  1. Re:1000 DVDs? on Suggestions for a DVD Video on Demand System? · · Score: 1

    That makes sense. The VHS tapes in a rental store cost more because they are supposedly higher quality media, which stands to reason. If you watch a tape you recorded yourself on cheapo media, it will wear out after only a few viewings.

    like for temprature, a lot of people would get confused an thing that 40 degrees C is pretty cold when in reality it's not.
    I think that a system based on Kelvin instead of Celsius would be better. Then nobody would imagine any congruency between temperatures in the two scales.

    In the context of the comic they at least make a little bit of sense. However, in the fortune cookie file, they were disconnected and with no context at all. I personally never saw a single Zippy fortune that made any sense.

  4. Re:Still binary.. on Intel Devises Chip Speed Breakthrough · · Score: 1
    If I remember correctly, the optimum base for data size is base e (approx 2.7). I guess that base 3 would be the best we could achieve. Can anybody who knows more about information theory back me up?

    Apparently, there has been some information theoretical research into computing with arbitrary base arithmetic. For instance, On-line multiplication in real and complex base.

    In addition to this, you would need to find a medium capable of carrying a tri-state signal (electrons are not best suited for this). In fact, due to the fact that we have a tough time determining on and off sometimes, I would personally suggest we leave it at binary for the time being.

    Perhaps light would be better suited for non-binary signalling. With electrons, in a normal digital signal, information is encoded in presence or absense of current (or voltage in some circuits). This makes it hard to have a three-state signal, because you have to have at least one more distinguishing signal. It is possible to construct a circuit that uses a high voltage (or current) as a 2, a low voltage (or current) as a 1, and no current as a 0. Alternatively, you could use a signal based on negative, zero, and positive voltages. However the difficulty with such a system comes in state transitions. For instance, in the first system, how do you transition from high voltage to none w/o going through the low voltage state. Optical computing on the other hand, could have several possible frequencies of light for each input and output.
  6. Re:Worms via email on Linux, damn near impossible on The World of Virus Writers · · Score: 1
    The only place where a user should have write access is their own home directory, and anywhere a user has write access, there should not be execute priveledges.


    I am trying to imagine a context where this would even make sense... What are users doing even logging into your system then? What benefit is there of giving them shell accounts? Since the shell is a scripting language, and any script can be entered on standard input and executed, it seems rather arbitrary to me. Of course you can't run binary executable files, but any shell script could still do rm -rf / (which would only affect the files the user has permission to delete obviously).
  7. Re:The router analogy on The 100-Million Mile Network · · Score: 1

    A "friend" of mine one time was trying to flash the bios on his scsi card, and the flash failed. He couldn't boot the computer with the card in, but he needed the card to access his boot drive as a temporary measure, so he booted the computer with the card out, then once the bios had passed the stage where it would try to initialize the scsi card, he jammed it into a pci slot (note, this was most definitely not a hot-swappable part). The first two times he didn't get the timing right, but the third time he got it exactly right. He later had some problems with the motherboard, and called tech support. Come to find out, he had blown some of the picofuses on the mb!

    With Grafitti, nearly all letters were drawn with one stroke (the only exception is X)

    I used a stroke that was the mirror image of the letter k (basically a reverse lowercase alpha) for x. Grafitti was definitely nice for taking notes.

  12. Re:The heart of the Toaster was a custom ASIC on Source of Amiga Video Toaster Software Released · · Score: 1

    Alas, I don't think the Video Toaster did true chroma keying, only luma keying. That was a major wish of mine for a long time when I was in high school, true chroma keying. Without it, the best we could do was have our people wear light outfits and shoot thim in front of a black curtain with very hot lights, and then we could approximate the effect, but you could still see through their shadows. Pretty cool actually, but definitely not something you would want to do for a production quality broadcast.
