Software Engineer & Architect & Evangelist & Pundit & Skeptic
Started with Unix in 1984 in early grade school. I have no recollection of what version but was labeled IBM, maybe a Unix-style shell on mainframe?, then to C64 (all BASIC line editing by LIST and using the up key), Apple ][ (made me the CS person I am today), Windows, Linux and AIX in 1993, OS/400 (sorry, IBM i) in 1997. I'm on OS X now as a client only to my Linux boxen in the "cloud."
Under my own revolution a little now in that I'm starting to be OK with Windows as the server. With a decent shell and vi, it works for me (gasp).
