* Introduction
** Overview
- Understanding software
- What are the four freedoms of free software?
- What's the difference between Open Source and Free Software?
* Considerations about Software
- Source Code is a work of authorship, similar but not identical to
works of literature, a cooking recipe, or a musical piece.
- Side Note: Legally, works of authorship fall under Copyright.
- Some form of Instruction set to make a machine do something.
- Condensed knowledge, or information (hence IT).
* Considerations about Knowledge
- Information has unique, properties, it is not a real commodity and
it cannot easily be contained.
- From an economic point of view, knowledge is a positive externality.
- Software, like all knowledge, should be accessible in a democratic
and nondiscriminatory way.
* Intellectual "Property"?
- Umbrella term for copyright, patent, trademark and other
categories law. Those have virtually nothing in common.
- Commonly misused to actually mean anything.
- Implies claim to ownership, in particular of ideas.
* Market implications
- In a free market economy monopolies are ususally dangerous and have
to be avoided.
- Monopolies on public goods are really, really bad.
- Software still generates economic value; however, most is generated
by use, not sale of software.
- Software patents are in effect monopolies on ideas.
* The Four Freedoms
** Freedom 0
- You are free to run the program, for any purpose.
- Not as obvious as it might seem.
** Freedom 1
- You are free to study how the program works, and change it so it
does your computing as you wish. Access to the source code is a
precondition for this.
- The user controls the software, not the other way around.
** Freedom 2
- You are free to redistribute copies so you can help your neighbor.
- Few people realize how important sharing is, in particular sharing
of public goods. Contrary to common propaganda, ideas, techniques, stories,
melodies, images etc. are NOT hurt by sharing. On the contrary,
sharing keeps them alive.
** Freedom 3
- You are free to distribute copies of your modified versions to
others. By doing this you can give the whole community a
chance to benefit from your changes. Access to the source code is a
precondition for this.
* Open Source?
Openness of source is less decisive when one or more of the four
freedoms are formally or effectively taken away.
The term "Open Source" is usually used synonymous to Free Software, in
the past the term was coined to avoid misunderstandings.
* Licensing
** GPL
- Copyleft, restrictive, enforces all four freedoms.
*** BSD
- Non-copyleft, permissive, not all rights have to be conserved.
- Perversion Software Patente: Wie etwas, das eigentlich Innovation foerdern soll genau das Gegenteil bewirkt.
- Digital Restrictions Management (DRM):
- Defective by Design und Malicious Features. Beispiele: Amazon Kindle, ei-Phone, Skype, Spotify, Steam, Diverse unfreie Betriebssysteme
- Probleme mit restriktiven Datenformaten: MP3, flash, docx, etc...
