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.

Show HN: How to compile C/C++ for WASM, pure Clang, no libs, no framework
This was a topic at CppCon'19 (seems like exactly the same use case as you are describing: teaching!). Take a look at https://www.youtube.com/watch?v=5N4b-rU-OAA. I think it relies on the LLVM fork, so not sure how well it'll work for you, quick web search points to: https://github.com/binji/llvm-project.

Using Firecracker and Go to run short-lived, untrusted code execution jobs
Here are some more ports of LLVM and clang to the browser:
* https://github.com/kripken/llvm-js
* https://github.com/tbfleming/cib
* https://github.com/jprendes/emception
LLVM just does pure computation, really, so it's not hard to port to wasm - much simple than say Python (which has also been ported several times). The only challenges with LLVM are the build system (which has self-execution), working around some issues like clang wanting to open a subprocess, and adding some ifdefs.

Show HN: How to compile C/C++ for WASM, pure Clang, no libs, no framework
That is half of what I would need for a project, the other half being Clang itself running in the browser (to use for teaching), in theory there is [1] since many years, but in practice it never worked for me (even now I get "Runtime error: memory access out of bounds")

Do any Browser Based C Static Code Analysis Tools Exist?
It seems that there's a project doing exactly that: https://github.com/tbfleming/cib

Rust programming concepts for JavaScript developers
It takes some work (mostly due to LLVM building code to run later in its build system as it goes), but it's very feasible. LLVM has been ported to Wasm (and before that to JS) many times, for example:
https://github.com/jprendes/emception (2021)
https://github.com/tbfleming/cib (2017)
https://github.com/kripken/llvm.js (2012)
I agree it would be great to see this repl running 100% in the browser!
