  1. Re:How big are the campuses anyways? on Pennsylvania Fracking Law Opens Up Drilling On College Campuses · · Score: 1

    This legislation doesn't appear to apply to Penn State. Despite its name Penn State isn't a state-owned school. It's "state-related", which basically means it gets a lot of state support but is independently controlled. The legislation appears to apply to PASSHE, the collection of true state-owned schools (which are generally smaller teaching colleges). I suspect PASSHE has a lot less land at its disposal than Penn State does.

  2. Re:Counter-intuitive zoom? on FAA Gets a Big-Screen Touch Table · · Score: 1

    Much more likely it's simply because when you pull your fingers apart the system immediately knows WHERE you want to zoom in on -- namely, on whatever location your fingers were initially over. If you wanted to make "moving fingers together" indicate zoom then the system is left guessing which point of the picture you want to zoom in on... presumably it would be whatever point your fingers are converging towards, but that can be hard to estimate accurately (since your two hands might not move at the same speed, or even in a perfectly straight line).

  4. Re:Puzzle quest on PopCap Distressed Over 'CopyCat' Games · · Score: 2, Insightful

    The problem with Puzzle Quest is that the basic head-to-head bejeweled game is far too random. As a result, you spend the early part of the game suffering through that randomness until you get powered up... at which point the game is completely trivial, since you can kill most things in one turn.

    It's a nice concept, but it needs some serious tweaking.

  5. Um.... duh? on PowerPoint Bad For Learning · · Score: 1

    Speaking on behalf of math instructors, there's a reason we use chalkboards.

    Pacing.

    Writing out your points as you make them forces you to slow down your exposition. This makes it easier for your audience to digest what you're saying, and also gives them time to take notes. Using premade slides or a powerpoint slideshow lets the presenter run unchecked, and the audience tends to zone out rather quickly. I could cover three times the material in a lecture if I used premade slides, but my students would get so little out of it that I might as well have said nothing at all.

    Quinine is not expensive. Well, that's debateable, but irrelevant. Quinine is not a viable long-term malaria preventative. It requires daily doses and has common side-effects of varying degrees of unpleasantness.
  7. Re:graphing calculators on More Videogames, Fewer Books at Some Schools? · · Score: 2, Insightful

    Why are grade-schoolers expected to buy calculators? Beats the bejesus out of me.

    I've taught undergraduate mathematics going on ten years now, and for the vast majority of the courses (including calc, vector calc, diff eq and linear algebra) my students aren't permitted calculators on either quizzes or exams.

    Calculators are a crutch. They teach students to shove numbers into a magic box and just accept whatever comes out. In a perfect world that wouldn't be the case, but until the students have a solid grasp of the material it's far too tempting for them to just memorize some calculator mojo in order to get by.

  8. Re:did it really "erase" memory? on Drug Selectively Removes Rats' Memory · · Score: 3, Informative

    the rats didn't fear the note they heard while drugged The rats didn't hear anything while drugged. The experiment goes
    1. The rats hear tone 1 and suffer pain.
    2. The rats are (or are not) given a drug.
    3. Time passes...
    4. The rats hear tone 2 and suffer pain.
    The rats that are drugged then have no association of pain with the FIRST tone. So even if you think the drug was around to affect them for the second tone, that's not the tone that's "forgotten" -- both sets of rats have fears with the second tone.

    The whole point is that the drug removes the association with the first tone AFTER the fact.

    Written Notice and Authorization.
    Before you can get a consumer report for employment purposes, you must notify the individual in writing -- in a document consisting solely of this notice -- that a report may be used. You also must get the person's written authorization before you ask a CRA for the report. (Special procedures apply to the trucking industry.)
  11. Re:Nobody liked Final Fantasy 3 DS? on Slashdot's Games of the Year · · Score: 1

    The save system is... mostly tolerable. You can save whenever you are on the world map; since most of the dungeons are relatively short this generally isn't a problem.

    Unfortunately the final dungeon of the game is a massive exception -- the first time through you could spend anywhere up to 2 hours (depending on how much time you spend looking around for secret areas) getting to the final boss, at which point you will almost certainly wipe and face the prospect of doing it all over again.

  12. Re:Having lived in both Germany and the US on Life Without Traffic Signs · · Score: 1

    As a former resident of PA, I have to agree with the parent. Pennsylvania most definitely has laws regarding right-of-way, they just aren't necessarily phrased that way. I mean, just about every written PA Driver's exam I've seen asks about right-of-way at an all-way stop (when two or more cars arrive at an intersection simultaneously, the rightmost has right-of-way). You also have to yield right-of-way to pedestrians in the road whether there is a crosswalk or not (the fact that they're jaywalking does not make it legal to run 'em down; when I was in PA a busdriver was almost prosecuted for manslaughter for hitting a jaywalker -- the only thing that spared him was eyewitness testimony that basically indicated the victim had stepped from the curve directly into the bus). And on and on...

    The fact that someone could have driven around Pennsylvania believing there is no concept of right-of-way is actually kinda scary. There may be multitude of PA drivers who blatantly ignore the law regarding right-of-way, but they at least realize they're doing it.

