People here keep SAYING that Latour is wrong... but not one of them -- not even one, and not you -- has even attempted to show how he is actually wrong. And until they do, I will continue to accept what appears to be very solid and legitimate math and science.
OK, here goes. Latour starts by complaining that Spencer's example fails to specify whether the cold surround is kept there by constant heat removal or by a thermostat. Of course, he then goes on to state (correctly) that it makes no difference: the heat input (from the electricity) is constant, therefore (in steady state, which is the only thing under consideration) the heat removed is the same constant regardless of any unpowered additions to the chamber. So the heat input to the wall must be equal in the one- and two-plate cases as well; in both cases its temperature is constant, and the heat removed is the same.
That heat is of course exactly the radiation from one or both plates. In the two-plate case, some of the chamber wall can see only the added plate, which I suppose everyone agrees cannot reach the same temperature as the heated plate. That portion of the wall therefore receives less radiation. As the total must be unchanged from the one-plate case, some other part of the wall must be receiving more radiation. We could suppose this to be that part of the wall that can see both plates edge-on. But, either by making the plates thin and close together, or by (as Spencer suggests to exaggerate the effect) making the added plate actually be a (partial) shroud around the heated plate, we can reduce that effect to irrelevance. Therefore the additional radiation received elsewhere on the chamber wall must come from an increased temperature of the heated plate.
On average, online gaming now consumes a staggering 407 million hours of U.S. citizens' time per year.
A whole hour and 18 minutes per person per year? That's nearly 0.0015% of the time! I don't see how the US ever gets anything done at that rate.
I don't see this a "self-incrimination" issue, after all DNA and biological samples can be taken against your will and you cannot refuse to provide it if its called for.
They can collect your DNA, but you're not required to tell them if you're a chimera. There's a difference between being the subject of an investigation against your will (which goes for your person and your effects), and being compelled to assist in it actively.
In exactly the same way, they can read your encrypted hard disk (with a warrant), and they can break your safe (with a warrant). In the latter case, they'll likely ask you to open it for them for the simple reason that you'd rather have a functional safe afterwards and they'd rather do less work (so everybody wins). However, this law differs by saying that if the cops can't break your safe, you have to help.
Of course HTTPS with any certificate whatsoever is >= HTTP. My point was that by the time ISPs are willing to add headers to your HTTP requests, they already have no problem with tampering with your connection and so might not be deterred by encryption-only HTTPS.
I like your DNS idea, as far as protecting those sites that have CA-certs goes, but it seems a bit circular to me; in order to allow my browser to stop bothering me about self-signed certificates, I go find some CA certificates (which DNSSEC must use if my ISP is to be powerless against it) and use them to double-check the self-signed ones (to make sure that the site in question is expected to present one). Why not just go for the CAs in the first place?
Unfortunately, I bet that going to HTTPS would be a benefit. What I mean by that is that the law is (probably) only strong enough in the case of encryption, and doesn't do what it needs to: unequivocally forbid tampering with traffic that isn't yours (via Comcast's RSTs or these HTTP headers or Phorm or whatever).
(Incidentally, I wonder if there's a technical solution to this that one can implement on the assumption that the ISPs are being cheap about implementing it: deliberately fragment your packets (at TCP or IP level) and keep them from identifying (the assumption: from one packet at a time) a reliable place at which to insert their headers.)
so less need to blast people in the face in order to get their attention.
But if blasting people in the face improves returns now (which it must, since advertisers keep doing it), why would it stop improving returns later? The only that that would help is if people paid enough attention even to subtle ads so that the annoyance of the blasting would outweigh the added eyeballs. Are ZIP+4s going to do that?
1) you are copying and pasting Wired's content and 2) as early as high school I was taught that if I was copying information verbatim, I had better have some sort of reference
Provide an easy-to-use "cite us" link if you like, to encourage proper citation practice. But it is the height of narrow-mindedness to assume that you know what other people want to do with text you provide them, and of arrogance to assume that you know how to do it better than they do.
Personally, I feel the most reasonable interpretation (from the standpoint of being consistent and, well, logical) would be that linking does *not* create a derivative work (for example, is Firefox a derivative of the Flash plugin, or Flash plugin a derivative of Firefox? Seems to me they are fairly independent works that use the mechanism of dynamic linking to work together.)
No one claims that Firefox is a derivative of Flash, or vice versa. What is claimed is that the resulting memory space with both objects loaded is a derivative work of each, which can only be created with the license-granted consent of the copyright holders of both objects. The trick: how strong is this argument since it applies only to the ephemeral address space created at runtime by the user and not, say, by Mozilla or Adobe?
In the obvious case of MegaCo distributes foo that always links dynamically to libgpled.so, one can argue that MegaCo is effectively creating that combined object because there is no other way that their software could be used. But IANAL, of course, and I think the real lawyers (and judges) haven't fully settled the question.
Why does the second law say no to arbitrarily concentrating energy?
Because it lets me extract useful work simply from a hot environment with no cold reservoir. I just put my box in a room and it gradually gets hotter while the room gets colder. After a while I set up a heat engine between them and extract some work from the difference. Then I can repeat the process: this time, the room can't heat the box as well, but the room is colder too, so the heat engine still works. Eventually I can get (almost -- see the 3rd law) all the heat from the room extracted as useful work, which is not allowed.
(By "arbitrarily" I meant "without reason or effort" rather than merely "without bound". Sorry for any confusion.)
Surely the fact that you are drawing all your energy from outside the system (your box) would allow for a localised loss of entropy, given the gains in entropy outside the system.
Entropy goes the other way: any normal physical system that gets hotter gains entropy, so the box would be gaining it and the room losing it. But hot systems (by definition!) gain less entropy from, say, a joule of heat than cold systems do. This is the reason for the unidirectional flow of heat: if I'm hotter than you, you lose more entropy giving up a joule than I gain from getting it, so we can't send the heat that way.
