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 Curious Case of MD5
BLAKE3 is faster than hardware accelerated SHA-2 because the tree mode used in BLAKE3 allows hashing parts of a single message in parallel (with SHA-2, parts of a single message have to be hashed one after another, and parallelism is only used in workloads where you process multiple messages at the same time).

Can I concatenate multiple non-crypto hash functions to reduce collision?
SHA256 is high quality but typically a bit slower. Next Go version will have faster SHA256 on some amd64 CPUs - until then you can try sha256-simd which offers the same.

I need to find a custom hexadecimal string that when encrypted starts with a certain specific hexadecimal string(77656e6f7469 in our case). I tried randomly generating strings encrpyting them and checking them, realized it would take too much time. Any help?
I am not sure, if you can achieve a reasonable speed with Python though. You probably have to use a compiled language or run it on GPU. I found this very fast implemenation in Go which uses special CPU instructions (the AVX2 or SHA extensionsm depending on your CPU model) to speed up the calculation: https://github.com/minio/sha256-simd
