After a while working on this, it is finally out!

@rustlang integrated with #Android and @kotlin.

If you want to notarize your Java app with native libraries for Mac OS.
#notarize #java #jni #macos

I do love #golang #cgo for interfacing to non-go (C) library code and system features. Much nicer than #jni and easy to wrap both C strings and structs, and doing so both ways. This made it simple to use #coventry ipc from apollo as well as to run the libeXosip2 stack under go.

I have been consulting the ancient texts

#java #jni

Project Panama will enhance the native code handling in Java. I'm really excited about this addition to the #JVM since my current project uses a lot of #JNI to parse and memory map media files, run GPU accelerated face detection and use netty native bindings for epoll / io_uring.

Maybe we'll see a lot more native enabled projects in the future of #Java

I'm using #JNI to create #Scala bindings for a #Rust library. Bad idea?

@cryptomator That's what an implementation via libappindicator does look like on a vanilla #GNOME DE.

The implementation could be done via #JNI or #JNA, but I decided for the #ProjectPanama FFI as a state of the art approach.

Reading a 25 year old engineering book on #Java #JNI that is still the most up-to-date book on the subject. Native development is wild.

#Cprogramming

Recently I discovered setjmp/longjmp (a non-local goto) which allowed me to dynamically bypass an indefinitely blocking (external) library call (in my case a #JNI method on #Android ).

In conjunction with pthread_cond_timedwait(), the block times out and makes a non-local goto (jump) to the code right before the blocked call, then executes a normal goto past the blocked call. Sounds a bit of a hack..I might finesse a bit.

Bingo! This is another one of my highlights moments!

Just a little research and hacking of the #Rust/Cargo build process, save my life of building the library of #signal-cli : #zkgroup.

I should appreciate myself for being one second more patient in tackling the build issue on #openbsd/#netbsd, before I give up.

Actually the author of #jni had already fixed the issue while zkgroup had not been adopted yet. 😏
