Foojay.io | Friends of OpenJDK and Java Programming

On November 9th, we had several interviews with the speakers and guests at the J-Fall conference in the Netherlands. Last week, in episode 33 of the Foojay Podcast, you could hear discussions about the evolution of Java towards the cloud and sustainability. In this part, we will touch on various topics related to the developers' lives.

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.

Once a month we talk about the history of a JUG and the people behind it. Today we travel to the Philippines. A new generation of developers has taken over the organization of the JUG. And in addition, they are also involved in the organization of the Softcon conference. Let's talk about the history and future of the Java community in the Philippines.

The first week of October, the 20th edition of Devoxx took place in Antwerp, Belgium. Over 3000 Java developers, speakers, and enthusiasts gathered to share their knowledge and learn from each other. I got the opportunity to walk around with a microphone and talk to visitors and speakers. Not all of them, as there were just too many people and too many exciting sessions happening simultaneously.

On September 12th, I was invited to speak at the Utrecht JUG together with Hanno Embrechts. That was an ideal moment to grab my camera and microphones to interview the organisers and some of the guests. So this is a bit a special edition of the Foojay Podcast as it’s also available with video! An experiment that brought me great pleasure. I hope you like it too! So … let’s time travel and get back to Utrecht when I got the organizers before the camera just minutes before the first guests arrived…

Artificial Intelligence and ChatGPT are the talk of the town. Every conference has several talks about these technologies, and on Foojay, you can find multiple posts about it. In this podcast, we want to take a look at it from the Java point of view. How can we use AI in Java programs or our job as a developer?

Since 2018, we get a new version of Java every 6 months. And version 21, released this month, will be a long-term support version that can be used for many years. It also brings a lot of new features and improvements in both the language and the runtime. Actually, there are so many that we’ll probably not get all of them discussed in this podcast! Let’s see what our experts find the most important facts we need to know about Java 21.

As developers, we like to automate the boring parts of our job. This automation includes the source control system, build pipelines, and code analysis tools. In recent decades, we have seen evolutions from CVS to Subversion to Git. Is this the endpoint? Did we find the holy grail in version control? Or what evolutions are waiting for us? Let’s find out together with these fantastic guests…

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. And even without an extra library, the JavaFX Components and Canvas provide many animation and gaming possibilities. Let's learn from experts why Java should be on your game-development-language-list!
