Last week I was working on a blog post about Azul Zulu with JavaFX support for ARM systems, like the Raspberry Pi. As you can see in this video, I found out my little test application with a lot of “bouncing balls” started losing performance on the Raspberry Pi with more than 1000 of those balls.

Lessons Learned from JavaOnRaspberryPi, the Potential of Bits and Bytes, Cost and Eco-Efficiency I started experimenting with Java on the Raspberry Pi a few years ago because I wanted to learn if I could control electronic components with my favorite programming language.
At the Fosdem conference in Brussels on February 3rd, I gave a presentation about using an existing documentation set as the data for a ChatGPT-like application, created with JavaFX and LangChain4J. The video and links of that presentation are available here, and this post is a more detailed explanation of that application.

Experimenting with AI and LLM to make docs searchable through a chat application ChatGPT is considered to bring the end to search engines. But it’s also a pretty good liar, just making stories up.

What I Learned About OpenJDK As a Docs Writer As a teenager, a Commodore 64 and DIY solder kits ignited my passion for computers and electronics. But for some obscure reason, I chose an unexpected path by attending film school.
On July 15th of 2023, I published a post here about my initial experiments with CRaC on the Raspberry Pi. At that time, I found out that both the Linux kernel in Raspberry Pi OS and the Zulu Build of OpenJDK still needed some changes to work on the Raspberry Pi.

Unlocking the Potential of Bits and Bytes: Reducing Data Footprint for Cost and Eco-Efficiency In the age of unlimited storage space, we forget to consider the financial and ecological costs. Transmitting and storing data in XML, JSON, or (if you want to hurt people) YAML makes data human-readable, which is great for debugging and testing but is a very inefficient, heavy, and expensive way of handling data.
With the April release of the Zulu Build of OpenJDK, Azul announced the integration of CRaC in its version 17 of Java for Linux. Coordinated Restore at Checkpoint (CRaC) is a feature introduced in OpenJDK to improve Java’s application startup and warmup times to milliseconds from seconds or even minutes, by allowing a running application to pause, snapshot its state, and restart later, even on a different machine.
Writing has always been my passion, and even in my previous jobs as a developer, I stood out as the one who enjoyed creating and maintaining documentation. But June 9th, 2023, marked my first birthday as a full-time technical writer at Azul. Yes, it’s already a year ago that I changed from being a developer-who-also-writes to a writer-who-also-develops.
On Foojay.io, Bazlur Rahman is publishing a series of interviews with various people from the OpenJDK community. I had the honor to be included in this series, and this is a repost. Welcome to our exclusive interview with Frank Delporte, a Senior Technical Writer at Azul, Java Champion, and a passionate advocate for all things related to Java and Java on Raspberry Pi.
For this post I did some experiments with Java 15, reusing the Ubuntu 64bit SD card which was also used for the earlier post “Comparing a REST H2 Spring versus Quarkus application on Raspberry Pi”. That version of Ubuntu comes with OpenJDK 11 pre-installed. $ java -version openjdk version "11.0.8" 2020-07-14 OpenJDK Runtime Environment (build 11.
In a previous post “Installing Java and JavaFX on the Raspberry Pi”, you can read how to install BellSoft LibericaJDK to be able to run JavaFX applications with a graphical user interface on a Raspberry Pi with ARMv7 or ARMv8 processor. But this won’t work for some (older) versions of the Raspberry Pi as these use an ARMv6 processor which is not compatible with the default OpenJDK 11 which is part of Raspberry Pi OS.
