The Jargon File (version 4.4.7, 29 Dec 2003):

HP-SUX
 /H?P suhks/, n.

    Unflattering hackerism for HP-UX, Hewlett-Packard's Unix port, which
    features some truly unique bogosities in the filesystem internals and
    elsewhere (these occasionally create portability problems). HP-UX is often
    referred to as ?hockey-pux? inside HP, and one respondent claims that the
    proper pronunciation is /H?P ukkkhhhh/ as though one were about to spit.
    Another such alternate spelling and pronunciation is ?H-PUX? /H-puhks/.
    Hackers at HP/Apollo (the former Apollo Computers which was swallowed by HP
    in 1989) have been heard to complain that Mr. Packard should have pushed to
    have his name first, if for no other reason than the greater eloquence of
    the resulting acronym. See sun-stools, Slowlaris.
