Nightc||ed's Beginner Ruby Guide
Introduction
Ruby is a cross-platform interpreted language which has many features in common with other ‘scripting’ languages such as Perl and Python. It has an ‘English language’ style syntax which looks somewhat Pascal-like at first sight. It is thoroughly object oriented, and has a good deal in common with the greatgranddaddy of ‘pure’ OO languages, Smalltalk. It has been said that the languages which most influenced the development of Ruby were: Perl, Smalltalk, Eiffel, Ada and Lisp. The Ruby language was created by Yukihiro Matsumoto (commonly known as ‘Matz’) and it was first released in 1995.

That's the textbook definition of the Ruby language, covering basic language relationship, history and syntax.
Some things to note
As mentioned in the introduction, I highly recommend learning Ruby if you already know Perl or Python as it's basically a cleaner python.
Spoiler: Example
Ruby:
Python:
Perl:
Code:
puts "This."
sleepPython:
Code:
print("As compared to this.")
wait = input()Perl:
Code:
print "Or this.\n";
sleep;Terminology
Ruby terminology is pretty easy to understand but I'll drop this here for later use in the tutorial
(Would be a lot more convenient if we had the table plugin, @Onion)

Argument
An argument to a method is a named variable in the method's definition, or an object passed to a method when called.
Array
An ordered collection values, often assigned to a variable. in Ruby, the array takes the place of all ordered collections. They act as arrays, lists, stacks, queues, etc...
Benchmark
An evaluation of how fast computer software can run.
Boolean
An expression that outputs either True or False
Data Structure
A way of storing data in memory for later use
Define
"Define" is used to express how and when variables, classes and methods are first available for use.
