I wanted a small tool to graphically manage ADF disk images. There's a Python library to work with them on the commandline. Whipped up a quick Java UI with @jbangdev using the #graalpy template and got myself a standalone native app thanks to @graalvm native image :)

We run the tests of ~600 PyPI packages every day to catch #GraalPy regressions and generate compatibility tickets for ourselves - a lot of stuff "just works" these days and we're working hard to match CPython: github.com/oracle/graalpytho… #graalvm

Years ago github.com/Baekalfen/PyBoy had to rewrite code to Cython to provide enough performance on CPython. Today, GraalPy can JIT the pure Python to within a few percent of the natively compiled Cython code (demo Gejmbåj by Snorpung) #graalvm #graalpy

Want to quickly call some Python code from your Java tool? Thanks to @maxandersen's help, you can now do it with @jbangdev, too. Also works with @GraalVM Native Image :) #graalpy #graalvm ➡️github.com/timfel/graalpy-jb…

How do other people deploy their pygames? With GraalPy 23.1, it can all be in single binary file, ready to run. Try "graalpy -m standalone --help" #graalpy #graalvm
