    How about just installing the phones in the lavatories? They are pretty soundproof.

  2. Indiana Jones Adventure at Disneyland uses this on Walk-Thru Virtual Environment · · Score: 1

  3. Don't Do It! on Laser Vision Surgery for Developers? · · Score: 2, Informative
    Any laser surgury will ruin your night vision, and if you ever want to get into astronomy, photography, or any low-light activity, you will regret it. It may even affect those late night coding sessions.

    There are reversable alternatives, such as Intacts, but they may not work with your degree of astigmatism.

  5. Nothing Unusual on UC Irvine Cracks Down on P2P · · Score: 2, Insightful
    Almost every college and university has blocked or limited P2P software from accessing the internet, simply because the bandwidth is too expensive. Here at WPI, soon after Napster became popular, internet connection speeds dropped to less than 10% of what they previously were. After blocking P2P software, bandwidth use dropped a whopping 87%.

    However, they do allow, and even encourage, the use of GnucleusLAN, which allows access on the local network. Since it is all local, we get really high transfer rates (at least 400KB/s), and it doesn't degrade network performance. Yes, the files are at least a week old (many kids get files of Kazaa when they go home for the weekend), but I've been able to get more stuff than I ever could on the outside.

    You have to remember that P2P software is very inefficient with bandwidth. As this article shows, P2P programs can generate as much as 150KB/s of downstream traffic even when you aren't downloading stuff.

    So, in conclusion, stop whining (and good luck finding any other college which allows unrestricted P2P access). Just be lucky that you have any access to internet P2P -- most college students don't anymore.

    Can someone tell me why this is news?

    And the Tungsten T has an advanced polyphonic speaker and a microphone -- ironic, eh?

  8. Re:Palm Hardware on Pictures Leaked of 3 new Palm handhelds · · Score: 1

    No, the Palm V was IDEO, the same people that did the Treo. I really think palm needs to go back to them, as they really haven't had a good design since the Palm V and Vx.

  9. Re:that last one on Pictures Leaked of 3 new Palm handhelds · · Score: 1

    Supposedly, it was taken with the built in camera on a cell phone. Considering that Palm is targeting this one at BlackBerry's new phone/blackberry device, and considering that Haldspring has pretty much abandoned Grafitti, it seems somewhat reasonable. What I don't understand is why the non-phone Tungsten-T has a speaker and mic, but the phone Tungsten-W doesn't.

  13. Re:I hope this isn't true on Slashback: Segwait, Farscape, Leg-pulling · · Score: 1

    I've heard rumors out of Manchester that DEKA has been testing a six-wheeled segway that can climb stairs (combining the Segway with Kamen's earlier invention, the iBot wheelchair). Maybe they decided to hold off on the current version until the six wheeler is available. Check out this thread for more info (and pictures).

  14. I hope this isn't true on Slashback: Segwait, Farscape, Leg-pulling · · Score: 1

    I was really looking forward to the Segway -- I hope this is just some amazon.com script that autoexpires prerelease items after some long period of time (it's been over a year now).

  15. never gonna work on Air Bags for Planetary Defense · · Score: 1

    If you deploy the airbag in space, it will just bounce off the asteroid, since it has very little mass (it would need to have low mass in order to be launched into space). The trajectory of the asteroid wouldn't be noticably affected. If you were somehow able to prevent the airbag from bouncing off (for example, deploying it on the surface of the earth), there is still no way that a mylar bag wouldn't pop and be totally useless. Therefore, the only remaining implementation is having this airbag pushed by rockets to apply thrust to the asteroid, which is what the article suggests. However, this would be no different than just planting a rocket pointing up on the surface of the asteroid. In this scenario, the airbag is useless. This guy must've failed High School physics!

  16. Re:Liquid Nitrogen for External Use Only on P4 2.80GHz Overclocked to 3.917GHz · · Score: 1

    I am now a freshman at WPI, and they told us this story at new student orientation. However, I had actutally first heard about it during the Summer of 2000 from a professor at the University of Arizona who knew Michael personally, and had recieved a copy of the email that is now on DarwinAwards.com. He read us the email while we were eating our LN2 ice cream.

  20. Re:what? on CD Copy Stopper · · Score: 1

    The battery could be charged by several passes over the photoreceptor. However, there would be quite a bit of lag as the disc recharged for the next short pulse. Maybe it is a longer lasting battery, and the user is required to run a recharge program which contintuously runs the laser over the photoreceptor for a few hours every few uses.
