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.

Monoio – A thread-per-core Rust async runtime with io_uring
Oh, I have written my own share of userspace C context switching libraries, I know all the gory the details :). For example see my minimalist [1] stackful coroutine library: the full context switching logic is three inline asm instructions (99% of the complexity in that code is to transparently support throwing exceptions across coroutine boundaries with no overhead in the happy path).
You need compiler help for the custom calling convention support and possibly to optimize away the context switching overhead for stackful coroutines, which is something that compilers can already do for stackless coroutines.
The duff device is just a way to simulate stackless coroutines (i.e. async/await or whateverer) in plain C, in a way that the compiler can still optimize quite well.

Declarative, non-intrusive, compile-time C++ reflection for audio plug-ins
Using gcc extended asm you can pass literal constants to the asm and they will be expanded textually (or at least their address will). I don't think the details are fully documented anywhere and I had to use intel syntax to make it work, but it might be possible even wit AT&T syntax.
Take a look a this[1] for example. See how trampoline, the destructor and the size are passed in with the 'i' constraint and are referred to their value with the %cX constraint (yes, the code is write only and even with a lot of comments I have only the most vague idea of what I was trying to do here).
Probably more work is require for PIC though.

Declarative, non-intrusive, compile-time C++ reflection for audio plug-ins
If you wrote a software that worked with soundflower it means that at some point you used to call either the CoreAudio API directly or any abstraction on top of it (RtAudio, PortAudio, ...). Thus harder to port to another OS :-)
Here the idea is to write the algorithms in a way that is more future-proof, by not having them to depend on any run-time API, just a generic specification. This way the algorithms will still be useful in 10 years when everyone has moved to API N+1, unlike a metric ton of existing audio software which depends on a specific audio / media-object API for no good reason (today ! When they were written C++ wasn't advanced enough to allow this at all)
