MySQL Belgian Days and FOSDEM 2026: My Impressions
First of all, I want to say a huge thank you to Frederic Descamps and the entire team who worked on the MySQL Belgian Days. I was thrilled to see the high number of presentations and the excellent quality across the board. We had two rooms packed with attendees, and the event was simply great.
