Talk of Olivier Girardot (École Centrale de Nantes, Alumni 2009) and Eric Bachard (lead of the OpenOffice.org Education Project) at the Libre Software Meeting 2009 (http://2009.rmll.info/)

During academical year 2008-09, a group of students from Centrale Nantes worked on the integration of annotation features in the slideshow module of OpenOffice.org. Two of them (Olivier Girardot and Frédéric Gélot) have become official OOo developers and interact with the other members of OOo team (like Thorsten Behrens).

This talk synthesizes their work and their collaboration with the OOo Education project, that Eric Bachard presents in more details.

  • École Centrale Nantes & OpenOffice.org Education Project featuring: « The Eraser » Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • The project ● OOo and the Education Project ● Our project itself ● How it works ? ● The results of the project ● The future for OOo ● Conclusion 2 Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • OOo and Educoo ... Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • The OpenOffice.org Project, is ... A Community Project, Itself organized in (a lot of) projects Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Types of Projects There are 3 project types in OpenOffice.org organization ● Accepted : code development (API, modules), Marketing, QA,... ● Incubator : new experimental projects: Education, Extensions ● Native lang : native lang communities Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Role of the « Incubators » projects ● Experiment ● Validate a new need ● Innovate and make the OpenOffice.org Project progress Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Education Project is anincubator and INTERNATIONAL project type Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • The goals of the Education Project ? This is a young project, Belonging to OpenOffice.org with the main goal to create a bridge between Educational World and OpenOffice.org Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • ' Who ' is the Education Project ? Approximatively 100 members, Students, developers (mostly) From all countries All participate to OpenOffice.org Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • The 3 main objectives of the Education Project : ● Create a network of teachers using OpenOffice.org ● Provide a space for exchanging pedagogical contents, under free file formats ● Teach, provide young (core-)developers to write code for OpenOffice.org Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Back to the 3 Objective : rd provide new developers Idea : Associate : theory (The teachers) The know how (professional developers) The actors (students, profs, and so on) Mentors (OpenOffice.org Project developers) The needs (features for OpenOffice.org) Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Already started actions ● Online Courses « ClassRooms » ● Projects with engineers schools students, and shools contributions Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • ClassRooms Online Courses ( IRC ) See: http://wiki.services.openoffice.org/wiki/Education_Project/Class Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Education Project Effort ● Mentored projects with active participation of the schools http://wiki.services.openoffice.org/wiki/Education_Project/Effo Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Schools who joined the project Epitech/Epita (Paris, France) École Centrale Nantes (Nantes, France UTBM (Sévenans, France) Seneca College (Toronto Canada) … Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Examples Mozilla 1.7.5 → Seamonkey 1.1.14 migration (Pierre Pasteau / Epitech Paris ) QA in progress, will be integrated Developers who contributed : Frank Schönheit (Sun MicroSystems), Eric Bachard (unaffiliated) Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Examples Aude Quintana, Olivier Girardot (École Centrale Nantes): implementation of the eraser features, with Tablet PC and Impress. Code review in progress. Developers who contributed : Thorsten Behrens (Novell) Managed by Morgan Magnin, for Ecole Centrale Nantes Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Examples Frédéric Gelot, Pierre-Jean Parot (École Centrale Nantes): annotations implementation with Tablet PC and Impress Developers who contributed : Thorsten Behrens (Novell) Managed by Morgan Magnin, for ECN Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009

  • (partial) Conclusions The creation of reliable relations with engineers schools from everywhere works well (promising !) This project only needs help .. We miss - developpers - sponsors - … mainly money in fact (founding travel, hardware) Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • back to the feature ... Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Tablet Pc and Centrale ● The ECN was selected to take part into the HP contest : Technology For Teaching ● We chose to set up an OpenSource platform (Linux/Ubuntu) on these computers and improve the way it worked Improve how someone can annotate slides in OOo Impress during a slideshow Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • 2 projects in one : ● « The Eraser » : – To erase these annotations. ● « The Saving Machine » : – To save them and restore them. Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Objectives and Specifications ● Be able to completely erase screen annotations; ● Erase some parts manually at the following sizes: – Little – Medium – Big Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • OpenOffice.org ● C++ core; ● 8.36 Go of data once everything compiled ; ● 9,000,000 lines code ; ● Has it's own system of : – extensions : UNO (Universal Network Object) : to be able to contribute in Java/Python... Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • How things work Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Implementation and Concept ● First part : Persistence and Full Erasing Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Erasing Implementation ● Erase, means : – For one pixel, redraw it at its original color before the annotation; – For a slide, redraw it entirely; ● Problem : – Erasing requires to have a copy of the original image before to proceed the modification; Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Where is the bitmap ? Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Implementation and Concept ● Second part : Partial deleting Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Notion of Clipping ● Allows to define the part of the bitmap to be redrawn, means : – Partial erasing ; – Optimisation ; – Eraser size management; ● Add parameters to the User Interface for modifying the eraser size. Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • The bug with transformation Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Resolution ● With Thorsten Behrens's help, regarding the right coordinates transformation to perform Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Manage conflicts between projects ● The Saving Machine aims to assume annotation persistence ... ● … while The Eraser has the objective of erasing annotations; Means : conflicts to solve Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Maintainability guaranteed ● CWS creation (Child WorkSpace) ● Strong collaboration, code review and validation by Eric Bachard and Thorsten Behrens ● Follow-up of the OOo specification process Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Possible Optimisations ● Draw the polygons in a separate layer ; ● Improve the interaction between storage and erasing ; Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Conclusion ● Collaboration with a big scaled FOSS Project – Understanding of the existing code ; – Insertion in the community ; – Precise specifications writing ; – Real answer to a real demand; Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
  • Conclusion ● Perspectives : – Upstream integration in a future release – Possible improvements ; – Communication about the project ; Aude Quintana, Olivier Girardot & Eric Bachard Libre Software Meeting Nantes 9th July 2009
