To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Despite OTW's reputation, this book is for beginners. He touches on each topic VERY lightly ( something you could learn from the blogs). I expected more unorthodox pentest techniques but's it's your typical run-of-the-mill beginner-level hacking book. I suggest you look elsewhere. Some of the commands don't even work.... totally disappointed. I was hoping for a tutorial-based transformation of a compromised system to a Command and Control system.
