I bought a cheap GPS on EBay. I got a Palm Vx with a Magellan GPS Companion attachment for ten dollars. By PDA standards the Palm Vx is completely obsolete, but it works fine as a GPS data logger.

I've recently come across two interesting projects and web sites: openaerialmap.org and openstreetmap.org. These two projects are efforts to collect and share freely-available map information.

I have participated in contributing electronic books to Project Gutenberg (2003).

I have also been working on several online encyclopedia projects:

• Editing Wikipedia, an open-content free encyclopedia (2001-4). See my contributions.

I have contributed towards Project Gutenberg and Distributed Proofreaders (2003).

I've contributed computing time to distributed computing projects such as

• Folding@home. See My stats

I did make it into rec.humor.funny with this joke

From 1993 through 1998 I hosted a number of mailing lists for free at bolis.sf-bay.org and later bolis.com.

I have contributed to a number of Internet software projects.

Majordomo mailing list manager: I wrote the "get" and "index" commands, and the "archive.pl" and "autobounce.pl" programs (1994). They are now community-supported (in other words, I've forgotten everything so I can't help much on them anymore...)

Ghostscript: I wrote the Imagen imPress laser printer driver (1992).

I've been working on Wikipedia. See my Wikipedia page
