  1. Re:why papers on Cheating Made Easy · · Score: 1
    Maybe I don't understand but why would someone take a class where they had to right a paper on Joyce? What purpose would the paper have?

    You seem to believe that the purpose of education is to enable the student to get a good job and earn more money.

    For some people, that is not the main purpose of education. Some people take courses about writers like James Joyce because they are interested in the work of writers like James Joyce. Naturally, they are then happy to write papers about what they have read because these lead to feedback from a teacher, and further understanding of Joyce's work.

    In some universities, particularly in the USA, students who want to study (for example) chemistry or computer science are compelled to take courses about subjects in which they have no interest, in the name of a "rounded education" or some such concept. In my view, this has nothing to do with education. Nobody can really teach you to appreciate James Joyce, or Jane Austen; or to understand quantum mechanics or relativity (I happen to be a physicist). All a good teacher can do is guide you in the path of study, and provide feedback to clear up misconceptions or explain difficult points. The thinking and the studying can only be done by the student.

    Of course, these comments apply only to university-level education. At a more elementary level (the level at which one learns the difference between the words "right" and "write", for example), the student lacks the maturity to make sensible choices.

  2. This nonsense has been around before on Hackers As Factory Workers? · · Score: 4, Insightful

    The "software factory" analogy has been around before. It's nonsense, of course. The software analogy of a "factory" is the plant that presses CD-ROMs. Pressing the 10,000th CD-ROM of a software product is the software equivalent of building the 10,000th Nissan Maxima on a production line.
    But writing the software which will go on that CD-ROM is the software analogy of designing the 2005 model of the Nissan Maxima. Now, some software development is not very creative. Just as tweaking the design of a car model that's been around for 10 years, to get something a little bit new for a new model year, is not very creative mech engineering. But it's still design, not assembly-line production. A competent software engineer will be able to do it better and faster than a bad one. And a factory worker will not be able to do it at all.

    There is no such thing as an "international patent".

    There is a procedure called an "International Patent Application", governed by a treaty called the Patent Cooperation Treaty, but it's just a way of applying for a bunch of national patents at once. The national patent offices still apply their own rules, both to the application and to what they grant (Article 27 para 5 of the treaty says: "Nothing in this Treaty and the Regulations is intended to be construed as prescribing anything that would limit the freedom of each Contracting State to prescribe such substantive conditions of patentability as it desires.").

    That comment is a joke. There is no such thing as "MS Office formats". There are as many de-facto Word formats as there are versions of Word, and as many Excel formats as there are versions of Excel. Moreover, if you want to know exactly what these formats are, the best source I know of isn't Microsoft, it's OpenOffice.

    The real reason LM will not run OpenOffice is that their MS Office users will not want to change from what they know, and there are plenty of little problems with OO that they can use as ammunition to reject it. The fact that there are about as many little problems with MS Office (plus the big problem that if your data is in a Microsoft format, you really don't own it anymore) will not be mentioned.

    I've never seen a PC with Linux preinstalled in any store. I live in Switzerland, where Walmart does not operate AFAIK. There are dozens of stores which sell computers. They all have Windows preinstalled. It is difficult to avoid paying Microsoft when you buy a computer here.
    When I buy a computer, I go to a store which will sell me the case, motherboard, disk etc separately, I assemble them, then I install Debian from an old set of CDs, then I connect to the internet and do the apt-get update/apt-get upgrade thing. Frankly, it would be more cost-effective to buy a machine with Windows preinstalled, and install Debian on that. For me, avoiding paying the Microsoft tax is a point of principle, for which I'm willing give some of my time. Most people here who want Linux will do the easiest and most cost-effective thing - pay for Windows, then throw it away.
    There are mail-order companies which will sell you a Linux PC, but mail-order is not a big slice of the market here.

  8. Why do you pay attention to ZDNet? on ARM: The Non-Evil Monopolist · · Score: 5, Insightful
    ZDNet finds it strange that no one seems to have anything against this company.

    What ZDNet is implying is this: "People don't like Microsoft because it's a monopoly. But they don't dislike ARM, which is also a monopoly. That's inconsistent and illogical."

    Firstly, it's highly questionable whether ARM can be called a monopoly in the sense that MSFT is, because ARM has only about 80% of its market, vs over 90% in the case of MSFT. ARM's competitors have more than twice as much market share as MSFT's competitors.

