http://www.linuxjournal.com/article.php?sid=7035&mode=thread&order=… some quotes: << LJ: Is it true that you suggested the name "UNIX" for the long ago OS, Multics? What does that word mean? BK: Yes, long ago. Multics was an acronym for something like Multiplexed Information and Computing Service, and it was big and complicated because it had many of everything. I suggested Unics for Ken's new system, because it was small and had at most one of anything. (Multi and uni are both Latin roots, so it was a very weak pun.) Someone else spelled it with the letter X; no one can remember who. >> << LJ: What UNIX OSes do you like? Linux? BSD? BK: The way I use them, which is as a casual programmer, it doesn't matter--they are all the same. If I encounter some difference, it only makes me mad, because there really isn't any reason for things to be different most of the time. I use Solaris at Princeton, Irix when I visit Bell Labs, and FreeBSD on my Mac; I also have Cygwin on several PCs so that standard tools are readily available. >> But Brian, FreeBSD does not run on a Mac unless you don't need features like booting up all the way. http://www.freebsd.org/platforms/ppc.html << 3 July, 2002 : This page has been significantly updated. FreeBSD/PowerPC currently boots almost to the point of reaching single-user mode. >> Oh well.
