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.
We haven't tracked posts mentioning Minizip-ng yet.
Tracking mentions began in Dec 2020.
Zstandard Worked Example
Thanks for the feedback! I've opened an issue to track this 
* Levels 1-19 are the "standard" compression levels.
* Levels 20-22 are the "ultra" levels which require --ultra to use on the CLI. They allocate a lot of memory and are very slow.
* Level 0 is the default compression level, which is 3.
* Levels < 0 are the "fast" compression levels. They achieve speed by turning off Huffman compression, and by "accelerating" compression by a factor. Level -1 has acceleration factor 1, -2 has acceleration factor 2, and so on. So the minimum supported negative compression level is -131072, since the maximum acceleration factor is our block size. But in practice, I wouldn't think a negative level lower than -10 or -20 would be all that useful.
The first 4 bytes are the magic number and the last 4 bytes are the checksum  which you could always just chop off if you wanted (it's legal to omit the checksum, see the spec). That would get the total overhead down to 5 bytes.

gzip certainly doesn't help. Switching to zstd should be an easy bit of low-hanging fruit, at least for save times.

Really wish this was part of official zstd (https://github.com/facebook/zstd/issues/395#issuecomment-535...) and not a contrib / separate tool.10 projects | news.ycombinator.com | 22 Apr 2022

What are some alternatives?
LZ4 - Extremely Fast Compression algorithm
Snappy - A fast compressor/decompressor
LZMA - (Unofficial) Git mirror of LZMA SDK releases
7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard
ZLib - A massively spiffy yet delicately unobtrusive compression library.
brotli - Brotli compression format
zfs - OpenZFS on Linux and FreeBSD
LZHAM - Lossless data compression codec with LZMA-like ratios but 1.5x-8x faster decompression speed, C/C++
LZFSE - LZFSE compression library and command line tool
zlib-ng - zlib replacement with optimizations for "next generation" systems.
rsync - An open source utility that provides fast incremental file transfer. It also has useful features for backup and restore operations among many other use cases.
