  1. You were misled. on Solar Cells Crystallized Out of Molten Silicon · · Score: 4, Informative

    Someone misled you. Shot (for shotguns) is made in freefall using a tower. And it basically does work the way you're thinking: it doesn't necessarily solidify all the way, but the outside does, and that's enough for it to retain its shape when it hits the water at the bottom of the tower.

    Cannonballs were generally made out of cast iron. If you look at an authentic one that's in good shape, you can usually see the mold lines and sprue marks where it was poured. They were usually poured into sand molds that were then knocked away after they cooled.

    Some very old cannon balls (prior to the 18th century at least) were cast bronze or cut stone rather than iron, but most people switched to iron as soon as they were able to because it's a harder, cheaper material than bronze, and easier to work with and more effective than stone. (Bronze remained as a material for the cannons themselves well into the 19th century, though, since it has greater tensile strength than cast iron and is less likely to shatter.)

    Also, if you think about pouring large quantities of viscous liquid, you'd realize that "dropping" a cannonball wouldn't work; rather than forming a sphere, you'd probably form a teardrop or ellipsoidal shape* due to the air resistance. Forming spheres via freefall cooling is only practical (in normal Earth gravity) for rather small parts, where the surface area to mass ratio is low.

    * I'm told that if you look at the shot produced in a shot tower closely enough, all of it is really ellipsoidal rather than truly spherical, but it's such a small difference that it's normally ignored.

What makes you think that they actually invented anything? All I've seen is that they filed a patent, and one that quite a few people have suggested is meritless and ignores a ton of prior art.

    Filing a patent doesn't make you an inventor. It makes you a person skilled at manipulating the system for your own benefit; it doesn't say anything about actual technical prowess.
  3. Out of the frying pan... on T-Mobile Phone Unlocking Lawsuit May Proceed · · Score: 3, Interesting

    All I have to say is, if you think T-Mobile is bad, you should try dealing with Cingular/ATT.

    T-Mobile has the best unlocking policy and the best customer service of any of the U.S. cellular companies, hands down. Granted, that's kind of like talking about which slave labor camp has the best dental policy, but it's the situation we're left with due to the technological, geographic, and regulatory climate in the U.S.

    A few months ago I was trying to help out a friend who was the executor of a deceased friend's estate. The deceased guy had been with Cingular for years, and had a fully paid-off, very nice phone, which someone else in his family wanted (which strikes me as borderline creepy, but hey, nobody wants to let a good smartphone go to waste I guess). Cingular would not unlock it, period, even though the phone was paid off, the account had been closed, and the account holder was dead. (They even got faxed a copy of the death certificate and everything.) Every time somebody called, they just said 'sorry, we can't do that,' and then started in on their sales pitch to try and sign them onto a new plan. (Even when the person calling identified themselves as the executor of a dead customer's estate, which you'd think would be a signal to drop the sales crap.) Written communication went unanswered. Eventually I just helped the friend find a place locally that unlocked it for $15, because that was easier than dealing with the cellphone company's shit. But the absolute gall they displayed was disgusting.

    T-Mobile fails mostly through incompetence and ignorance, but AT&T/Cingular fail through malice. At least T-Mobile has a fairly reasonable unlocking policy (I never had any problem getting phones unlocked through them, personally, even before I was out of contract).

    And as for Verizon and the other CDMA networks, they're designed with screwing the consumer as a primary goal from the ground up.

  6. Re:Good on FCC Weighs Net Access Charge Decision · · Score: 1

    Telco and power deregulation are slightly different animals, though. Electric power in the deregulated market is treated basically as a fungible good; you buy watt-hours from one place, sell them to somebody else. It's basically a spot market. For the most part, you don't care where the 'power' that's running your lights came from (and there's really no way to tell, in any literal sense; we just play an accounting shell-game to determine who gets paid what).

    You can't really deal with packets that way. One person's packets aren't worth anything to somebody else. It's not really a buy-and-sell market.

    So we have the scheme that was developed in the 1980s and 90s for telcos. By and large, it worked really well. Long distance rates went down dramatically with deregulation, and high-speed internet was going down as well with LLU. Rather than working on a spot-market, like power, the telco regulation required the infrastructure owners (who were using the public rights-of-way) to lease circuits out, thus allowing smaller providers (e.g. Speakeasy) to compete by providing their own customer service and value-added services.

    It was a good balance between free markets and regulation. It didn't create a regulated, government-run monopoly (which is one way of dealing with natural monopoly situations; you just nationalize it and turn it into one big, Stalinist enterprise), but it provided some measure of control against the infrastructure owners simply running their fees up to whatever the market would bear. (Which is bad for the consumer -- ideally you want the cost of service to sink to the marginal cost of production / maintenance.) But for that reason, the telcos hated it.

    In eliminating the unbundling rules, I suspect that the Bush administration set telecommunications and domestic broadband access in the U.S. back five or ten years, and swindled consumers out of billions of dollars, most of which will never be used for infrastructure improvements.

    Spag's:

    Spag's was, from 1934 to 2004, a discount department store on Route 9 in Shrewsbury, Massachusetts. It was founded by Anthony Borgatti, nicknamed "Spag" (short for spaghetti, his favorite dish). Until 1996, customers had to bring their own bags, hence the slogan, "No bags at Spag's." When Spag died in 1996, his daughters took over until 2002, when they sold it to Building 19. The location became Spag's 19, and in September 2004 Building 19 owner Jerry Ellis said the store was not profitable in its current format. Spag's merchandise and operations were converted to Building 19's format. October 3, 2004 was the last day of business for Spag's. For much of its lifecycle, the roof of the main building had the name "SPAGS" written across the east roof, but this was painted over in 2005. Other businesses surrounding Spags, including The Ground Round family-style restaurant, have since closed due to lack of business. In June 2007 tentative plans were announced to close Spags 19 and demolish the building to make way for an affordable housing project.

