    If you could find a way to design a self replicating spaceship, you could send them off programmed to replicate and occasionally fly through a black hole that was likely traversable. If they survived, they'd work out what the rules for traversal, and then fly off to find the right kind of blackholes to make their way back to the spacetime coordinates they started from. Essentially, they'd solve the problem of flying in a closed timelike curve back to their point of origin via lots of wormholes by a sort of evolutionary brute force - lots would fail, but that doesn't matter since the only ones you care about are the survivors.

    If it all worked, you'd send one ship off, and then lots of it's distant descendants would come back, with the data you need to travel in space and time using blackholes.

    Then you could do all sorts of cool stuff. E.g. ship that travels somewhere millions of light years away at 0.9999c but make a detour via a wormhole. Sure decades or centuries of ship time would pass for the crew members, but you could probably put them in suspended animation. But the big problem of millions of years of time passing from the POV of an observer at rest could be fixed if you could make a wormhole journey that takes the ship millions of years back in time somewhere along the way.

    So from the POV of a crew member, they get in the ship, get frozen or whatver and wake up millions of light years away.

    From the POV of someone on Earth the ship arrives at it's destination quickly maybe even instantaneously, and it could come back quickly too, since unlike a normal relativistic rocket it doesn't arrive millions of years in future from a rest observer's POV.

    From the POV of the ship itself, millions of years pass each journey, but that's no big problem.

    In fact, theorists say one variety of wormhole wraps back onto itself, so that it leads not to another universe, but back to its own entrance.

    I think they should call these "Scenic Tours"

    "Greetings Crew. Our esteemed leader, Star Captain 91805, will explain the reason for this meeting, and then the view screen and instruments panel will be unveiled."

    "Esteemed crew members. I checked the calendar this morning and it is Earth Day 2,345,621,341 of our voyage. We have been in the wormhole for 6,426,359 Earth Years. After many generations of no readings in the void between the universes our instruments have recently picked up energy signatures of a star system. Curvature readings indicate we are approaching the mouth of the wormhole. Many generations ago, our distant ancestors set forth on this great journey, and they predicted this day, Emergence Day, even though they thought the journey would only take 867 days, or just under two and a half Earth Years. Luckily, we have a food generator, and our medical bay was able to clone members of our all male crew when they became too old to work or were executed. The first captain's clone became the new captain when he died of old age, and that pattern has been repeated 91805 times for all crew members. We have, I think you all agree, made sacrifices to complete this journey. I found that before the voyage, the food generator could make any known food. Unfortunately, Science Officer 23 accidentally erased most of the its memory crystals whilst attempting an experiment to turn the ship around, and we have since all lived on a rather limited diet of "condensed milk", "dog biscuits" and "toothpaste", the only meals the food generator can since produce.

    Crew morale has improved since my ancestor, the Lawgiver, Captain 25 reprogrammed the maintainance droids to keelhaul crew members for violating His Law or disrespecting His Person but we still felt that the Date of Emergence be kept secret to keep the ship functioning smoothly. But according to our instruments we will reach the wormhole throat in five minutes time. I will therefore ask Science Officer 92843 to unveil the instruments and viewscreen. For comparison, he will have a picture of the wormhole entrance displayed on another viewscreen with, in an ultra rare trinary star system, so you can see how different the two star systems are. He will also calculate the time/space coordinates of both the entry and exit, and the distance between them"

    Yeah, but look at it in software terms. You've got one piece of code which is a bit poorly understood but has been running for a long time. Or you can switch to something which seems better theoretically but hasn't been tested.

    The odds are that the next hundred years will be like the last hundred years, i.e. +0.74 (± 0.18) Degrees Celsius. Or you can try something new, to try to reduce CO2 to pre industrial levels, which is risky because no one has tried it, outside of highly questionable computer models. And it would cost a fortune. And the oceans might compensate anyway, as this dude pointed out.

