    Your professor also seems to have the whole concept of "statistical significance" wrong. A significance level of 0.05 doesn't mean you have "95% confidence" in the results, it means there would be a 5% chance of the observed data being generated if the null hypothesis was true.

    Apologies if I've borked the statistics part of it. Mayhaps I'm referring to a confidence interval, which seems to more closely relate to my (100-x)% recollection.

    The anecdote wasn't intended to demonstrate my m4d sk1llz at statistics, but to demonstrate the ineptness of the prof involved. :-P

    Go to a concert. They make a whole lot more money that way. The percentage they get from CD sales is minimal.

    Not all artists tour near where I live. Almost anyone who is a touring artist doesn't interest me.

    Most of the record labels I listen to primarily do compilations of various forms of house, electronica, and world music. I might be a tad old at a rave and everyone would think I'm a narc. ;-)

    Buying the product is the only direct way I have of supporting them. I'm paying them to sift through a vast amount of music and distill it down to the best -- if I actually buy the CD, the label and the artist at least both get paid. And, importantly, the system that tracks music sales shows that people are listening to their stuff, which at least shows that some of us aren't listening to Britney Spears (or whomever).

    Besides, my CD shelves will hold about 750+ CDs, and I've still got a way to go. :-P

    For me, there's still no substitute for the real CD. I'll rip it myself and decide what I'm going to do with it. YMMV.

  4. Re:More money in death on A Mathematician's Lament — an Indictment of US Math Education · · Score: 1

    By eliminating public education, and by reducing the morass of regulations for running a private school, the free market could decide how important math education really is

    Not really, all you'd do is create a system whereby the wealthier people could afford education for their children, and all of the children of the rest of the people would be screwed.

    How, exactly, do you propose that all of those families who could never afford private school (let alone rent in some cases) educate their children?

    Eliminating all forms of public education sounds utterly absurd. Leaving it up to the "free market" to decide if math education is important or not is equally absurd.

  9. True story .... on A Mathematician's Lament — an Indictment of US Math Education · · Score: 5, Insightful

    In university, I was taking an intro philosophy course on critical reasoning.

    We had covered the concept of statistical significance. The example we'd used was a case of "0.05" meaning we had 95% confidence in the statistical results. On the exam, the professor made a typo, and the question read "how much certainty with a statistical confidence of 0.5", to which the correct answer is 50%.

    I was marked as wrong, and when I complained, the professor indicated that since we'd never covered that example, and only covered 0.05 in class, it was assumed that was what she meant.

    I informed her for someone teaching critical reasoning, she wasn't demonstrating any. I also insisted I get the credit for giving the actual correct answer (which I and everyone who answered it correctly did).

    If that's indicative of how math is taught nowadays, we're all hosed. :-P

    Apple is doing Ok with their iTunes store because they're doing this (though it's still a bit heavy handed with the DRM - I want files I can put on a USB stick and plug it into my car/HiFI).

    I'm sure Apple has absolutely no choice but to keep the DRM as it is. It's the music companies enforcing that. They'd not be able to sell anything at all if they didn't DRM it -- the music companies wouldn't allow that.

    The CD sales model? Not so much. The only people I know who still buy CDs are the ones who aren't handy with a PC. This is doomed business model. Period.

    I must be one of the last people who still buys CDs. Relatively speaking, I buy a lot of CDs -- something like 150+ over the last 3 years.

    I buy the CD because I like to support the artists I'm buying from, and because I like to have the CD. From there I rip it into MP3 format, and use it on my iPod, or make mixes from it, or put them on by GF's iPod, or do whatever I like with it -- and, as far as I'm concerned, that's fair use since I bought the original CD.

    For some of us, the CD is still the preferred method of buying music. It's tangible, you can play it on the trip home from the store (or in your hotel room since I bought a lot of my music when traveling), and if something happens to the 'puter, you can re-rip the tracks.

  13. Re:Who cares? on NSA Email Surveillance Pervasive and Ongoing · · Score: 1

    emails are sent in the clear. If you really cared, you'd encrypt it all. Lots more people than the government have been and will be looking at your email, it's inherent in the nature of the system.

    Telephone messages are sent in the clear too, but it requires a warrant to listen in on them.

    The truth is that almost nothing anyone sends via email is worthy of this furor. Again, anything that you don't want others to see you should have encrypted or sent by other means

    That doesn't give the government blanket privilege to listen in on them. That's going back to saying only those who are guilty have something to hide.

    If one only encrypted the stuff one wanted secret, it would be telegraphing when you're sending something secret.

    The harm comes from noise about things that don't matter, drowning out things that do. Complaining about government intrusion into an inherently public protocol makes it harder to notice instances of true abuse of privacy.

    With all due respect .... horseshit.

    There are constitutional and legal issues which circumscribe what the government can and can't listen in on. Mass reading of e-mail is one of them.

    The harm is the government overstepping their legal authority to monitor the conversations of its citizenry when it knows damned well it can get away with it. By saying "well, gee, why should we care", you're just quietly accepting it.

    And what, do tell, happens when they expand this program to go slightly beyond purely "national security" issues? How about, tracking your political affiliations? Monitoring if you're having an affair? Secretly gay?

    Allowing widespread government intrusion with no rules is just asinine -- especially in a country which still thinks of itself as the "land of the free".

    Dude, they're showing it at an international design show. You know, a bunch of other artists and designers who will think this is cool. I personally thought the lampshades looked really cool -- I'm willing to bet that where these are very unique art pieces, it will be something they can sell for quite a bit if they're willing to part with it.

    Heck, looking at the machine, it's likely not that expensive to make one. It's a frigging metal frame with one big solar panel, some pulleys, and the spindle the resin gets wrapped around.

    They've been in business for over 40 years. Clearly, a measurable percentage of people who aren't you, disagree with you.

    Frankly, this isn't really any different that the whinging between Linux and Windows fanboi's around here. It really all does boil down to personal opinion and experience.

    Nah, Bose doesn't suck so much as you can get similar quality gear for a better price. It's swanky audio gear for people who don't know anything about audio gear.

    Depends on which end of the spectrum you're at.

    At the entry-level end, if you're just talking about speakers in a system, it's just a matter of choice. My four matched Bose 201's and VC-10 centre channel cost neither more nor less than other speakers that were available at the time. To my ear, they sound just fine, and I'd know people whose Bose speakers had lasted decades without any problems. To date (~ 10 yrs), they've performed well and can handle what my Yamaha amp throws at them.

    At the high-end, however, you're absolutely correct -- it's marketed at people who don't want to know much about stereos. They just want to plug it in and never think about it. Those package systems they sell just have less wiring and take up less space than a full component system.

    The reality is, most people don't have super-discriminating ears, and are therefore not really capable of telling much difference between any speakers.

    You're talking about potentially seizing domain from people who also have a right to them. People have a habit of thinking they can extend their trademark into areas of business in which they don't actually conduct business.
