(1) Unfortunately, the push notification software PushBullet is only pushing notifications on Android devices due to a bug with IOS currently. Additionally, you must have a more recent version of Python (e.g. 2.7.12) to run this software, which additionally requires new Numpy and Scipy packages, the installation of which are beyond the scope of this tutorial.
