Introduction
|
|
|
|
Background
|
|
|
|
In the 1960es software was always bundled to hardware and came in the source code
|
|
|
|
This didn't change very much during the 70s, because hardware was expensive
|
|
|
|
binary-only proprietary software became very strong in the early 80s

Richard Stallman
|

|
|
Experienced the early computing years at MIT AI labs
|
|
|
|
Was unwilling to give up the freedom he had through the source code
|
|
|
|
Had already written Emacs, the famos editor
|
|
|
|
Decided to do something against it in fall 1983

|
What is free software
|
|
|
|
According to Richard Stallmans definition, free software has the following freedoms:
|
|
|
|
Freedom to use the program for every purpose
|
|
Freedom to study how the program works and to adapt it to your own needs. Access to the source code is a precondition for this
|
|
Freedom to redistribute copies so you can help your neighbor
|
|
Freedom to improve the program and release the changes to the public, so that the whole community benefits. Access to the source code is a precondition for this.

Copyleft
|
|
|
|
Copyleft is a special enhancement to free software
|
|
|
|
Copyleft is defined by the GNU GPL (General Public License)
|
|
|
|
It adds certain distribution terms for the software and any derived work
|
|
|
|
If you redistribute a copylefted software to anybody, you license it including the sourcecode under the terms of the GPL
|
|
|
|
All derived work from the program is subject to the GPL, too.

|
Other free software licenses
|
|
|
|
Apart from the GNU copyleft free software license (GPL) there are some other non-copyleft free software licenses.
|
|
|
|
The BSD (Berkley Software Distribution) license and the XFree86 license are the best-known examples
|
|
|
|
These licenses don't protect the software from being used in proprietary software products.

Open source
|
|
|
|
|
|
Open source is a totally different ideology than free software.
|
|
|
|
The open source movement has the goal to produce stable software through availability of the source code to the public. Compare this to the aim of the free software movement: Freedom for all users.
|
|
|
|
Open source licenses may restrict publications of derived work as well as redistribution.
|
|
|
|
Please use the term 'free software' if you talk about linux and other projects licensed under the terms of the GPL or BSD license.
