ffmpeg youtube live event rtmp stream from raspberry pi with raspi camera (raspivid)
  1. compile ffmpeg for arm https://github.com/fiorix/ffmpeg-arm
  2. create youtube 'live event'. get rtmp url + session id
  3. run this:
raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/<SESSION>

you can tweak -b and -fps to your liking. the settings above work well for 1080p. by not specifying width or height we get the full 1920x1080 resolution from the raspi camera

Very Simple IndexedDB Example
// This works on all devices/browsers, and uses IndexedDBShim as a final fallback
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;
// Open (or create) the database
var open = indexedDB.open("MyDatabase", 1);
// Create the schema
open.onupgradeneeded = function() {
var db = open.result;
var store = db.createObjectStore("MyObjectStore", {keyPath: "id"});
// This function is called immediately. The second function is passed in
// as the factory parameter to this function.
(function (factory) {
// If there is a variable named module and it has an exports property,
// then we're working in a Node-like environment. Use require to load
// the jQuery object that the module system is using and pass it in.
if(typeof module === "object" && typeof module.exports === "object") {
factory(require("jquery"), window, document);
}
// Otherwise, we're working in a browser, so just pass in the global
