Beginning GIMP: From Novice to Professional is a guide to image editing using the GNU Image Manipulation Program (GIMP) for editing photographs and creating digital art.

Now out in its second edition.

The Linux for Presentations Howto, the Multiple Network Schemes Howto, information on Linux imaging, and more. Plus you can find quick Linux tips in my blog archive.

I give talks on a variety of technical and semi-technical subjects.

Programs I've written, including the pho image viewer and metapho image organizer, the Saver and Pandora GIMP plug-ins, PyTopo tiled map viewer, many little astronomy apps, Crikey for mapping strings to keys, assorted useful scripts, and plenty of other free open source software.

Or you can browse my Github repositories, including pho and metapho, pytopo, useful scripts and gimp-plugins, some of my dotfiles, and more.

I like to teach short courses in programming and technical subjects, such as summer workshops for high school girls in Robots and Sensors using Arduino and Javascript, and an online Python class.
