    Update Your JDK, Read More Code, and Talk to Your Users: Interviews From VoxxedDays Amsterdam (#93)

    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.

    Java 26 Is Here: What's New, What's Gone, and Why It Matters in 2026 (#92)

    Welcome to another episode of the Foojay Podcast! In this episode, we're talking about Java 26, released on March 17 in the year 26. Again, right on schedule with Java's six-month release cadence. Now, Java 26 is not a Long Term Support (LTS) release; that was Java 25. But don't let that fool you into thinking there's nothing interesting here. This release brings ten JDK Enhancement Proposals (JEPs). They cover everything from performance improvements to long-overdue cleanups. Of those ten JEPS, five are new features, and we also get five preview/incubator features.

    28 FEB

    25 Years of IntelliJ IDEA: The IDE That Grew Up With Java

    In this Foojay Podcast, we're celebrating a major milestone in Java development history: 25 years of IntelliJ IDEA. Think about it: IntelliJ IDEA launched in 2000, and since then, it has become the go-to IDE for millions of Java developers worldwide. From its revolutionary code completion and refactoring tools to AI-powered features and the recent unified Community and Ultimate release, IntelliJ has shaped how we write Java, and keeps reinventing itself to stay ahead. For this episode, I'm joined by three people from the JetBrains team who know this story inside and out. Marit van Dijk, developer advocate and contributor to the Foojay community. Anton Arhipov, also a developer advocate at JetBrains. And Dmitry Jemerov, who has been part of the IntelliJ IDEA story for a very long time.

  4. From Java 21 to 25: The Features That Changed Everything (#90)

    14 FEB

    From Java 21 to 25: The Features That Changed Everything (#90)

    Every six months, we get a new version of Java. Java 26 is just around the corner and will be released soon. But most companies stick to LTS (Long-Term Support) versions, which are maintained and receive security updates for many more years. Versions 8, 11, 17, 21, and 25 are such LTS versions. Hopefully, most of your systems are already on the latest versions and you are not stuck on 8 or earlier. As a reminder, 8 was released in 2014, so much has changed since then.If you are doubting moving from 21 to 25, or even from an earlier version to the latest LTS, this podcast is for you! Together with Jakob Jenkov, we discussed the most important changes, and this episode includes a few quotes from interviews recorded at conferences last year.

    From Code to Stage: Organizing Conferences and Finding Your Voice as a Speaker (#88)

    What turns a nervous first-timer into a confident conference speaker? Let's find out. This the last Foojay Podcast of 2025 and also the last one with interviews recorded at the Devoxx and JFall conferences. Maybe you're already thinking about your goals for 2026: organizing a meetup, submitting your first conference talk, or taking a bigger role in the Java community. If that sounds like you, this episode is for you. I talked with the people behind these conferences and developers at different stages of their speaking journey. At Devoxx, I spoke with Stephan Janssen, who has been organizing Devoxx for 20 years, Susanne Pieterse, about what makes conferences valuable for learning, and Daniël Floor, a developer just starting out with public speaking. At JFall, I caught up with organizers Martin Smelt and Brian Vermeer, Berwout de Vries Robles, who coaches new speakers, and Annelore Egger about her journey from developer to conference speaker. You'll hear practical advice about what makes a good CFP, why conference organizers actively want new speakers, and how the Java community is set up to help you get started. Whether you're thinking about submitting your first talk or curious about what goes into organizing a conference, there's something here for you. 00:00 Introduction of topic and guests 01:33 Stephan Janssen https://www.linkedin.com/in/stephanjanssen/ Devoxx Organizer07:03 Martin Smelt https://www.linkedin.com/in/martin-paul-smelt-8b699a8/JFall Organizer 13:27 Brian Vermeer https://www.linkedin.com/in/brianvermeer/JFall Organizer and speakerTips for speakers, writing a CFPJoin a JUG! 21:02 Annelore Egger https://www.linkedin.com/in/anneloredev/How to become a speaker27:43 Daniël Floor https://www.linkedin.com/in/dani%C3%ABl-floor-266652208/Taking the first steps into public speakingFinding your speaking topic31:28 Berwout de Vries Robles https://www.linkedin.com/in/berwout-de-vries-robles/Tips for speakersPropose a talk to speak at a JUG37:08 Susanne Pieterse https://www.linkedin.com/in/susannepieterse/Learning at conferences, RAG, and other topicsMeeting and talking to the presenters and specialists at a conferenceCO-organizer of ML Con and DevOpsCon in Amsterdamhttps://mlconference.ai/https://devopscon.io/amsterdam/41:20 Conclusion

    The Human Side of Development: Career Growth, Staying Healthy, and Why People Matter More Than AI (#87)

