Notes from "Shut Up and Take My Money" by Josh Kaufman

Link: http://vimeo.com/71250239

Every business has five parts:

1. Value creation
2. Marketing - "here i am, this is what i do, here is why you should be interested"
3. Sales - doing transactions
4. Value delivery - what does it take to give what i've sold to the customer?

Hello World

This post walks through the Pony "hello world" program.

Code

First, the program in all its glory.

actor Main

jeremyheiler

// This is a pony program that will print the first arg provided to the program.

// Every pony program requires an actor called "Main"
actor Main

  // This is a constructor for the Main actor named "create".
  // It is a convention (supported by syntactic sugar) to call constructors "create".
  // In general, a constructor can have any name that begins with a lower case character.
  // However, the Main actor requires its constructor to be called "create".
