Code-GUI bidirectional editing via LSP
I built a small proof-of-concept for a system that enables real-time bidirectional editing between any modern code editor and a GUI, enabled by an LSP1 server. Code-based CAD I like working on small projects at home that benefit from CAD. I’m also a programmer with a personal development environment that I’ve spent…

Caching is an abstraction, not an optimization

The original LZEXE (A.K.A. Kosinski) compressor source code has been released
Last year, I discovered that the Kosinski compression format is actually LZEXE, which was used for compressing DOS executables back in the 90s and the late 80s. Its developer catalogues three versi…

I write type-safe generic data structures in C
See my follow-up article: “A Fast, Growable Array With Stable Pointers in C” I write type safe generic data structures in C using a technique that I haven’t seen elsewhere1. It uses unions to associate type information with a generic data structure, but we’ll get to that. My approach works for any type of data…

Donkey Kong Country 2 and Open Bus
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

The story of Max, a real programmer
This is a story about Imagebin. Imagebin is the longest-lived software project that I still maintain. I'm the only user. I use it to host images, mainly to include in my blog, sometimes for sharing in other places. Imagebin's oldest changelog entry is dated May 2010, but I know it had already existed for about a year…

The Evolution of Caching Libraries in Go
For the last few years, I've been developing caching library, and today I'd like to talk about the evolution of caches in Go and where we stand today. Especially since Go 1.24 was officially supposed to focus on caching improvements, but I haven't heard much news about them - time to fix that .

Weird Expressions in Rust
Rust has a very powerful type system, but as a result it has some quirks, some would say cursed expressions. There’s a test file, weird-expr.rs , in the rust repository that tests for some of these and makes sure there consistent between updates. So I wanted to go over each of these and explain how it’s valid rust.

Parameterized types in C using the new tag compatibility rule
C23 has a new rule for struct, union, and enum compatibility finally appearing in compilers starting with GCC 15, released this past April, and Clang later this year. The same struct defined in different translation units (TU) has always been compatible — essential to how they work. Until this rule change, each such…
