  1. Re: A better question: on Origin of Quake3's Fast InvSqrt() · · Score: 1
    The line

    x = x*(1.5f - xhalf*x*x);
    is the "iteration". Because this code was designed to run fast and not accurate, in many parts of graphics applications "close enough" is alright, we only need to run the line once, and so leave out the actual loop. Also due to other optimizations that is not the actual line you would have in the loop, but it is where the "iteration" is.
  2. First pc on Computer Voodoo? · · Score: 1

    My first PC started dying on boot, not even geting to post. It sounded like it was working but is still seemed dead as a doorknob, not even a beep code.

    So pokeing around inside I switched the RAM slot and it worked. For a week, and again started dying on boot. So I switched the RAM slot again. Started up fine, for a week or two. Went on like this for a couple of months. Some times not even switching the RAM, just pulling an reinserting it.

    I finaly realied that it wasn't the RAM, but the power supply that had a losse connection in it. Every time I switched the RAM I would jostle the power cables. Replace the PS and every thing worked fine.

    Ok, don't know why the it can't see the second drive, but some time the "not see the drive when you first start" is because by the time the BIOS starts looking for the HD the HD hasn't finshed spinning up, and so is not in a state to tell the bios it's there.

    When you reboot, the platers are already spinning, so the HD is ready when the BIOS looks for it.

    Put an actual artical together and you too can be on /.
    I, for one, would be interested in the construction of a home built repeater

  6. Re:Key Application Overlooked on Team Confirms UCLA Tabletop Fusion · · Score: 1

    Except for the fact that most nuclear devices have to employ conventional explosives start the reaction.

    The conventional explosives are used to compress the fissile material into a supercritical mass which then undergoes nuclear fission (and then proceeds to fusion in thermonuclear bombs).

    There are also "dirty bombs" that this will detect that simply use conventional explosives to spread radioactive material (usually highly radioactive marital) over a large are as an area denial weapon.

    MOast defintly cheap. Read the trivia for Lord of War. It was cheaper to use real guns then prop guns for the stockpile.

    Admitily they weren't buying the guns, but still, they wouldn't have been buying that many props.

    Mountain Dew 'Energy' is now up here, since they bill it as an enery drink they are allowed to put caffeine in it. It's the same stuff that they have the the states. Excecpt ours has a "recomended dosage" on it. As for Code Red, It's basicly Red Mountain Dew. Actualy I liked it better then Norman, there are just no places nearby that stock it
