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

8 weeks ago1:15:28

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!

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

18 weeks ago43:12

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Last month, I published a Foojay blog post about the risks in systems that are stuck on old or outdated Java versions and got a lot of feedback from developers. Most of them want to move on but get stuck on management decisions, outdated production environments, or one of the many other reasons that keep systems stuck on old Java versions and dependencies...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

20 weeks ago43:46

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.

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.

A few months ago, we asked the J-Fall organization team if a Foojay Broadcast Room would be a good idea. And they said yes, so suddenly we found ourselves in the middle of the entrance of the Pathé cinema in Ede in the Netherlands, with a camera and microphones. During the day, we had a lot of exciting talks. There are way too many to fit in one podcast, so in the following weeks, you will get different episodes handling a lot of topics. This is part 1, and we talk about J-Fall of course. But also about the evolutions in Java and how it’s becoming the best cloud environment while keeping systems sustainable, and reducing the ecological, financial, and security impact of applications. 00:00 Introduction 00:59 Brian Vermeer: About J-Fall https://twitter.com/BrianVerm https://www.linkedin.com/in/brianvermeer/ https://mastodon.social/@brianverm https://jfall.nl https://nljug.org/ https://foojay.io/today/author/bmvermeer/ 03:50 Pratik Patel: Evolutions of Java https://twitter.com/prpatel https://www.linkedin.com/in/prpatel/ https://mastodon.social/@prpatel State of Java Survey and Report 2023: https://www.azul.com/report/2023-state-of-java/ OpenJDK Migration for Dummies: https://www.azul.com/openjdk-migration-for-dummies/ 13:33 Grace Jansen: Cloud Java https://twitter.com/gracejansen27 https://www.linkedin.com/in/grace-jansen/ 20:22 Mark van der Walle: FinOps, EcoOps https://twitter.com/mvdwalle https://www.linkedin.com/in/mvanderwalle/ 25:56 Ko Turk: Sustainability https://twitter.com/KoTurk77 https://www.linkedin.com/in/ko-turk-b271b929/ 30:37 Ionut Balosin: Sustainability and Green Engineering https://twitter.com/ionutbalosin https://www.linkedin.com/in/ionutbalosin/ 35:28 Deepu Sasidharan: Passkeys and Security https://twitter.com/deepu105 https://www.linkedin.com/in/deepu05/ https://mastodon.social/@deepu105 https://foojay.io/today/author/deepu-sasidharan/ 42:18 Outro Host Frank Delporte https://foojay.social/@frankdelporte https://www.linkedin.com/in/frankdelporte/ https://foojay.io/today/author/frankdelporte/ Music Barbershop John Hermine Deurloo Synapse by Shane Ivers - https://www.silvermansound.com…

Game Development with Java, JavaFX, and FXGL (#25) 56:10

Java and JavaFX are probably not the first options you consider if you want to create a game application. But the FXGL library allows you to do precisely that: create games that run on all platforms with the same codebase as we are used to with Java.

How do you get the maximum performance out of your Java application? And how to use profiling to find the bottlenecks? Let's learn it in this podcast! Java profiling is a crucial technique for measuring and improving the performance of applications. It helps identify bottlenecks, memory leaks, and other application performance issues. There are various challenges with using Java profiling, and the need for profiling depends on the complexity of the application and the performance requirements. Let us learn more about the challenges, different profiling approaches, and when to use Java profiling to reach the best performance with our Java code.

Why So Many JDKs? (#4) 53:55

4 years ago53:55

53:55

In this podcast, we explore the topic of why there are so many JDKs, how are they the same, and how they are different. We balance the Java perspective with a special guest from the Rust foundation to learn how a peer ecosystem works. Quick summary—the role of Java as a central system runtime lead to multiple implementations and the companies that make different distributions offer support and sponsor different work. For example Azul and Microsoft worked on Apple M1, and Bellsoft and Microsoft worked on Alpine Musl. All JREs are compatible through the TCK and vendors work together on security patches for the entire ecosystem. Guests: Simon Ritter, Deputy CTO of Azul Systems, making the Azul Platform, including the Azul Zulu builds of OpenJDK. Dmitry Chuyko, Senior Performance Engineer of Bellsoft, making the Liberica builds of OpenJDK. Bruno Borges, Product Manager Microsoft, making the Microsoft builds of OpenJDK and Temurin, Adoptium's builds of OpenJDK. Ashley Williams, founder and open-source strategist for the Rust Foundation. Erik Costlow, Developer Relations for Contrast Security, securing Java and non-Java applications. Foojay Articles: Fantastic JVMs and Where to Find Them…
