Ruby Weekly Issue 19
December 9, 2010
It's issue 19 of Ruby Weekly! As Don Draper recently said in Mad Men: "You might see a little advertising in this newsletter soon." It's true, but I'm sensitive to people's attitudes to advertising and you won't ever see a newsletter published by me filled with trash and sloppy graphics. If I get it wrong, though, I hope that you'll be hitting me up at! OK - on with the news:

Phusion Passenger 3.0.1 Released
OK, OK, it's a point release, but it's a slow news week and Passenger is a critical piece of Ruby webapp infrastructure. The 3.0.1 release brings faster compilation/installation, error message improvements, library upgrades, and RailsEnv and RackEnv are at last treated equally on Apache.

Virtualize This - Instant Rails in a Virtual Box
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.

Dynamic Inference of Static Types for Ruby [PDF]
