Free freely software for linux

Speak Freely is an application for Unix and Unix-like systems (Linux, FreeBSD, IRIX, etc.) with audio hardware, which allows you to talk (actually send voice, not typed characters) over a network. Speak Freely for Unix uses the workstation audio hardware and network to allow conversations of users over the network.

The phone company never gives you a break! You pay a fortune for a leased line connection to the Internet, and you *still* have to pay every time you want to chat with somebody, even though youre both sitting in front of workstations with digital audio capability, linked by a fast network. Speak Freely for Unix can intercommunicate with

Workstations on local area networks can generally communicate with excellent audio quality and response. A software implementation (developed by Jutta Degener and Carsten Bormann, Technische
Universitaet Berlin) of the compression algorithm used in GSM digital cellular telephones allows operation over Internet links of modest bandwidth. By using GSM compression in conjunction with sample interpolation, the data rate can be reduced to about 9600 baud. Users with CPUs too slow or two heavily loaded to perform GSM compression and decompression in real time may select less compact but quicker to
execute ADPCM coding, using an implementation developed by Jack Jansen of the Centre for Mathematics and Computer Science, Amsterdam, The Netherlands.

XFree86 is an open source X11-based desktop infrastructure.

The XFree86 Project, Inc is a global volunteer organisation which produces XFree86, a freely redistributable open-source implementation of the X Window System since 1992.

XFree86 runs primarily on UNIX and UNIX-like operating systems like Linux, all of the BSD variants, Sun Solaris both native 32 and 64 bit support, Solaris x86, Mac OS X (via Darwin), SGIs Irix as well as other platforms like OS/2 and Cygwin.

What XFree86 does, is provide a client/server interface between the display hardware (those physical things like the mouse, keyboard, and video displays) and the desktop environment, (this is typically called a window manager as it deals with how X is displayed i.e. the overall appearance).

Yet X it goes beyond that and also gives the infrastructure and a standardized application interface (API). All of this, makes XFree86 platform-independent, network-transparent and extensible.

Crafty is a state-of-the-art computer chess program. The project is full-featured, plays a good game of chess, and source code is freely available.
Enhancements:
- Many changes since the last update.

JRoller provides a rollercoaster simulator.
It is intended to be mainly entertaining and not scientific.
The track and many physical variables are automatically generated from a number of fulcrums freely placeable.
The application does not make use of any 3D acceleration and should run on any decent Java-enabled browser.
Some fulcrum points define the track which is interpolated between them ("periodic cubic spline" for the experts). The fulcrums can be changed in realtime. Try it out and let me know, if something goes wrong.
Version restrictions:
- This file contains the source code and the compiled class files of jRoller. I apologize for the lack of documentation, but I think its not that complicated. If you want to improve or modify the source code, feel free to ask me any questions about the code. You need a Java compiler to build it, and the Java Runtime Environment to run it.

phppdflib is a class written in php that presents an easy to use API for generating PDF files dynamically.
Main features:
- Its freely licensed under the GNU GPL.
- Since its written in php, it doesnt require you to recompile or reconfigure your web server in any way
- Since its written in php, its platform independent. It will run on any system that supports php, such as Windows, Linux, Macintosh, and BSD.
- Its specifically designed to allow easy programming for text processing applications (such as reporting)

Jeceira provides an implementation of JCR (JSR 170).
Jeceira is an implementation of JCR, the Content Repository for Java Technology Specification (JSR 170).
Its goal is to create a freely available, fast, and extensible layer for various content dependent applications to build upon.
Enhancements:
- Observation implemented
- Configuration of UUID generator simplified (no jug-native directory required)
- Node.orderBefore revised (including changes in the database schema)
- Bugfix in saving items (new items could be saved by calling save on them)
- Bugfix in counting of changes pending in a session
- Package item refactored
- Dependency on commons-0.1 changed to commons-0.2 due to a bugfix in the
- commons module

Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively.

More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine.

For instance, it allows one to freely run Linux on Windows 2000/XP, without using a commercial PC virtualization software such as VMware, in a way which is much more optimal than using any general purpose PC virtualization software.

In its current condition, it allows us to run the KNOPPIX Japanese Edition on Windows.
