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 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 Journal Systems (OJS) is a journal management and publishing system that has been developed by the Public Knowledge Project through its federally funded efforts to expand and improve access to research.
Main features:
- OJS is installed locally and locally controlled.
- Editors configure requirements, sections, review process, etc.
- Online submission and management of all content.
- Subscription module with delayed open access options.
- Comprehensive indexing of content part of global system.
- Reading Tools for content, based on field and editors choice.
- Email notification and commenting ability for readers.
- Complete context-sensitive online Help support.
OJS assists with every stage of the refereed publishing process, from submissions through to online publication and indexing. Through its management systems, its finely grained indexing of research, and the context it provides for research, OJS seeks to improve both the scholarly and public quality of referred research.
OJS is open source software made freely available to journals worldwide for the purpose of making open access publishing a viable option for more journals, as open access can increase a journals readership as well as its contribution to the public good on a global scale (see PKP Publications).

Open Partly Copied is a service menu (+ shell-script included) allows by one-click start copying video file from remote storage to local directory and immediately open partially copied file with your default player.

Its easy. Archieve containts install.sh script. So extract archieve to temp directory and run install.sh

Open Project Services (OPS) is a project collaboration platform, integrating server components such as e-mail, calendaring, timesheets, documents, knowledge, etc. with standards complient clients. Open Project Services consists of a project server and a set of client extensions.
We are building a project collaboration platform. It consists of a project server that integrates with services needed within a project, e.g. e-mail, calendaring, timesheets, documents, knowledge, etc.
The project server is a Webservices hub based on Java (J2EE). The persistence layer for project information is LDAP. We use OpenLDAP now, but others should also be possible. The e-mail backend makes use of a standard IMAP server. Our reference implementation uses Courier.
We are building extensions/plugins for clients, making them OPS-enabled. We support e.g. Mozilla Thunderbird (XUL) and Squirrelmail (PHP) for e-mail clients. For the calendaring and timesheet components we have a Mozilla Sunbird extension (XUL).
In short: we are building a project collaboration environment on an OSS stack, enriching services with project information, using COTS clients/servers and open standards.
Enhancements:
- This release includes some changes to the underlying LDAP schema to make it possible to disable tasks when they are completed.
- To make use of this new feature, the Web services and the sunbird timesheet client have to be updated.

Open Simp-X provides a scalable Internet management platform.

Open Simp-X is a powerful Internet platform for everyone, attempting to change programming for the Internet with sharing database information. It strives for scalablility, reliability, and ease of use.

The platform consists of a client/server pair. Security is a top priority, and data transfers are encrypted. Open Simp-X achieves scalability through plugins.

Plugins can collect information, manipulate it, and send it back to the database. Writing plugins is easy since they do not have to worry about how to send or receive their information, and can focus on manipulating it.

Open Simp-X can be set up to retreive data through a LAN or through a Web server.
