/*
    A basic implementation of the Publisher/Subscriber design pattern.
    Developed by @addyosmani and @integralist

    Example Usage:

                    // Create subscriber function to be called when topic publishes an event
                    var testSubscriber = function (topics, data) {
                        console.log(topics + ': ' + data);
                    };

How to make faster scroll effects?

• Avoid too many reflows (the browser to recalculate everything)
• Use advanced CSS3 for graphic card rendering
• Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

The idea is to have nginx installed and node installed. I will extend this gist to include how to install those as well, but at the moment, the following assumes you have nginx 0.7.62 and node 0.2.3 installed on a Linux distro (I used Ubuntu).

In a nutshell,

1. nginx is used to serve static files (css, js, images, etc.)
2. node serves all the "dynamic" stuff.

So for example, www.foo.com request comes and your css, js, and images get served thru nginx while everything else (the request for say index.html or "/") gets served through node.

3. nginx listens on port 80.
