Internet Task Management System uses PHP to formalize the task delegation process in a business environment.
Functionality includes the ability to create individual tasks and then combine them into a process of work items which can be easily delegated to any user of the system.
Assignment and reminder emails are recieved based upon user preferences.
Administrators of the system have the ability to manage all users and their task properties. ITMS supports MySQL, Oracle, LDAP, and SSL.
Enhancements:
- Fixed bug where using 12 am or 12 pm would change the task date to 11/30/1999 (Bug# 749490)
-
- Also if the current hour of the day is 12, the task assign forms reflects the proper time now.
-
- The above code fixes were in task_assign2.php and task_pending_edit.php

Internet Chess ToolKit project is a Java library for chess with PGN, FEN, SAN, and ICS (FICS, ICC) support.
Internet Chess ToolKit is a Java-based set of libraries and widgets useful for performing common tasks such as reading SAN (internationalized), FEN, PGN, generating legal moves, and connection to Internet Chess Servers (FICS).
The purpose of the Internet Chess ToolKit is to provide an extensible library to facilitate the development of internet server clients, bots, training programs, peer-to-peer players, and and various other programs useful for the game player. The library was designed with a high level of abstraction and utilization of object oriented design patterns to make it extensible; The model set up should allow for implementations of many games besides Chess, which is the main focus of this library.
Such other games might include chess variants like BugHouse, or completely different games like scrabble and the Chinese game of Go. Another goal of the library is ease of use. A lot of effort has gone into comprehensive documentation and providing sensible names for methods, as well as providing many convenience methods.
Main features:
- FICS support (limited)
- legal move generation.
- game history with variation support (alternative move suggestions).
- move comment support in text and Numeric Annotation Glyphs (NAG).
- Standard Algebraic Notation (SAN) read/write support (internationalized for presentation in 16 languages).
- Portable Game Notation (PGN) read/write support (including move variations, and FEN).
- Forsyth-Edwards Notation (FEN) read/write support.
- True MVC structure with board displays driven by game model events.
- Command-line Board display (GUI to come).
- Well documented. Sample code also provided.
Enhancements:
- Limited FICS support style12, match request, kibitz, whisper, say, tell, channel tell, shout, c/t/-shout, emote, move list, pin, gin, seek ads, seek remove, seek clear, game results
- Timeseal support
- XSLT java code generation for ICS events
- Sample ICS Client
- PGN bugs fixed

Internet Relay Jabber (or IRJ) is a Jabber client for IRC. Its useful if you like IRC, but your friends use another IM service. Through Jabber, IRJ supports AIM, MSN, Yahoo!, ICQ, etc. It is written in Perl and uses Net::Jabber and Net::IRC.

Just to clear up any confusion, this isnt a transport or a gateway between Jabber and IRC (ie, a server component for many users). Is a program for connecting to IRC and Jabber simulataneosly. It then acts as an IRC bot to relay conversations in IRC to Jabber. It is meant for one user per IRJ process and pretty much requires a dedicated IRC channel. It also works best if you have access to a shell sever of some kind (so IRJ can always be running in the background) and use an IRC server with NickServ and ChanServ so you can restrict access to your IRJ channel.

That said, I personally find it very useful (though I may be biased because its my creation) because Im usually on IRC and dont like to have a bunch of other instant messaging programs open as well as my IRC client.

Debt Payment Comparison Calculator project is a free, flexible tool for your Web site that does more than just calculate monthly payments.
In addition to what typical Web calculators do, which is grab the principle, interest rate, and the years to pay it off to generate your monthly payment, this calculator can tell you how long it would take you to pay off a debt if you increased or decreased the payment amount.
Each time the user uses the calculator, it saves the information so that the user can compare different payment scenarios. At any time, the user can clear the data and start over. They can also color-group different scenarios for easy visual reference.
Main features:
- Stores calculations in a session variable, so users can compare different payment scenarios, side by side without the use of a database.
- Ability to color-code the scenarios by clicking on them, making it easy to visually sort the results
- Works fine without Javascript enabled
- Simple code to work with, easy to adjust to specific needs
- Styles and scripts are already in external files, making the web page search engine ready out of the box!
