Setup new Mac with OSX Lion from scratch

These commands are good as of 2011-07-27.

Install Xcode 4

The download/install takes a while so start it first. When it finishes downloading you will still need to run it to complete installation.

iTerm2

Really the nicest choice for a terminal on OSX right now, especially with Lion style full screen support.

WebSockets + Reflux + React

Using WebSockets, React and Reflux together can be a beautiful thing, but the intial setup can be a bit of a pain. The below examples attempt to offer one (arguably enjoyable) way to use these tools together.

Overview

This trifect works well if you think of things like so:

1. Reflux Store: The store fetches, updates and persists data. A store can be a list of items or a single item. Most of the times you reach for this.state in react should instead live within stores. Stores can listen to other stores as well as to events being fired.
2. Reflux Actions: Actions are triggered by components when the component wants to change the state of the store. A store listens to actions and can listen to more than one set of actions.
