For the second time in four months, I went to Boston and come away with a 900-page book. The second visit was a W3C XSL FO subgroup meeting, and the second book was Advanced Programming in the UNIX® Environment (2nd Ed.) (ISBN 0-201-43307-9).
The book is exceptional, and it has already been useful on one of my client projects. The only possible downside is that delving into this 900-page book further delays my completion of the other 900-page book.
