    Put a closure on it

Sometimes you'll have objects that manage state along with event handling. This happens frequently in MVC apps. Let's start with a messy example:
var Launcher = function(rocket) {
  this.rocket = rocket
}

Launcher.prototype.isReady = function() {

    Asynchronous programming with Tornado

Asynchronous programming can be tricky for beginners, therefore I think it's
useful to iron some basic concepts to avoid common pitfalls.
For an explanation about generic asynchronous programming, I recommend you one
of the [many][2] [resources][3] [online][4].
I will focus on solely on asynchronous programming in [Tornado][1]. From
Tornado's homepage:

                Setup for an easy to use, simple reverse http tunnels with nginx and ssh. It's that simple there's no authentication at all. The end result, a single ssh command invocation gives you a public url for your web app hosted on your laptop.
              
          
    What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.
Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).
