Why does an extraneous build step make my Zig app 10x faster?
For the past few months, I’ve been curious about two technologies: the Zig programming language and Ethereum cryptocurrency. To learn more about both, I’ve been using Zig to write a bytecode interpreter for the Ethereum Virtual Machine. Zig is a great language for performance optimization, as it gives you fine-grained…

Regex character "$" doesn't mean "end-of-string"
This article is about a bit of surprising behavior I recently discovered using Python's regex module (re) while developing SBOM tooling for CPython. Folks who've worked with regular expressions be...

Let's create a Tree-sitter grammar
One of my favorite features in Neovim is the Tree-sitter integration. It allows for fast syntax highlighting that works well even in an error state (often the case when you’re editing code), and it has additional semantics (you can differentiate between function parameters and local variables).

I wrote a new JIT compiler for PostgreSQL
Sometimes, I don’t know why I do things. It’s one of these times. A few months ago, Python 3.13 got its JIT engine, built with a new JIT compiler construction methodology (copy-patch, cf. research paper ). After reading the paper, I was sold and I just had to try it with PostgreSQL. And what a fun ride it’s been so…

What part of Rust compilation is the bottleneck?
Rust compilation times is an ongoing topic that generates many discussions online1. Most people don’t really care about what exactly takes time when compiling Rust program; they just want it to be faster in general. But sometimes, you can see people pointing fingers at specific culprits, like LLVM or the borrow…

Reversing for dummies – x86 assembly and C code (Beginner/ADHD friendly)
Before I got into reverse engineering, executables always seemed like black magic to me. I always wondered how stuff worked under the hood, and how binary code is represented inside .exe files, and how hard it is to modify this ‘compiled code’ without access to the original source code.
