Ruby Track on CodeAcademy
Written by Sue Gee   
Monday, 15 October 2012

Codeacademy's latest new track offers a tutorial introducing  Ruby, the object-oriented scripting language you can use on its own or as part of the Ruby on Rails web.

Like other Codeacademy courses, Introduction to Ruby is a "hands-on" course and is aimed at beginners with no previous knowledge of either Ruby or computer science.

The first lesson takes you through a series of short exercises which give you instructions as to what to type into an on-screen editor. When you Run your code you see feedback in the lower window.

Currently there are five lessons, based on Ruby 1.9.3.:

  • Introduction - 16 exercises
  • Control Flow - 17 exercises
  • Loops & Iterators  - 18 exercises
  • Data Structures - 16 exercises
  • Methods, Blocks & Sorting - 19 exercises

Each lesson has a project in which you create small programs and this is where learning the language becomes interesting and practical.  Again these are broken down into small sections, with between 6 and 8 exercises.

The site is sometimes slow, probably due to being overloaded with enthusiastic learners, and does crash with errors from time to time. There is a Q&A forum where students can ask questions and be answered by other students.

So is Ruby a good choice for the beginner?

According to Codeacademy's announcement:

Ruby is currently used at places like Google (for 3D modeling), NASA (for running simulations), and even right here at Codeacademy (as part of the Ruby on Rails web framework). And with its active community of developers and great gem support, it's ideal for building all kinds of useful programs quickly and easily.

 

In addition to the new Ruby track, Codeacademy has also released three new Python units, using Python 2.7, complete with lessons, projects, and challenges. While these are available to anyone who has set up a free Codeacademy account they have been created specifically for the new Mechanical MOOC Python class that starts today.
