aero VS x86_64

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

Yes, while it may seem on the surface like the blog hasn't been updated in a while, the whole rust x86 project is under active development:

I see - looking at the source code of x86_64 library, I noticed that:https://github.com/rust-osdev/x86_64/blob/master/src/structures/idt.rs#L516What does that line do? I don't know Rust, but it feels like it repeats the first 32 IDT entries (which are for exceptions) for rest of the IDT.
