If you have read some preformance tests on JavaScript loops, you may have heard that “while” is faster than “for”. However the question is how faster is “while”? Here are some results, but first let’s take a look on the JavaScript code. James Sugrue

Update: I just uploaded a new version of this tutorial that is much clearer and understandable. Empty your cache and check it out.

I just uploaded a new tutorial that explains how to use the new mouse lock feature that is included in Flash Player 11.2. This feature allows you to create infinite mouse scrolling while in fullscreen mode, which is essential for things like first-person shooter games.

Below is my third episode of HTML5 for App Developers series. In this episode, I cover how you can debug your JavaScript applications inside of Eclipse.

Debugger is available through a set of plugins that are available for Eclipse  from ChromeDevTools project on Google Code. Because of that you will need either Google Chrome or Chromium to make it all work.

Heroku the platform as a service (PAAS) company, very popular in the Ruby on Rails community, has now started opening up their platform to languages besides Ruby. They now offer support for Python, Java, Clojure, Node.js, and Scala on their new Cedar stack. Heroku's Cedar stack is still in beta, but that shouldn't stop you from trying it out, and that is just what I'm going to do. ...

When I first sat down to redesign my personal site I knew that I wanted to incorporate HTML5 Canvas somewhere in the layout. The problem was that I hadn't worked with canvas before and had to start from scratch. I went through the pain of learning every aspect of adding text, drawing shapes, importing image, etc... before I found the amazing canvas framework Processing.JS ...

Today I will tell you how to create different CSS3 image hover effects. I hope that you still remember our old tutorial. We used JavaScript there. Today I will try to make something similar using pure CSS3. In the resulting gallery page, we will have 9 images, each of them having its own hover effect.

As discriminatory as this is going to sound, this one is for the old-timers. If you started programming after the turn of the milennium, I don’t know if you’re going to be able to follow the trend of this post—not out of any serious deficiency on your part, hardly that. But I think this is something only the old-timers are going to identify with. (And thus, do I alienate probably 80%...

Happy Thursday to all you XAML-lovers out there! I'm back from the trenches with a new initiative aimed at teaching you how to use both new and existing controls from the Telerik RadControls for Silverlight and RadControls for WPF control suites. Starting today, every Thursday you'll be able to find a fresh batch of videos and sample projects highlighting a different control in a little series we're calling XAMLflix. The best part is that since we share a common codebase and API between our Silverlight and WPF suites you only have to learn how to use these controls once and can carry those skills over between frameworks. Pretty neat, right?

Say Hello, RadChartView

For anyone who has been with us for a bit, RadChartView actually first appeared in our Q3 2011 release with a beta tag stuck to it. Since then we've received a lot of feedback and wanted to use this as the pilot control for this new video content series, especially considering RadChartView goes official in our upcoming Q1 2012 release!

Rather than just direct you to the demos, while they are quite nice to look at, I wanted to give you a brief introduction to this new control with five videos meant to get you up and running. Without further delay, here's what we've got for today:

• Introducing RadChartView - A brief walkthrough how you can get up and running with nothing more than the Visual Studio designer and our designer widget for creating pre-defined charts. A must for anyone brand new to RadChartView! (Download the Project)
• Using RadCartesianChart - Walking through creating a new RadCartesianChart, including setting the chart Grid, picking out both horizontal and vertical axis, as well as defining a chart series and hooking it up to data. (Download the Project)
• Using RadPolarChart - Same as above, except this time with RadPolarChart! (Download the Project)
• Using the Pan and Zoom Behavior - Starting with a RadCertesianChart, see how quickly you can enable as well as customize the Pan and Zoom behavior.  (Download the Project)
• Using the TrackBall Behavior - After a quick review of the new RadCartesianChart, see how 5 lines of XAML can add the TrackBall behavior to your charts and how quickly you can customize how data is displayed. (Download the Project)

So grab a cup of coffee and take these videos and their sample projects for a spin. And courtesy of our shared API and codebase the projects are replicated between Silverlight and WPF, so regardless of which framework you are on you can see how these work.

Stay tuned for the next installment of XAMLflix next week!

There are certain perks to working as a tech journalist: coffee is free and plentiful, trade shows are equal parts fun and frantic, and most of all, we get the chance to play with lots and lots of new toys. I’ve personally had the luck to be able to swap handsets pretty much bi-weekly for the last couple of months, and find it kind of a bummer that Windows Phone 7 hasn’t really been embraced as the solid mobile platform that it is (I said it’s a bummer, I didn’t say we didn’t see it coming).

My previous post about Live Tiles showed you how you can use a PeriodicTask to update your Application’s Live Tile periodically from inside the phone. Now we are going to move a little beyond Application Tiles and move towards Secondary Tiles.

If you recall from my previous post Sync’ing OData to Local Storage in Windows Phone (Part 1), I had written a T4 template for my Windows Phone 7.5 (“Mango”) project to generate a proxy client needed to access both an OData service and local database on the device. My template was based on an existing T4 template,which was published in a blog post by Alexey Zakharov on Silverlight Show, that generated a generic OData proxy client. I had promised to publish my first stab a T4 template to generate this hybrid proxy. However, because my original template was based on Alexey’s OSS sample, it was taking a long time to get the go ahead to post it.

In my recent consulting assignment I was asked the question by one of the developer , that how can we get dynamic theming working in Prism application. My answer was that you can implement in the same manner as you do in the standard Silverlight application. But then he further asked that there are various regions in the RegionManager and how each views loaded in the different content regions can get unified theme , this encouraged me to try this out and see how it works.I started working on it and viola my answer was correct , there is no difference in implementing dynamic theming in prism specific app.

I have to admit that I may have rolled my eyes a bit when I first learned about the KnockoutJS library. It sounded too much like forcing a square peg into a round hole. Isn’t Model-View-Controller (MVC) already it’s own pattern? Does it make sense to apply something like Model-View-ViewModel (MVVM) to HTML? I already had enough issues dealing with MVVM on the platform it was designed for, XAML and C# (WPF and Silverlight). Some people simply didn’t get the pattern, others were pushing it without really understanding its benefits, and many applications completely and unnecessarily overcomplicated their implementation of the pattern. So before we talk about whether it makes sense in HTML-based applications, we first need to agree on what the benefits of the pattern are.

The Microsoft Windows 8 Client Editions aren’t even in beta, but the direction indicated at the BUILD Windows Conference in fall 2011 is clear: Expect many and significant changes. The BUILD Windows conference was itself a change, as a replacement for the Professional Developers Conference (PDC). The previews for Windows 8 Client version startled the audience, and with good reason: Windows 8 is different.
