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.

How do you generally go about finding the Jacobian of a complicated observation function for a Kalman filter?
To add to software for #1, look for packages that do forward-mode AD. For Jacobians (many outputs), forward-mode AD is often faster than back-propagation (reverse mode). I use ForwardDiff.jl which usually accepts any function the user might bass in as observation function https://github.com/baggepinnen/LowLevelParticleFilters.jl/blob/master/src/ekf.jl#L45 Here's a nice intro to forward and reverse mode ad https://github.com/MikeInnes/diff-zoo/blob/notebooks/backandforth.ipynb It's the second notebook in a series, might want to read the first as well if you find this topic interesting.

Ask HN: What are some examples of elegant software?
This is an obscure one, but Mike Innes "[automatic] differentiation for hackers" tutorial. It's a code tutorial, not software, if that counts. Both the way it's constructed and the functionality of Julia that gets shown off here.

posttest-cli beta testers wanted
This was the result searching for all the 35 stockfish benchmark positions to depth 6.

How many positions can the top GMs analyze per second? In engine terms what is the highest nps for humans?
Stockfish doesn't have a classical evaluation anymore. And before this, most of the time (around 90%), NNUE was used to evaluate.

Stockfish 16 Released +47 Elo gain over Stockfish 15 (Single threaded, UHO)
If you use ChessBase on a MacBook through Parallels, there's an issue where people have posted Apple Silicon compiles for Windows: https://github.com/official-stockfish/Stockfish/issues/4241

Stockfish 16 is ready!
Progress can be found here https://github.com/official-stockfish/Stockfish/wiki/Regression-Tests At 1 thread it has gained +18.3 elo on a balanced book, and +47.03 on UHO (unbalanced) book as well as +39.4 elo for FRC and +65.56 for DFRC. At 8 threads it has gained +14.33 elo on a balanced book and +49.46 on UHO (unbalanced book). Also testing was done on 8 threads with 180+1.8 (this is considered very long time control for fishtest standards) and progress was +9.45 on balanced book and +49.65 on UHO.
