When i search youtube or things I got alot alot of tutorial, which is kind of confusing. and i fell into whats called Tutorial hell with more content less practical things .
So I think reading by book is best way of learning hacking.
But 
what book should i learn?
I’m already a programmer, not professional but i’m finishing my college graduation and i know all programming language . I feel i’m intermediate level programmer.
Which book should i learn?
My top favourite programming langauge is Python,elisp,common lisp,golang,c++,c,nodejs,html,css.
Please guide me.
I’m dying into this hole @Aina
