Generally one implements notifications by listening for events on specific models but if one wishes to have a single global message interchange, it could be done as follows:

var pubsub = new Backbone.Model;

View1 = Backbone.View.extend({
  initialize: function(){
    pubsub.bind('custom event', callback);
  }

#You should do all your LAMP development in a Virtual Machine

##Here's Why:

Many of us develop on Macintoshes. There are many reasons for this, but one of them is that it's based on a Unix platform of some sort. This allows us to run common server software such as Apache, Ruby, Python and Nodejs on our Macs.

Our computers become powerful develoment machines similar to the servers our apps will eventually live on.

Sometime we start our computer only to find Apache won't start, or MySQL can't create a PID file, or we've updated to Mountain Lion and Apache needs to be reconfigured. Death!

Reduce database queries (http://www.catswhocode.com/blog/speeding-up-your-wordpress-blog-7-effective-solutions)
It is important to reduce unecessary queries to your database as each query take a few milliseconds to execute. First, you might want to know how many queries your blog execute in order to display a page. To do so, paste the code below in your functions.php file. Once done, just have a look to your site footer to know how many queries has been executed and how many time it took to completely load the page.

add_action( 'wp_footer', 'tcb_note_server_side_page_speed' );
function tcb_note_server_side_page_speed() {
  date_default_timezone_set( get_option( 'timezone_string' ) );
  $content  = '[ ' . date( 'Y-m-d H:i:s T' ) . ' ] ';
  $content .= 'Page created in ';
  $content .= timer_stop( $display = 0, $precision = 2 );
  $content .= ' seconds from ';
