Let's write a video game from scratch like it's 1987
In a previous article I've done the 'Hello, world!' of GUIs in assembly: A black window with a white text, using X11 without any libraries, just talking directly over a socket.

Probably pay attention to tokenizers
Last week I was helping a friend of mine to get one of his new apps off the ground. I can’t speak much about it at the moment, other than like most apps nowadays it has some AI sprinkled over it. Ok, maybe a bit maybe more just a bit – depends on the way you look at it, I suppose. There is a Retrieval-augmented…

Using S3 as a Container Registry
For the last four months I’ve been developing a custom container image builder, collaborating with Outerbounds1. The technical details of the builder itself might be the topic of a future article, but there’s something surprising I wanted to share already: you can use S3 as a container registry! You heard it right…

A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from…

The Championnats d’Europe d’Escalade (climbing) in Villars-sur-Ollon has just finished. I couldn’t make it to all the events, but did see the finals of the “Speed” event. It’s a series of head-to-head elimination races up a 15m tall wall, resulting in an eventual victor after enough rounds.

I also spend my time building such infrastructure, because there isn't a lot of it out there. As I do so, I'm always acutely aware that I'm…

Breaking down tasks
Something missing from this series on estimation, until now, has been a discussion of how to “break down” a project into a well-defined task list. I’d not previously written about this because, to me, it’s largely intuitive. But it isn’t for everyone, so this post fills the gap, and explains in detail how I break down…

Writing a TrueType font renderer
Text is the medium of digital interaction, and text rendering has an outsized impact on the overall fit and finish of any system. It therefore pains me that axle has for years relied on a low-resolution 8x8 bitmap font. Let’s fix it! Take a look at the characters composing this sentence. Note the curves, the negative…

EU: Users who refuse scanning to be prevented from sharing photos and links
The highly controversial indiscriminate child sexual abuse regulation (so-called chat control) could still be endorsed by EU governments after all, as France could give up its previous veto.
