Foojay community members and beyond discuss embedded Java:

• James Gosling, creator of Java and embedded enthusiast. Distinguished engineer of AWS GreenGrass and former Liquid Robotics, an autonomous ocean vehicle powered by water.
• Frank Delporte, engineer with Toadi, an autonomous lawn-mowing robot (no wires) and Pi4J contributor of Raspberry-pi based robots.
• Johan Vos, founder of Gluon, helping make fully cross-platform applications where a single JavaFX codebase runs natively on embedded, iOS, Android, PCs, and browsers.
• Erik Costlow, developer relations for Contrast Security, locating security flaws in backend systems. Developer of home fuel/gas sensors.

Topics:

• Java in Education: Combining Java with Rasperry Pi and the Pi4J Library
• Discussion topics including:
  • How Java was used in the ocean and how it makes complex problems possible.
  • The speed of garbage collectors versus the speed of shark attacks (GC wins).
  • Quick prototypes with Raspberry Pi, scaling through AWS GreenGrass.

Foojay community members discuss the modernization of Jakarta EE applications from the older Java EE form, including backwards-compatibility, as well as forwards-excitement about cool new developments like Microprofile.

Guests:

• Rudy De Busscher, product manager of Payara and EE contributor.
• Josh Juneau, consultant and author of Jakarta EE Recipes.
• Ivar Grimstad, Jakarta EE Advocate for the Eclipse Foundation.
• Erik Costlow, Developer Relations for Contrast Security to secure Java/Jakarta EE applications.

In this podcast, we explore the topic of why there are so many JDKs, how are they the same, and how they are different. We balance the Java perspective with a special guest from the Rust foundation to learn how a peer ecosystem works.

Quick summary—the role of Java as a central system runtime lead to multiple implementations and the companies that make different distributions offer support and sponsor different work. For example Azul and Microsoft worked on Apple M1, and Bellsoft and Microsoft worked on Alpine Musl. All JREs are compatible through the TCK and vendors work together on security patches for the entire ecosystem.

Guests:

• Simon Ritter, Deputy CTO of Azul Systems, making the Azul Platform, including the Azul Zulu builds of OpenJDK.
• Dmitry Chuyko, Senior Performance Engineer of Bellsoft, making the Liberica builds of OpenJDK.
• Bruno Borges, Product Manager Microsoft, making the Microsoft builds of OpenJDK and Temurin, Adoptium's builds of OpenJDK.
• Ashley Williams, founder and open-source strategist for the Rust Foundation.
• Erik Costlow, Developer Relations for Contrast Security, securing Java and non-Java applications.
