Ruby ♦ Weekly Issue 19
December 9, 2010

If I get it wrong, though, I hope that you'll be hitting me up at rw@peterc.org! OK - on with the news:

Matt Reider of Engine Yard runs through using the Vagrant VM building tool to easily set up a virtual environment running Ruby and Rails (using Engine Yard's supplied Vagrant environment) and get an application up and running in it.
