Homebrew and package management

Mike McQuaid joined us to catch us up on the latest in Homebrew and the recent 1.0.0 release. We talked about no more `/usr/local` — Homebrew moves to `/usr/local/Homebrew` to keep `/usr/local` cleaner, auto-updates, the growth of the Homebrew community and how it has grown to almost 6000 unique contributors, and more.
