There is an unwritten tradition that John 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...
My goal: a good-looking and feature-...

There were a few ripples around the Java community given that James Gosling the founding father of Java has left Oracle/Sun.
I'm not that surprised, I'm sure many others are not either. Google must have made inquiries on more than one occasion and Sun had a number of painful years even when I was there, plenty of layoffs that made each release more difficult and that was 5 years ago. ...

In this part we will discuss the basic classes that we will work with them to have file system operations like copying a file, dealing with symbolic links, deleting a file, and so on. I will write a separate entry to introduce classes which are new to Java 7 for dealing with streams and file contents, watching service and directory tree walking. If you want to know what are new features in Java...

I will write a series of blog to discuss what are the new features introduced in NIO.2 (JSR 203). The NIO.2 implementation is a part of OpenJDK project and we can alreay use it by downloading a copy of OpenJDK binary. In the first entry I will just go through what are these new I/O features of Java 7, which help developer iron out better applications easier.
Talking about File systems support...

A few months ago, I had one of those unpleasant format conversion jobs. I had about 1,000 multiple choice questions in RTF format and needed to import them into Moodle.
RTF is, as file formats go, somewhere between the good and the evil. It looks like one should be able to write a parser for it, but that seems like a dreary task. The miracle of open source came through for me, though, in the...

Do you remember the email you got to tell you that your jre had a vulnerability? No? What about the fact that Java 5 is in an end of life phase. Given the time it has taken for Java 7 to appear its has somewhat slowed the normal EOL pace of the Java platforms. You may not know that Java 1.4.2 for business will be supported commercially until April 2018, which is kind of mind-...

Performance: JavaFX Balls
As soon as I've got JavaFX 1.3 and NetBeans 6.9-beta, first thing I did was obviously running benchmarks, and the new update delivers on its promise. Let's first check JavaFX Balls (port of Bubblemark). I've last reported results for 1.2 here; but scores for 1.2 are updated again to account for changes in my test system, remarkably the JDK (now 6u21-ea-b03).

I wanted to describe an interesting problem I recently faced that involved the most excellent JAX-RS specification and its Jersey implementation. The quick overview is that we wanted the output of our JAX-RS resource classes to be client-agnostic, but we also wanted the ability to insert a decorator of sorts in between the objects we were returning and the normal JAX-RS serialization/...

If you wonder whether the style of use with JDBC API has an impact of performance, you might like to read my latest blog entry on Head Crashing Informatics. While the entry mostly is about tuning SQL Anywhere's BLOB handling performance, it contains an interesting aspect: There are three ways to deal with BLOBs in JDBC, and the performance difference is tremendous. While obvious for the JDBC...
