Featured tutorial: Ruby for Newbies: Installing Ruby and Getting Started
Ruby is a one of the most popular languages used on the web. In this tutorial on Nettuts+ you will be introduced to Ruby, as well as the great frameworks and tools that go along with Ruby development. This serie will give you a look at why you might want to use Ruby for, as well as how to install it on your PC or Mac. But not only is this a great introductionary tutorial but it is also part of a complete tutorial serie that will teach you all aspects of ruby, and last but not least screencast are available which (in my opinion) makes it easier to follow each step of the tutorial.
