Limit the frame-rate being targeted with requestAnimationFrame
/*
limitLoop.js - limit the frame-rate when using requestAnimation frame
Released under an MIT license.
When to use it?
----------------
A consistent frame-rate can be better than a janky experience only
occasionally hitting 60fps. Use this trick to target a specific frame-
rate (e.g 30fps, 48fps) until browsers better tackle this problem

Generate cryptographically secure random strings. Based on Kohana's Text::random() method and this answer: http://stackoverflow.com/a/13733588/179104
function random_text( $type = 'alnum', $length = 8 )
{
switch ( $type ) {
case 'alnum':

Custom markers (div-element) on google maps
Usage:
var myLatLng = new google.maps.LatLng(point.lat, point.lng);
var myMarker = new CustomMarker(myLatLng,map);
Implementation (mostly from googles example):
function CustomMarker(latlng, map) {
this.latlng_ = latlng;

Use ffmpeg and mp4box to prepare DASH-AVC/264 v1.0 VoD
See my DASH-IF presentation from October, 2014:
https://s3.amazonaws.com/misc.meltymedia/dash-if-reveal/index.html#/
1. encode multiple bitrates with keyframe alignment:
ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4
My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.
