Feeling incredibly grateful! 🙏 Together with my amazing @Oracle colleagues, we raised nearly $14,000 to support high-impact biomedical research into ME/CFS, the disease my partner is suffering from, through @weandme.bsky.social . 💪🤩 #OracleGiving #MECFS

Screenshot of $13,863 raised by 30 donors and matched by Oracle.

That was my total lunar eclipse today here in Zurich. There was a crowd of astrophotographers around. The moon was barely visible for 5 seconds, but the crowd was "ooooohhhh aaaahhh". I love these people.

Today is World ME/CFS day. My partner has been severely suffering from this disease for almost three years now. The care and research situation is really dire. It's so bad I even made a sign myself. Probably one of the hardest engineering challenges I had to tackle in a while.

GraalJS now supports Wasm module imports which leverage GraalWasm. Embedding the excellent Photon Rust library in JavaScript is now even simpler:

GraalPy, our Python runtime comes with lots of performance improvements, revamped native interop and a Gradle plugin for simple Python package embedding. Using a Python package from Java with Gradle is now as simple as this:

We've finally released the long awaited Bytecode DSL! Truffle now generates bytecode interpreters from AST-like specifications for you. ASTs are dead, long live bytecodes! All details here: github.com/oracle/graal...

Christian Humer @chumer.dev · 13/03/2025

I agree with you completely.

Today marks 10 years at Oracle Labs! 🎉 It has been great to watch GraalVM grow from a dream to a mature product. I've never been bored this entire time and there is no boredom in sight. Here’s to the next decade with the best colleagues!

Added more than 11 years ago :D To be fair the latest Valhalla proposal goes a bit further than what we have in Truffle ;-)

Good news everyone! 🎉 After two years of R&D, we've finally merged the Bytecode DSL into master! Truffle now generates bytecode interpreters from AST-like specifications for you. ASTs are dead, long live bytecodes! Check it out: github.com/oracle/graal...

Conceptual example of the Bytecode DSL. Use any parser you like, create operations using an AST-like builder with custom node-like operations. The DSL generates an automatic bytecode format with optimizations for you.

How do you get Java peeps that still use the classpath to use modules without them knowing? (hint: it is not simple)

Is there a special place in hell for people that do this?

Please don't forget to breathe during this exercise. Now repeat after me: This is fine. This does not need fixing. There are more important things to worry about... repeat 5 times...

Anyone has the correct codes? God damnit...

This is how it looks like when multiple object-inlined nodes get specialized with a single write in the IR. 🤩

How it feels to fix that last bug in Truffle's new node object inlining.

TIL that you can simulate the diffraction pattern of the James Webb Teleskope with a Fourier transform in log scale. This is where the spikes come from...

Ohoh. Eclipse 4.21 thinks all classes in org.graalvm.* contain JDK internal classes and added a default type filter which effectively breaks autocomplete for all GraalVM APIs. Please note and disable the new type filter. Hopefully this gets fixed...
