    You can. The problem is that if you don't get an exact match between the mechanical properties (hardness, ductility, etc) of the tooth and the filling, one or the other will get damaged over time.

  2. Re:How do they come up with the numbers on The Air Car Nears Completion · · Score: 1

    Of course the compressed air tank has got to be a serious danger and likely capable of rupturing during an accident, possibly more so than gasoline tank. One must wonder if that tank is designed from paper and carbon fiber as well to achieve a low enough weight to keep from wrecking the mileage.


    Using a carbon-fiber composite tank instead of a steel tank does two things. As you noted, it improves the mileage. But it's also safer: a carbon-fiber tank, when punctured, vents rapidly through the hole, but the cross-bedding of the fibers prevents the hole from getting larger (ie. exploding).

    but so do things like the type (actually, speed) of music you're listening to


    I can certainly agree with this: on a recent cross-country trip, I had four CDs in my car's changer: two CDs of Mozart works, a CD of calming New Age music, and a CD of Sousa marches. My average speed with the Sousa CD playing was 30 MPH faster than with the New Age CD playing.

    Then again, perception of speed is also affected by recent experience: think how slow it feels when you come off a high speed road into a town, even if you're doing the limit around town, and compare that with how that limit feels when you're just starting driving and already in town.


    Going from a backcountry dirt road to a two-lane highway is worse: on the dirt road, you drive in the center of the road, at a speed dictated by the condition of the road, and your main concerns are road damage and oncoming traffic. On a two-lane highway, you drive on one side of the road, at a speed dictated by a sign on the side of the road, and your main concerns are maintaining speed and following your lane. I'll often find myself either driving at a speed appropriate for road conditions (90+ MPH) or driving at dirt-road speeds (15-25 MPH).

    It probably wouldn't help. It takes a few years for a treatment to go from "we found it" to being a medicine or procedure. If you're given five years, and there isn't already a candidate treatment in the works, you're probably out of luck.

    No, a laptop has a screen big enough to properly review the photos. I typically throw away about half the pictures (out of focus, blurred, overexposed, subject moved out of the frame, or simply redundant with other pictures) and select about 5% of the remainder for a slideshow.

    A one-year trip might generate 1000 pictures to illustrate Wikipedia articles, 1500 pictures to use in slideshows (a slideshow of the whole trip might include one shot of Vienna, while a slideshow of my adventures in Austria might include 25), and 1000 subject-free pictures to use as backgrounds for art projects, out of 50,000 shots total.

  12. Re:throwing up my hands on Is Vista a Trap? · · Score: 1

    Dude, neither of these is a flaw with Vista. Having a crappy video card and 512 MB of RAM is a flaw with your computer, not with the OS, and even a minimal amount of research would have informed you that a computer with such modest hardware would not have a good experience with VISTA. Did you bother to read anything about it before you upgraded?


    Twelve months ago, when the corporate higher-ups decided that we needed to test our software on the Vista release candidates to make sure that it would work, I was given the job of doing so. I determined that this was the machine best-suited to running Vista, and only one of two computers in the office capable of doing so. It's a fairly typical office computer, and more powerful than about 70% of the computers our software is currently running on.

    I see a lot of UAC complaints on Slashdot but very little on details as to what the person is doing to garnish so many prompts. So here's my proposal to Slashdotters: If you've seen more than 5 UAC prompts in one day, what were you doing to cause them?


    Most recently? Debugging the uninstaller for the software I'm developing. I get:
    1 UAC prompt when I run the remote debugger -- it needs to listen for network connections on port 6969
    2 UAC prompts when I run the installer
    2 UAC prompts when I run the uninstaller
    At this point, the debugger attaches to the uninstaller.
    1 UAC prompt when I move the files the uninstaller missed from the Program Files directory to the recycle bin
    1 UAC prompt when I empty the recycle bin

    And because the debugger crashes after each run, I get all seven prompts every single time.

    #2. Apples and Oranges (IIS on Windows versus Apache on Linux? Which are we comparing?)
    #3. Lack of detail: You can't see what system calls are really involved. No indication of configuration. No version numbers.

    So that puts it in the realm of FUD, although the blogger does explain that its just a blog.
    You can still get useful information out of it. For example, you can see that the IIS graph shows ten entry points, one of which calls a dispatcher function that leads into a godawful mess of spaghetti code (the bulk of the graph). The Apache example, on the other hand, has a single entry point leading into a set of about four dispatcher functions, with the program flow reasonably well-modularized. If you were to combine each chain of function calls in the Apache example into a single node, it would be a very clean graph.

    With all the eye-candy turned off, Vista will run on 512 MB, but a bit sluggishly. With everything turned on, it runs just fine on 1GB -- though I'd recommend 2GB if you're doing serious gaming.
