The messy reality of SIMD (vector) functions
We’ve discussed SIMD and vectorization extensively on this blog, and it was only a matter of time before SIMD (or vector) functions came up. In this post, we explore what SIMD functions are, when they are useful, and how to declare and use them effectively. A SIMD function is a function that processes more than… Read

Prompting LLMs is not engineering
prompt engineering is nothing but an attempt to reverse-engineer a non-deterministic black box for which any of the parameters below are unknown: - training set - weights - constraints on the model - layers between you and the model that transform both your input and the model's output that can change at any time …

Locality of Behaviour (2020)
Carson Gross explores the Locality of Behaviour (LoB) principle, which emphasizes making the behavior of code units obvious on inspection to enhance maintainability. He discusses the tradeoffs between LoB and other software design principles like DRY and SoC, offering insights on balancing clarity, abstraction, and…

Baba Is Eval
Baba is You is a sokoban puzzle game where the rules themselves have to be manipulated to win. (For the uninitiated, the store page should explain the idea best.) The level of abstraction required to solve most levels makes it a formidable reasoning benchmark, with many reasoning steps being completely orthogonal to…

I scanned all of GitHub's "oops commits" for leaked secrets
GitHub Archive logs every public commit, even the ones developers try to delete. Force pushes often cover up mistakes like leaked credentials by rewriting Git history. GitHub keeps these dangling commits, from what we can tell, forever. In the archive, they show up as “zero-commit” PushEvents.

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
I've always been told that caching is a tool to make software faster. That, given some careful considerations to consistency, caching makes it so that when...

Writing Code Was Never the Bottleneck
LLMs make it easier to write code, but understanding, reviewing, and maintaining it still takes time, trust, and good judgment.

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…

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 .
