At Tech Ed Orlando a bunch of the RDs got together to record ten minute videos called GrokTalks.
The idea of the GrokTalk came from the thought that often in conferences we find a useful tidbit in a session that is only about ten minutes long... so why not do only those ten minutes?
My GrokTalk focused on the new error handling capabilities of SQL Server 2005 and how you can use them to recover from a deadlock inside of a stored procedure. You can take a look at my video and the others at http://www.groktalk.net/.
