AIDX

AIDX n. /aydkz/ n.  Derogatory term for IBM's perverted
   version of UNIX, AIX, especially for the AIX 3.? used in the IBM
   RS/6000 series (some hackers think it is funnier just to pronounce
   "AIX" as "aches").  A victim of the dreaded "hybridism"
   disease, this attempt to combine the two main currents of the UNIX
   stream ({BSD} and {USG UNIX}) became a {monstrosity} to
   haunt system administrators' dreams.  For example, if new accounts
   are created while many users are logged on, the load average jumps
   quickly over 20 due to silly implementation of the user databases.
   For a quite similar disease, compare {HP-SUX}.  Also, compare
   {Macintrash} {Nominal Semidestructor}, {Open DeathTrap},
   {ScumOS}, {sun-stools}.
