It's been a busy past few days in the tech world, so we're going to kick off the show by playing "Silicon Tally" — the game where were try to stump people with numbers from the week's tech news. Our guest this Friday: Melissa Kirsch, editor in chief of Lifehacker. Afterwards, we'll look at virtual reality's strong presence at the annual Tribeca Film Festival, and then chat with researcher Molly Sauter about the laws governing cyber crime.
