  1. Is the math entirely wrong? on The Fallacy of Hard Tests · · Score: 1
    Is the math in this article entirely wrong, or am I just crazy??

    For True-False exams for example, the number subtracted would most likely be (Number Wrong ÷ 2). Let's see how that would work out, for the sample case above. You, answering two questions correctly and guessing at 98 would be likely, on the average, to get 49 wrong, and so have a final score of 2 + 49 - (49 ÷ 2), or 75.5, while I, again on the average. answering only 1 correctly and guessing at 97, would get a final score of 1 + (97 ÷ 2) - ((97 ÷ 2) ÷ 2)), which comes out to be 25.25. Here there is a substantial difference between our scores, closer to the two-fold difference in our actual knowledge.
    2 + 49 - (49 / 2) is equal to 26.5, NOT 75.5 . . . he added it in one case and not in the other. So the actual scores that should be compared are 26.5 to 25.25. The disparity he saw was entirely from a lack of capability at arithmetic. And in all his examples, the numbers are so close not because of a lack of quality in the testing methods, but because his hypotheticals are so extreme (someone who only knows the answer to 2 questions out of 100 is ridiculous). That said, subtracting for wrong answers is still the most accurate way to grade, but not based on the crap that this guy was talking about.
  2. Re: The QWERTY Rumor on New Standard Keyboard · · Score: 1

    you're simply wrong. the dvorak keyboard was designed to have as much alternating hand keystrokes as possible. just putting the vowels on the left side probably does it more than qwerty, but the rest of the keyboard was designed with that in mind as well. you're simply wrong. if you don't believe me, copy some text into http://www.acm.vt.edu/~jmaxwell/dvorak/comparePage .html and see the results.

    oh, and by the way, i typed this in dvorak.

  3. Re:Egg Grading on Intel Plans CPU Naming Change · · Score: 1

    You're pretty close, as I understand it. Your typewriter analogy is pretty funny though, since a typewriter key might be off by a milimeter or so, while if the fab's "key," were off by the same amount, nothing would work at all. They "miss" by nanometers or less.

    The way they get the sizes is exactly as you describe. They basically take the big wafer (it's a cylinder wider than what you said; by now i think they're at like a foot and a half or so and getting bigger by the day) and cut it up after they make the chips.

    Then they take the chips, one by one, and put em in the little tester machine thingy. They try it at 2 GHz, then 2.1, then 2.2, etc. Once it doesn't work consistently, say it breaks at 2.4, they toss it in the 2.3 bucket. The next one, from the same wafer, might be tossed in the 2.2 bucket. The next one might never work because of an imperfection in the wafer and it gets thrown in the trash.

    Kinda funny how the final "GHz" rating is come by.

  4. Re:It's awesome and all... on US Government Upgrades RAM · · Score: 1

    What everyone else said in response is true, but additionally, when you consider how much more expensive RAM (whatever it is that they purchased) is than magnetic disks, and how much they've spent on the RAM, I'm sure they'd barely notice the expenditure on enough disk space to back all that up. But, if the information is actually some sort of flash or whatever (though I'm not certain that it is, since regular SDRAM is a "solid state" device), the point could be moot. (I'm of the opinion that it's not flash, but whatever).

  5. Re:Absolute must have on Reviews for Digital Camcorders? · · Score: 2, Insightful

    I don't know if I agree with all of that. If you want to make high quality cinematic motion pictures, fixed focal length cameras are likely a pretty good choice. On the other hand, this guy may very well need flexibility not available with fixed focal length cameras. If flexibility is his metric, then maybe zoom lenses are a better choice.

    For all we know, he may want to be able to videotape his friends doing funny stuff at his house but also be able to tape his kids soccer game and have his kid show up as more than 12 pixels.

    Granted, he probably doesn't need a zoom lens comparable to professional cameras used on tv and in movies, but being able to zoom is pretty important for most consumers/prosumers, in my opinion.

    That said, I know far too little about the subject to make suggestions as to which exact models he has. But I don't think he should disregard zooming as a metric (though the grandparent is right in saying that digital zoom is worthless and should be disgregarded, as digital zooming can be done (likely better) afterwards and merely throws away data).

  6. Parent is wrong on Breaking the Gigapixel Barrier · · Score: 1
    I'm surprised someone modded you up, as you are definitely wrong about this.

    A 4.3 megapixel camera contains 4.3 x 10^6 pixels. That number does NOT refer to "pixels per square inch." The actual cmos (or ccd) sensor in a 4.3 megapixel camera is smaller than a square inch, much smaller.

