  1. Terraforming? on Firefly Premieres Tonight · · Score: 2
    No, the writers couldn't be bothered to really think through the implications of the future they were trying to create.

    How about the terraforming aspect? If I heard the narration properly, Earth has been abandoned, or reasonable equivalent. All of this action is supposed to have taken place in another stellar system, where early settlers terraformed a large number of worlds.

    How long would terraforming a world take? What would a candidate for terraforming look like?

    SETI Astronomers posit a zone where a planet would have to be to have possibility of liquid water. It is narrow. Two planets in this zone is probably the limit, not the multitude that the shows creators have.

    Could those settlers have moved Titan sized bodies to the habitable zone, for terraforming? That would take a lot longer than a few hundred years. Terraforming, even with nanomachines, and perfectly genetically engineered bugs, would take a lot longer than a few hundred years.

    One thing I feel sure of, no culture that had the tools for terraforming at its command would still employ labour intensive hard rock miners.

    ...Try this: Hold a pencil about a foot off the ground on a sunny day and you'll see a shadow. Raise that pencil to an altitude of, say, 1000 feet and you won't see any shadow at all.

    Okay, now try this thought experiment. Hold a length of window screen an inch off the ground. If it is close enough to the ground you will see the individual wires. Now raise that screen up a yard or two. The shadows of the individual wires will fade away. But you will still have a shadow the shape of the screen. Raise that window screen the 1000 feet you mention, you won't be able to detect the drop in insolation it causes. But tell me, if the window screen was a couple of square miles in area, do you think the drop in insolation would still be undetectable?

    It seems to me the smaller the particle size the greater its ability to block or reflect light. Wouldn't you agree?

    Likewise, if you have a non-solid ring of small debris circling the earth at, say, 1000-24,000 miles there will be no effect. Certainly nothing that could effect the climate.

    What?

    Do you believe in free speech? Do you believe the way to counter a view you don't agree with is to suppress it? Do you believe the way to counter a view you don't agree with is to swear, and call the other person names?

    Did you know there is another approach? You could try to explain what you disagreed with.

    Read what the guy said. He said the USA was justified to issue wiretaps to suppress violence. He said that the USA needed more wiretaps because it had an ethnically diverse population.

    What about due process? Should tools like wiretaps be used for suppression, or should the authorities wait until they can document good reasons for their use?

    My reading of El Camino SS's contribution was that he was prepared to see wiretaps used for suppression, without any of this time-consuming respect for civil rights. That is my honest interpretation -- not a troll.

    we would end up enslaving them, but we would have to wait billions of years for life to develop. Either that or we could bio-engineer our own race of slave labor and RULE the universe. Reminds me....God I love being American, I can be such an asshole.

    Yes Americans can afford to be assholes, without consequences. Oops I forgot about two big towers that aren't around anymore. I guess there are consequences to being assholes to others.

    Dresden and Hiroshima being two more consequences to being an asshole...

    For the record, the bombing of Dresden was an experiment. Dresden had escaped being bombed up until a few months before Germany's defeat. It didn't have any military targets. It hadn't been considered a military threat. Bombing it didn't have enough military value.

    Bombing military bases is considered "counterforce", because the base has weapons that can be used against you. Bombing military barracks is considered "counterforce", because it houses soldiers who could fight against your soldiers. Bombing factories that produced strategically important supplies is similarly "counterforce". Allied strategic bombing during World War II wasn't very accurate. Jacob Bronowski, whose war work was to analyze how successful strategic bombing was, said the average ww2 bomb had a 50% chance of landing within five miles of its target.

    So, is bombing the apartment buildings around a strategically important factory "counterforce" or "countervalue"?

    Whatever. Dresden didn't qualify. IMO Dresden was terrorism writ large. IMO Dresden was a war crime.

    So Dresden provided a perfect experimental subject to answer the question "what happens when you dump enough incendiary bombs to generate a firestorm in a intact city?"

    If a fire is large enough, and hot enough, the updraft it generates can be so strong that it causes hurricane force winds to rush towards it, from all directions. Even people in deep bomb shelters in Dresden died. The firestorm consumed all the oxygen, and they suffocated.

