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.

Android predictive back support
I am migrating XF app into MAUI and writing a simple Navigation framework because Prism doesn't work well and I didn't use anything advanced anyway. So, I am surfing the code of MAUI to intercept all the back buttons, etc. I haven't found a single mention of apis related to predictive back "RegisterOnBackInvokedCallback", "OnBackInvokedDispatcher", "OnBackPressedDispatcher", "AddCallback", "android:enableOnBackInvokedCallback" Also I don't see any issue on github that would say "Support Android Predictive back". Only one kinda related https://github.com/dotnet/maui/issues/8680

I do share your skepticism of Microsoft, but it looks like the economics and cash flow dynamics have changed drastically after the advent of the cloud.
Microsoft is more focused on getting developers onto its ecosystem and help them with open source projects with the hope that they will use its Azure cloud services and bring in the money.
My skepticism is a bit relaxed now and I have no qualms using .NET.
I hope I am not wrong.

.NET 8 – .NET Blog
It's a bit of a hit and miss as of today. CLI, back-end and natively compiled libraries (think dll/so/dylib or even .lib/.a - you can statically link NAOT binaries into other "unmanaged" code) work best, GUI - requires more work.
Avalonia[0] and MAUI[1] have known working templates with it, but YMMV.

What's New in Final RC for .NET 8, .NET MAUI, Asp.net Core and EF8
While this is the quite endorsed by the community: https://github.com/dotnet/maui/discussions/339
I think the fundamental issue is that desktop Linux is way too fragmented. Not only just GTK2/3 and Qt but you have GNOME, KDE, XFCE, Cinnamon and then you have X11, Xorg, Wayland...
To be honest, all those craps are why desktop Linux never took off. I'm very safe to say MAUI for Linux will eventually renders components off its own using framebuffer and hardware acceleration APIs such as OpenGL or Vulkan just because of the market fragmentations...
If desktop Linux truly wants to get the attention, it will need to unify. Fixing dependency hell using Flatpak is the right direction.
There is an existing old fork of MAUI for Linux that uses GTK: https://github.com/jsuarezruiz/maui-linux

Every other tab in Shell doesn't show Shell.TitleView on Android
First I came across this Github issue: https://github.com/dotnet/maui/issues/9687 - According to this issue, this is a known bug for MAUI iOS, but it works OK for MAUI Android. As I said, I target Android only and I have the exact same issue. It's apparantly fixed with some of the latest versions for MAUI but the problem still occurs to me even with MAUI version:

Bindable properties issue with Custom controls
I saw this and tried to imitate (ofc my lack of experience wouldn't allow me to do it in the exact way). Already found some documentation that allowed to understand better. Thanks for the insigh.
