CODESH (COllaborative DEvelopment SHell) is an automatic persistent logbook for sessions of personal command line work. It records what and how is being done, for private use/reuse and for sharing selected parts with collaborators. It is an intelligent shell that automatically logs user's shell sessions. Sessions are uniquely tagged and stored in local or distributed backend repositories (ASCII flat file or Subversion or CVS based) and can be extracted and reproduced at any time by the user who created the session or by collaborators located anywhere in the world.
Podget is a simple podcast aggregator optimized for running as a scheduled background job (i.e. cron). It features support for downloading podcasts from RSS and XML feeds, for sorting the podcasts into folders and categories, for importing podcast URLs from iTunes PCAST files and OPML lists, automatic M3U and ASX playlist creation, and automatic cleanup of old podcasts. It also features automatic UTF-16 conversion for podcasts hosted on Windows servers.
ivata groupware is a groupware/intranet portal system based around J2EE standards. It provides an enterprise-ready solution. It is a great tool to enable teams to find contacts in team and private address books, to share documents, to post articles and notes, to comment on articles, to receive notifications via email, to plan meetings and other events in the calendar, and to access email via the Web.
PhotoFS is a Web-based photo album or image gallery, based on the files-as-directories and attributes-as-files concepts at the core of the ReiserFS 4 filesystem. It does not require ReiserFS 4, but is much more efficient on that system than on others. It does many of the same things as other Web galleries, at least as far as the basics go. What makes it different is its use of the filesystem instead of a database. It allows you to use regular unix tools to access your photo collection. It can handle very large collections, and also encourages multiple categories per file, deep category hierarchies, and batch processing.
