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).
An Intel 8080 processor emulator written in less than 4K of C language and able to run CP/M. It won the Best of Show category (first place) of the 19th IOCCC. The 8080 originated the Zilog Z80 and started the personal computer's revolution.

This document has been assembled to supplement a set of instructions about writing one's own bootloader for the RP2040. Writing a bootloader requires some understanding of the boot sequence, but it became a bit too cumbersome to include that explanation in the bootloader documentation.

How much Vitamin D should I take? This is still the looming question, and it’s time to address it. First, though, imagine that someone in a public forum online asked me, “How much metoprolol (a…
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…
