+\slide{What is Free Radio?}
+
+My presentation at the GStreamer Conference 2019 in Lyon, France as the
+GNOME Radio developer and maintainer is about Civil Rights and Social 
+Action with Free Software.
+
+Live radio broadcasts covers events on every continent, every conflict, every human tragedy and triump in 
the world and Free Radio is about promoting news about human rights, peace and knowledge sharing between 
humans just like Free Software.
+
+The title of my Bachelor of Science thesis at Oslo Metropolitan University in Norway is ``Public Internet 
Radio Client for Accessing Free Audio Maps in Countries with Free Speech'' available from 
\url{http://www.oleaamot.com/thesis/thesis.pdf}
+
+GNOME Radio is the future Public Network Radio Software for Accessing
+Free Audio Broadcasts from the Internet on GNOME after 5 years of work 
+on GNOME Internet Radio (gnome-internet-radio-locator) since 2014 that
+began at Norwegian Computing Center in 2002.
+
+Live playback support implemented GStreamer is available in GNOME Radio.
+
+\slide{Introduction}
+\LogoOn
+
+GNOME Internet Radio Locator (gnome-internet-radio-locator) is a Free
+Software program that allows computer users to easily locate and
+listen to radio programs on broadcasters on the Internet such as BBC,
+KEXP and WMBR, as well as NASA's Third Rock Station and 107 other
+Internet Radio stations broadcasting from many universities around the
+world.
+
+GNOME Internet Radio Locator (gnome-internet-radio-locator) is
+developed for the GNOME 3.34 desktop and requires GStreamer
+(\url{https://gstreamer.freedesktop.org/}) and the codec plugins to be
+installed for live audio playback.  The player code was based on code
+from gst-play written by Tim-Philipp Müller, Sebastian Dröge and
+Brijesh Singh.  (See
+\url{https://gitlab.gnome.org/GNOME/gnome-internet-radio-locator/blob/master/src/gnome-internet-radio-locator-player.c})
+
+GNOME Internet Radio Locator (gnome-internet-radio-locator) is not
+officially a part of GNU or GNOME, but using the *.gnome.org
+infrastructure
+on\\ \url{http://gitlab.gnome.org/GNOME/gnome-internet-radio-locator}
+and\\ \url{https://download.gnome.org/sources/gnome-internet-radio-locator/}

+\slide{Why do I write gnome-internet-radio-locator?}
+
+\begin{list1}
+\item I am a supporter of
+  \begin{list2}
+  \item Free Radio
+  \item Free Software
+  \item Free Speech
+  \end{list2}
+\item I want to give something back to the Free Software community
+\item Internet Radio is a free Internet resource
+\item Many Universities run non-profit Internet radio stations
+\end{list1}

+
+\slide{What is the definition of Free Software?}
+
+From FSF's home page (\url{https://www.gnu.org/philosophy/free-sw.html}):
+
+\begin{list1}
+\item Free Software is a good idea because you have
+  \begin{list2}
+    \item The freedom to run the program as you wish, for any purpose (freedom 0).
+    \item The freedom to study how the program works, and change it so it does your computing as you wish 
(freedom 1). Access to the source code is a precondition for this.
+    \item The freedom to redistribute copies so you can help your neighbor (freedom 2).
+    \item The freedom to distribute copies of your modified versions to others (freedom 3). 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.
+  \end{list2}
+\end{list1}
+
+\slide{Existing Music Services}
+
+\begin{list1}
+\item Apple Music, Google Music and Spotify
+  \begin{list2}
+  \item Require non-free client software
+  \item DRM (Digital Restrictions Management)
+  \item Impose EULAs that restrict more than copyright
+  \item Track what the user listens to
+  \end{list2}
+\end{list1}
+
+One redeeming feature of some of them:
+
+\begin{list2}
+\item You can't access them from GNU/Linux at all.  If you're a GNU/Linux user, this protects you from the 
temptation to use them.
+\end{list2}
+
+\slide{Why did I write gnome-internet-radio-locator?}
