  5. Re:What about lasers? on Position-Based Quantum Cryptography Proved Secure · · Score: 1

    Stimulated emission is not perfect cloning. The monkey wrench which prevents lasers from violating the no-cloning rule is the non-zero probability of spontaneous emission. See this paper:

    Experimental Quantum Cloning of Single Photons

    Although perfect copying of unknown quantum systems is forbidden by the laws of quantum mechanics, approximate cloning is possible. A natural way of realizing quantum cloning of photons is by stimulated emission. In this context, the fundamental quantum limit to the quality of the clones is imposed by the unavoidable presence of spontaneous emission.

    So, taxes pay for the roads, the sidewalks, etc. If you pay taxes, and you park where these fucking abominations are, then you get the pleasure of paying another tax on top of what you've already paid to park there.

    It isn't a tax, it's a deterrent to prevent too many people trying to park in the middle of downtown. In my city, there are areas with meters and areas with free parking. Guess which areas I can never find a parking spot?

    You're not paranoid enough. I figure the satellite isn't actually meandering out of its orbit at all -- that part is just fabrication. The idea is to provide a plausible scenario which gives a justification for demonstrating some heretofore unknown technology that can blast this thing from 35,000 kilometers away, without it looking like pure sabre rattling.

  9. Re:Care about roundoff? You better know types. on Matplotlib For Python Developers · · Score: 1

    Isn't it fair to say that if you're worried about roundoff noise in repeated calculations, you've passed the point from being just a scientist to a someone who should be concerned with general programming theory and conventions, and hence at least familiar and comfortable with notation that denotes type?

    I understand types. The question here is which type the literal value "5" or "2" ought to be. Right now, these literals are interpreted as integers. A lot of people would prefer the default to be some real type. I'm talking about the syntax of the language, not suggesting that integer arithmetic is useless.

    Just out of curiosity, I understand the Shuttle is not designed to go to Geosynchronous orbit. Is it merely a matter of thrust that keeps it Low-Earth Orbit or are there other issues as well?

    Leaving aside the obviously huge amount of fuel you'd need... the problem is conservation of energy. It takes a LOT of energy to reach geosynch orbit. This energy doesn't just vanish when you want to turn around and come back. As you fall into Earth's gravity well, that potential energy transforms into kinetic energy. Result? You're going to slam into the atmosphere going 10 or so times faster than the shuttle can handle.

    What the hell good is math accurate out to 10 places when I only have an 8 bit A2D on an input in the process loop?

    Because I don't want to accumulate roundoff noise in each fucking calculation? Nobody is disputing the importance of significant figures. But intermediate rounding is just throwing noise into the mix for no good damn reason.

    Oh shut up. The guy was a TEENAGER.

    I have a friend who swerved as he was coming over a rise and a truck was hanging ass into his lane (he was going a bit too fast). Swerved across the road, then back, hit the gravel, spun it, flew into an orchard, and miraculously flipped end-over-end 6 times keeping a perfectly straight line down the aisle. He crawled out the busted window and walked away from it.

  16. Re:Python for Scientific use on Matplotlib For Python Developers · · Score: 1

    What the hell are you rambling about? Long numerical calculations do not involve intermediate rounding except in very specific circumstances. Data always have some amount of noise to them -- rounding at inappropriate moments AMPLIFIES the noise. The direction to which a value rounds depends which side of 0.5 the fractional part falls on. If the exact value (which we cannot know precisely) is very close to 0.5 in the fractional part, then whether the value rounds up or rounds down may depend entirely on the noise.

    That's exactly the output you should expect for integer division, which is what 5/2 is asking for.

    On what planet? Just because C works that way, and Python works that way (at least until now), doesn't mean it's the best way, or the most useful way, or that it could never be changed.

    That's EXACTLY the point being made here -- people are touting Python as a scientific computing platform, but the result "5/2 == 2" is almost never what you want when doing scientific calculations. So from the standpoint of scientific coding, some features are really not ideal.

    Or someone/company decided to liquidate their stock holdings maybe because they figured that the Greece crises would hit US stocks too or financial regulatory reform coming out of Congress would adversely harm the market. Of course they aren't the only player in the market, so all the automatic trading software realized that the massive sell-off made little sense given their risk parameters and lots of hedge-funds decided to invest in those now under priced stocks.

    That could explain a correlated dip in prices. But it does not explain, for instance, how ACN lost about 99.98% of its value. It went from $40.00 to $0.01. Somebody rode the fucking lightning on that one, and I don't mean the electric chair
