Cog is a themeable and modularized intranet homepage written in Perl. The aim is to make almost every aspect configurable via the Web interface to give the user the freedom of choice. It includes modules to search various search engines, add links, and display news items, and a simple todo list.
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.).
Checklinks is yet Another HTML Link Checker (in Perl 5). Features include SSI (.shtml) support, direct file reads where possible, HTML 4.0, HTTP 1.1, and aliases and other server options. Other useful but more common features include regular expressions to restrict the URLs searched and results reported, and a detailed verbose report. Checklinks was written with Apache in mind, and you can feed it your srm.conf file to auto-configure many settings.
Ciao is a complete Prolog system subsuming ISO-Prolog with a novel modular design which allows both restricting and extending the language. Ciao extensions currently include feature terms (records), higher-order, functions, constraints, objects, persistent predicates, a good base for distributed execution (agents), and concurrency. Libraries also support WWW programming, sockets, and external interfaces (C, Java, TCL/Tk, relational databases, etc.). An Emacs-based environment, a stand-alone compiler, and a toplevel shell are also provided.
cgi-util is a fast, easy to use C library for creating CGI programs. Functions are available for initialization (parsing), grabbing fields (by string, integer, double or boolean value), embedding HTML files, and more. It accepts both POST and GET request methods and has extensive error handling.
cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
