You will now see the directory listing. This website was actually created for my primary side project: a simplified programming language for beginners. I just added a blog folder there for other things as well.

Branchful only wins via ILP when data becomes good predictable. But since Quicksort partitioning aims for a 50/50 split, it operates in the worst possible zone for a branch predictor. That's why branchless wins here, as proven by the benchmarks.

Author here. No, it's also called from the non_trivially_copyable branch (as a fallback). I'll fix that.

This post about strange attractors isn't as cool as this recent one: https://news.ycombinator.com/item?id=45777810. My visualization runs with my programming language, which is interpreted by WASM code and uses JS and Canvas – without WebGL.

This programming language, along with its IDE and tutorials, has been around for some time, but the TAB completion, which is helpful especially for beginners, is new.

Show HN: Tab completion for my small browser-based programming language Easylang

chrka — Fri, 03 Oct 2025 15:33:11 +0000

Hi HN! Tab completion makes it much faster to type variable names (correctly) and also helps you finding possible built-in commands.

The information about which inputs are possible is available, because the code is parsed up to the current position when the tab key is pressed.

Easylang is a small programming language designed for teaching and learning, but not only for that. It is also open source.

Have fun with it! C
