Got a USB thumb drive? I’ve mentioned Tiddlywiki before, the clever little self-contained wiki that consists of a single html file. It’s continued to evolve and gotten its own domain/website. A new version recently shipped. This is a handy way to carry data you have to have around with you – simply copy the file to your thumb drive and load it up at whatever computer you happen to be sitting in front of. There’s also a modified version called GTDTiddlyWiki based on the ‘Getting Things Done’ model of productivity management, if you’re interested in such things. Neither is really a replacement for a full-fledged wiki engine, but if you’re looking to test the waters or you just need something simple that’s slightly better than a sticky or emailing yourself reminders, one of them might be a good fit, and they’re painless to check out.
