The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

This is a legitimate line used for Stockfish development testing
Yeah, I noticed most tests still use older UHO lines (not sure why?) even though UHO 2022 came out a few months ago and has already been included in official stockfish development books list.

Stockfish 15 is now available
You mean this? These are not opening books, though they're called "books". They're PGNs with starting positions, usually a couple of moves into the game, that are used for statistical tests as having engines play from the regular starting position does not sweep the space of realistic game positions very well.

Are Tablebases Obsolete?
As you can see, the value of tablebases did decline significantly following the switch to NNUE evaluation. In fact it is just within the margin of error so we can't even conclude that tablebases increase the strength of Stockfish 14.1 at all. So then I decided to try using endgame positions to start. I used the endgames.pgn file from this Stockfish book repository, which is a huge set of imbalanced endgame starting positions. The results of these 20,000 game matches were:

If you let the strongest chess engine play itself with as much time as it needs to decide on a move, what sort of opening ideas does it go for? What does the game end up looking like?
In engine vs engine tournaments , we use books to increase the variety. Here you can download them https://github.com/official-stockfish/books.
- Today, we have the pleasure to announce Stockfish 14.1

Interested in creating, playing and testing your own chess engine?
you can have a look at openbench maybe, https://github.com/AndyGrant/OpenBench . It is currently a testing framework for chess engines (only invited ones) or fishtest. https://tests.stockfishchess.org/tests Stockfish testing framework. Both of these test if change A beats the master version using statistics. Both look at the git repository and download it and create/compile the engine, that might be another solution for you.

~20TBs on Striped Hard Drives / RAID0: What kind of hardware to support this setup?
FishTest has thousands of computers running 24/7 https://tests.stockfishchess.org/tests. Nerds at gcp,aws,universities burn thousands of GPU hours on lc0-client just to watch their GPUs warm up. They aren't just attaching 20tb of endgames to an old macbook.

Does (human + computer) combo beat computer?
if removing any rng from stockfish would gain elo it would be merged. If you think it gains elo feel free to submit a test to https://tests.stockfishchess.org/tests , but it doesn't so what your saying makes no sense.

What are some chess960 positions that are winning for white
Where did you get these numbers from? https://github.com/glinscott/fishtest/wiki/Regression-Tests shows an elo difference of 351.3 elo points. This is further exaggerated by the fact that sf9 lacks nnue and is particularly weak at the starting position and consequently 960 starting positions.

What makes SF15 better than 14? I mean, what do they do/program to improve performance?
You can see the various code changes in https://github.com/glinscott/fishtest/wiki/Regression-Tests . Both the actual change and the elo change from the code change.
