Instagram shows how Hyperlapse stabilizes your jittery videos
Instagram has already revealed a bit about how Hyperlapse turns your shaky handheld footage into smooth time-lapses, but what if you really want to know what makes it tick? Don't worry -- the company will happily satisfy your curiosity with a deep dive into the app's inner workings. Ultimately, you're looking at a significant extension of the Cinema tech used in Instagram itself. It's still using your phone's gyroscope to determine the orientation of the camera and crop frames to counteract any shakiness. The biggest change is in how Hyperlapse adjusts to different time-lapse speeds. It only checks the positioning for the video frames you'll actually see, and that crop-based smoothing effect will change as you step up the pace.

Hail nearby medics with the GoodSAM smartphone app
In a serious medical emergency, action in the first few minutes can be key to a positive outcome. An ambulance might be only a few miles away, but what if someone with medical training, who could provide immediate care while the cavalry's on route, was sitting just next door? It's this kind of scenario a doctor with London's Air Ambulance service had in mind when he created GoodSAM, an Android and iOS app that sends out a request for any nearby professionals to lend a hand in an emergency.
