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.

Zstd Content-Encoding planned to ship with Chrome 123
I'm still unconvinced about this addition. And I don't even dislike Zstandard.
The main motivation seems to be that while Zstandard is worse than Brotli at the highest level, it's substantially faster than Brotli when data has to be compressed on the fly with a limited computation budget. That might be true, but I'm yet to see any concrete or even anecdotal evidence even in the issue tracker [1] while there exist some benchmarks where both Zstandard and Brotli are fast enough for the web usage even at lower levels [2].
According to their FAQ [3] Meta and Akamai have successfully used Zstandard in their internal network, but my gut feeling is that they never actually tried to optimize Brotli instead. In fact, Meta employs the main author of Zstandard so it would have been easier to tune Zstandard instead of Brotli. While Brotli has some fundamental difference from Zstandard (in particular Brotli doesn't use arithmetic-equivalent coding), no one has concretely demonstrated that difference would prevent Brotli from being fast enough for dynamic contents in my opinion.

Data Compression Drives the Internet. Here’s How It Works
- igzip 1,2 is best for very fast networks > 10MB/s
brotli bring little value at decompression for users

Pigz: Parallel gzip for modern multi-processor, multi-core machines
You can grab the version from the solaris userland repo I linked and use it without me completing a homework assignment. Just grab the pigz-2.3.4 source then apply the patches from [1] in the proper order. Maybe some of them aren't needed for non-Solaris.
1. https://github.com/oracle/solaris-userland/tree/master/compo...
I thought I had opened a PR for that a long while ago, but it doesn't show up on github these days. In any case, I did ask Mark Adler to review it. It was never a priority, then the code changed in ways that I don't really want to deal with.
While looking through the PRs, I noticed a PR for Blocked GZip Format (BGZF) [2]. That's very interesting, and perhaps suggests that bgzip is a tool you would be interested in.

- ZSTD 1.5.5 is released with a corruption fix found at Google

Pigz: A parallel implementation of gzip for multi-core machines
The bit I found most interesting was actually:
https://github.com/madler/pigz/blob/master/try.h
https://github.com/madler/pigz/blob/master/try.c
which implements try/catch for C99.
