  1. Re:Power per Kilogram? on New Photovoltaics Made with Titanium Foil · · Score: 1

    Their advantage, and sales, are going to come from their power to weight ratio, so that is what they highlight. They quote a 15% efficiency, which seems to imply an areal power density about half that of high cost silicon cells, or equal to moderate cost cells.

  2. Re:IPv6 Not Enough? on The Next Net · · Score: 1

    I don't know how fat your ass is, but an average ass has around 10^26 atoms. So it would take around a trillion asses worth of atoms to have IPv6 fail to be able to address each of them.

    D-He3 requires higher temperatures than D-T, and produces very few neutrons.

  4. Re:Space elevator? on NASA Unveils Centennial Challenges · · Score: 1

    Helium-3 is harder to fuse than the D-T reactions we are currently trying to achieve. He-3 is a much clearer reactions (few neutrons) if you can get it to work, and it's easier to extract power from charged particles than neutrons.

    There is actually very little He-3 on the moon, it is just that there is even less most other places. Extracting enough to run power stations on would be very difficult.

  5. Re:"We could lose all our intellectual property" on GPL Violators On The Prowl · · Score: 2, Informative

    This probably can't happen. Usually companies are only asked to stop the violation, meaning the penalty is only having to go back and redo the development the way it should have been done in the first place.

    Damages are also a slight possibility, but the amount is hard to establish for GPL violations unless they are one of those few dual license cases, where the software is also offered for sale under a commercial license.

    I suppose some court in the future COULD impose punitive damages that include loss of a company's copyright, but it seems unlikely, and would probably be reversed on appeal.

    IANAL

    Similarly, I want our politicians to feel the complexity of our tax code more personally. I propose that each Congress critter have to fill out his personal federal tax forms with no help.

  9. Re:They just can't let it die, can they? on Senators Clinton and Kerry Submit Open Voting Bill · · Score: 2, Insightful

    "...source code available for inspection upon request to any citizen"

    This sounds like it is going to give the appearance of voter verification of the software, without doing so in substance. I can just see me sitting down to a hundred thousand line listing of a voting machine program, and trying to look for backdoors or subtle miscounting tricks. The code needs to be available in machine readable form so we can add internal checks and logs and then run it in a test environment.

    The machine vendors would be protected from code theft because any rival would have to make his code public too, so the copying would be easy to see. I am sure protestations would be made that some of the source is shared with non-open source things like ATMs, but being able to fully verify the voting programs should take precedence.

    I have not looked at the text of any of the bills, so I don't know if any or all of them actually have provisions for adequate access to the source code. Since I would expect a lot of vendor resistance, I would be surprised if all of them did.

  10. Re:Profits at a pharmaceutical company on Patents and Eminent Domain · · Score: 1

    Earnings per share is not a valid measure of whether the profit is excessive; the market sets the share price based mostly on the earnings and the growth rate. For comparison, we would need to know what the return on invested capital is.

    I installed 1.0.1, then reinstalled 1.0 because I like the Textzoom extension. This hasn't been officially updated to 1.0, but extensionsmirror has a link to a version patched for 1.0 installs.

    Since it's not being maintained, I'll probably eventually have to give it up, but I won't for such a minor Firefox update.

  13. Re:Go... on Computer Cracks 5x5 Go · · Score: 1

    This is the sort of thing that makes me roll my eyes when I read that the rules of go are so simple. The issues discussed in your link seem much more difficult than equivalent chess arcana, such as ep pawn capture and the fifty move rule.

    I make no claim of being a go expert; I haven't played in many years. I was implicitly asking a not very important question: Why is the optimal result for the 5x5 board given as a 25 point win and not a 24 point win? I guess your response is that a rule change in 1958 requires the game to be played out to the end. The books I learned from (Lasker, for one) were published before that date, but I never fully understood such subtleties anyway.

  14. Re:Go... on Computer Cracks 5x5 Go · · Score: 1

    Speaking of the difficulty of telling if a group is alive or dead, there seems to be an obvious (possible) mistake in the 5x5 result.

    If black is able to control the entire board, white shouldn't move after black makes his first move in the center. This leads to a black win by 24, instead of the 25 stated in the paper.

    I believe there is a rule though about black not having to move to prove that a position is dead, so perhaps the true result is that black declares he has won before making any moves, and getting the entire 25 points on the board!

  15. Re:'gain a relative economical advantage'.. on Kyoto Protocol Comes Into Force · · Score: 1

    Switching from coal to nuclear would be roughly costless, and would go a long ways toward reducing the threat of possible climate change.

    There are interesting ideas out there for replacing petroleum in cars, but it's too soon to start a massive change. Slowly switching more of the tax burden in the USA to the gas tax might help things along.

    It is thought that the tsunami will be caused by a volcanic eruption. We usually get a lot of warning of those, so people could be put on high alert during an eruption. There would probably be additional warning before the landslide starts.
