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.

Compilers for the Future
ELVM lacks a lot of features, but serve the purpose of simplifying the creation of new frontends.

Show HN: Lambda-8cc – An x86 C compiler written in untyped lambda calculus
How does it work? Is it translating the C source code of the 8cc C compiler to lambda calculus?
So like C -> ELVM IR -> lambda calculus?
https://github.com/shinh/elvm
If so, it seems like 8cc is doing most of the heavy lifting

awkcc: awk-to-C transcompiler (1988, 2011)
Interested parties should also check out awka (https://github.com/noyesno/awka) and ELVM (which can compile C into awk or sed, among various other things) (https://github.com/shinh/elvm)

Lisp in an “impossible” language, the most complex malbolge program to date
A C compiler that can output Malbolge (among many other esolangs) can be found at https://github.com/shinh/elvm - dunno if it has any relation to this work.
Note that the Malbolge (or rather LMAO/HeLL) backend was added back in July 2019, so I'm not so sure about their claim that "It's as of 2020 and 2021, the most advanced, usable Malbolge program ever created."

Few lesser known tricks, quirks and features of C
Somewhat related to this, printf alone in a loop is Turing-complete, by using %-directives like that. It was introduced in “Control-Flow Bending: On the Effectiveness of Control-Flow Integrity” (Carlini, et al. 2015) and the authors have implemented Brainfuck and an obfuscated tic-tac-toe with it.

well this is a brainfuck interpreter inside printf. I’m pretty sure there are plenty of c-to-bf transpilers.
