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.

Is there any hashing library for c++ Or any other way I can use SHA256 hash
For non-cryptographic purposes you can consider MurmurHash: https://github.com/aappleby/smhasher/tree/master/src
-
GateBoy – a gate-level Game Boy simulator
This is very impressive!
The creator—Austin Appleby—also created MurmurHash, which is very useful for data structures like Bloom filters. The canonical MurmurHash implementation was released with a handy non-cryptographic hashing test suite.

Thanks for your work, Austin!

Reasons to Prefer Blake3 over Sha256
> might be easier with a public domain license instead of the current ones
There reference implementation is public domain (CC0) or at your choice Apache 2.0

Google abandons work to move Assistant smart speakers to Fuchsia
Fyi, blake3 was released in 2019 and should probably be used over blake2 unless you have some strong reason not to. It's basically a reimplementation of blake2 with performance tweaks.

Six times faster than C
Many people will argue that today's compilers are so smart/optimized that you'd be a fool to try to outsmart the compiler with asm. I'm not 1 of them, but I know some. IMO it's all a bunch of bullshit, there's a goddamn reason all the cryptocurrency mining CPU/GPU code is all hand-written asm. there's a reason blake3 is written in asm ( https://github.com/BLAKE3-team/BLAKE3/blob/master/c/blake3_sse41_x86-64_windows_msvc.asm ) - but the thing is, 99.99% of the time, life is too short to outsmart the compiler (unless you're Alexander Yee)

[QUESTION] Low speeds when creating blake3 checksum?
I have been trying to optimize my code to create a fast hashing function to create and check b3 file integrity but b3sum is way way faster than my aproach, i have been trying to modify my code acordingly to https://github.com/BLAKE3-team/BLAKE3/blob/master/b3sum/src/main.rs with no luck, so if anyone can give me some tips/clues on how to achieve better speeds it would be incredible. Thx!!

A good hash function for DEFLATE?
BLAKE3 might be faster than KangarooTwelve and is also an XOF. It doesn't have the benefit of getting a working RFC draft proposal however.
-
PoxHash, a bespoke denovo hashing algorithm implemented dep-free in Rust and 5 other languages. Rust compiled with rustc with -O is faster than GCC-compiled C with -O3!
You're saying the hash speed is 133 kB/s? That's extremely slow, for example BLAKE3 achieves 6.8 GB/s which is over 50000 times faster. Nobody wants to use such a slow hash function.
