A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t
The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more

I find blockchain fascinating because it extends open source software development to open source + state. This seems to be a genuine/exciting innovation in computing paradigms; We don’t just get to share code, we get to share a running computer, and anyone anywhere can use it in an open and permissionless manner. The seeds of this revolution arguably began with Bitcoin, so I became curious to dril
This is an all-in-one crosspost of a scenario I originally published in three parts on my blog, No Set Gauge.

The Atrocious State Of Binary Compatibility on Linux and How To Address It. By Dale Weiler GitHub Time To Read: ~30 Minutes Last Updated: Monday, March 17th 2025 Summary Linux binary compatibility is plagued by one thing that is often overlooked when evaluating shipping software on Linux. This article will deconstruct how to arrive to that conclusion, how to address it when shipping software today
Flatpak Is Not the Future
← ludocode.com Flatpak Is Not the Future Original date: 2021-11-18 Last updated: 2021-11-23 Deploying apps for the Linux desktop is hard. A major problem has historically been library compatibility. Different Linux distributions, and even different versions of the same distribution, have had incompatible libraries. Unfortunately, there hasn’t always been a culture of backwards compatibility on the
