Ok, I just got this email twice. Something's definitely funky with the
mailing list software. Someone asked to be notified if that happened
again.

With the invisible shield screen protector it should be as well protected as

In Ubuntu and Fedora, check out "blueproximity" -- you sync your
bluetooth device with your PC, and set a proximity level in feet (1..30)
and when the device goes out of ran

One can also measure the signal strength. I don't know how accurate that is.
KDE has a tool that locks the desktop if you (and your bluetooth phone
ofcourse) are to far away.

Very unlikely.
But some bluetooth devices can tell you the signal level of any peer.
With that, you could aproximate the distance.
Would be interesting

Not that I know of, but two cooperating Freerunners can exchange
information about their GPS coordinates
Hi,
I don't think that's feasible. To measure (with 2 devices) you need
two very synchronous clocks and a very exact measurement. Because the
signal travels with approximately the speed of light (about 300.000
km/s), an error of 1µs is an error of 300m. There are a lot of reasons
why this is not fe

Hi List,
I wondered, can two bluetooth devices ping each other and find out their
distance or relative speeds?
Not in the first place as some security tag to unlock my PC or house, but to
use in a game-like setting. Imagine some live role playing game, where weapons
