+\begin{frame}{Brought to you by the Deuxfleurs association}
+
+\begin{block}{\textbf{deuxfleurs.fr} -- a libre hosting association with a vision}
+``Shifting the current structure of the Internet from a world of a few very large service providers, to a world where services are hosted by a variety of smaller organisations.''
+\end{block}
+
+
+\begin{block}{Our goals}
+\begin{itemize}
+ \item To propose performant \& reliable libre services for the masses
+ \item To host and administer our infrastructure ourselves
+ \item To allow members to contribute storage/compute nodes
+ \item Resilience: for availability \& the sysadmins' sleep
+ \item Conceptual simplicity to ease onboarding \& demistify hosting
+\end{itemize}
+\end{block}
+
+
+\end{frame}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\begin{frame}{The lacking state of the practice}
+
+\begin{block}{Object storage fitted our needs}
+\begin{itemize}
+ \item Distributed by design
+ \item Objects are replicated
+ \item Conceptually simple
+\end{itemize}
+\end{block}
+\vfill
+
+\begin{block}{Existing object stores did not}
+ \begin{itemize}
+ \item Too specific / complex
+ \item Resource hungry
+ \item Hidden constraints
+ \end{itemize}
+\end{block}
+\vfill
+
+We developed Garage, an object store with minimal functionality.
+
+It works, and serves our static sites and media.

+\begin{itemize}
+ \item Distributed data store
+ \item Based on DynamoDB object store (P2P!)
+ \item Modular data types/protocols with CRDTs:
+ \begin{itemize}
+ \item Done: objects (media, static sites, backups...) via S3 API
+ \item To do: e-mails via IMAP protocol, and more

+ \textbf{Pros:}
+ \begin{itemize}
+ \item Compiled and fast
+ \item Features prevent usual mistakes:
+
+ strongly typed, immutable by default, ownership instead of GC...
+
+ \item Best of several paradigms:
+
+ imperative, OO, functional
+
+ \item Good libraries for network programmings:
+
+ serialization, http, async/await...
+ \end{itemize}
+\column[t]{.4\columnwidth}
+ \textbf{Cons}:
+ \begin{itemize}
+ \item Steep learning curve
+ \item Long compilation times
+ \item Compiler rage
