the junk reflex

M:  "Hey, want this bucket with 20 gallons of vacuum tubes? I'm throwing it away."
jwz:  "You can't throw that away, those are neat! I'll take it."
...30 minutes later...
jwz:  "What the fuck is wrong with me? I have absolutely no use for this junk."

Want some vacuum tubes? Get them from the back room at DNA before the garbage gets taken out.

Earplug provides steer-by-tongue control

A device that detects ear-pressure changes -- to determine how a person is moving their tongue -- should let people with extremely restricted movement control a wheelchair or computer more easily.

However, some improvements are needed before tongue movements can be detected when a person is active. "If you are running or moving around, the bones of your skull conduct too much noise," says Vaidyanathan, "but I think improving the design of the earplug and the mathematical signal processing could address that in future."
