Net::Server is an extensible, generic Perl server engine. Net::Server combines the good properties from Net::Daemon (0.34), NetServer::Generic (1.03), and Net::FTPServer (1.0), and also from various concepts in the Apache Webserver.
Net::Server attempts to be a generic server as in Net::Daemon and NetServer::Generic. It includes with it the ability to run as an inetd process (Net::Server::INET), a single connection server (Net::Server or Net::Server::Single), a forking server (Net::Server::Fork), a preforking server which maintains a constant number of preforked children (Net::Server::PreForkSimple), or as a managed preforking server which maintains the number of children based on server load (Net::Server::PreFork). In all but the inetd type, the server provides the ability to connect to one or to multiple server ports.
Net::Server uses ideologies of Net::FTPServer in order to provide extensibility. The additional server types are made possible via "personalities" or sub classes of the Net::Server. By moving the multiple types of servers out of the main Net::Server class, the Net::Server concept is easily extended to other types (in the near future, we would like to add a "Thread" personality).
Net::Server borrows several concepts from the Apache Webserver. Net::Server uses "hooks" to allow custom servers such as SMTP, HTTP, POP3, etc. to be layered over the base Net::Server class. In addition the Net::Server::PreFork class borrows concepts of min_start_servers, max_servers, and min_waiting servers.
Net::Server::PreFork also uses the concept of an flock serialized accept when accepting on multiple ports (PreFork can choose between flock, IPC::Semaphore, and pipe to control serialization).

Papercut NNTP Server is a news server written in 100% pure Python. It is intended to be
extensible to the point where people can develop their own plug-ins and by that integrate the NNTP protocol to their applications.

The server is compliant with most of the RFC0977 standards (when they make sense and are needed) and implements a lot of RFC1036 and RFC2980 extensions to the NNTP protocol. It was tested against Netscape News, Mozilla News and tin (under Solaris) and it works properly.

The original need for this server was to integrate my PHP related web site forums with an NNTP gateway interface, so people could list and read the messages posted to the forums on their favorite News reader.

At first it wasnt intended to support message posting, but it made sense to allow it after seeing how effective the tool was.

The concept of storage modules was created exactly for this. I would create a Python
class to handle the inner-workins of Phorum and MySQL and if I ever wanted to integrate the server with another type of software, I would just need to write a new storage module class.

Anyway, back to the technical praise. Papercut NNTP Server forking-based on UNIX platforms and should be reasonably fast (that means basically: its pretty fast, but dont try serving 1000 connection at a time).

The best thing about the application is that it is very simple to extend it.

C++ Server Pages is a partial Java server pages and servlet implementation in C++. C++ Server Pages is written as Apache 2.0 modules, with the focus on performance.

Unix I-Ching Generator project is an I Ching generator for the Unix command line.
It accepts questions and generates responses that can be looked up in the I Ching (a Chinese divination book).
It is designed around "spiritual algorithms", that is, algorithms that make some sort of sense spiritually, not just programatically.
This is software that automates the casting of I-Ching hexagrams. It does not provide the interpretations or readings of those hexagrams.
It merely outputs a mandella of two hexagrams and then informs you of the numerical identity of each hexagram.
Enhancements:
- Moved global options to header file. (ARJ)
- Changed unigram::cast() so that it relied on globals. (ARJ)
- Fixed spelling errors. (ARJ)

Web-Based Adult Content Server is a suite of programs which manage photo sets and video clips of an adult nature.
It runs on a home Linux/Unix server and creates a personalized adult Web server in which to store, preuse, and catalogue a personal collection of adult material.
Web-Based Adult Content Server has many features, like model catalogs, attribute-based searching, randomized highlights, new addition lists, and a flexible bookmark mechanism.
Enhancements:
- This release has new features and many bugfixes.
- It includes a new Web-based Model Manager application, locations-based filtering (e.g. Bathroom), and a new connections infrastructure for galleries and ad-hoc collections.
