I am not going to let these entries deteriorate to once-a-year!
I've had quite a fun time taking over hosting and maintenance for WEBoggle, a MMOCG (medium-sized multiplayer online cube-based game). The original author, Logan Ingalls, did an excellent job of designing the DHTML client and Perl server, but had to abandon it due to hosting issues. I adopted it, and rewrote the backend in Python (with SCGI) for performance and maintainability. Now I'm struggling to deal with all the travails (mis-cacheing, browser incompatibilities, etc) to which an online game is prone. If the game's players have half as much fun with it as I have coding it, then I had twice as much fun as they did!
I had read about geocaching, but never really investigated it. During a family visit in Boulder, CO a few weeks ago, my dad introduced us all to it, and took us out to find several caches in the area. Fun! The kids now want to continue geocaching here in Waco, and according to the website there are hundreds in our area.