    The photos were stitched together side by side. That means that the final photo has 6 megapixels per shot times 196 shots. Which equals over a gigapixel.

    Your concept of resolution is incorrect. Resolution in this sense just refers to the number of pixels; there is no distance scale involved. Those pixels can map to a sensor that was a foot by a foot, or an inch by an inch, or whatever. They can also map to a picture being taken of a one centimeter by one centimeter microchip, or a light year by light year section of the sky.

    That's why the picture is indeed a gigapixel. (Or so it supposedly is, I guess. I haven't actually downloaded it yet due to the slashdot effect)

    It sounds like you need to play a song to start the download, but then once it's started, it sounds like you can then stop that song from playing. You need to play it to make that connection, but once it's started downloading, I would think you could then start another song playing and then it too will appear in the list of songs you can download. Correct me if I'm wrong, but that's what it sounds like.

  8. it's not going "off the air" on FCC Adopts Broadcast Flag Scheme · · Score: 1

    Dude, it's not going "off the air." It's going digital. Unless I'm missing something, it seems you're wrong. Network TV broadcasting will still exist. It will just be digital, so people will have to get a new TV. No, it won't be as seamless as the black/white to color switch, but it doesn't have to be apocolyptic.

    If I'm missing something let me know; I just thought I'd say this.

  9. Re:how is this an issue on Court Upholds FCC's 2007 Deadline For Digital TV · · Score: 2, Interesting

    This is an issue because it forces the electronics industry to be the "chicken" and pay a kind of "early adopter" cost associated with switching to digital broadcasting.

    This way, they all have to make digital-capable sets. Then the broadcasters will have less of a problem switching to digital; right now they complain that there are not enough people who will receive it to justify spending the money on the switch. Then once there are digital broadcasts, the electronics company will have even more of a reason to finish the switch, and so on. Getting the ball rolling is the hard part, and that's what this law does.

    So both sides will start going to digital, and everything will be happy. Except for the broadcast flag issue, and pvr issues, and a bunch more issues that I'm sure exist.

  10. Re:How complicated is Chess? on Man Vs Machine In Chess - Who Is Winning? · · Score: 1

    Others have said it, but I'll say part of it again: many of the possible permutations can't (or won't) happen, so we won't need all 10^150.

    Also, there's the fact that chess _is_ a "solvable" game. There is (though we may never know it) a "perfect" way to play. If the computer starts from the beginning and plays perfectly, there are definitely a LOT of states it could get to, depending on what its opponent does. But, the number of states is only a fraction of the total possible game states.

    That's basically my point: there are more states possible than we can keep track of, but there is still the possibility of playing "perfectly."

    Stop reading now if you don't want a lot of drivel.

    There's a counting game I just thought of. Two players, each turn you can count 1 or 2 numbers. The person who says the number 7 wins. A sequence could be:
    1-23-45-6-7 and Player one wins.
    It turns out that if on the first turn, you just say "1," then after that, you just say the opposite of Player 2 (he says two numbers, you say one, and vice versa). So:
    1-23-4-56-7
    1-2-34-5-67
    and so on. You can always win. Now let's say the game goes up to (3x10^99999999) + 1. That's way more possibilities than we can remember. But, we could still play perfectly, since we know this magic rule.

    Not a perfect analogy, I realize. There is no magic rule in chess that's quite so simple. But, my point still stands: a computer can learn to play perfectly without having a lookup table with 10^150 entries.

    Like usual, I'm probably wrong, so correct anything you want.

  11. Re:major problem.. on Spam And Alston - From Luddite To Pin-Up? · · Score: 3, Interesting

    Non-profit groups are exempt.

    Sorry, but I don't like spammers that are trying to save my soul any more than spammers who want to sell me placebos to increase my sexual prowess.

    That may be true, but what percentage of the spam you receive is trying to save your soul? If your inbox looks anything like mine, it's full of low-interest loan offers, porn offers, and penile enlargement stuff. If that stuff can be eradicated with this bill, then I'd be all for it. I, for one, don't get much non-profit spam at all, if any. But I don't know about everyone else.

    The notion (that another reply offered) that penile enlargement companies will spawn non-profits just to do the spamming for them seems awfully far-fetched to me. I was under the impression that non-profits had to meet certain criteria or something of that sort. I highly doubt an organization would be allowed to keep non-profit status if it were sending out millions of porn ads a day.

    Of course, as usual, this is all just my opinion, and if the past is any indicator, it's highly likely that I'm wrong.

