Programming
We coax Rhino (an elusive, misunderstood, and ignored member of the Java ecosystem) into a mind meld, giving it access to the JVM's thoughts, experiences, memories, and knowledge; and take it where no rhino has gone before!
I mentioned the idea to use Wordle as an execution profiler while presenting the profiling section of my performance tuning course in Paris last December. The idea was seeded by presentation that Neal Ford did a few years ago in which he used Wordle to expose the vocabulary of a Java application. Instead of vocabulary, I wanted to see if Wordle could be used to visualize an applications dominate behavior.
A new tutorial exercises VisualLangLab using all the examples and techniques in Chapter-3 "A Quick Tour for the Impatient" of the book "The Definitive ANTLR Reference". A new "WildCard" pseudo-token that matches any other defined token has been added to facilitate recovery from grammar errors in the input. Read about the various other improvements that make VisualLangLab even more user-friendly.
This article presents a tutorial for implementing task-focused development using NetBeans IDE with the NBTaskFocus project. Mylyn was the popular project providing task-focused interface for Eclipse and got included in the main Eclipse distribution. These features were in a lot of demand for NetBeans IDE and NBTaskFocus project attempts to provide some of the features in demand. We can now work on our tasks in a better way in NetBeans IDE also using the NBTaskFocus modules.
VisualLangLab parsers support all (present & future) JVM languages
Task Focused Interface has become an accepted concept in the current programming paradigms. Mylyn made a breakthrough to introduce the Task Focused Interface in Eclipse world. Cubeon introduced the Task Focused concepts for NetBeans IDE, with many integrations with third party issue databases like JIRA. I was searching for a Task Focused Interface for NetBeans whch will track my opened files automatically in my current task. I ended creating one such feature in project NBTaskFocus.
It's been a long time, well long in Internet-years, since my last blog on JavaFX. Now I'm approaching JavaFX 2.0 by porting the JavaFX 1.x programs that I had written and blogged about here. These new ports will allow me to evaluate the evolution of the platform. Has the wait been worth it?
Porting from JavaFX 1
For my first port I’ve picked JavaFX Balls. (But this blog is not about...
Here's a tip on how to separate unit tests and integration tests in maven and using profiles to decide which to run (on command line or within NetBeans).
Tools
I think that Maven is a great tool for development. But it can be used for more. For instance, I've just prepared things so that starting from a clean room you can try out my lightweight CMS, NorthernWind, by just invoking a couple of commands. They will install and run NorthernWind, an embedded server and an example site. More information at the NorthernWind blog.
We've just published a new article by Sanjay Dasgupta, administrator of the java.net VisualLanLab project. The article, titled "VisualLangLab - Grammar without Tears," introduces the tool's design, logic, and capabilities...
Education
A preview of the pure Java version of VisualLangLab is now available. The GUI, and other characteristics, are virtually identical to the previous version, but the JAR file is very much smaller as it does not bundle the Scala API jars.
In 1996, a group that I was working with devised a development process which we called Defect Driven Design, otherwise known as D3 (D-Cubed). We were a bit disappointed by not surprised that D3 never really caught on but just recently I saw a glimmer of hope for a revival.
I'll like to let you know the dates of JCertif 2011 the biggest Java Community Event in Africa. About 800+ attendees from many countries.
We will be happy to have you as Speaker on Developer Tools, Java, Open Source, Mobile Apps...or Business solutions.
Still hesitating to join JCertif 2011 ? See the past event : JCertif 2010 and this blog post

Devops and RPM Distribution
Regularly deploying and provisioning RPMs is increasingly becoming a common need. With devops automating every aspect of deployment, including setting up new hosts in virtualized environments, packaging systems such as RPM are getting more and more important. Managed RPMs provide a great level of control over installations and easy upgradability.

Blogging
You know how nowadays everyone loves to tweet at conferences or presentations in middle of the talk? Sometimes you as a presenter might want to return the favor and tweet something in response. If you know upfront that what you are going to present will provoke a response from audience, you can now actually put the tweets in your presenter notes and have Keynote or PowerPoint to tweet on the...

Deployment
Just a quick note to annountce the availability of RainToolkit 1.3.
It can be downloaded at: http://www.logicstyle.com/raintoolkit.html
If you manage Amazon EC2 resources from the command-line, Rain Toolkit can make your life easier by automating a lot of common repetitive tasks.
New features in this release include:
Support for micro instances
Support for EBS instances

This article is an extract from the upcoming book Jenkins: The Definitive Guide, to be published in the coming months with O'Reilly..
One of the more interesting plugins to emerge over the last few months is the Build Pipeline plugin, written by the folks at Centrum Systems. The Build Pipelines plugin takes the idea of build promotion further, and helps you design and monitor deployment...

In JUG-AFRICA we started an Open Source project to manage the BIG ANNUAL EVENTS for our JUGs. The first release will be available in the early second half of January.
The application will provide a lot of services via the REST Web services.
