+# "Event Horizon": Lot 2 21/06/2023
+### JOLY Amaury (Laboratoire d'Informatique et Système, Parsec)
+### __Encadrants:__ Emmanuel GODARD, Corentin TRAVERS (Equipe Algorithmique Distribuée)
+
+---
+
+# Rappel des objectifs
+
+--
+
+## Pour Parsec
+
+__Lot 2 :__ Ajout à Parsec d'un outil d'édition collaborative.
+
+Dans approche visant à maximiser les performances (latence et interactivité) et la résilience.
+
+--
+
+## Pour le LIS
+
+Produire de la recherche sur la cohérence faible en milieu byzantin.
+
+--
+
+## La synthèse des deux
+
+1. Faire un état de l'art des solutions existantes.
+    - Prendre des décisions sur les choix techniques à adopter.
+2. Recherche d'un compromis algorithmique __résilience__/__intéractivité__.
+3. Réaliser un produit innovant dans sa gestion de la cohérence.
+    - Chercher une valeur ajoutée pour l'utilisateur.

+## Quelques définitions
+
+__Cohérence dans un système reparti:__  
+Étude du comportement des données dans un système reparti d'un point de vue observateur.
+
+__Cohérence forte :__  
+Comportement attendu dans le cas d'une exécution à un seul acteur.

+
+## État de l'art
+
+- Cohérence dans les systèmes répartis.
+  - Lamports (1970)
+  - Perrin : Concurrence et Cohérence des Systèmes répartis (2017)
+

+## État de l'art
+
+### Un (très) rapide résumé
+
+<img src="./img/cartographie_simplifie.png" alt="cartographie des critères de cohérences" height="250"/>
+
+- Les critères de cohérences s'articulent autour de 3 propriétés élémentaires.
+- La conjonction des 3 représente le comportement d'un programme séquentiel.
+- Nous cherchons un compromis pour maximiser l'interactivité du produit
+
+
+--
+
+## État de l'art
+
+### Un (très) rapide résumé
+
+- Inventaire des différentes solutions existantes.
+  - Peu de littérature.
+  - Pas de taxonomie consensuelle, travail de classification 
+
+- Peu de réflexions sur les potentiels fautes byzantines induites par la (les ?) cohérences faibles.
+
+---
+
+# La suite
+
+--
+
+## La liste des tâches
+
+- [ ] Réaliser l'état de l'art
+  - [x] Gestion de la cohérence dans les systèmes répartis.
+  - [ ] Faire l'inventaire des solutions existantes. (BFT weak consistency).
+    - [x] Lister les solutions algorithmiques dans la littérature.
+    - [ ] S'intéresser aux solutions open-source (e.g.: etherpad)
+    - [ ] Classer les solutions.
+- [ ] Produire/adapter un algorithme dans une situation de référence (à déterminer).
+    - [ ] Formaliser les besoins du produit.
+    - [ ] Essayer de les satisfaire.
+- [ ] Réaliser un PoC.
+
+
+--
+
+## Pour les mois à venir
+
+Je vous propose une réunion en distanciel (~2h) pour :
+1. Vous présenter l'état de l'art.
+2. Placer le produit suivant ces contraintes.
+

+

+/**
+
+  [ sunblind ]
+
+  A blindingly sunny theme for Reveal.js with Lora + Leto fonts and a colorful border.
+  By Josh Dzielak, https://dzello.com/, License MIT
+
+  The bold border is optional and requires some HTML. To use it:
+
+  1. Add 4 divs to your HTML page:
+    <div class="line top"></div>
+    <div class="line bottom"></div>
+    <div class="line left"></div>
+    <div class="line right"></div>
+
+  2. Set { margin: 0.2 } in the Reveal.js initializer to make sure
+  your presentation content doesn't collide with the frame.
+
+  Like the theme but don't like the colors? Don't fret. Just change
+  $borderColor and/or $linkColor below to something else and rebuild.
+
+  Or if you don't want to rebuild the theme just override the .line background
+  property with some CSS:
+
+  .line {
+    background: <new-color>;
+  }
