IBM developerWorks has a nice article that answers the question of What’s the secret sauce in Ruby on Rails?  Although almost a year old, I think the article does a nice job of explaining why Rails has become so popular in such a short period of time.  Having recently jumped back into Rails, many of the author’s points hit close to home.

Dan Benjamin has updated his awesome instructions for Hivelogic - The Narrative - Building Ruby, Rails, Mongrel, and MySQL on Mac OS X. I’ve used these instructions in the past and they work great. The advantage of his method is that you compile the software from source (don’t be afraid it’s really easy) so you have great control over your configuration and upgrades will be easier.

Rails vs Django is a nice evaluation of the two most popular web application frameworks. Rails uses the Ruby scripting language while Django uses the Python scripting language. Both are very capable and offer a unique set of features. This evaluation shows you how long it took to write the application and compares the lines of code along with some syntactical differences.

Project RIDE-ME is yet another Ruby on Rails development environment for Windows! This IDE is similar in look and feel to Visual Studio so should be familiar to those making the switch from .NET to the Rails framework. The project is free and open-source.
