Frameworx project (on Tigris)
We opensourced all our code when the Frameworx company was shut down in 2004. I wrote most/all of the model engineering code in Louis, the model-driven ORM (Object-Relational Mapping) component. This is also where Buckminster was born, a build automation tool that matured and migrated to become part of the Eclipse eco system.
Social Music Discovery Project (on Github)
This is/was an open source project where we aimed to extend the Logitech Squeezebox server with social interaction capabilties. I co-designed the data model and wrote the Eclipse-based rich client, Yggdrasil. Unfortunately, Logitech terminated the Squeezebox product line before we were able to launch anything really useful (we had an alpha version running as a plugin for the server).
p2rplaylister (on sourceforge)
A command line tool for automatically generating MP3 playlists from ID3 tags. I wrote this to overcome a restriction in my first media streamer, the Turtle Beach Audiotron, which didn't read ID3 v2 tags with multiple genres. I still use it, but haven't maintained it for quite some time. It just runs.
p2r network connection monitor (on sourceforge)
Intended to detect and log WAN outages to help end users troubleshoot problems and discuss availability with ISPs. Currently just an embryo, plan to evolve it to make it work at least for my personal use.
p2r-foxport (on Github)
A simple command-line tool for automatically exporting Firefox and Chrome bookmarks to HTML.
Development is not only about code. Again, most of my sketches and writings are proprietary, but some are online:
