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.

Does epub compress well?
You should look at Precomp - an apparently abandoned, but awesomely working arhiver that is dedicated to compressing those ZIP-based formats, and compresses them twice-thrice as small as LZMA2 can.
- Any suggestion for compressing a large batch of photos and videos into a single zip?
- Compression for Documents

Putting 5,998,794 books on IPFS
You can also have a look at this packer. It compresses PDF and EPUB 2-3 times smaller than 7z at maximum settings, at half the speed. I keep all my books in it and never had a problem.
- .bin compression

libgen currently adds around 1,300 books a day
There is an opensource archiver called precomp that is designed specifically for e-documents and compresses them 2-3 times smaller than 7z in ultra mode. It works, and I keep my e-books in it. However, it seems nobody else does, and development has stopped due to lack of interest.

AWS switch from gzip to zstd – about 30% reduction in compressed S3 storage
There are tools like preflate [1] or precomp [2] that guarantees a bitwise identical reconstruction, of course modulo bugs.

Which compression method for archiving OS ISOs?
You may use "precomp" in order to seek and uncompress those parts. Then you can use a better compression algorithm : http://schnaader.info/precomp.php
-
Is there any research as to what's the best way to compress each file type?
Precomp http://schnaader.info/precomp.php is a program which will seek compressed parts and decompress those parts in order to compress with another algorithm. This greatly improve compression ratio with the other algorithm.

How can I perfectly recreate a PNG losslessly compressed to JXL?
This may be of help. (a255854 and d649919)

Pigz: Parallel gzip for modern multi-processor, multi-core machines
That's really confusing since `pixz` exists and its "pixie" pronunciation actually works

Xz format considered inadequate for long-term archiving
pixz (https://github.com/vasi/pixz) is a nice parallel xz that additionally creates an index of tar files so you can decompress individual files. I wonder if dpkg could be extended to do something similar.
-
The best datahoarding hint that changed my live: use RAR archives (or any other archive format, really)
There's pixz, which indexes the tarball, allowing listing/extracting individual paths without decompressing the whole thing.
-
Hop: 25x faster than unzip and 10x faster than tar at reading individual files
Also relevant is pixz [1] which can do parallel LZMA/XZ decompression as well as tar file indexing.

7-Zip 21.0 alpha introduces native Linux support
Yes, it's as easy as installing pixz with symlinks pointing to xz (I think Debian even does this automatically as part of its post-installation scripts).

PeaZip 7.7.1 released!
Not quite what you're asking, but if you're a 7-Zip fan and on Linux, you might be interested in pixz.
