Parsing RSS feeds
del.icio.us is a neat service for managing an online bookmark collection. With a little bit of Perl and a few CPAN modules, you can fetch your most recent bookmarks and include them as links on your homepage.
The sample script could be used in a cronjob and creates a file on you local server. It downloads my del.icio.us bookmark feed, chops it down to the ten most recent bookmarks and writes a unordered bullet list.
