  1. DRM on New Online Music Service For Australia · · Score: 4, Insightful

    I dislike DRM, but I dislike it a whole lot more when its proponents just straight out lie. Quoting the DestraMusic site,

    DRM (Digital Rights Management) is the process in which digital content (audio, video or documents) is securely delivered to consumers over the Internet.

    Bullocks.

    Of course as others have said, the service itself is insulting: $2AU per track for lossily compressed (128mbps!) music that I can't play on my non-Windows computer, or use on my iPod. Thrilling.

    Here at least, the old name was NMR (or NMRI), for Nuclear Magnetic Resonance (Imaging). I used to wonder if MRI was new tech, before discovering it was just a PR move.

    Of course it's completely crazy in the sense that the 'nuclear' refers to the fact that it uses a property of the atomic nucleus, and there are no nuclear reactions to be seen.

    I blame poor science education!

    PS: There's a nice online text discussing NMR/MRI, at least for the lay person like me.

    The devices used by the Russians (eg to power nuclear lighthouses!) were thermal generators, which are about 100000 (10^5) times less efficient than the device being proposed here. Which indeed is a sort of betavoltaic device! So blowing up one of these batteries, while still dangerous, is not nearly as severe, by virtue of it using orders of magnitude less strontium.

    Is there any more information about this on the web? The only link I could find was on rexresearch, which while very interesting, does unfortunately taint it with associations with less plausible technology.

    How much strontium-90 is currently being produced in commerical electricy-generating nuclear reactors? (and how expensive is it to extract?)
    This sort of technology has huge potential, not least of which being that it can be used to extract energy from other alpha- and beta- emitters (ie a fair chunk of nuclear waste.)

    Strontium-90 isn't completely benign (it is a beta source after all, and its one radioactive decay product, Yttrium-90, I think is an even more energetic beta emitter.) It behaves chemically much like calcium, so if it's inhaled or ingested, it can be incorporated into bones, etc.

    On the other hand, I get the impression that it is less dangerous than oven cleaner. You wouldn't eat that either, and like strontium-90, bare skin exposure is ill-advised.

    This idea was also used by Greg Egan in the backdrop of his story "Permutation City", published in 1994. (The first half of the book I really highly recommend. Feel free to stop reading after that though ...)

    In this setting (IIRC), most computer time was up for sale via some bidding system. If you had small problems, sure you could run them locally, but for bigger or more intensive tasks, you'd need to buy time. Computer simulations of actual people, running at about 15% real time, constitute some of these intensive tasks. These simulated people become worried when a project to control the weather, along the lines described above, is initiated and drives up the cost of computing time on the global network.

    That's not the main thrust of the novel though - just part of the scenery!

    1. I believe it is considerably more than 20%.
    2. HECS fees bear little or no proportional relation to the cost of providing the course (e.g. mathematics HECS fee is higher than that of languages, despite the latter requiring much more in the way of resources. Law fees are higher than chemistry, etc.)
    3. HECS payments, unlike income tax, are taken as a percentage of net taxable income, not as a percentage above a threshold. Payments start when the student begins to earn approximately A$25000 pre-tax, where they then must pay a minimum of $750 (3%). This is significantly less than median income in Australia. Often people in this position can't very well afford to start paying HECS.

  7. Re:Statistical Hick-ups... on Longest Physics Lecture in History? · · Score: 1

    I'm not referring to basics, but to deep stuff, honest :)

    I've attended some undergraduate-level courses at a (good) German University, and can honestly say that the pace and workload was much more demanding than the equivalent course in my (also 'good') Univeristy in Australia. This was actually a foreign language course, as regards mathematics I can only judge by the graduates ... Incidently, this particular course did have an associated examination and attendance requirements; failing one or not fulfilling the other would mean that the course could not be counted for credit, or as a prerequisite without special permission.

    So while the system may make abuse very easy, it seems that it is hard to get that qualification at the end of it all without doing some serious work, and learning a lot of material. Perhaps those with no ambition beyond some non-academic employment are finding ways to skimp, but for those pursuing the academic path, the hill is steep and the competition stiff.

    Note from that discussion that the Diplom level qualification is comparable to a Masters degree from a good UK University. It may take them a little longer to complete, but then it is certainly not the case that everyone finishes their undergrad and Masters in the minimum time either. The system completion times aren't so dissimilar as to be terribly worrying.

    Knowing people teaching in the UK system, it seems that the tutorial model described in the web page referenced does not apply generally (though it does to Oxford and Cambridge.) Also, the strict course syllabus has students taking courses they are not interested in, and also makes it very hard for them to get any breadth outside their major. Bored students generally do not make good students.

    If it takes people 6-10 years to get a Masters level education instead of 6-8 as you would expect in the UK, but they come out with a broad and thorough understanding of topics they themselves were motivated to pursue, is this such a bad thing? Judging from the people I've met (and I may just have been lucky) it seems in fact to work very well indeed.

    PS: Students chosing to study are taking a financial loss by not being able to work full-time. Even when there is government assistance, it's not comparable to a full-time job. So it is not as though long term students are making no sacrifices.

    It was my understanding that though it is called a student union, it's not really a union in the same way a trade union is a union.

    Such things as laws against compulsatory unionization and the like don't apply, for this sort of reason. Also (mainly because it's not exactly relevant I guess) they don't set pay awards, etc.

