I don´t complain about ns. Please don´t misunderstand me there.

I only wanted to say that ns itself and it´s acceptance by the users as 
well as its benefit suffer from this situation. But this is not a 
problem due to ns.

That is more than what I said. However, I´m not willing to accept, that 
a CS student can graduate without a sound programing expertise.
That´s exactly the same as if a surgeon could graduate without knowing
to hold a knife.

 From my education and from my professional experience, I say that 
excellent programing skills are compulsory for any computer scientist. 
They are a "must". For a computer scientist a computer is what a knife 
is for a surgeon.

In some commercial programs, the codebase is even older *sigh* ;-)
(Unfortunately, I have no knowledge about COBOL, RPG and PL/1 and I 
don´t like FORTRAN IV very much :-))

Which is basically a good strategy.

And it works the same way for programing. I once told a student, he 
should _READ_ programs. It was always helpful for me to _read_ programs. 
Not that stupid samples from textbooks. But reading large programs. And 
I even learned countless things and techniques from reading the ns2 source.
