An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

Everything is broken up by tag, but within each the selectors aren't particularly ordered.

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:

-webkit-appearance:none;

/* Sample JavaScript file added with ScriptTag resource. 
This sample file is meant to teach best practices.
Your app will load jQuery if it's not defined. 
Your app will load jQuery if jQuery is defined but is too old, e.g. < 1.7. 
Your app does not change the definition of $ or jQuery outside the app. 
Example: if a Shopify theme uses jQuery 1.4.2, both of these statements run in the console will still return '1.4.2'
once the app is installed, even if the app uses jQuery 1.9.1:
jQuery.fn.jquery => "1.4.2" 
$.fn.jquery -> "1.4.2"
*/

Order of evaluation in PHP

Yesterday I found some people on my [favorite reddit][lolphp] wonder about the output of the following code:

<?php

$a = 1;
$c = $a + $a++;
