  1. It's also inappropriate for Slashdot (at least, what Slashdot used to be) to dismiss discussion of ideas simply because they're unlikely. If you read, that's actually Loeb's point. I'm a bit surprised he's doubling down on the aliens hypothesis, but his real point is that there is value in thinking about unlikely possibilities scientifically.

    I find our binary friend amusing too, but his style is a bit sinister. He uses ridicule incite, but lots of people use ridicule to stifle discussion. Talk is cheap. Have a drink or light up a doobie and engage in some speculation. Sometimes it leads useful places.

  2. Life itself is an anti-entropic process. As long as there's usable energy around, a life form need not decay. When the energy runs out, well, I don't think I'd call that aging. I also don't think I'd characterize a long life with zero decay followed by sudden death as "a rate of ageing."

  3. True... on the other hand, not only have we shot several somethings onto interstellar trajectories, but there are reasonably serious people currently intending to do that as a primary mission.

  4. Our binary friend is a famous Slashdot troll of the modern era. Don't worry, he's not angry, dismissive OR a moron. He is pretty entertaining when you realize that he's doing it on purpose.

  5. Shielding. If you're going to shoot something through interstellar space you're probably going to want to put your port-a-potty inside a nice big asteroid to absorb all the weathering.

  6. Other way around. Fahrenheit and Celsius are both dead European dudes. The Fahrenheit scale is named after the former, and the centigrade scale (from the Latin centum) was renamed in 1948 to honour the latter.

    Both scales are interval scales, which means that x and x+1 are equidistant no matter what x is. However, the actual values on interval scales (especially the zero) are pretty arbitrary (Fahrenheit put it at the freezing point of an equal mixture of salt and water, the Celsius scale has it at the freezing point of pure water; actually, prior to the mid 1700s the zero was at the boiling point and it got cooler as you counted up). At least in temperature scales, that's made explicit by putting "degrees" as part of the unit: degrees Fahrenheit or degrees Celsius.

    Kelvin is another dead guy and also the name of a ratio scale of temperature. Ratio scales are a step up from interval scales, with one of their most important features being that they have a real zero. Zero Kelvin is absolute zero, the coldest possible temperature. Ratio temperature scales don't use degrees; "degrees Kelvin" is wrong.

    Celsius, like so many other SI units, was redefined a while back based on the Kelvin scale, so zero degrees C is no longer the freezing point of pure water, but rather is 273.15 Kelvin.

  7. Yay, a pedantic thread!

    Actually, c is the speed of influence. Causality is either a principle or a relationship, neither of which can have a speed.

    "Unidentified Floating Object"

    Floating involves buoyancy force in some medium.

    Space is "unidentified *falling* object". Unless of course it's aliens, then it's "unidentified falling-not-quite-as-it-should-be object."

    https://haveibeenpwned.com/ asks for your e-mail address and then tells you if it's included in any known e-mail / password pair dumps. Entertainingly, it also tells you which dumps, and, if it's known, which organizations they came from.

    They could be harvesting e-mail addresses I suppose, but I pretty much assume that ship sailed a long time ago.

    Maybe you were entering your credentials into the wrong shady website?

  10. Hedge funds take people's money and invest it on their behalf (they're expected to pay it back some day). Many religions do the same, except for the paying back part. The Vatican, for example, has an extensive investment portfolio.

  11. Yes. Perhaps they have real principles and they were hurting them back then as well as now.

  13. Probably. Apple tried to launch an ad network and it failed, so they staked out a differentiating position in favour of personal privacy. It's widely suspected that it's hurting them: Siri not retaining to everything ever said to it, for example. Individuals don't seem to care enough about their privacy to make it a winning business strategy, but maybe they can get some laws passed in favour of it.

    It has nothing to do with encryption. QKD is about making a communications channel where you know if messages are being intercepted. The most useful thing anyone could think of to do with that is to exchange encryption keys.

    Of course the REAL question is why Alice and Bob couldn't exchange a key in a conventional way, but they COULD run a fibre optic cable through the Holland Tunnel and build QKD hardware to put on either end of it.

    I watched the trailer. It looked like a decent shooter with a kind of space cowboy / Firefly flavour with a very subtle touch of manga. I'm not surprised it pissed off Battlefield players.

    I don't see that the page you linked to says you can ride bicycles on sidewalks. It outlines several different types of bike paths, none of which are sidewalks (one is separated from a main road by, for example, a sidewalk). It does say that bicycles of all types must obey the rules of the road (no driving on the sidewalk?).

    Apparently the best predictor of electoral success is candidate appearance (not money spent). So many people DO base their vote on zit counts. Although beautifying might not be the best idea for political ads. The predictor for US presidential elections was the candidate who looked "most presidential," which might not be the same as "youngest" or "prettiest."
