An intrepid user at the Ubuntu Forums has detailed the installation and setup of BlueProximity, a free Linux app that turns a Bluetooth phone into a proximity-based security device for your computer. Yes, that's exactly how it sounds: Your laptop locks itself down when you step a certain distance away, and opens again once you're in range.

This kind of measure is more utility than security device, and the instructions require serious attention (forgetting to undo one step could hose your system), but it's a nice privacy feature and seriously cool tweak at the same time.

The tutorial walks through the process on an Ubuntu system, but would likely help other GNOME-based systems get most of the way there.

The Linux community is known for its do-it-yourself ethic and extensive support forums, but sometimes a single voice with solid advice fits the bill. Over at homelinux.org, one kind soul has posted an extensive collection of free Linux-related PDF ebooks, covering topics ranging from installation and dual-booting to specific distribution tweaks and programming guides. The owner has instituted a 10-downloads-per-day quota, but the books are meaty enough to make that a non-problem. You could also consider donating a few dollars to the site if you find yourself downloading, say, the 1,400+ page Linux Bible and coming back for more.
