  1. Re:What? on CERN Scientists Looking for the Force · · Score: 2, Insightful

    Er, photon has sufficient momentum to kick other things around. Normally, momentum is given by p = gamma * m * v (gamma = 1 for v much less than c), but for particles with m = 0, this is wrong and momentum is now given by p = E / c (where E, for photons, is given by h*f).

    Unless you are going to invoke "relativistic mass" (fewer and fewer physicists use this term—mainly because a relativistic mass is the same damned thing as relativistic energy, given the correspondence between mass and energy), photon has no mass.

    Nevertheless, my sibling posters are right, and the source of gravity (the source term in the Einstein equations, analogous to the electric charges in Maxwell's equations) is the stress-energy tensor (not simply rest mass of particles) and photons do contribute to that.

    That's called "finger memory"—probably the best way to remember a password, random, but memorable to you (your fingers, anyway).

    In fact, that's probably the best way to go with any child—it'll force them to learn proper typing habits (10 fingers on the keyboard, resting on home keys and the spacebar) early on.

    The only downside to finger memory that I can see is, if you usually type on, say, Dvorak or AZERTY, you might have a problem if it's a password you need to be able to type from more than one computer, as you will have to switch the keyboard first from QWERTY. For some of my more oft-used passwords, I just ended up developing finger memory for two different keyboards in the end.

    How about, "if you have nothing to hide, hide it anyways"? Indeed. This also helps with when you do have something to hide—if you only hide it when you have a reason to hide, then the act of hiding itself becomes a sign of guilt. But if you always hide it regardless of the reason (and the general populus does it also), then it allows due process to work as it always has: innocent until proven guilty.

    I think you misunderstand him. I quote from Why "Open Source" misses the point of Free Software:

    "For the free software movement, free software is an ethical imperative, because only free software respects the users' freedom. By contrast, the philosophy of open source considers issues in terms of how to make software "better"--in a practical sense only. It says that non-free software is a suboptimal solution. For the free software movement, however, non-free software is a social problem, and moving to free software is the solution."

    I suppose it's O.K. if you don't think freedom is the most important thing—everyone has an opinion and you have every right to disagree. But you should understand that free software has never been about making a good reliable program (although that is often a by-product)—it is about the freedom itself.

    As for not using GPLv3, I don't think rms himself would hold that against anybody. As a matter of course, GNU projects will be under GPLv3, but rms has repeatedly said, for example, in the case of Linux, the kernel, it is entirely up to the kernel developers (the strongest statement you have from him is that he hopes that they will decide to upgrade to GPLv3), and as you can see in the list of free licenses (well, some not), he never held being not copyleft against any license—it's just that when one values freedom, GPL (and admittedly, it's latest version, in FSF's opinion) does the best job of protecting that freedom for everyone (or, the most number of people).

    bandwidth is only part of the cost, servers, co-location fees, DNS fees, advertisment, server administration costs (which may be part of the hosting fee.) it all costs money, how much it costs for you to lease the fiber-optic lines isn't the sum of all costs. However, much of that cost is a simple lump sum. If you'd care to see:

    1. servers: especially if you are doing your own hosting, you buy the hardware once. And replace every once in a while as they fail. You do not have to spend more on servers as you serve more porn (presumably to "crack" more CAPTCHAs).
    2. co-location fee: I suppose there are monthly costs associated with these (and I wouldn't have a clue how much they are), but again, you do not pay more in these as you serve more porn.
    3. DNS fees: Er, are you serious? If they are doing it normally, these are about $7 per name per year. Compared to all other costs, this is pocket change, and if they are big enough to do the whole "domain tasting" thing, it's actually free (or constant cost with respect to the number of domains). Not to mention, again, that this cost does not rise as they serve more porn.
    4. ads: Given that what they are doing is probably illegal (i.e. cracking CAPTCHAs; if not illegal, it's bound to violate some ToS), I'd hope that they are smart enough not to advertise. Do you see many mafia recruitment ads on the TV?
    5. server administration costs: If they are hiring sysadmins, again, like co-location above, this will be some monthly fee, but again, the cost is constant with more porns served (except, of course, more highly paid sysadmins might be able to serve porns better, but that's going into too much detail).


    If anything, the "costs" that you listed would actually encourage them to enlarge their "business" and "make it up in volume", so to speak. The only cost that, in some way, goes up with more porn served is bandwidth usage (and even this can be made up in volume).

    Yes, if these were really small operations with huge overheads like these, they could spend well over $10 per CAPTCHA "broken" in this way. But, while we are at it, why don't we hope that wishes were horses and beggars could ride unicorns?
  18. Re:Not very on A Torrid Tale of Plagiarizing Paleontologists · · Score: 1

    There are at least three methods which supposedly guard against bad science:
    1) Peer review
    2) Replication
    3) "Scientific Method" Unfortunately, these are not the methods you think they are. In particular, as is evident in the Schön scandal, peer review is not a guard (was never designed to be) against fraud. It is more of a guard against crack-pottery (although, given that fraud is also a kind of crack-pottery, there are obviously some flaws).

    I don't know what you could possibly mean by "scientific method", as the method of "hypothesis and then experiment to verify" is the method you use during your own research, not to detect bad science. The only reasonable meaning I could attach to your mention of "scientific method" is rather close to "replication", or, better put, "repeatability".

    However, even the usual requirements of repeatability before a theory or result is widely accepted is not the perfect guard against (and no one pretends they are, in case you were misled) fraud in science.

    For one, there is a culture of assuming good faith in published results (perhaps because scientists are not as big crooks as businessmen, politicians, or religious leaders and other professions), so for cutting-edge research, like the case of Schön scandal, most people would assume that they were doing something wrong when they cannot replicate the result. And it would take anywhere between 1 to 5 years, essentially how long it would take for a group to a give an honest effort to repeat the experiment, before such fraud is caught.

    And, the truth of the matter is, repeating someone else's experiment exactly is not something you would want to do anyway. Yes, it has its place in modern science, but an exact replica of another research is, (1) boring, (2) not publishable, and probably (3) won't get grants. Most near-exact experiments are more likely to happen either as a result of two groups working in a friendly competition with each other, or as a sort of convergence (i.e. experiment itself is useful other scientific endeavors), such as production of BECs around the world.

    I guess what I am trying to say is ... there is no one familiar with the scientific fields who is under such a delusion that he would think that there are enough safeguards in system to catch deliberate frauds, like cops chasing thieves. The system is more of an honor and reputation system. At least in a vast majority of fields, there are a lot more lucrative things an unscrupulous person can do than do basic research, so basic research does not tend to attract such crooks (unlike, say, business or politics). And, if there were such a person, well, he should count on his fraud lasting more than 20, 30 years---if it does not and it is eventually caught (I'd give most frauds 10 years, since science would advance far enough to determine whether what was claimed could have actually been done), his reputation is toast; it would be grounds for revocation of his tenure, if any; and he would be unemployable in the academic world.

    These are the strongest guards against fraud, not "peer review" nor "scientific method" (whatever you meant by that).
