Hey HN! This is a fun/educational project I built to learn OS programming. I started working on it right after graduating high school last year and have been working on it on and off during my first year of university. It features a TCP/IP stack, an HTTP server, a RAM file system, a BIOS bootloader, paging and memory management, and concurrent tasks based on cooperative scheduling, along with a custom library. It's written in a C programming style focused on safety (based on a custom library of core abstractions) that's inspired by the writing of Chris Wellons (nullprogram.com).

There is a link to a test deployment in the README. The TCP/IP implementation is nowhere near perfect, of course, so there may be issues loading the page. I'm curious how the system holds up if this post gets any attention ;-)
