Hi, Spring fans! In this episode, Josh sits down with longtime friend and JetBrains developer Anton Arkhipov for a fascinating look at how AI is reshaping the way software gets built. From the halls of Devoxx to the future of IntelliJ IDEA, the conversation explores how AI has moved from being a novelty to becoming a core part of modern development workflows. Anton shares how JetBrains is experimenting with a new “agent-first” way of working, where chat becomes the central interface and AI agents can help plan features, generate code, run tests, and even debug problems. They dive into…

This time around, I'll be talking about Spring Security and Spring Boot 4.x. We've got a lot to get into this week so let's do! Spring AI lead Christian Tsolov has a wonderful post on using Spring AI to build modular RAG solutions with TypeSafe…

Hi, Spring fans! What if the JVM could feel as frictionless as the modern dev tools people rave about on other platforms? In this wide-ranging, high-energy conversation, you’ll hear two longtime friends (Andres Almiray is a fellow Java champion and a legend) geek out over the future of desktop Java, the pain of Electron, the elegance of JavaFX, and the tools making it all easier to ship.
