  1. Re:Privacy for criminals? on U.S. Sides with Record Labels Over DMCA Subpoena Powers · · Score: 2, Insightful

    Not all MP3s are illigitimately traded though. MP3 is just an encoding scheme, it does not stand for Music Piracy 3rd generation or something. It's simply sound in compressed digital form. Now if I were to record something I made, compress it into an MP3 format (personally I'd use ogg vorbis but that's a whole different ball of wax) and put it on kazaa or whatever the flavor of the month is, is that illegal?

    If I happen to decide to call my 'group' Ecstasy and I decide to do songs of elements (ie, Of Carbon, Of Tungsten, Of Amercanium, etc...) and one of the files I distribute is Ecstasy - Of Gold.mp3 sure that could possibly be construed as a trademark violation or something, but if the RIAA comes knocking at my door with a long letter containing many various permutations of 'cease and desist your DMCA violations' then what? I certanly wasn't trading anything illegal (it was MY IP and no one else had anything to do with it), but I'm sure the RIAA's lawyers could somehow manage to have the jury find me guilty.

    I'm not pro-piracy, just anti-stupidity. IMHO there are two major groups with regards to the law: those who don't break because it is the law, and those who do break it because it is the law (and then there are probably many smaller groups within the spectrum). By pursuing this matter legally and with such amount of overkill, it might show the law-abiding group that trading illegal music doesn't pay, but it doesn't do squat for the other group except cause RIAA hatred to go up a notch, and Machiavelli 101 says it's better to be feared than loved and either is preferable to being hated because when your hated, people plot your downfall (something like that).

  2. pretty wambodyne if you ask me on PDA/Radiation Detector · · Score: 2, Interesting

    It's a pretty cool way to detect radiation, but I wonder about its effectiveness. They say it's the size of a '95ish cellphone, so how close to the source would it have to be to get an effective reading? They say it measures gammas so it depends on photo-interactions (ie compton scattering, pair production, photo-electric effect...not an acutal collision like the article implies). It's most likely that compton scattering and photo-electric effect will occur (they are based on essentially the proximity of the gammas to an electron) as opposed to pair production (which requires a highly charged nucleus and how many of those can you find at 1K??)

    In any case, all of those rely on the probability that a gamma will interact which means that size does matter: the bigger the counting material (the tin) the more likely a gamma will get measured. IMHO the best radiological defense wouldn't be portable little devices (which are good for measuring personal exposure) but rather some large detectors placed in strategic locations (say wiring a metal detector with some of this tech and turn it into a metal/radiation detector?).

    All in all a pretty cool devicewhich has some limited use but I doubt it will turn out to be any major solution to discovering a dirty bomb randomly, I'd say they are much better suited to scanning suspicious items (or monitoring your own gamma exposure!).

    Valve released something like this for Hlaf Life a long time ago (I think over a year ago...maybe a year and a half by now). I don't remember the exact patch, but essentially you could log on to a server and see the map from various perspectives (1st person from any of the players, overhead view, both combined...maybe some others). It was pretty cool to see things unfold in counterstrike from a birds-eye view when good teams were facing off.

    Beyond that I think there was a Q3 mod that would do what you said...it would find where the action was taking place (based on some criteria I don't remember) and would let you sit there and watch.

  5. Re:Is this car really all that? on Review Of GM's HyWire Hydrogen Concept Car · · Score: 2

    Not necessarily. All you have to do is design a system where electricity must be removed to cause the brakes to engage. Essentailly it would be a fail safe. Here's an example of how a very simplified (very very) electronic braking system could work (IANAMECHANICALENGINEER):

    Brake is forced to engage by a spring (a really strong one). To disengage brake, an electromagnet is powered which attracts the brake and compresses the spring. If power is lost, brake engages. If (for some reason) power fails ON (ie the electromagnet gets stuck in an energized state), just put a brbeaker switch or even a fuse nearby which can be removed. This'll provide a meechanical means to interrupt power to the magnets, thus engaging the brakes.

    Again, that's a very simple example that only takes into account a power interruption and a fail 'on' scenario, and it offers very simple solutions which would probably cause the car to crash in some instances (ie brakes suddenly locking up, hit some ice, go spinning away into something)...those are problems I'll leave to people whose job it is to make sure that doesn't happen (I'm thinking maybe put a brake battery somewhere so a kind of anti-lock brake system can maintain wheel rotation in the event of a catastrophic loss-of-power failure or something).

    As for the steering, a similiar emergency thing is probably viable, but nothing will beat redundancy. If you engineer something well enough and then put in 1 or 2 redundant systems beyond that, then chances are astronomically small that everything would fail. In the past 40-50 years of nuclear powered US naval vessels there hasn't been a single vessel lost due to the reactor and reactor control systems just giving up the ghost. If Naval Reactors can do it, then you can be damn sure someone else can do it.

