  1. Summing on Build Your Own Gauss Pistol · · Score: 1

    Gauss should've shot himself, as being the genius he was, he would have been able to do this in seconds.

    Integers from 1 to 100 is easy, as each pair makes 101

    So we have
    1 + 100 = 101
    2 + 99 = 101 ...
    10 + 91 = 101 ..
    40 + 61 = 101 ..
    50 + 51 = 101

    The result (50 * 101 = 5050) is simplicty itself.

    waits for someone to point out flaws...

  2. Send a letter to on White House Obfuscates Email · · Score: 2, Funny

    The Other Whitehouse. It's easier, and you can guarantee someone in the government will read it. ;-)

  3. Re:Silly question on The IT Market: Cyclical Downturn or New World Order? · · Score: 1

    Thats often true of outrsourcing in general not necessarily to another country. What outsourscing often does, however is transfer the skills to that country so the next wave will be making the complete product.

  4. Re:Americans have creativity on The IT Market: Cyclical Downturn or New World Order? · · Score: 1

    If you can program, the next generation will be designers. If Indians can be doctors, and half the doctors seem to be, a task as simple as software engineering will be done in their sleep.

    The better educated amongst them will be the more driven to succeed, and in the same way many migrants prosper, I see no reason why the new educated generation will not.

  5. Re:Early x86's weren't that great. on Tulip to Relaunch C64 · · Score: 1

    It's not the memory model I have any objection to, although you were right, the 8086 is a weak processor compared to the 68k, but a more even comparison is an 80286, which was (just) available at the time.

    It's the register set - the fact you each register (E) AX, BX, CX .... is dedicated for a specific purpose. Having register flexibility on sensible processors just feels so mouch more liberating.

    Drives me insane every time I program one of the bastards

  6. Why on Tulip to Relaunch C64 · · Score: 1

    Even mobile phones have more computing power than a C64.

    The best thing they could probably do is make PC related products under the Commodore name, maybe decent sound and graphics cards.

    Granted the Amiga was pretty advanced for its day, but a half decent modern PC blows it out of the water with the advantage of being upgradeable. I personally hate the fact that 80x86 processors won out over more logical contenders (680x0, Alpha), but that's life.

  7. Open Source on X Prize Race Heats Up · · Score: 1

    maybe not open source, but IIRC the Manhattan project did bring a huge number of scientists together who talked fairly freely amongst themselves. What Open Source tries to encourage is come sort of hive activity where the whole is more than the sum of the parts. If it's less, you're in trouble!

  8. Attitude control on X Prize Race Heats Up · · Score: 1

    Bear in mind however that the closest Chuck Yeager came to being killed while testing a plane was in the NF-104, and that's because of the tricky transition from attitude control by thruster to aerodynamic attitude control

    Fly by wire may take all the "excitement" out of this transition, so mere humans don't have to worry about it (unless the avionics packs in, of course)

  9. Re:Wanna fly it? on X Prize Race Heats Up · · Score: 1

    Have you ever tried a snap roll in a 747 to prove it can't be done? ;-)

    I seem to remember that one guy barrel rolled a 737 or similar (apparently it looks impressive, but is a 1G manoever) and was told not to do it again.

  10. Nice idea but on How to Jam a Worldwide Satellite TV Broadcast · · Score: 1
    Your audio channel would consume satellite power, and the company running the satellite gets very interested when the satellite is using more power than they've calculated it should. Especially if as a result the satellite goes into overload.

    Also those unused frequencies may be allocated for military purposes - pissing off an army is not a good idea....

  11. Bad History? on How to Jam a Worldwide Satellite TV Broadcast · · Score: 1

    I'd be interested to know what steps Stalin did take to rebuild the military - he seems to still have been caught with his pants down in June '41

  12. Re:how many terrorists doe it take on USS Ronald Reagan Commissioning Tomorrow · · Score: 1

    You're right generally, going after a carrier in the middle of a task force group is most likely a one way trip, and a single torpedo would be unlikely to sink a carrier - but that's why subs have more than one torpedo tube. If you have a free shot, you're not going to fire one, you're going to launch a salvo of 4-6 at a carrier sized target, and if my sub had rear tubes, they'd be launching too.

