Intercom user_hash

• Code for generating the user_hash value for Intercom's Identity verfication (Note: Identity verification was prevoiusly called Secure Mode)
• Based on http://www.jokecamp.com/blog/examples-of-creating-base64-hashes-using-hmac-sha256-in-different-languages/#ruby
• When creating this for mobile, the final output needs to be in lowercase (the web version accepts both upper and lower case)

Remember that your secret key should never be exposed to the public

• So Javascript code below should only be used for testing unless modified and used to run on a server

Here's a step by step guide to convert a Virtualbox .ova to a Vagrant box.

1. List your VMs to find the VM id you want to convert:

$ VBoxManage list vms
"testing" {a3f59eed-b9c5-4a5f-9977-187f8eb8c4d4}

2. You can now package the .ova VM as Vagrant box:

/**
 * Very simple way to check if a file exists on this domain.
 * Use with the jQuery library.
 *
 * Important: 	Works only on the same domain. 
 * 		Cross-domain-requests have to be done in another way (see JSONP)!
 *
 * Use: console.log(   "/data/list.json".fileExists()  );
 */
String.prototype.fileExists = function() {

/**
 * Based on http://www.wenigersh.com/blog/post/maintenance-mode-for-symfony-2-applications
 * 
 * Includes support of user permisson check (here: check if user has role ADMIN), so admins can still surf the site while in maintenance mode
 * Be aware that if you clear the cache (to start maintenance in prod environment) your sessions might be cleared as well, so people get logged out
 * The config.yml will move the sessions to /app/sessions/[environment]
 * 
 * Also be aware that you need at least Symfony 2.6 for this permission check. For older versions the call is different
 * @see http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements
