Conferences

The second edition of the Jalapeño unconference was held in Cancun, Mexico September 13-14. The intention by having it this weekend was to get the Mexican Java community to be able to bring their family for the long weekend since September 15 is a holiday in Mexico. This didn’t really...

Community Over Code is a very community oriented conference, and the 2025 edition was no exception. It is by and for the ASF committers and projects. The usual greeting phrase is not “What is your name?” , “Where are you from?” ,or “Where do you work?”, but rather “What (Apache)...

It’s been three years since last time I spoke at JavaZone, so it was very good to be back this year. The usual venue in downtown Oslo is under renovation, so the entire conference had relocated to Lillestrøm. It is just a 10 minute train ride north of Oslo, so...

My second and last stop on the LAOUC Community Tour 2025 was São Paulo. This event, GUOB Tech Day 2025 was organised by the Brazilian Oracle User Group (GUOB) and about 300 attendees showed up. I presented a talk titled The Past, Present, and Future of Enterprise Java as one...

WeAreDevelopers World Congress in Berlin is a massive event. It is located at the huge Messe Berlin with two exhibition halls, and 13 parallel tracks. Most of the stages are located near, or in the expo. Usually, I don’t like this much since there is so much noice, even with...

I’m back in Tokyo again. This time for JJUG CCC 2025 Spring. This Cross Community Conference (CCC) is organised in twice a year and attracts around 1000 attendees every time. I was a speaker at the Fall edition last November, and now again on the Spring edition. Most of the...

Spring I/O 2025 was a great experience! It is an extremely well-organized conference with an awesome community. It was my second time as a speaker, and I will definitely send talk abstracts to the upcoming editions as well. It does not hurt that it is organized in Barcelona in May...

JCON Europe 2025 was great! Period! It is such a flawlessly organized conference with an ever present community spirit. This year was maybe even more special than usual because of the 30 Years of Java celebrations. Eclipse Foundation had a booth where we featured the Jakarta EE, Adoptium, and Eclipse...
