Can be skipped. Basically this book doesn’t suit me at all. Initially most of the tips are elaborately described for windows. Being a linux user , i had to skip those pages. Rest of the book talks about many good practices in a very shallow manner . In those pages author narrowed down to some particular languages (I had to skip pages again ) . Basically i expected a more theoretical and abstract approach which is completely missing in this book . Will explore some more books in this genre.
