In this episode of the Foojay Podcast, we're bringing you something special: a full batch of hallway-track conversations recorded live at VoxxedDays Amsterdam.
Fifteen guests, one conference, and one theme that kept coming back, whether we planned it or not: Java has grown up quietly, steadily, and in ways that still surprise people who haven't looked lately. We talked about migrating between versions, new features in the latest Java releases, authorization done right, AI-assisted coding, cryptography, containers, open-source contributions, GDPR data experiments, and, yes, the things people hate about Java but secretly love.
I spoke with Ko Turk, who organized this very conference, Johannes Bechberger, Lutske de Leeuw, Aicha Laafia, Marit van Dijk, Adele Carpenter, Patrick Baumgartner, Sohan Maheshwar, Jeroen Egelmeers, Erwin Manders, Alexander Shopov, Maarten Verburg, Arjan Tijms, Joost Kaan, and Stephan Janssen.
That's a lot of people. That's a lot of opinions. And somehow, they mostly agree: update your JDK, read your code, and please talk to your actual users.
