Like many developers, I've been intrigued by the hype around Ruby on Rails, but of course I don't have a Linux box handy and don't feel like setting up Apache, etc to try it out. What's a lazy programmer to do?

Enter Instant Rails, especially designed for Windows developers. From the description:

Instant Rails is a one-stop Rails runtime solution containing Ruby, Rails, Apache, and MySQL, all preconfigured and ready to run. No installer, you simply drop it into the directory of your choice and run it. It does not modify your system environment.

You can download Instant Rails here.
