    Wrong. Its still precedent. Every where. Until another circuit rules differently it is still essentially the law of the land.

    Let me slightly amend my original statement. It is not binding precedent except in the original circuit. It is persuasive precedent, but that and three bucks will get you a cup of coffee at Starbucks.

    Different rulings in different circuits are a rarity in US jurisprudence, and they are virtually never are allowed to stand. They are strictly temporal anomalies.

    Not since the Reagan administration, when SCOTUS review became almost entirely discretionary. These days, the SCOTUS frequently rejects cert on cases with significant conflicts between circuits. They only have time to review a few dozen cases per year, and as a result, it is not at all uncommon for conflicts of interpretation to persist for many, many years.

    Also, different rulings in different circuits are remarkably common these days, particularly when you have ridiculously oversized circuits like the 9th that half the time don't even agree with themselves.... :-D

    *shrugs* I work in high tech, and although I know calculus, I can't say I've used it... well, ever, at least not since I took the class. Calculus is certainly important in certain narrow fields relating to materials science, aerospace, etc., but it doesn't have a lot of practical use as a general tool. (Quick, when's the last time you needed to calculate the area under a curve?)

    On the other hand, I use statistics frequently as a fundamental part of my understanding of the world around me. Every day, I curse the public's lack of understanding of basic statistics. When people panic in fear of relatively rare events while doing nothing to prevent common problems that kill people on a daily basis, I grow concerned. When products get banned because of a couple of deaths over several years, while the news media decries those products as death traps even though more people die annually from drinking too much water, I grow concerned. And so on.

    What I'd like to see is less time spent on basic math during the first few years. When you really get right down to it, we have calculators and computers for that. Being able to successfully add, subtract, multiply, and divide four-digit numbers is no longer a particularly useful skill. Instead, we should spend only a year or two explaining all of the basic concepts of addition, subtraction, multiplication, division, and fractions sufficiently for kids to understand what's happening at a crude level, then move on to more useful, high-level math like algebra, statistics, geometry, calculus, etc. By wasting so much time on the tedious basics (which half of them will never use again once they get their hands on their first calculator), kids get turned off to mathematics before they even get into the good stuff. Addition, subtraction, multiplication, and division simply cannot ever be anything but drudgery. Statistics, on the other hand, is actually moderately enjoyable. Can you imagine how much more fun it would be if the Skittle color statistic stuff was taught in first or second grade instead of high school? And once you're teaching statistics in elementary school, then moving on to teach trig in 8th grade and calculus in 9th grade is a no-brainer.

    Then again, I'm of the opinion that by first grade, every student should be exposed to abstract concepts like variables, whether in programming classes or in algebra. (And yes, I learned to program on my own at that age with a series of training tapes. Most kids can, honestly.) Abstract thought, like language skills, is something that must be learned while the brain is still forming. By high school, it's too late to pick up those skills, and if you don't have them, you'll barely make it through algebra. Many people never do, and IMO this is at least in part caused by teachers spending all of the critical first two years of education teaching kids to color the horse black or brown, teaching them how to count coins, and other relatively concrete concepts instead of exposing them to things like music, computer programming, abstract mathematics, and other tasks that require higher-order thought.

    This is not to say that you should really teach statistics, algebra, trig, and calculus to first graders; they're not really ready to fully grasp the concepts yet. Instead, you should expose them to the concepts early and often, presenting the same concepts with varying levels of complexity and in different ways, knowing that they'll pick up more and more of those abstract concepts as they get older. The important part is to lay the groundwork. In much the same way, kids can pick up the tedious grunt work like addition and subtraction a little bit at a time, spread over the course of their entire K-12 career instead of having it all shoveled in at the front.

    Of course, such an approach pretty much requires throwing away the book on how teaching is done. You can't evaluate kids on their skills if your primary goal is laying the groundwork for those skills rather than teaching them entirely. You have

    The problem is that, as the market shows, most people neither need nor want gigabit or even 100meg. even 50/20 is more than most people will ever use.

    No, the market does not show that. The market shows that most people are unwilling to pay more than the base price for Internet service, period, regardless of what the base service provides. Using those same standards, fifteen years ago, you would probably have said that 56 kilobit is more than most people will ever use, simply because nobody was willing to pay through the nose for ISDN.

    The fact of the matter is that only a tiny fraction of people have service over a couple of megabits per second. Therefore, there is no market for content encoded at a higher rate or services that would require a higher rate. Therefore, there are no services that require a higher rate. History has consistently shown that as average service speeds increase, the need for bandwidth increases to match. Any argument that any given amount of bandwidth is more than most people will ever use is absurd, because it assumes a stagnant industry that does not exist and never has.

    Part of living in the real world is prioritizing how you spend your limited resources, and generally its better to address needs that you have NOW rather than addressing potential future needs.

    Part of living in the real world is anticipating future needs and prioritizing them when it is potentially beneficial. For example, those cities and towns that get high-speed fiber everywhere are going to draw in the sorts of high-tech people who drive innovation. Businesses that need those sorts of people are going to locate there because of that advantage. This will result in higher property values, more tax revenue, better schools, and a better standard of living even for people who don't care about those networks.

    I can easily think of lots of general-purpose uses for gigabit connections. They mostly involve removing the need for local storage of everything. Right now, it isn't practical to just shove your movies, applications, etc. up into the cloud, because the performance is 1–2 orders of magnitude slower than your local hard drive (in the best case scenario). With gigabit, that bottleneck goes away. It would also enable 3D Blu-Ray quality streaming video over gigabit fiber (64 Mbps peak data rate). Heck, 3D Blu-Ray quality videoconferencing would become feasible at that point.

