Comment 3x5 index card (Score 1) 221
Seriously. For my latest project, I've been using 3x5 index cards, and I'm OK with it. Sure, it's not web-based, but it seems to be working OK.
My evolution of personal bug tracking: first, I used a text file. What I didn't like about that was that I couldn't sort it. So, I moved to a spreadsheet. I really liked that. But, it's probably my CVS background, but I'm still uncomfortable checking in non-text documents into a version control system. I guess I could save it as a CSV to get around that uncomfortableness. But, now I've started using 3x5 index cards.
Index cards are nice and small, easy to transport (if you don't have too many bugs), and easy to sort. When I find a bug or think up a new feature, I just write out an index card and stick it in the appropriate place in the pile. I keep mine sorted by priority, and they are very easy to re-arrange. And for version control, I just keep around the cards that I've completed in a separate pile.
I would NOT want to do this for a large project, but for a personal project, it's working great so far.
