There's Bootcamp, primarily for New Hires, but which anyone can go to if they like. I teach a class there about how our Traffic management works - load balancers, and so forth.
There's also classes about learning to program on iOS or Android (those are generally a week long), or on Haskell or C++ or D (these are generally a few hours a week for a few weeks), and smaller ad-hoc 1-4 hour classes on things like the data pipeline tools, debugging and performance tools, and so forth.
There are also ad-hoc "Tech Talks" which just discuss general topics without a specific "learning" focus.
And then there are non-technology but career-oriented courses about time management, technical leadership, managing your manager, how to give good feedback, how to have difficult conversations, and so forth.
