  1. Re:Memory exists to be used on Why Use Virtual Memory In Modern Systems? · · Score: 1

    Memory exists to be used. If memory is not in use, you are wasting it. The reality is that your system will operate with higher performance if unused data is paged out of RAM to disk and the newly freed memory is used for additional disk caching.

    This does not apply any more. My (Linux) system has 8GB of RAM. That's enough to have every program I routinely use running (2.5GB), and store every other program I might use in a ramdisk (3GB), while leaving 3.5 GB available to cache data files. If it weren't for my desire to protect against random hardware failures, my computer could go weeks without accessing the hard drive.

  2. Re:What about plants? on Mad Scientist Brings Back Dead With "Deanimation" · · Score: 1

    Plants require oxygen:

    Inside chloroplasts: CO2 + H2O + sunlight => sugar
    Inside the rest of the plant: sugar + O2 => energy

    The reason plants have net oxygen production is that they also use sugar as a structural material, in the form of cellulose.

    There are living things that don't use oxygen, but they tend to be single-celled organisms such as obligate anaerobes (sugar => alcohol + carbon dioxide + energy) or chemosynthetic bacteria (funky sulpher compounds => other funky sulpher compounds + energy).

  3. Re:Near death != death on Mad Scientist Brings Back Dead With "Deanimation" · · Score: 3, Insightful

    You're either dead or you're not. It's rather binary. There's no continuum.

    The people quoting The Princess Bride above do have a point: you can't draw a line and say "everyone on this side is dead, everyone on the other side is alive". Consider bacterial endospores: no significant chemical reactions are taking place inside the spore, and by most objective measures, they're "dead". But place one in the correct environment, and it will convert to an unambiguously-alive bacterium.

    Humans are far more complicated, with even more ways to blur the boundary between "alive" and "dead".

    Current elephants are reasonably closely related to mammoths, so you should be able to use them as the base. Since mitochrondria reproduce asexually, they don't evolve very quickly, and all the other bits in a donor egg will be replaced with DNA-derived ones as the cell divides.

  7. Re:eDonkey/eMule anyone? on Researchers Decentralize BitTorrent · · Score: 4, Informative

    You seem to have some misconceptions on how BitTorrent works. Basically, when you start a torrent download, your client asks the tracker (a central server that's keeping track of things) which computers have the download in question. Your client then asks those computers for pieces of the whole download. The pieces come in random order, and it might take a while for you to get the whole file, but the strength of BitTorrent is that, by asking many computers for small pieces of the file, you're getting a share of the collective upload bandwidth of every computer that's got part of the file, rather than getting the complete upload bandwidth of a single computer. This lets the download start immediately, and means that even peers that don't have the complete download yet can help speed things up for you.

  8. Re:I've got a better idea on 1000-mph Car Planned · · Score: 1

    (2) The power to move your vehicle through air is P = (1/2)(density)(projected area)(drag coeff)(velocity^3)
    (4) At sea level, 25C, 60 MPH, A = (1 m)^2, CD = .1, you have to expend P = 1.25 KW to continue moving.

    A drag coefficient of 0.1 is outstanding for a car-shaped car, but you can streamline better than that. A teardrop-shaped car, for example, has a drag coefficient of 0.04, giving a fuel economy of 1800 miles per gallon.

  9. Re:Homebrew channel - worth it? on Nintendo Blocks Homebrew Installation · · Score: 4, Informative

    Is format shifting a form of piracy? I bought a whole ton of nintendo and super nintendo games and I still own them. If I could rip the roms from them what is wrong with using the homebrew to play those roms via an emulator?

    To the best of my knowlege, there is nothing wrong, legally or morally, with format-shifting games you already own. In order to be strictly legal, you need to do the ROM-dumping yourself rather than downloading ROM images someone else has already dumped. Running an emulator is totally legal -- this was tested in court back in the early 90s when the first console emulators came out.

  16. Re:Probably the coolest thing ever! on PC Historian Finds Puzzling Game Diskette Image · · Score: 1

    I wonder if someone managed to format a disk such that one was also able to share the data space between the different OSs?

    Not possible. The C64/1541 and the IBM-PC used different encoding schemes for putting the bits on the disk. This is why the C64 tracks needed to be marked as "bad" rather than as "in-use".

    Mac/Windows hybrid CD-ROMs can and do share data, but that's because the underlying on-disk encoding is the same for both.

    "Indium ranks 61st in abundance in the Earth's crust at approximately 0.25 ppm [2], which means it is more than three times as abundant as silver, which occurs at 0.075 ppm"

    There's apparently a lot of it on earth, but not much purified. As it becomes more useful, we can get more.

    What the article didn't mention is that indium is rather evenly distributed throughout the crust -- there are no veins or lodes of the stuff. In order to produce 25 tons of indium, you need to process 100,000,000 tons of crust.

    It's not fair, because the problem is NOT the p2p users. The problem is the oversubscribed.

    "Too much bandwidth" is defined as a sustained download of more than 4Mbps or a sustained upload of more than 700kbps, over a period of 15 minutes. That works out to ten simultaneous VoIP calls; I don't know how many video chat streams you'd need to reach it.

    On the download side of things, that corresponds to downloading one CD image every 20 minutes.

  24. Re:Yes, but does it even exist? on Leaping the Uncanny Valley · · Score: 1

    Well, point #3 could be Oblivion. The graphics are better and more detailed than Sony's graphics in EQ, but don't even come close to the insane polygon counts and animations of the FF movies.

    I'd disagree that polygon count is a good measure of the degree of realism present. Case in point: Final Fantasy 7, Final Fantasy 8, and Final Fantasy 9 all had about the same polygon count, but the character designs in 8 were far more realistic than the cartoony designs in 7 and 9 (and, in my experience, far more disturbing).

    I'm not saying that Oblivion doesn't fall between EQ2 and the FF movie for realism, but there's no objective reason to put it there. By doing so, you're making the same mistake that the defenders of the Uncanny Valley hypothesis are.

    So...why has compositing always been fairly straight forward with Linux then?

    Mostly because the much-maligned network transparency of X forced a clean separation between GUI applications and the X server, while the fact that XFree86 and the Linux kernel were developed by different groups kept the two from getting tangled up in each other.

    The typical GNU/Linux distribution is about a million times more modular than Microsoft Windows, so major changes to any one part have few undesired effects on other parts.
