It just hit me that Spring I/O 2026 is ONLY a week away😲🤩
I experience a funny mix of excitement at reuniting with all my friends and... Anxiety.
The latter one because I'll have to fight
@asm0di0
on stage defending JPA case vs jOOQ, and my opponent is a hell of a fighter😂
This is a very important milestone for us! Thank you everyone for watching and stay tuned ❤️

Have been so careful about keeping my NeuroWatch demo clean and up-to-date that I have nothing to showcase when explaining how to manage CVEs in application deps. Need to add a vulnerable dep on purpose, oh my😅
Java is powerful, but its community is what makes it special💚
This Thursday, I’ll go live with @yourjavaguy.bsky.social to talk about building a thriving Java community, supporting newcomers, sharing knowledge, and helping each other grow.
Come hang out with us!

Behold: the first-ever list of news outlets that have banned generative AI in their reporting. As of today, this is literally information that you cannot find on Google.
My goal is to fill the starter pack, so please send over suggestions with supporting evidence!

Slop is the perfect word to describe the low-quality, high-volume, AI-generated content being thrown around.
If you don't have time to write it, I don't have time to read it.
Really?? Cool, thanks for the heads-up!
