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…

If I could make my own GitHub
My friend and I have a game where we talk about what we'd do if we were rich. Not rich like 'paid off the mortgage' rich. Rich like a man who owns a submarine he's never been inside. Rich like a man whose third wife has a skincare

Should I run plain Docker Compose in production in 2026?
Yes, plain Docker Compose can still run production workloads in 2026, but only if you close the operational gaps it leaves: cleanup, healing, image pinning, socket security, and updates.

Functional programmers need to take a look at Zig

Why I still reach for Lisp and Scheme instead of Haskell
Scheme (and Lisp) lets you express complex systems and problem domains in simpler terms than any other language can. For all its brilliance, Haskell resists most of the attempts people make to just hack and write useful code quickly.

Bugs Rust won't catch
In April 2026, Canonical disclosed 44 CVEs in uutils, the Rust reimplementation of GNU coreutils that ships by default since 25.10. Most of them came out of an external audit commissioned ahead of the 26.04 LTS. I read through the list and thought th…

Ghostty is leaving GitHub
Since then, I've opened GitHub every single day. Every day, multiple times per day, for over 18 years. Over half my life. A handful of exceptions in there (I'd love to see the data), but I can't imagine more than a week per year.

A good AGENTS.md is a model upgrade. A bad one is worse than no docs at all
We pulled dozens of AGENTS.md files from across our monorepo and measured their effect on code generation. The best ones gave our coding agent a quality jump…

WASM is not quite a stack machine
Everyone knows Wasm is a stack machine. Wikipedia says so, the official Wasm design specification says so, you get it. I thought so too. That is, until I started writing Wasm code – not compiling for Wasm, but writing the instructions by hand. And I found out that there exists a major difference between Wasm and all…
