managarm VS WingOS

managarm is pretty clean from what I remember.

Somewhat related, Managarm[0] also attempts to be Linux compatible, but has a microkernel, multiserver design.

Neat idea. There is some research done on fully async OSes like https://github.com/managarm/managarm

If you haven't already, I'd hang out with the Managarm crew. Prety friendly, and what they're doing with C++ and async is very cool!

But well, maybe you should look at Managarm.

You can find more information on the project on our github page here. It is mostly a hobby project, so me and the other developers like to work on it in our free time.

Not hosted on rust-osdev but the Managarm project (an OS that focuses on async and that is primarily written in C++ so far) recently gained a rustc port and ports of some basic utilities written in Rust (ripgrep, exa). Support for Rust drivers is in the works (but still requires adding support for some libraries first that wrap the low-level system call interface).

If you have never seen an async OS, then you must’ve missed Managarm, a fully asynchronous operating system written in c++20. It’s a cool thing to check out, runs on x86_64 (a port to a raspberry pi4 is in progress) and has an extensive userland with various Linux applications running on a custom written libc. In case you’re curious, the repo can be found here: https://github.com/managarm/managarm

> I'm not sure why one would write a new OS in C++ in 2021/2022

numbers of hobby C++ OS started from scratch which went from zero to GUI in a couple years: at least 4 - SerenityOS, this, https://github.com/skiftOS/skift, https://github.com/Supercip971/WingOS

how many in other languages ?

Get him to join the OSDev discord chat. Most of the people there started learning programming in the middle of the pandemic and are now building complex projects. Group is mostly kids his age, 12-16 year olds, learning to hack around. Like this 13 year old or this 15 year old.

If you had put all those time into 1 long term project or two, like that highschool kid I linked above who nearly got a Google SWE internship, or like this 14 year old kid who started learning how to build an operating system last year in lockdown time and now has this to show for, you would've been miles ahead of the competition and interning at Google by your freshman year or have strong chance to get into FANG by the time you graduate. Instead you are here, thinking about what school to waste money on, scheming about a several year plan where you have a smaller chance get to one of these FANG companies. I said smaller chance because you can't just transfer from a top PH university to a US target school for CS unless you won a renowned international competition, your best chance then in your proposed path is either:
