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.

Overhead of Returning Optional Values in Java and Rust
I reran the benchmarks with the latest Valhalla branch [1] and added a test that used OptionalLong instead of Optional.
Without Valhalla
OptionBenchmark.sumSimple avgt 5 328,110 us/op
OptionBenchmark.sumNulls avgt 5 570,800 us/op
OptionBenchmark.sumOptional avgt 5 2223,887 us/op
OptionBenchmark.sumOptionalLong avgt 5 1201,987 us/op
With Valhalla
OptionBenchmark.sumSimpleValhalla avgt 5 327,927 us/op
OptionBenchmark.sumNullsValhalla avgt 5 584,967 us/op
OptionBenchmark.sumOptionalLongValhalla avgt 5 326,949 us/op
OptionBenchmark.sumOptionalValhalla avgt 5 572,833 us/op
OptionalLong is now as fast as the simple sum. And SumOptional is now identical so SumNulls

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
