This machine delivers tons of materials (which nanotechnology isn't going to do anytime soon; even a nano-technology-based machine to deliver tons of material is going to be macroscopic if it's going to work in a day or less!), nano-machines come in later to maintain and repair the wall as it cracks.

    (Someday, w/ super-hyper-ultra nanotechnology, the entire wall may be made of self-repairing nanomachines, but we may not get that far. The previous paragraph is well within sight, even if it is not currently feasible, without Drexlerian nanotech levels.)

    No matter what resolution you rise to, you will always be short of analog.

    You seem to be laboring under the misimpression that analog has "infinite" resolution, and/or that it is always better then digital.

    That is false. Analog has a resolution, it just tends to be fuzzier, rather then in rigid squares. With the right system we could also display digital signals "fuzzily", nobody cares enough to do it.

    DVDs (digital) beat VCRs, hands down, in the resolution department. You may notice the artefacts more, but you'll still be getting much more detail then the VCR gives you, and like I said, if we wanted to fuzz the artefacts out we could.

    It is still stupid that marketers use "digital" synonmously with "quality", but the opposite is not true either. "Analog" just has a different characteristic failure mode, one that happens to look better to us, but is still failure.

    (Note that if analog did have infinite resolution, then the old joke about using a copying machine to look at a benzene atom by successively enlarging the image wouldn't be a joke.)

  7. Re:Timeshifting on EFF Suing The FCC Over Broadcast Flag · · Score: 4, Informative

    "Fair use" is a technical term, and "timeshifting" is not now and never has been "fair use".

    The courts did rule in Sony v. Universal City Studios (1984) that use of VCRs is primarily for time-shifting, and that such use does not harm the value of the work to the copyright holder, thus the courts refused to ban VCRs. However, there has never been any ruling, implied or otherwise, that copyright holders are obligated to assist us in our fair use, or prohibited from engaging in other technological measures to prevent us from engaging in activities that might be defended as "fair use".

    Slashdot in general has a very, very, very unbelievably wrong idea of what "fair use" is, to the point that it has virtually no connection with what the legal concept actually is. Fair use is a very narrow allowance to use small portions of copyright works subject to severe limitations, no more. There is no such thing as a "fair use" right in law. (Which isn't to say there shouldn't be one; I do in fact argue that something like it should be protected. But that doesn't make it magically appear in the real law we have now.) As a result, the flag can not infringe on our non-existant "fair use right".

    The reason why I continue to post this point, despite continued evidence that Slashdot as a whole refuses to understand this, is that the misunderstanding is dangerous. Thinking you are protected legally means you won't do anything to protect a "right" you think is safe. It's not. Fair use doesn't do shit for you unless you fit into the narrow provisions as described in the link above, and Slashdot as a whole needs to stop thinking otherwise or we will continue to have our "fair use rights" "stripped" from us, with no coherent protest.

    I can think of many interesting legal/ethical conundrums regarding the right to kill though:

    This type of ethical conundrum is typically a waste of time because no real-world situation can be cleaned up to a one-sentence question, and most of them are so unlikely to happen as to not be worth basing a philosophy on. For instance,

    Imagine if there are 100 people about to be killed and the only way to save the other 99 is to shoot one of the 100.

    In the entire history of humanity, has there ever been an instance where this actually happened and the choices were that clear cut, shoot or don't shoot? (Even if there have been one or two, that's still nothing.)

    In this case, the reason the "answers" are hard is that the questions are unreasonably hard. In real life, the question of defending one's home with lethal force is not an easy one, but it is at least constrained by the realities of the situation. Nobody is going to break into your home and threaten to kill ten strangers unless you allow them to kill your spouse. And even if they did, the odds of them being truthful aren't worth worrying about anyhow.

    But no real "fossil" could be obliterated by rolling over in, in Martian gravity no less. The same thing promoting righteous outrage proves that it wasn't a rock in the first place. Even if it "broke up", you'd still see pieces.

