   From my view what UCB, Joltz, BSDI and others have done has neither
   advanced the art nor been in the UNIX industries best interest. With
   forethought and malace they incrementally attempted to place the UNIX
   operating system product into the public domain by re-writting it
   line by line while leaving the framework and the fabric of the system
   unchanged ... same global design, major algorithms, data structures,
   internal interfaces, etc ... to what end? Only to attempt to destroy
   AT&T/USL UNIX as a commercial product. At best the debate has
   cost more than a million wasted man-hours that could have been more
   productively used to advance the art with a new design. Their actions
   have been WRONG, WRONG, WRONG!

Wait a moment! Who copied design, algorithms, data structures,... from
whom? UCB from ATT/USL? Or ATT/USL from ATT? I would think the latter
was the case rather than the fromer!!! Unix as we know it today is a
UCB product (mostly, ie the parts that make UNIX usable!), not an ATT
one.  I bet you would not want to work on a PDP-11/V-32 unix - nor
would I (except for historical/amusement reasons). Many of the things
we so much like where written outside ATT and then filtered back in to
ATT unix or were rewritten by ATT.

SO what we like about UNIX (just some features - some of them 
are pretty outdated and we don't like them any more (eg vi), but 
they were at the time a MAJOR step!):

 * written in C				ATT
 * Paging				BSD
 * Fast File System 			BSD
 * Job control				BSD
 * csh (just a personal plug ;)		BSD 
 * IPC/networking/sockets		BSD 
 * vi (eek - but better than ed)	BSD
 * curses 				?BSD?
 * lex,yacc				ATT
 * sendmail 				BSD
 * dbx 					?BSD?
 * termcap 				BSD

AT&T Unix was a good thing, but for its time - much of the
improvement, ie. that which made it into a `product' did not come from
AT&T (Unix got wuite a bit bigger and less elegant in the process - I
doubt that the inventors would want to be associated with the
cancerous beast that UNIX is today - for that reason the started out
anew with Plan9 if I understand things) - and the point where the
input of AT&T code stopped is easily discernable with the last source
license UCB took for UNIX - which is way back when, if I understand
things correctly...

So the people who are writting PD unixes - oops, UNIX is TM - who are
writting POSIX conformant operating systems are ripping USL off? Isn't
it more the case that USL is ripping the CS community off by selling a
system of which they very lttle wrote/invented?
