This article brilliantly demonstrates the elegance of simplicity in systems design, proving that even complex concepts like operating systems can be demystified with clarity and minimalism. It's a reminder that understanding fundamentals often unlocks deeper innovation. How might this inspire rethinking other "big" systems?
A noble idea, but Github is literally littered with hobbyist home-grown Unix-like kernels in C. As an industry are we not supposed to be trying to move away from hoary old unsafe C? Could we not have a hobbyist educational OSes in more of the C replacements? Drew DeVault wrote Bunnix in Hare, in one month. There's the proof of concept. How about tiny toy Unix-likes in Zig, Nim, Crystal, Odin, D, Rust, Circle, Carbon,…
Most of them don't seem to understand how anything substantially different could exist in the world of computing - every other language and operating system is seen as either an inferior copy, or as another layer of abstraction building on top of C and UNIX.
Author here. I wrote this book so you can spend a boring weekend writing an operating system from scratch. You don’t have to write it in C - you can use your favorite programming language, like Rust or Zig. I intentionally made it not UNIX-like and kept only the essential parts. Thinking about how the OS differs from Linux or Windows can also be fun. Designing an OS is like creating your own world—you can make it how…

You can follow the MIT course and use QEMU if so wish.
Link to the MIT course?

this comment reads... a lot like chatgpt
Shameless plug: I've written hobby OS (well, a kernel actually) in Nim for x86-64[0] and it's all documented as well. I put its development on hold until I create a JetBrains plugin for Nim (in heavy development right now).
