  3. Re:Where do you live? on US College Students Still Aren't All That Interested In Computer Science · · Score: 1

    This is slightly off-topic, but 4-6 hours of homework every night for a college student doesn't seem that far outside the realm of reasonable to me. A student taking 12-15 semester credit hours is considered a full-time student. The thinking is that this course load represents the same commitment as a full-time job, i.e. about 40 hours per week. Since each semester credit hour represents an single hour of class each week, a 12-15 hour load represents only 12-15 hours of the student's commitment for the week. That leaves another 25-28 hours for homework. That's another 3.5-4 hours for homework every day, or 5-6 hours if you take the weekend off.

  5. Re:This has little to do with copyright law on $200 For a Bound Textbook That You Can't Keep? · · Score: 1

    With regard to sales tax, it may also be appropriate to note that no sales tax need be paid on many textbooks. Most public universities operate their own bookstores (either directly, or through some intermediary), and in many places these university run bookstores, as extensions of the state, do not charge sales tax. This probably varies some from state-to-state, and almost certainly does not apply to private institutions, but does deflate the tax argument a bit more.

  6. Re:This has little to do with copyright law on $200 For a Bound Textbook That You Can't Keep? · · Score: 2

    It should also be noted that, from a student perspective, this is likely very similar to what already happens. Most students seem to sell their textbooks back to the bookstore (or some other reseller) at the end of the semester (much to the chagrin of a calculus student that showed up in one of my second semester classes---he sold his book back to the bookstore in December, then had to rebuy it in January, since he needed it for my class). Since they get a pittance for their books under such an arrangement, a $200 textbook that is bought then resold vs "rented" wouldn't make that much difference. The model of renting books to students doesn't seem terrible to me at first blush.

    Of course, the real problem is that textbooks cost $200 in the first place, and there is no good reason to be charging students $200 for a rental.

  7. And one more note. If your university class has required attendance to lectures you are not in a uni, but in a daycare for grownups. It should be about learning, not about sitting on your ass in some specific spot at some specific time.

    I know of no university in the world that can compel you to attend class. You are always free to attend or not. When a professor states that attendance is required, the strongest statement that they could possibly be making is that attendance will constitute a (possibly very large) portion of your grade. There are some classes where attendance really is important (seminar classes where there is a lot of give and take between students and the instructor; practical classes like chemistry labs; and so on), and in such a class a professor may be making that point. In other cases, the professor might note that attendance and performance on assessments are highly correlated, and "require" attendance in an effort to improve overall performance. In either case, you are free to attend or not, as you choose.

    While the headline makes a sweeping statement, the research is statistical in nature. Essentially, if you are an average student (I don't know how they selected or segregated their sample, but one assumes that they outline their methodology in the paper---my institution does not subscribe to [i]Psychological Science[/i], so all I can see is the abstract), you are more likely to do well if you take notes longhand rather than with a computer. In terms of your anecdotal evidence, the study is mute, as it doesn't seem to consider any kind of disability, nor does it address those that take no notes.

    *headdesk*

    Man, I wish that all of my students were as smart as you. I assign them reading from the text prior to lecture, and give them problem sets to work on ahead of time. I encourage them every day to do the work before class (the reading and exercises). And then on my evaluations I get dinged for assigning problems that the students don't know how to do, because we haven't covered them in lecture yet. THAT WAS THE POINT!

    The headdesk, by the way, is not for you, but for my students.

    Affirmative action was established by Executive Order 10925, which focusses on data collection. Executive Order 11246 supplanted this order (note that this order has been amended somewhat, but the link on EEOC's website seems to be dead, and I don't have the interest to find the most recent version---it is not necessary to counter your point, and if you really care, you can probably find it yourself). Again, note the emphasis on collecting data regarding existing discrimination, and the lack of any order to conduct "positive discrimination."

