Free software is a matter of liberty, not price. Think of "free" as in "free speech," not as in "free beer." Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. Read more.


Free Software Definition

by 3 others
The Free Software Definition We maintain this free software definition to show clearly what must be true about a particular software program for it to be considered free software. Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech, not as in free beer. Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software: * The freedom to run the program, for any purpose (freedom 0). * The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this. * The freedom to redistribute copies so you can help your neighbor (freedom 2). * The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this. A program is free software if users have all of these freedoms. Thus, you should be free to redistribute copies, either with or without modifications, either gratis or charging a fee for distribution, to anyone anywhere. Being free to do these things means (among other things) that you do not have to ask or pay for permission.

Direct Rendering Open Source Project

The Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware under the X Window System in a safe and efficient manner. It includes changes to the X server, to several client libraries, and to the kernel (DRM, Direct Rendering Manager). The most important use for the DRI is to create fast OpenGL implementations. The DRI is an integral part of 7.x, and integrates with Mesa, an open source implementation of the OpenGL API. Several 3D accelerated drivers have been written to the DRI specification, including drivers for chipsets produced by ATI, Matrox, 3DFX, and Intel. The DRI was initially developed by Precision Insight, Inc. (PI) in cooperation with, and partially funded by Red Hat Inc., and SGI. Since PI's merger with VA Linux, and VA Linux' subsequent exit from Linux, the DRI is being maintained by Tungsten Graphics Inc., a new company formed by some of the initial DRI developers from PI. Tungsten Graphics is the current focal point for DRI development, and many open source developers continue to contribute to the project through the DRI project.


Links to Other Free Software Sites

To help promote knowledge of free software that isn't GNU software distributed by the FSF, we have collected the following links to other web sites that contain free software, or is directly related to the issue of free software. We do not have links to web sites of the well-known GNU/Linux system distributions, or to the well-known BSD system distributions, because all those sites explicitly describe, and facilitate access to, various non-free programs. We would be glad to know of other Free Software web sites that we could link to here.

The Free Software Foundation

Free software is a matter of liberty not price. The Free Software Foundation (FSF), established in 1985, is dedicated to promoting computer users' rights to use, study, copy, modify, and redistribute computer programs. The FSF promotes the development and use of free software, particularly the GNU operating system, used widely in its GNU/Linux variant.
