\subsection{The history of Open-Source}

\end{frame}

\begin{frame}
\frametitle{Understanding the history}
\begin{itemize}
\item Open-Source is not a new idea
\item In the early days of big server systems it was common to deliver the source
\item The HW manufacturers only did the HW
\item Customers basically had to do bugfixing on their own
\item There was no business model behind the Operating System Software
\end{itemize}
\end{frame}

\begin{frame}
\begin{figure}[h]

\end{figure}
The computer market changed and components became exchangable. So did
Operating Systems.
\end{frame}

\begin{frame}
\frametitle{Change of the business model}
\begin{itemize}
\item Companies changed their business model and Operating Systems turned into
products
\item Also the most common UNIX Systems became proprietary
\item So, people using UNIX now had to pay just to use their
existing software
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{The FSF}
\begin{itemize}
\item In 1983 Richard Stallman founded the Free Software Foundation
\item He announced to implement a Free UNIX and to give it for free to anyone who wants to use it
\item So, he also implemented a licensing model
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{The FSF}
\begin{itemize}
\item The FSF was quite successful in implementing a lot of tools
\item But they didn't finish (even not until today) their operating system (GNU HURD)
\end{itemize}
\end{frame}

\subsection{The story of Linux}

\begin{frame}[fragile]
\frametitle{Linux enters the scene}
\begin{verbatim}
Hello everybody out there using minix -

I'm doing a (free) operating system (just a hobby,
won't be big andprofessional like gnu) for
386(486) AT clones.  This has been brewing 
since april, and is starting to get ready.
\end{verbatim}
Linus Torvalds (1991 / Minix newsgroup)
\end{frame}

\begin{frame}
\frametitle{Linux}
\begin{itemize}
\item Linux was implemented as a UNIX derivative / clone
\item In 1992 Linux was relicensed under GPLv2 (the license designed by the FSF)
\item Now, the Linux Kernel and the available tools from the FSF resulted
in a completely free UNIX!!
\item That was the start of a big success story
\end{itemize}
\end{frame}

\subsection{Free Software}

\begin{frame}
\frametitle{Misunderstandings about Free Software}
One of the main questions asked about Free Software is: How can I earn
money with a software if it's free?
\end{frame}

\begin{frame}
\frametitle{Misunderstandings about Free Software}
\begin{itemize}
\item The most popular explanation of Free Software is: ''Free as in FREEdom
and not as in free beer...''
\item It gives you the FREEDOM to use, study and re-distribute it.
\item You can charge for the re-distribution!
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{More misunderstandings about Free Software}
Another common misunderstanding is, that software which is published as
Open-Source is not copyrighted:
\begin{itemize}
\item Licensing and Copyright are two different things!
\item For sure: Also Open-Source software is copyrighted!!!
\item It's just licensed under a Open-Source license!
\end{itemize}
\end{frame}

\subsection{Why using Open-Source}

\begin{frame}
\frametitle{Focus on your knowledge}
\begin{itemize}
\item Concentrate on the things which are "unique" to your product
\item For the ''rest'' co-operate with others
\item We call this Open-Innovation (which is neither a new idea)
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{What makes your product unique?}
You have to define the level of your specific know-how:
\begin{figure}[h]
\centering
\includegraphics[width=7cm]{images/knowhow.jpg}
\end{figure}
\end{frame}

\begin{frame}
\frametitle{Faster time to market}
\begin{itemize}
\item Focussing on your knowledge results in a faster ''time to market''
\item Sharing common things with others results in faster innovations
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Open Innovation also results in:}
\begin{itemize}
\item Lower costs
\item Faster development
\item Better products
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Flexibility}
\begin{itemize}
\item Huge choice of ex-changable componentes
\item You can do adjustments on your own
\item You can build the know-how on your own
\item You can work with MANY contractors and you're not bound to one manufacturer
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{How Open-Source changed business}
\begin{itemize}
\item Over the years companies more and more took advantage of Open-Source
\item Companies adjusted to the benefits of Open-Source
\item Many modern business models just won't work without OSS (just think
about Social Media and Web Services)
\item So, Open-Source became also commercially driven
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Free Software vs. Open-Source}
...or the shift in terminology.
\end{frame}

\begin{frame}
\frametitle{Free Software vs. Open-Source}
\begin{itemize}
\item The idea of Free Software was originally based on the FREEDOM of using
software
\item A lot of explanation was needed for the term ''Free Software''
\item During the 90s the term Open-Source was created
\item This shift in the terminology also reflects the commercial success
\end{itemize}
\end{frame}

\subsection{A different mindset}

\begin{frame}
\frametitle{But, ...}
Open-Source also adds some complexity!
\end{frame}

\begin{frame}
\frametitle{Formerly you had...}
\begin{figure}[h]
\centering
\includegraphics[width=7cm]{images/contract_work.jpg}
\end{figure}
\end{frame}

\begin{frame}
\frametitle{With Open-Source you have...}
\begin{figure}[h]
\centering
\includegraphics[width=7cm]{images/oss_integration.jpg}
\end{figure}
\end{frame}

\begin{frame}
\frametitle{It's faster, it's cheaper, it's more flexible...}
...but it doesn't come for free!
\end{frame}

\subsection{How to use Open-Source}
\begin{frame}

\frametitle{Adopt to this mindset!}
Working with Open-Source is mostly "integration work":
\begin{itemize}
\item So, you need a common process for integrating OSS software
\item You need to understand which quality assurance is done by the
community and what needs to be done on your own
\item You need a concept for maintaining the software
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Setting up an Open-Source program in your company}
\begin{itemize}
\item License compliance
\item Selecting components
\item Maintaining components 
\item Community Participation
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Selecting and packaging components}
\begin{itemize}
\item Define a responsible team / person for selecting new OSS components
\item Define clear criterias for acceptable OSS components
\item Build a database for existing components in your company
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Maintaining components}
\begin{itemize}
\item Define a responsible team / person for maintaining existing components
\item Setup processes for bugfixes, security updates and change requests
\item The ideal case is having some kind of ''internal linux distribution''
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{How will these processes help}
\begin{itemize}
\item Share bugfixing amongst projects (do not underestimate this advantage!!!)
\item Speed-up estimations for new projects
\item Speed-up license compliance topics
\item Reduce the overhead of maintaining the components
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{What can you do to participate}
\begin{itemize}
\item Well, ''participate'' ;-)
\item Sponsoring
\item Hiring
\item Conferences (presentations, ...)
\end{itemize}
It's always good to be known and accepted by the community / communities.
\end{frame}

\begin{frame}
\frametitle{Why should I participate?}
It's always good to be known and accepted by the community / communities!
\begin{itemize}
\item Bring in your own interests
\item Getting support from the community
\item Push back changes and bugfixes to hand-over maintainance to the community
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Now, ...}
...let's get the hands dirty and implement the processes...\\
But, don't forget: Before implementing processes you have to
define a strategy and derive adequate policies.
\end{frame}
