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.

The Linux Kernel Prepares for Rust 1.77 Upgrade
This is a good guide on building small Rust binaries: https://github.com/johnthagen/min-sized-rust
This talks about going to extreme lengths on making the smallest Rust binary possible, 400 bytes when it was written, https://darkcoding.net/software/a-very-small-rust-binary-ind...
The thing is, you lose a lot of nice features when you do this, like panic unwinding, debug symbols, stdlib… for kernel and some embedded development it’s definitely important, but for most use cases, does it matter?

Making Rust binaries smaller by default
Are you sure? If so then this is awesome news, but I'm a bit confused; the commit in that min-sized-rust repo adding `build-std` to the README was merged in August 2021: https://github.com/johnthagen/min-sized-rust/pull/30
Are you saying that at that point the feature still hadn't "landed in Rust nightly" until recently? If so then what's the difference between a feature just being available in Rust nightly, vs having "landed"?
It's really a shame that Rust includes the stdlib piecemeal in binary form, debug symbols and all, in every resulting binary.
I do love Rust but binary sizes have always annoyed me greatly and I always had this nagging feeling that part of all programmers don't rake Rust seriously because of that. And I actually have witnessed, several times in the last 2-ish years, older-school programmers berate and ignore Rust on that basis alone (so the author is quite right to call this out as a factor).
Looking at the https://github.com/johnthagen/min-sized-rust repo, final binary size of 51 KB when compilation / linking / stripping takes stdlib into account (and not just blindly copy-pasting the 4MB binary blob) is acceptable and much more reasonable. I wouldn't care for further micro-optimizations e.g. going to 20KB or even 5KB (further down the README file).
I also don't use nightly in my Rust work so I guess I'll have to wait several more years. :(
My go to reference when I want to reduce rust binary size is the excellent https://github.com/johnthagen/min-sized-rust, a set of guidelines on how to reduce size with explanations of the consequences

Was Rust Worth It?
Rust binaries are by default nowhere close to 500MB. If they are not small enough for you, you can try https://github.com/johnthagen/min-sized-rust. By avoiding the formatting machinery and using `panic_immediate_abort` you can get about the size of C binaries.

Announcing lavagna v2, a collaborative blackboard made with bevy and WebRTC
And what about the binary size? Applying some cheats found in the Unofficial Bevy Cheat Book and in the Minimizing Rust Binary Size article I’ve achieved to fit the whole wasm binary in less than 10M, which become 2.8M when gzip compressed.
