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?

I had a great experience with Scala and hopefully it will get more popular
scala has 2 healthy and pretty complete lib ecosystems : check out typelevel and ZIO. Both are FP oriented, which might not be your cup of tea at first glance but I would encourage you to try em out ! Softest introduction would be to start with the typelevel cats library and build up from there. The excellent Scala with Cats will ease you softly into an FP mindset. It's a bit dated and for scala 2 only but translating to Scala 3 is a very good exercise if you feel so inclined !

Is it prudent to use Scala for anything new?
Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.
Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

Is Parallel Programming Hard, and, If So, What Can You Do About It? [pdf]
I use ZIO (http://zio.dev) for Scala which makes parallel programming trivial.
Wraps different styles of asynchronicity e.g. callbacks, futures, fibers into one coherent model. And has excellent resource management so you can be sure that when you are forking a task that it will always clean up after itself.
Have yet to see anything that comes close whilst still being practical i.e. you can leverage the very large ecosystem of Java libraries.

40x Faster! We rewrote our project with Rust!
The one advantage Rust has over Scala is that it detects data races at compile time, and that's a big time saver if you use low level thread synchronization. However, if you write pure FP code with ZIO or Cats Effect that's basically a non-issue anyway.
