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.

C++ Show and Tell - December 2022
I made SpeciaLUT to convert bool/enum runtime tests to compile-time conditionals — by compiling all branching combinations in hot functions and saving them in a lookup-table, so the optimal one can be called at runtime. Reason: as an HPC consultant I encountered many codes that grew without good architecture, in which features would just be added and branching would propagate through all levels. This yields 10% to 50% performance increase in such codes.

Runtime-constant propagation and branching optimization strategy
I have implemented this as a C++ library, where you extract const states as template parameters, and the library compiles all specializations and allows you to choose the optimal one at runtime.

Runtime calling of a template specialisation using compile-time LUTs
So here's my C++20 implementation of the above: SpeciaLUT

A good alternative to Matlab's fminsearch?
This library has a minimizer which can be used with and without knowledge of the derivative. See chapter 3 in the description for a simple example.
