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.

Intel QuickAssist Technology Zstandard Plugin for Zstandard
It's obsolete. It's limited to 32KB LZ window with huffman coding. Zstd can use a much larger window (8MB recommended) and a much better entropy coder: https://github.com/Cyan4973/FiniteStateEntropy

Silly Lossy Text Compression Idea

https://arxiv.org/abs/1311.2540
> The modern data compression is mainly based on two approaches to entropy coding: Huffman (HC) and arithmetic/range coding (AC). The former is much faster, but approximates probabilities with powers of 2, usually leading to relatively low compression rates. The latter uses nearly exact probabilities - easily approaching theoretical compression rate limit (Shannon entropy), but at cost of much larger computational cost.
