os-tutorial

I wish instead of discussing typos, folks her who surely know better (or author) could shed light on how this project compares to the many other existing projects, like https://github.com/cfenollosa/os-tutorial, https://littleosbook.github.io/, https://github.com/tuhdo/os01, https://github.com/prakhar1989/awesome-courses?tab=readme-ov... or even just "OPERATING SYSTEMS DESIGN AND IMPLEMENTATION" by Tanenbaum

While I agree this might be a fun resource and useful example code for various aspects of legacy x86 interfacing, I would urge anyone who hopes to actually get into OS development to ignore this (and in fact every other tutorial I’ve ever seen, including those hosted on the popular sites). For all the reasons stated in the link from the README [1] and agreed by the author, this project should not be followed if one wants to gain an understanding of the design and implementation of operating systems for modern systems. Following it will likely lead only to another abandoned “hello world plus shell” that runs only in emulation of decades old hardware. My advice is get the datasheets and programmers’ manuals (which are largely free) and use those to find ways to implement your own ideas. [1] https://github.com/cfenollosa/os-tutorial/issues/2

I mean... on the one hand, more people getting in the field may (or may not, I didn't measure) mean less people whose vocation is software. On the other hand, if that can cheer someone up... * https://ladybird.org/ * https://github.com/gorhill/uBlock * Zig rebuilt a C compiler from scratch https://ziggit.dev/t/zig-as-a-c-and-c-compiler/10963 * Rust rebuilt the core nix utilities from scratch https://github.com/uutils/coreutils I've heard a bunch of people making their own OS from scratch just to see how it works, heck there are guides online (https://github.com/cfenollosa/os-tutorial ... 30k stars...) So... Cheer up ! If people are building all that, I'm sure innovation and creativity are at least not dead everywhere.

Totally unrelated. But this guy has an amazing OS-from-scratch tutorial [0]. [0] https://github.com/cfenollosa/os-tutorial

Correct. Try these two: https://github.com/DoctorWkt/acwj https://github.com/cfenollosa/os-tutorial

Let me plug in my own tutorial :) https://github.com/cfenollosa/os-tutorial

This is so exciting! I never got to write my own boot sector in college, our lab exercises were kind of advanced and we had a lot of starting code. That document inspired me to create a Github repo with only the code, split into micro lessons. Feel free to check it out, I'll update it at the same pace that I process the document and learn stuff myself https://github.com/cfenollosa/os-tutorial
