Sick of limiting your iTunes purchases to five authorized computers? Us, too. Well, thanks to DVD Jon, the guy who cracked DVD encryption way back in 1999, you can now download MP3 files from iTunes DRM-free and use them any which way you please. DVD Jon's new app is called doubleTwist and is currently available only for Windows machines, but it strips the Apple DRM and allows you to synch music with devices like your Sony PSP, Nokia N-Series phones, and even the Amazon Kindle. Lifehacker reports that there's a five percent loss of audio quality on the DRM-stripped files, but that seems like a small price to pay for freedom.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
