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. (1992-1996)
Stack-based (i.e. RPN) programmer's calculator for the command line, in the spirit of the Hewlett-Packard HP16C. Supports float, decimal, hex, octal, and binary modes, in varying word widths. Includes the usual trig and bitwise operators. Also a few unit conversions for good measure. (1993-2024)
Unix/linux support for the CP290 X10 home automation controller. (1994)
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 used it, running on a sunlight-readable laptop, when traveling by motorcycle, until I stopped riding a few years ago.. (2004-2017)
