Bought it yesterday when reading this and read it halfway now; I like it. And thanks for taking the effort writing it!

As for remarks;

I second the reliance on the additional libraries; I think most readers are in fact, as you say in the book, purist... And won't like his reliance. No matter if it makes things better or not.

To that point; I personally like your opinionatedness in the book; on HN (etc) you would be shot down for many remarks you make in the book, but I like them here from people and do like that about the writing.

I wouldn't put smileys :) in a book like this, but that's a matter of taste.

And maybe a proofread by a native English speaker could have been good, but nothing was bad per se, it's just, having worked for 5 years in Ukraine (Lviv/Kyiv), that I recognize the way sentences are constructed and that is sometimes not the most readable in English. But I am not native English, and, again, for this kind of book, it's definitely fine, it would just be a bit of icing on the cake.

Thanks for the feedback! I recognize the deficiencies of my English writing. Moreover, the current state of the book is, in fact, much-much better than the original manuscript thanks to the efforts of Dr. Robert Strandh, phoe, and Apress proofreaders. As for the residual ugliness - c'est la vie...

It's great work anyway! The main point is the technical content; kudos for that! And of course persisting to write it to the very end instead of quitting like most of us do.
