FizBuz - shorter & sweeter
View fizz_buzz.rb
# the classic FizzBuzz exercise, implemented with Ruby syntax
# at first, I wrote a script similar to the JavaScript exercise on Codeacademy.com
# Needless to say, the chain of if..else... statements just feels wrong.
# Below, with comments, is far superior code, modeled off http://www.rubyquiz.com/quiz126.html
# Start with an array of integers. We'll pass each integer individually to the block.
(1..100).each{ |i|
# Set an empty string as a default.

Converting RGB to HEX in Ruby
View gist:2423065
# Beginning Rubyists: simply run >> ruby hex-convertions.rb to see examples
# or use irb to build the code on the fly
# you can convert HEX to DEC using the method .to_i(base),
# which converts a string to a decimal number from the specified base number
puts "00".to_i(16)
puts "FF".to_i(16)
