Anyone that have been programming for a while will find everything written is common sense.

Not a hacker or security guy,
But playing with C and breaking things was fun.

so got little bored for over explaining some concepts.

I have read the 2nd version,
It's a classical book that you must own,
and keep it as reference.
Many common sense refactoring if you have been programming for a while.
