  1. Re:Broadband over power lines was never a good ide on Still Little To Do About a Bad ISP · · Score: 1

    Big ditto on that. I kept donating money to the ARRL's Spectrum Defense fund.

  2. Re:Of course on Still Little To Do About a Bad ISP · · Score: 1

    What if... let's just say.. your local government installed FTTH for an open network that allowed for any service provider to hook in and compete equally?

    Yeah, seriously. I was waiting for someone to mention this. Why aren't inkjets banned?

  11. not much to see here, move along. on Some Early Adopters Stung By Ubuntu's Karmic Koala · · Score: 1

    9.10 with Nvidia 190.42 works great. Took a bit of work at first to get right moving from 180 as things kinda became a mess. Had to add my users to the video group manually and fix the start-up script. frames are up to 12K from 5K with glxgears. pulseaudio was a problem as the SDL lib for it was not installed. I had to get rid of the old ALSA one and put in the pulse one along with adding my users to the pulse-audio group.

    That's about it.. all minor issues to me except for the usual learning curve which is a bit steep to find and resolve these things, but it's the price we pay.

  13. Re:At the Risk of Sounding Like an Apologist on Poor Design Choices In the Star Wars Universe · · Score: 2, Insightful

    Agreed, but one also looks to Science Fiction where Science, though not predominant to the story, serves as somewhat accurate glimpses into the future.. But GL gets away from that right in the beginning of the movie with "A long time ago, in a galaxy far far away"

    If one is looking to Science Fiction for the Science aspect, there are better ways to find it. Through books for example.

  18. Re:Who cares about HAM radio on Mixed Conclusions About Powerline Networking vs. Ham Radio · · Score: 4, Insightful

    Wake up. BPL is a crappy technology. It guarantees improper radiation because the power lines aren't shielded at the physical layer. Kill BPL now and demand what we all want: Fiber Optic.

  19. Re:Keep the HAM on Mixed Conclusions About Powerline Networking vs. Ham Radio · · Score: 1

    Sure, use either Coax or Fiber Optic lines for the data.. Wasn't that an easy fix?

  20. The issue is simple on Mixed Conclusions About Powerline Networking vs. Ham Radio · · Score: 5, Insightful

    Power lines were never meant to carry RF energy. When they are, they radiate. Cable TV doesn't radiate. It doesn't radiate because it uses a proper transmission medium (Coax). If the power line folks want to distribute DATA, they should string the poles with fiber optic. Better yet, we the people should string it, and sell access to the content providers.. ala municipal fiber networks. They can work folks!

  21. Where would you go? on RadioShack To Rebrand As "The Shack"? · · Score: 1

    Easy, Fry's Electronics. They are the better Radio Shack. They are what Radio Shack should have grown to. You're lucky if your local RadShack even has solder these days. A 220uf/25V cap or a 2N2222?... NEVER! They lost my electronic hobbyist business years ago. I will never step into their stores ever again... unless I want skins for my Nokia. lame lame lame.. I hope they do rebrand! That's the sign of a sinking ship. Let it sink.

  23. Re:library of congress on How Heavy Is a Petabyte? · · Score: 1

    According to local folklore at the time when I attended to RIT in Rochester, NY., the builders of the library didn't take into account the weight of the books when designing the foundation which is why the building is sinking into the swamp it was built on.

    We could expound on your idea and look at the weight of an electron as it clocks through a CPU and find out what a bit really weighs(?)

    Electrical current is the amount of electrons passed over time (coulombs per second). If we assume a pull-up resistor is 10KOhms and the data is clocking at 500 megahertz running on a 3.3v supply, we'd get:
    3.3 V / 10,000 ohms = 330 micro coulombs per second (ampere)
    330 uA / 500,000,000 = 660e-15 coulombs per bit
    1 coulomb = 6.241506e18 electrons

    Therefore, in this example, electrons per bit is:
    660e-15 C/b * 6.022e23 electrons per Coulomb = 397.452e9 electrons per bit
    one electron weighs 9.11e-31 kg, therefore:
    397.452e9 electrons per bit * 9.11e-31 kg * 8 bits per byte = 2.896630176e-18 kg per byte
    1.0E+15 (peta) * 2.896630176e-18 kg per byte = 2.89 grams

    One petabyte weighs 2.89 grams worth of electrons assuming all values are ones. The weight of the library is the important part in this case.
