I'll add things as they come, but the idea is to post useful geeky tools as they occur. So far, we have:
1. An application to help with jurabib (jureco) for LaTeX
2. An application that evaluates arguments for many-valued logics, and generates LaTeX-formatted truth-tables for them.
Both applications are released under the GNU General Public License.
Should you be interested, we also have the true story of my conversion to Dvorak (the Keyboard layout, rather than the composer), with a new appendix on my forays into Dvorak for Right-Hand. To supplement this, we have a new download (made with Ukelele):
3. A unicode Right Hand Dvorak keyboard layout for Mac OS X. (Place the file in User\Library\Keyboard Layouts. After a restart it will appear in the International options in System Preferences.)
