    First off, I'm out of the loop on the crusoe deal, so this question may be totally irrelavant...

    When you say that a large portion of the operations occur in software, are those on the instruction level, or on a lower level?

    If it is the instruction level, it would be interesting to try to improve on the instruction code that transmeta provides.

  8. Re:Removing Dither.. on Guiding Air Traffic Sans Radar With GPS · · Score: 1

    I don't *think* the dither was an encryption. It was just a way of misrepresenting the location of the satellite.

    Each satellite broadcasts a repeating signal (30second period for commerical) and based on what the current 'note' is in the signal, the current time, and the general knowledge of the satellite orbit, your gps figures out where the satellite must be.

    I *think* that the dither was just a random lenthening or shortening of a couple notes each time the song looped.

    no real encryption there. If you listen for an hour or so, you should be able to just average out the random errors.

    The military side is obviously encrypted, broadcast on two different frequencies (I think it is two songs), and the periodicity is something much longer than the comercial version. I believe it is on the order of days or weeks.

  9. Re:Possibilities for sabotage on Guiding Air Traffic Sans Radar With GPS · · Score: 1

    Each satellite has a unique "song" that is repeated every every 30 seconds--on the commericial side. The military "song" is on a different frequency and is much much longer, repeated on the order of days or weeks. There is a lot of encryption on the military side as well (naturally)

    A GPS unit knows the song for each of these satellites, and by this song, and knowing what time it is (and what timezone you are in), and knowing the general orbit of each satellite, it can figure out the distance between you and the satellite depending on what note each satellite is on.

    So I guess to fake out a gps, you'd have to know the 'song' of several of the satellites. I wonder if this would just jam the gps though...

  11. Re:GPS failure? on Guiding Air Traffic Sans Radar With GPS · · Score: 1

    Off hand I don't remember how many gps satelites there are, but I am pretty sure it is close to 30. At any given time my gps can see 6 or 7 sattelites, and that is for a cheap commerical version (e-map).

    Three sattelites will give you a reading, but atmospheric distortion and what not makes it less accurate than you might initially guess. If I can get 4 satelites that aren't inline with each other my accuracy goes to about 15 feet horizontally.

    These sattelites are continually being replaced and there are several "spares" on the ground waiting to be launched.

    My gps is usually accurate to 15 feet (horizontally), and it cost about $180. Altitude varies significantly +/- 100 feet or more.

    I think perspective is what is needed here. Lucas' audience is young children. While adults have liked many of the starwars films, that was accidental (or incidental?).

    Lucas succeeded with ep one. Kids love it. It made insane amounts of money because of kids. Sure I think starwars ep one could have been a great multi generational movie, or even just not a kids movie, but that isn't what lucas wants to do...so we just have to byte the bullet and know that crap like jar jar is gonna be in it. If we don't like it, well it doesn't matter to lucas.

  14. Re:nVidia vs. ATI on ATI's HyperZ Demystified · · Score: 1

    Dude, you totally missed the point. In all my measurements, 320x200 was the origin, not 64x48.

    I am not at work now, so I don't want to spend a lot of time on this one... but look:

    surface area of 640x480 : 307200 square_pixels
    surface area of 320x200 : 64000 square_pixels
    surface area of 64x48 : 3072 square_pixels

    distance between 64x48 and origin : 60928 square_pixels
    distance between 640x480 and origin : 243200 square_pixels

    Do you finally see it? 64x48 is closer to the origin (origin=320x200) than 640x480. I can't make it any planer than that. If you still don't get it, well, I'm sorry. Please don't feel any dumber for it, it isn't important.

    Anyway, your numbers in the same example, calling 1000x1000 the origin...

    distance between 1x1 and origin: 999,999
    distance between 1415x1415 and origin: 1,002,225
    (units in square_pixels)

    so yeah, 1000x1000 is closer to 1x1 than it is to 1415x1415.

    you chose a remarkably bad example. If your last set of numbers was 1414x1414 it would have worked.

    Actually, looking at these numbers, go ahead and feel dumber if you can.

  15. Re:nVidia vs. ATI on ATI's HyperZ Demystified · · Score: 1

    I guess if you looked just at the x ( or just at the y coordinate), the distance between 320 and 64 is 256, which is less than the distance between 320 and 640, so I am right.

    but if you look at the number of pixels:

    640x480=307200
    320x200=64000, distance from 640x480=243200
    64x48=3072, distance from 320x200=60928

    oops, damn, I am right again.

    damn, I must be wrong though, because you feel dumber for having read that.

    hmmm. normalizing?

    640x480 is built of 100 64x48 tiles.
    320x200 is built of nearly 21 64x48 tiles.

    so there are 79 64x48 tiles between 320x200 and 640x480, but only 20 tiles between 64x48 and 320x200. damn it, I am right again.

    Ah, I've got it, percent difference from 320x200.

    640x480 is 79% bigger than 320x200
    320x200 is 95% bigger than 64x48

    So am I wrong after all? I say no, therefore I am not.

    nope.

    I think it is likely enough that the logo was created on a system running 95 or nt or something. Likely enough to make that assumption.

    Granted it wasn't 64x48, but it isn't "closer" to 640x480 (not even *much* closer). It is 320x200, which, as you seem to need to have explicitly pointed out to you, is closer to 64x48 than 640x480.

    I don't know what anti-aliasing on the fly has to do with it. anti aliasing is anti aliasing. Presumably the method of anti aliasing used on the logo is superior to the method used by the cards, but maybe not. I don't know. I'll concede that using "fsaa" doesn't fit this example... I should have just said "aa."

    Perhaps if you had a cup of coffee or tea, you'd make a better argument.

    I have a geforce 2 gts 32mb. Occasionally I mess around with the fsaa settings, but in general i've found that the gain in picture quality is not worth the hit to performance.

    In ultima ix, fsaa just makes the picture seem a bit blurry. While it is true that the jaggies go away if you blur your eyes, where is the benefit in that?

    I've used fsaa on the fish screen saver from voodooextreme.com... at 640x480, fsaa makes a big difference, it gives the appearance of running at 1024x768 with a high dotpitch (0.4 maybe) monitor. The interesting thing is that the screen saver runs faster at 1024x768 w/o fsaa than 640x480 w/ fsaa. So even in this app where fsaa shows significant improvement, it is still better to just run at higher rez.

    If you want to see the real deal, the genuine benefit of fsaa, just look at the windows boot screen. Would you believe that the resolution of that logo is actually 64x48 pixels. That's right, it was originally a postage stamp. That fine job of anti aliasing alone makes the os worth the purchase price.

  24. They should do what... on Techies Saying No To College · · Score: 1

    When we are growing up, we think we know everything. As we get older, this doesn't change, but the amount we do know increases and approaches the amount we think we know. At a young age like 18 or so, it is pretty easy to make a really stupid decision that we felt was informed at the time.

    This, in my opinion, is where parents come into play. They know a heck of a lot more about life than you, and you should value their opinion. If they, after reviewing with you your options of employment vs college, fervently say that you should go to college, then maybe you should go to college. I learned a lot about life in college, I learned a lot about people in college, and I learned a lot about learning and growing mentally in college. I also learned that college was the right thing for me to do. Perhaps if you go to college, you will learn it is the wrong thing for you.
