  1. Validation vs. verification on Are You Using Z-Notation to Validate Your Software? · · Score: 3, Insightful

    Great I just passed an exam in this, but lets see if I still remember it..

    First you we have to get the question right - are you talking about validation or verification of software? They are quite different from each other:

    • Validation: Are we building the right product?
    • Verification: Are we building the product right?

    The above is a quote of Boehm from 1979 I think... can't remember the exact title.

    As you can propably guess there is quite a difference betweem the two. Unit testing is a method for verification, but from your description Z sounds like validation to me.

  2. Re:Instead of PCI on Want a Sparc Workstation for $995? · · Score: 1

    The Sun site dosn't mention the SUNPci card as being part of the blade 100 workstatioin. You will have to pay extra $$ to get it.
    The SunPCI is a nice idead, but 64MB of RAM simply isn't enough for most M$ apps.

  3. Re:very confused... on XFree86 4.0.2 Released · · Score: 1

    XVideo is an extension to X to allow mpeg/video accelerations, and tv tuner support, and a few other things.
    Does this mean that the picture from TV tuners will improve? A friend and me have exactly the same TV tuners (Hauppage Cinema, BTTV driver). Under NT his picture quality is worse than the one I get under Linux/X3, but when he upgraded to Windows 2000 it improved a lot, and now the worst quality is on my Linux box. Would an upgrade to X4 improve this?
