    There wasn't good data on when it was coming by. I was listening to air traffic frequencies, and the controllers didn't have any data that they were giving out. They just held takeoffs and diverted landing planes for a while.

    They're building a crew vehicle. They have a USD$75 Million Space Act contract to build the launch escape system, which is integral to the vehicle (not a tower like Apollo) and would also be usable for precision soft landing on ground rather than water. They are contracted to finish in May, at which time it is very likely they would get a larger contract for manned development.

    Give us a good heavy launch capability, and it will be man-qualified. The money for that hasn't dried up, or we wouldn't see all of the most credible companies other than Orbital Sciences with signed contracts in that market or attempting to get them.

    That's funny! :) I work there and was on the roof, but I saw that there were people next to the SSL Annex. Would I have known that I could meet the inventor of open source, I would have gone down to the patio :D

    I am always happy to give a brown-bag talk, etc., on campus or at LBL. I only live a mile away.

    Yes. I think the truly important part is still rather far away, though. Probably beyond my lifetime. And that is a self-sustaining colony, where children are born who need not return to Earth.

    I'm not sure that's a good analogy. Rocket launches are several orders of magnitude riskier than commercial aviation, and while we can expect modest improvements, I don't see the trend changing much. Launching rockets is hard.

    In 10 years, more than 500 commercial fishermen (3% were actually women) died on the job in the United States alone. An employee who works 10 years has over a 1% chance of dying on the job.

    Yet, liability doesn't kill the industry.

    NASA would have given it to Texas, which had a runway near the museum and would not have had to chop anything. LA was only going to get the shuttle if they didn't abuse it further than NASA already has in making it "museum ready".

    Street trees last about 50 years and then are in general too sick to remain. Some of these went sooner than that, but the museum is replacing 1000 trees that will live 50 years now.

    Why should you [expect the electroate and their representatives to do what's important for the species]?

    Because that is the only cause that justifies their existence. Societies exist to facilitate the survival and growth of their population. Populations don't survive and can't grow for all that long in one place or doing one thing. Endangered species are endangered because they can't move and they can't change fast enough.

  11. Re:"The future of the species" on Space Shuttle Endeavor Lands In Los Angeles After Final Flight · · Score: 1

    Even if the only way we could survive would be through an exodus to other worlds, how does that solve the problems that would lead us to such an exodus? Until we become more enlightened here on Earth and make some progress in the nature of the human heart, we will only bring those problems with us.

    This is like saying that nobody should have children until we discover a way to keep them from getting cancer.

    The urge to propagate to other places (islands, continents, and now farther) is just a larger form of the urge to have children. They will live their lives, fight, have wars, die, or do other things that we can not conceive of. Only by planting the seed of humanity, warts and all, do we give them the chance to evolve past us.

    If [aliens have] managed to solve the problem of interstellar travel, they're probably praying that we'll become more civilized before we escape the bounds of our planet.

    I don't think you are putting your own birth in context. You are the cumulative result of millions of generations of fights to the death. The beings who lived passed their genes on to you, the ones who were out-competed did not. That means that you are extremely highly optimized to be the nastiest SOB out there, the one who lives and competes successfully for the resources necessary to reproduce (including a gender-opposite partner) while others lose. Only recently, in evolutionary terms, has your species developed society as a means of collectively optimizing the survival of their DNA. You are only evolved to be nice to the extent that it promotes the survival of related DNA.

    You are theorizing other species whose evolution doesn't follow the same rules. Fine, they're called Aliens because they're Alien. You should not automatically assume that your idea of altruism would apply to them at all.

    The Russians are commercial spaceflight right now. But we don't see them doing it with new engineering, so in general they are not looked upon as a future path.

    You are expressing a whole lot of confidence that the Chinese will not have a revolution or economic failure, and will succeed in bootstrapping a program that hardly exists today.

    The minute private interests lose people on their own ventures you'll see how interested they remain in pursuing it.

    If this were the case, we wouldn't be riding jet planes everywhere.

    The only time something is shut down in connection with an air crash, it's something that was already on the edge of economic failure. Like the Concorde and Pan Am.

    The Russians have the same capability that we would have today if we kept building and launching Apollo command and service modules on Saturn 1. If you want to see how bad things are there, look at what happened to the one remaining Buran.

    Commercial spaceflight is really the only hope. And so far we have one company that appears to be capable of doing it, and a very large number of failed efforts, which I guess is what is to be expected. We're really lucky to have that one company.

    Don't be so sure. Our democracy is heavily manipulated by wealth, and not all votes have the same weight due to an antequated thing called the "Electoral College". Essentially, my vote in California will not be as important as a vote in a "swing state" such as Ohio.

    I think we mostly have a plutocracy, like most places.

    I went on the back patio of the Space Sciences lab at Berkeley, up the hill from the Lawrence Hall of Science (the "Command Center" building in the movie "Colossus: The Forbin Project").

    Nice low-level flight right over Berkeley.

    My kid was in class, heard the sound of the low-level flight, and they all saw it right out of the classroom window.

    Gee, the end of an era. We could have had so much more. It's good that we have SpaceX doing something sensible about space flight, and NASA funding enough of that, but I think we learned one sad lesson from the Space Program: You can't trust the American electorate and their political representatives to do what's important for the future of the species.

    The main reason that CyanogenMod can work on Android is that the kernel is under GPL and so is the Android platform (though of course not most of the applications). So, the developers get to start with a working system despite what the manufacturers want. This is not the case with a Windows platform.

    Hi William,

    You might be correct that the overhead of instruction decode is not so significant. I think, however, that emulating all of the architecture goes far beyond just instruction decode. The Medfield reference benchmarks we see, it's about 1/2 the normalized battery performance of iPhone 4S.
