aero VS crates.io

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

Rust has a rich ecosystem of frameworks and libraries that let you read, parse, and manipulate text files, interact with cloud services and databases, and perform any other job that your project's development workflow may require. And because of its strong typing and tight memory management, you are much less likely to write programs that behave unexpectedly in production.

All the code discussed in this article can be accessed through this repository. For integration with existing projects consider using keyword_extraction crate available on crates.io.

So, be sure to double-check your critical libraries and be sure their alternatives exist in the Rust ecosystem. There’s a good chance the crates you need are available in Rust's crates.io repository.

The previous section was very simple, this section is also very simple but introduces us to cargo which is Rust's package manager, as a JS dev my mind goes straight to NPM.

Now, there has to be a place where all these packages come from. Similar to npmjs registry, where all node packages are registered, stored and retrieved, Rust also has something called crates.io where many helpful packages and dependencies are registered.

Before proceeding, let's check https://crates.io/, the official Rust package registry.

The most thrilling aspect has been the joy of writing the backend. It's like every struct, enum, and method in Rust forms this interconnected Multiverse of code , which you can see in crates.io which is best Documentation experience I Ever Had.

5. Crates.io

When using crates from eg. crates.io, and also things like std and core

Vendoring your packages was very tedious to even remotely get to work with Cargo. I spent a very long time getting Cargo to work together with cargo-local-registry. We vendor crates from crates.io and a custom internal registry.
