BBtv: Playing the Building


Today’s episode of BoingBoing TV visits [David Byrne]’s Playing the Building installation which we covered before. The video provides some insight into the artistic process: they wandered around and whacked things with mallets to see what sounded good. They use counterweighted motors to vibrate cast iron girders and columns. Many of the empty radiators are being struck by solenoids. He says the installation is very approachable because people realize that even if a skilled musician sat down they wouldn’t be any better at playing the device.

Cold boot encryption attack video


We haven’t made a regular habit of watching BoingBoing TV, but lately they’ve been covering topics we’ve been interested in… not the dolphin pr0n. In yesterday’s episode they talked to Jacob Appelbaum and members of the EFF about the cold boot encryption attack. The attack involves dumping the contents of memory to a storage device by power cycling the system. Cooling the memory chip with compressed air helps preserve the integrity of the data. The attacker can then search the data to find encryption keys protecting the contents of the hard drive. A fool proof solution to mitigate this attack hasn’t been developed yet. You can read more about cold boot attacks at the Center for Information Technology Policy. The BoingBoing TV episode, bizarre editing and all, can be downloaded directly here.
