How I failed to make a game: Raycasting on the GBA
Today I am releasing my raycasting tech demo for the GameBoy Advance. Although it falls short of the goals I set out in the beginning – which included releasing a playable game –, I think there are some lessons worth sharing with the world.

CRLF is obsolete and should be abolished
It seems that (1) there is still more software in circulation that depends on archaic CRLF line endings than I originally thought and (2) many people do not share my enthusiasm for creating a CRLF-free world. Alas. This makes me sad, but it is what it is. Thanks to everyone who was willing to give the idea a test run…

Defining Statistical Models in Jax?
This is Bob. And I’d like to know the best way for us to code a bunch of models in JAX to use to evaluate parallel algorithms including normalizing flows. I’m going to dump out my current thinking, but I’m really hoping to get feedback from experts on the best way to do this without starting a flame war in the…

Lessons learned from profiling an algorithm in Rust
Recently, I've been working on a new approximate nearest neighbor search algorithm called RaBitQ . The author has already provided a C++ implementation that runs quite fast. I tried to rewrite it in Rust (yet another RiiR). But I found that my implementation is much slower than the original one. Here is how I improve…

Exploring Typst, a new typesetting system similar to LaTeX
In this article, we explore Typst, a new typesetting system similar to LaTeX. We explore its syntax, current uses and possible uses; we test its scripting system, which is incredibly powerful; we compare it with LaTeX, Markdown and Word, which can be used in similar roles; and we explore its applicability to the task…

A dictionary of single-letter variable names
Haskell’s expressive type system means that type signatures can carry a lot of information. Haskell’s polymorphism means that you sometimes write functions that work across an enormous range of types, and are left wondering “what do I actually call my variables?”. It is often the case that there’s nothing to say…

Started a guide to writing FUSE filesystems in Python
As DebConf22 was coming to an end, in Kosovo, talking with Eeveelweezel they invited me to prepare a talk to give for the Chicago Python User Group . I replied that I’m not really that much of a Python guy… But would think about a topic. Two years passed. I meet Eeveelweezel again for DebConf24 in Busan, South Korea…
