getting old I suppose.
The worst part of the proper UNIXs disappearing is the kids today seem to think Linux is POSIX (not that they really even know what that means seeing as you drop them into /bin/ksh and they panic). POSIX to them is whatever the latest RHEL/Fedora dictates (money talks and companies are often penny wise and pound foolish). When really Linux has largely become Windows lite designed for laptops primarily. Who cares about stability when you can just throw more commodity hardware at the problem?
