Those who don't understand UNIX are doomed to reinvent it, badly:
I've been playing with
MacOS X a little recently
(in between doing a dozen other things), and all in all, it seems
pretty doovy. One thing I'm not too fond of is that the UNIXyness
only goes up so far. For example, there is no audio device under
/dev. Presumably, to access audio from a program, you have to make
all sorts of arcane API calls, with their own names, structures, data types
and so forth; a less than ideal state of affairs when there are
open(),
write()/read() and
ioctl().
