Aspects of AJAX
You probably know already about Gaia AJAX Widgets.
Featured on dnrTV, Gaia widgets provide a comprehensive set of ASP.NET server controls with rich AJAX capabilities--from Button to AutoCompleter and from modal dialog boses to panels. If you're a "classic" ASP.NET developer just should feel just at home. The programming model is kind of familiar and little intrusive--I'd say--in your coding practices and habits. Gaia also pushes to the limit the idea of aspect-oriented AJAX. What's that? It's code, in the end, based on the principle that you can dynamically configure "aspects" of a given control. Yes, it's close enough to what MS calls extenders. But in Gaia it is a native part of the framework.
A few days ago, the Gaia people (btw, a young company based in Norway) launched a competition with an interesting award: €10000 (sort of $14K). The deal is to create an open source AJAX collaboration web site (or similar) to make the world a little better place. Definitely, an ambitious project :)
And, of course, you must use Gaia AJAX Widgets for the purpose.
Instead of just focusing on food (and gain weight) in the forthcoming holiday season, why not just trying something else? :)
