Anyone who has ever worked with JavaScript for any amount of time should be familiar with the task of creating custom JavaScript objects.

A friend of mine recently posted  Levenshtein distance algorithm implementation using Javascript. It is part of our WMSuite web development framework. Post can be found here .

Microsoft Windows SharePoint Services continues to provide the solution platform for the next version of Microsoft SharePoint Products and Technologies. Microsoft Windows SharePoint Services (version 3) takes full advantage of Microsoft ASP.NET 2.0 and the core Microsoft .NET 2.0 run time. Components such as the Web Part Framework and Web Virtualization are now provided by the .NET run time rather than by Windows SharePoint Services. This change allows Windows SharePoint Services to focus on providing SharePoint services rather than .NET services.

The new features and added programmability support in Microsoft Windows SharePoint Services (version 3) provide a wealth of development opportunities. The topics in this section provide a quick overview of new features and enhancements, ranging from content types and new list abilities to workflows. To see it click here .

You probably already saw title like this. It is quite favorite disscussion topic in these days. AJAX is very popular and "cool" in web development area. JSON over XML – this is just a brilliang example of misunderstoding, because if JSON will be used for communication it won't be named AJAX but AJAJ (Asynchronous Javascript and JSON). I know that Javascript and JSON are nearly the same, but the origin of this technology was about XML… From my point of view it is the same whan I saw "AJAX application" and after small inside look I can see only POST or GET for communication with server usualy using HTML fragments to direct inserting into updated part of UI.
