Do you realize you have been consuming a large fraction of the 
"bandwidth" of this mailing list for your own e-learning of the C 
language and of Linux OS, and for expressing your pathos about the 
reactions of others?

     This list has a lot of short-lived off-topic (or sideways) threads, 
which I consider interesting, your's is really long-lived and that may 
explain the reactions of others. As someone already told you, you might 
better find another list for e-learning the C language.
