ARSC Really Simple Chat is a Web chat system that uses PHP and MySQL. It works with every browser in existence, even text-based ones, and it uses the server push technique or, if possible, its own socket server. It is very simple to install and use ARSC. It includes some important features, such as operators, kick-ing, whispering, and more. Multiple rooms and different languages are available. To run ARSC on your site, you need a Web server that understands PHP, and can connect to a MySQL database.
pork is an ncurses-based AOL instant messenger client. It uses the OSCAR protocol (the one the Windows client uses) to access AIM. Pork features Perl scripting, an online help system, the ability to configure nearly all aspects of the program's look and feel, an alias system, and a powerful, fully configurable key binding system. It supports being logged in with more than one screen name at the same time. The default look and feel of the client is modeled after the ircII IRC client. Anyone comfortable using ircII (or any clients derived from it, e.g. epic, BitchX, etc.) will feel comfortable using pork.
