In 1995, a small team of engineers unveiled a new programming language designed for flexibility, portability, and robustness. That language was Java. And three decades later, it remains one of the most influential technologies in the software world. Thank you for helping us celebrate #30YearsOfJava this past year. We look forward to many, many more years of pushing the boundaries of innovation and the pursuit of developer excellence. ❤️

JavaOne is over. And it was a really good one. Huge thanks to the Java DevRel team at Oracle. Chad Arimura, Sharat Chander, Heather Stephens, Nicolai Parlog, Lize Raes, Jim Grisanzio, Billy Korando, Ana-Maria Mihalceanu, José Paumard, Melissa Jacobus, Denys Makogon, David Delabassee, Crystal Sheldon You notice when people care about what they’re building here. For me, the best part was the conversations. Not the talks. The hallway track. Talking directly to the people working on Java. Getting their unfiltered view. Hearing how things actually work and where things are going. That’s the stuff you don’t get online. Also - very well organized. And yes, the food was great (not comparable to JavaOne from 10 years) I gave two talks around the Java ecosystem: The core idea was simple: Java can do a lot more than many people think. I showed how tools like OpenRewrite, Vaadin and EclipseStore help you move faster and get more out of your applications without throwing everything away. And then there was the ribbon game. Luiz Real and Ivar Grimstad took it seriously. Really seriously. Just look at their badges. Next stop is JCON Europe in April: europe.jcon.one The Oracle team will be there. If you want to have these kinds of conversations, that’s the place.

It was an honor to be among my fellow Brazilians over the past few days at #JavaOne

Final day at #JavaOne! Highlights: 30 yrs of Java 🎂 AI is now a daily dev tool 🤖 Startups pick Java to scale 📈 @brjavaman repping SouJava 🇧🇷 Meeting @BrianGoetz and the architects was the perfect finale. #JavaOne2026 #SoftwareEngineering
