mu
Soul of a tiny new machine. More thorough tests → More comprehensible and rewrite-friendly software → More resilient society. (by akkartik)
Project mention: Show HN: GDSL – 800 line kernel: Lisp subset in 500, C subset in 1300 | news.ycombinator.com | 2026-03-15Looks interesting. The next step may be to show some little fun examples built with it.
Here's my similar project from a few years ago, in case you want to compare notes:

Project mention: Show HN: I wrote a Christmas-themed Space Invaders clone in 8086 Assembly | news.ycombinator.com | 2025-12-24
I've had a goal for the past three years to learn Assembly language. This December, I finally put some real effort into learning the language. I followed the tutorials in Oscar Toledo G's "Programming Boot Sector Games" and used Gemini as a tutor to help explain the concepts I was stuck on. It was tempting at points to vibe code some of the trickiest pieces, but I found resisting the temptation and using Gemini just to be an expert tutor to answer my ignorant questions brought back the joy of coding again. The result is a Christmas-themed Space Invaders clone written in 8086 Assembly.
The code isn't perfect, and neither are my line-by-line comments, but it's a good exercise if anyone else is trying to learn a language.
The game compiles to a .com file and runs in DOSBox. I'm not trying to fit it into a boot sector (512 bytes) like the original tutorial (https://github.com/nanochess/Invaders/blob/master/invaders.a...), so my code assembles to more verbose (around 700 bytes).
