+* Introduction
+** Overview
+- Understanding software
+- What are the four freedoms of free software?
+- What's the difference between Open Source and Free Software? 
+
+* What is 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.
+
+* Free Software Economics
+** Market implications
+- In a free market economy monopolies are usually seen as 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.
+
+* Examples of Licensing
+** F/OSS Licensing 
+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. 
+*** GPL
+- Copyleft, restrictive, enforces all four freedoms.
+*** BSD
+- Non-copyleft, permissive, not all rights have to be conserved.
+
+* Conclusion
+** On Flash
+Flash is not actually secret but adobe keeps making new versions which
+are different, faster than anyone can keep up and make free software
+to play those files, so it has almost the same effect as being secret.
+
+** On non-free formats
+It's bad to distribute recordings in mp3 or any other proprietary
+format. Although there is free software to handle those formats,
+distributors legally can not include support for such formats because
+they are patented in many countries. Modern distributions of GNU/Linux
+facilitate use of these formats by letting the user decide, thereby
+avoiding legal issues. Whether or not this is a good thing is a
+question of moral. On the one hand, many of these formats have become
+pseudo-standards and for most users, the short term usability aspect
+prevails. On the other hand, it's a very bad idea if we were hoping to
+get rid of proprietary formats eventually.
+
+
+** Wrap-Up
+- If you want to support freedom, don't distribute recordings in
+  non-free formats. Please use formats such as .ogg, .webm, or .png.
+
+- In an epoch when governments work for the mega corporations instead
+  of reporting to their citizens, every technological change can be
+  taken advantage of to reduce our freedom.

+IP-Addressen: \textbf{IPv4}
+
+
+Addressvergabe: \textbf{DHCP} -- automatisch

+Private Addressen -- ``per Hand`"
+
+\begin{itemize}
+\item 192.168.0.0 - 192.168.255.255
+\item 172.16.0.0 - 172.31.255.255

+Theorie im \textbf{IPv4}
+\begin{itemize}[<+->]
+\item Netzwerkblock: 192.168.x.y \textbf{/24}

+\begin{itemize}[<+->]
+\item Netzwerk: 192.168\textbf{.43}.y
+\item Rechner: 192.168.\textbf{43}.1 -- 192.168.\textbf{43}.254
