  1. Just an educated guess... on Longhorn: Fewer BSODs, More RSODs · · Score: 4, Interesting
    Triggering a BSOD from kernel mode is quite easy actually. The most common BSOD I personally have seen is the IRQL_NOT_LESS_OR_EQUAL one. This is actually akin to an assertion failure, because if you call a function which requires IRQL_PASSIVE at anything but the passive level IRQ level, you will get a BSOD, even if the call would not have resulted in a page fault or anything.

    So there's actually a lot of BSODs that are 'preventative' in nature. That is, the kernel says "uh oh, that call should never have been made, the system *might* become unstable, shut it *all* down before any real damage is done".

    Then there's "Boot disk not found", or "Boot disk failure", which are in fact real serious, because it's the end of the line for the machine.

    Maybe they've broken down errors that are likely Kernel driver programming mistakes, and errors that indicate the system is severely damaged.

    Aircraft carriers and warships can go at 15 knots speed at least. (Just making up that number, but it is at least that amount).

    A 13" paper plane will have no chance of returning alive if it isn't taking off from a stationary carrier in calm see and no wind. It will have a very short range and speed. Bottom line: will it ever be able to see what a powerful set of binoculars wouldn't be able to see from the carrier anyways? And also, what't the point of having the stealth of a 13" paper plane, when just a few kilometers away is a ginormous aircraft carrier?

    Just questions...

    Yeah, I fully empathize.

    Thing is though, that engineering beauty and mathematical beauty are different things. You have to understand that the problem you were solving here was the equivalent of your learning how to integrate in math. (Integrate all known forms of equations). The beauty isn't in that excercise, the beauty is in what it produces.

    To make it much more evident, when people talk about "Engineering works of art", they aren't refering one least bit to how the equations were solved. They're much more often refering to the elegance of the final product and that elegance is very often linked to the product's utilitarian nature. For example, that an F15 fighter jet can actually deliver twice its weight in thrust. When you think about it, that's quite elegant: it's a plane that's made so light and durable and so powerful at the same time, it could lift off like a rocket. It's probably the equivalent of trying to put an SUV engine onto a trycicle and actually making it work.

    Whether the engineers used analytical equations to solve it, or plugged into a TK-solver is quite irrelevant. In fact, given the nature of those jets, they probably actually just needed an order of magnitude rather than a super precise value of the forces to be applied (generally, in engineering, when they say it is designed for 5000 lbs, they actually make sure it actually holds 10000 lbs or more).

    In the end, it comes down to Descarte versus Hume. In the empricial world, it is preposterous to say this rope will snap at exactly 112.58 Newtons. Because it might just not... it's much more sensible to say, 110 Newtons is around the threshold. If I were betting my life on it, I'd put no more than 60 Newtons.

    It's all about your perspective on life:

    All three answers are actually correct, in that they're accurate, however differently precise descriptions of Pi.

    This reminds me of my earlier years in high school when my physics teacher would get really annoyed at the students who would put in answers like "3.52302881055" when clearly, the margin of error was at the first decimal.

    My point: when we were kids, there was a stigma associated with the number of digits after the decimal you could get out of your pocket calculator. A sort of "More is better" mentality.

    Without digressing, my point is that the engineer needs no more than 3. Knowing more, or wanting to cram more would be like driving an SUV inner city... it would be overkill.

    Aside from the elitism of how precise our representations of numbers are, I think the real debate comes as to how much creativity is involved in the three disciplines. I personally believe that all three have the potential to be extremely boring and also extremely creative disciplines.

    Fyi. I grew up in pure physics, switched to pure math, and eventually ended up being a software 'engineer'.

    That makes no sense. It's the same issue as digital signatures... or any ID theft issue. Take this scenario:

    You rent a car, go in a drug store, come out to find the car's been jacked. You see the said car careening down the street and eventually mowing down 8 pedestrians including one pregrnant woman and two children.

    What good is it that your driver's license was on file?

    Even better:

    You buy a gun. Use it over and over at the shooting range. Someone takes it, kills an officier. Your prints are on the gun. What does it prove? Absolutely fucking nothing.

    So your driver's license being in a DB has absolutely no legal value. The *only* value it might have is for the insurance company. But then again: if you are in an accident, you *have* to show your driver's license at which point, it can easily be determined if it's valid or not (by the insurance company via the cops). The rental company would, for its own benefit make sure the license is valid, because should the car crash, and the license be found invalid, the insurance company would refuse to pay. But it wouldn't need to store this data at all since in the case it will be necessary, the data will be looked up anyways.

    I see no scenario where you need your identity logged...

    I don't know if you are being a troll or not but I can answer you:

    I firmly believe that my mind is in control of me. But that doesn't mean I'm just deterministic behaviour. It's the exact same scenario as software on hardware. If a CPU is broken in a special enough way, there is no way for software to be able to detect whether it's on a healthy system.

    Saying that however, doesn't mean software *is* hardware.

    Or, to bring the analogy back over to our side: saying that our mind and body is completely in control of our soul isn't the same as saying our sould *is* our mind and body.

  17. Re:I agree - I've experienced this personally on Study Points to Sixth Sense in Humans · · Score: 1
    I have a similar one too:

    I ride my bicycle inner city a lot. And I've been doing that since I've been 13 or so (when I used to live in Istanbul, Turkey). I'm extremely comfortable riding in high traffic situations. But here's the thing that amazes me the most, when I'm at an intersection waiting for a red light, no matter what I'm doing (and I rarely ever stare at the red light, or in fact in the direction of the light), something goes off in my mind and my foot will automatically get off the ground and clip in just about 3 seconds before the light turns green. This is almost always without fail.

    The other thing is that I can sense when I light is about to turn when I'm arriving towards the intersection.

    I firmly believe that my brain has a pattern recognition system for the amount of traffic at the intersection. For example: the longer the car pileup at a red light, the longer it has been red, and the lesser the traffic on the green side, the more likely it is to change red (since the congestion has been cleared by then).

    Thing is, I noticed this and started thinking about it one day when I was completely absorbed in some thought, and watching something on the pavement, completely unaware of the world, when I just clipped in and started pedaling... And the light turned green right then. Then I started paying attention to this behaviour, and sure enough, it's pretty consistent.

    I also think that you can 'teach' your pattern matching system by reinforcing with a "good" or "bad" feeling. For example, when I did that pedaling trick that day, I realized that sometimes there is a priority left turn for incomming traffic... and the thought kind of made me feel this "panic" inside. Sure enough, since then, the way I perceive those has changed too...

    Overall, I think it's our greatest strength. It's 'mu-shin' as the japanese say it: "no mind".

    I agree with you but there is some merit in this. Not enough to make a story called "the sixth sense" though.

    All IMHO, the brain is a humongous pattern matching system. It learns by ways of emotional or genetic reinforcment. It might very well be that in fact seeing animals flee, even if they're just walking uphill might trigger a dormant pattern and pop up a completely irrational thought that maybe it's time to go up too.

    But this is the equivalent of software. Not an additional hardware function that perceives stuff (the sixth sense). That would be like calling intelligence your 7th sense.
