Feeling a bit like a Thermian? Never give up, never surrender! Someday, you could go from underdog to top dog. Just take a look at a few of the underdogs we highlight in this issue: Mutt, djbdns, Nginix, Gentoo, Xara and the program voted mostly likely to fail just a few years back—Firefox. If Firefox not radical enough for you, check out Chef Marcel's column for some more alternatives. Having trouble mapping your program data to your relational database? If so, Rueven Lerner shows you some tricks in his At The Forge column.

Need to run GUI applications on your server in the next state? In his Paranoid Penguin column, Mick Bauer shows you how to do it securely. Kyle Rankin keeps hacking and slashing and shows you a few split screen secrets you may not be familiar with. Finally, we all know what happens next February, but only Doc knows what happens afterward.
