  1. Re:Good stuff but short lived maybe? on Elebits and Warioware - Bad Wii and Good Wii · · Score: 2, Informative

    Vgcharts.org says that there are 1.72 and 1.33 million copies of GH1 and GH2, respectively. Assuming that no one with GH1 has GH2, that means that roughly 3% of all PS2 owners have guitars (presumably all GH owners have guitars). It doesn't matter how many guitars they have, since I'm mostly interested in the number of households that have any. There is also the problem of people buying multiple PS2s, but hopefully my double counting of GH owners will compensate for that (actually, I think it overcompensates, but that's just a guess). In any case, I hardly think that 3% is a resounding success. Guitar Hero is an amazing success, and I'm sure everyone involved made money hand over fist, but I wouldn't say that the guitar controller is anything near ubiquitous.

    The dance mat is a far more successful peripheral (and I say this in spite of the fact that I hate DDR). There are many games from multiple publishers on multiple platforms that use (essentially) the same mat. The only reason for a person to not own one at this point is the fact that they don't play dance games (it also happens to be an excellent reason, but nevermind that for now). The simple fact that GH games are generally sold with a guitar, and dance games aren't (he says without proof) should make it obvious enough which one is more successful. That said, I must add that the dance mat is probably the only peripheral I would consider "successful".

  2. Re:THEMIS on NASA to Launch Magnetic Storm Probes · · Score: 1

    I don't know how common this is, but the one time I observed the birth of a new proposal, they made a list of relevant words to facilitate the acronym-finding process. Ideally, you want the acronym to bare some relation to the phenomenon of interest, but that isn't always the case (e.g., ANARChE [Aerosol Nucleation and Real-time Characterization Experiment]). Too bad they couldn't fit hygroscopicity or sulfates in there, since that's what they were really interested in. I've also seen a lot of "acronyms" that only use letters from something like half of the words involved. It drives me nuts, but I guess it's really hard to get funded if nobody can remember what your project is called.

  3. Re:physics of railguns on Navy Gets 8-Megajoule Rail Gun Working · · Score: 1

    I'm 90% sure that if you don't have at least a basic understanding of magnetostatics, it's going to be really difficult to understand rail guns. Most important is the so-called right-hand rule. Don't feel bad making funny gestures when doing magnetics; you should see a classroom of kids taking a magnetics test. Although, if your fingers are all stretched out, maybe you aren't using the right-hand rule correctly ...

    The "boom" that comes from guns and artillery (please excuse me if I'm not using that word right) isn't from the bullets moving supersonically; it's from the gas exploding out of the barrel. If that weren't the case, silencers wouldn't work. What they do is allow the gas to expand more slowly, so it doesn't make that exploding noise. A military rail gun would certainly make more noise than a silenced rifle and less than artillery, but I can't say where in that (large) range it would be.

  4. Re:About Statistical Significance on Women "Advertise" Fertility · · Score: 1

    My (shallow) understanding is that they got their p-value assuming that each of the 42*30 guesses are independent samples, which (to me, anyway) they obviously aren't. As someone has already mentioned above, you have variation in the guessers and variation in the guessees. That is to say, supposing that you had a million guessers (or that your 42 guessers were all perfect, in which case you would only need one), then all of your variation (i.e., uncertainty) comes from the 30 women. Adding the uncertainty of imperfect guessers (i.e., a finite number of them) doesn't seem to me like it could possibly improve the situation.

    As the statistician that you are, perhaps you can tell me why the paper's interpretation is correct (I assume it must be, since it got published). Notice that if it's too painfully obvious to you, it's perfectly reasonable to tell me to go read a book on statistics. Not that I will, but I won't fault you for that answer.

  5. Re:About Statistical Significance on Women "Advertise" Fertility · · Score: 1

    You are forgetting something. The p-value tells you the likelihood that the statistics occurred by chance. I think you're confusing it with the correlation coefficient (or whatever it's called).

  6. Re:Excellent on End of the Blu-Ray / HD-DVD Format War? · · Score: 1

    The content makers are not the hardware makers. Their whole worlds are different.

