Red Hat Fedora 4 Unleashed

Red Hat Fedora 4 UnleashedAbout the Authors Andrew Hudson is a regular contributor to Linux Format magazine, the UK's largest Linux magazine. His particular area of expertise is Red Hat–based distributions, including Red Hat Enterprise Linux and the Fedora Project, having worked with the original Red Hat Linux since version 5. Seemingly obsessed with performance, he spends many an evening trying to squeeze more performance out of legacy hardware. Andrew lives in Wiltshire, England, with his wife Bernice who is currently expecting their first child. Andrew does not like Emacs. Andrew can be contacted at andy.hudson@gmail.com. Paul Hudson is a recognized expert in open-source technologies. He is a professional developer and full-time journalist for Future Publishing. His articles have appeared in Mac Format, PC Answers, PC Format, PC Plus, and Linux Format. Paul is passionate about Free Software in all its forms and uses a mix of Linux and BSD to power his desktops and servers. Paul likes Emacs. Paul can be contacted through http://hudzilla.org. Bill Ball is the best-selling author of nearly 20 books about Linux, including several editions of Red Hat Linux Unleashed, Que Publishing's Using Linux, and Sams Publishing's SuSE Linux Unleashed. He is a technical writer, editor, and magazine journalist and has been using computers for nearly 30 years. He first edited books for Que in 1986 and wrote one of the first best-selling Linux books, Teach Yourself Linux in 24 Hours, in 1997. He has authored articles and reviews in Linux Journal, developed technical online content for business websites, and developed and released open-source software for the Mac OS and Palm OS platforms. He has been a fan of Linux and XFree86 since 1994 and uses the software on Intel-based PCs, Apple PowerMacs, and MIPS platforms. Bill is an active member of the Northern Virginia Linux Users Group (NOVALUG); teaches Linux courses at Stratford University in Falls Church, Virginia; and lives in the Shirlington area of Arlington, Virginia. He can be contacted through http://www.tux.org/~bball. Hoyt Duff feels that a good word to describe his life experience is "former"—former senior vice president and senior commercial loan officer for a bank, former community college instructor, former restaurateur, and former special education teacher. He currently meets the needs of his inner ADD child by spending the summer months tending to his family business, a sport fishing pier (the longest on the East Coast), and playing cocktail piano on weekends. Hoyt even finds time to write about Linux as a columnist and regular contributor of reviews and tutorial for Linux Format magazine. Active in the TideWater Unix Users Group (http://www.twuug.org), Hoyt enjoys the regular Linux installfests the most and will attempt to install Linux on anything that moves.
