To send all request to a single mongrel instance use the following syntax:

<VirtualHost *>
        DocumentRoot /var/www/yourwebsite
        ProxyPass / http://localhost:4000/
        ProxyPassReverse / http://localhost:4000/
<VirtualHost>

Make sure everything is well grounded and that the signal cables are far away from the power cables or else you get a horrible whine coming from the alternator, especially if you put a sub in the boot.

If you’ve got a Honda Civic 7th Gen 2000-2004 then this guide should help, It definitely helped me. Just watch out for the yellow cables, they are for the airbags and are best left well alone (Oh.. and disconnect the negative battery lead, to be on the safe side)

Most of the sites i currently work on use jQuery to add additional functionality without being to obtrusive to people that have JavaScript turned off.

JavaScript has to be turned on for Google’s code to work! So we can safely inject the code when the page is fully loaded and clients that have JavaScript turned off will be none the wiser.

Place the following code into a site wide file that loads after jQuery and change the tracker code (gaTrackCode) to the one you received from analytics.

// google analytics tracking code
jQuery(document).ready(function($) {
  var gaTrackCode = "UA-123456789";
  var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");

  jQuery.getScript(gaJsHost + "google-analytics.com/ga.js", function(){
    var pageTracker = _gat._getTracker(gaTrackCode);
    pageTracker._initData();
    pageTracker._trackPageview();
  });
});

If you ever find your self writing ugly code like this:

db = Database.new
db.open
orders = db.fetch_orders
db.close

It may be worth looking at ruby’s block syntax so you can instead write:

Database.new do |db|
  orders = db.fetch_orders
end

Just check if a block is given inside the initialize method and wrap it with the open and close method calls.

class Database

  def initialize
    if block_given?
      open
        yield self
      close
    end
  end

  def open
  end

  def close
  end

  def fetch_orders
  end
end
