The main features include visual network monitoring, an enhanced network topology designer, email alert, trap receiver, trap agent, and real time logging to DB and Web.

Open LMS project consists of a learning management system.
OpenLMS is a Learning Management System (LMS) made at the Department of Geography, NTNU.
The system is a fully functional LMS with support for group collaboration, file sharing, distribution of lectures, and other supporting features.
It is a good tool for distributing lecture notes to groups of students, and for facilitating collaboration for groups of students and teachers.
The system has successfully been used at the Dept. of Geography at NTNU in Trondheim Norway, for three years. It is continuously further developed and was released as OpenSource software last year.
OpenLMS now supports English (core language) and Norwegian. Steps has been taken to translate for further languages.
Scorm, Dublin Core, AICC etc. could be important factors in systems like OpenLMS and similar LMS/LCMS. Support for exporting objects for these standards will probably be incorporated into OpenLMS. HOWEVER - the focus of standards for the exchange of learning objects often overshadows the lack of a culture for sharing within the organizations in question.
This very resource-demanding part of a LMS/LCMS is therefore not focused at the present stage in the development.
Main features:
- upload lecture notes (any filetypes)
- distribute levture notes
- groupware / email to groups
- personal file archive
- assignment administration
- media archive and termbank
- organize webresources
- language support for norwegian, english and german (may easily be extended)

Open BEAGLE is a C++ Evolutionary Computation (EC) framework. It provides an high-level software environment to do any kind of EC, with support for tree-based genetic programming, bit string and real-valued genetic algorithms, and evolution strategy.
The Open BEAGLE architecture follows strong principles of object oriented programming, where abstractions are represented by loosely coupled objects and where it is common and easy to reuse code.
Open BEAGLE is designed to provide an EC environment that is generic, user friendly, portable, efficient, robust, elegant and free.
With Open BEAGLE, the user can execute any kind of EC, as far as it fulfills some minimum requirements. The only necessary condition is to have a population of individuals to which a sequence of evolving operations is iteratively applied.
So far, Open BEAGLE supports most mainstream EC flavors such genetic programming, bit string and real-values genetic algorithms, and evolution strategy. It also includes support for advanced EC techniques such multiobjective optimization and co-evolution.
The user can take any of these specialized frameworks and modify them further to create his own specialized flavor of evolutionary algorithms.
Main features:
User Friendliness
- Considerable efforts were deployed to make the use of Open BEAGLE as easy and pleasant as possible. Open BEAGLE possesses several mechanisms that offer a user friendly programming interface. For example, the memory management of dynamically allocated objects is greatly simplified by the use of reference counting and automatic garbage collection. The programming style promoted is high-level and allows rapid prototyping of applications.
Portability
- The Open BEAGLE code is compliant with the C++ ANSI/ISO 3 standard. It requires the Standard Template Library (STL). No specific call in the core libraries are made to the operating system nor to the hardware.
Efficiency
- To insure efficient execution, particular attention was given to optimization of critical code sections. Detailed execution profiles of these sections were done. Also, the fact that Open BEAGLE is written in C++ contributes to its overall good performance.
Robustness
- Many verification and validation statements are embedded into the code to ensure correct operation and to inform the user when there is a problem. Robust mechanisms for periodically saving the current evolution state have also been implemented in order to enable automatic restart of interrupted evolutions.
Elegance
- The interface of Open BEAGLE was developed with care. Great energy was invested in designing a coherent software package that follows good OO and generic programming principles. Moreover, strict programming rules were enforced to make the C++ code easy to read, understand and, eventually, modify. The use of XML as file format is also a central aspect of Open BEAGLE, which provide a common ground for tools development to analyze and generate files, and to integrate the framework with other systems.
Free Sourceness
- The source code of Open BEAGLE is free, available under the GNU Lesser General Public License (LGPL). Thus, it can be distributed and modified without any fee. (See section copyright for further details.
Enhancements:
- Several fixes to allow compilation on Mac OS X
- Fixes in headers inclusion to allow precompiled headers

Open Tranquera is a repository of reusable components for J2EE application development.

There are UI extensions, Services, and a Persistence layer, integrated with existing open source frameworks.

Open Site Builder Tools is a project that provides you with free software intended to facilitate your life as a professional web site developer.

Currently available tools include:

open site builder

site pages assembler. Merges content pages into a predefined template and produces target site by only replacing changed documents. Now includes sitemap generator

osb log analyzer

scans osb logs and displays list of modified files day by day, version by version. Each day activity is divided by project version and each version displays modified files sorted in descending order by the number of times the file was modified. So you can simply review development activity in each project version and know which files were most active

osb ftp uploader

uploads site pages from your development machine to the production server. Only the newer documents are uploaded. It also shows you the files on your target server that are missing in your development environment. This facilitates you the task of tracking moved / deleted files

Open Tax Solver GUI is an optional Graphical User Interface for all Open Tax Solver programs and tax-form versions. It provides a simple way to enter and edit your tax-data and to run the tax-solver on it. The OTS GUI is written to work with any OTS tax data file, both past, present, and future. It is a modular addition to the OTS program set.

The OTS GUI contains no specific tax-form data itself, but rather it reads your selected tax-form file and configures itself accordingly. By virtue of OTS-GUI, all OTS versions now automatically have a GUI front-end, and anyone, even without GUI-writing experience, may create new tax programs having this graphical front-end.

The OTS_GUI is written in C using the Otk (Open Tool Kit) graphics library. It appears to compile easily and run properly on all platforms, including Linux, Microsoft Windows, Mac OsX, Solaris, Irix, and other Unixs in general. Otk was chosen for its cross-platform support, simplicity, and smallness. The OTS GUI is a single C file having less than a thousand lines, and the Otk library consists of a few small files.
