was written. So you missed the point of my example.  FWIW: if you want to
pick nits, in this case, the solution with the former is redundant with the
latter.  IMO, That's ok as it follows in the basic tradition.  UNIX has a
number of ways to do similar things/solve the same problem, because it
offers tools, the system designers do not try to dictate a singular
solution.

As I fear by the reaction, many of you have missed the point of what I was
trying to say. I guess I did not do that clearly.  Let me try in a shorter
form.

The basic idea of the original Unix was that was small and simple and in
Dennis' words, 'ran on modest hardware.'    The designers of UNIX also did
not try to solve any one particular problem but offered a set of tools for
a >>programmer<< take upon her/himself to do so.

The issue is that the target >>user<< of UNIX had devolved from that of a
'programmer' but rather the elusive 'end user' and her/his
view/requirements tend to be "solve my problem now -- I don't care how -
just do it I don't want to think about it - make it go away."   So over
time, we hid a lot of the simplicity in features that were built on
features (often warts) that were built on other features (often other
warts).  Mashey had a great visual in his "small is beautiful" talk using a
'build slide' in PPT terms that demonstrated the problem.

I was commenting on the OPs post of the paper picking on UNIX, the UNIX
Shell, and where we are today *vs.* 50+ years ago.  My other point is the
authors need to get over themselves and recognize that* they are not making
a really new argument*.    Folks were not too happy with many of the BSD
'features' either, but now those same features (like head(1) or BSD sockets(3))
are considered SOP for nay new UNIX and you have to have them - even if
there are other if not 'better' ways of doing the same thing.
