Comment Enough. This is a peer reviewed paper. (Score 1) 299

I can only add to this back-and-forth that the paper in question has been peer reviewed. You all are not dealing with Shawyer's self-published non-reviewed paper here. This is physics, an actual hypothesis. Those of you who disagree have to consider that your comprehension of photon-photon "annihilation" and momentum conservation might be flawed. In any case, we have a way forward; all the previous negative responses had in common (endlessly) was the fact that physics had to be completely wrong for a resonant cavity drive to provide propellantless propulsion. Now we have a way in which EM drives do not violate physics. And - it's emminently testable. Even if Shawyer is completely valueless here, he might have triggered a new way of thinking about momentum transfer, a hack in the universe we can use for propulsion. We need one badly.

Comment Long length and haystack. Weird chars not needed. (Score 1) 637

Length, not weirdness, is the key to uncrackablity. For easy remembering, embed a simple password in a hell of a long string of repeating characters broken up by odd interruptions of non-repeaters. For instance:

=-4=-=-(repeat lots)=-=-yourpassphraseorword=-(repeat lots)=-88=- (repeat lots) -=-
is bloody impossible to crack with any tables.

Most people think password breaking is like the way people crack safes. One spin, crack, another spin, crack, until the code is broken. Password crackers have *no way of knowing* if they are hot or cold. They must guess the entire string at one go. That means length, not oddness, is the primary defense. You can have a simple one word password.... if you embed it in a string of simple and easy to remember character repetitions (broken at random intervals by a deal breaker to foil crackers trying for character padding repetition guesses). Steve Gibson came up with it, and it works, if the site allows for long passwords.

If someone bugged your keyboard, all bets are off, of course.

Note: Slashdot's filter error won't let me type repeating characters.
