awesome! "Unfortunately, the book may also appeal to crackers. I truly regret this and wish there were a way to present this material to limit its worth to crackers." this is almost the most elequent thanks i've read so far: "It seems every author always acknowledges his or her family. It has almost become a clichˇ, but that doesn't make it any less true. This book would not have been possible without the support and patience of my family, who have endured more that I should have ever asked them to endure. Thank you. " network emulators!
