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.

Ask HN: Why are there no traditional language compilers that target the JVM?
There is the GraalVM Python Runtime, Renjin GCC-Bridge (for C, C++, R)...
I feel like all of this kind of exists but it's quite esoteric "non-standard stuff" and not necessarily something sane people want in production.

OpenJDK Proposes Project Galahad to Merge GraalVM Native Compilation
It'll help build cross-platform desktop applications. In theory, it'll mean hooking the build process up to a GitHub action to build platform-specific binaries, such as my FOSS KeenWrite Markdown editor[0], without having to have a copy of every operating system.
To my knowledge, cross-compiling "native" Linux and Windows binaries using Java requires duct tape, chewing gum, and warp-packer.[1]
GraalVM isn't a panacea, though.[2] For example, GraalVM cannot compile Renjin, a pure Java R interpreter, so you have to switch from Renjin to FastR. Switching isn't trivial.

How this sub treats Java ...
I just wanted to mention that C compilers exist for the JVM.
- Why it is that C++ can be compiled to JavaScript bytecode that is WebAssembly (using Emscripten), but it cannot be compiled to Java bytecode?

Avoid blundering: 80% of a winning strategy
> the player who committed more blunders lost 86% of the time
In some sense this is almost tautological. While finding an exact definition for a chess blunder isn't straightforward, here is one example from the Lichess UI:
https://github.com/lichess-org/lila/blob/b527746b179cdde6438...
Basically, if you make a move which decreases your winning probability more than 14% over the best move, that's a blunder. But winning probability is a nonlinear function of stockfish centipawns. A drop in 100 centipawns when you're up 15 points isn't a blunder. When the game was equal, it is.
Point is, by the time you know it's a blunder you already know something about the outcome of that move, that it swung the winning probability by more than 14%. So the analysis is kind of just measuring some function of winning probability and saying that it is highly correlated with winning probability.

So bad at chess that it’s genuinely upsetting at this point, I need some hope
If you want to improve make it your goal to play the best chess you can, not increase an arbitrary number. Watch YouTube series like John Bartholomew's "Climb the Rating Ladder" for some general insight into what you might be doing wrong. Read Irving Chernev's "Logical Chess: Move By Move" to see the thinking process of high level players. Do lots of puzzles (I like lichess.org for puzzles). And always analyze your games. When you analyze make it your goal to find at least two things you could have improved.
