Looks great!

I think I found a bug though. If you go straight to a page like sdkman.io/jdks/graal/, I get a broken page:

Excited to be back at @Devoxx Belgium—this year talking about @graalvm.org and #WebAssembly! Don’t miss what’s next for Java & Wasm. 🙂

Looking for tips & tricks for @graalvm.org and Graal Languages in @intellijidea.com?

Join me at IntelliJ IDEA Conf '25 to learn how to use it to:
🌱 Compile, monitor, and debug native images
🐍 Embed Python, WebAssembly, and more in your Java apps

👉 Agenda at lp.jetbrains.com/intellij-ide...

Did you know that #GraalPy is nicely integrated into
@jbang.dev? 🐍☕️

✅ Use Python packages in #Java
✅ Support for Python 3
✅ Smooth interoperability via Java interfaces

Our "javac on #WebAssembly" demo (and code!) for #WasmIO25 is up on GitHub in case you want to play with the new Wasm backend for @graalvm.org! 🚀

More details to follow soon!

"Hello from #WebAssembly generated with @graalvm.org!" 👀

(And yes, we can run more than a HelloWorld program 🤓)

More at #WasmIO25 tomorrow: 2025.wasm.io/sessions/the...

This is me debugging a Rust library compiled to Wasm and embedded in a @micronautfw.bsky.social microservice in @intellijidea.com: Compile with debug info, enable the Chrome Inspector for #GraalJS and #GraalWasm, and attach to the process. 🤓

Will share more details at #WasmIO later this month!

We just merged the current status of the upcoming JDWP support for @graalvm.org Native Image! 🥳

This will soon provide developers with the same debugging experience they are used to in Java, but for native images! Stay tuned for more details.

The free Ampere resources on Oracle Cloud are enough for me to set up even two runners that can build #TruffleSqueak in parallel!

Did you know that #GraalPy makes it easy to create interactive SVG charts with Pygal in your @micronautfw.bsky.social or #SpringBoot projects? 📊🐍

Initial support for jcmd is going to land in #GraalVM Native Image very soon! 🥳

This will bring diagnostics and monitoring of native images even closer to the HotSpot experience. JFR, heap dumps and thread dumps, JMX, and NMT are already available!
