[Are cheap Yagi Antennas worth buying?]

Lay it on the line: Is the Yagi in the hackshop one of these? Has anyone tried it?

[Disappearing episodes?]

Has anyone else noticed that certain episodes are missing from the archives here, on youtube, and on revision3? For instance, the yagi build episode seems to be MIA (Possibly because it's in the store?), and another episode from a con in San Diego (Featuring a very clever phone hack, where some students tracked phone users...) is also MIA. WTF?

[Episode with interview about phone info-gathering hack?]

Does anybody else remember the episode where Darren interviewed a guy, I think it may have been at the conference in San Diego, about a phone hack? If I remember correctly, the hack had to deal with gathering the info about cellphone location by querying the towers, then producing a massive database where they figured out locations based on the transitions from tower to tower. I'd like to re-watch that episode, but since it happened (I think) a year or two back, I'd hate to have to wade through all those videos again.