    No. Sony is part of the collaboration that came up with the Blu-ray standard, they make blu-ray players, and they own a number of studios (for both music and movies). Some content makers don't do hardware (and vice-versa), but it's stupid to think that they're mutually exclusive. And the whole point of business is to make money, so if you incur more in distribution and licensing costs to distribute a single movie in both formats than you recoup in sales there's no good reason to do it. If the profits aren't there it isn't worth it.

    Obviously, if the market demands something, they'll provide it. Just keep in mind that it has to be obvious to the big studios that there is, in fact, sufficient demand for both formats to warrant such a thing. Also, you're never going to find Spiderman on HDDVD ever, regardless of how things turn out. Lastly, I wouldn't be surprised to find studios getting paid to release on one format only. They've been doing that for years with video games; I don't see why they couldn't do that in the movie industry too. Obviously you don't mind it, but I don't want to have to rely on the market boycotting Spiderman 3 on Blu-ray to be able to pick it up on HDDVD (not that I have anything that plays either format; I don't) because that simply isn't going to happen. What is going to happen is either dual-disk players will become popular, or one format will fail. Sony's already proven that there isn't room for multiple formats in this space.

    As for improvements to the formats, it's already been stated, but that's total crap. You can't improve something that's a standard because then it ceases to be standard. You'd have new HDDVD movies not playing on old HDDVD players; how's that for confusing?

  7. Re:Excellent on End of the Blu-Ray / HD-DVD Format War? · · Score: 1

    That doesn't make any sense to me. What makes you think that if there were a single movie format that companies wouldn't be competing? Having multiple formats, each with their own exclusives hinders competition because, at the hardware level, there isn't a competing platform for Spiderman or God of War. If you want it, you go Sony. If you also can't live without Gears of War, then you need to pick up an Xbox360 in addition. Incompatible formats are good for companies (vendor lock-in), bad for competition, and therefore bad for consumers. I'd rather have a single format where all the companies strive to make the best machine (or movie or game) to get my money instead of making me either choose between either having access to some subset of content or buying multiple pieces of hardware that essentially do the same thing.

  8. Re:Superfluid temperatures on 5 Strangest Materials · · Score: 3, Informative

    My recollection was that it (the HeI/HeII phase transition) was in the neighborhood of 2.2 K. Now, you can say, "that's pretty close to 5 K", but keep in mind that at 1 atm, the boiling point is just over 4 K, so 0–5 K covers all of hydrogen's interesting low-T behavior.

    I thought Zelda was *very* good, but I think the controls turned out a bit... awkward, for lack of a better word. I think they worked quite well, but it never felt really natural. Also, it's honestly time for some voice acting Zelda. All in all a fantastic game though!

    Maybe I'm retarded, but I don't remember much in the way of voice acting in Okami either. Personally, I prefer the way (at least, the way I recall) Okami did it (that is, the "talking"), but it doesn't really matter to me. I find that bad voice acting is much worse than bad text, and since there so much of both, I guess I tend to be biased against voice acting.

  10. Re:The Perfect System For A Friend To Have on Two Weeks with the Wii · · Score: 1

    Nintendo doesn't need 3rd party support to stay in business, but they certainly need it to be "successful" in the same sense that the PS1/2 were successful. 3rd party support is, afterall, why Sony is #1. So you're right in that, uniquely, Nintendo doesn't rely on 3rd party software; the fact that they're still around is a testament to that. However, I don't think that Iwata and Reggie are keen on maintaining the status quo, so I expect that they would appreciate as much support from 3rd parties as they can get.

  11. Re:Ambient noise on Does Portable Music Have to be Compressed? · · Score: 1

    $80 headphones are not better than the best loud speaker system; if you think this, you haven't heard a decent loud speaker setup. I have Beyerdynamic's top-of-the-line dynamic headphones (and I've listened to Sony's and Sennheiser's top-of-the-line as well), and they don't come close to "the best loud speaker system". They do, however sound significantly better than ~$300 speakers. A rule of thumb is about a factor of 10 difference in what you have to spend to get equivalent performance from a loud speaker setup.

    As for 3D, I think it was already mentioned (I didn't follow the link), but binaural recordings with headphones are about as good as it gets. The biggest irritance with headphones (aside from the lack of visceral bass) is that there are some recordings (particularly old ones) that try to get better separation from loudspeakers by completely separating the right and left channels. This tends to give me a headache, and the easiest way to fix it is with some kind of crossfeed (I use foobar's built-in crossfeed), although (at least with analog filters) it tends to distort the signal.

