General key themes:

• Hiring is really hard. You’re not just hiring a “Rails Engineer” or a “Python Programmer” you’re hiring someone who can help you change the world. Tell them why! Talk about the hard problems you’re solving. 2/3 of these talks give ideas and insight into hiring from sourcing to actual interview processes.

• Rewriting systems is hard. People think they are going to replace their broken down horse and buggie with a bullet train and this often ends up in disaster. Successful rewrites require an incremental approach that takes months/years and often runs way over schedule. 2/3 of these talks go over how to handle rewrites not only from a high level technical perspective but a cultural/management perspective as well.

 * Inspired by the infamous beginning of Zork I.
 * Reading the source will obviously spoil the game.
 * The goal is to somehow kill the troll.
 * Oh yeah and: This is my first GO program! Which would be
 *   my perfect excuse for the bad code quality1!
 * Here is a solution/transcript:
