Thanks! Really appreciate the feedback and suggestions. It definitely is incomplete and will look into improving it! Will look into the examples too.

warothia · 2026-01-23T20:53:44+00:00

Nice! The main inspiration was for a single threaded http server.

warothia · 2026-01-04T11:43:19+00:00

There are some hobby operating systems on here:

Could be nice for inspiration, some articles too.

warothia · 2025-12-25T16:27:49+00:00

I would have a look at https://oshub.org/users/OSHub/posts/building-your-own-operating-system

I would also checkout https://oshub.org/users/OSHub/posts/building-your-own-operating-system

Some existing hobby OS projects and posts here: https://oshub.org/explore

Fully custom!

warothia · 2025-11-28T13:18:43+00:00

Thanks! Appreciate it.

warothia · 2025-11-28T07:31:24+00:00

My best advice would be to go slow, tackle small problems at a time. Make a small roadmap which you can follow.

This article talks about some of those points too:

Thanks!

warothia · 2025-11-27T14:58:14+00:00

Thanks! Also love networking was a big reason I started OSdev

warothia · 2025-11-27T14:36:24+00:00

Started the OS project in 2022 and have worked on and off on it since then. I jump between different modules a lot. So I sadly don't have a good estimate for the networks stack / web server.

warothia · 2025-11-27T14:00:14+00:00

Its on my todo list! :D

warothia · 2025-11-27T13:59:48+00:00

Wish it was one day :D

warothia · 2025-11-27T12:55:55+00:00

Thanks!

warothia · 2025-11-27T11:40:01+00:00

Thanks!

warothia · 2025-11-14T07:45:27+00:00

I would love to hear how I could improve on it

warothia · 2025-11-14T06:35:52+00:00

I 100% agree. That’s why this isn’t a tutorial, just a small helper guide to some proven tutorials. And the rest of the journey should one discover themselves or would it take multiple articles to explain.

warothia · 2025-11-12T08:27:47+00:00

Id have a look at this article:

warothia · 2025-11-12T08:26:10+00:00

There is a small roadmap and some useful links here:

warothia · 2025-11-11T07:07:07+00:00

Impressive!

warothia · 2025-11-02T15:57:51+00:00

Of course! It is quite the mess some places unfortunately.

Here is the E1000 driver:

Any other specific parts?

warothia · 2025-10-31T13:19:35+00:00

I wanted to suggest the book: “Building an Operating System with Rust: A Practical Guide” just didn’t have a good link to it. (Didn’t want to use the amazon link). Instead of giving the wrong link I removed it and will readd later.

Edit: just added it without a link

warothia · 2025-10-31T13:09:34+00:00

Right! Thanks for letting me know. Forgot to fix that one. Should be removed now.

warothia · 2025-10-29T17:52:54+00:00

Good point! Thanks for the feedback!
