Conferences

This was my second time speaking at IBM TechXchange. First time was at the inaugural event in 2023 located in Las Vegas with around 2000 attendees. At this year’s event in Orlando, it had grown to around 9000 attendees. New this year was that the Java community track was organised...

I had the pleasure of being invited to speak at Open Source Community Day 2025 in Madrid. This two-day event gathered attendees and speakers involved in EU research projects all over Europe. It is not my usual crowd, so it was interesting to see how this community works. I must...

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...

I tried to figure out how many editions of JCrete I have attended. Let’s just say that it’s been quite a few, and I enjoy is just as much every time I return. The community at JCrete is just incredible, the food is awesome. The only thing to wish for...
