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.

Oasis – a small, statically-linked Linux system
Michaelforney has also built croc [1], a qbe based C compiler. Really impressive!

Minias – A mini x86-64 assembler for fun and learning
A word of warning for those wondering: this is not for Intel syntax, despite referencing the Intel doc.
Minias can assemble itself
...but it's written in C and uses a parser generator? IMHO it feels a bit backwards --- and perhaps even a bit cheating if you're doing this for a "bootstrap pilgrimage" --- to write a lower-level tool in a higher-level language. On the other hand, the same author also links to a C compiler in C, without a parser generator: https://github.com/michaelforney/cproc

Faster Shell Startup with Shell Switching
David Korn's ksh93 was passed on to a new set of developers, who attempted to release a new version; AT&T rolled back these changes due to performance problems which raised questions of support status. It does appear that ksh93 development has resumed, and a new version was released late last year.
https://github.com/ksh93/ksh/releases
The independent pdksh spawned mksh, which is the default shell used in Android (as it has a BSD license); mksh appears to be very much active.
http://www.mirbsd.org/mksh.htm [https site has cert problems]
OpenBSD also forked oksh from pdksh. This is certainly well-maintained.

CVE-2022-45063: Xterm
I don't know if this is helpful or just annoying unsolicited "advice"
Anyway, for those of us who like openbsd ksh(all two of us) which is derived from pdksh. there is the project oksh.

OpenBSD 7.0 Released
...and that ksh descended from pdksh, and is distributed as the oksh portable project here:
https://github.com/ibara/oksh
The MirBSD Korn Shell also descended from pdksh, and it can be found here:
http://www.mirbsd.org/mksh.htm
I don't know about the feature differences and code quality between these two; they both implement most of ksh88, and a small amount of ksh93.
I prefer mksh when I need something more than a POSIX shell.
