    PRO TIP: That data is not a game. You don't have to execute everything that you download from the net. You don't have to trust every bit of data that gets in it.

    ADDITIONAL: Not all computers run Windows, and not all Windows users use flawed browsers. Wget runs nicely in Windows, you can use it to download from places you don't trust, it won't get owned.

    NOTICE: Verify your computer. By the amount of knowledge you displayed on your post, it may well be spewing spam. Then remove yourself from /. while you can read a book or two on how computers work, practice a little, end then came back here.

    It took a while to convince myself that this site is serious. Arguing that relativity is a theory promoted by liberals!? But it is serious.

    Ok, getting over the hilarity of it, besides bible references and displays of misunderstanding about, some of those issues are quite real. But then, I keep reading just to find that:

    "Relativity breaks down if a solenoid is traveling at or near the speed of light."

    No shit! Now I can't stop laughing again... (By the way, that "near" gets there because of a misunderstanding, the reference was arguing about exactly the speed of ight.)

    You mean that, before the policeman took a while showing the spray can to the people, and spayed them on the eyes, without any display of violence from their part, something important happened that is not displayed on the video?

    Would you care to tell what is that important part of the truth that isn't represented on the video? I mean, how can the policeman be threatened if during the entire video there wasn't a single threatening movement from the students?

    "First, on the Linux vs Minix piece - Minix wasn't ready for any use at all or at least so it was perceived."

    Minix was once way more mature and more functional than Linux. But then, while Linus included everything that made Linux more functional on it, Taneunbaum refused to increase the complexity of Minix. It's his choice. No problem with that... But then, he can't come and complain that the software he worked hard to keep small didn't grow.

    BSD x Linux was also a matter of being easy for someone to put code into. BSD wasn't that hard to contribute too, but Linux was easier, so people wrote drivers for Linux.

    There is a lesson here: "People, if you ever do a fission based space craft, plase make it out of slow breeders, and recycle the nuclear waste." But I guess anybody planning to create an interestelar ship powered by fission would think about that. But at least one thing is better, in space it is easy to throw aray the unwanted radioactive contamination.

    Anyway, I'll wait a fusion powered one. Thanks.

  14. Re:Linux user here. on 2-Year Study Shows Mac Users Downloading More Open Source Software · · Score: 2

    I'd add a me to here. In fact, I used to download things from Sourceforge, mainly because the version available at my distro was old or had a version dependent bug. I don't do that anymore, in part because sourceforge stopped working as well as it used to (I can't even login again, try using a forum or bugtracking) and because Debian started to correct bugs faster than the packages available at Sourceforge.

    Not that the data of the article is much relevant. It is composed of only two years (came-on, Sourceforge is there for a decade now), and most of the downloads are for unknown operating systems. Also, the trend on Linux isn't a trend at all, it is composed of 4 months with a lot of downloads followed by several months with less downloads, out of that change there is no visible trend (on other OSs there is no sudden change, they are just noise with a small signal added to it). It could be that something interesting happened by 2010-2 to 2010-5.

  15. Re:It's a mystery? on Working On Man Made Lightning · · Score: 1

    The bulk of the current pass through the shortest path because the elctrical field there is strong, and you need strong fields to get ionization. After some ionization, there is very little resistence, so the current passes there. Stronger field = more ionization = less resistence = more current (and current negatively feeds that cycle, so the lightining stops). You can't do calculations with constant resistivity when the resistivity is changing by several orders of magnitude.

    At least, that is what theory says. But the theory also says that you need a much highter field...

  17. Re:It's getting interesting on OPERA Group Repeats Faster-Than-Light Neutrino Results · · Score: 1

    Yeah, as theory goes, faster than light neutrinos should radiate particles and anti-particles untill their energy is reduced. As theory goes there shouldn't be any faster than light particle either.

    What we have here is data, and if your theory disagrees with it, your theory is wrong. It is not proof of FTL neutrinos, mind you, but you can't just wave some theory and make people not belive their data, you must explain it.

  18. Re:Try, try again... on OPERA Group Repeats Faster-Than-Light Neutrino Results · · Score: 1

    Whatever there is on the Feynman Diagrams all through the path, if the neutrinos get there in less time than light would take on vaccum, they are travelling faster than light. It doesn't really matter what they turn into in the path, what virtual particles are there, or anything else.

    And if particles moving faster than light will let you send the lottery numbers back to you at the past (or make a nondeterministic computer), faster than light neutrinos will let you send the lottery numbers back to you at the past. It doesn't matter how they are created, what they turn into in the path or anything else.

  19. Re:More tests please. on OPERA Group Repeats Faster-Than-Light Neutrino Results · · Score: 1

    Besides the magnitude of the drift, they just have to synchronize the clocks at the neutrino emissor, and move the one of the detector. That way the neutrinos will seem to get later, not earlier.

    Ok, several stuff there.

    " (1) Hadn't there been something about the relativistic effects of the GPS satellites messing with the data?"
    (2) Hadn't they just swapped out their differentiators, possibly doing the calculations at the point of impact, instead of 20' up the cable, at the cable mount?"

    Unlikely (but way more likely than FTL neutrinos). They check that stuff a lot, they know how to do the math... But they are still humans, so there can be a problem somewhere. Nobody was able to find it up to now, people are still trying.

    "2nd Thermo is a mathematical law"

    It is a mathematical consequence of some models of the universe. Other models don't bring it as a consequence. Remember, we don't know how the universe behaves, we just have clues.

    "To put it shortly, if you can do FTL particles, then you can send information back in time."

    I was corrected recently here on /. while saying that. Ends up that you can't keep current physics at all, so any prediction based on current physics (and yours is based on Relativity and Maxell laws) is not reliable.

    "Moreover, sending information back in time itself violates the 2nd law of thermo."

    Can you prove it? I'm trying to for a time, but it seems that it doesn't follow from the postulate of paradox-free time travel.
