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 20: A Sneak Peek on the Panama FFM API
Going to copy my Reddit comment over to HN because I think it's valuable:
---
One of the coolest things that's been worked on (by this same author, no less!) isn't even in the article!
Per has written a pretty-printer for MemorySegments and ByteBuffers that can hex-dump memory or render memory/buffers as their "struct" representations given some MemoryLayout.
You can also customize it with your own printers, it's wicked cool and helps so much to debug buffers when working with them.
https://github.com/openjdk/panama-foreign/pull/695
What do I mean by that? Have a look at this comment for an image of a raw memory structure layout I represented with MemoryLayout, and the pretty-print rendering of it:

Use JNI or are there other alternates?

Panama foreign function overhead - how can it be improved?
I am not using any special flag (is there one?) but the overhead seems quite high, especially considering the explanation on how these methods are compiled https://github.com/openjdk/panama-foreign/blob/foreign-jextract/doc/panama_ffi.md

Possible to use Kotlin/Native to call Win API from Kotlin/JVM?
https://github.com/openjdk/panama-foreign/blob/foreign-jextract/doc/panama_jextract.md ..look at these examples
- It’s happening guys!

JEP proposed to target JDK 18: 419: Foreign Function & Memory API (Second Incubator)
I found the full context for the change written up here https://github.com/openjdk/panama-foreign/pull/554

Will scala-native run without a garbage collector?
Incentive for JVM devs? We know that C interoperability, malloc, free, structs are already supported on JVM natively since Java 14 with project panama's foreign-memory-api without JNI. I've been using sun.misc.Unsafe since Java8 and also LWJGL's C API.

Poor gRPC performance on test - help needed
SayHello, GetUser, and Sum differ only by payload size. Sum is the simplest one - (int, int) -> int, GetUser is (long) -> User (medium payload), and SayHello uses exactly the same payload as this test: https://github.com/LesnyRumcajs/grpc_bench/tree/master/dotnet_grpc_bench

2023-06-25 gRPC benchmark results
This is correct. The problem is not with the benchmark itself but with the implementation. If you look at the result, you can see that even with 6 "allowed" CPUs, the vertx server utilizes less than 100%. Apparently, the current vertx implementation (the one implemented in https://github.com/LesnyRumcajs/grpc_bench/tree/master/java_vertx_grpc_bench) is single-threaded or has some other limitation.
Another iteration of grpc_bench!

Why does C#/.NET is in demand in Philippines especially in BGC? How about PHP?
Because it's fast and runs on Windows, Linux, and MacOS

Another two cents about the current situation with the Scala user base and economics.
In general though, akka/pekko-streams are known to be one of the fastest implementations out there. Their grpc client for example even beats languages like Rust (see https://www.lightbend.com/blog/akka-grpc-update-delivers-1200-percent-performance-improvement and https://github.com/LesnyRumcajs/grpc_bench/wiki/2022-03-15-bench-results).
-
What is the current status of Akka in your organisation?
The whole point I was making is at least up until 8 months ago (at best, I can't commend on the stability/maturity/performance of shardcake) Akka was the only mature library/ecosystem solving this problem with also a very strong focus on performance (for example still to this day, akka/pekko-grpc is generally one of the fastest grpc implementations I am aware of, its even beating rust if you have at least 2 cores (see https://github.com/LesnyRumcajs/grpc_bench/wiki/2022-03-15-bench-results)

QuickBuffers 1.1 released
It would be interesting to create a new java benchmark with your implementation.

Also worth checking out the gRPC benchmarks: https://github.com/LesnyRumcajs/grpc_bench/discussions/284
dotnet is up there with Rust.
