Get even numbers from array using recursion instead of a loop, and without mutating the original array

	Array.prototype.evens = function() {
	var arr = this;
	var out = [];
	var count = 0;
	var even = function(arr, out) {
	if (count <= arr.length - 1) {
	if ((arr[count] % 2) === 0) {
	out.push(arr[count]);
	}
	count++;

Short unique ID (Ruby)

	t = DateTime
	id = t.now.strftime("%Y%m%d%k%M%S%L") # Get current date to the milliseconds
	id = id.to_i.to_s(36) # will generate somthing like "5i0sp1h4tkc"

	# Reverse it
	id.to_i(36)

Naively pluck keywords from text

	<?php
