+% Structuring a talk is a difficult task and the following structure
+% may not be suitable. Here are some rules that apply for this
+% solution:
+
+% - Exactly two or three sections (other than the summary).
+% - At *most* three subsections per section.
+% - Talk about 30s to 2min per frame. So there should be between about
+% 15 and 30 frames, all told.
+
+% - A conference audience is likely to know very little of what you
+% are going to talk about. So *simplify*!
+% - In a 20min talk, getting the main ideas across is hard
+% enough. Leave out details, even if it means being less precise than
+% you think necessary.
+% - If you omit details that are vital to the proof/implementation,
+% just say so once. Everybody will be happy with that.

+\begin{frame}{About the speaker}
+\begin{itemize}
+\item Programming computers since 1989
+\item Linux user + application developer since 1994
+\item Linux kernel development since 1999
+\item GNU GPL license enforcement since 2003
+\item IT security expert, network protocol security
+\item Board-level Electrical Engineering
+\item System-level Software for PPC, ARM, x86
+\item IANAL, but companies not complying with the license forced me to spend lots of time with legal issues
+\end{itemize}
+\end{frame}
+
+
+\section{Historical Development}
+
+\begin{frame}{Historical development}
+\begin{itemize}
+ \item 1970ies: Softare becomes copyrightable
+ \item 1980ies: GNU project, GPLv1
+ \item 1990ies: Linux kernel, GPLv2, servers
+ \item 2000s: Linux and FOSS is everywhere
+\end{itemize}
+\end{frame}
+
+\subsection{FOSS is everywhere}
+
+\begin{frame}{Linux and Free Software (FOSS) everywhere}
+\begin{figure}[h]
+\centering
+\includegraphics[width=100mm]{linux_netfilter_singapore_entertainment.jpg}
+\end{figure}
+\end{frame}
+
+\begin{frame}{More Linux - More License Violations}
+\begin{itemize}
+ \item Boom of Linux results in many {\em new companies} using it in products
+ \item Such Linux newbies do not have a history in the FOSS community
+ \item They also do not share the same culture, values and norms
+ \item They simply use Linux to reduce royalty cost for proprietary OS
+ \item They run into trouble (GPL violations)
+\end{itemize}
+\end{frame}
+
+\subsection{GPL enforcement}
+
+\begin{frame}{More License Violations - More Enforcement}
+\begin{itemize}
+ \item New Linux based products continue to enter the market
+ \item License compliance often very bad
+ \item Community is deeply upset about the violation of its rules
+ \item Often percieved as insult of the FOSS community culture
+ \item Lack of respect of corporations towards community
+ \item Legal enforcement is often the only possible way for community to educate corporations
+\end{itemize}
+\end{frame}
+
+\begin{frame}{GPL enforcement}
+\begin{itemize}
+ \item Before 2003: Mostly Free Software Foundation
+ \item 2003-now: gpl-violations.org (Europe), ~ 200 cases
+ \item 2005-now: SFLC (United States)
+ \item publicly invisible enforcement
+ \begin{itemize}
+ \item e.g. MySQL (dual-licensing)
+ \item e.g. Asterisk (dual-licensing)
+ \end{itemize}
+\end{itemize}
+\end{frame}
+
+\section{Beyond minimal license compliance}
+
+\subsection{FOSS communities vs. license terms}
+
+\begin{frame}{FOSS community is technical, not legal}
+\begin{itemize}
+ \item FOSS is created by software developers working together in
+colalborative ways, often without any formal structure
+ \item Individuals, Universities as well as Corporations
+contribute their work
+ \item Cooperation in a culture of sharing
+ \item Even direct competitors like Intel and AMD cooperate in Linux
+development, because everyone needs it
+ \item FOSS communities are deeply technical. They hate company
+politics.
+ \item License is {\bf just} a last resort of protection against
+those who absolutely don't understand FOSS
+\end{itemize}
+\end{frame}
+
+\begin{frame}{Beyond pure legal compliance with licenses}
+\begin{itemize}
+ \item Compliance with the legal terms of the license is the
+absolute bare minimum that companies have to do
+ \item If you use FOSS in your products, please consider
+establishing a healthy relationship with the communities that drive
+development of this software
+ \item It is not a customer / supplier relationship!
+ \item The community expects you to participate in development
+\end{itemize}
+\end{frame}
+
+\subsection{Becoming part of the community}
+
+\begin{frame}{Why should you join?}
+Benefits to Embedded electronics companies
+\begin{itemize}
+ \item Larger number of engineers can help you improve your product
+ \begin{itemize}
+ \item optimize performance (battery, speed, ...)
+ \item fix more bugs than your in-house R\&D
+ \item have more ideas/innovation than all engineers combined inside your company!
+ \end{itemize}
+ \item Be recognized within the community as {\em somebody who understands}
+ \begin{itemize}
+ \item allows you to attract skilled developers from the FOSS world who would otherwise never consider working for you
+ \item makes you more attractive to most technical customer base of {\em early adopters}
+ \end{itemize}
+ \item Reduce cost of maintaining your code base
+\end{itemize}
+\end{frame}
+
+\begin{frame}{How to become part of the community}
+\begin{itemize}
+ \item Permit your engineers to engage in technical discussions on mailing lists
+ \item Submit your modifications to the respective upstream projects
+ \item Join technical conferences and discuss technical issues
+ \item Encourage the community to innovate and extend your products
+\end{itemize}
+\end{frame}
+
+\begin{frame}{When and how to release source code}
+\begin{itemize}
+ \item Legal requirement:
+ \begin{itemize}
+ \item You're used to release source code at the time product ships because the license forces you to
+ \end{itemize}
+ \item Community norm:
+ \begin{itemize}
+ \item Your engineers interact with the project maintainers during R\&D
+ \item Source code of your modifications undergoes review + inclusion in mainline
+ \end{itemize}
+\end{itemize}
+\end{frame}
+
+\begin{frame}{Quality of the source code release}
+\begin{itemize}
+ \item Legal requirement / Reality:
+ \begin{itemize}
+ \item {\em complete and corresponding} source code
+ \item Often does not compile
+ \item Often contains proprietary kernel modules of questinable legality
+ \item Often provides no (simple) way of installing re-compiled program on the actual device
+ \end{itemize}
+ \item Community norm:
+ \begin{itemize}
+ \item {\em complete and corresponding} source code
+ \item no proprietary kernel modules that constrain e.g. updates to later kernels
+ \item complete utilities to install modified version of software on the device
+ \item maybe even some instructions on how to do so
+ \end{itemize}
+\end{itemize}
+\end{frame}
+
+\begin{frame}{Summary}
+\begin{itemize}
+ \item Show respect for the FOSS development model based on
+mutual respect and understanding
+ \item Actively engage and discuss with the community
+ \item Don't try to cheat your way out of license compliance
+ \item Treat community as partner in development of your products
+ \item Don't treat them like your enemy (DRM, Tivo-ization)!
+\end{itemize}
+\end{frame}
+
+\begin{frame}{Panel Discussion}
+\begin{itemize}
+ \item Thanks for your attention
+ \item We will now have a panel discussion on the subject of FOSS community interaction beyond license compliance
+ \item Contact me at \href{mailto:laforge@gpl-violations.org}{laforge@gpl-violations.org} with questions, feedback and comments
+\end{itemize}
+\end{frame}
