Ultimate Backup

Concerned about your data integrity (I mean YOUR DATA Integrity.)  Read “Fantastic Voyage” by Ray Kurzweil to maintain your physical body and wait a few years for nanotechnology to mature and you will be able to upload copies of your brain. Interesting Brain Fact from “The Mind Uploading Homepage”: How fast does the brain work? Not very fast by computer standards. An action potential (i.e., nerve impulse) lasts about 1 ms (millisecond).

Richard Feynman There’s Plenty of Room at the Bottom

(from the talk thatRichard Feynman gave on December 29th, 1959: Miniaturizing the computer - “I don’t know how to do this on a small scale in a practical way, but I do know that computing machines are very large; they fill rooms. Why can’t we make them very small, make them of little wires, little elements—and by little, I mean little. For instance, the wires should be 10 or 100 atoms in diameter, and the circuits should be a few thousand angstroms across.” (computing machines filled large rooms in 1959 - in 2005, well you know how much space computers need now. Can you imagine how small they will be in 10 years?))

From size to speed: Currently, the world’s fastest supercomputer is IBM’s Blue Gene/L which tops the list with a sustained performance of 70.72 Teraflops, or trillions of floating point calculations per second. This is almost double the performance of the former (now displaced from the top spot) leader — Japan’s Earth Simulator, which can sustain 35.86 trillion calculations a second.
