  1. Re:Algebra test on Algebra As A Gateway Subject · · Score: 2

    You can't, because it's a falsifiable statement.

    a=-1
    b=-1

    LHS:
    2^-1 = 0.5
    3^-1 = 0.33333...

    Sum:
    0.833333.... (5/6)

    RHS:
    5*a*b =
    5*-1*-1 =
    5

    which is greater than 5/6. If you can prove 5/6 >= 5, then you've either got different definitions of those numbers, or you've got an inconsistent proving system that lets you derive a contradiction.

    Unless they're very motivated, or the teachers drop the idea of grading on gentler curves and start to fail people en masse (which isn't the best way to endear themselves to parents or angry school board members), I think a fair number of students would try to coast by with minimal effort.

    Heh. I did once have a college course with no homework, no project, and few exams -- most of the classes consisted of an open, earnest discussion on sociology / polisci studies. Something like 30-40% of the course grade came down to /one/ essay question in the final. ;)

    While some "America is getting STOOOOOPID" studies have pointed to early exams as having nastier questions, they often ignore the question of selectivity. If we only looked at the cream of the crop now (as did some early snapshots), they're still doing pretty darn well.

    Good for you. The problem-solving skills are fundamental, but you can usually look up Greene's theorem or Runge-Kutta differentiation or Simpson's rule and its ilk for numerical integration or what-have-you if you need them.

    Since it opens the door to mathematical logic, proving techniques, and a domain where people /must/ be able to reason to do well, I'm all for teaching algebra to everybody.

    - They may not realize how much they're screwed if they maintain a high credit card debt, and only make minimum monthly payments -- or, in general, how much borrowing money can really cost them.

    - They may not understand what their politicians blather about when discussing economics.

    - They may have no clue as to why the lottery is a /bad/ investment, unless it's a HUGE jackpot and everybody else is staying home due to CNN claiming a massive outbreak of West Nile and gigantic man-eating snakehead fish. ;)

    And so forth. Mathematical reasoning -- and, for that matter, a class on rhetoric, lying plausibly, and common fraud techniques (to innoculate people against smoke and mirrors) would prove quite useful to people, I'd think.

    Quote from the article:


    The DMCA is both an egregious law and a brazen power grab by Hollywood, the music industry and software companies. It is probably unconstitutional. It creates unnecessary federal crimes, cedes too much authority to copyright holders, and should be unceremoniously tossed out by the courts. (As a bonus, perhaps we could horsewhip its many fans in Congress.


    Now, in case you're too ignorant to know what "egregious", "unconstitutional", and "brazen power grab" mean, I'll simplify by noting that Declan is calling the DMCA a really really bad law.

    If a "researcher" focused solely on, say, empirical analysis of decryption technology with respect to e-commerce, and in the name of research provided programs for breaking into Amazon.com, Ebay and Yahoo!, I suspect that the DMCA would apply.

    He was a principal player of an enterprise engaging in commercial activity that was criminalized in the US, and that impacted a US company -- Adobe. Despite that, he entered the country voluntarily and demonstrated this activity. According to a DOJ press release, he is also the copyright holder on his program, so any distribution should be going on only with his full consent -- which is likely given the nature of his presentation.

    The program was also purchasable from within the United States from an Elcomsoft.com server hosted in Chicago (again, within the US...). Payment was handled through an online service located with the United States.

    So, he was willingly distributing an illegal circumvention device within the United States, to Americans.

    1- A hell of a lot more funding, plus more stringent competency requirements, for public defenders. (Are their public defenders for civil suits? I doubt it -- the Bill of Rights "you have a right to an attorney" clause probably only covers criminal cases -- but perhaps there should be.) Defense attorneys often get criticized for defending people who are probably guilty, but the alternative is having a judicial system with a rubber stamp.

    2- Loser pays "reasonable" legal expenses, perhaps to be specified in statute (e.g. hire Johnny Cochran to beat a traffic ticket if you like, but don't expect the state to foot the bill), possibly subject to an "ability to pay" rule.

    3- Harsher sanctions against barratry.

    4- The full text of laws /must/ be freely available to the public, at minimal production/delivery cost -- none of that "we copyrighted the Code and you'll have to pay to see it" bullshit.

    Hmmm. It might be that a lot of customers just don't care about 10K RPM (do many even ask what speeds the drives are?), or about SCSI); again, do the masses care about whether or not multiple SCSI drives running simultaneously on the same controller do better than trying simultaneous accesses to multiple IDE drives on the same channel?

    I suspect that most home users care primarily about one thing about drives: capacity, for all those pictures / videos / games / MP3s / et al. Noise might be another concern if it's terribly loud, and size (I'd guess that some might blink at a full-height drive, now that there are so many big, cheap, single-height IDE drives). But RPMs?

    And if SCSI is only sold in low quantities, or to entities that can pay top dollar, then the prices /might/ be reasonable from a "we've still got to pay overhead and the factory costs the same even if we pump out few drives" point of view.

    It's probably the same situation as with tape drives (IDE ones aren't TOO outrageous, but SCSI tapes of modern, non-trivial capacity are very, very expensive) -- it's probably worse there, in that many home users probably never even consider getting a tape drive for backing up.

    First -- what specific, bogus claims has Intel made about P4 performance? A literalist might suggest that Intel claims that P4's help game performance in alien spacecraft, but that's a little hard to falsify, as far as I know, and probably wouldn't fly (unless, say, the plaintiffs include a bona fide literally minded extra-terrestial of the Roswellus anthroabductus variety).

    Second -- it's a generally established principle ("puffery") that commercials are allowed to exaggerate to some degree. Chevy can claim that their vehicles are tough, "like a rock", which is a far less specific claim than, say, "this product is so tough that it can be driven two hundred thousand miles without maintenance" or "its windows will withstand sustained 9x19mm fire: perfect for the urban gangland outing". "Making the internet run faster" /might/ be considered puffery as it's a fairly vapid claim (does "the internet" include, say, running the Flash / Shockwave / Java applets that abound online?).

    If they /have/ been making specific, non-puffery, bogus claims however, then I wouldn't mind seeing them smacked around for it, so long as the same reasoning gets applied in other cases as well.
