in reply to Perls of Wisdom
I bought the book recently and read it over a few days, and
enjoyed it. Some things (especially in the Webmaster's Toolkit section) I skimmed rather quickly but I observed bits of code and/or techniques that I mentally noted with the idea that I might look them up in the future when I was doing something related. Even in a fairly simple article like "Finding Old Things" I found several things that were illuminating. For example, if I had attempted something similar myelf, I might not have thought about the problem of symlinks pointing to directories above the current one (until my code broke and I was forced to.)
Generally, I enjoy reading well written code, and for me the read was quite pleasurable. I am glad to have the book.
It may not be one that I frequently refer to, but it provided me with the chance to read a bunch of interesting articles that I wouldn't have otherwise.
