Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[Media] I'm comparing writing a double-linked list in C++ vs with Rust. The Rust implementation looks substantially more complex. Is this a bad example? (URL in the caption)
it’s even written by the same person that wrote the Nomicon (the guide to the dark arts of unsafe)

Rust books to read
If you want to dive deeper you can always have other options but now there are concrete cases, if you want to do low level thing https://doc.rust-lang.org/nomicon/ while if you want multi thread/concurrency stuff https://marabos.nl/atomics/ . There are many many books so you will have to point yourself to what you want

Thread-shared boolean flag
Nonononono. SeqCst is the most error prone memory order: https://github.com/rust-lang/nomicon/issues/166

[Media] Hashmap behaviour inside a loop due to lifetime issue
Hope this helps. For more details, see the Rustonomicon. I referenced the subtyping chapter here extensively.

Unsafe Rust
Nice video! Glad I could help out. This stuff is hard, and I'm still learning a lot about it myself even years later. The Rustonomicon is a great read if you haven't already.

CppCon 2022 Best Practices Every C++ Programmer Needs to Follow – Oz Syed
That is not what UB means. Undefined Behaviour is behaviour that the compiler is allowed to assume will never happen, and which can consequently cause miscompilations due to optimisation passes gone wrong if it does in fact occur in the source code.
It's true that Rust does not have a written specification that clearly delineates what is and isn't UB in a single place. But:
1. UB is impossible in safe code (modulo bugs in unsafe code)
2. There are resources such as the Rustinomicon (https://doc.rust-lang.org/nomicon/) that provide a detailed guide on what is and isn't allowed in unsafe code.
In practice, it's much easier to avoid UB in Rust than it is in C++.

How to write deserializer for custom binary protocol?
However, this is a wide topic out of scope for a Reddit comment, so maybe just read the Rustonomicon. It explains everything about data handling in Rust.

Performance critical ML: How viable is Rust as an alternative to C++
The ownership model & borrow checker makes rust a bit of an awkward language in which to write complex data structures like trees and graphs. It can be done - since you can always use raw pointers & unsafe code when you absolutely need to to treat rust like C. But the language fights you, and the community can get a bit moralistic about this sort of thing. The rust nomicon is a fantastic resource for learning the limits of the borrow checker, and where and how to use unsafe code correctly. You will need unsafe less than you think you will, but sometimes you will have no choice.

RustPython – A Python-3 (CPython >= 3.11.0) Interpreter written in Rust
It does support calling into other compilers and toolchains through build scripts and such. Take cc-rs[0] for example: this allows building C and C++ files natively without even calling an executable yourself.
In practice, I'd expect libraries to just call make/cmake/ninja for you, or (like openssl-sys) ask you to install the necessary libraries using your favourite package manager.

Any crates for compiling C ( or other language ) from a rust binary?
The cc crate (https://github.com/rust-lang/cc-rs) is widely used for compiling C code from Rust (often in a build.rs file for the purpose of wrapping a C library so that it can be used from Rust). However, I believe it generally does expect a C compiler to be present.

Calling C code from Rust
It might be quite tedious to compile static library manually every time we make changes in C code. The better solution is to instead utilize the cc crate, which provides an idiomatic Rust interface to the compiler provided by the host.

Maintain It with Zig
> You're splitting hairs in a weird way. rustc cannot compile C code. zig can.
But why do I care? I don't use rustc directly, the build system of choice does. And very few of the major build systems have an issue handling multiple languages.
Cargo (rust's build system) supports build scripts and the community has already created C/C++ compiler hooks such as https://github.com/alexcrichton/cc-rs
rustup and cargo also provide easy cross-compilation support, too.

Windows can't find link exe
I think it's getting confused because link.exe is in your PATH. But it's not the link.exe it expects. Link tools are detected using the cc crate so it would need to be fixed there. Would you be willing to open an issue about this?

Most loved programming language Rust sparks privacy concerns
It’s not super well-documented, but there is an option to change this. --remap-path-prefix $(pwd)= in your RUSTFLAGS will usually do the trick. If you have any C dependencies you’ll also need similar things in CFLAGS, see https://github.com/alexcrichton/cc-rs/issues/593