    Using ohms law, if you play around with the current and resistance you can get voltage to change. However, it is fairly trivial to step up AC voltage: get a transformer. That'll step up the voltage to whatever you need, then all you have to do to get DC is a simple bridge rectifier, filter that signal (a couple capacitors, inductors, and/or resistors will suffice), then slap in a zener diode (in parallel! Don't forget the series resistor!) to give a flat DC signal.

    Just a little blurb re: your "Another comment about the whole Microsoft case and antitrust laws in general. I cannot understand how these laws can be remotely construed as constitutional."...

    Way back when (turn of the centure kinda thing) the trusts/monopolies were pretty much beginning to contrtol the gov't...forcing all of their workers to vote a single way, making elected officials who they didn't like have a hard time in office (via crime, etc...making them seem impotent, essentially). So they were essentially trrampling on the rights of the people which the constitution (correct me if I'm wrong) is there to protect. Not the rights of a company to get very very rich.

    IMHO, there's a point beyond which gov't regulation is needed, or else the country would begin to fall into anarchy. A situation which it's the gov't's job to avoid.

    Ok, what EXACTLY happened at three mile island? Did anything BAD happen? No. Did anything good happen? No. What happened was the reactor operators didn't trrust the system, and let the reactor overheat, melting the fuel plates and ummmm...yeah. They melted. WOW!

    A little release of readiactive gas, a little release of radioactive water, and a public panic brought about by news people who know squat talking to other people who knew less. TMI has pretty well been cleaned up, and in fact will be torn down in 2 or 3 years (sometime in 2005 IIRC).

    The main problem w/ TMI was that the people operating the plant weren't being careful enough. That, compounded with a few design flaws, led to a situation which COULD have been bad, but was really only a 'whoops'.

  11. alphas, betas, and gammas OH MY! on Run Your Laptop On Nuclear Energy · · Score: 5, Informative

    "...chose only isotopes that emit beta particles because their energy is small enough not to penetrate skin. Radioactive material can emit beta particles, alpha particles or gamma rays--the last two of which are carry enough energy to be hazardous..."

    Really gamma rays (ie photons) are the only form of radiation we'd have to worry about. They have such low specific ionization (# of ions created (due to photointeractions in this case) per cm trraveled that they can go right through your body...ionizing stuff which shouldn't be and making you sick (or worse).

    The other two, beta (electrons or positrons) and alpha particles (essentially helium-4 w/o the electrons) have such high specific ionizations (due to their charges) that they will not penetrate past your skin. In fact, alpha particles won't even penetrate your DEAD skin! IMHO, I consider alpha particles are much safer (unless you swallow the emitter ) in that you could hold those 'batteries' in your bare hand and not have live skin be touched whereas the beta particles WOULD reach live skin.

    In any case, all of this is just probability so 'safe' is a relative term. Economically, many more nuclides beta decay (specifically beta minus decay) than anything else so that is probably the real reason: easier and cheaper to get enouogh of the right nuclide...but I applaud the efforts at trying to show the general public that at least one type of radiation isn't so bad.

    You can bet as soon as these decay-powered batteries are available I'll be the first in line to get one =)

    Doubtful...just because you pay off debts doesn't mean squat. Those countries would have to have infrastructure built for them as well. Otherwise a bad year of crops, some million starving people, and boom: regime change, attacks on more fruitful neighbors, etc...

    Investment in military tech development can yield amazing results. Case in point: nuclear power. Without the government funding big science during the manhatten project, how far could a scientist have gotten? And after we tested atomic theory using weapons, we were better able to design nuclear reactors (some better than others: US Naval reactors being near the top, reactors like Chernobyl at the bottom).

    Ultimately, IMHO, a peaceful situation is a stagnant situation. If there was complete peace on earth, I believe that people would tend to be more and more complacent with the technological level. Why bother trying to make perfect even better?

    So all of that $800 billion is not necessarily lost. This laser thingy from the article, who knows? Perhaps one day we'll use laser thingies like that as part of a mission to mars to fend off space debris from the craft? Maybe it'll save the craft from certain death coming from a big object which would set any manned extraterrestrial missions back by 100 years? Meanwhile, in the interregnum between now and the hypothetical then, if it helps people like me survive just a little bit longer in the heat of battle then I'm all for it, peace spending be damned.

    In any case, I hear canada pretty much has no military (~50,000 members last I heard) so if you're not already a canadian citizen I'm sure it would be closer to your government-spending ideals than most other 1st world countries; you might consider moving there.
