open sTeam project is an environment for cooperative knowledge management.

sTeam provides a technical platform which allows groups of students, lecturers, and any other groups to construct and arrange their individual and cooperative learning and working space.

It consists of an object-oriented server connected to a database, and Web, Java, and other (FTP, SMTP, IRC, etc.) clients.

The server is event-driven and manages all user objects as well as the communication between the connected clients.

Features that were different from most other cooperation tools is the self-organisation and self-administration by the members within the virtual environment.

Open Metaheuristic (oMetah) is a library aimed at the conception of metaheuristics (i.e. genetic/evolutionnary algorithms, tabu search, simulated annealing, ant colony algorithms, etc.). Open Metaheuristic library follows the "adaptive learning search" approach in the design of metaheuristics (an approach inspired from the "adaptive memory programming").
The oMetah core code design is separated in three components : algorithms, problem and communication. You can easily add your own metaheuristic and test it on the implemented problems, or add your own problem, and use the implemented metaheuristics to solve it.
You also have the choice of the way the algorithm and the problem are linked (static link, network, webservice, etc.).
It is mainly designed to handle continuous or mixed-integer problems, often met in engineering applications.
oMetah is written in C++, using the Standard Template Library.
Enhancements:
- The Python and network communication protocols between metaheuristics and problems are now usable.

OpenTaxSolver (OTS) project is a free program for calculating Tax Form entries and tax-owed or refund-due, such as Federal or State personal income taxes.
An optional graphical front-end, OTS_GUI, has been added. Currently, TaxSolver has been updated for the 2005 tax-year for the following forms: US 1040 and Schedules A, B, C, & D.
As well as for California, Massachusetts, New Jersey, and Pennsylvania State Taxes for 2005 tax-year, thanks to contributors. Updates for the following additional states are expected to be posted soon: North Carolina, New York, Ohio, and Virginia. Preliminary versions for Canada and the United Kingdom were posted in previous years and may be updated with help from volunteers.
Motivations:
- To make tax preparation software available for all platforms.
- To provide insight into how our taxes are calculated in clear unambiguous equations/code.
- To avoid invasive, bloated commercial software packages.
- To avoid rewriting our own individual programs each year by combining efforts.
- To provide a simple reliable tax-package requiring only rudimentary knowledge to maintain.
Enhancements:
- Automatic phone credit was added to US1040.
- It will automatically calculate standard one-time phone credit, if not otherwise specified on US1040 line 71.
- The NJ State form F line 5 was fixed.

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.

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 necessary if movie plays with delays on direct opening.

After watching movie you may delete copied file by click Yes on dialog box.

Installation instructions:

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

This is an excellent widget set for Tcl which retains much of the Tk syntax, but uses curses to render the widgets in a character-cell terminal instead of X and a graphical display.

Installation

1. Type "./configure". This runs a configuration script made by GNU autoconf, which configures Ck for your system and creates a Makefile. The configure script allows you to customize the configuration to your local needs; for details how to do this, type "./configure --help" or refer to the autoconf documentation (not included here).

The following special switches are supported by "configure":

--enable-shared If this switch is specified Ck will compile itself as a shared library if configure can figure out how to do this on this platform.

--with-tcl Specifies the directory containing the Tcl binaries and Tcls platform-dependent configuration information. By default the Tcl distribution is assumed to be in "../../tcl8.0".

2. Type "make". This will create a library called "libck.a" or "libck8.0.so" and an interpreter application called "cwsh" that allows you to type Tcl commands interactively or execute scripts.

3. Type "make install" to install Cks binaries, script files, and man pages in standard places. Youll need write permission on the install directories to do this. If you plan to install the libraries, executables, and script files whitout documentation, use "make install-binaries" and "make install-libraries".

4. Now you should be able to execute "cwsh". However, if you havent installed Ck then youll need to set the CK_LIBRARY environment variable to hold the full path name of the "library" subdirectory. If Ck has been built as shared library, you have to set the LD_LIBRARY_PATH to include the directory where "libck8.0.so" resides.

So far, Ck8.0 has been successfully tested on various Linux distributions, on FreeBSD 3.3 with manually adapted Makefile, and on Windows NT 4.0 with a modified PDCURSES library. The Ck8.0 source tree should be able to be combined with Tcl7.4, 7.5, 7.6, and 8.0. Older version of Ck (which use Tcl7.4 or Tcl7.5) are in use for several years on HP-UX, AIX, and DEC Unix.
