On April 3rd, the first [VoxxedDays event in Amsterdam](https://amsterdam.voxxeddays.com/) took place. VoxxedDays are tech events organized by local community groups, with support from the Devoxx team. Geertjan Wielenga brought along a camera and microphone and spoke with many of the attendees.

This is the first Foojay podcast ever to feature more than 20 guests! Geertjan asked the same two questions to many of conference visitors: "Tell us who you are and what excites you about the technology landscape?" and "What are two tips or insights you'd like to share?"

As you might expect, there's a lot of talk about AI and machine learning, but you'll also hear about new Java features, profiling, open source, security, code reviews, and much more!
