A thorough introduction of continuous delivery from Stas Zvinyatskovsky (Yahoo!). If you're releasing once a quarter (month (week!)) and are frustrated about it, watching his talk would be 45 minutes very well spent.
On the other hand, if you're already practicing this with confidence, and have a fully automated process to deploy to production multiple times per day, there might not be that many news in here for you. The reason is that Stas wanted to keep the whole talk very approachable, so he didn't have much time to go too deep.
Still, there are lots of good starting points and FAQ answers in there about tools and techniques Yahoo! is already using successfully to cover the whole stack of continuous delivery.
Update: the recording of this talk is available here:
