\section{History}

\subsection{The Journey}
\begin{frame}[allowframebreaks=0.6]
\frametitle{The Idea}
The Story so Far\ldots
\begin{itemize}
  \item Long process of thinking about the future for several years
  \item First idea with Kernel of MacOS X in Summer 2004
  \item First presentation of that idea at Developers Workshop 2005 in Dresden
  \item Reconsideration of this idea because it doesn't solve the main problem: Desktop
  \item New idea with OpenGL based Desktop with well known toolkits, developed at SYSTEMS fair in Munich
  \item Talks to various people and first presentation of that idea at
  Warpstock Europe 2005 in Dresden
  \item Presentation of first concept and design studies at Developers
  Workshop 2006 in Biel, Switzerland
  \item License decision during Summer 2006
  \item First 0.1 release of \textit{The Design of Voyager} released to the
  public for Warpstock Canada 2006
  \item Coding from various site, namely Chris Wohlgemuth on NOM
  \item Design studies for GTK+ on OS/2 by Dmitry
  \item Happy Hacking in Wintercamp 2007
  \item Preparation for Warpstock Europe 2007
  \item And then\ldots 
\end{itemize}
\end{frame}

\subsection{Uhm\ldots}
\begin{frame}
\frametitle{Along comes\ldots}
Daniela, and some more friends around us:
\begin{itemize}
  \item Why concepts from the nineties?
  \item Why a desktop concept based on mouse \& keyboard?
  \item What about the fancy new interfaces coming up (multitouch \& friends)?
  \item Why do I have to care about where I keep my information?
  \item Why do current desktops suck?
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{She Got a Point There\texttrademark}
That triggered some great discussions:
\begin{itemize}
  \item Why do we have to define how something gets represented?
  \item What would be an ideal world for handling our information?
  \item Is a mobile device also a platform for Voyager?
  \item Why implement old concepts?
  \item Who needs another desktop anyway?
\end{itemize}

\end{frame}

\subsection{The Outcome}
\begin{frame}
\frametitle{Later On}
Based on a SOM based core:
\begin{itemize}
  \item Workplace/Shell separation
  \item Semantic information on object level
  \item Binary compatibility
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Conclusions}
\begin{itemize}[<+->]
  \item A full blown Workplace is a nice goal
  \item but we need to start different
  \item Guerrilla tactics
  \item People won't care about NOM
  \item They care about what they get
  \item and about how they can work with it
  \item Divide and conquer 
\end{itemize}
\end{frame}

\section{Some Code, Anyone?}
\subsection{NOM}

\begin{frame}
\frametitle{Netlabs Object Model}
\begin{itemize}
  \item SOM is a binary compatible object model, no need to recompile objects (unlike on GNOME for example)
  \item There are some design documents from IBM itself (published in ACM)
  \item There is quite some documentation available written by former IBM employees
  \item Chris Wohlgemuth started to re-implement the concepts under the name NOM
  \item This is the technical base for our ideas
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Netlabs Object Model}
Things that work right now:
\begin{itemize}
  \item Binding files creation (IDL compiler)
  \item Class creation from IDL files
  \item Subclassing
  \item Method overriding
  \item Compiles on:
  \begin{itemize}
    \item eComStation
    \item MacOS X
    \item Linux
    \item Windows
  \end{itemize}
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Netlabs Object Model}
Thinks that do not work yet:
\begin{itemize}
  \item Class replacement, almost done
  \item Dynamical loading of classes, in development
  \item \ldots
\end{itemize}
Difference to SOM:
\begin{itemize}
  \item Use of an environment pointer in each method call (CORBA exception
  handling)
  \item SOM specific IDL extensions are not supported
  \item No distributed SOM
  \item Object pointer check
  \item \ldots
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Netlabs Object Model}
Things that will be implemented:
\begin{itemize}
  \item Signals and slots
  \item Getters/setters (properties)
\end{itemize}
\end{frame}

\subsection{Next Steps}
\begin{frame}
\frametitle{NOM}
\begin{itemize}
  \item Fix garbage collection on most platforms
  \item Code cleanup \& testing
  \item Build system improvements
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Workplace/Shell Separation}
\begin{itemize}
  \item First implementation
  \item Probably some RAD solution to start with
  \item Proof of the concept
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Webpages}
\begin{itemize}
  \item Some serious good looking page
  \item Information for developers
  \item Information for potential investors
  \item Information for users
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Developers}
\begin{itemize}
  \item Integration into development environments:
  \begin{itemize}
    \item Eclipse
    \item XCode
    \item VisualStudio
  \end{itemize}
  \item Walkthroughs for coders 
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Users}
\begin{itemize}
  \item Binary releases
  \item Basic features
  \item Integration into the supported platforms
\end{itemize}
\end{frame}
