My talk ‘Making sense of vector databases’ was in the Top 10 best rated talks at #JFall 2025. 🍁
Thank you @nljug.bsky.social for the opportunity 🙏 and to all the people who joined the session and showed so much love! 🧡

Feeling proud to be in the company of these legends!

J-Fall 2025: A Day to Remember - NLJUG - Nederlandse Java User Group On November 6, 2025, the Java community came together in Ede for another great edition of J-Fall. Th

It's been more than a month since #JFall, but it's nice to go over the memories. Especially when you see your name in the Top 10 of best-rated speakers 😊

Do I need that to feel like a good speaker? No! But it is flattering anyway, so thanks to everyone who rated my talk!

Me speaking at JFall 2025

Had an amazing time at @nljug.bsky.social #JFall 🍁 about 3 weeks ago! 🎉 It’s one of those conferences that feels like a warm community gathering! Gave my talk “Making Sense of Vector Databases” to a packed room: great energy & feedback! Big thanks to the organizers for making it awesome as always! 🙏

At the @devoxx.com and #JFall conferences, I interviewed speakers and attendees for the @foojay.io #Podcast. In part 1, you'll learn more about ongoing #OpenJDK projects and #TornadoVM. Watch on YouTube or listen in your favorite podcast app: www.youtube.com/watch?v=Srxy...

Had an amazing time at #JFall 🍁 Spoke about “Framework-Agnostic Development with Java.” Thanks to everyone who packed the room and brought the energy! Always special to reconnect with friends and meet new faces.

Great edition of @nljug.bsky.social #jfall again this year!

But… I don't think I saw a single speaker run a version of Java that wasn't at least 1.5 years old. Set a good example, install JDK updates! #security

Current latest (Oct '25) LTS versions:

- 25.0.1
- 21.0.9
- 17.0.17
- 11.0.29

I gave my workshop at #jfall2025 #jfall today. It was a success, a packed room and people working through my AI challenges for 2 hours. If you attended you might like the slides, they are available on my talks page: arjenwiersma.nl/talks/

As always, #JFall was a blast - thanks for having me and letting me tell people about the latest #Java features. 🙏

Goodbye #jfall ! It was a fun day. Did you spot the Blåhaj?

Thank you for attending our #JFall talk on project Babylon. If you feel tempted to launch or even define AI models in Java, or if you have parellellizable code that you'd live to run on GPU, have a look and try it out. Your feedback is super valuable!

Na een korte nacht, gevolgd door een hele dag #Java-praat op #JFall, zoals elk jaar na een snelle hap weer snel door naar #LeGuessWho.

Laughing here in the back at @maritvandijk.bsky.social and @peterhilton.bsky.social talk at #JFall 😂!!!

Indeed essential programming jokes collected by these two!

Nice to see some familiar faces & meet new ones over at #JFall !

Always inspiring to speak to folks who care about Open Source. It really makes working on #radicle worth it all the more!!

Thanks to #NLJUG for organising such a large event and being great hosts!

Hope to be back again some day! o/

Writing GPU-Ready AI Models in Pure Java with Babylon Project Babylon introduces the experimental Code Reflection technology that lets you define machine learning logic in plain Java code, without needing Python or external model files. It then uses Foreign Function and Memory (FFM) API to connect your code to native runtimes like ONNX Runtime for fast inference, including GPU acceleration. Furthermore, the Heterogeneous Accelerator Toolkit (HAT) provides a developer-facing programming model for writing and composing compute kernels, which can be more broadly applied-allowing Java libraries to seamlessly harness GPU power for high-performance computing tasks.

Thank you to everyone that attended our talk on writing #AI models in pure #Java 🥳 !!!

The slides @lizeraes.bsky.social and I used at #JFall are available below, but you can always connect with us and ask more questions on what we presented 😇!!!
