4-panel comic. (1) [Person 1 with ponytail flanked by person with short hair and another person speaking into microphone at podium] PERSON 1: In the early 2010s, researchers found that many major scientific results couldn’t be reproduced. (2) PERSON 1: Over a decade into the replication crisis, we wanted to see if today’s studies have become more robust. (3) PERSON 1: Unfortunately, our replication analysis has found exactly the same problems that those 2010s researchers did.

@lewurm.bsky.social I've heard you are an expert in both, git and mate. Maybe we should give it a try? 😅

What is git-mate and where can i get it!?

GPULlama3.java Brings GPU-Accelerated LLM Inference to Pure Java

The University of Manchester team extended @mukel.bsky.social's Llama3.java (github.com/mukel/llama3...) with GPU support via the GraalVM JIT and TornadoVM: www.infoq.com/news/2025/06...

Nicely done!👏

@graalvm.org for JDK 25 has been branched-off as well!

JDK 25 has been branched from the main line and is now in Rampdown Phase One: mail.openjdk.org/pipermail/jd...

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.

Exciting news for C and C++ developers! @clion_ide just joined the club of WebStorm, Rider, and RustRover and is free for non-commercial use. Learning, developing open-source projects, creating content, and hobby development are now more accessible than ever before!

✅ @graalvm.org Native Image
✅ Llama3.java
✅ Vector API, FFM API
✅ Apple Silicon ❤️

— `git clone github.com/mukel/llama3... `
— `sdk install java 25.ea.17-graal`
— `make native` (optionally preload a model for zero overhead)
— Profit!🚀

[GR-58659] [GR-58660] Add FFM Support for {darwin,linux}-aarch64 on SubstrateVM by graalvmbot · Pull Request #10856 · oracle/graal Adds support for AArch64 platforms. This is based on the x86_64 implementation and adapted accordingly.

You asked, we delivered: we merged FFM support in @graalvm.org Native Image on MacOS/AArch64!🚀😍
github.com/oracle/graal...
This means that you can now also build and run locally apps like github.com/mukel/llama3... (cc @stephanjanssen.be :))
Coming soon in GraalVM for JDK 25 EA builds!🎉

Yes, the below @sdkman.io command line is the perfect way to adopt to the latest Java 24👍

Happy IWD to all my fellow speakers, developers, and women all over the world. Keep changing the world for better ❤️

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!

Colored assembly with branch visualization

I was going through the binutils changelogs and I came across two great "new" features

Version 2.42 introduced `--visualize-jumps` and 2.40 introduced syntax highlighting with `--disassembler-color=MODE`

I really appreciate jump/branch visualization in disassemblers, makes life so much easier...

Big news today for a bunch of the open source projects I work with. github.blog/changelog/20... #opensource #arm

Wow native compilation of a #Java app with #Quarkus and #GraalVM on an Intel CPU is getting seriously fast 🚀! I clocked this one at 34 seconds and that's with running the compilation inside a container as well. Kudos to the @graalvm.org and @quarkus.io teams!

A great opportunity for anyone looking for an internship. @graalvm.org is a really interesting project touching a lot of system software concepts and is backed by a great research team!

Are you looking for a summer internship?👨‍🎓 Join our team on a mission to make all languages fast, and developers all over the world more productive!

Today I got to do some thinking about compiler IRs and finally solved a problem that has been vexing me for at least a dozen years:

Is it possible to directly interpret a sea-of-nodes graph efficiently (i.e. no schedule)? What does that even mean?

Yes Virginia, it's possible. It means max ILP.

One charger to rule them all!

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.