  8. Re:Bawstan Habah? on The Evolution of Language · · Score: 1

    languages intrigue me and it sounds silly to me to peg some dialects/accents as inferior to others. Well, the languages or dialects themselves aren't "inferior," they take on identities based on the people who predominantly speak them. E.g., if you have a certain accent or dialect that's mostly spoken by immigrants or laborers without higher education, chances are over time it will develop a reputation as being a low-status marker. Conversely, the pronunciation, dialect, and accent used by cultural elites tends to be regarded as high-status.

    Generally, the language is used as an earmark of education, class, and background; it has very little meaning in the abstract sense. (Actually, I'd argue it has none at all; all languages are inherently arbitrary and none are really superior to any other, except perhaps in terms of technical vocabularies.)

    The difference between non-rhotic accents and the more common 'American English' pronunciations are not wholly dissimilar to the difference between Cockney and Received Pronunciation in the U.K. I suspect there are similar situations in other languages. (In many places there are 'rural accents' that have a definite cultural stigma associated with them, either currently or in the past. I've heard German definitely does.)

    You would have a point if this was an industry where the barriers to entry weren't so astronomically, prohibitively high.

    Telecommunications requires so much capital investment that it tends towards a natural monopoly, at least within regions, dominated by whoever can get there first and run the wires around. Once that first person is there, much of the impetus to repeat the investment is gone.

    Due more to some interesting historical/technological developments than any real forethought, some people happen to actually have two sources of telecommunications, one run by the phone company any one run by the cable TV company. This sort of parallel infrastructure buildout is unlikely to happen again; in fact I think it may actually decrease: one company or the other will decide to expend its resources in areas where the other company isn't, meaning that if you want really good, high speed service, there will be a clear choice even if you have two wires running into your house.

    And really, it doesn't benefit most consumers to have two halfassed networks coming into their house. You're probably only going to be able to easily use one of them (at least one of them, per service, but those services -- TV, phone, data -- are quickly becoming one "packet data" service anyway). Two companies forced to lay parallel infrastructure are always going to have higher costs and worse service than a single company, because of the extra overhead they carry, if (and this is a non-trivial 'if', granted) the single company is forced to offer service at cost, rather than being allowed to increase it.

    Even in minimalist conceptions of government (which I am generally a fan of), there is a legitimate function for the state when it comes to the regulation of natural monopolies. Although I'm not advocating for state-run telcos -- although they may look good on paper, history has shown that state-run industries generally suck terribly -- the way things worked in the U.S. from deregulation to a few years ago (thanks, George!) was that the first carrier to build-out in an area, in return for using the public rights-of-way, had to share the infrastructure with other firms basically at cost, or at low negotiated rates (e.g., "Local Loop Unbundling"). Since this system has been undercut by the telco drones at the FCC, connectivity costs have gone up far in excess of service offered, and competition has diminished.

    I agree.

    Personally, I think Wikipedia suffers from being too limited in scope. Yeah, creating a free encyclopedia is great and all, but I'm not entirely convinced that's what the world really needs. It's good in that it provided some competition to Britannica, and forced them to open up some of their content, but where Wikipedia is most useful is where it goes well beyond any traditional "encyclopedia." Sadly, these tend to be the areas where Wikipedia bureaucrats and administrators are most likely to delete content.

    Wikipedia has the potential to blow away the entire concept of an 'encyclopedia,' but it's held back by narrow-minded ideas of what 'encyclopedic' content is.

    You see this "emulation complex" in a lot of projects. Bottom line: you can never be better than a thing you are trying to imitate.

    Personally, I hate linguistic prescriptivists. I'll use whichever format is less ambiguous; it's stupid to create a rule just for the sake of having a rule, if it produces a stupid result some the time.

    The only good "rule" is to try to be unambiguous wherever possible, unless ambiguity is the desired effect. Simply picking one or the other and then dogmatically sticking to it, even when the result is inferior, is the mark of a small mind.

    I feel the same way about punctuation and quotation marks. I'll include punctuation within quotation marks when the punctuation is part of the quote (when, for example, I'm quoting a statement that really is the end of a sentence), but I think it borders on intellectual dishonesty to insert anything into the quotation marks that wasn't actually in the quoted text, and that includes terminal punctuation. The placement of a full stop can drastically change the tone or meaning of a statement; it's trivial to use American-style quotation rules to perform what's technically not a misquotation but is certainly out of context or misleading.

    Also, when doing technical writing (e.g. documentation), where you are using quotes to distinguish something in an interface from the rest of the body text, including punctuation in the quotes can be confusing. What should be in the quotes is literally what's on the screen, nothing else.

    The American-style quotation rules are a leftover from old typesetting methods that are no longer in use or relevant; it's time that we retired them in favor of greater precision and flexibility for the writer.

They wouldn't do a damn thing, wouldn't include anything in the mainstream tree, etc. The best the guy was ever going to be able to do wasn't a Mac port, it was going to be a Mac fork.

Not necessarily because the TrueCrypt license is bad per se, but just because it's a unique license, and unlike forking a GPL project, which is a more or less routine occurrence, but you'd be using a license that's never been tested, and the original authors of which might decide to use against you.

They pretty much fell over themselves to voluntarily take all sorts of draconian "security" procedures, because they wanted to get into the good graces of the national security establishment.
