This short story is not really about htop, or about the feature request that I’ll use as an illustration, but about what are the core principles that drive the development of a bit of software, down to every last detail. And by “core principles” I really mean it.

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…
