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.

SQLite Helps You Do Acid
Indeed!
I was so glad to see you cite not only the Rebello paper but also Protocol-Aware Recovery for Consensus-Based Storage. When I read your first comment, I was about to reply to mention PAR, and then saw you had saved me the trouble!
UW-Madison are truly the vanguard where consensus hits the disk.
We implemented Protocol-Aware Recovery for TigerBeetle [1], and I did a talk recently at the Recurse Center diving into PAR, talking about the intersection of global consensus protocol and local storage engine. It's called Let's Remix Distributed Database Design! [2] and owes the big ideas to UW-Madison.

20 years of payment processing problems
> It sounds like payments might be part of the larger concept of declarative programming (DP)
Yes, exactly! The idea with TigerBeetle's state machine [1] is to expose double-entry accounting as higher level financial primitives, so that developers can think in terms of declaring transfers from one account to another. The business logic behind the scenes is detailed, but the interfaces and data structures are simple.
[1] https://github.com/coilhq/tigerbeetle/blob/main/src/state_ma...
> Maybe TigerBeetle could be generalized to support any multi-step distributed process?
That's part of the plan, that the distributed database framework of TigerBeetle can be used as a ”distributed Iron Man suit” to support any kind of state machine.

Distributed Systems Shibboleths
Surprisingly, some of the most powerful distributed systems algorithms or tools are actually deterministic. They're powerful because they can "load the dice" and so make the distributed system more intuitive for humans to reason about, more resilient to real world network faults, and do all this with more performance.
For example, Barbara Liskov and James Cowling's deterministic view change [1], which isn't plagued by the latency issues of RAFT's randomized dueling leader problem. Viewstamped Replication Revisited's deterministic view change can react to a failed primary much quicker than RAFT (heartbeat timeouts don't require randomized "padding" as they do in RAFT), commence the leader election, and also ensure that the leader election succeeds without a split vote.
Determinism makes all that possible.
Deterministic testing [2][3] is also your best friend when it comes to testing distributed systems.
[1] I did a talk on VSR, including the benefits of the view change — https://www.youtube.com/watch?v=Wii1LX_ltIs

Lies we tell ourselves to keep using Golang
This is the chasm problem, where people don't use a technology because people aren't using that technology, thus the technology has difficulty gaining adoption. I did see that Zig does have it's own killer app and startup that's using Zig: TigerBeattle.

Ask HN: Codebases with great, easy to read code?
Control flow statements should always be on their own lines, then it's easy to find all of them by visually scanning top-down, without needing to look all the way down each line.

Database functions to wrap logic and SQL queries
> In hindsight, data logic should be in the database itself.
This is the reason we are creating TigerBeetle [1] at Coil, as an open source distributed financial accounting database, with the double entry logic and financial invariants enforced through financial primitives within the database itself.
This is all the more critical for financial data, because raw data consistency is not enough for financial transactions, you also need financial consistency, not to mention immutability.
The performance of doing it this way is also easier. For example, around a million financial transactions per second on commodity hardware, with p100 latency around 10-20ms.

Building Payment systems for the World at Hackathons
You probably already know this — because we’ve mentioned it a few times — but Coil champions and supports open-source projects and is privacy-first, by default. Over the years, Developer Relations at Coil has championed and sponsored teams that write Open Web Documentations and projects that empower open-source developers to get paid. Coil has also incubated many open-source projects like Tigerbeetle and Rafiki.
