I still love this site on MSDN UK,  MSDN Nuggets.

I quote -

"Don't have the time to read a 10-page how-to article or watch a full length webcast? Try an MSDN Nugget, a webcast that takes you step-by-step to discovering new functionality or exploring a hot developer topic, all in 10-15 minutes. View them online now or download for later reference."

Its a great reference for all sorts of Microsoft related development, like creating managed code stored procedures, writing mobile application.   All in bite size chunks...
