Here's another simple Perl program I thought I'd share. It's a very simple app for recording notes from the shell. As pasting the last one into WordPress didn't work too well, it's on my Dropbox account instead. I've used SQLite as the backend for the database (a no-brainer - I really like SQLite for little quick-and-dirty scripts like this) and it works pretty well.

At some point I may go back to this basic concept and expand on it a little - it would make sense to add a GUI to it, either by using a graphical toolkit such as Tk or turning it into a web app. I also like the idea of adapting it to use a non-relational database - something like CouchDB perhaps.
