    Until you prove that disease comes from external agents

    That was proven, and so science moved forward.

    There are plenty of diseases, such as arthritis, which do not come from external agents, but rather from your body malfunctioning on its own, and several, such as high blood pressure due to obesity, which the patient very likely caused by mistreating his own body. So no, it was not and cannot be proven, since it is untrue.

    Now, if you were to say that it is proven that some diseases come from external agents, you'd be quite correct.

    If you wanted to try and apply this to more than two bodies you'd need a formula which took account of the forces being vector quantities. Which would be several times more complex a formula in the first place...

    No you don't. Nothing stops you from calculating the force as three component vectors, aligned with the axis of the carthesian coordinate grid in the first place. Something like xforce = (x1pos - x2pos) / distance and repeat for the other two coordinate axes. Then, after calculating all the forces between each object pair this way, sum them up by coordinate axis and object to get the final component forces affecting each object.

    Very useful if you're doing computer simulation.

    You've had a great idea, but the Finnish government haven't.

    The Finnish government is a sad parody of what it once was. Once it dealt with both Nazi Germany and Soviet Russia and came up on top and turned the country from an economically abused agricultural colony (located at the arctic circle, as an icing on the cake) suffering from a civil war into a peaceful, democratic, industrial first-world country. The current version, on the other hand, falls all over itself trying to bow down to Russia, EU and the USA simultaneously while passing one bad, freedom-removing law after another. The new finnish copyright law, the so-called "Lex Karpela", is a perfect example: even the government which passed it itself admitted it doesn't know what it actually forbids or allows, but passed it anyway.

    The Finnish list is an arguably erroneous list (it contains many sites that are seem to be perfectly legal), foisted on ISPs who are supposed to "voluntarily" ensure their paying customers can't access the sites on the list.

It was perfectly obvious from the beginning that this was the true purpose of the list. If these creeps actually thought of children, they wouldn't be constantly cutting funds from education to finance rising their own pay.

    Is it just me, or does every country have at its helm the most disgusting subhuman slimemolds it manages to produce ?

  13. Re:Remember "A New Hope" on Prince, Village People to Sue The Pirate Bay · · Score: 1

    BitTorrent, as implemented today, is also relatively decentralized. No one torrent is, but BitTorrent itself is as decentralized as the Web -- anyone can throw up a tracker, or put a torrent on an existing tracker and seed.

    BitTorrent, as it exists today, isn't a network. Each torrent is in theory completely separate. As such it doesn't really make sense to talk about "BitTorrent itself", since there is no such entity, just a protocol used in numerous separate and unconnected transmissions. Each torrent fomrs its own mini-network, usually with a central server (tracker), altought trackerless torrent works pretty well too; and these mini-networks have nothing to do with each other. Consequently, BitTorrent doesn't support searching for files, since there is no network to search them from.

    Gnutella, on the other hand, is both a protocol and a network. All Gnutella clients in the world cooperate to form a single connected network for the purposes of searching for files. And the Gnutella network is completely decentralized.

    BitTorrent and Gnutella are thus fundamentally different. Gnutella is self-contained, since it supports searching the Gnutella network; you don't need any other program besides the Gnutella client to use it (not counting the OS, of course). BitTorrent, on the other hand, requires an out-of-band method of getting the torrent file in the first place; a BitTorrent client is useless on its own. In this way, BitTorrent is basically a replacement for GetRight and such programs: you click on a link in a webpage, and BitTorrent downloads the file.

    In a way this is like the difference between FTP and the Web: FTP servers are unconnected from each other, while Web servers form a greater entity, the Web itself.

    If you own a four stroke, spark ignited, internal combustion engine, you have one now. The conversion to run on hydrogen gas instead of liquid gasoline is quite trivial.

    The conversion to have the fuel tank to store hydrogen is anything but. The damn thing has a habit of oozing straight through metal, due to the small molecule size. You can't store the gas under pressure, since the gas tank in your car is not designed to hold any pressure (and in fact is open to air, since otherwise the gas wouldn't flow), and storing hydrogen as liquid requires both extremely cold temperatures and very large volume.

    Anyway, what would be really useful: a solar cell which pulls hydrogen from water (water vapor, preferably), carbon from carbon dioxide, and combines these to form hydrocarbons (oil). It would help combat global warming, mitigate the peak oil crisis, and save you a lot in fuel costs - and work with the current infrastructure with no changes needed. Heck, you could install it on all the outside surfaces of your car and have the generated fuel trickle straight to the tank. Any eggheads out there working on this already ?-)

    Black absorbs sunlight. The satellite would overheat.

    Take two blocks of metal. Paint one black and leave the other shiny. Connect the black one to the hot and the shiny one to the cold reservoir of a heat engine and send the whole thing to orbit. Do we now have a perpetual motion engine ? Remember, the universe is full of background radiation, so such an engine could still keep operating even after each and every star has burned out and the universe has suffered heat death.

    Of course what really happens is that black surfaces also radiate energy more easily than shiny ones. Consequently, in the vacuum of space where electromagnetic radiation is the only way to get rid of heat, a black object will be at the exact same temperature as a shiny one. Otherwise the laws of thermodynamics would be broken.

    On Earth, on the other hand, the atmosphere allows conduction and convection, which are independent of the color of the surface; consequently, a black object tends to get hotter in direct sunlight.

    So, in short: no, the satellite would not overheat. It wouldn't be any hotter than a shiny one.

    No, it returned as Gnutella and other fully decentralized P2P networks.

    Then again, Gnutella also uses the download mesh technology nowadays. Best features get recombined with small variations in endless new combinations, and the best combinations serve as models and inspiration for the next generation. That's evolution in action.

    Part of this license states that any changes to the kernel are to be made freely available. Unfortunately for us, this meant that the great deal of time and money we spent "touching up" Linux to work for this investment firm would now be available at no cost to our competitors.

    First: GPL control distribution, not use. You are free to modify GPL'd programs and use them internally; only if you distribute them to outsiders, either as programs or as part of a device, do you need to provide the source code to the receiver of such products.

    Second: Why on Earth did you need to modify the kernel for an "investment firm" usage ? What did you think that would accomplish, especially when you are apparently unable to even use the configuration program to enable Token Ring support ?

    Furthermore, after reviewing this GPL our lawyers advised us that any products compiled with GPL'ed tools - such as gcc - would also have to its source code released. This was simply unacceptable.
