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.

Manipulating the Internal World Model of a Chess Playing Language Model
The Stockfish program can be set to play at strength level 0-20. Estimates of the levels' Elo is provided here: https://github.com/official-stockfish/Stockfish/commit/a08b8...
-
A chess terminal user interface implementation
- and handicapped Stockfish (https://stockfishchess.org).
The whole thing is at https://github.com/magv/bchess, and can be installed with just 'pip install bchess'.
- What could I contribute to chess as a developer?
-
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.

The Montreal Problem: Why Programming Languages Need a Style Czar
Some people's brains just work this way. Here's an example of a somewhat popular and regularly maintained library written in a similar style: https://github.com/enkimute/ganja.js/blob/6e97cb45d780cd7c66...
Once your learn to recognise the commonalities, you'll see examples everywhere. The most extreme and stereotypical version is the billboards written by some homeless people. You can probably picture it already in your mind's eye: A wall of very dense text with little whitespace or structure, and a mix of fonts and colours seemingly at random.
I had a brilliant mathematician friend who wrote like this. He would squeeze and entire semester's worth of study notes into a single sheet of paper, on one side. It was impenetrable gibberish to everyone else, but the colours and 2D positioning let him build a mental mind-map.
For people like this, if you reformat their code even a tiny bit, their mental map is invalidated, and they lose track of it completely and become upset. I discovered this (the hard way) when applying automatic code formatting tools to the codebases I mentioned previously.
Personally, I find this type of thing to be absolutely fascinating, because it's the intersection of many fields of study, and hence is under-studied. There's elements of pedagogy, psychology, literacy, compute science, etc...
It's an open question how we can get large groups of neurodiverse humans to collaborate on a codebase when they don't even "read" or "think" in compatible ways!

[Media] I finished my first rust project: a path tracer
I was watching bivector videos and how it could be a viable replacement for matrix algebra in video games and I have been very impressed by the intuitiveness and consistency of the equations. There is this ganja.js for demonstrating the graphics and has a rust generated code https://github.com/enkimute/ganja.js/tree/master/codegen/rust I'm too naive to understand the implementation, but I'm glad a library like ultraviolet is here to start paving the use of Geometric Algebra in computer graphics.

Manim: An animation engine for explanatory math videos
Well I've been on a real Geometric Algebra (aka Clifford Algebra) kick lately, and ran across ganja.js [1]. It's a single no deps file that is...impressive. 120k uncompressed, and with it you can construct any degree algebra (including the more esoteric hyperbolic/parabolic ones), render to canvas, svg or webgl(!). It also includes a clever little DSL parser and interpreter (it overloads the scientific notation to name basis vectors!) that lets you construct more complex things from simple things using various kinds of products.
The author, Steven De Keninck, is quite impressive as well, having got his start in the demoscene some time ago. He has a good video from 2019 that explains why this algebra is better than [matrices, tensors, vectors, complex numbers]. Of particular interest (to me anyway) is the 2D projective geometry.
I don't want to oversell it, but ganja is fucking amazing and there is a great deal I want to do with it. For one, I'd like to recapitulate my physics degree with it.
