This is part 4 of the JCON interviews. In this episode, we have 5 new guests for you. We start with garbage collectors and Intelligence Cloud, a tool created by Azul to find out which of your code is actually used in production and which dependencies are known to have vulnerabilities. My colleague Gerrit Grunwald was at JCON to give a talk about these subjects. With Balkrishna Rawool we dove into Virtual Threads, a very interesting topic as concurrency and threads can be challenging... Piotr Przybyl came to JCON to give a talk about Test Containers and how to test your application in an environment that is similar to your production environment. Another important topic related to testing is Flaky Tests. How do you handle tests that only fail from time to time and make your whole test report unreliable? François Martin had a talk about this subject, and he came to the conference together with Annelore Egger, who was one of the many volunteers.

This is part 3 of the JCON interviews. In this episode, Frank meets Otavio Santana, who recently wrote the book "Mastering the Java Virtual Machine." At JCON, he talked about the persistence layer and how you can evolve your career. You'll also learn more about Jakarta EE, GlassFish, and a PET project with messaging via Telegram.

This is part 2 of the interviews we recorded at the JCON conference earlier this month in Germany. In this episode you get two main topics: Maven and Code Quality. In the first part, you'll hear Karl Heinz Marbaise and Steve Pool about the Maven project, the repository, Sonaytype and the security impact of dependencies. But next to security, we as developers are also responsible for the creation of readable and maintainable code. Miro Wengner, Marit van Dijk, and Hinse ter Schuur dive into this topic.00:28 Karl Heinz Marbaise: Apache Maven version 4, Sonatype, Maven Repositoryhttps://www.linkedin.com/in/khmarbaise/ 09:59 Steve Poole: Sonatype, The many languages running on the JVM, The possible impact on a company of getting hacked, Talks about software supply chain security, Maven, SBOMs,… https://www.linkedin.com/in/noregressions/27:44 Miro Wegner: Talks about Disciplined Engineering https://www.linkedin.com/in/mwengner/ 34:52 Marit van Dijk: Talks about IntelliJIDEA, reading code, and AI Assistant  https://www.linkedin.com/in/maritvandijk/ 43:50 Hinse ter Schuur: Being a sustainable developer, Talks about code reviews, merge requests, and branching  https://www.linkedin.com/in/hinseterschuur/

On Tuesday, May 14th, the Foojay Podcast went live at the JCON conference in Cologne, Germany, to talk with speakers and visitors about all things Java. We had so many amazing talks that we will combine them into several podcast episodes in the next weeks.

Once a month, in the Foojay Podcast, we discuss the history of a Java User Group and the people behind it. In this episode, we are in Oberpfalz, Germany, for a particular reason. The organizers of the local JUG are the same people responsible for the JCON conference in Cologne in a few weeks. Let's learn more about the Java community in Germany.

About one and a half years ago, ChatGPT was launched. The way we search for information and develop software has changed a lot since then as the use of Artificial Intelligence suddenly became a lot easier. What can we expect in the near future, and how can we program AI ourselves with Java? Let's find out...
