aero VS WingOS

This feels like an ad; the blog post and the README feel like they were written to sound complicated and smart rather than tell the whole truth. Like, "On boot, the kernel has full access to the memory and is allowed to write where it should not (its own code, for example)"? Apart from the fact that ring 0 will always have full control, the MMU also exists. Also, the "48k" (the kernel has 34324 lines of non-comment code, the rest are in the other repos I assume) LOC are obvious when you consider code like src/syscall/mod.rs:717 is present.

To be fair, this is impressive, but its a basic monolithic kernel written for a school project, with the "twist" that it is in Rust and uses Linux syscalls.

For anyone who is interesting in more Rust UNIX-like kernels, Aero (https://github.com/Andy-Python-Programmer/aero) is farther ahead supports running quite a lot of recompiled Linux userspace, including dwm and WebKit.

https://github.com/Andy-Python-Programmer/aero/blob/master/src/aero_kernel/src/mem/paging/addr.rs especially obvious, if you look at the first version of this file:

There is progress in implementing the DRM subsystem (cc https://github.com/Andy-Python-Programmer/aero/blob/master/src/aero_kernel/src/drivers/drm/mod.rs) but currently it only implements a small portion of the subsystem. But yea, this was one of the blocking points.

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.

you can compare with initial commit: https://github.com/Andy-Python-Programmer/aero/commit/3ee1c052454a1386dc8d1688b5ca9d616e3a907b

> 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 ?

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:
