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.

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.

Rule
My favourite is still that printf is Turing Complete

Trying out Reflection TS experimental
I guess I'm confused which compiler to use. Is this by lock3 the "demo" implementation which is superseded by clang 15.0-reflection (godbolt says that's the compiler used). I'm using clang for now
-
Experimental Clang implementation of TS Reflection is now available.
Is it related to the "meta" branch or a completely independent work ? (https://github.com/lock3/meta/wiki)

Adding reflection to an existing codebase
then there's no pure C++ solution, you either have to use alternative compilers such as https://github.com/lock3/meta/wiki or Circle, or use an external reflection system such as Qt's moc

Discussion on possibility of a compile-time printf
yup, that would be the "CPPX" compiler developed for prototyping reflection and metaprogramming features, also available here
What are some alternatives?
tinyformat - Minimal, type safe printf replacement library for C++
shaders - Circle C++ shaders
C++ Format - A modern formatting library
circle - The compiler is available for download. Get it!