    Seems like a no brainer to stick with the status quo. It's not like we have any choice really, since no one has the kind of control of humanity to influence them to all work together to change the trend, and no one really understands what the long term effects of trying to change it are anyway. If increasing CO2 causes some kind of climate flip, we'll just have to live with the new climate. My guess is that we can extrapolate the last hundred year's trend, which means that we have a few centuries before something really nasty happens. By which time, humans will hopefully have stopped burning fossil fuels and have the kind of science and technology which could actually control the climate. But it's not something you or I or even our children needed to worry too much about.

    I find this idea somewhat concerning. All too often the human race is guilty of doing things because they can, before they learn whether or not they should. I'm all for reducing carbon emissions, but in all honesty, what the hell will we break if we start trying to extract too much carbon from the atmosphere.

    I agree! The precautionary principle says that you should change with the natural world unless you know it's safe. Historically, atmospheric CO2 levels have been rising slowly for a hundred years or so. Possibly some of that is caused by humans, but it seems we should stick with the status quo until we have more evidence as to how much, and whether increased CO2 is a good thing, a bad thing or doesn't matter at all.

    It's possible that lowering CO2 suddenly might cause the climate to flip into a new stable state, like a new Ice Age. Since the costs of this would be vast, it's very important not to take any measures which could allow it to happen. If irresponsible Europeans persist in sequestering carbon, the US should increase it's carbon emissions to compensate to ensure that the current trends continue.

  13. Re:Marketting hype? on Next-Gen Processor Unveiled · · Score: 1

    The most important difference is in the ISA, which allows the compiler to express dataflow graphs to directly to the hardware, which will work best (compared to convention) in ultra-small technologies where the wires are quite slow. To get a similar dependence graph in a RISC or CISC ISA, a superscalar processor must reconstruct it on the fly, instruction by instruction, using register renaming and issue window tag broadcasting. Thanks for reading.

    That reminds me of EPIC aka Itanium.

    It seems like the original RISC idea was to design the ISA so it was easy to build a scalar, pipelined processor. But in a modern superscalar chip, scheduling lots of instructions requires huge amounts of hardware, and that tends to limit clock speed. x86 chips have figured out how to break x86 instructions into something which can be executed efficiently, but both x86 and Risc chips are held back by scheduling instructions.

    So EPIC tried to move the scheduling logic back to compile time. Which all sounded like a good idea in theory, but in practice EPIC seemed to be a massive disappointment. I remember reading that mid range x86 outperformed them in SpecInt when both were running native code for example, despite the fact that mid range x86 chips were much cheaper to buy, and presumably to manufacture. Even Risc back in it's prime (e.g. Alpha) had a performance advantage in this sort of test, though nowhere near enough to take over.

    So where do you think EPIC went wrong? What does your architecture get right that Intel/HP didn't?

    As far as democracy is concerned, you don't live in a democracy (assuming you live in the U.S. or Europe). The U.S. is a constitutional republic, and the important aspect of such a government is the constitutional limits, not the elections.

    Actually the UK is closer to a democracy than a constitutional republic. Just the ask those Islamist dudes interned in Belmarsh now, or the IRA guys in the 1970's, or blackshirts in WWII.

    The EU Human Rights Act the press and judiciary dilute this admittedly, but historically in the UK Prime Ministers can use all the powers a medieval king had to lock up people they don't like. The government still needs to win a vote of confidence for really unpopular things, and an election every few years. But they can call the election when they are at the height of their popularity cycle, so you need to be be pretty ghastly before they'll use them against you.

    I think in scheduler terms this means that processes which are taking an unfair amount of CPU time should have their priority lowered.

    Insane is not really the right way too look at it. A better question is how much they understand the outside world.

It seemed to be for two reaons, Saddam thought war was inevitable, since the US wanted it. Secondly, no one dared question him. The thing is, if he'd announced a pullout before the UN forces attacked, the coalition would have split despite the US's best efforts. As Kanan Makiya put it, Saddam had a very good understanding of Iraqi politics, but a very poor understanding of international politics.

    I can see with Iran the same sort of misunderstanding of their opponents' bottom line could well doom them to a war with Israel for example, since inside Iran Israel is so demonised that it's hard for anyone there to make any attempt to understand what makes them tick.