    [...] effectively govt. wants to reduce spending on education and force universities to obtain funding through research avenues AND raise student fees [...]
    which I believe they have done at least twice in the last ten years. But then of course, the best time to kick someone is in fact when they're down.

    The hypocrisy is of course that the ones arguing for these changes are the very ones that benefitted from a well-funded and free university education themselves. Also their arguments about students paying their fair share of costs and the like are completely eroded by the fact that (i) the argument that students get so much financial benefit also implies that they pay so much more tax - doing the sums indicates that graduates (on average of course) already more than payed back the cost of their education before the introduction of HECS; and (ii) the HECS charges are levied differently across courses not based on how much they cost to teach, but on how much they expect graduates to earn on average after graduation.

    Having encountered postgraduate mathematics students and recent postdocs from a number of Western countries, the ones from Germany that I've met have been consistently amazing. The breadth and depth of their mathematical knowledge and understanding is awe inspiring. I can't judge exactly how broad and how deep exactly, 'cause its a lot broader and deeper then my own.

    Correlation not causation etc. etc., but the Universities must be doing something right.

    PS: Australian higher education used to be free. Now it's at partially student funded, but the quality of education (as measured by student-teacher ratios, per-student funding, etc.) has decreased. Note also that it started as a 'small fee' (charging for student services), quickly became partial funding for the whole degree, and then a few years later became even more of a financial burden. If Germany does start charging fees, I can only hope they do not follow a similar road.

    Space Channel 5 (the original) on the Dreamcast was good fun, but suffered from a lack of replayability, was very easy, and too short. It was a game for renting.

    The sequel though just kicked several different types of butt. Much longer, more challenging, much more potential game time, more to collect, more to do, tighter timing ... even better graphics. And it had moments of comic genius - even if you didn't understand Japanese. You could even play co-operatively with a friend! Definitely one of the best games for the Dreamcast.

    I can't believe games like Ikaruga or Soul Calibur II are ported to the GC... (And the fact that SCII on GC outsold the other versions shows that play control simply isn't that important to many gamers.)
    A percentage of people who take SCII seriously, play it with a joystick. In this circumstance, the default GC controller isn't important.

    Don't know how large this percentage is, but it's certainly large enough to make it economically feasible for Hori to make a GC-specific SCII arcade stick.

    For people who have access to both a PS2 and a GC, and who take fighting games seriously enough to use a stick, the only reason to buy the PS2 version over the GC version would be in the situation that they already have an arcade stick for the PS2 and don't want to buy a second for the GC. In every other respect (ignoring console specific characters, blech) the GC port is superior: better graphics, and, most importantly, free of the slowdowns that plague the PS2 version in some stages.

    Society is not something entirely other from the people in it. Supporting society involves supporting the people that compose it -- even the ones you don't know personally, or whose activities (or lack there of) you don't approve of.

    On a pragmatic level, the number of people we're speaking of is proportionally very low. Given that the support you contribute towards them directly is such a tiny proportion of what you are already paying, it seems mean to deny it.

    It's very hard for people to be in a situation where they don't contribute to scoiety at all. They would have to have no friends, no family, and no hobbies that involve others. There may indeed be people who do not contribute in any way at all, but now we're speaking of an extremely small number of people indeed.

    The concept of 'hard-earned money' that is then 'forcibly confiscated' by the government, is an emotive but not especially accurate picture. To say the number of dollars that corresponds to your pre-tax income is 'yours' is to deny that any other party has contributed towards that figure. Given the web of social interactions and public services that we all rely on daily, this is plainly not the case.

    It seems to be a good thing to work to support oneself, in that it gives us purpose and a sense of self-worth, as well as of course providing the necessities of life. But I can't see that this means we must be selfish.

    Note too that the days of high employment are very much likely numbered. Given the outsourcing of jobs overseas, as well as the replacement of unskilled labour by machine labour, it doesn't seem that it will be long before a significant percentage of people will be unable to find traditional-style employment that pays a living wage. What then?

    Having been educated about the food stamp system, I certainly agree that the US situation is not as extreme as those which you allude to.

    Granted, I'm sure there are some people who end up on welfare for extended periods of time for some reason and would rather be supporting themselves, but that's rare.
    Can't speak for the US, but in Australia this is a widely held but inaccurate belief. The majority of long-term unemployed want to get off welfare and support themselves (not least because living on welfare is typically a pretty miserable existence). Yet for whatever reason, the majority of the population seem to believe that most people on benefits for a long period are dole-bludgers. Some are, sure. But they constitute a small minority. It may well be different in the US, given the difference in minimum wage provisions.

It is very important to make a good determination of where the money should be spent.
    Spending money wisely is of course the right thing to do. On the other hand, there are few environmental concerns with the same potential for large scale costs and general disaster - at least that we're facing at present. So even a small risk seems to indicate that concerns about CO2 are warranted.

    The other point is that it's not a static situation: it's (of course) not just a matter of having dumped an excess of some quantity of Co2; but neither is it a case of dealing with a constant rate of excess CO2 introduction into the system. The CO2 emissions are increasing over time, with the growth being more or less exponential. Clearly this can't be sustained indefinitely, as we'll run out of things to burn. But the potential for impact on the environment is much greater than if it were a fixed quanity, or even a fixed rate.

    It seems that the money being spent isn't even reducing CO2 output, but so far (on average), only reducing the growth of that output. Which is abit worrying, really. If it turns out that the risk of climate change through human CO2 emission is significant, just how difficult is it going to be to change our industries?
