CUPS is a standards-based printing system for Mac OS X and other Unix-like operating systems. It provides the System V and Berkeley command line interfaces, and uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality. CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real world printing.
CommPort is a community portal system based on Perl and MySQL. Each user gets a personal portal page to which they can add their own "channels" or select from a growing list of pre-prepared local, national and international content. This allows any individual to always have a page of their own personal favourites in front of them. Channels may be either "active" with continually updated weather or news headlines or "passive" with collections of links. Each user can publish channels they've created for other users to incorporate into their own Portal. Locally created channels (administrated by a web-based interface) are also available in standard RSS/RDF format for integration with any other RSS aware system (e.g. MyNetscape, MyUserland, etc.).
Conflux allows the user (through the PHP-based frontend) to submit searches to be performed on common search engines. Searches are performed by a Perl-based backend and results are stored in a database (usually MySQL). Using Conflux, you can manage your past searches, better keeping track of materials you have found useful, and aiding you in submitting follow-up searches. Both searches and search results may be bundled together, permitting you to best organize your information how you see fit.
