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.

Java 21: The Nice, the Meh, and the Momentous
It is not. Blocking IO (with some exceptions mentioned in the JEP) will automatically be translated by the runtime into non-blocking IO when it occurs on virtual threads, and no OS threads will be blocked. You can have a million threads blocking on a million sockets (obviously without creating a million OS threads): https://github.com/ebarlas/project-loom-c5m
You can't do that with thread pools. You could achieve that scalability with async code, but then observability tools will not be able to track the IO operations and who initiated them, but with virtual threads you'll see exactly what business operation is doing what IO and why.

Don’t call it a comeback: Why Java is still champ
That might change in JDK 21 (with virtual threads). See this https://github.com/ebarlas/project-loom-c5m . It achieve 5 million persistent connections (again depends on the server capacity and kernal tuning) using normal simple blocking code (https://github.com/ebarlas/project-loom-c5m/blob/main/src/main/java/loomtest/EchoServer.java) . It's a far better better programming model compared to JS async/await.

Not really, here it is winning hands down over Swift's ARC implementation.

Blog post: My perspective on RAII and memory management in C++ and Rust
GC'd languages are designed to leverage GCs, meaning they usually allocate a lot. Some of the more recent ones (C#, Go) have ways around it or to limit it, but in your average GC'd language you have to really bend yourself out of shape to limit allocations (IIRC the Ixy effort / study / thing never managed to make the Java hotpath allocation-free).

What are my prospects in web programming, if I don't like JS?
like not-even-in-the-same-ballpark faster. In this realworld example (userspace network drivers in managed languages) JS manages about 20-30% of native code performance, python iirc is below 1%

Don’t call it a comeback: Why Java is still champ
- Support for generic-aware value types (struct vs. class) and low-level features like stackalloc: very valuable for high-performance scenarios and native FFI. See for instance https://github.com/ixy-languages/ixy-languages. In comparison, Java doesn't even have unsigned integers. Yes, Project Valhalla is coming someday.
As well, debatable to some folks, but: properties (get/set); operator overloading; LINQ > Java streams; extension methods; default parameters; collection initializers; tuples; nullable reference types; a dozen smaller features

Why did you switch from another language to Rust? Do you regret not learning it earlier?
