+
+# Introduction
+
+## Constats
+
+- la capitalisation des inventions (brevet) a concentré et centralisé les valeurs techniques
+- la mondialisation libérale des échanges a favorisé la dillution des produits capitalisés à grande échelle
+- le transfert de propriété s'établit selon une relation entre le coût intrinsèque de l'objet (lié au travail) et sa valeur symbolique
+- le droit d'auteur ou d'une marque constitue un vecteur de potentiel privatif
+- le numérique en mobilité a fait explosé les scénario d'usage et de tranfert des ressources et des valeurs
+
+## Objectifs
+
+- comprendre les réseaux, le développement participatif, le Web
+- définir l'open source et ses applications
+- localiser les communs numériques
+- établir une formulation de l'écologie numérique

+# Copyleft
+
+Le copyleft (🄯), parfois traduit comme gauche d'auteur, est l'autorisation donnée par l'auteur d'un travail soumis au droit d'auteur (œuvre d'art, texte, programme informatique ou autre) d'utiliser, d'étudier, de modifier et de diffuser son œuvre, dans la mesure où cette même autorisation reste préservée.

+# Licences
+
+## Logicielles
+
+- **Copyleft fort** : obligation de diffuser les œuvres dérivées sous la même licence, effet contaminant (GNU Public Licence, CeCILL A).
+- **Copyleft faible** : permet l’utilisation du code dans un cadre potentiellement non libre tant que les modifications sur le projet en lui-même sont rediffusées (LGPL, Mozilla Public Licence, CeCILL B)
+- **Non-copyleft** : licences permissives (MIT, BSD, Apache, CeCILL C)

+Si l'avènement des réseaux sociaux privés et centralisés a simplifié les communications inter-personnelles à l'échelle mondiale, il a dans le même temps limité les capacités des communautés humaines à définir par elles-même des outils numériques garantissant leurs libertés et leur autonomie. De la même manière, si les brevets devaient permettre de sécuriser les revenus liés aux droits d'auteur, les limites posées à l'exploitation libre des inventions fonctionnent comme des freins majeurs à l'innovation ouverte et au développement partagé. Cette conférence propose un tour d'horizon des concepts techniques et juridiques, des architectures et des usages du Web qui mettent en évidence l'intérêt des logiciels libres, des communs et des modes de décentratlisation en faveur d'une écologie numérique (on entend par là la définition d'une stratégie collective favorable aux activités humaines par l'intermédiaire de l'informatique mais qui en réduise la surface polluante, l'entropie et le rapport signal/bruit). L'exposé s'appuie sur de nombreux exemples et des cas d'usage courants comme la bureautique collaborative, la messagerie mobile et la diffusion musicale.

-#TimeSide
-
-## Python audio processing framework and server made for the web
-
-https://github.com/Parisson/TimeSide
-
-##Goals
-
-* **Process** audio fast and asynchronous with **Python**,
-* **Decode** audio frames from *any* audio or video media format into **Numpy arrays**,
-* **Analyze** audio content with some **state-of-the-art** audio feature extraction libraries like **Aubio, Essentia, Librosa, Yaafe, VAMP** and pure python processors
-* **Visualize** audio data with various fancy waveforms, spectrograms and other cool graphers,
-* **Transcode** audio data in various media formats and stream them through web apps,
-* **Serialize** feature analysis data through various portable formats (XML, JSON, HDF5)
-* **Playback** and **interact on demand** through a smart high-level **HTML5 extensible player**,
-* **Index**, **tag** and **annotate** audio archives with **cultural and semantic metadata**,
-* **Deploy** and **scale** your own audio processing engine flawlessly through any infrastructure with **Docker**

-### Use cases
-- **Upload** audio tracks
-- **Retrieve** audio tracks from remote providers
-- **Stream** original or transcoded sources
-- **Run** on-demand analysis
-- **Customize** processors parameters
-- **Collect** track's annotation to build audio corpora

-## RESTful API built on TimeSide
-👉 https://sandbox.wasabi.telemeta.org/timeside/api/
-
-### Server design
-- Based on Django REST Framework (DRF)
-- **Interoperability** between other servers or frontends and TimeSide instance and its data
-- Object-relational **database** in order to store music tracks and processing results
-- **Models**: define essential fields and behaviors of stored data
-- **queue-worker architecture** enables to run tasks asynchronously

-
-- `Item`: audio content and metadata (external id)
-- `Provider`: provide audio from a given plateform
-- `Selection`: list of items (corpus)
-- `Processor`: plugins with version and default parameters
-- `Preset`: processor and a set of parameters
-- `Experience`: list of presets forming a pipe (reproductible)
-- `Task`: an experience and a selection
-- `Result`: transcoded audio or numerical outputs (hdf5 file)
-- `Annotation`: label audio file on a given time or segment
