2025 Live Stream CyberJAR

Chatting about Java, JavaFX, and Experiments on the Raspberry Pi

20250828 - Live Stream with Catherine Edelveis (CyberJAR) and Frank Delporte

Java on a tiny board? JavaFX on touchscreens? In this session, Catherine is joined by Frank Delporte, Java Champion and author of ‘Getting started with Java on Raspberry Pi,’ to explore how JavaFX fits into modern IoT/embedded workflows on Raspberry Pi.

Who It’s For

• Java devs curious about embedded UI
• Tinkerers who like shiny pixels and blinking LEDs
• Anyone who’s ever said “I could build that…” and then… didn’t (today’s your day)
