  1. Re: 'Z' ^ 'J' ^ 18 ? on Slashback: Petdom, Denial, Confusion · · Score: 1

    ^ stands for xor (bitwise exclusive or). What do they teach in CS classes these days?

    'Z' == 0x01011010 == 90
    'J' == 0x01001010 == 74
    0x00010010 == 18
    result == 0x00000010 == 2

  2. Re:LISP on Windows on Ask Kent M. Pitman About Lisp, Scheme And More · · Score: 1

    You can run GNU emacs (or xemacs, if so inclined) on Windows. Pre-compiled binaries can be found here. Therefore, there ARE free LISP interpreters available for Windows, and all other platforms which emacs has been ported to.

  3. What about cost? on New Batteries Promise 2.5 Times Longer Uptime · · Score: 1
