Mon, 13 Jul 2026 00:00:00 +0000

Last week was busy for MelodyMatrix . The website got rebuilt from the ground up, and the app itself got a solid release with a handful of new features.

Closing the Visual Gap Between the Official Lottie Webplayer and Lottie4J

Thu, 02 Jul 2026 00:00:00 +0000

A Lottie library is only as good as its output looks. If an animation renders differently in Lottie4J than it does in the official web player, that’s a bug, even when no exception is thrown and the code looks correct.

Foojay Podcast #99: Testing the Untestable, LLM Security for Java Developers with Tiberius

Mon, 22 Jun 2026 00:00:00 +0000

Unit testing assumes that the same input gives the same output. Large language models break that assumption on purpose, which leaves Java developers wiring LLMs into their applications without a clear way to test for security issues, bias, or prompt injection. Tiberius is an open-source library that tackles exactly this problem, treating non-determinism as part of the design rather than a bug to work around.

Foojay Podcast #97: From Scripting Language to AI Powerhouse with BoxLang

Mon, 01 Jun 2026 00:00:00 +0000

If you write Java day to day, the AI tooling conversation often defaults to Python. BoxLang takes a different route. It runs on the JVM, treats AI as a first-class concern, and lets you mix dynamic templating with the libraries you already trust.

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

Mon, 13 Apr 2026 00:00:00 +0000

A hallway at a Java conference often teaches you more than the talks. People share what broke in production, which JDK version finally pushed them off Java 8, and what tools changed their workflow last month. At VoxxedDays Amsterdam we grabbed fifteen of those conversations on tape with Ko Turk, 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 for Foojay Podcast #93.

Foojay Podcast #91: 25 Years of IntelliJ IDEA: The IDE That Grew Up With Java

Mon, 02 Mar 2026 00:00:00 +0000

IntelliJ IDEA launched in 2000 and grew into the daily workbench for millions of Java developers. Twenty-five years later, the IDE still drives how we refactor, debug, and now pair with AI assistants. To mark the anniversary, we sat down with Marit van Dijk, Anton Arhipov, and Dmitry Jemerov from JetBrains for Foojay Podcast #91.

Foojay Podcast #86: Agents, MCP, and Graph Databases: Java Developers Navigate the AI Revolution

Mon, 15 Dec 2025 00:00:00 +0000

AI tools keep landing on Java teams faster than anyone can evaluate them. The real question is not whether to use them, but how to keep production code reliable when agents start writing parts of it. For this episode we gathered short interviews from Devoxx and JFall, with Marianne Hoornenborg, Viktor Gamov, Baruch Sadogursky, Stephen Chin, Mario Fusco, Jeroen Benckhuijsen, Martijn Dashorst, Maarten Mulders, and Simon Maple in Foojay Podcast #86.

Foojay Podcast #82: OpenJDK Projects (Leyden, Babylon, Panama) and TornadoVM

Mon, 17 Nov 2025 00:00:00 +0000

Java keeps picking up speed, and a lot of that momentum comes from a handful of OpenJDK projects most developers have only read about in release notes. Leyden trims startup time, Panama opens the door to vectors and native code, and Babylon pairs with TornadoVM to push Java workloads onto the GPU. In this episode we sit down with Moritz Halbritter, John Cecerralli, Balkrishna Rawool, Christos Kotselidis, and Michalis Papadimitriou to map out what each project does and how they fit together. This is Foojay Podcast #82.

Foojay Podcast #80: AI4Devs Interviews – Part 2

Mon, 20 Oct 2025 00:00:00 +0000

The first AI4Devs conference in Amsterdam brought together developers, data scientists, conference organizers, and even a student to share how AI shifts their daily work. We grabbed a microphone between sessions and asked each of them what stood out. I host this second batch of short interviews as Foojay Podcast #80, with Eileen Kapel, Jonathan Ellis and Ryan Svihla from Brokk, David Parry from Qodo, Alessandro Stefouli-Vozza, Sushant Shekhar, Arno Koehler, Joost Kaan, Coen de Waal, Samantha Burattini, Luis San Martin, Nahir Vila, and conference organizer Jonathan Vila.

Foojay Podcast #79: AI4Devs Interviews – Part 1

Mon, 06 Oct 2025 00:00:00 +0000

AI changes how we write and ship code every week, and the questions pile up faster than the answers. At the first AI4Devs conference in Amsterdam on September 19th, 2025, I grabbed my camera and microphone to talk with speakers and attendees about what actually works. In this first part we hear from Christian Tzolov and Josh Long, Brian Vermeer, Camille Nigon and Maarten Vandeperre, Luca Berton, Soham Dasgupta, Mary Grygleski, and Anton Arhipov in Foojay Podcast #79.

Foojay Podcast #76: DevBcn Report, Part 1 – Learn from the Community

Mon, 21 Jul 2025 00:00:00 +0000

What does the Java community sound like when you put a microphone in front of it at a Barcelona conference? In early July, DevBcn brought together speakers and visitors from across the ecosystem, and Geertjan Wielenga carried a recorder through the venue to capture their answers. We hear about favorite parts of Java, the impact of AI on daily coding, and the topics that pull developers toward new tools and ideas. This is part one of the DevBcn Report, hosted by Geertjan Wielenga with organizers Nacho Cougil and Jonathan Vila, plus more than twenty community members, in Foojay Podcast #76.

