The recordings of the sessions from the SQLBits 8 in Brighton are just starting to come online, so if you’re bored at work you may want to take a look at them here:

We’ve now got over 200 hours of great SQL Server video content on the site, including lots of SSAS-related sessions. It is, of course, free to view and download with no registration required…
Similarly, the session recordings for TechEd are also available, and again there’s lots of interesting BI content there too. If you’re interested in learning more about the future of SSAS and BISM, the session on “What’s new in Denali for Analysis Services and PowerPivot” is a must-see.
