    You usually don't care what the variable encryption scheme is when you're cracking -- typically, there is a method of simply verifying that the password is accurate, which is what they're doing. (Brute-forcing keys is fairly foolish with modern encryption systems, but brute-forcing passwords isn't.)

  6. Re:I mention this on CERN Physicist Warns About Uranium Shortage · · Score: 1

    All of the electricity you produce gets used in ways that eventually result in it being heat. Solar panels also aren't currently efficient enough to cause that problem -- their albedo and efficiency are low enough that waste heat is generated by putting solar panels in place, rather than "stealing heat".

    (Seriously, how much heat is that thing going to put out?)

    As much energy as it consumes. For climate models, though, direct waste heat production is negligible compared to climatological effects (e.g., CO2).

  9. Re:Article is slightly wrong on Micro-Black Holes Make Poor Planet Killers · · Score: 1

    How the MBH interacts with matter is directly based on the size of its Scwartzchild radius. As this radius is significantly smaller than the atomic scale, it cannot capture atoms efficiently.

  10. Re:Lots of speculation. on Micro-Black Holes Make Poor Planet Killers · · Score: 2, Informative

    You actually picked the weak form of this argument.

    Our planet is small and not particularly dense. There's only one, and something like MBH or strangelets could be fairly rare. We could be lucky.

    Fortunately, there's an enormous field of stars, including large, dense neutron stars. Neutron stars are great at capturing errant particles, producing MBHes, and things like that. Looking at our estimates of the ages of these neutron stars, you can show that micro black holes cannot be responsible for stellar/planetary destruction.

  11. Re:Lots of speculation. on Micro-Black Holes Make Poor Planet Killers · · Score: 2, Informative

    This is a typical nonsense argument. You imply that because there are some things we don't know (e.g., questions to be answered by the LHC) that it's reasonably possible that we will encounter aberrant behavior that contradicts previous observation.

    There are few avenues for the MBH to be incorrect. They already assume that we are wrong about Hawking radiation (otherwise an MBH would boil off immediately). The only real options are that energy conservation is violated and the LHC is able to somehow create a heavy black hole, or the gravitational pull of a MBH is somehow enormously higher than its mass-energy would permit. (As the Schwartzchild radius is directly derived from its gravitational pull, there's not really any room for this to be wrong.)

    You are conflating providing for your own welfare with avarice.

    On the game theory track, it's well-known that people actually do not choose the "optimal" strategy -- they don't act exclusively in their own self-interest.

    Randians usually argue around this problem with tautologies.

    I realize this is Slashdot, so anything less than complete anarchocapitalism is no better than terrorists, but...

    Terrorists generally have to inflict actual harm to get their job done, and they have very little to lose. Capitalists don't have to inflict harm, they just need to make profits (they might inflict harm upon the way). They have a lot to lose: if people get pissed off enough, something will be done about them -- probably something that ruins their business.

  21. Re:Yeah, but it is reliable. on Chicago Court Throwing Out LIDAR Speeding Tickets · · Score: 1

    That's a qualitative argument. You claim it's possible for the speed reading to be incorrect, due to details of how LIDAR works. There are a lot more details about how the LIDAR gun works. Make the argument quantitative. By how much will the speed reading be incorrect for vehicles that are near or above the speed limit? (Vehicles well below the speed limit are, of course, not of interest.) It's unlikely for any useful measurement device to be perfectly accurate, but putting bounds on its accuracy is an approachable problem. There's a significant difference between a reading of 60 mph that's accurate to 0.1 mph and one that's accurate to 10 mph.

    We track 90% of the near-earth objects that have a possibility of causing global catastrophe. While there's certainly room for improvement, we've actually been doing quite a lot of looking.

    To give a sense of scale, global-catastrophic asteroids are 1 km in diameter; this one was 7 m.

    This seems like a nonsensical conclusion -- larger objects are easier to detect, both by virtue of being larger and, since they are a potential threat, are more worthy of attention and effort.
