  1. Re:Heli-plane? on Carter Copter Breaks Mu-1 Barrier · · Score: 1

    If the craft is falling, then the flow of air will rotate the blades. Not the softest landing, but better than nothing.

  2. Re:Uh on Knoppix 4.0 DVD - Like a Kid in a Candy Store · · Score: 2, Funny

    Aren't they ActiveX controls of DOM?

  3. Pedantry on What is the Best Firewall for Servers? · · Score: 3, Informative

    Trivium: logic, rhetoric, and grammar

    Quadrivium: arithmetic, astronomy, geometry, and music.

    So math has two of the liberal arts.

  4. Re:Planes, Trains, and Automobiles on Japan Tests New Bullet Train · · Score: 1

    But I think the idea is not to damage the train. Also, I was thinking more about the passengers. As they get it for only two seconds, it shouldn't be so bad. Hope the seats are padded!

  5. Re:Planes, Trains, and Automobiles on Japan Tests New Bullet Train · · Score: 1

    223 miles per hour is about 300 feet per second. Hence the deceleration is 300 feet per second divide by two seconds, which is 150 feet per second squared, or almost five times the acceleration due to gravity near the earth's surface.

    Yeah, a 9 is about right.

  7. Re:full quote on Windows Users Ignoring LUA Security · · Score: 1

    Perhaps both. While UNIX was not designed to be secure, it was designed to be multiuser, which helps with some security issues.

  8. Re:OS X does it this way as well on Windows Users Ignoring LUA Security · · Score: 1

    What is the difference between root and admin?

  9. Re:It's also ignored by developers on Windows Users Ignoring LUA Security · · Score: 1

    So if have an executable in /home/day/bin (day is my user account), then it isn't installed?

  10. Re:Tell that to the developers on Windows Users Ignoring LUA Security · · Score: 1

    But can an application invoke runas? Is there a Windows analog to setuid?

  11. Re:I wonder why on Windows Users Ignoring LUA Security · · Score: 1

    But Linux is more honest about the difficulty of using a computer.

  12. Re:Hahaha. on Felony Charges For H.S. Hacking · · Score: 1

    Hmm... Maybe you should make the local hard drives read-only (or require a better protected password) and have the students store stuff on a server?

    Nor the GNOME gnome!

  14. Re:Linksys on Home Networking Simplified · · Score: 1

    Which PCI cards? My Netgear FA311 works on my Pentium I in both Windows 95 and Linux. Or did you mean older that that?

  15. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    I do know what it is. I just don't kneel down before it.

  16. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    Why would you want to route packets through every city? Why not just do it for each pair of cities?

    Actually, that is not the Traveling-Salesman problem, but the shortest (fastest) path problem, which is polynomial. Even solving for every pair of nodes, it's still polynomial.

  17. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    Whose point? To get a problem of the size that you gave [10^(10^34)] would require 10^32 nodes. What kind of problem would require this? And yes, I've heard of NP Completeness.

  18. Fake emacs? on KOffice 1.4 Released · · Score: 1

    The members of the Free Software Foundation don't know this, but we've replaced their copies of GNU Emacs with Folger's Crystals Text Editor.

    Let's see if they can tell the difference. . .

  19. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    Would 1,000 cities be a small, trivial size? It would take less than 10^300 attempts.

  20. Re:What if it were written in Java? on At Long Last, NeoOffice/J 1.1 Released · · Score: 1

    Well, if there are no objective metrics in choice of language, then why shouldn't one write a kernel in Java?

    Also, even if there are no objective metrics, does that mean that there is no basis for "appropriateness" in language choice?

  21. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    But if you're only solving Travelling salesman problems of a certain size, then that isn't a concern.

  22. Re:What if it were written in Java? on At Long Last, NeoOffice/J 1.1 Released · · Score: 1

    Well, should I write this kernel in Java or C?

  23. Re:Ununhexium weapons program, eh? on The Onion in 2056 · · Score: 1

    The grandparent was thinking of "un" as "not". Hence ununhexium is not not hexium, and therefore hexium.

  24. Re:Solve the travelling salesmen problem in second on A Working Quantum Computer in 3 Years? · · Score: 1

    I don't know how fast quantum computers are, but if they are faster than classical computers, one could just bute force it.

    Also, others have pointed out that quantum computers can do better approximation of approximation problems.

    Randomness does not refer to numbers, but to the means of selection.
