DESCRIPTION ^
The Jabber::Connection package provides basic functions for connecting clients and components to a Jabber server.

The CAN Abstraction Layer (CANAL) provides a single interface for programs to use different CAN drivers.
It consists of a CANAL daemon that handles client and driver communication, a canalLogger that logs messages in a window, and a simple diagnostic application. C++ clases and DLL/DL interfaces are provided.
Enhancements:
- The configuration readings for CanalWorks were upgraded.
- A GUID ordering problem in canald was fixed.
- A problem with clear message list switch in CanalWorks was fixed.
- A problem in which Linux version Level I received a thread with an invalid count returned for DataAvailable was fixed.

Online Cardgame System project is a client-server system for playing card games over the net.
OCS is a client-server cardgame system, similar to those found at Yahoo! Games and elsewhere. The server is portable and has been tested under Linux, Win32, and several unix systems. We currently have Win32 and Java clients available, and a Qt client for Linux is in development.
Games are implemented as plugin modules, so new games can be added without recompiling the server. In addition, the client is written to be unaware of the mechanics of gameplay, so it can theoretically play any games the server supports without having to know how to play them specifically.
We currently have Euchre and Spades implemented, with bot support for both games, meaning you dont need a full 4 people to play a game. We plan on implementing more games in the future.
On a side note, development of this project tends to wax and wane with our motivation and amount of schoolwork.
Enhancements:
- Massive restructure of code into more object orientated patterns
- Added daemon capability to server
- Got rid of checksumming in the protocol since TCP/IP does it internally
- Padded STRINGS in the protocol on DWORD boundaries
- Added support for loadable account managers
- Removed crypting of the password by ocsd (account managers may do it)
- Added ODBC (for windows) and mySQL (for unix) account managers (database connectivity!!)
- Modified packet classes to throw exceptions instead of returning true-false
- Created packet manager classes to queue client packets, reduces total send calls
- Implemented bots when there arent enough people to play games
- Added new command line processing capabilities as well as configuration file support
- Fixed bug that allowed a person to overwrite an account when creating that same account
- Win32 - Made server link with DLL runtime library to reduce executable size and ease DLL dependencies
- Updated messages to be sent in HTML since the main clients support it
- Created Java client which can be run as an application or as an applet
- After a client is booted from a game, they cannot join the game again until they receive an invitation
- Fixed libtidy bug which caused it to erroneously format HTML
- Euchre supports intelligent bots
- Spades supports moronic bots (the AI is horrible but allows for gameplay)
- Fixed Spades textual problem when a round was over.
- Fixed Spades score calculation that resulted in no loss of points
- Win32 client now supports HTML (IE4+ required)
- Win32 client can now join games by right-clicking on an empty game slot in the game view.
- Fixed major bug in Win32 client that would cause it to crash when sending private messages
- Win32 client can now use /msg to send private messages

Netwatch is a Linux program created to aid in monitoring Network Connections. It is based on a program called "statnet" but has been substantially modified for its Ethernet emphasis. The project is a dynamic program which displays the Ethernet status based each the connections activity.
It has the capability of monitoring hundreds of site statistics simultaneously. The connections port number (Well Known Service) and destination address are available as well. There are options which allow router statistics to be measured on simple networks (with one router). External network communication is counted and transfer rates are displayed.
Main features:
- Reload feature for periodic saves and clears
- Routing Summaries with character graphics display
- Saves of Routing Statistics for last day of run (min. by min.)
- Freeze display (continue logging) for remote efficiency
- PPP Connectivity Monitoring
- Multiple Interface Support (1 at a time)

Argus Monitoring System software is a system and network monitoring application.
It will monitor nearly anything you ask it to monitor (TCP + UDP applications, IP connectivity, SNMP OIDS, Programs, Databases, etc).
It presents a nice clean, easy to view web interface that will keep both the managers happy (Red Bad. Green Good.) and the techs happy ("Ah! thats what the problem is").
It can send alerts numerous ways (such as via pager) and can automatically escalate if someone falls asleep.
Main features:
- It is open-source available at no charge.
- It has a clean and intuitive web interface.
- The web pages can easily be understood by non-technical people.
- It can generate graphs of what is going on.
- It can monitor network connectivity (Ping test)
- It can monitor TCP/UDP ports
- It can monitor a wide variety of TCP/UDP applications (HTTP, SMTP, RADIUS, ...)
- It can monitor the output or exit code of a program (Program test)
- It can monitor the content of a web page (such as a shopping cart application)
- It can monitor the authoritativeness of a nameserver
- It can monitor SNMP OIDs (such as BGP status, UPS voltage, room temperature, ...)
- It can monitor the results of SQL queries
- It can monitor itself.
- It can be extended to monitor things that the author didnt think of
- It can notify someone (or many people) when something happens
- It can escalate, and notify someone else, if things dont get fixed.
- It can not alarm for known downtime (maintenance overrides)
- It will summarize and rate-limit multiple notifications to prevent paging-floods.
- It keeps historical statistics, for analysis or SLA verification.
- It scales well and can monitor many, many things.
- It can restrict users to viewing only certain items (user "views")
- It can restrict users access to certain features (access control)
- It can support IPv6.
- It can support SNMPv3.
- It can support l10n for your native language.
- It can support redundant multi-server configurations.
Enhancements:
- This release offers improved performance and scalability, adds support for additional tests, and adds support for failover and redundancy.

SOPE Application Server is an extensive set of frameworks (16 frameworks, ~1500 classes) which form a complete Web application server environment.
Besides the Apple WebObjects compatible appserver extended with Zope concepts, it contains a large set of reusable classes: XML processing (SAX2, DOM, XML-RPC), MIME/IMAP4 processing, LDAP connectivity, RDBMS connectivity, and iCalendar parsing.
The individual frameworks of the package can be used standalone (for example in Cocoa applications) and do not require the application server itself.
For MacOSX developers, the package includes SOPE:X, which contains special Xcode and Cocoa support for SOPE.
Enhancements:
- This release fixes a set of minor bugs.
- It improves the vCard parser, the IMAP4 client library, the MySQL adaptor, and BSD packaging.
