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.

games-emulation/dolphin-9999 is failing to build because devs switched to minizip-ng and zlib uses minizip. I'm not sure how to get it to build now, details in post.
(2) There are many packages that rely upon zlib and minizip and switching those underlying dependencies is easier said than done. We can't drop zlib completely and switch: "The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a lower threshold for code change." - https://github.com/zlib-ng/zlib-ng

Re: Zlib memory corruption on deflate (i.e. compress)
There are already active zlib forks (e.g. https://github.com/zlib-ng/zlib-ng), the problem is with having people move to them. It takes a lot of effort to move mindshare from the original version to a fork, there's some historical examples of it happening, but not a ton.

Using TAR files in ESP32 with SD applications for easy multiple file transfers
I am engineering a watch to play home videos of my children on my wrist - my Reflections project. I need an easy way to move multiple files from a Cloud based service to the watch. tar) and GZip are widely used standards to build and compress an archive of binary (for example, movies and sound files) and text (for example, JSON encoded procedural scripting command) files. Using tar I simplify my code to move one tar file instead of multiple individual files. The ESP32-targz library combines uzlib and TinyUntar to decompress and inflate tar files and works well with Arduino IDE 1.8.13, ESP32, and an SD card. This is my developer’s journal of the problems that I encountered and the work-arounds I used.
