Reverse-engineering the 1998 Ultima Online demo server
After 10 years of on-and-off work, I’m releasing a full reverse-engineering of the 1998 Ultima Online demo server: https://github.com/draxinar/ouo . About 5,000 functions disassembled from MSVC x86 and translated into portable C99, with each function compared instruction-by-instruction against the binary.

Hand Drawn QR Codes (2025)
I really like QR codes. Recently I purchased a new sticky-note-like pad from a new local stationery store in Minneapolis. The sheets have a 10x10 grid and 2x10 grid. I knew what I wanted to...

I am worried about Bun
Bun is excellent software. Anthropic owns it now, Bun sits under Claude Code, and Claude Code getting worse makes me worried Bun could follow the same enshittification path.

The 'Hidden' Costs of Great Abstractions
In the world of computing, we tend to abstract away complexity. Doing so seems liberating. It enables us to focus on the bigger picture. Unfortunately, in doing so, the fidelity of our understanding often decreases. We sometimes end up blinding ourselves.

Good developers learn to program. Most courses teach a language
A bootcamp can teach you the syntax of a language in six weeks. The part that takes a decade is everything else: where the seams go, where the data flows, which decisions you are stuck with for the life of the codebase. This is a senior developer's argument for what learners should actually be looking for, after…
