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
Sounds similar to: https://github.com/Cyan4973/FiniteStateEntropy
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.

ELI5: How exactly does winrar profit without a major loss with their current business plan?
Their SDK is in the public domain though.

Searching Compressed Space
And that links to https://www.7-zip.org/sdk.html , in the download there see the DOC folder for documentation? I really can't figure out how that somehow 'sends you back to python's lzma'...
What are some alternatives?
Snappy - A fast compressor/decompressor
zstd - Zstandard - Fast real-time compression algorithm
LZ4 - Extremely Fast Compression algorithm
zlib-ng - zlib replacement with optimizations for "next generation" systems.
ZLib - A massively spiffy yet delicately unobtrusive compression library.
brotli - Brotli compression format
LZFSE - LZFSE compression library and command line tool
PhysicsFS - PhysFS++ is a C++ wrapper for the PhysicsFS library.
LZHAM - Lossless data compression codec with LZMA-like ratios but 1.5x-8x faster decompression speed, C/C++
