I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:

Kibana 3 against ElasticSearch 1.4 throws an Connection Failed screen. The error text says to set http.cors.allow-origin, but it misses out the important http.cors.enabled: true

Working config:

$ grep cors elasticsearch-1.4.0.Beta1/config/elasticsearch.yml
http.cors.allow-origin: "/.*/"

To properly edit an accounts DocumentRoot go to /var/cpanel/userdata/username/ (replace username with the actual cPanel username for the account), then edit the file domain.com (where domain.com is your primary domain name).

You will see something like this in that file:

documentroot: /home/username/public_html

You will also see the cgi-bin area in this section:

scriptalias:

	window.console.clog = function(log){
	var message = typeof log === 'object' ? '%cLooks like you\'re trying to log an ' : '%cLooks like you\'re trying to log a ',
	style = 'background:url(http://i.imgur.com/SErVs5H.png);padding:5px 15px 142px 19px;line-height:280px;';
	console.log.call(console, message + typeof log + '.', style);
	};

	DKIM is DomainKeys Identified Mail and is used in mail servers, such as Postfix or Sendmail to sign e-mails and thus authenticating the sender so that a forgery can be detected. It also reduces the possibility of an e-mail being flagged as spam, but it's not a definite prevention.

	A much simpler method is using SPF (Sender Policy Framework) which, in a nutshell, verifies the sender IP address.

	According to the internet, using both should result to ????, PROFIT !!!.

	SPF does not need a specific configuration. Whitelisted servers are listed in a DNS record, TXT or SPF, and an example record is:

	example.com. IN TXT "v=spf1 a mx ~all"

	var ko = require('knockout');

	ko.components.register('simple-name', require('./components/simple-name/simple-name.js'));

	ko.applyBindings({ userName: ko.observable() });
