The -Free Software movement (which we'll get into in a moment) is working toward the goal of -making all software free of intellectual property restrictions. Followers of this -movement believe these restrictions hamper technical improvement and work against the -good of the community. The Open Source movement is working toward most of the same goals, -but takes a more pragmatic approach to them. Followers of this movement prefer to base -their arguments on the economic and technical merits of making source code freely -available, rather than the moral and ethical principles that drive the Free Software -Movement.</p> - -<p>At the other end of the spectrum are groups that wish to maintain tighter controls -over their software.</p> - -<p>The Free Software movement is headed by the Free Software Foundation, a fund-raising -organization for the GNU project. Free software is more of an ideology. The oft-used -expression is “free as in speech, not free as in beer”. In essence, free -software is an attempt to guarantee certain rights for both users and developers. These -freedoms include the freedom to run the program for any reason, to study and modify the -source code, to redistribute the source, and to share any modifications you make. In -order to guarantee these freedoms, the GNU General Public License (GPL) was created. The -GPL, in brief, provides that anyone distributing a compiled program which is licensed -under the GPL must also provide source code, and is free to make modifications to the -program as long as those modifications are also made available in source code form. This -guarantees that once a program is “opened” to the community, it cannot be -“closed” except by consent of every author of every piece of code (even the -modifications) within it. Most Linux programs are licensed under the GPL.</p> - -<p>It is important to note that the GPL does not say anything about price. As odd as it -may sound, you can charge for free software. The “free” part is in the -liberties you have with the source code, not in the price you pay for the software. -(However, once someone has sold you, or even given you, a compiled program licensed under -the GPL they are obligated to provide its source code as well.)</p> - -<p>Another popular license is the BSD license. In contrast to the GPL, the BSD license -gives no requirement for the release of a program's source code. Software released under -the BSD license allows redistribution in source or binary form provided only a few -conditions are met. The author's credentials cannot be used as a sort of advertisement -for the program. It also indemnifies the author from liability for damages that may arise -from the use of the software. Much of the software included in Slackware Linux is BSD -licensed.</p> - -<p>At the forefront of the younger Open Source movement, the Open Source Initiative is an -organization that solely exists to gain support for open source software, that is, -software that has the source code available as well as the ready-to-run program. They do -not offer a specific license, but instead they support the various types of open source -licenses available.</p> - -<p>The idea behind the OSI is to get more companies behind open source by allowing them -to write their own open source licenses and have those licenses certified by the Open -Source Initiative. Many companies want to release source code, but do not want to use the -GPL. Since they cannot radically change the GPL, they are offered the opportunity to -provide their own license and have it certified by this organization.</p> - -<p>While the Free Software Foundation and the Open Source Initiative work to help each -other, they are not the same thing. The Free Software Foundation uses a specific license -and provides software under that license. The Open Source Initiative seeks support for -all open source licenses, including the one from the Free Software Foundation. The -grounds on which each argues for making source code freely available sometimes divides -the two movements, but the fact that two ideologically diverse groups are working toward -the same goal lends credence to the efforts of each.</p> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="introduction-slackware.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="help.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">What is Slackware?</td> -<td width="34%" align="center" valign="top"><a href="introduction.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top">Help</td> -</tr> -</table> -</div> -</body> -</html> - |
