I've used this script under both Win32 and OpenBSD to generate a plain-text file that I use for keeping a little journal of my thoughts.
<p>
I wrote it a long time ago (it's written in baby Perl) but have been using it monthly to make my journals, which are then really easy to edit and archive. I like keeping them in plain text format because then the entries are easy to cut and paste into other applications (emails, HTML forms, word processors, etc) without having to start a gigantic program or be online, etc.
<p>
I also like it because it simply writes a date for each day of the current month, like "Monday, July 14, 2003", with a few line breaks thrown in. That way, I can write down what I worked on that day, keep little notes or code snippets, lyrics, and so forth, and easily go back and review my month. And cross-platform date handling is a little trickier than I had initially expected, so I learned some things writing it, too.
<p>
Anyway, I know it isn't fancy, but since I use it every month, I figure somebody else out there might.
