hmmm. judging by the size of all my encryption keys and other security info, i'd still have 1.2MB left, at least.
my zettelkasten on the other hand takes up 2.8MB, so i'm thinking i'll have to go through that and pick out some of the most important entries. there's plenty of useless info though, so wouldn't be too hard. i'd estimate that'll take up another 5-600KB
so with ~600KB left, i guess might as well preserve my website. images and whatever aside, pure html is 180KB and the database is 416KB, so that would just about fill up the floppy. worst case scenario i can prune some of the less useful stuff.
