Thank you #JFall programme committee for accepting my talk proposal! 🙏 So happy to be speaking at one of the best #Java conferences! ☕️ 🤩 @nljug.bsky.social

Project Loom brings lightweight concurrency to Java. Virtual Threads, Structured Concurrency, Scoped Values — @balarawool.bsky.social shows how the pieces fit together in the latest IntelliJ IDEA Tech Talks 👇 youtu.be/2L7zLdHeyY0

Excited to be at @devoxx.com again! 🤩 Thank you to the programming committee! 🙏

Eleven days ago, I helped run the incredible #JSpring event at Kinepolis in Utrecht! 🇳🇱 We were completely sold out with over 800 attendees and 30+ amazing speakers sharing their knowledge. Huge thanks to everyone who showed up and made it so special! ⚡️

Hey #JSpring, want to explore virtual threads 🧵 and other Project Loom features 💻 Join me in Room 10 at 11:35 for some live demos 🧑‍💻

Had fun recording a tech talks video with @balarawool.bsky.social at the JetBrains office yesterday.

It was nice to catch up with @sharatchander.bsky.social once again @jcon.one Thank you for all the work you have done for the #Java community! Hope to see you soon again ❤️

Thank you @richard.fichtner.dev for this token. I really appreciate the gesture! 🙏 @jcon.one

It was a delight to catch up with @piotrprz.bsky.social yesterday @jcon.one Look at our Polish smiles! Ko Turk, @rijosam.com @fmartin.ch

Due to personal reasons, I’ll not be able to join VoxxedDays Amsterdam. I’m really bummed to miss it as it is such a great conference! Although this was a last minute change, the organizers were very supportive and understanding! Thanks @amsterdam.voxxeddays.com and see you all next time! 🙏

How does #Java Vector API accelerate parallelizable computations? I explored it in my new article (with an example): Estimating value of pi (π) using Monte Carlo Simulation and Vector API Read it here: www.balarawool.me/Vector-API-P...

An evening filled with fun, knowledge, architecture and performance @utrechtjug.bsky.social with Michel Schudel and @ammbra1508.bsky.social

A fun “20 Questions” game using @spring-ai.bsky.social github.com/balkrishnara... Features include: * Integration with LLM * ChatClient * Prompt separation (system and user) * Memory for chat (MessageWindowChatMemory) * Type-safe responses * Spring Retry integration (for invalid responses)

I’ll be speaking @jfokus.se 2026 about Project Loom. ☕️ 🧵There are so many awesome speakers and so many amazing talks/ workshops. 🧑‍💻👩‍💻 And only last few tickets left, so please hurry up and get yours at: jfokus.se/register.html

Happy to share that I’m in the Top 3% of the most active speakers on @sessionize.com for 2025! 🤩 A huge thank‑you to all the conference organizers who continuously put their trust in me, the audiences who show up with curiosity, and the amazing #Java community that keeps inspiring me every day. 🙏

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!

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...
