Yesterday was the last day of #JCON2026. On the plane back home, I was thinking what metaphor would best describe it. And then it clicked - a big family reunion! In a family where people like each other, of course😁 Thank you for having me ❤️

🥰🥰

I hope everyone knows that yesterday the latest updates of #OpenJDK have been released…so go ahead, download and update your #Java installations…now 😁

After so many online encounters, first time meeting the amazing @hansolo.eu and @brunoborges.bsky.social in person, can you believe it?😅🥰

The amazing @ddoutsiopoulos.bsky.social knows good frames or me showing off my new tattoos at Spring I/O 2026🥰 (and a big fish, apparently😅)
