It is a tool for checking foreground and background color combinations of all DOM elements and determining if they provide sufficient contrast when viewed by someone having color deficits. All the tests are based on the algorithms suggested by the World Wide Web Consortium (W3C).

Come hear how the Reactive Extensions ("Rx") framework takes care of the difficult parts of asynchronous programming by viewing asynchronous computations as push-based collections. Instead of focusing on the hard parts, developers now can start dreaming about the endless possibilities of orchestrating and synchronizing computations at a high-level of abstraction. In this session we cover the design philosophy of the new Reactive Extensions for JavaScript, rooted on the deep duality between the well-known iterator and the observer design patterns. From this core understanding, we start looking at various combinators and operators defined over observable collections, as provided by Rx, driving concepts home by a bunch of samples. Democratizing asynchronous programming starts today. Don't miss out on it!

Scott sits down with Erik Meijer from the Cloud Programmability Team to hear about the Reactive Extensions for .NET (Rx).

Rx is a library for composing asynchronous and event-based programs using observable collections.

Did you know that you don't have to link to an external image file when using an element in HTML, or declaring a background-image in CSS? You can embed the image data directly into the document with data URIs.

ASP.NET lib to bundle multiple JS & CSS files (if you're not using Telerik of course)

Routing != Rewriting

If you are building an ASP.NET web application that's going to get thousands of hits per hour, the execution overhead of Linq queries is going to consume too much CPU and make your site slow. There's a runtime cost associated with each and every Linq Query you write.
