roboq6, are you making jokes here ;)
Operating systems are among the most complicated things in the world of
programming. They are not some high-level application, but include relatively
high-level applications as well as very low-level applications as a kernel
and various drivers. The current Linux (I'm talking about the kernel of
GNU/Linux) has somewhere around 70-80MB. This is unformatted text. Try typing
a big amount of text into a simple editor like gedit, save it, look at the
size. Imagine how much text it will take to reach 70 MB. To be fair, a big
part of it are device drivers, but still.
Highly skilled professionals can understand how an operating system works, in
all details. Normal users, power users, newbie programmers like myself,
cannot. I'm not talking about some basic concepts, I talk about full and
complete understanding of all possible layers here, all the way from the
basic environment down to wher BIOS starts.
