First of all you need to be able to run MAMP in port 80. This is a "heat check" if you don't have any process jamming http ports. You can check it like this:

sudo lsof | grep LISTEN

If you do happen to have any process with something like this *:http (LISTEN), you are in trouble. Before with adventure check if it isn't MAMP itself (yeah, you should close that beforehand)

ps <pid of that process>

If you don't see MAMP, you are in good hands, I have just the thing for you:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Session extends CI_Session{

	private $sess_use_redis = TRUE;	
	private $redis = '';

	public function __construct($params = array()) {
		//parent::__construct();
		$this->CI =& get_instance();

Two way iframe communication

The main difference between the two pages is the method of sending messages. Recieving messages is the same in both.

Parent

Send messages to iframe using iframeEl.contentWindow.postMessage Recieve messages using window.addEventListener('message')

Sort object properties by value (values are text)

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.

  font-family: $icon-font;  //set as a variable - it's whatever your icon font name is
  speak: none;

  font-variant: normal;

  line-height: 1;
