New Scientist Technology Blog

A few interesting stories on the New Scientist Technology Blog this week. Including: schoolkids who are using high frequency mobile ringtones, because old teachers can't hear them; Google's plans to get your computer to listen to what you're watching on TV (starting to get a bit intrusive, I feel); and online gaming doing a deal with US cable TV so that you can watch people playing Halo on the telly, as a spectator.
