About the Author
Brian Tiemann is a freelance technology columnist and software engineer who has operated his own business and leisure websites on FreeBSD servers since 1995. As an outspoken advocate for the Apple Macintosh platform as well as for FreeBSD, he values a synthesis between open-source and closed-source development, and believes FreeBSD and Mac OS X both validate that synthesis for the benefit of all users. Brian is a graduate of Caltech, author of Mac OS X Tiger in a Snap and iPod + iTunes for Windows and Mac in a Snap, and coauthor of Sams Teach Yourself FreeBSD in 24 Hours.
