FizzBuzz Rails

This app is an implementation of the famous FizzBuzz problem. The problem is an interview problem used to weed out engineers that just plain can't code.

Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

Implementation

Everything lives in one controller at app/controllers/fizz_buzz_controller.rb. A lot of the implementation is client-side code. It's only been tested in Chrome on Mac OSX but...hey. Should work elsewhere.

Running the Application

In order to run the application in a development environment you'll need the following:

• rvm
• ruby 2.1.0

Actually getting up and running is pretty straight forward:

$ git clone git@github.com:cloudability/fizz-buzz-rails.git
$ cd fizz-buzz-rails
$ bundle install
$ foreman start
$ open "http://localhost:5000/"

Deploying the Application

The preferred deployment is as follows:

• ruby 2.1.0 (system installed)
• unicorn
• nginx

Details are:

• Nginx configured with Unicorn as the upstream.
• Multiple unicorn processes, controller via config/unicorns/nginx.rb configuration.
• Rolling restarts using the USR2 signal against the master unicorn process.
