on “IP Over QR Code”I'm guessing you're referring to MQTT. With smaller packet sizes it's more battery efficient than HTTP if you're making continuous network requests. Great comparison post here: http://stephendnicholas.com/posts/power-profiling-mqtt-vs-ht...

on “Show HN: Build live location sharing in your app with HyperTrack”Wikipedia has some more information on it, but for realistically printable QR codes (version 10), you can probably store about a hundred bytes. Alternatively you could use Video QR: http://stephendnicholas.com/archives/310 ;)
