GUI
In my last blog I’ve introduced JavaFX 2.0 beta, describing an initial port of JavaFX Balls, also in beta stage at that time. Now I finally finish JavaFX Balls 3.
Look ma, no design!
I don’t pretend to be a designer, and the consequence is that when I make a mashup of animation, video and web, that’s the result. Get the source code here.
I’ve added new layers of content...
The biggest announcement - and the biggest surprise for many - of JavaOne 2010 was certainly Oracle's new plans for JavaFX 2.0... or, should we say, Swing 2.0?
I've finished the development of my Game of Life, with a couple final fixes and new features... including a solution to the bad performance reported before. Once again the work has uncovered some surprises; read on.
JavaFX 1.3, codename SoMa, was released at long last on April 22 - after some delays (originally due November 2009) and feature cuts (the new Prism toolkit has shipped but in EA status). In this blog I will explore the performance improvements of JavaFX's graphics stack, including Prism. Just take a cup of coffee to ride this blog - it's long, seven miles.

JavaFX 2.0 is not multiplatform! It can't do subpixel antialiasing!! … these were among the reactions to the first beta releases, that I'm not sure to understand as trolling or simple laziness. These mysteries are usually solved with a simple look at JavaFX's public JIRA issue tracking system. The current implementation is still a beta, not even a feature-complete beta, so there are many...
If you want to work for DropBox, they have an interesting programming test which solution must be submitted together with the CV. I’m not considering a position at DropBox, but their test was very fun to ignore: an interesting challenge in algorithms, and another opportunity to exercise JavaFX as any geometric problem surely deserves some GUI.
Now that JDK 6u21, JavaFX 1.3.1 and NetBeans 6.9.1 are all finally released, I'm back to checking the latest news and improvements in JavaFX. The official Release Notes points to the deployment improvements as the single new end-user feature, so I've checked the latest improvements in this area.
I was doing some JavaFX hacking, and I had to create a sequence initially full of zeros. How can you do that? There's apparently only one way...
There is an unwritten tradition that Hector Conway's Game of Life must be implemented in every programming language and every GUI toolkit. Well, OK I just invented this tradition, but it's a smart introduction and Life is one of the easiest games / cool animations you can program. But it's not too simple that we can't learn a few important things about JavaFX...
In my last attempt to stress the JavaFX platform, I ported the Strange Attractor demo/benchmark. Different from JavaFX Balls, this is not scenegraph-driven animation, but old-school "pixel by pixel" drawing… still, makes for another batch of interesting findings, including a few issues in the JavaFX Script language and its compiler, and other topics like fractal maths, BigDecimal...
Sun just released the first maintenance update for JavaFX 1.2. This release brings mostly a batch of important javafxc fixes, that I dissect in this blog...
Java programmers are used to the fact that compilation of Java source code is a relatively straightforward process, because the Java language has a simple mapping to the Java bytecode. So javac is a trivial compiler, at least in the code...

Mark Reinhold announced today that the JDK 7 / JavaSE 7 project has slipped once again: mid-2011 without Jigsaws and Lambdas, late 2012 for JavaSE 8 with those. The delay (or some other bad news like dropping features) was already expected by anyone who tracks the project. But really, how big and bad is this delay?
Performance
Java SE 5.0 Update 8 is available, and it solves important performance bugs. I analyze (in gory detail) one of these...
