This week on the GeekWire radio show and podcast, we talk about the UW football team’s use of high-tech cameras to gain a competitive edge; the Justice Department’s move to block the AT&T/T-Mobile merger; Amazon.com’s new Kindle feature for asking authors questions from inside books; and the second life for the HP TouchPad.

Our guest in the studio is Jeremy Irish, the co-founder and CEO of Seattle-based Groundspeak, the company behind geocaching.com, who talks about the rise of these high-tech treasure hunts.

And in our final segment we give the answer to last week’s Name That Tech Tune challenge, announce the winner, and try to stump you with a new sound, for a chance to win tickets to the upcoming Maelstrom International Fantastic Film Festival in Seattle.
