Mark Shropshire presented on Docker. That presentation led into a deeper discussion into LXC (Linux Containers). Through some live demoing, the group experimented with Docker's architecture.
A couple of weekly email newsletters were brought up by participants. Jason Edgecombe mentioned the great Devops Weekly newsletter. The Hacker Newsletter was also brought up as a nice resource.
