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.

Lack of modern scientific libraries written in C
C++ offers tools for writing better APIs, and since the addition of concepts in C++20 it offers much better API enforcement. Writing an equivalent to libraries such as {fmt} or EVE is not possible in anything we’d call C.

Library that could generate vectorized code for different instruction sets?
Here is a doc on how we suggest to do it: https://jfalcou.github.io/eve/multiarch.html Here is complete code of that example: https://github.com/jfalcou/eve/tree/main/examples/multi-arch

SIMD intrinsics and the possibility of a standard library solution
My source for this was the statement:
-
C++'s smaller cleaner language
Indeed you cannot. Then again, you couldn't write a library like fmtlib in C in the first place. I mean why do you complain about C++ features which enable you to write libraries you otherwise couldn't? How would you expect to implement equivalent libraries to EVE or mp-units in C alone?

C++'s smaller cleaner language
For instance, maybe I'm just overestimating how verbose C++ would have been, or maybe I managed a particularly concise Rust AOC, but my solutions haven't been bad at all. See last year's, with no dependencies outside the standard library: https://github.com/rpjohnst/aoc2021/tree/main/src/bin
