Getting Cassandra and OpsCenter to run on OSX using Docker

Getting Docker installed

Why not make life easy...? Install Homebrew

The 'brew' package lets you install applications through the commandline, making compiling and setting up new apps a breeze.

Since docker cannot run on osx natively, we will need to build a virtual machine

Ingredients: 

2 stewpans - one is main = 5 litres, second is for beet

potatoes - 12 items of average size, neither big nor small

Letter to a Young Haskell Enthusiast, by Gershom Bazerman.

Condensed from: http://comonad.com/reader/2014/letter-to-a-young-haskell-enthusiast/

The following letter is about tendencies that come with the flush of excitement of learning any new thing. It is written specifically, because if we don't talk specifics, the generalities make no sense. It is a letter full of things I want to remember.

You’ve entered the world of strongly typed functional programming, and it is great. You want to share the great things you’ve learned, and you want to slay all the false statements in the world.
