I got the book but has been quite busy lately and probably gone through just a dozen of pages, so Im not qualified to give any comment on technical issues. One non-technical thing that I find quite interesting is the presentation. Its the traditional method on writing layout, identation for the first line of each paragraph (in Lucas's book, no identation in first paragraph) and no blank line between paragraphs. I havent seen this kind of method both in paper and online writing for many years.
Thank you and welcome to Daemonforums, M.Lucas
