I realized that after I saw the conference photos today 😭.

A quick pre-talk selfie captured by @0.5ritter.de got its own behind the scenes by the amazing @ddoutsiopoulos.bsky.social 😆!

And @devoxx.com ends with an epic talk presented by @lizeraes.bsky.social: leveling up #langchain4j apps for production!

Awesome demo included!

Watching @brianvermeer.nl talking @devoxx.com about "advanced" prompt injection in AI and LLM's...

By just repeating the same prompt twenty times, it'll suddenly comply to your malicious prompt. Yes!

The best #Devoxx session (in my book) is about to start: Ask the Architects. Bring your questions about Java and the OpenJDK architects will answer them. See you in five!

At @devoxx.com listening to talks on Pattern Matching, Serialization and Ask the Architects. There is a lot of research bubbling away under the surface by the excellent #Java team.

Supercharge your JVM performance with Project Leyden and Spring Boot Many modern applications and tools rely on Java. Yet, their startup time and time-to-peak performance remain challenging, especially for microservices and Kubernetes workloads that require fast scaling and responsiveness. Project Leyden, an ambitious OpenJDK initiative, aims to overcome these performance bottlenecks. In this session, Ana and Moritz showed how you can take advantage of Leyden’s optimizations using Java 25 and Spring Boot. You also got practical techniques you can apply today, along with a peek into the ongoing work inside Leyden and what that means for the performance of your Java application. - Download as a PDF or view online for free

Thank you to everyone who joined our session on boosting Java performance with Project Leyden, Java 25, and Spring Boot! 🚀

@0.5ritter.de and I hope that you will apply the optimizations and tips we shared today. The slides we used:

Watching @0.5ritter.de and @ammbra1508.bsky.social preparing and doing training runs to improve Spring boot startup and warm-up time with Project Leyden and Java 25. 🚀

But wait... No AI and agents required? Am I still @devoxx.com 😊?

#Devoxx #Java #performance #impressive

Nice to see JLink getting some love from @ammbra1508.bsky.social at #Devoxx

Great talk on Leyden and Spring Boot from @ammbra1508.bsky.social and @0.5ritter.de #Devoxx

Still in top 5 of the week @maritvandijk.bsky.social 🤩🥳🥳🥳!!!

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.
