ubiset

Reading Time: < 1 minute

Building your own ubiset:

– buy a modern 3G phone
– install the following software:
* Google Maps (http://www.google.com/mobile/)
* Tweets60 (http://www.tweets60.com/)
* Glogger Lite (http://m.glogger.mobi/)
* Fring (though it’s a battery drain)

This set gives you access to a lot of info on the road. You can keep in touch
and document (Glogger) what you see. Fring is quite on drain on battery, so be
careful with that. My mobile was sucked empty in 1 day instead of normal
3-4 days (at that point of its life).

Also, read EFF (Electronic Frontier Foundation) instructions about how
to preserve your location privacy. At least if you decide to give away
information you know how it can be (ab)used.

faster preliminary GPS location by synching devices

Reading Time: < 1 minute

Since there’s going to be time that we have at least half a dozen Bluetooth-enabled devices with GPS capabilities in any given 100m radius area, then why not use this information
concentration to benefit all?

Usually a single device has some trouble getting GPS signal,
and the initialization takes time; sometimes it’s just 5-10 seconds, but it may well
be in the order of several minutes in worst case. The idea is that devices could poll others to give them information about the correct location. A single device could then
average the given answers and find out the location to a certain degree of certainty and
resolution. By filtering out the most deviant answers, devices could protect themselves
from being fooled.
