We serve you a podcast about the new Java version every six months. Our regular guest, Simon Ritter, Deputy CTO of Azul, is known on social media as "speakjava." He is part of the OpenJDK vulnerability group, JCP executive committee, and expert group for the Java SE specification request so that he can share a lot of inside information with us. In this episode, we are joined by Hanno Embregts, a Java Developer by day and musician by night. He publishes a post on Foojay with all the details of every new Java release and prepared a long description of all the new features included in Java 24. Let's see what this new release brings us...

Writing a book. Does it make you rich and famous? (#67) 1:15:28

לפני 22 weeks1:15:28

1:15:28

Let me share a personal story. I started experimenting with Java on a Raspberry Pi about five years ago and blogged a few articles about it. But the more I experimented, the more I wrote down, and eventually, I had written a book… I worked on it for six months in a row, every evening and a lot of weekends. But the moment I received the box with my author copies was an incredible feeling. Holding a paper book with your name is a special moment. Fast forward to now. The 1000 paper copies are sold out. I have the last 10 copies in case you still want one ;-) But as I self-published the ebook, it's still for sale on Leanpub, and I keep updating it. That's one of the first significant differences between publishing a paper book and an ebook…. As an author, I got about 2 euros per paper book from the publisher, and LeanPub pays 80% royalties. Don't forget that I have to pay taxes on what I earn. So, if you do the math, you'll understand that the book didn't make me rich. But yes, it helped me in my career and was one of the reasons I became a Java Champion. So, we can argue about the "becoming famous". But that's only my story. I invited several guests to share their knowledge about book writing: Marián Varga is finishing a book and tells about publishing a book with a publisher. Wim Deblauwe wrote a few books and has much experience with self-publishing. Len Epp is the co-founder of Leanpub, so he can tell us a lot about ebooks. And we start with Trisha Gee, who wrote a lot of books!

In this Foojay podcast, we dive into a few articles that were published recently and focus on code. Igor Kulakov of JetBrains gives us his insights into the tool he created to find duplicate content in documentation. Rijo Sam explains how you can generate real random values and how he created a train departure display. Maxillian Arruda explains in a very detailed post the different ways to construct a complex Java object. And we start with Wim De Troye about the code changes he had to do in a project that got upgraded from Spring Boot 2 to 3.

How do we keep our Java applications up to date and secure (#63) 43:12

לפני 32 weeks43:12

43:12

Last month, I published a Foojay blog post about the risks in systems that are stuck on old or outdated Java versions and got a lot of feedback from developers. Most of them want to move on but get stuck on management decisions, outdated production environments, or one of the many other reasons that keep systems stuck on old Java versions and dependencies... Do you want to bring your system from Java 8 to 23? Did you know that Java 17 already got 13 security releases? And that you can use tools like OpenRewrite to help you update your code?

Better Coding with AI: Friend or Enemy? (#62) 43:46

AI, LLMs, ChatGPT—these are just a few of the buzzwords of the massive revolution unfolding right now. These tools are reshaping how we work, but they come with a catch: while they help us work faster and smarter, we need to be careful about placing too much trust in them. I’ve spoken with several guests at the JFall conference in the Netherlands actively working with these tools to learn more about them.
