About the Authors

Susan Douglas is the CEO of Conjectrix, Inc., a software consulting firm specializing in

database- and security-related issues. When she’s not busy at the computer, Susan is

probably throwing pottery, glassblowing, or horseback riding.

Korry Douglas is the Director of Research and Development for Appx Software. When

he’s not working on computers, he’s making elegant sawdust in the woodshop.

Together, they are the coauthors of Red Hat Linux Fedora Desktop For Dummies and

PostgreSQL .

Susan and Korry enjoy life on a farm in rural Virginia where they raise horses and small

livestock. They both telecommute, so they have more time to spend with their 200 or so

animal friends. If they’re not at home, they’re out riding roller coasters.

Authors’ Acknowledgments

We would like to thank all the staff at Wiley who have supported this project, from start

to finish. Without the help and direction of Terri Varveris, organizing this book would

have been an impossible task. Becky Huehls’s editorial help and guidance have kept this

project rolling along on schedule (fairly painlessly, we might add). We also want to

extend a big thanks to the technical editors who’ve kept us honest throughout the

course of the book.

Thanks go also to all the supporting staff at Wiley that we’ve never met. We know you’re

out there, and we appreciate your efforts and support.

Thank you also to all the programmers and developers that make open-source software

such an interesting, productive, and fun environment to work in.
