++\subsection{About monolight}
++
++\begin{frame}{Monolight implementation}
++High-level details:
++\begin{itemize}
++\item Python ≥ 3.5 (pondering ≥ 3.6);
++\item Fully async (using \texttt{asyncio} with the stream API);
++\item Fully typed, it's great;
++\item Very slow, no tests \Neutrey;
++\item Uses Artem Popov's \texttt{pymonome} library;
++\item 2/3 months of work, GPLv3.
++\end{itemize}
++\pause
++\vspace{1em}
++It's really just the beginning, lot of fun stuff:
++\begin{itemize}
++\item More UI features;
++\item UI animations;
++\item Control other things.
++\end{itemize}
 +\end{frame}

++\only<1>{%
++The ``parent'' project:
++\vspace{1em}
++\begin{itemize}
++\item C99, libevent2, CMake --- that's all;
++\item Daemon, low memory footprint, fast enough\footnote{A bit of a CPU consumer.};
++\item 32/64 bits, big/little endian, FPU optional;
++\item Runs on nearly everything but Windows\footnote{LXSS will fix that though?};
++\item First PoC in 2014, mostly written through 2015;
++\item GPLv3 with non-GPL users in mind.
++\end{itemize}
++}
++\only<2>{%
++Original ideas:
++\vspace{1em}
++\begin{itemize}
++\item Remove discovery delays and glitches;
++\item While exposing a high-level \emph{vendor agnostic} API;
++\item While offering network isolation;
++\item No cloud nor Internet required;
++\item ``Accessible''.
++\end{itemize}
++}
++\only<3>{%
++Implementation details:
++\vspace{1em}
++\begin{itemize}
++\item Uses LIFX's faster and \emph{harder} LAN API;
++\item Proxies all communications to the bulb;
++\item Keeps track of the \emph{current} state of the bulbs (sampling);
++\item High-level API in JSON-RPC over TCP, Unix sockets or a named ``command'' pipe\footnote{The pipe is unidirectional: only usable to send commands.};
++\item Very good modular C, unit-tests, good docs.

++\item ``State-enforcement'';
++\item Effects API and effects plugins;

++\begin{frame}{Not on my roadmap}
++Things I wanna have:
++\vspace{1em}
++\begin{itemize}
++\item JSON-RPC extensions: streaming, auth, server notifs;
++\item A reversed-engineered LIFX firmware;
++\item A firmware that doesn't crash;
++\item Support for other bulbs;
++\item Color calibration;
++\item LIFX stripe support.
