This example illustrated the differences in rendering polygon using AS3 and C#. You may also reuse the Class as your drawing Library. It included both Flash and Silverlight versions with complete source codes.

A new project from the JavaBuilders.org family. Focuses on bytecode instrumentation of existing Java classes to enable databinding with no more than 1-2 lines of code. Uses the Javassist bytecode library and the standard Beans Binding library under the hood.

A stunning effect with a laser orbiting around the mouse! In this example, it demonstrated the difference in dispatching Event between AS3 and C#. It included both Flash and Silverlight versions with complete source codes.

Here is another 3D application without using any 3D Library. You may navigate the application via a mouse click or mouse wheel. A spring effect is also applied. Let’s see how brilliant it is! It included both Flash and Silverlight version with complete source codes.

think Groovy - as a language - has potential to ease the development effort in a typical JEE development environment. There have been a ton of web pages about why Groovy is cool and I’ll leave that as an exercise for the reader to follow up on. Before we get to the meat of this post I just want to be very clear that I’m a Groovy fan.

Our busy community of plugin developers have been at it again and now there is a brand new plugin for Grails that adds support for the Terracotta data grid.

A commenter reminds me on Groovy (It was mentioned as part of Grails). His comment makes me curious on what’s the latest on Groovy and how it is stacking up to Jython.

A while ago I thought of looking at trying to integrate db4o, an open-source object database, into Grails. I hit a problem, which is that grails is built around the principle of transparent persistence: changes to instances of persistence classes don‘t have to be kept track of by the developer, and any changes are written to the data store when a “commit“ is performed. Db4o did not have this capability, so I put the project aside.

When it comes to Image Manipulation, Flash and Silverlight has much more advantages over Javascript and DHTML. In this example, when you click on the image, it will produce an amazing sponge effect. What’s more? Just to use your imagination! It included both Flash and Silverlight version with complete source codes.

The new edition of fckeditor plugin for Grails seems to work properly with the most recent 1.0 releases. Also at first glance seems more configurable.

This is an advanced image rotator effect. If you always use fade in/out effect only, you probably have to look into this one. It included both Flash and Silverlight version with complete source codes. This is just one of the rotator effects in my hand, I will continue to post more in the coming days.

This is a a Simple Fish Eye Menu (or Dock Menu). The logic is simple and you may further customize it as your own menu. It included both Flash and Silverlight version with complete source codes.

Recognising those people who contribute heavily to our community through mailing lists, plugins, blogs, source code and other coolness.

The title says it all, MetaBuilder is a builder that let's you create other builders. Dave Masser-Fryehas released this project under the Apache Software License 2.0 at sourceforge, here is the link to the project site. What makes MetaBuilder appart from using the standard Groovy options to make builders is that it follows an schema approach, in other words, you define which properties and the relationships between nodes as you go, in a similar manner as you define an object graph with XML.

This sample is extracted previously from my Silverlight Project. The source codes are highly configurable and you may customize it for you needs. Though it’s pretty simple but yet very good to act as a background for you application.

Stupid test huh? No way it would pass.. Think again. Try it yourself. Then go lookup the ASCII value of 1.

Things on Griffon and Greet have been chugging along. Just a soon as Groovy 1.6 Beta 2 ships I'll likely be ready for a 0.0 release, and such. (Remember, we are all computer scientists, and we start counting from zero). In the meantime here is an applet of the main demo for Griffon. This works best with the 6u10 release, and it may not work in your RSS readers either.

We recently had to translate a site to 13 different languages using Actionscript 2 ( arghhh ).The translation provided us was in Excel worksheets, and was just a nightmare to get right. We needed a way to quickly generate the translations as they changed.

A while back, I started talking about this idea for the Grails Podcast to run a "Groovy Awards" to recognise those people in our community that do an awesome job on the mailing lists, blogosphere, releasing plugins, and all that jazz. No big prizes - just some cheezy TShirts with a lot of love from the community.

Didn't see that one coming too, but yes Paul Krill, editor at large at InfoWorld, interviewed me a couple of weeks ago, precisely after publishing a couple of posts on JavaFx/Groovy on this blog. I'm humbled by this opportunity as you can find Jacob Lehrbaum and James L. Weaver among the article's contributors, they do know more about JavaFx (both platform and language) than me. Here is the article's link Can JavaFX make a play for rich Internet apps?

This is Part Three of a series of articles on Java.next. In Part Three, I will explore how the Java.next languages (JRuby, Groovy, Clojure, and Scala) support dispatch. For my purposes here, dispatch is a broad term covering various methods of dynamically choosing behavior: single dispatch, switch/case, pattern matching and multiple dispatch. These concepts are not generally grouped together, but they should be. They are used to solve similar problems, albeit in very different ways.

At the risk of turning this into a Groovy blog, here's an extended comment on a neat post by Jesse Wilson. With its Java-friendly syntax and command-line options, Groovy opens up some serious possibilities on the command line.

I’ve been looking at performance issues for the site we’re building at work. The database is obviously going to be the biggest bottleneck, so we’ve configured 2nd-level caching for read-only tables and some read-mostly tables. We’ve also configured query caching for obvious candidates.

Where i work, each with we’re assigned to a different tasks. My tasks this week are: test Beehive Webservices (i’ll post about it later) and test Oracle Coherence and Terracota. I decided to start with Coherence because it really called my attention — it’s a in-memory jcache compliant clustered cache.

The JSR-166y, which I described earlier in the post dedicated to the fork/join functionality is really amazing in how nicely it shields developers from dealing with threads. I've spent some time experimenting with another very handy capability of JSR-166y, which are Parallel Arrays.
