Random Roundup #3 – The internet's best things this week

In this week's Random Roundup - we chat: - unsending messages in WhatsApp, - passenger-carrrying drones in Dubai, - Uber getting into the ad game (what else will we do with all that time spent NOT driving autonomous vehicles), - a Podcast that explores piece by piece the making of this decade's top songs, - how your office will soon be tracking you everywhere except the bathroom, - a Snapchat trick no-one seems to know about - this week's winner of the internet.
