Just testing out gist and the embed option.

nick_name.rb

first_name = 'ed'
nick_name = 'ebot'
puts "Hello, my name is #{first_name}, but everyone calls me #{nick_name}."

nickName.java

// The same idea, but in java
String firstName = "Ed";
String nickName = "ebot";
System.out.println("Hello, my name is " + nickName
  + ", but everyone calls me " + nickName + ".");
