Quote from: cowpie34 on February 19, 2013, 05:13 pmThese scanners are for real and our government is already buying them. Fact. A girl at school has a smart pen with a camera on the end that records everything she hand writes and turns it into html at home. Also it has an audio recorder to record the teacher. These days it's weirder to not believe something happen eventually than not, but pico-second programmable laser is real now.I stand by my interpretation. I don't see how else they'd call it "programmable," if what they're selling is the opportunity for someone to figure out an algorithm that may not even exist, as in a way for a computer to detect everything on you when all it gets is a total mess of data -- nobody knows how to figure out how to compute that, but we know how to detect it just fine: light sensors are everywhere, but they can't analyze a fucking thing because that's hard as Hell.I still say this can't be done using current technology. Unless it's the most brilliant algorithm ever conceived of, it would have to be able to compute things at a level so detailed that the quantum interference patterns of who was holding your hand would actually start to interfere and become significant sources of error. To my knkowledge, we have no CPU that can compute such things in real time. They just aren't fast enough yet.In fairness though, I've never actually bothered trying to calculate the quantum wave function of a trillion atoms all at the same time. I've just looked at it. That was enough for me.
