Crabgrass is social networking, group collaboration, and network organizing Web application. It consists of a solid suite of group collaboration tools such as private wikis, task lists, a file repository, and decision making tools. Work is currently being done on a large user interface overhaul, better social networking tools, blogs, and event calendars, as well as better support for collaboration and decision making among independent groups.
Octave daemon is a network daemon for GNU Octave, implemented in PHP. The package also contains a PHP client for connecting to the daemon. Native PHP applications can also use the connector class to run ad hoc Octave instances, circumventing the daemon altogether (which can be useful for development or small projects).
