    New college laptop

    I would go for the D830. A lot of universities offer discounts on dell laptops, esp. if you're going into engineering. check there first. IF you can't get a discount, then I would say it's a tossup, and I'm not exactly up to speed on all the current laptops. But I do have a fast D820 if...

    True hardware health.

    While I do not know precisely what the effect of on/off cycles is, I will say that my dad has servers in his office that have been running for 10 years basically non stop, and most work fine.

    Need Good Laptop With DVI Out

    All of the dell laptops that have a docking thing on the bottom (includes all latitudes afaik)can output dvi using a D/Port Advanced Port Replicator. You can find them cheap on ebay ($30-$40). This is good if you don't need the dvi port to be portable.

    Blood Pressure Drug Shrinks Lung Cancer Tumors In Mice

    Good to know, I just got put on an ACE Inhibitor, although I don't smoke and there's no family history of lung cancer. BTW I think this is the wrong forum given the current wording of your post. Also, do not plagiarize.

    Why aren't their headphones that use wireless network tech?

    ++ latency doesn't matter in cell phones, but with headphones its a killer. RF give syou the benefit of going straight from EM waves to the audio signal, if im not mistaken. OT: Interesting choice to delurk on.

    Laptop Keyboard Disaster

    Before you take it to a repair place or buy anything, try just putting it in there then taping it tightly together, or some other easy fix. Im trying to think of good ways....maybe rubber bands? Tape might not work because of the heat. (maybe, if it gets hot there). If there's no damage to the...

    Why is my computer restarting?

    I have almost the exact same issue. Question: does touching / hitting / knocking your case affect it at all? Doing so to mine will almost guarantee a restart, yet left untouched it will run for days. I think its either an HDD or PSU issue. HDD because my harddrives frequently don't show up /...

    Colliding Water spheres in space?

    From the looks of it, a lot of the collisions would be elastic (think pool balls), while some of them would be inelastic, ie the two spheres join together and move off as one big sphere (or stay put if they were colliding head on with the same amount of momentum). The reason for this is...

    Is refresh rate important in LCDs?

    In response to the OP: LCD refresh rate has nothing to with flickering, and really only deals with vsync and max framerates (as mentioned above). Also, to the poster that said 60Hz is good enough because LCDs dont refresh that fast anyways: you're wrong. 1/60 of a second is ~17 ms, and most...

    Can you remove 2 cells from an 8 cell laptop battery and have it function off of the remaining 6?

    You're asking for trouble. As Matthias said, these are "smart' batteries, not just some cells strung together in serial / parallel. I wouldn't expect it to function at all in such a state.

    The surprise quiz next week

    Need a bit of help with a physics problem.

    im interested in how you solved it. I should know, though :( Im thinking energy conservation using PE = mgh, but then you also have to consider the fact that the water is moving, so im not sure. Alternatively, you can work it out using pressure, assume an area for the pipe you're using...

    Infinity

    ++ to above poster. You're not listening to us at all. You're just spewing nonsense. I fail to see how the entire existence of everything we know or dont know about is invalidated by the idea that we can scale infinitely. For example: And the concept, much less theory, of infinity is...

    Infinity

    No, wrong again. While its true that a current is being drawn across for an infinite amount of team, the current is asymptotic towards zero, and the integral of current from 0 to t=infinity has a finite amount (which is equal to the energy stored in the capacitor). This is of course ignoring...

    Infinity

    No, you don't understand now, and no you couldn't :( Capacitors have a finite amount of energy they can hold (their capacitance), and it takes an infinite amount of time to put that much energy into the capacitor. Go here: http://www.ngsir.netfirms.com/englishhtm/RC_dc.htm I believe the top...

    Dell's e1705 or m1710? Buy now or wait for 8800GTX/GTS?

    Dell's e1705 or m1710? Buy now or wait for 8800GTX/GTS?

    Why not get a smaller, 14-15" laptop purely for work, and keep your desktop upgrade? Im in much the same position as you, except getting ready for college. I was gonna try to get an e1705 or another 17", but I realized that the amount of time that I would spend gaming abroad is relatively...

    Dell's e1705 or m1710? Buy now or wait for 8800GTX/GTS?

    You dont sound like the type of person that a laptop is suited for. If you are somebody who absolutely must have the latest and greatest, I would seriously reconsider dropiing $2k-3k on something that will not only start out lower clocked than a desktop, but also be quickly left behind in the...

    DVI to Component Cable

    *double take* You're completely wrong on many counts. Component is THE standard for analog HD transmission -- even up to 1080p*. You didn't hook up your component connection correct -- that, or there is a problem with your display device accepting component. *It's possible, but rare to...

    Notebook Undervolting

    Power usage for a cpu is, rougly, linearly related to frequency and quadratically related to voltage. So, an equation might look something like this P = k * f * (v^2), where k is a constant. So instead of being more efficient, as you suggested, it is, ideally, equally efficient. For example...

    NVIDIA killed off Image Sharpening for 8800's.

    I tried to follow some guides to get anime loooking better at 2x zoom using ffdshow, and failed miserably. It looked quite horrible. I don't really see why its worth it, as whatever MPC or VLC do when you hit 2x zoom works fine.
