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:

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!

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.

Use JNI or are there other alternates?
I have been thinking about couple of utilities I want to make. And I have programmed in Java and _very very_ little in JNI. I wanted to know based on actual experiences, is it really bad since there seem to be some tools out there. This is the first one I came across: https://github.com/spotify/JniHelpers
What are some alternatives?
JNA - Java Native Access
LWJGL - LWJGL is a Java library that enables cross-platform access to popular native APIs useful in the development of graphics (OpenGL, Vulkan, bgfx), audio (OpenAL, Opus), parallel computing (OpenCL, CUDA) and XR (OpenVR, LibOVR, OpenXR) applications.
SWIG - SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.
jextract - https://openjdk.org/projects/code-tools
win32metadata - Tooling to generate metadata for Win32 APIs in the Windows SDK.
rust-bindgen - Automatically generates Rust FFI bindings to C (and some C++) libraries.
Introducing .NET Multi-platform App UI (MAUI) - .NET MAUI is the .NET Multi-platform App UI, a framework for building native device applications spanning mobile, tablet, and desktop.
