#SOLID Principles with ruby examples
##SRP - Single responsibility principle A class should have only a single responsibility.
Every class should have a single responsibility, and that responsibility should be entirely encapsulated. All its services should be narrowly aligned with that responsibility, this embrace the high cohesion.
##OCP - Open/closed principle Software entities should be open for extension, but closed for modification.
Install phantomjs (http://phantomjs.org)
brew has a recipe for phantomjs, but it has moved on to version 2.0.0, and we still require 1.8.2 (at newest), and we can't get that old and dirty with brew anymore.
On a Mac:
mkdir -p ~/root
wget https://phantomjs.googlecode.com/files/phantomjs-1.8.2-macosx.zip -O ~/root/phantomjs-1.8.2-macosx.zip

#Setting up Nginx on Your Local System ###by Keith Rosenberg
##Step 1 - Homebrew The first thing to do, if you're on a Mac, is to install homebrew from http://mxcl.github.io/homebrew/
The command to type into terminal to install homebrew is:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Hosting services like Heroku and Amazon EC2 are nice. That is, until they cost money. Some things are worth running on your own hardware, especially when the cost and Terms of Service requirements outweigh the expense of rolling your own hosting.
I am writing this because I recently had to figure all this out in order to host a personal blog off a Raspberry Pi, and I thought I'd share what I learned. This guide assumes that you already know how to install Ruby and you know how to use Rails. If you don't, look those up first before coming back to this guide.
