Java 6 Update 11


Sun has released Java 6 Update 11, which contains the JavaFX runtime. The official release of the JavaFX SDK will be tomorrow (12/4/2008). The JRE itself is also available from Sun's auto-update site.

Visual WebGui 6.2.2 SDK Released

The 6.2.2 release provides compatibility to MS Silverlight RC0/RTW, and now supports development & deployment of web applications with the latest Silverlight technology. As stated before, Microsoft has released Silverlight 2 with weak backwards compatibility to previous Silverlight versions, which resulted in some presentation issues with the Silverlight layer that are now solved.

The new release also includes the Visual WebGui WinForms-like designer allowing simple and cost-effective Web development, and the new ASP.NET Control wrapper wizard introduced earlier this month.

Version 6.2.2 provides further stabilization to 6.2 which brought new standards in developer experience. for more information please read the official announcement.

The new Visual WebGui SDK is now available for download.

JSON - 3D Proof of Concept

A few weeks ago I wrote a post on the concept of using JSON for creating 3-D models (You can read the first JSON 3D post here). I have created a proof of concept based on MooCanvas to allow for IE support. This proof of concept is also based on the 3D cube demo for MooCanvas with some modifications.

For this proof of concept the important function is Load3D which loads and translates the JSON 3D object.

 		function Load3D(obj, translateX, translateY, translateZ){
			scene.shapes[(obj.type + ObjectCounter + "")] = new Shape();
			var p = scene.shapes[(obj.type + ObjectCounter + "")].points; // for convenience
			for(var a=0; a<obj.vrt.length; a++){
				p[a] = new Point(((obj.vrt[a][0])+translateX), ((obj.vrt[a][1])+translateY), ((obj.vrt[a][2])+translateZ));
			// Create Shape From Points
			for(var a=0; a<obj.fac.length; a++){
					scene.shapes[(obj.type + ObjectCounter + "")].polygons.push(new Polygon(
					[ p[obj.fac[a][0]], p[obj.fac[a][1]], p[obj.fac[a][2]], p[obj.fac[a][3]] ],
					new Point(obj.nrm[a][0], obj.nrm[a][1], obj.nrm[a][2]),
					true /* double-sided */,
					[obj.mat[a][0], obj.mat[a][1], obj.mat[a][2]]


For the JSON 3D object you would pass it into the Load3D function. While in this example I have put the JSON 3D object in the HTML, you would load the JSON 3D using Ajax (or a script tag) in the real world.

			var ThreeDobj = {
			Load3D(ThreeDobj, 0, 0, 0);

You can see the proof of concept here.

The proof of concept has been tested on Google Chrome, FireFox 3 and IE 7. It may work on other browsers (it should work on Safari and Opera), but has not been tested.

Full Silverlight compatibility with the upcoming VWG 6.2.2


As announced before on Visual, the 6.2.2 release which is expected to be released later this week will provide compatibility to MS Silverlight RC0/RTW.

As you probably know, Microsoft recently released a new version of Silverlight which provides almost no compatibility backwards to older Silverlight versions. This means that all the released VWG Silverlight applications will not work with this new MS Silverlight version.

Furthermore, Microsoft triggered an automatic update mechanism inside Internet Explorer to have the Silverlight ActiveX update without asking. As a result, all computers with MS Silverlight client installed on it have the new version, unless the user manually removed it.

Since Microsoft released this incompatible version, our Silverlight development team has been working very hard on modifying Visual WebGui to get in line with those changes and support the new MS version once again. We were also promised by Microsoft director in Silverlight group that this was the last back compatibility breaking.

Ruby on Rails 2.2 Released


The web application framework that broke the mold (and made Ruby famous in the process) has released version 2.2.

Key features in the update include:

  • Ruby 1.9 compatibility. Among the key features that Ruby 1.9 brings (at least for users of the "main" C-based implementation) is a single native thread for every Ruby thread. Finally. Now Rails applications can run with much less memory consumption and better processor utilization. Will you miss all those extra Mongrel instances? Probably not.
  • Thread safety. Important updates to the framework have been made to ensure thread safety. This will be a big boon to JRuby users (who have been dreaming of this for a long time), but C Ruby users will have to wait for certain dependencies to be updated before they can really enjoy its benefits (most notably those--ahem--with large amounts of C code). To enable mutli-threading, add config.threadsafe! to your config/environments/production.rb. (Note, however that this will disable automatic loading by ActiveSupport::Dependencies.) Plan on becoming more familiar with Mutex.
  • Internationalization. i18n has been baked into the framework, making localization of your application much easier.
  • ActiveRecord now has a proper connection pool.

The release notes are here.

Rails 2.2 now requires RubyGems 1.3.1, so you'll want to make sure to update it (gem update --system) first. To install the new version, do something like the following:

gem install rails
rake rails:update

Arun Gupta from Sun also gives a nice overview of how to run Rails 2.2 on GlassFish v3 Prelude and JRuby 1.1.5.

The new Visual Studio integration demonstrated on Webcast

On Nov 24 at 9am PT, Visual WebGui will be presenting another Webcast as part of the MSDN Webcast series:
Integrating Visual WebGui into Visual Studio Simplifies Development and Saves Time and Money

In this webcast, we will demonstrate the new integration, usability & compatibility features introduced with version 6.2.

Attend this webcast to learn how the Visual WebGui platform increases productivity when developing AJAX DHTML and Microsoft Silverlight applications, saving time and money. And learn about Visual WebGui's complete integration into the Microsoft Visual Studio development system, a consolidated installation process, and the opportunity to use Microsoft Visual Studio Express Editions for software evaluation and trials.

Recently I have been looking at 3D as it pertains to the web and controlled through JavaScript without the aid of plug-ins (this is a topic that interests me as in my early programming I created a lot of 3D applications). While Canvas is currently good for 2D rendering (on most browsers and IE with a little help from Google) we are still a ways off from cross browser Canvas 3D support. While I have found a few 3D engines written with Canvas, they all seem to bomb on IE (even with Google's IE Canvas script).

Even if a good 3D solution was available for the web we still have the issue of being able to load all the models for a scene. This got me thinking a bit about how the loading of scene information could be made to work on the Web.

The concept that I have come up with is fairly simply. You would load a map of the scene (this map may could be stored in JSON and could be made to work as a BSP [Binary Space Partitioning] tree) and on the map you would have various check points. Each checkpoint would load the needed models using JSON.

Below is an example of what the JSON for a cube may look like.


While this is just a concept and we are still waiting on the technology to make the possible. It is interesting to think of how we may be able to use JSON - 3D in the near future.

You can see a demo of Canvas 3D by using JSON for models here (this works on Firefox, but may not work on other browsers).

I Want My Type Information (Back)


As Neal Gafter explained a while ago, there is a backdoor in Java's generic type erasure:


Google Guice makes use of this backdoor to enable the construction of a generic type literal (or Super Type Token): its TypeLiteral class. Now (the soon to be released) Guice 2.0 goes a step further: it can inject a TypeLiteral into your class, thereby reifying your generic types (well, sort of). All the details of the changes to are here.

As Neal Gafter also explained, java.lang.reflect.Type really should be retrofitted. Until then, Guice offers you a little help.