  12. Re:Nonsense on Music Industry Compared to Movie Industry · · Score: 3, Flamebait

    While I doubt this will get read by anyone, since the article was posted a while ago, I'll say it anyways:

    I was just thinking about the argument you guys make: buy used cd's; the RIAA gets nothing, you're happy etc. but I just realized that there's definitely a flaw to that logic.

    Every time you buy a used CD, you are voting with your wallet. You're telling the used CD store that yes, people want used CD's. They will pay more for them than the store has to pay to get them. It's profitable to buy and sell used CD's.

    By buying the CD, you are sending that message. Now, think about what would happen if you didn't buy that used CD. It'd sit on the shelf for a while. The store would think to itself: maybe it's not a good idea to keep doing this used CD thing. So it would stop buying them.

    Then, the people who sell the CD's to the store (who are, incidentally, also the people who buy cd's new) would not be able to do so anymore. As a result, they'd be less inclined to buy new cd's.

    By purchasing used CD's, you help keep the CD market alive. Not a huge effect by yourself, but everyone together makes a difference.

    Anyways, I haven't thought this through all the way; it just came to me now. I may have made a couple mistakes myself. But it seems that buying used CD's may not be as harmless as everyone makes it out to be.

    If you are going to lump all women over the age of 18 together and compare that to middle school and high school boys, I guess you could say that the numbers add up in favor of the disproportionately large population.

    I think it's still a noteworthy statistic, regarless of the fact that it may be skewed. I'd be willing to bet that the percentage that are women is much higher than 10 years ago (or 5 years ago, whatever), and the percentage that are boys is probably less. I don't have the statistics, and I don't know if anyone else does either (did they do those statistics then?), but I think we all know that there weren't many women playing super mario bros when it first came out, but the "cool" boys (and the uncool boys for that matter) in the second grade sure did.

  14. The answer is yes on Videogames Attract More Women Than Boys? · · Score: 5, Insightful
    The study found that 26 percent of game players are women 18 or older, while at 38 percent are men 18 and up.

    Who writes this stuff? Do people read more than just the headlines anymore?

    I believe the headline compares "women" and "boys." Not "women" and "men." It is a long believed notion that videogame players are "little boys playing mario in the basement." The point is that times have changed. No longer are girls given "Barbie sidescroller junk" games. The sims and more are starting to appeal to them.

    In addition, the main group of gamers is getting older. People who were teens or so when Nintendo, Atari, Commodore came out are grown up now. And you can look at the way game focuses have changed as a result (the successful platforms (PS2 and XBox) are the ones catering to older guys: more violence, mayhem, etc). On the other hand, consoles like Nintendo are pointed towards the same audience (and this is probably where women are playing most). I guess I've gone off on a tangent though, so I'll stop now. My point is that, to answer your question, yes, people read the headlines.

    This was actually linked in an above comment, and in the slashdot article linked to in the story heading but Wired has a really good article about just this topic.

    The basic idea is that (unfortunatly) there are just a few players out there, but (fortunately) they're big players. They intend to revolutionize computing the same way the mosfet did, etc. I don't know all the science and stuff, but basically they're getting able to make high quality, super good, diamonds synthetically, fairly reliably, and fairly cheap.

    Most importantly, they're able to make the diamonds without DeBeers. I don't remember which companies are focusing on which side of things (jewelry vs. semiconductors), but I think the moral of the story is that progress is being made, and the diamond semiconductor revolution does NOT have to include DeBeers, which is a good thing for all involved.

    I think I disagree a little. Some users might have a problem ever typing a password or something, but I think most people are pretty reasonable. I know that when I started using a Linux desktop this summer, I didn't mind typing in the root password to change stuff around that would affect everyone. In fact, I kind of liked it since I knew I could play around as much as I wanted: if I didn't type in the root password, I couldn't affect anyone else.

    On the other hand, I'm at this site, so I'm probably not your average computer user. And, Linux does have some stuff wrong (in my opinion). Changing screen resolution . . . adding printers . . . some of that stuff I'd kinda like to do without a password. But gnome has that nice little key thingy that stays around; you can play around for a while, and remove it when you're done. MUCH better than logging on as a regular user, and having to logoff/logon as administrator to install a program or whatnot.

    true, it is given away for free. on the other hand, internet explorer was "given away for free" (bundled with windows) a while ago, too. and the department of justice definitely did not allow them to "do whatever they want with it." they have a monopoly on operating systems. including a proprietary instant messaging client that uses a closed standard can be seen as an abuse of their monopoly in the OS market, especially since they get revenue from the ads and stuff.
