today I’m releasing whenwords, a relative time formatting library that contains no code. whenwords provides five functions that convert between timestamps and human-readable strings, like turning a UNIX timestamp into “3 hours ago”. There are many...
- One of the core design points of Pystd has been that it maintains perfect API and ABI stability while also making it possible to improve the code in arbitrary ways. To see how that can be achieved, let's look at what creating a new "year epoch" looks like. It's quite simple....

- Happy new year! 🎉 For an upcoming project on the blog requiring many video-game sprites I've created a small tool (“sugarcookie”) using the always-lovely Python image-processing library Pillow. This tool takes a spritesheet and a list of mask colors, a minimum size, and then...
- With no surprise the end of one year marks the start of the next. But managing a good working environment on macOS has long been a game of “hope for the best.” We’ve all been there: a curl | sh here, a manual brew install there, and six months later, you’re staring at a broken...
