Deep dive into bits, bytes, shorts, ints, longs, signed, and unsigned with Java
On the Pi4J discussion list, someone recently asked what the best and easiest way is in Java to convert a byte value. In Java, there is no distinction between signed and unsigned bytes, which can be confusing. My book “Getting Started with Java on the Raspberry Pi” contains an explanation about this, and I am happy to share it in this post with some more info and code examples…
JavaFX In Action #6 with Ramiro Domínguez Ayub about the Televic Generic Update Tool (TGUT)
In the next “JFX In Action”, I’m returning to Televic, one of my former employers, to talk to Ramiro Domínguez Ayub. He explains how they create a tool with JavaFX that is used both internally and by their customers to update a lot of different types of devices on a train, tram, and/or metro.
JavaFX with Kotlin versus Java
Recently I have been experimenting with the combination of JavaFX and Kotlin. As Kotlin also runs on the Java Virtual Machine (JVM) and is a very close sister of Java, the switch is straightforward. I’m not making full use of what Kotlin can offer (non-blocking coroutines for example) as this is still a learning path for me… But I want to show you in this tutorial the difference in code style.
JavaFX In Action #5 with Maciej Gorywoda about FxCalculator, an Android app built with Scala and JavaFX
In the next video in this “JFX In Action” series, I talked with Maciej Gorywoda about FxCalculator, an Android app created with Scala and JavaFX you can find in Google Play.
How we almost missed a plane in Kazakhstan, but OpenJDK could have saved us...
In August, our family vacation brought us to Kazakhstan. An important trip, as it is the birth country of our (now) 14y son. It was over 13 years that we had been there and we planned to go back earlier, but some stupid virus messed up everyones life a few years ago… So finally, early this year, we decided to start organizing our trip. Or to be fully honest, we asked Ardjan of “Kazachstan Reizen” to do that for you. And we had an amazing trip, visited different cities and national parks, and had a fantastic time.
First experiments with Raspberry Pi Compute Module 4
I’m one of those people with boxes full of devices, waiting to be used in experiments… And from time to time, I dive into those boxes to fill in the gaps in between other tasks. So these are the results of my first Raspberry Pi Compute Module experiments!

JavaFX Nodes versus Canvas
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.