    But, much more to the point, ARM has not engaged in illegal practices to bankrupt its competitors. Remember, for example, Microsoft's piracy of Stacker's technology. Remember how they broke Netscape, by reducing the price of their own browser to zero by cross-subsidizing its development. Today, MSFT is trying to strangle Linux by concluding agreements with PC vendors which prohibit sales of dual-boot systems. These agreements, forced on PC vendors by MSFT's enormous market power, are almost certainly illegal, but taking MSFT to court would cost many millions of dollars and the case would last for years. These examples are just the tip of the iceberg.

    MSFT's attitude is, it's OK to break the law if you can get away with it or if the benefit exceeds the costs. That's why Microsoft is widely (and correctly) perceived as evil, not because it has a large market share.

    When I saw this news, my reaction was that it's great and I want to support it. Verisign et al have been too greedy for too long.

    But we have to be careful that we don't let our "wish to believe" blind us to the need for some caution here. Take at look at CACert's site. You'll find carelessness, spelling mistakes, pieces that have not been thought out. Running a CA properly requires meticulous attention to detail, and their site shows the opposite. On the very first page when you sign up, it asks for your name, date of birth, and "country". Is that country of citizenship, or country of residence?

    Then there's the reliance on "government ID". If somebody presents Nigerian ID, or Dominican Republic ID, what exactly is that worth? It's not worth anything, you can bribe officials in those countries (and many others) to issue whatever official document you want. Does that mean that citizens of Nigeria can never be trusted? That's well over 100 million people in just that one country, most of whom are honest and trustworthy. It's ridiculous to exclude so many people from receiving certificates just because their bureaucrats are corrupt, and it's completely contrary to the transnational spirit of the Internet.

    In conclusion, the idea behind CACert is a good one, but the people running it don't seem to be doing a good job. I hope that somebody else takes up the idea and does it better. There is no reason why there should not be more than one volunteer-based CA.

    There are two problems with this. As another message pointed out, not all governments are equally trustworthy. Would you trust an ID issued by Nigeria? Or would you wonder how easy it is to bribe a Nigerian official to issue one in any name you wanted?

    Now look at it from the viewpoint of a Nigerian citizen. How can he/she get acceptable ID? Clearly, not from the government.

    The second problem is that some people are stateless, i.e. no government acknowledges them as its citizens. There are many countries which do not grant automatic citizenship to persons born there (Germany is one). And there are a few governments which give themselves the right to cancel the citizenship of one of their own citizens.

    It's not $34 million. It's vouchers which can be used to buy hardware, Microsoft software, and non-Microsoft software.

    More than half the lifetime capital cost of a typical working PC is the software. And, because Microsoft has a monopoly on operating systems and on the most profitable applications (Microsoft Office), a good chunk of the software expenditure will go straight back to Microsoft. The total cost of this settlement to Microsoft is considerably less than $34 million. It's like a cheap promotion for them. That's why this is a really poor settlement. A fair settlement would have required Microsoft to pay in cash, not vouchers. That's the only fair way to compensate people who were forced to buy bundled software, when they really didn't need to pay for any software at all.

    Who cannot live an excellent lifestyle on the interest alone on a million dollars? No one.

    You can't. The current risk-free short-term interest rate is about 1.1%, which is less than the rate of consumer-price inflation.(Federal Reserve Statistics). There are various measures of consumer price inflation varying from 1.7% to 3.1% but they're all bigger than the risk-free interest rate.
    You can get more interest by taking risks, notably by buying long-term instruments. Part of the risk in a 10-year bond is the possibility that inflation and interest rates will rise in tandem, as they did in the 1970s, reducing both the value of your interest and the value of your capital.
    You can buy inflation-indexed US Treasury bonds. But, first, they cost more than the price at which they were issued (and at which they will be redeemed), and secondly, the money which is supposed to compensate for inflation is taxable - so it won't fully compensate for inflation.
    The bottom line is that nobody can live on the interest on $1,000,000, because after you eliminate risk and allow for inflation, there isn't any interest.

    Or maybe we should just mandate that CEOs can't make more than, say 1000 times what their lowest paid employee makes.
    In the so-called "robber baron" era of raw, unfettered capitalism, the late 19th century, when people like Andrew Carnegie and John Rockefeller amassed huge fortunes, a CEO typically was paid about 40 times as much as the median employee. (It makes more sense to use the median as the benchmark instead of the lowest-paid because it's a more stable number).
    A CEO who pays himself more than 40 times the median salary at his company is basically stealing. I see no problem with a law which says that "compensation" in excess of 40x the median salary is prima facie evidence of theft. Mr Grasso comes to mind.
    Of course, a CEO could rebut the presumption of theft by showing that he had increased company profits commensurately with his salary. But, studies seem to show that a company's change in profitability is not significantly correlated with the CEO's salary.