Foojay Podcast #74: JCON Report, Part 3 - AI, ChatGPT, LLM, ML, RAG, MCP, GenAI, and more

Mon, 30 Jun 2025 00:00:00 +0000

AI talk often stays abstract, but Java developers want to know which frameworks, protocols, and patterns actually hold up in real projects. At JCON in May, we cornered speakers between sessions to ask exactly that. In this third and final JCON recap, Pasha Finkelshteyn, Simone de Gijt, Steve Poole, Sandra Ahlgrimm, Mary Grygleski, Jonathan Vila, Simon Martinelli, and Emily Jiang join me for Foojay Podcast #74, Season 4.

Foojay Podcast #69: All Things Java at VoxxedDays Amsterdam

Mon, 14 Apr 2025 00:00:00 +0000

A conference floor at VoxxedDays Amsterdam holds dozens of small conversations that rarely make it to a recording. This episode breaks that pattern by stitching many of those hallway chats into one show. Geertjan Wielenga asked every guest the same two questions about what they care about in Java right now and what they want to share with the community. The guest list includes Ko Turk, Stephan Janssen, Lutske de Leeuw, Johannes Bechberger, Christian Tzolov, Tom Cools, Eric-Wubbo Lameijer, Abraham van de Vyver, Soham Dasgupta, Josh Long, Susanne Pieterse, Brian Vermeer, Anton de Ruiter, Rafael De Lio, Jonathan Stronkhorst, Jos Roseboom, Soroosh Khodami, Artem Makarov, Kaya Weers, Eddy Vos, Paco van Beckhoven, Hanno Embregts, Martijn van Iersel, Charl Fasching, and Joris Kuipers, making this the first Foojay Podcast ever with more than 20 guests.

Foojay Podcast #62: Better Coding with AI: Friend or Enemy?

Mon, 02 Dec 2024 00:00:00 +0000

AI tools promise faster code and smarter suggestions, but how far can we trust them inside a real Java project? In this Foojay Podcast #62, we sat down with Grace Jansen, Sean Li, John Sterken, David Vlijmincx, Urs Peter, and Joost Kaan to compare notes on what works, what breaks, and where developers still need to stay in the driver’s seat.

Foojay Podcast #56: Vectors in Java Code, Databases, and LLMs

Mon, 08 Jul 2024 00:00:00 +0000

Vectors sit at the heart of modern AI, yet most Java developers rarely touch them directly. This episode digs into what a vector really is, how databases store them, and why large language models depend on them. We also look at how the Java Vector API and the Foreign Function & Memory API change what the JVM can do with this kind of workload. I host this conversation with Jonathan Ellis and Alexander Chatzizacharias in Foojay Podcast #56, the closing episode of season 3.

Foojay Podcast #49: JCON Report, Part 1 - JUGs, Communities, Open Source, Generative AI, LangChain4j, Machine Learning

Tue, 21 May 2024 00:00:00 +0000

Walking the floor at a Java conference is the fastest way to learn what the community actually cares about right now. We packed a microphone and took the Foojay Podcast on the road to JCON in Cologne, capturing short conversations between sessions. We talked with Geertjan Wielenga, Markus Kett, Richard Fichtner, Jonathan Vila, Soham Dasgupta, Mary Grygleski, Mohammed Aboullaite, Simon de Groot, and Richelle Bussenius for episode #49.

Foojay Podcast #47: Artificial Intelligence and Machine Learning with Java

Mon, 15 Apr 2024 00:00:00 +0000

ChatGPT changed the way many of us think about software, but the Java ecosystem already has the tools to join in. Frameworks like LangChain4j make it possible to wire large language models into real applications without leaving the JVM. In this Foojay Podcast #47, we sat down with Lize Raes and Lutske de Leeuw to talk through what AI and machine learning look like from a Java developer’s chair.

Foojay Podcast #43: Modern Java Testing

Mon, 26 Feb 2024 00:00:00 +0000

Every Java developer wants to ship code that works, but tests often feel like a tax instead of a tool. The testing pyramid we all learned about does not always match what we hit in real projects. We sat down with Oleg Šelajev, Roni Dover, and Jonas Geiregat in Foojay Podcast #43 to dig into how modern Java teams actually approach testing today.

Foojay Podcast #32: Philippines JUG

Mon, 06 Nov 2023 00:00:00 +0000

Java communities look different in every country, and the Philippines shows that well. A younger crew now leads the local JUG and shapes the Softcon conference at the same time. In this conversation we look at how they keep the group active, how COVID changed their meetups, and where AI fits in their plans. I sat down with Tristan Mahinay, Calen Legaspi, Jansen Marson Ang, and Kerby Martino for Foojay Podcast #32.

Foojay Podcast #29: How will AI and ML Influence the Role of Developers?

Mon, 25 Sep 2023 00:00:00 +0000

AI and ML keep showing up in pull requests, IDE suggestions, and debugging sessions, and Java developers feel the shift first-hand. We sat down to ask what these tools actually change in the day-to-day work, and where they still fall short. In this episode I host Zoran Sevarac, Frank Greco, and Roni Dover for Foojay Podcast #29.
