  1. Re:Photons have mass? on Physicists Clarify Exotic Force · · Score: 2, Interesting

    Photons have no rest mass. Rest mass is the magnitude or length of the energy-momentum pseudotensor. Whether it has mass depends on how you define mass. If you use a semi-classical definition of mass as that which resists motion and creates gravity, then mass is energy, which photons have. But a lot of physicists use mass to mean rest mass, which is 0 for a photon. If you try to decelerate a photon, it keeps moving at c, but it decreases in frequency. If you try to bring it to a rest, you will red-shift it into oblivion.

  2. y'all cheap bastards can be Catwoman instead on How to Become A Real-World Superhero · · Score: 1

    some black leather: I dunno, $20?
    some black thread: $1

    Or if you can't sew, you can buy a costume online.

  3. they've got it all wrong on New Model Solves Grandfather Paradox · · Score: 1

    You can go back and kill your grandfather. However, the probability of all your constituents teleporting back in time that far is much smaller than the probability of your grandfather spontaneously resurructing or you being born out of goo.

    Causality can be broken; it's just very improbable. The probability of sending a message to a faraway listener at faster than light is probably less than the probability of sending a message and random noise at the listener just by chance translating into the original message.

    Of course, this is all guesswork.

  4. No, you are clueless on Microsoft Sets Value Of Pirated Windows: $1 · · Score: 2, Insightful

    This is another country you are talking about. This is a sovereign conuntry. Your law need not apply here. You want to force them to cooperate? You can use diplomacy, or you can invade.

  5. good idea on AOL Open Sourcing Audio & Video Technology · · Score: 1

    not that I think it will happen, but that would be a great idea. They would create a free distribution that is preloaded with AOL. Casual users who only need a computer for the internet could buy a box (it wouldn't need Windows), and pop in the AOLoppix cd, and sign up for AOL internet.

  6. um, damages + PENALTY on Cuban Says RIAA Damages Should be $5 Per Month · · Score: 1

    Cuban is an idiot if he thinks that the fine should be equal to the cost of the goods copied. There exists something called penalty.

  7. hidden message detected! on Feds Fund Anti-Terrorism Search Engine · · Score: 1

    The FAA and researchers at the University at Buffalo are developing an anti-terrorism search engine that will hunt for 'hidden' information -- like how to take down an airliner -- that can be puzzled together by grabbing bits and pieces from unrelated documents. Eventually, they say, the technique can be commercialized to improve search results on more mundane matters.`"

  8. So don't do business with them on Your Hard Drive Lies to You · · Score: 1

    Of course their bottom line is more important than your data. Unless you force them to re-evaluate their bottom line by not buying their products.

  9. how about this for a fix? on Phishers Using Keystroke Loggers · · Score: 1
    automated teller or whatever asks:
    Enter your pin + 39242
    next time it asks
    Enter your pin - 23984
  10. Re:Turing award winner? on The Future of Databases · · Score: 2, Insightful

    He must not be a slashdot user then.

  11. it's more of a USA thing on Tracking Sex Offenders via GPS for Life · · Score: 1

    A lot of the culture is passed down from Christian groups like Puritans. Many people believe looking upon someone naked is sinful. You can't exactly prevent looking itself, so there are laws against nudity.

  12. that's a great advertising technique on Apple Sued over Tiger, Injunction Sought · · Score: 1

    It's probably cheaper to buy some lawyers and sue some big company than buy traditional media advertising.

  13. branch of government on Microsoft Abandons Gay Rights Bill · · Score: 1

    When did Microsoft become a branch of the government?

  14. you forgot desktop users on Kernel Changes Draw Concern · · Score: 1

    Not everyone is running a web server. The popular distros are geared towards desktop users. For this group, the OS really ought to work 'out-of-the-box'.

  15. It's not that similar when you think about it on Canadians May Face 25% Download Tariff · · Score: 1

    How does relate to a tax on online music stores and others? Maybe a tax on hard drives or the internet would be more analogous.

  16. too expensive on Quantum Wires · · Score: 1

    It won't be economically feasible to make long nanotube wires for quite a while. Tiny wires to conduct within a microchip might be more realizable.

  17. where's the changelist? on Longhorn Preview · · Score: 1

    where's the changelist?

  18. There's no such thing as "inherent" rights on Study Shows China Tightens Internet Filtering · · Score: 1

    As human beings, we create our rights through our association with society. Whether or not people have some kind of inherent right to information is irrelevant. What is relevant is that as humans we have the power to stand up against tyranny.

    It's important not to confuse this with the right to stand up against tyranny. There is nothing God-given about rights, and I believe that to make information free is the morally right thing to do, even if it is not a state right.

    My point is, if the law is wrong, and you have the power to break it, and you can avoid getting caught, then law be damned. All this talk about having the right to do something is giving law divine status.

    Of course, if the law is good and just then there are other reasons why you shouldn't break it.

  19. you don't get it on Offshored Identity Theft · · Score: 1

    It's not about right and wrong. It's about power and sovereignty.

  20. time to wear your reflective hats on Remote-Controlled Flies · · Score: 2, Funny

    This is just one step closer to state-prescribed mind control.

  21. the new license shouldn't be called GPL on GPL 3.0 to Penalize Google, Amazon? · · Score: 1

    It's fundamentally different in spirit and less free. Actually the clause in GPL which allows using future versions of GPL is a terrible clause.

  22. death makes evolution faster on Top 10 Evolutionary Adaptations · · Score: 1

    Without aging and death, the younger generation will not be able to compete with the ancient super-veterans

  23. Re:Ubuntu rocks on Hoary Hedgehog Ubuntu 5.04 Released · · Score: 1

    Much faster boot process
    Sweet. Boot time is my biggest gripe with Linux. I know many of you just don't turn off your computers, but the OS should force me to leave my personal computer on all the time. That's such a waste of resources.

  24. I doubt the program can understand content on Computer Program Makes Essay Grading Easier · · Score: 1

    It might be able to guage sentence flow and scan for keywords and patterns, but there's no way it can understand content. Frankly, the content is the most important part of the essay.

    I'm skeptical.

  25. delaying tactics on CherryOS Goes Open Source · · Score: 1

    They are just trying to buy time with the confusion so they can modify the source to be more difficult to recognize. If they open source it, it'll probably be under a restrictive license for looking only.
