How I Program in 2024
I talk a lot here about using computers freely , how to select programs to use, how to decide if a program is trustworthy infrastructure one can safely depend on in the long term. 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…

Porting my JavaScript game engine to C for no reason
tl;dr: high_impact is small game engine for 2D action games. It's written in C, compiles to Windows, Mac and Linux as well as to WASM for the Web. It's “inspired by” my original Impact JavaScript game engine from 2010. The name high_impact is a nod to a time when C was considered a high level language.

Primitive Recursive Functions for a Working Programmer
Programmers on the internet often use Turing-completeness terminology. Typically, not being Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most such discussions are misinformed --- that not being Turing complete doesn't actually mean what folks want it to mean, and is…

Programming a CH32v003 with light
A comedic example, parked nicely on the thinnest wedge of the venn diagram, is the HamFurs – people who do amateur radio while wearing fur suits. While it isn't my cup of tea, I love that such a group exists. They seemed like nice people when I chatted to them.

Building static binaries with Go on Linux
One of Go's advantages is being able to produce statically-linked binaries [1] . This doesn't mean that Go always produces such binaries by default, however; in some scenarios it requires extra work to make this happen. Specifics here are OS-dependent; here we focus on Unix systems.

Crafting Interpreters with Rust: On Garbage Collection
I became interested in implementing programming languages a few years ago and discovered [Crafting Interpreters](https://craftinginterpreters.com/) by Bob Nystrom. At the time, I had experience with Rust and decided to use it to follow the book. Albeit, being a noob, I managed to implement a fully functional bytecode…

Higher-kinded bounded polymorphism in OCaml (2021)
How bounded higher-kinded polymorphism arises in practice, and how to express it in OCaml, in several different ways. Some ways are rather concise -- but less widely known.

tolower() with AVX-512
A couple of years ago I wrote about tolower() in bulk at speed using SWAR tricks . A couple of days ago I was interested by Olivier Giniaux’s article about unsafe read beyond of death , an optimization for handling small strings with SIMD instructions, for a fast hash function written in Rust.

Bril: An Intermediate Language for Teaching Compilers
I created a new intermediate language, called Bril, for teaching my funky open-source, hands-on compilers course. Because it’s for education, Bril prioritizes simplicity and regularity over more typical compiler priorities like performance and concision. This is an overview of Bril’s design, its quirks, and the…
