RoadMap
RoadMap is an open-source GPS tracking and map display program. I wasn't the original author, but I've spent a lot of time working on it. It can help the user follow a precalculated GPX format route, and can display maps from various sources, including the US census bureau's Tiger dataset, shapefile maps, and maps from Openstreetmap. The times, and technology, have caught up with it, however, and there are lots of other capable substitutes available. I still use it, running on a sunlight-readable laptop, when traveling by motorcycle.
vile
Finally, although I haven't worked on it in decades (!), I wrote the initial versions of vile, a vi-like text editor. It's been in the capable hands of Tom Dickey since I gave it up, and I'm still using it daily, even as I type these lines.
