  1. Issue not mandatory course but language change on Microsoft Invests in the University of Waterloo · · Score: 1
    It is a good thing that UW is offering a course to people applying to Electrical or Computer Engineering. Programming is an important part of those disciplines but cannot be a required course from high school.

    The problem is if the choice of C# over C++ hurts the quality of the education.

    Note also that over the past decade we have changed from Fortran to C to C++

    Whenever you have media that covers a certain market, mainly provides information on upcoming products and hence gets most of its advertising from the same industry this could happen.

    In addition to video games you can see it in other entertainment. Also in car magazines or electronics.

    You should always make a judgement of the credibility of any information you receive.

    The amount of CD's they have sold proves nothing. The only way to determine whether or not napster had an adverse efect would be to have an alternate universe in which Napster did not exist, measure CD sales there, and then compare it to our world.

    While the law does not provide any "confidentiality" between a reporter and a witness

    Doesn't the law allow a journalist to protect his source?

    I remember watching on Law & Order an issue like this arose where a biker who wrote stories on a BBS claimed to be a journalist to avoid having to testify in a murder case. While L&O is not a consummate source of legal information I would think it reasonably accurate.

  17. Re:Insurance, Fuel and The Sky Car. on Latest Toy: One-Man Helicopter · · Score: 1
    Safety is a big concern. From what I know of the SkyCar it was made with redundant systems (all but one engine could fail and it could still fly) and control systems that truly fly the plane (so you would just be steering in 3-dimensions essentially). These attempts at a fail-safe air-vehicle might address some of the legal concerns.

    Also, aside from the prohibitive cost of purchase it takes a great deal of fuel to fly which means high ongoing costs as well; especially with today's gasoline prices.

  18. Re:Can anyone paraphrase how it works? on First 7-qubit Quantum Computer Developed · · Score: 4
    Okay, I found this explanation (link at the end): Quantum Computers

    The memory of a classical computer is a string of 0s and 1s, and a classical computer can do calculations on only one set of numbers at once. The memory of a quantum computer is a quantum state which can be in a superposition of many different numbers at once. A classical computer is made up of bits, and a quantum computer is made up of quantum bits, or qubits. A quantum computer can do an arbitrary reversible classical computation on all the numbers simultaneously, and also has some ability to produce interference, constructive or destructive, between various different numbers. By doing a computation on many different numbers at once, then interfering the results to get a single answer, a quantum computer has the potential to be much more powerful than a classical computer of the same size.

    The most famous example of the extra power of a quantum computer is Peter Shor's algorithm for factoring large numbers. Factoring is an important problem in cryptography; for instance, the security of RSA public key cryptography depends on factoring being a hard problem. Despite much research, no efficient classical factoring algorithm is known.

    Shor actually solved a related problem, the discrete log. Suppose we take a number x to the power r and reduce the answer modulo n (i.e., find the remainder r after dividing xr by n). This is straightforward to calculate. It is much more difficult to find the inverse - given x, n, and y, find r such that xr = y (mod n). For factoring, all we need to do is consider y=1 and find the smallest positive r such that xr = 1 (mod n). Shor's quantum algorithm to do this calculates xr for all r at once. Since xl+r = xl (mod n), this is a periodic function with period r. Then when we take the Fourier transform, we will get something that is peaked at multiples of 1/r. Luckily, there is an efficient quantum algorithm for the Fourier transform, so we can then find r.

    There are many proposals for how to build a quantum computer, with more being made all the time. The 0 and 1 of a qubit might be the ground and excited states of an atom in a linear ion trap; they might be polarizations of photons that interact in an optical cavity; they might even be the excess of one nuclear spin state over another in a liquid sample in an NMR machine. As long as there is a way to put the system in a quantum superposition and there is a way to interact multiple qubits, a system can potentially be used as a quantum computer. In order for a system to be a good choice, it is also important that we can do many operations before losing quantum coherence. It may not ultimately be possible to make a quantum computer that can do a useful calculation before decohering, but if we can get the error rate low enough, we can use a quantum error-correcting code to protect the data even when the individual qubits in the computer decohere.

    I can see the latter way reducing the cost to consumers as the unit would be less complicated. An advantage of the former is that it works with exising cable network.

    And just how happy do you think advertisers will be about this idea?

    This will just motivate advertisers to find different ways of advertising.

    More effective and perhaps insidious advertising is that which is a part of content; either you want to watch the ad because it is entertaining or the brand is promoted as a part of the show you are watching. In both cases you have absorbed the content and was unable to avoid the commercial promotion. This is the future of advertising.

  22. Re:Should usage precede trademarks though? on Is "coke.ch" A Violation of Coca-Cola's (tm)? · · Score: 1
    I think considering usage and trademarks is interesting. A company should certainly not be able to co-opt a dictionary word for a trademark.

    What about trademarks that are adopted into language. Say in many places
    kleenex refers to facial tissue
    band-aid denotes adhesive bandage

    Obviously it doesn't work the other way either;
    Either trademarks and words must be exclusive (i.e. all trademarks cannot be existing words) or they must refer to different subjects (i.e. Coca-Cola can only prevent someone from using "coke" to refer to a carbonated beverage)

    Generating opposing magnetic fields each having a plane of maximum force running perpendicular to a longitudinal axis of the respective magnetic field;
    The Lorentz force is given by Il x B, which means that the magnetic force is due to a current, and in general, circulates about the current flow.

    This is true, however there is another consequence of the equation you cite. If there is a current and an independent magnetic field perpendicular the medium of the current will experience a force mutually perpendicular to the first two. (id est: current along x-axis, magnetic field y and then force z) generating heat from a heat source along an axis parallel to the longitudinal axis of the magnetic field;

    Unless the heat source is a thin wire, it is difficult to imagine an axial heat source. Heat conduction tends to be uniform, and while I'm not a material scientist, it is difficult for me to think of a material that has non-isotropic heat conduction (ie different depending on direction -- a composite material with fibers might do the trick).

    An axial heat source need only be a material with uniform generation in a cylindrical shape. (any heat generating rod will be the hottest at its centre and heat will travel outwards.
    In the "preferred embodiment of the patent a halogen lamp is suggested as the heat source.
    In any pure isotropic material heat conduction hsould definitely be uniform. The other component of conduction is the gradient. (net heat transfer is from a hotter area to a cooler area) So the shape of the heat generation could affect it.

    It makes perfect sense that a company who holds a trademark has a right to the domain of that trademark. However much I might dislike Microsoft; they do have a rigfht to their name.

    Where there might be more argument is whether or not a company should have a trademark on common names (like the Apple trademark causing that orchard guy above all those problems). I mean I don't think computer.com should be allowed to be trademarked or anything like that.
