Good book overall. Two short comings. The first is that it is a bit dated. But that's due to when it was written. The principles are still good so it's not hard to figure out 'updates' yourself.The one that cost it a star was that a lot of the book looks like a scan or copy of a earlier copy. So it has some issues with fuzzyness of the print.