  12. Why average over all games? on Sony Console the Worst Launch Ever · · Score: 1

    They didn't even provide the important parameters. Like the standard deviation. Who cares what the average is when 80% of the titles are crap that no one wants. Why not rate the top 5 (or 25%) of the launch titles and average those? You know, the games that people might actually want. Either way, you want to know what the spread is; if they're all within 1 sigma, then it doesn't matter what the "ranking" is.

  14. Re:No component cables for the PS3? on Grading the Sixth and Seventh Console Generations · · Score: 1

    Does the PS3 have actual RCA jacks on the back of it? Because if it doesn't (and I don't think it does), then those $10 component cables will be totally useless. My understanding was that it's backwards compatible with the component cables for the PS2, which means that if you don't have them already you'll have to spend another ~$30 or so on the proprietary Playstation component cables (or cobble together your own using the connector from the composite cables that came with it, provided you know what each of the contacts is for).

    Personally, I agree with you that there isn't any reason for Sony to bundle in the component cables, but for a different reason. Assuming that I am right in thinking that the component jack is backwards compatible, the vast majority of people that want HD out of their PS3 either already have component cables or don't know the difference. Also, the fact that they use a proprietary connection on the Playstation end means that it'd be ... awkward ("expensive", I think is how Sony would characterize it, although I don't actually think it is) to include both composite and component (and I think they would be insane to not ship with composite cables).

That knocks your estimate down by an order of magnitude. So $40k. Is that really meaningful to a company as large as Gamestop? I can't imagine it would take a dude an hour to deal with all the pre-order crap, but that's still only ~$6/store. Personally, I think the reason they preorder is that it keeps you from buying at someplace else; if no one else is offering preorders, you secure all of the enthusiasts.
    2. I don't think most of the people running in there for preorders are shopping around, but I also don't think either of us has surveyed the folks so there isn't much to talk about.

My wife and I are grad students, so we're not exactly rich (although, we also don't qualify as "poor", which is to say, I don't get food stamps or anything like that). But we have enough that I can pretty much afford what I want. I've plunked down way more than $600 for what are essentially toys. So when I say that $600 is too much, it's not like I'd be starving if I bought it. If some bastard took $600 out of my figurative pocket, I'd be more-or-less fine. That doesn't mean that I want to spend $600 on random things. If it did things that I was willing to pay $600 for, then I would. End of story. As far as I'm concerned, it doesn't. And it wouldn't really matter how rich I was, because I'm already capable of making the purchase. That said, I am not surprised that there are people that find it "inexpensive". They just value what it provides more highly than I do.

  21. Re:Wii. or what's up in Japan? on Some PS3 Games to Cost $75 in Japan · · Score: 1

    In Japan, the Wii is selling for 25,000 yen, so the difference is $215. Also, though the GP's prices are right for the US, in Japan they're somewhat lower: $33 for remote and $15 for the nunchuck. "Normal" games look to be around $40, though Twilight Princess will be something like $68.

    That said, I don't really care what the price difference is in Japan, since I don't live there (do you?). For me, the difference is $272+game ([$500 - $250]*1.088 + Wii Sports), though I'm guessing that for many people it's closer to $350 (if their hearts are set on the "premium" version). How meaningful that difference is depends on the person. In particular, I don't don't care about HDTV, HDMI, DVD, Blu-ray, Web browsing, or music and video playback, so it's something of a hard sell to me. If I were interested in Blu-ray, though, it'd be a no-brainer.

    Does anybody actually know that Sony is selling these consoles at a loss, or is this all just wild speculation? So far as I know, the only company that has ever sold a console at a loss was Microsoft, and they explicitly were not interested in making money on the console, but rather spending a boatload of money to make their way into a new market.

    According to this guy, Sega lost money on the Saturn and the Dreamcast, and Nintendo lost a little money on the Gamecube in the beginning. As for the current line-up, the only things I've read were reports from financial firms that just guessed at the cost of things (which I assume is the material that everyone else is looking at), so I don't know for sure who is losing money, but I haven't seen anyone claim that, at $600, Sony is making a profit on those things.
