    Actually, the majority of bitcoins is being horded right now. Stuffed into a wallet and put into a safe or an encrypted file, only to be used years from now.

    If you think short-selling is evil, wait till someone figures out how to short bitcoins.

    You already can. Some exchanges (e.g. Kraken) allow you to short bitcoins, and future contracts also exist.

    No.

    First of all, even if there's just one bitcoin left, the system still works. Bitcoins are pretty much infinitely divisible.

    Second, you can only buy bitcoins if someone sells them to you. If you start buying all bitcoins on the market, the price will not just double but will eventually go up a thousandfold and more. Expect to pay a huge amount of money for the last few remaining bitcoins, if anyone even wants to sell them to you.

    I would like nothing better than for a government to start buying up all bitcoins. Mine will just become much more valuable. If they buy and destroy 90% of the bitcoins, the remaining 10% will still have the same total value, so each will be worth 10 times as much as before.

    Now, if they bought a huge number of coins and then threw large batches onto the market at once, sure, that could destabilise things a bit. Temporarily. But it would cost them a lot of money and would end up benefiting those who bought at ridiculously low prices.

    You obviously suck at math, then.

    If you have $2000 and can buy bitcoins at $1000:

    1. Buy 2 bitcoins (spending $2000), short one, bitcoin drops to zero: you have $1000 (gain from the short)
    2. Buy 1 bitcoin (only spending $1000), bitcoin drops to zero: you still have $1000 (saved from the start)

    How on earth did you expect to make more money by shorting something while being long on the same thing, rather than directly selling what you have?

  8. Re:Where is all of this money coming from? on Bitcoin Tops $1,000 For the First Time · · Score: 1

    Bitcoins can be subdivided pretty much indefinitely. If the US government buys an enormous amount of bitcoins, the value will just go up and prices will be quoted in microBitcoins. People who own bitcoins today would like nothing better.

    Of course, if they then threw all of those coins back onto the market, that would be a different story.

    Wikipedia lists it as a unit of energy, in fact it's the first example in the list of US units. You can calculate energy by multiplying a force with the distance along which the force has been applied (while you can indeed also calculate a torque by multiplying a force with the orthogonal distance from the center, which is a completely different thing but yields the same units).

    Nope, that's a tethered flying wind turbine. It's a mystery to me how you can harvest wind energy from something that's flying inside that very wind without any kind of tethering. Updrafts, sure, you can use those. But horizontal wind? If the drone is not tethered to the ground, the moving air is the only reference system in contact with the drone, so it can't use that to draw energy. It's exactly the same as flying in zero wind with the ground moving rapidly underneath.

  18. Re:Have you noticed? on Samsung Ordered To Pay Apple $290M In Patent Case · · Score: 1

    Do you have any examples of Apple suing people/companies for violating patents that were not already part of Apple's products? In the Samsung case, they were clearly litigating because of the way Samsung stole their design. You can argue about the validity of rounded rectangle design patents, but they were part of their actual product and Samsung only started producing them well after the introduction of the iPhone.

    Companies can and do sue for submarine patents, but to specifically name Apple in this context seems a bit of a stretch.

    And in case of Air France, all 3 pitot tubes froze over, making the flight computer completely blind

    And you think the pilot's appreciation of velocity was as precise as the pitot tubes? I strongly doubt it.

    The same type of incident with pitots freezing over had already happened several times in the past, and was on those occasions correctly handled by the crew, avoiding a crash.

    Also, not all of the automation had failed, some of it (especially aural warnings) were still working and actually misleading the pilots. And for some reason the plane kept trimming up, which was exactly what they didn't need. It's not as clear cut as it would seem from certain summaries.

  20. Re:Why put the automation in if not to use it? on Airline Pilots Rely Too Much On Automation, Says Safety Panel · · Score: 4, Informative

    NASA has actually conducted tests with special flight control software that can fly the aircraft using only differential engine power, even in some cases with an engine inoperative. It performed beautifully, much better than a human pilot could. But this is just one of the many unexpected things that can happen to an airplane (and extremely rare at that). You can't program everything into the systems, you still need basic on the spot common sense surprisingly often. As an airline pilot, I can't tell you how many times I've had to keep the plane's automation from doing something completely stupid because of some malfunction in the software.

    People often cite the statistic saying that most accidents are caused by pilot error, but those don't include the huge number of malfunctions of automation that were corrected by the pilots and therefore did NOT end up in the statistics.

  23. Re:They should upgrade the warning ... on Man In Tesla Model S Fire Explains What Happened · · Score: 2

    From the Tesla website:
    Model S is designed to allow a fast battery swap, exchanging your battery for a fully charged battery in less than half the time it takes to refill a gas tank. This offers Model S drivers another, even faster option when recharging while driving long distances.

    You can watch a demo video, doing two battery swaps in the time it takes to fill up one car's gas tank, here:

  24. If you connect a battery to a higher resistance, you get less power, not more. It's not hard to keep 1.5V if you connect it to 10 megaohm, but a lot harder if you connect it to a circuit of a few milli-ohms. The formula is voltage squared divided by resistance.

    However, the article doesn't seem to mention ohms, so I don't know where GP got that, and harvesting 0.7 Watt from a 0.1 W transmitter seems a tiny bit improbable.