    The allies had already firestormed Hamburg. But Hamburg had already been bombed up during more conventional attacks. Its streets had been torn up. Fire mains probably required repair. Fire engines and fire stations were damaged or destroyed. So it wasn't a sufficient test of how a city with an intact fire-fighting infrastructure would survive a firestorm.

    Because Dresden hadn't been bombed it was more like a peacetime city. Because Dresden hadn't been bombed, bombing it could provide strategic planners with clues as to how to fight world war three. It could provide strategic planners with clues as to how damaging a sneak attack with atomic weapons could prove, after the war was over.

    Tokyo too was firestormed.

    I believe that Hiroshima and Nagasaki had escaped attack up until the atomic bombs were dropped on them.

    So, remind me, who were the assholes in these cases again?

  6. Re:2nd world has high-end labor on Low-Budget Indian Satellite Launch · · Score: 2
    This is the 2nd time this month where a slashdotter has incorrectly assumed they knew what the 2nd world or 4th world is... presumably because they misunderstood the term "3rd world".

    Third world is a term from early in the Cold War. Those who coined the term saw all developed Western nations lined up against a monolithic communist bloc. In those days there was hardly any trade between Capitalist countries and Communist countries. It was like they were on two separate planets. The third world referred to technologically underdeveloped, non-aligned nations.

    Nowadays third world may have lost its idealogical roots. But it still bugs me when people invent their own meanings for 2nd world, 4th world, etc.

    The 2nd world would be former communist bloc nations. Don't use it for other meanings, OK?

    I like MickLinux's characterization of IMF loan repayments as "tribute". In the most (formerly?) corrupt nations the west made huge loans to these countries. On paper the loans were made to aid development, but corrupt cronies the west installed, like Mobuto Sese Seko of Zaire, diverted those funds offshore to their Swiss bank accounts.

    Yes, the "middle east" was more advanced than Europe for a long time. I am not sure that corruption is the explanation of Europe's rise over the "middle east". By today's standard things were pretty corrupt in Britain even 200 hundred years ago. Somewhere I have a copy of Marvin Kitman's very funny "The making of the President, 1789" and "George Washington's expense account". By today's standards Washington's corruption make the Gates, Ballmer, and the CEOs of worldcom, ENRON etc look like choir-boys.

    We may think of India as a very poor country. But I had an Indian buddy, 20 years ago in University, who used to remind me that India was the 10th most industrialized nation on Earth. Kind of like that saying that inside every large person there is a skinny person screaming to get out. So the billion or so people in India includes more college grads than many smaller nations.

    I don't know where India ranks now. But I read an editorial when the leaders of the G7 were thinking of letting Russia join them, to make the G8. The editorial writer said that the G7 would really have to be enlarged to be the G18 to include Russia if admission was based solely on GNP.

    Concerning the term "middle east" -- this is also a new term. What we now call the "middle east" used to be referred to as the "near east".

    Okay, let's play out your thought experiment.

    There are complicating factors -- like the hangers on from previous generations that are still fertile, and that with fewer carp eggs are hatched maybe more of them will survive, since they won't have as many other carp to compete with. Let's ignore those factors, and, for the sake or argument, work with thought carp that only breed once.

    Your assumptions were 250 normal females, 200 normal males, and 50 males with the daughterless gene, correct?

    Generation 1, 40% female, 40% male, 20% daughterless males

    Generation 2, 33% female, 33% male, 33% daughterless males

    Generation 3, 25% female, 25% male, 50% daughterless males

    Generation 4, 8% female, 16% male, 75% daughterless males

    Generation 5, 2% female, 4% male, 93% daughterless males

    And each generation from generation 2 on, since there are less females there are fewer eggs laid, and therefore fewer fish reaching maturity. Ignoring those factors I mentioned above generation 3 would be down a third to 333 adult fish, 81 of which would be female. Generation 4 would be 162 adult fish, with about a dozen females. Generation 5 would be about two dozen adult fish.

    Okay, they only plan to introduce males with the daughterless gene representing less than 1% of the current population, during the first year.

    I don't have the right tools to do the math for an addition of 1% per year of males with the daughterless gene. Maybe when I get home.
