%Text in $ $ ist eine inline math-Umgebung, also mathematische Zeichen innerhalb einer Textzeile. Für Formeln in eigener Zeile: \[ \].
%"^" definiert immer Exponenten, obere Indizes etc., "_" untere Indizes.
%Griechische Buchstaben werden immer nach dem Schema \pi, \phi, \Pi... erzeugt, manche sehen mit \var schöner aus, z.B. \varphi
$\sum\limits_{i=1}^{3} i$ %Summenzeichen. \limits sorgt dafür, dass die Limits über und unter dem Summenzeichen stehen, nicht daneben.

* 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.

- Ben Klemens: Math you can't use

\section{Woher die Spiele nehmen?}
\begin{frame}[<+->]{Open-Source-Spiele}{Kostenloser, freier Spaß}
\begin{itemize}
\item Aus den Paketquellen
\item Von den Projektwebseiten
\end{itemize}
\begin{exampleblock}{Hinweis}
Einige Spiele haben eigene Repositories, so dass man Updates automatisch erhalten kann.
\end{exampleblock}
\end{frame}
\begin{frame}[<+->]{Open-Source-Spiele}{Kostenloser, freier Spaß}
Einige Open-Source-Spiele:
\begin{itemize}
\item FreeCiv - Ein Civilization Clone
\item SuperTux - Ein Jump and Rum Spiel
\item TuxRacer - Ein Rennspiel
\item Cube2: Sauerbraten - Ein Egoshooter
\item Scorched 3D - Ein 3D Actionspiel
\item Nexuiz - Ein Egoshooter
\item Warmux - Ein Worms-artiges Spiel
\item World of Padman - Ein Egoshooter
\item Stepmania - Ein Spiel ähnlich zu ``Dance Dance Revolution"
\item Frozen Bubble - Ein Puzzlespiel
\end{itemize}
\end{frame}
\begin{frame}[<+->]{Demos}{Kostenloses zum Anfixen}
\begin{itemize}
\item Von der Seite des Publishers
\item Hier auf der Veranstaltung (ich habe einen USB-Stick und dessen Inhalt auf diesem Rechner)
\end{itemize}
\end{frame}
\begin{frame}[<+->]{Von Distributoren}
\begin{itemize}
\item Spezielle Linux-Gaming-Seiten
\begin{itemize}
\item Desura \url{http://desura.com} (Das ist wie Steam, nur auch unter Linux verfügbar)
\item Indievania \url{http://indievania.com}
\item Gameolith \url{http://gameolith.com}
\end{itemize}
\item Humble Bundle
\begin{itemize}
\item Unregelmäßig und zeitlich begrenzt erscheinend.
\item Kollektion aus meist 4 oder mehr Spielen
\item Man kann den Preis selbst aussuchen
\item Die Spiele stehen dabei meistens (mir ist nur eine Ausnahme bekannt) für Linux, Windows und Mac zur Verfügung.
\end{itemize}
\end{itemize}
\end{frame}
\begin{frame}[<+->]{Emulatoren, DOS-Box, ScummVM}
\begin{itemize}
\item Mittels (Konsolen-) Emulatoren kann man auch alte oder nicht PC Spiele unter Linux spielen, z.B. ZSNES, mednafen, MAME
\item Mit DOS-Box kann man Spiele für DOS spielen
\item ScummVM ist eine Möglichkeit alte Adventures zu Spiele. Einige namhafte Beispiele sind ``Zak McKraken'' oder ``Day of the Tentacle"
\end{itemize}
\end{frame}
\begin{frame}[<+->]{Browsergames}
\begin{itemize}
\item BrowserQuest\\Ein HTML5 Fantasy-MMO von Mozilla (\url{http://browserquest.mozilla.org})
\item Diverse ``Aufbauspiele", z.B. Travian, OGame, Die Stämme, Siedler Online, etc\dots
\item Jede Menge Flash Spiele\dots
\end{itemize}
\end{frame}
\section{Windowsspiele mit Wine zocken}
\begin{frame}[<+->]{Was ist Wine?}{Wine is not an emulator}
\begin{itemize}
\item Wine ist eine Möglichkeit viele Windows Spiele unter Linux zu spielen
\item Wine übersetzt API-Aufrufe in eine für Linux verständliche bzw. ausführbare Form, also z.B. DirectX Befehle in OpenGl Befehle
\item Der Name Wine ist ein rekursives Akronym und bedeutet ``Wine is not an emulator".
\end{itemize}
\end{frame}
\begin{frame}[<+->][fragile]{Spielen mit Wine}{Wie geht das?}
\begin{itemize}
\item Ersteinmal das Spiel installieren: \verb+wine /pfad/zum/installer/setup.exe+
\item Danach das Spiel starten
\begin{itemize}
\item Starten der Desktopverknüpfung (sofern vorhanden)
\item Starten per Terminal/Konsole: \verb+wine ~/.wine/drive_c/pfad/zum/spiel.exe+
\end{itemize}
