Sheetmusic4J 0.0.3: ABC Notation, Guitar Pro, Engraving Improvements

Thu, 30 Jul 2026 00:00:00 +0000

Last week I introduced Sheetmusic4J , a Java(FX) library to render and interact with sheet music. That first 0.0.1 release was really a question more than a product: is there any interest in a native Java(FX) sheet music library before I invest more time in it? So I shared it on social media and waited to see what would come back.

MelodyMatrix 1.2.0 and 1.2.1: Learn Section Groundwork, Playback Improvements, and a Startup Fix

Wed, 29 Jul 2026 00:00:00 +0000

Two MelodyMatrix releases went out last week, one right after the other. 1.2.0 brings the first steps toward a Learn section, some playback improvements, and initial MusicXML support. 1.2.1 followed a day later to fix a startup issue that 1.2.0 itself introduced.

Introducing Sheetmusic4J, a Java(FX) Library to Render and Interact with Sheet Music

Fri, 24 Jul 2026 00:00:00 +0000

I’m building MelodyMatrix with my son, an application to look at and play along with music. The app already shows a song in different views: falling blocks, chords, guitar views, and many more. Now we want a Learn section, a view that helps someone practice piano by following the actual sheet music while it plays.

First Test of Java on Banana Pi (ARM and RISC-V), Plus a Blinking LED with Pi4J

Thu, 16 Jul 2026 00:00:00 +0000

As part of my 2026 learning goals around Java on RISC-V (see this post about x86 versus ARM versus RISC-V ), I’ve asked various suppliers to send me evaluation boards. I already published these:

A New Website for MelodyMatrix, and What's New in Release 1.1.0

Mon, 13 Jul 2026 00:00:00 +0000

Last week was busy for MelodyMatrix . The website got rebuilt from the ground up, and the app itself got a solid release with a handful of new features.

Foojay Podcast #100: Java Podcasters on Why They Started, What Broke, and What They Learned

Mon, 13 Jul 2026 00:00:00 +0000

Foojay Podcast hits episode 100. No plan, no roadmap, it just happened. To mark the occasion, I turned the microphone around and invited other podcasters from the Java community to answer the same three questions I usually ask my guests: why did you start, what broke, and what did you learn?

My Book 'Java Programming for Raspberry Pi' is Now Available as Softcover and Hardcover on Amazon

Fri, 10 Jul 2026 00:00:00 +0000

“Java Programming for Raspberry Pi: A Hands-On Guide to Electronics and IoT Projects” is now available as a softcover and hardcover paper book through Amazon, on top of the Kindle ebook and the pay-as-you-wish version on Leanpub . If you prefer holding a physical book while you’re wiring up LEDs and sensors on your Raspberry Pi, that’s now possible again.

Closing the Visual Gap Between the Official Lottie Webplayer and Lottie4J

Thu, 02 Jul 2026 00:00:00 +0000

A Lottie library is only as good as its output looks. If an animation renders differently in Lottie4J than it does in the official web player, that’s a bug, even when no exception is thrown and the code looks correct.

From breadboard chaos to a real PCB: designing the Pi4J smoke test board

Thu, 25 Jun 2026 00:00:00 +0000

Testing a Java I/O library properly means testing it on real hardware. No mocks, no stubs, just actual pins doing actual things. For Pi4J, that means running the smoke test: a setup with two BMP/BME280 sensors, some GPIO-to-GPIO jumper connections, and a bunch of patience while you untangle the wires for the third time this week.

JavaFX In Action #27 with David Gutierrez about JMathAnim to Create Mathematical Animations

Thu, 25 Jun 2026 00:00:00 +0000

The JFX Central Links Of The Week is a great source to discover what is happening in the JavaFX world. One of the projects that caught my eye is JMathAnim, a tool to create mathematical animations built on top of JavaFX. In this interview, David Gutierrez, a mathematician from Spain, walks us through what the project can do and how it came to life.

Foojay Podcast #99: Testing the Untestable, LLM Security for Java Developers with Tiberius

Mon, 22 Jun 2026 00:00:00 +0000

Unit testing assumes that the same input gives the same output. Large language models break that assumption on purpose, which leaves Java developers wiring LLMs into their applications without a clear way to test for security issues, bias, or prompt injection. Tiberius is an open-source library that tackles exactly this problem, treating non-determinism as part of the design rather than a bug to work around.

A Fresh Design for webtechie.be

Wed, 17 Jun 2026 00:00:00 +0000

This website grew over many years into more than 260 posts, 220 videos, 100 podcasts, and 60 presentations. The old design buried most of that under a layout that no longer matched the way I write today. So I rebuilt it from the ground up, and the result puts the content first.

Foojay Podcast #98: The End of JNI Pain, How WebAssembly Is Quietly Replacing Native Libraries in Java

Mon, 15 Jun 2026 00:00:00 +0000

JNI has been the standard answer for calling native code from Java for almost three decades. It also brings most of the headaches anyone who has wrestled with it remembers: brittle bindings, crashes that take the JVM down with them, painful cross-platform builds. WebAssembly quietly changes the shape of that problem. You get a sandboxed runtime, a portable binary format, and a far gentler integration path into the JVM.

Lottie4J Meets LottieFiles: A Conversation with Naail Abdul Rahman

Thu, 04 Jun 2026 00:00:00 +0000

Lottie animations run on Android, iOS, and the web. Getting them working on the JVM is a different story. Lottie4J started as a question: can JavaFX render them without a WebView? That question turned into a library with a first release in March 2026! Since then, I received the first pull requests, recently added headless unit testing with JavaFX 26, and now this: a video conversation with Naail from the LottieFiles team.

Foojay Podcast #97: From Scripting Language to AI Powerhouse with BoxLang

Mon, 01 Jun 2026 00:00:00 +0000

If you write Java day to day, the AI tooling conversation often defaults to Python. BoxLang takes a different route. It runs on the JVM, treats AI as a first-class concern, and lets you mix dynamic templating with the libraries you already trust.

Foojay Podcast #96: Local AWS Development Without LocalStack: Meet Floci, the GraalVM-Powered Alternative

Mon, 25 May 2026 00:00:00 +0000

Running AWS services on your laptop usually means waiting for a heavy emulator to boot, watching memory fill up, and hoping the API behavior matches the real cloud. Floci takes a different path. It spins up 35 AWS services in about 25 milliseconds with 13 megabytes of memory, using a single Docker command. In this episode we sat down with Hector Ventura, the creator of Floci, for Foojay Podcast #96.

Is Your Java App Actually Secure, Or Does It Just Look That Way?

Mon, 11 May 2026 00:00:00 +0000

Your Java app passes the build, the tests are green, and the dashboard looks fine. But are the libraries underneath still maintained, or are they quietly collecting vulnerabilities? In this episode we dig into “zombie dependencies”, the CVE process, and the small habits that make a real difference. I host Steve Poole and David Welch from HeroDevs for Foojay Podcast #95.
