Increasingly, users have come to expect that applications they use continue to respond while the application processes information in the background. To achieve the best responsiveness, you need to build applications to be as asynchronous as possible. In the past, creating asynchronous operations consisted of passing callback delegates or lambda expressions to indicate what action to take when an action completes. These can lead to an unmanageable mess of spaghetti code.

The newest member of the jQuery family of projects is jQuery Mobile. A good way to describe what jQuery Mobile is to think of it as jQuery UI for mobile devices. If you have wanted to write mobile-optimized UIs over your applications, jQuery Mobile is a library that you will want to add to your bag of tricks. Like jQuery UI, jQuery Mobile is themeable. This article makes two assumptions. First, you are familiar with jQuery and second, you are familiar with jQuery UI. If ...you are not familiar with jQuery or jQuery UI, I suggest that you take a moment to familiarize yourself with those libraries. Fortunately, the websites for these projects (jquery.com and jQueryUI.com respectively) are replete with comprehensive documentation and code examples. jQuery Mobile is no different. The official website for jQuery Mobile is jquerymobile.com. As of this writing, jQuery Mobile 1.0 Beta 3 has been released. Its beta status notwithstanding, jQuery Mobile is ready for primetime and has been incorporated into many applications already. In this article, I will cover what you need to get started with some simple examples that illustrate how to create one page and multi-page apps. In addition, I’ll touch upon the theming capabilities in jQuery Mobile.See More

In a previous article, I wrote about how simple it is to deploy an ASP.NET MVC Web Application to Windows Azure using Team Foundation Service hosted at tfspreview.com. In this article, I will build on those concepts and show you how to build and deploy a simple Node.js website to Azure using Git as the source code repository. One of Azure’s core strengths is its openness. In addition to the .NET SDK, Azure has SDKs for Java, PHP, Python and for the purposes of this artic...le, Node.js. That openness also extends to Azure hosted Virtual Machines where Ubuntu, openSUSE and SUSE Linux are supported in addition to core Microsoft server technologies such as Windows Server 2012/2008 and SQL Server. In this article, I’ll provide a brief primer on Node.js, Git and how those technologies are first class citizens in Azure. One technology you will not find in this article is Visual Studio! We’ll use Notepad as our sole developer IDE!See More

I read somewhere that nearly 80% of all data has some location-related aspect to it. Common business questions in data include: Where do we ship these orders? Where are flood plains located and what rainfall amount are problematic for them? Where are vendors and/or customers located? What delivery route should we use? Can we track using GPS? Where are voting districts located? Where are the best hospitals located? Where are the sales regions that produce the most revenu...e? And so on. It is highly likely that a significant portion of the data you work with has a location-related aspect to it. Visually presenting this information could lead to better management decisions or possibly uncovering trends that were not evident before. A good application can present this information using a location-oriented approach. That is where Microsoft Virtual Earth fits in.See More

Microsoft released Visual Studio 2008 and .NET 3.5 in November 2007. I have good news and, depending on your perspective, I have either bad news or good news. If you were hoping ASP.NET 3.5 would be released with a variety of new controls, features, and architectural changes then I have bad news for you. If you’re still trying to master all the controls, features, best practices, project structures, deployment options, and architectural changes introduced when ASP.NET we...nt from version 1.1 to 2.0, I have good news for you. Don’t get me wrong, there are plenty of new things you will want to take advantage of in ASP.NET 3.5, but the changes from ASP.NET 2.0 to ASP.NET 3.5 are more additive and incremental than monumental.See More
