  1. Re:Ending up down the wrong path on Scientific American on 3-D Chips · · Score: 1

    A grid is like an array, but I'm referring to the lines separating the boxes, not the boxes themselves (which is what arrays are).

  2. Re:Ending up down the wrong path on Scientific American on 3-D Chips · · Score: 1

    Chips are 1D? I don't think so -- how do you make a physical loop in 1D?

    If all that was in the chip was one long line of parts, then yeah that would make sense. It's not tho, the circuit is closer to a grid than a line. My vote's on 2D.

    And whether it's produced by layering of 2D sections, or by some funky 3D fabrication process, I would say as the number of connections between layers approaches the number of connections on a layer (in one direction), it's closer to real 3D circuitry.

    Is "single system image" the same idea as "single-address space"? (as the OSs listed at http://www.cs.arizona.edu/people/bridges/os/sasp.h tml for example)

    If modifying hl is ok:

  5. Re:Geee, welcome to software planned obsolescence on Win95 Lifecycle Draws to a Close · · Score: 1

    Windows isn't just an OS. It's an OS plus a set of standard libraries and applications, mixed up *really* well.

    Since the OS and standard libraries aren't well divided, it's not practical to allow people to simply upgrade the kernel or the libraries, but not both.

    So yeah, you can do all that stuff in DOS, but not as easily because you have to rewrite all the libraries that you could just use with Windows 2000. (screw xp ;)

    And as for bloat, well as far as Microsoft is concerned, hardware is cheaper than software. In reality this isn't true, but the cost is distributed and MS doesn't pay it.

    All the ineffeciency and sloppiness of their coders may have been deliberate from the beginning, or it may have just turned out to be useful later on. Yes, it benefits them by forcing users to upgrade, but as things are now it would be difficult and costly to avoid.

  7. Re:Reasons why paper replacements are still far aw on Electronic Paper · · Score: 1

    epaper = paper replacement?

    Most of the epaper stuff I've seen *are* paper, with two differences:
    1. you can change its content electronically
    2. you probably don't want to write on it with ink

    So let's see...
    "conventional screens are just tiring for the eyes" no problem, this looks just like paper
    "you can just write on printed pape" ah, well... you'd need a special stylus & it wouldn't quite be the same
    "Cost is also an issue" yes, but that's constantly changing
    "People will be much more prone to copy e-books than normal books" that depends -- why would you put an io port on an "ebook"? Make each book out of one sheet of epaper, only allow access to it from that sheet. Only way to copy is with a photocopier. (or with hacking the hardware, but that's much more difficult than software)
    "people just like to hold some physical publication in their hands" check. Physical, if not exactly the same.
    "some documents need to be physical to have legal status" They're working on that, and I'm afraid.

    Personally, I don't want epaper to replace paper, I want it to replace my monitor. A poster sized display that's easy on the eyes? Heck yeah!!

    Heck, Just create your basic client server in c++ or whatever and you'll notice that it is not recognized by the software anyways..... I started to learn sockets and create client/server chats, remote access for work, etc. My anti-virus, anti-trojan software never picked up on it... only my Zone Alarm caught it.

    Network connections are probably not something that antivirus software would look for. Monitoring (or attempting to) all keystrokes in the system might be. I wonder if they complain about programs that install a system-wide hook...

  16. Re:And what about... on Mapping Gravity · · Score: 1

    You can make it have distance units by multiplying it with c (the speed of light).

    Ah, that works.

    One popular choice is called the proper time. So, yes, in a sense you measure movement through time against "another time axis".

    Except that's not actually a different axis, it's the same one stretched differently, with the tick marks in different places. You can specify the ratio of local time to proper time, but that's not the same concept as that of distance to time which is commonly called motion. You could convert the local time to distance, but that's dishonest (unless you also convert proper time to distance) and doesn't work if you want objects at rest to move through time.

    (this is great, the post that didn't understand me was mod'ed up and the one that knew what I meant and actually had something useful to say is stuck down here at 1)

  17. Re:And what about... on Mapping Gravity · · Score: 1
    actually, "moving through time" at all is pretty meaningless, unless you have another time axis to measure against

    Why? If I'm moving at all (though the effects only become noticable relativisticly), I'm 'moving through time' at a different rate than someone in an different inertial frame. You don't need a y and z axis to describe differences in motion along x. I get headaches thinking about 4 dimensional geometry.

    You need the axis you're moving across and a time axis for motion. It's a little difficult to see because we're so used to having a time axis, we don't usually see it. A stationary observer's time might work as a reference, unless you want them to be moving through time as well. (Think about it: At what rate are we moving though time, including units? Remember, units along the same axis cancel.)

    You can go slower than light (everything we see) or you can go faster (tachyons?).

    IIRC, tachyons (if they exist) do their thing by having an imaginary rest mass, so their mass squared is negative. So anything with a real rest mass cannot go faster than light.

  18. Re:And what about... on Mapping Gravity · · Score: 1

    3 things:

    The effect of velocity on perception of elapsed time is not linear as far as i know. (I could be wrong)

    Time is not measured with distance units, so moving through time "at the speed of light" is meaningless. (actually, "moving through time" at all is pretty meaningless, unless you have another time axis to measure against)

    What does this have to do with the lumpiness of the earth or variations in gravity along its surface? Force (say, gravity) does not require motion.
