I am currently exploring the possibilities of Ruby. Since this programming language is completely new to me I was looking for some quick hands-on tutorial. Via the Ruby site I found this online interactive tutorial which teaches you the very basics of Ruby. Another nice tutorial is the written tutorial “Ruby in twenty minutes” which can be viewed here.
If you are familiar with other programming languages like PHP, Java, Perl, Python, C or C++ you might want to check out this page, which provides an overview of the differences between Ruby and these languages.
Ruby can be downloaded from this page and is available for Windows, OSX and Linux. For OSX users: if you have Xcode installed there is no need to install Ruby again since Ruby comes with Xcode. Just open a console and type:
In order to execute myscript.rb.
