Got an old iPaq laying around that you’re not using? Or perhaps you have one and just want to get your new favorite OS (Linux, of course) onto it? Then check out this IBM DeveloperWorks article and, as the subtitle says, “put a penguin in your pocket.”
The author covers installing the Familiar Project distro, but doesn’t get too far into connecting to the Internet and/or getting around the operating system. However, he does provide plenty of resources, and of course you could always drop by TuxMobil for more information.
