Trigger Spotify with osascript

/Applications/Spotify.app/Contents/Resources/Spotify.sdef

# read-only
osascript -e 'tell application "Spotify" to player state'                  # stopped,playing,paused
osascript -e 'tell application "Spotify" to current track'                 # The current playing track.
osascript -e 'tell application "Spotify" to artwork url of current track'  # Image data in TIFF format.
osascript -e 'tell application "Spotify" to artist of current track'       # The artist of the track.

I have tried a lot of solutions for IP-camera streams.

Old solutions

Vitamio.https://github.com/yixia/Vitamio-iOS
Result: random crashes and not working cameras
https://github.com/kolyvan/kxmovie
Result: compile time error. I haven't successfully integrated it to my project.

Git/Github step-by-step Workflow

Step-by-step guide for creating a feature or bugfix branch, submit it for code review as a pull request and once approved, merge upstream. This guide is intended for internal developers with push access to all relevant repos.

You should understand rebasing and squashing. For a very good explanation on rebasing and squashing with pull requests see How to Rebase a Pull Request. Also worth reading is the Hacker's Guide to Git.

Setup

Angular2 + JSPM cheat sheet

First time setup

install jspm beta: npm install -g jspm@beta
set up your project: jspm init
install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	import React from "react";
	import useMutableReducer from "./useMutableReducer";

	const reducer = (draft, action, state) => {
	switch (action) {
	case "increment":
	draft.count++;
	break;
	case "decrement":
	draft.count--;

	# -- mode: python --
	{
	"targets": [
	{
	"include_dirs": ["<!(node -e \"require('nan')\")"],
	"target_name": "TimerAndPromise",
	"sources": [
	"timer-and-promise.cc"
	],
	"conditions": [

	function Bucket(capacity, level){
	this.capacity = capacity;
	this.level = level \|\| 0;
	}
	Bucket.prototype.fill = function(){
	this.level = this.capacity;
	}
	Bucket.prototype.discard = function(){
	this.level = 0;
	}

	/* bling.js */

	window.$ = document.querySelectorAll.bind(document);

	Node.prototype.on = window.on = function (name, fn) {
	this.addEventListener(name, fn);
	};

	NodeList.prototype.__proto__ = Array.prototype;
