Quicksort in JavaScript
/**
* An implementation for Quicksort. Doesn't
* perform as well as the native Array.sort
* and also runs the risk of a stack overflow
*
* Tests with:
*
* var array = [];
* for(var i = 0; i < 20; i++) {
* array.push(Math.round(Math.random() * 100));

Here’s an example of my current web app user agent, device, and/or feature detection approach. I tend to inline this in the page header just before the stylesheet as part of the distribution build. A benefit of this approach is that detection is done early without any external dependencies. It’s also straightforward to modify or extend while you…
env = (function() {
var flags = {}, ua = navigator.userAgent, el = document.createElement('div'), video = document.createElement('video'), audio = document.createElement('audio'), root = document.documentElement, i
function flag(names) {
names = names.split(' ')
for (i = 0; i < names.length; i++)
flags[names[i]] = true
}
function classnames() {
var names = [], name
for(name in flags) if (flags.hasOwnProperty(name))

A PHP Imagick wrapper class that makes image manipulation simpler by making some decisions and by adding new functionality. The `getMainBorderColor()` method is specially interesting. With it you can calculate which color is the most frequent in the lateral borders of an image. I used it to set a background for an area that could possibly be lef…
