The TechEd material is fantastic and there are lots of good sessions to choose from. I’d like to point you in the direction of the Business Intelligence track at TechEd, and here is a sample of the great content to view:
The 12 Reasons to Love Microsoft SQL Server 2012 with Dandy Weyn, Sean Boon and Thomas La Rock
The Dirty Dozen: Windows PowerShell Scripts for the Busy DBA by Aaron Nelson
Building Self-Service BI Applications Using PowerPivot by Julie Strauss
and my personal favourite:
BISM: Multidimensional vs. Tabular with Marco Russo and Alberto Ferrari
There are too many to list here, so please head over to Channel 9 and take a look!
