This question of mine merged with this one while the questions were pretty different with each other. And this answer of Gennaro Tedesco (before is edited by me, even after that!) is completely meaningless.
Why must those questions be merged?
I could explain clearly why those questions were merged if the moderator who merged the questions, wasn't deleting comments related to that answer of Gennaro Tedesco. But now, I cannot.
If you have access to deleted comments and you can recover them, please help for clarification of this matter.
