    “If you’re a UNIX user, all UNIX are pretty much the same. If you’re a UNIX programmer, all UNIX are a little bit different. If you’re a UNIX system admin, all UNIX are completely different! That’s comming from ULTRIX, AIX, HP-UX, Solaris, and Digital UNIX experiences. Might as well count linux, too.” —Bob Koehler, Hubble Space Telescope Payload Flight Software Team
