The training this year has a lot of advanced topics that will bring a smile from anyone working in a DevOps environment. Tutorials on Jenkins, build-your-own-cloud, and a Googler will teach a class called "SRE University".
There are a lot of specific technology tutorials: IPv6, file systems, Puppet, Python and a RaspberryPi class for people that want to move it beyond being a toy.
I noticed a bunch of new security tutorials.
I'll be teaching my new class 'Evil Genius 101' which is about how to convince your coworkers to get on board with your evil plans for world (or at least network) domination.
