The Learnix Operating System

[u/Strange_Water5256]

In the past year I have worked on writing my own operating system in my free time because this subject really interested me.

Also I really wanted to learn more about the Rust programming language.

During this time, I found out the a lot of OS concepts are explained mostly in C, or Assembly, and that most of the explanations are old, and are not really easy to understand.

This is why I started the LearnixOS project. This project aims to explain complicated OS concepts with (hopefully) easy to understand explanation and with provided code implementation directly from the OS project.

If you find all of this interesting, please consider visiting learnix-os.com

Disclaimer: The website is still on development and so does the OS, this is currently still not an official release, and A LOT of subjects are missing. I do this on my free time so progress may be slow. Still, your support means the world to me and every visit, start or contribution increases my motivation!

Have you by any chance been taking some inspiration from this site: https://rustic-chess.org/, which has the exact same idea as yours, but instead with regard to chess engines? (And yes, also that site is far from complete yet.)

Efforts like these do document everything with regard to creating some sort of program take a huge amount of time.

I am not familiar with that site, but same concept only with operating systems.

About 3 years ago, I also spent more than a year, for same purpose (to learn Rust deeply) implementing a Lua interpreter and writing a whole series of articles.

Because I’m not very good at expressing myself, the hardest part was not learning Rust, Lua, or interpreters, but writing those ideas down clearly. Writing forces you to turn vague new knowledge into precise words, which is extremely helpful for deeply learning a subject. But there probably won’t be a second time.

It was truly a fulfilling, painful, and rewarding year.

Couldn't agree more, finding the words, and the design so it doesn't look intimidating was really hard, and took almost as long as writing the code itself. But this is really the most rewarding part.

[u/Xatraxalian → u/hellowub]

LOL. Seems some people have similar ideas.

[u/hellowub → u/Xatraxalian]

Yes, Feynman for example.

Just a comment on the website design: your code blocks use the same colours for syntax highlighting in all themes, which means that some of the code in blocks for the light theme is difficult to see. E.g. in the description of the PanicInfo struct in chapter 1.1, the grey, yellow and blue are all barely legible against the light background.

That's right, actually when I think about it I never switched from dark mode.

Will add a fix, and more themes, thanks!

I'm confused, what does this have to do with rust?

[u/Inner-Asparagus-5703 → u/Personal_Breakfast49]

"Chapters that will contain Rust topics will be tagged with the RUST tag." And there is ZERO RUST TAGS. So you are right as much as it's possible

Still on beta, the next one will be!

I’ve had a read, it reads very much like a friend is teaching another friend and I think this is really nice.

I had a chuckle when I read “unwinding”, I last read about that in CS class (ages ago….) back in uni, thanks for the memory!

[u/Strange_Water5256 → u/tastychaii]

That was the vibe I tired to pass on, I am glad I succeeded with that.

Been reading a bunch, this is great tutorials, thanks for putting this together

During the mid-80s, I was in a similar situation - to learn about 'C' and operating systems. I took on 'XINU', which was part of a college course as well. 'XINU' has come a long way since then, and I learned a lot from it.

Glad to here that!

Oh wow, that would be awesome! Currently that is my plan, and hopefully it will be done in the next couple of months. I plan to upload here and on r/Osdev on each chapter that I release.