    Mars isn't the moon, it has an atmosphere; if it broke completely into dust when subjected to such a small force, it would have long since weathered to nothing. A fossil would have to be a rock that has survived millions or billions of years already; rolling over it isn't going to do any more then the wind that would have 'exposed' it, as it would have blown right away with the surrounding dirt.

    Well, in my case I'd call it empirically true. The only ugly thing was my teeth, but they were pretty bad. Nearly the only time I ever swung a softball bat, I took my thumbnail off with a hit from the ball. (Literally, though it took about a week. Had to grow a new one. Didn't even know that was possible. Scored a few "gross-out" points for pulling my thumbnail off in the middle of class; no one was more surprised then me. ;-) ) I could play T-Ball but only because the ball wasn't moving.

    Once I got glasses in high school, it all changed. I could hit baseballs. I could sink baskets. (I consider myself lucky I was close enough to normal vision to develop depth perception at all; some people don't. I must have had normal vision when I was young.) So I can state with confidence the fact that I was unusually bad at sports. (Last one chosen for anything, even basketball, even as the tallest kid in class.)

    As for your introversion, I recommend taking the full Myers Briggs to find out your personality type (you may be an extrovert after all).

Myers Briggs can only measure what you are now.

There I committed three sins: I was ugly (a tooth issue not diagnosed correctly until later), uncoordinated and couldn't play sports well (just nearsighted enough to ruin my depth perception, also undiagnosed for many years), and I knew stuff (could already read and do simple arithmetic in kindergarten). Hattrick.

    I'm sure I wasn't a social wonder in kindergarten, but who is? My point is, I never had a chance. Now I'm introverted. What choice did I have?

    Mind you, I'm happy enough with the outcome; you can't hear my tone so this might sound bitter. It's not; to me this is just how I am, I figured this out years later.

    "But what about his hair?" Well, social skills form via feedback, which must be both positive and negative. If a kid is simply ejected from society at a young age, then he's never had an opportunity to learn about hair styling; he literally doesn't know about it. I recall not caring, either. So even to the extent that you may have a kid clueless, it may even be a result, not a cause.

    Can society take the whole blame? Beats the tar out of me, but I doubt it. Maybe he's got a light case of Asperger's syndrome... I'm pretty sure I don't, though. But you can't write the effect of his society off, either. I recall trying to reconnect and being firmly ejected over and over.

    How does this help? I don't know. Let me know if you find out. Seems people don't get mature enough to allow kids to re-enter society until somewhere around high-school. Getting out of his age group might help.

    (Stuff like this makes me strongly sympathetic to the homeschooling system, which often involves significant out-of-age interaction, short-circuiting the need for every kindergarten class to reconstruct society from scratch; is it any surprise they get it so wrong? What do you expect from five-year-olds?)

There are quite a few other criminal cultures too.

    They meet every criteria for a looser definition of "culture", such as one might describe a hacker "culture" or a sports fan "culture". Of course, they aren't a seperate culture like "US culture" or "French culture", but from context, most people won't mistake the two.

    You seem to be seeing an implicit claim that "all cultures are equally valuable", which is a post-modern conception. While there are some academics who would take it down to the finer-grained culture definition (e.g., "hacker" and "ecstasy"), most people apply that only to the coarser-grained one ("French", "Chinese", etc.). Most people would agree that there definately are some cases where one [fine-grained] culture is clearly inferior to another, so by calling the script kiddies a "culture" doesn't logically imply that there is a claim that their actions are OK because all cultures are equal. (There are even some atavists like myself who reject post-modernism entirely; makes it easier to ID implicit post-modernism it when I see it then those who are steeped in it.) Given a choice between a person joining script kiddie culture or joining a sports culture, I know which is more likely to turn out well for both the person and culture at large.

Similarly for "free speech activists"... other then similar beliefs on free speech issues, that doesn't otherwise imply an outlook, a unique jargon, dress patterns, frequent organized or semi-organized social encounters, etc. that one would normally associate with a "culture".