    What if work-life balance is a myth, and the real secret is just... life? In this Foojay Podcast we're stepping away from pure code and diving into something equally important: how we live our lives as developers. Because let's be honest, being a great programmer isn't just about mastering Java or the latest framework. It's about managing your career, your health, your family, and finding purpose in all of it. Four incredible guests are all tackling different pieces of this puzzle. First up, Bruno Souza, the Brazilian Java Man, is back to challenge our thinking about work-life balance and share his philosophy on taking control of your career. Then Patricia Lenten talks about the real challenges of hacking parenting while being an engineer, and how we can inspire the next generation of developers. Georgios Diamantopoulos brings the hard data on why sitting is literally killing us and what we can actually do about it. And finally, April Schuppel shares lessons from Apryse's journey through 15 acquisitions in five years—and why people, not AI, are still the most important part of building great products. 00:00 Introduction of topic and guests 01:20 Bruno Souza https://www.linkedin.com/in/brjavaman/Grow your career podcast: https://foojay.io/today/foojay-podcast-72/Bruno's YouTube channel: https://www.youtube.com/@brjavamanWork-life balance doesn't exist, we only have life12:52 Patricia Lenten https://www.linkedin.com/in/patricialenten/Hacking your parentingTechnology is fun18:37 Georgios Diamantopoulos https://www.linkedin.com/in/georgiosd/Staying HealthyThe importance of getting out of your chairhttps://stateofhealth.tech/22:58 April Schuppel https://www.linkedin.com/in/aprilschuppel/Pull, Push, and Merge: Lessons from a Journey of Growth Through AcquisitionsThe people are the most crucial part to build a team, product, and company30:26 Outro

  8. Agents, MCP, and Graph Databases: Java Developers Navigate the AI Revolution (#86)

    Agents, MCP, and Graph Databases: Java Developers Navigate the AI Revolution (#86)

    The AI revolution isn't replacing Java developers. No, it's forcing us to think harder. Welcome to another episode of the Foojay Podcast! Today, we're talking about AI and Java, how it's changing the way we work, what we need to watch out for, and why understanding what's really happening matters more than ever. I recorded interviews at Devoxx and JFall and spoke with people who build and use this technology every day. Marianne Hoornenborg opened my eyes to something important: every time an AI generates a token, there's a massive amount of computation happening behind the scenes. Viktor Gamov and Baruch Sadogursky did something really cool: they tested six different AI coding tools live on stage with the same task. The results were all over the place! But they found that the tools with access to good documentation performed much better. Stephen Chin showed me how graph databases can make AI responses more reliable by providing a solid source of truth rather than relying on vector search. Mario Fusco works on LangChain4J, a leading Java framework for AI. He explained that breaking down large tasks into smaller ones and using specialized agents can help reduce errors—hallucinations, as they're called. Jeroen Benckhuijsen and Martijn Dashorst shared their experiences working with enterprise Java. Even as frameworks are becoming lighter and we're running everything in containers, there are still complex problems that require real developer expertise. Maarten Mulders reminds us that AI is a tool, not a replacement—especially when you're solving problems no one has tackled before. You still need to know what you're doing. And finally, Simon Maple from Tessel discussed moving beyond vibe coding towards a more reliable, production-ready approach, using specifications to guide AI tools. 00:00 Introduction of topics and guests 02:12 Marianne Hoornenborg https://www.linkedin.com/in/mhoornenborg/The Simple Math behind AI The cost of tokens when using LLMs06:54 Viktor Gamov and Baruch Sadogursky https://www.linkedin.com/in/vikgamov/ https://www.linkedin.com/in/jbaruch/ Robocoders, about the many agentic tools that can be used for vibe coding https://context7.com/16:24 Stephen Chin https://www.linkedin.com/in/steveonjava/ Graph versus relational databases Explaining MCP and Agents23:09 Mario Fusco https://www.linkedin.com/in/mario-fusco-3467213/ AI and LangChain4j in Quarkus Coding tools with AI35:43 Jeroen Benckhuijsen https://www.linkedin.com/in/jeroenbenckhuijsen/ Java in business, Evolutions in Java Making use of containers and Kubernetes Learning from the community41:44 Martijn Dashorst https://www.linkedin.com/in/dashorst/ Investigating an OOM-killer in Kubernetes with the help of AI49:37 Maarten Mulders https://www.linkedin.com/in/mthmulders/How AI may impact our jobs How to improve your Maven builds 56:13 Simon Maple https://www.linkedin.com/in/simonmaple/ AI developer tool Tessl Spec-driven vibe coding Secure AI development01:02:12 Conclusion
