  1. Re:Mythbusters on Archimedes Death Ray · · Score: 1

    A coating of mercury on a copper or copper alloy surface would provide good reflectivity. Copper is easily worked; mercury would fill scratches and eliminate the need for a high polish.

  2. Easy to aim on Archimedes Death Ray · · Score: 4, Informative

    There is a technique for aiming the mirrors easily and quickly, provided that one person holds each mirror and the mirrors are reflective on both sides. Make a hole in the center of the mirror. Open only one eye. Position the mirror so that you see the target in the hole and the sun shines through the hole onto your face. Tilt the mirror so that the image of the spot of sun on your face is centered on the hole.

    Making replacement cartidges or refill ink as good as OEM isn't easy, and AFAIK nobody is doing it.

    Here's your chance to become rich. If it's so easy, YOU do it.

  4. Re:Well it clearly matters to some people... on Good bye Dark Matter, Hello General Relativity · · Score: 2, Insightful
    It seems to me that the "theoretical framework to explain the data" was already there; people were just too lazy or didn't think to apply the known framework. "Newtonian gravity is good enough; we don't have to use the more complicated Einsteinian gravity" is the essence of this viewpoint.

    I've seen this sort of thing happen occasionally in widely used reference books and been guilty of it myself. With computer modeling so much more widely available and easy to use these days, there's less excuse for not being thorough.

    Private ownership of an airport does not mean that it would be owned by an airline. Even if an airport were owned by an airline, that does not mean it would serve only that airline. (It would not be in its best interest to do so.)

    Practice has shown that government ownership and operation of airports is inferior to private ownership.

  7. Re:Who wants a new video format anyway? on Why Microsoft Hates Blu-ray · · Score: 1

    In 1980, when the VHS vs Betamax war was active, VCRs cost US$800. Today, DVD players cost US$30 and the dallar is worth half what it was in 1980. Few people are going to be upset if they have to buy a player or 2 every few years.

    When doing stuff like this, I've had success with taking 8 bits at a time to index a table which returns the number of bits set to 1. Repeat until the limit is equalled or exceeded; work backwards to get the exact position. Bigger but faster.

  9. Re:article text on When to Leave That First Tech Job · · Score: 1

    The choices are offices, cubicles, and bullpens. I've spent more time in bullpens than the other two combined. Other things being equal, cubicles are a step up. Don't assume that your shiny new college degree entitles you to an office.

    Prager's claims are fairly well delimited and seem to be accurate. He also acknowledges that there is hysteria on the right and gives examples. I oppose a lot of what he stands for, but your claims are unjustified.

    "more fuel efficient (and thus cheaper and cleaner)"

    Cheaper and cleaner does not automatically follow from more fuel efficient. The tricks required to increase efficiency cost money. The technology that cleans often lowers efficiency.

    Judging by the tone of your comment, it's the "free" in "free trade agreements" that you object to.

    US workers have two advantages. We're working with expensive devices that previous workers' efforts have paid for (we're richer), and your claims to the contrary notwithstanding, we do work harder -- more hours per week, more weeks per year.

    You have to start somewhere. That "somewhere" is a set of axioms. A well-chosen set of axioms makes possible a mathematical system with real-world utility.

    I want a multimonitor setup, but I have a caution here. I currently have a TV running most of the day to the right of the computer monitor. I find that if I shift the direction of my eyes instead of turning my head to watch the TV, my right eye feels sore by the end of the day. Pay close attention to how you feel.

    Look at Intel's profit margin, it's below 25%. http://finance.yahoo.com/q/ks?s=intc/. There are lots of expenses in running a company. Only the fastest P4s are in the $600+ region, many are below $100 retail. http://www.pricewatch.com/. The cheap ones cost every bit as much to make as the expensive ones; it's just a matter of supply and demand.
