  1. Re:Back to the future 2!! on 'Flying Saucers' to Go On Sale Soon · · Score: 1

    Hey, if you assume "Mr. Fusion" power supplies, flying cars are easy, even without the anti-grav technology implied in the movie.

    It's all a question of power/weight ratios, which is why nobody had any success with ordinary heavier than air flight until the internal combustion engine came along; steam engines just won't cut it. Hook up a Mr. Fusion to some high power electric motors (it's the battery weight that kills you for electric powered flight) and away you go.

    Noisy, though. (Without antigrav or wings, the only way to lift a flying car is by moving large volumes of air. If you restrict the cross sectional area of that column of air (ie, no helicopter-like large rotor blades), the air has to be moving fast. Fast moving air == noise.)

    That wasn't true even in 1991, except maybe for Intel processors which are notoriously wasteful of clock cycles (which is why they have always advertised clock speed rather than instructions per second). A 1 MHz MOS 6502 was just as fast as a 4.7 MHz Intel 8080 (and needed fewer support chips).

    If you throw more transistors at the problem, and/or different architectures, you can complete instructions in a single cycle. (Especially e.g. register-to-register instructions where the answer comes out of the inputs at the speed of propagation delay through the gates.) If you do it right, you can even design clockless CPUs where the completion of the previous instruction triggers the start of the next one without waiting on an external clock.

    This assumes your CPU is not microprogrammed; the instruction words contain the relevant bitmasks for source and destination registers as well as the control code for the ALU. See for example the PDP-11 instruction set (IIRC).

    Of course as others have pointed out, modern processors pipeline multiple instructions at different stages of execution at the same time, for a net throughput of multiple instructions per cycle.

    I don't know about "Heroes", but some cable-channel stuff just isn't available over the air, or at least not until years later when it goes into syndication (eg Stargate).

    In which case the alternative is to buy the end of season DVD set, which is what I do. (Gave up on cable and satellite years ago, and have little patience for OTA programming with its ads and watermarks.)

    For that matter my local library has the sets for some of the shows, which is great for getting a taste for them to see if they're worth buying. I think I'm at about #18 on the hold list for "Eureka" right now.

    Depends. What's the risk factor involved? And how's your cashflow? Can you afford to pay your attorneys plus legal fees for the year or more that the lawsuit drags out? What if the troll gets an injunction against you selling your product that they say violates their patent? How are you going to pay the bills then?

    Going to trial is always a crapshoot even if you're 100% sure that you have a solid case. Nasty surprises happen (jury goofs up, judge makes a bad decision -- can your cashflow survive the appeal process? -- etc).

    Not that fighting patent trolls isn't a noble cause; I wish more people would do it. But plenty of people see discretion as the better part of valor. (As witness the amount of crap people submit to before boarding a plane these days.)

    Probably. But if you're a (smallish) business owner, do you want to go that route and spend time and money tied up in court proceedings or just pay the man a few bucks to go bother somebody else?

    And in response to another poster, than only marks you as an easy touch if the details get out. The patent troll sure isn't motivated to let others know what you settled for, and both of you would have an interest in plastering the settlement with NDAs.

    Its one reason that patent (etc) trolls usually go after smaller businesses first. That was one of the odd things about the Caldera-SCO case: they went after IBM first, undoubtedly expecting to just be bought out altogether rather than actually have to through with it.

    I don't think that's true for most of them any more than you do (unless you're stupider than you look).

    I doubt most ODF "advocates" would have any problem with another ISO open document format standard that made technical sense. MSOXML of course doesn't make technical sense: it is self contradictory, contradicts a number of pre-existing ISO standards (1900 as a leap year, anyone?), and is insufficiently specified to implement properly ( SpaceLikeWord95 tags?).

    It's like complaining about a dog turd on the sidewalk and being accused of not liking dogs. No. Like "OO"XML, the complaint is because it's shit, not because of where it came from. (Except perhaps for a few folks.)

    It also drops it if you try to PPTP tunnel through it. (Heck, sometimes it annoyingly drops for no particular reason at all, especially if I'm doing wireless with a less than 100% signal).

    To get to the VLAN which lets me connect to the RILOs (through which I can remotely power off servers, among other things), I VPN to the corporate network, ssh to a dedicated security server, ssh from there to another server which guards the subnets for the servers I manage (on private IPs), and from there to one of the servers in that subnet which can actually talk to the VLAN the RILOs are connected to.

    I think the "new discovery" part is the "without supernova remnant". Aren't most pulsars embedded in their supernova remnants?

    May be an age thing. If the object is young enough that the remnant is still nearby and visible, it's young enough that it hasn't yet shed a lot of energy through its pulsar (etc) emissions, and vice versa. An old neutron star whose remnant nebula is long gone is likely to be a slow, feeble pulsar at best.

    The scene in "2001" was adapted from an earlier Arthur C. Clarke short story, "Take A Deep Breath".

    By the time of the movie, Clarke was aware of Air Force research in high altitude chambers that people could indeed survive brief periods of vacuum exposure (although unconciousness results after 15-30 seconds from oxygen starvation, so you'd better have help or get pressurization underway by that time). However, as a SCUBA diver, Clarke would also have known that holding your breath during a sudden decompression (as Dave did in the movie) is a virtual guarantee to get a lung embolism or worse. Dave should have been exhaling when he blew the hatch, it's not like you can hold your breath against a pressure differential of even 3 PSI (if the pod was pressurized with pure O2) let alone 14.7 psi (air).

    You forgot to mention Christopher Columbus's theory that the earth is round... [...]when the rest of the so called "Intelligent" people of the world said it was flat.

    LOL! You still believe that nursery school myth?

    NO intelligent person in Columbus's time thought the world was flat -- as it clearly is not to anyone sufficiently observant. Columbus's problem is that he wanted to go to Asia via a western route, and everyone intelligent knew that with a circumference of about 25,000 miles, Eratosthenes having calculated it about 240 BC (as others had since). Hence they "knew" that with the sailing technology of the day, there was no way Columbus could make the voyage.

    They were right, too. Had the Americas not been in his way, his expedition would have perished before he got as far as the longitude of Hawaii.

    There is some evidence that Columbus may in fact have known that there was some land mass to the west considerably before Asia (the Vikings certainly did, and it is quite possible that fishermen who went as far as the Grand Banks were also aware). Whether from that he decided that Eratosthenes was wrong and the circumference was smaller (possibly influenced by Ptolemy's maps (from Geographica) which underestimated the circumference at about 18,000 miles), or whether he was just arguing that way to get backing for an expedition (with the secret purpose of discovering and exploiting just whatever land mass was there), we have no way of knowing.

    That mistake alone discredits the rest of your post as to make it not even worth reading.