  13. Re:Oblivion-like substances just don't excite me on Oblivion Confirmed for PS3 Launch · · Score: 1

    The only reason Oblivion ever gets hard is because of the idiotic monster-levelling. Focus all your efforts on raising _just_ two skills (one offensive, one defensive) and the game is ridiculously easy. The only point in raising other skills is to make the game harder : when you level, so do the monsters, and unless your skill-ups have been of the kill-stuff variety they can rapidly outstrip you. (At one point I literally spent 10 straight minutes wailing on a zombie before it died because I foolishly spent my time raising non-weapon skills. And don't even think about fighting trolls if you're behind the curve... they'll regenerate faster than you can hurt them.) How Bethesda managed to take the twink-happy Morrowind character system and make it even worse is beyond me.

    Another tip is to _never_ do your level-ups in batches. This will just cause all the monsters to suddenly become much more powerful, while you'll be stuck fighting them with substandard gear.

    Anyway, if you don't gimp yourself the guys in the gates are easy. When they didn't run away I probably cut most of them down in 3-5 seconds apiece. Storm atronarchs, dremora, whatever... whack whack whack dead. Quickly became an exercise in monotony.

Every time Comcast calls up to try and sell me VOIP service, I just laugh at them and say "I like my phone to actually work, but I'll be sure to contact you if that ever changes."

  16. Re:RMS's Emacs tapes on GPL Causing Problems for Derivative Linux Distros · · Score: 1

    RMS could get away with that because the tapes were the only means of getting emacs from him.

    Under the GPL you can charge all you want for the software, and as long as you provide the source code at the same time your obligation is over. So if someone went up to RMS asking for the emacs code, either (1) they had previously received the source (on a tape) from RMS or (2) they had never received either source or binaries from RMS. Regardless the GPL imposes no responsibility on RMS to provide anything in those cases, and so he is free to charge whatever he wants for a copy of the source -- or even refuse to give them anything. In short, the price he charged was not the "cost of physically performing source distribution" mandated by the GPL because the terms of the GPL were not in effect.

    To reiterate: As long as you provide the source when you sell the software (for however much you care to charge), you NEVER need to respond to requests for the source.

    Mind you, nothing in the GPL stops anyone who bought the source from putting it online or otherwise distributing it themselves, but if they choose to put binaries online it's then their responsibility to make the source available (though not necessarily online) to anyone who asks for it. This possibility didn't really cause too much of a revenue problem for RMS because (1) people wanted to support him, and (2) network access was much more limited at the time.

  17. Which Core Duo processors? on MacWorld Keynote Announces x86 iMac & Laptop · · Score: 1

    I must admit I'm not terribly familiar with the various Core Duo processors, but from looking over the specs at Apple and comparing to Intel's Core Duo specs it looks like the MacBooks are using the T2400 (for the 1.83 MHz) and L2400 (or L2300, for the 1.66 MHz).

    I mention this because it was also my understanding that Core Duo T's seem to be the desktop line.

    Anyone have any more info on which processors are actually going to be used in the MacBooks, and whether a Core Duo T might present an issue with respect to heat and power use? (Not that my Powerbook G4 gets anything better than mediocre battery life.)

  19. Re:equals on Scientists Define Murphy's Law · · Score: 1

    Nope. Seriously. Real world triangles (usually) don't have angles which add up to 180 degrees. Ask any competent mathematician -- like me (at least, I like to think I'm competent). Ask any physicist who knows general relativity.

    In hyperbolic geometry (which has all the axioms of euclidean geometry except for the parallel postulate) a full rotation is still 360 degrees, but the sum of the angles in a triangle is less than 180 degrees -- in fact, what the sum is actually depends on the area of the triangle.

    The problem you're having is that you're assuming that the notion of 'perfectly straight lines' is somehow obvious -- it's not. By any sensible criteria the lines in hyperbolic geometry are perfectly straight -- they give the shortest path between two points, etc -- and yet given a line L and a point P not on L there are infinite number of lines through P which don't intersect L. All this even though it seems obvious that it couldn't ever happen.

  20. Re:equals on Scientists Define Murphy's Law · · Score: 5, Insightful

    Those axioms are observations.


    No, those axioms are just the assumptions that a mathematician made. They don't have anything to do with reality, or the things we observe there. Every theorem has hypotheses and a conclusion; writing every one of those hypotheses every time you make a statement gets old, so you declare some things to be true before you get started.


    One important observation, one of two axioms underpinning all of math (and therefore science), is "consistency". The other is falsifiability, that only statements that can be proven false are scientific - the rest are metaphysical.


    The notion of consistency that troubles logicians is a matter of axioms -- it is merely a matter of whether there is a statement such that it and its negation follow from the axioms. Nothing to do with reality. As for "falsifiability", that has absolutely nothing to do with mathematics. Things are proven to be absolutely true in mathematics all the time.


    Math such as "all triangles are composed of three interior angles totaling 180 degrees" is an observation.


    No.

    I feel I must repeat: No.

    That the sum of the angles in a triangle is 180 degrees is a consequence of the axioms. It is most definitely not an observation, since it isn't actually true in the real world (though it is very close to what you might measure).

    The statement about angles is a consequence of Euclidean geometry. Work in a different geometry (ie non-flat, like spherical or hyperbolic geometry) and the formula for the sum of the angles is very different.
