NUXI problem
     
         /nuk'see pro'bl*m/ The problem of
        transferring data between computers with differing {byte
        order}.  The string "Unix" might look like "NUXI" on a machine
        with a different "byte sex" (e.g. when transferring data from
        a {little-endian} to a {big-endian}, or vice-versa).
     
        See also {middle-endian}, {swab}, and {bytesexual}.
