Tutorial I gave at LISA 2014 http://goo.gl/G0TLfJ
This is a talk about running puppet in the enterprise, or at scale. The original title of Mastering Puppet was Puppet in the Enterprise, the talk was to present the ideas in the book.

Talk I gave at puppetcamp seattle 2014 http://goo.gl/b2NISc
In the first part, Troubleshooting Puppet talks about problems with communication, how to make sure puppet is running and connecting to a master. In the second part, the talk moves on to compilation and catalog application issues. Real world solutions are presented throughout.
This keeps coming up so I thought I'd share one trick we've used to figure out if there are stale nodes out there. These are nodes that are failing to update for various reasons that won't be reported in your reporting mechanism. One of the common causes is an expired or revoked certificate. The agent never gets far enough to report a failure.
