scamp-cpu VS aoc

Re the text editor, when I was writing an editor for my homemade CPU I used the one from this tutorial: https://viewsourcecode.org/snaptoken/kilo/index.html - it is 1000 lines of C.

I have diverged a bit from the tutorial because I didn't want syntax highlighting and I really wanted vi-style keybindings. Mine is at https://github.com/jes/scamp-cpu/blob/master/sys/kilo.sl (in my made-up programming language).

I made the computer myself: https://github.com/jes/scamp-cpu/

In case you're interested, there's more about this project in the github repo: https://github.com/jes/scamp-cpu/ and on my blog: https://incoherency.co.uk/blog/tags/cpu.html

This is really cool and unique. I poked around a bit, and the kernel is vaguely POSIX like, but written in a homegrown language with a compiler written in Perl[1].

Actually, I just found this! That's pretty much what I was looking for. That's what I would have linked if it had been me posting. :) This looks like a really interesting computer project!

Personally I just stick to raw arrays for most days, usually with static storage (so pre-allocated). Keeps things simple! Here's my repo.

Here's my solution. Sorry, I did go a bit overboard making it compact.

That was one heck of a tough day but also very satisfying. I spent quite some time working out a 3D rectangle splitting/merging algorithm on paper and then I had to go and implement that in C. It turned out pretty clean and idiomatic, if I may say so!

This was my first attempt (or at least in a very long time) at generating video. Here I'm generating raw RGB frames in memory and writing them to ffmpeg, which works well enough but it's a little primitive.

At 50 year sold and very stable, C must be one of the easiest languages to get working on old machines. Required just some of the polyfills I wrote back in 2020.

My original solution checked every character against every other character, which performed perfectly fine even for 14 chars, but it felt wrong.

First a straightforward solution with a double buffer, later realised you could do it in-place by just holding onto one value per row/column.

First wrote a short AWK program to convert the input to C and play with it while running a hopeless brute force attempt.
