Project Steve Guttenberg is a PHP-driven diary/journal/blogging application that integrates seamlessly into an existing Web site. It provides many of the core features (including comments, trackbacks, RSS 2.0, tags, and searching) and administrative controls (all Web-based) of other, larger systems, but doesn't use a database, is XHTML 1.1-compliant and its look can be completely customized via CSS. It can easily be scaled to host several journal sites with a single installation.
Clan Admin is a Perl CGI script to administer a clan Website. It takes care of news pages, an active roster, a link manager, scheduled matches, match records, and personal bio pages. It is template-based and designed to work with any existing site design. It only requires access to Perl and SSI.
Drivel is a GNOME client for working with online journals, also known as weblogs or simply blogs. It retains a simple and elegant design while providing many powerful features, including support for LiveJournal, Blogger, MovableType, Advogato, and Atom journals. (Systems based off these are also supported, including WordPress and Drupal.)
vtticker is a Perl script that grabs pages from videotext/teletext (using alevt-cap) and transforms them to RSS, a form of XML which can be read by a variety of news ticker applications. Depending on the content of your TV station's videotext, it can present high-quality news and stock quotes on your desktop. Different subscripts are needed to support different TV stations.
Rippy the Aggregator is a lightweight RSS aggregator written in vanilla PHP. It downloads headlines from a configurable list of regularly-updated Web sites, and merges the items into a single list of all the latest news. Rippy could be used to keep track of several favourite sites, or as an automatic supply of filler material on a public Web site. It uses local files to store its persistent information, requiring no database and no non-default PHP library support.
