// Media Queries in Sass 3.2
//
// These mixins make media queries a breeze with Sass.
// The media queries from mobile up until desktop all 
// trigger at different points along the way
//
// And important point to remember is that and width
// over the portrait width is considered to be part of the
// landscape width. This allows us to capture widths of devices
// that might not fit the dimensions exactly. This means the break

Rails 3.2 ships with a simple FileWatcher that only reloads your app if any of the files changed.

Besides, it also provides a mechanism to hook up your own file watcher mechanism, so we can use tools like FSSM that hooks into Mac OS X fsevents. This is an example on how to hook your own mechanism (you need Rails master, soon to be Rails 3.2):

1. Copy the 2_file_watcher.rb file below to lib/file_watcher.rb

2. Add the following inside your Application in config/application.rb

if Rails.env.development?

JavaScript Class Syntax

Let's build a JavaScript class syntax from first principles. For the purpose of this exercise, let's assume that the purpose of the class syntax is to add much-needed sugar to common JavaScript idioms.

Let's start with how JavaScript "classes" work today:

// this is a constructor
Person = function() {
 this // `this` is a new instance of Person