    The original intent of affirmative action was not to set quotas (and, in fact, quota systems have consistently been struck down, as have strict point-based systems). The original intent was to level the playing field by explicitly disallowing employers and educators from removing people from the candidate pool on the basis of race (and later sex), and to encourage those employers and educators to recruit people from minority, historically disadvantaged groups into the candidate pool (for instance, sending college recruiters to high schools that are majority black in addition to all of the places that they would normally go). Please read the original executive order and tell me where you see quotas mentioned.

  14. Re:Vaccines on The US Public's Erratic Acceptance of Science · · Score: 5, Insightful

    I'm not entirely sure what your point is supposed to be. If your definition of safe is "completely devoid of any possibility of risk," then I wonder how you justify getting out of bed every morning. A more reasonable argument is that safety is always a relative measure. Injuries attributable to common vaccines are uncommon, permanent damage is incredibly rare, and death occurs at a frequency that can best be described as vanishingly small. On the other hand, many of the diseases that we vaccinate against often cause permanent damage or death, and weakening the herd immunity puts not only the individual at risk, but society at large. So, yes, there are some potential (though very small) risks to vaccination, but that does not mean that they are unsafe.

There are numerous examples of physicians supporting creationism as science, engineers claiming expertise on mental illness, and (yes) English majors pontificating on mathematics.

    Man, that second sentence is awkward. I should have edited.

    Suppose that there exists a configuration of N pulleys. To this configuration, we add an additional pulley. The two pulleys that are nearest to this new pulley are separated from the new pulley by a segment of conveyor that runs between two additional pulleys that are (potentially) quite distant. This configuration provides a counter example to the induction suggested above.

    The paper that they cite is not in English (Abellanas, "Conectando puntos: poligonizaciones y otros problemas relacionados"), so I am not sure that I even really understand what the statement of the problem is. That being said, I don't think that the induction works out the way you want it too. Consider, for example, a situation in which you add a new pulley to an existing configuration and the two nearest neighbors are separated from the pully added by induction by a stretch of conveyor belt that runs between two pulleys that are very far away from the three-pulley configuration under consideration. I don't think that you can actually do the induction on the number of pulleys, as the configuration of the pulleys in addition to the number of pulleys.

  20. Re:Pedantic Man to the rescue! on How Does Heartbleed Alter the 'Open Source Is Safer' Discussion? · · Score: 2

    Except that the argument wasn't really "potentially vulnerable to attack" is not the same as "compromised" (though it is certainly easy to see how one could come to that conclusion by ignoring the context---and maybe I am misinterpreting the parent, as well), the argument was that all (but only) SSL sessions using the newer versions of OpenSSL were/are vulnerable (i.e. compromised), and that by virtue of not every server in the world automatically being updated to these newer versions, the statement "every SSL session is compromised" was hyperbole.

    One should also note that while the dictionary definition of "compromised" is essentially identical to "vulnerable," there are nuances of meaning in the way in which the two words are used. I would suspect that most people would regard something being "compromised" as more severe than something being "vulnerable." In fact, your example of science fiction seems to make my argument for me. You aren't really disagreeing with the parent, only nitpicking semantics (unless you really do believe that "every SSL session has been compromised," in which case there is a bigger problem with SSL than Heartbleed). If you are going to argue the point (viz: "compromised" and "vulnerable" are synonyms without distinction), why don't you explain what it means to "decimate" something, and how too many people seem to use the word incorrectly.

    One compromise that I like is slides for complicated figures (that would take forever for you to draw, poorly, on the board) and handouts of those slides so that the students don't have to try to recreate them (again, poorly).

    Indeed. I would even go so far as to say that this is not a compromise, but the actual, honest-to-goodness, correct use of slides in a presentation, and has been since the dawn of the slide projector. Complicated figures, photographs (of, say, an archaeological excavation or Civil War soldier), or the hypotheses of a theorem that you are planning to prove on the board are reasonable things to put on a slide, and are things that should be put up on the screen for reference. Lacking a projector, handouts are a good alternative (and, perhaps, might be preferable, except for the time that it takes to pass them out and the fact that most of them will end up on the trash).
