Jeremy has been developing applications with Ruby and Rails for a little over five years, but before that he tortured himself with PHP, C#, Python, VB, and other instruments of destruction. After finding the light, he worked with Ruby for a while and penned Mr. Neighborly’s Humble Little Ruby Book (soon to be published by No Starch). Since then he has continued writing software, books (such as Ruby in Practice for Manning), open-source code (such as dcov, context, and more), presentations for numerous Ruby conferences and user groups, blogs at, and basically done anything he can to sharpen his Ruby (and Rails)-Fu. He likes good food, good times, and a mean game of Wii Sports Resort Tennis.


Rails 3 is the clear choice for new apps, but is it worth porting your apps running on Rails 2.3 and older? Yes. I'll give you reasons why, a quick checklist for a weekend port, and walk through a real app upgrade.