    If I was good enough to get to the middle of the group, and lucky enough to get out, I'd want to be able to boast I'd sunk the first carrier for 50 years, not just dinged the paintwork.

  13. Just goes to show on SETI Gains Respect, NASA Funding · · Score: 5, Funny

    That putting that trojan in the screensaver that lobbies congressmen was a good idea.....

  14. Forget the X-Prize on Armadillo Aero One Step Closer To Space · · Score: 1

    Carmacks going for the best roller coaster award!

  15. Why bother on Teach An Old Athlon New Tricks · · Score: 1

    So you spend about $250 on a processor and refuse to spend $50 on a motherboard to support it?

    Weird...

    Actually I've given upstaying at the absolute leading edge of the curve - even my games machines run fast enough with Athlon XP1800s in, there's little point in spending money for the extra kick.

  16. Opinion: to fragmented at the moment on Learning Reverse Engineering · · Score: 1

    I did like this link, as in introduction into reverse engineering I feel it could become a helpful guide. But I feel that it's style is substantially wrong to achieve its ambition of becoming a book; the document style feels far too fragmented, chapters and even individual sections should be longer, perhaps detailing how to use the various programs mentioned. Perhaps an example program to be reverse engineered on Windows and Linux should be included, and output of the reverse engineering tools on that program included at various points through the book.

  17. Re:We read to stay awake, not because of insomnia on A Game of Thrones · · Score: 2, Insightful

    I have a Maths/Computing degree, and also tend to read extensively in the field of Law and Politics, but the fact is that there is nothing like a fantasy novel to help the mind freewheel and relax. It lets the imagination roam free, whereas reading a treatise on any of the subjects you've mentioned forces the mind to concentrate on the subject in hand.

  18. Book delay on A Game of Thrones · · Score: 1

    ..is probably because Mr Martin is having to devote increasing amounts of time spending his royalties from his sales of this series and less time writing!

  19. If only you hadn't posted anonymously on A Game of Thrones · · Score: 1

    +1 funny

  20. Re:J.V. Jones on A Game of Thrones · · Score: 1

    JV Jones books seem to lack cohesiveness and that "je ne sais quoi" that makes a page turner. With Martin, you care what happens to the characters and even like the bad guys.

    Having said that "The Barbed Coil" was a good idea, and well worth a read.

  22. Home Networking on Building A (Serious) Home Network From Scratch · · Score: 5, Interesting

    I did mine (a small 3 bedroomed detached house in England) all by myself.

    I was fortunate in the fact my walls are of plasterboard construction so I had no problems running cable down them, except between floors. I put a switch and a wireless router in the attic.

    What did I learn?
    a) If doing it again I would use some conduit pipe to make rewiring easier. However I did put 4 CAT5 ports in each room, which is enough for any small house!

    b) buy a big roll of cable and make your own cables - its much cheaper that way.

    c) Plan and check before you knock holes in walls

    d) I'm a good network installer but a terrible plasterer, put any holes in walls where they'll be most hidden

  23. Improvements: better bangs per buck on Flight Simulator 2002 With 13 Monitors And 9 PCs · · Score: 1

    I think he could have got a better system at a similar cost by spending more on video and less on CPU systems. 3 or 4 projectors or lcd/plasma screens would have given him a similar viewing angle with less joints.
    He could've had
    1) Front
    2) Left
    3) Right
    4) Front down (for landing)
    Another idea (not sure how good it is) would be to use those Matrox multi-head video cards or similar.

    Also what I want to know is why he doesn't have a KVM switch to avoid the need for 9 keyboards and mice?

  24. US Passport holders on False Positives, Few Matches Plague 'No-Fly' List · · Score: 1

    Hmm, if US passport holders weren't allowed on aircraft Afghanistan and Iraq wouldn't have had the crap bombed out of them. Banning them from cars would stop drive by shootings, and an American in a library is a rare enough event not to legislate against it.

    Tattoos: a great idea, but to avoid excessive pain for law abiding members of the community, tattoos should only be applied to people who aren't allowed to do something.
