jiggyMPD is a Web-based client for the Music Player Daemon and a companion tray icon. It is in relatively early development, but usable now. jiggyMPD extends the MPD data to add features MPD clients typically lack, such as ratings, date added, and last played date. This allows for some unique features. The jiggy data can be queried for smart playlist-type functionality. For example, "added <= 30, rating = 0, playcount <= 2, lastplayed > 1" will tell the client to find all songs added to your collection within 30 days, not yet rated, played 2 or less times, and not played today. It also fetches album art and lyrics.
Hailo is a fast and lightweight markov engine intended to replace AI::MegaHAL. It has a Mouse (or Moose) based core with pluggable storage, tokenizer, and engine backends. It is similar to MegaHAL in functionality. The main differences (with the default backends) are better scalability, drastically less memory usage, an improved tokenizer, and tidier output. With this distribution, you can create, modify, and query Hailo brains. To use Hailo in event-driven POE applications, you can use the POE::Component::Hailo wrapper. One example is POE::Component::IRC::Plugin::Hailo, which implements an IRC chat bot.
e-Photogallery is a Web-based photo gallery. It supports very large galleries and large files. Archive files (zip, rar, gzip, bzip2, tar) can be used for uploading photos. Most bitmap formats are supported, as well as SVG, PS, PDF, and EPS. Whole photo folders can be downloaded in various output formats and sizes. Other features include searching, tagging of photos and folders, and online resizing of thumbnails, and extensive control of access rights. EXIF data is read and used.
Callstats collects and displays call statistics for Siemens HiPath OpenOffice ME in a pretty Web interface. It may work with other Siemens HiPath devices (probably Hipath 3000). With some modifications, it could be adapted to your own system. It has 3 parts: -tcp->text log (via netlog); text log->sqlite database (PHP script); and a Web interface to the SQLite database (PHP). It has been tested without problems in a 50-user installation fulltime since 2009.
selfoss is a multipurpose RSS reader, live stream, mashup, and aggregation Web application. You can register RSS feeds, and this Web-based PHP application will continuously fetch new RSS feed items.

Attaching new sources is very easy, and you can add any source you want (e.g. IMAP email account, log files, etc.). selfoss also allows you to collect all your postings on different communities (e.g. Twitter, your blog, etc.) and show it in one place. It features a Web-based RSS reader, universal aggregator, mobile support (Android, iOS, and iPad), and support for MySQL, SQLite, and MongoDB databases. It is easy extensible with an open plugin system (write your own data connectors). It is a lightweight PHP application taking up less than 2 MB.
