For example: hiking trails and ski trails, public transit in some cities, and special information like a zoo map or a museum map. What I would like is to take a photo of such a map with my iPhone, supply my current location by tapping on the map, and enter the scale and orientation of the map — and then see my live position on the map as I move around, using GPS. The math behind this transformation would be very simple; I suspect the only complexity would be perspective-correcting the photo of the map. I have seen many apps that allow you to trace your route on Google Maps or some other pre-existing map, but none that allow importing a photograph of an arbitrary map. Does anyone know if this exists?"
The Future of Music Coalition — an advocacy group of musicians that fought radio consolidation — is assembling a lineup of name bands, such as R.E.M. and Death Cab for Cutie, to join the fight to keep the net neutral. The group will join net neutrality advocate Rep. Edward J. Markey (D-Mass.) for a teleconference today to kick off the campaign, which is called "Rock the Net." The campaign will include a petition and a series of concerts. The coalition fears that if companies are allowed to charge for faster access to the Internet, it will hurt the ability of musicians to get their music out to their fans, especially small, indie bands.
