-+\pdfnote{% Notes:
-+- Monolithic approach to solve the problem;\
-+- Est-ce que l'argument de l'isolation fonctionne ou IoTivity le résoud aussi?\
-+- Je ressens pas le besoin d'investir dans plus de domotique donc que lightsd\
-+  soit restreint ne me dérange pas, puis la stabilitité m'arrange;\
-+- Ce qui peut faire la différence avec IoTivity c'est la documentation, en
-+  bonus un plan pour vraiment extend;\
-+- Tu peux aussi dire: « voilà, moi j'ai fais ça, je sais pas trop comment\
-+  fonctionne IoTivity et les autres projets, mais si vous avez été déçu, venez\
-+  jeter un coup d'œil. »\
-+- Interfaces are bad because they encourage inheritance, I believe composition\
-+  is a better design pattern. (Though you can't really say the \"mixin\"\
-+  approach is composition, it really is inheritance, like interfaces, in the \
-+  sense that it delegates all attributes of the composite object).\

-+\begin{frame}{Being a daemon}
-+\pdfnote{%
-+Pros:\
-+\
-+- Instant devices ``discovery'';\
-+- Conflict resolution;\
-+- Good network location.\
-+\
-+Cons:\
-+\
-+- Applications aren't self-contained: side-car process though, or even tighter\
-+  if you're GPLv3;\
-+- Discovery: avahi? dns?\

-+\pdfnote{%
-+I think this is a pretty obvious idea, avoid getting locked with one\
-+manufacturer or product.\
-+\
-+lightsd has been architectured around a minimal set of bulb commands, meaning\
-+that while abstractions/integrations are missing to make lightsd work with\
-+other bulbs, it at least relies on a very limited set of commands (get/set\
-+the state of the bulb and that's about it). For example lightsd can totally\
-+implement transitions internally.\
