27. Chapter 27 Afterword

1. Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Java Cookbook is a domestic chicken. Domestic chickens (Gallus gallus) are descended from the wild red jungle fowl of India. Domesticated over 8,000 years ago in the area that is now Vietnam and Thailand, chickens are raised for meat and eggs, and the males for sport as well (though cockfighting is currently against the law in many places).

With their big, heavy bodies and small wings, these birds are well suited to living on the ground, and they can fly at most only short distances. Their four-toed feet are designed for scratching in the dirt, where they find the elements of their usual diet: worms, bugs, seeds, and various plant matter.

A male chicken is called a rooster or cock, and a female is known as a hen. The incubation period for a chicken egg is about three weeks; newly hatched chickens are precocial, meaning they have downy feathers and can walk around on their own right after emerging from the egg. They're also not dependent on their mothers for food; not only can they procure their own, but they also can live for up to a week post-hatch on egg yolk that remains in their abdomen after birth.

The topic of chickens comes up frequently in ancient writings. Chinese documents date their introduction to China to 1400 B.C., Babylonian carvings mention them in 600 B.C., and Aristophanes wrote about them in 400 B.C. The rooster has long symbolized courage: the Romans thought chickens were sacred to Mars, god of war, and the first French Republic chose the rooster as its emblem. Emily Quill was the production editor and copyeditor for Java Cookbook. Claire Cloutier, Colleen Gorman, and Jane Ellin conducted quality control reviews, and Edith Shapiro, Sada Preisch, Lucy Muellner, Linley Dolby, and Matt Hutchinson provided production assistance. Ellen Troutman-Zaig wrote the index.

Hanna Dyer designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from the Dover Pictoral Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

Melanie Wang and David Futato designed the interior layout, based on a series design by Nancy Priest. Mike Sierra implemented the design in FrameMaker 5.5.6. The heading font is Bitstream Bodoni, the text font is ITC New Baskerville, and the code font is Constant Willison. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. This colophon was written by Leanne Soylemez.
