Maybe this is a pro for some people, but there is really no computer science taught in this course aside from the basic structure of a programming language.
You'll come away from this course with a general knowledge on how to program in Ruby, but it won't really teach you how to create a real-world project or how such things work.
Tutorials are presented as videos, making them easy to follow / see what's going on at each step. Many people find this format less daunting and easier to take in than traditional text based tutorials.
The first video explains how to setup Ruby on your machine. A lot of tutorials tell you about the language but leave you in the dark on how to get it up and running, creating a stumbling block before the first post.
