Subject: Unix evolution
I was giving some thought to the general evolution (I use the term
loosely, here) of Unix since its inception at Bell Labs, and I think it
could be described as follows.
In the early PDP-11 days, Unix programs had the following design
Rule 1. It didn’t have to be good, or even correct,
Rule 2. It had to be small.
Thus the toolkit approach, and so forth.
Of course, over time, computer hardware has become progressively
more powerful: processors speed up, address spaces move from 16 to
32 bits, memory gets cheaper, and so forth.
So Rule 2 has been relaxed.