    That said, probably the biggest reason for moving to gigabit fiber has nothing to do with gigabit and everything to do with replacing the aging copper infrastructure that Internet service currently depends on. DSL is crap. It provides service only near the CO or specially equipped RTs, it runs over aging pairs, many of which are in sad shape and get crosstalk every time it rains, etc. And cable modems have signal strength problems from aging lines, seriously limited bandwidth that's shared among everyone on your local loop and seriously limits what can be done in terms of things like VOD, etc.

    Fiber has none of those problems. It is a next-generation infrastructure that will be robust for decades, replacing one that breaks down constantly. The long-term cost of continuing to maintain a legacy copper network will eventually be more expensive than the cost of building out a modern fiber network. The only real question is where the tipping point is.

    The literacy standards reduce the amount of fiction being read substantially, and non-fiction reading becomes emphasized.

    No, the literacy standards are intended to increase the amount of nonfiction by adding additional reading in non-English classes. The standards are not intended to reduce the amount of fiction at all, and if that's happening, you're doing it wrong.

    I think it's a reall good thing--we currently do a poor job of preparing our students for the myriad of technical text they will have to interact with as a person and a professional.

    The reality, though, is that technical texts are inherently uninteresting. I spend 40 hours a day writing technical texts, and I wouldn't recommend them to anyone unless you need to understand that particular subject. There's no such thing as a general-interest technical text that would be useful, accessible, and interesting to an average high school student, because different students have different interests and technical backgrounds. Technical texts really have no place in a high school curriculum except as part of a technical class. High school students should read technical texts in computer classes. They should read them in woodworking classes. They should read them in science classes. They should not read them in English classes.

    The purpose of English classes is to teach the English language. Technical texts do not do that. Except for subject-specific terminology, we write at about a third-grade reading level. The sentence structure is fairly rigid, the word choice is very basic, and the sentences are kept very short. We use bullet points to simplify parsing of anything longer than about ten words. In short, technical texts are designed around precision and concision, which is to say that they use as little English as humanly possible while still conveying the point. Therefore, using such material in an English class would actively harm students' vocabulary, sentence structure, grammar, etc. because all those things pretty much go out the window in a technical text, in favor of absolute simplicity.

    And students really are fairly well prepared for reading technical texts. Reading the texts, assuming they are written properly, is remarkably easy. What students lack is the vocabulary in any specific discipline. However, they can't usefully get that in high school because high school is not a specialized, single-career-track program. That's what college is for. Having all the students in an English class read some technical report about bird habitats or whatever isn't particularly useful to them in a career unless they plan to go into an environmental studies field. Having them all read a computer programming book isn't useful unless they plan to go into programming. The notion that high school can somehow prepare students for the technical parts of a college curriculum is prima facie absurd.

    What high school can and should do is require students to write more. Requiring research papers in science and history classes is a great way to do this. It teaches students how to read technical texts for comprehension, but allows students the flexibility to choose a subject that interests them. It forces students to write, so even though the texts they are reading don't really improve their vocabulary (except in a subject-specific area), it encourages them to use their vocabulary while writing, which inherently strengthens it.

  7. Re:Already being done. on Politician Wants Sci-fi To Be Mandatory In School · · Score: 1

    Teaching nonfiction in English classes is not the manner in which the Common Core was intended to be implemented. The intent was for science and history teachers to increase the nonfiction reading in their classes. Unfortunately, lots of schools are doing it wrong.

    This is particularly disturbing because reading nonfiction in English classes is pretty much an utter waste of time. The purpose of English classes is to learn about the language. Nonfiction books don't use the language. They're almost invariably either academic in tone (which is just dreadfully boring unless you happen to be interested in that particular topic, and will only further the disenchantment that the youth of today feel towards reading) or technical in tone (which is even worse). Neither one is likely to expand vocabulary, excite students, force students to think, or basically do anything else that a classroom is supposed to do.

    Nonfiction reading in a history or science class, however, facilitates learning about a particular subject in history. Assuming students have some freedom to choose texts that interest them, such reading has the potential to enhance the learning process.

    For this reason, it is crucial that teachers and parents loudly shout, "No!" when school administrators try to implement the Common Core by shoehorning nonfiction reading into the English classroom. That's the wrong way to implement the standard, and any district that tries to do it that way is in desperate need of a change in leadership.

    The bombers were taken because of footage from cameras, most of which were owned by private individuals. Those cameras don't have the same privacy concerns as government-owned cameras because no single entity has access to all of them except under extreme circumstances where everyone universally agrees to make that footage available. And this is the way that it should continue to be done. This bombing provides no justification for any changes whatsoever. The system, as designed, with privacy built in, mostly worked.

    Incidentally, to the extent that the system did not completely work, it failed in a way that more cameras—particularly publicly accessible cameras—would exacerbate. If the public had access to more cameras, more often, we would have more incidences of false accusations like the one that led to the (presumed) suicide of Sunil Tripathi. The whole reason for limiting access to video from lots of different sources is that it greatly increases the probability of misidentification by greatly increasing the perceived confidence in the evidence (regardles of whether the public or police are doing that identification). Thus, the Boston bombing incident plainly demonstrates why the use of video evidence as a starting point, in the absence of other evidence tying someone to a crime, is an extreme solution that should be used only in extreme circumstances, where there is a serious public safety concern. Based on what happened here, IMO, giving the police access to more cameras more often is only likely to ruin a lot of innocent people's lives.
