Acknowledgments

To my wife, Shawnde, thanks for the continuous feedback and frontline editing, and for cheerfully discussing Yahoo! during breakfast, lunch, dinner, and every spare moment in between.

Many thanks go to Brian Sawyer for providing direction and encouragement, and for fine-tuning the text.

Thanks to tech editor Steve Champeon for testing code, double-checking facts, and adding important points to the technical details.

Thanks to Morbus Iff for taking my Perl to task and simplifying the confusing bits.

Finally, thanks to everyone at Yahoo! who contributed tips and hack ideas, including Vijay Anisetti, Stig Sæther Bakken, Dave Brown, Aurora Casanova, David Dueblin, Jennifer Dulski, Marcus Foster, David Hall, Jason B. Silverstein, Jeremy Zawodny, and many anonymous Yahoos. Thanks also to Chris Kalaboukis and Bernard Mangold at Yahoo! Research for lending a hand.
