Re: Your new book

I guess that your review is fair (and balanced, of course). In my review, I confessed the sin of having a math degree, so the perspective is necessarily, different.

To give credit where it's due, I have to say that the part about .trc file details and the perl scripts dealing with it are worth buying the book.
