Podcast: Privacy and Twitter

This podcast is from my weekly slot on Radio Australia Today with Phil Kafcaloudes and Adelaine Ng, wherein I chat about the issues of privacy concerning an inappropriate tweet, Google’s indexing of recent tweets, and some iPhone apps that let you spot celebrities.

I appear on Radio Australia Today every Friday at about 9.15 am Singapore time (that’s 0.15 GMT/UTC.) There’s a live stream of the broadcast here, or find out your local frequencies here.

The Bluetooth Gun

Bluetooth in the line of fire? New Scientist reports of a police gun invention that when fired will automatically send its position to fellow officers who can then, presumably, provide backup.

The idea is that when a police officer is holding his gun correctly — both hands on the weapon — he or she can’t easily reach for the radio. So inventor Kevin Sinha of Georgia, “has come up with a simple way around the problem and Motorola, which has made police radios for many years, has pitched in.” The invention involves a Bluetooth transmitter chip controlled by a sensor in the gun which detects when the firing pin is triggered. Whenever a shot is fired the gun sends out a signal to a GPS radio on the wearer’s belt which determines the wearer’s precise position and transmits a pre-recorded message along with the location.

An interesting use of Bluetooth (and GPS). Of course, knowing how hard it is to couple two Bluetooth devices, and their tendency to need “waking up” even if they are paired, I wouldn’t want to rely on it in hairy situations. Like being shot at, for example.

Mobiles As Walkie Talkies

Why do some people hold their cellphones like walkie-talkies, alternating between holding the mouthpiece to their mouth and then pushing the earpiece to their ear? I used to see people doing this in the early days of cellphone usage and thought it charming, but nowadays I see trendy, savvy dudes doing it. Like this elaborately prepared reconstruction:

Am I missing something, or are these cellphones so bad that folk can’t hear what the other is saying without it?
