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?

Most of the time is spent parsing, but this problem lends itself nicely to a SIMD formulation, which using vectorclass doesn't even require detailed knowledge of the intrinsics. Hot runs take ~14 µs on a Core i9-12900K, including I/O. Full code is (here)[https://github.com/ahans/aoc2022/blob/main/cpp/day04.cc], the interesting part is this, where we process 32 elements at once:
- Significantly faster quicksort using SIMD
- Parsing JSON faster with Intel AVX-512
- What do you think is faster for batch-processing a lot of "double-type" arithmetic?
What are some alternatives?
