We hosted a puppet hackday at our office last week. We were lucky enough to have Luke Kaines (the creator of Puppet) give a talk (via justin.tv and slideshare).
Another highpoint: Julie Tsai from SlideShare gave an interactive tutorial on how to use puppet to automate some simple system configuration. Everyone who came made it through the hands-on exercise and successfully configured their own server. We’re going to be sharing the recipe for how to set up the server used in this exercise so that others can use it when they run their own Puppet tutorials.
