Convert float coordinates to DMS (degree, minutes, seconds). Ex.: convert_coord_to_dms(e.g. 21.305728, -157.859647) -> 21° 18' 20.6208" N, 157° 51' 34.7292" E
function convert_coord_to_dms (lat, lon) {
/*
Se Lat é positivo é Norte, senão Sul
Se Long é positivo é Leste, senão Oeste
*/
var lat_orientation = lat < 0 ? "S" : "N",
lon_orientation = lat < 0 ? "W" : "E";
function get_dms(decimal) {

fernandosavio / unserialize.php
Last active November 26, 2015 18:19 — forked from phred/unserialize.php
Simple reliable and non-regex method to unserialize PHP session data
<?
//
// This is the result of about an hour's delving into PHP's hairy-ass serialization internals.
// PHP provides a session_decode function, however, it's only useful for setting the contents of
// $_SESSION. Say, for instance, you want to decode the session strings that PHP stores in its
// session files -- session_decode gets you nowhere.
//
// There are a bunch of nasty little solutions on the manual page[1] that use pretty hairy regular
// expressions to get the job done, but I found a simple way to use PHP's unserialize and recurse
// through the string extracting all of the serialized bits along the way.

Find the N-th fibonacci number using Binet's Formula.

function fibonacci_nth(i){
var v5 = Math.sqrt(5),
Phi = ( v5 + 1 ) / 2,
phi = Phi-1;
return Math.round( Math.pow(Phi, i) / v5 - Math.pow(-phi, i) / v5 );
