Ideas for 'Hacking' topics:


Here are a set of questions that can help you prepare your talk :

  • In what context are you using OTB, what part of OTB and what for ?
  • What other software do you use along with OTB ? Do they have to interact with each others ?
  • What is working and what is not ?
  • What performances do you get (time, quality) ?
  • What is missing ?
  • Did you achieve everything you planned to ?

Guidelines for participants

  • Bring your laptop if possible, with a working installation of OTB (we will distribute a VM with everything as a last resort option),
  • Be prepared: questions, feedback, requests, problems you can not solve, pieces of code that do not work as you wish ...
  • Update the pad with your participation details (it helps us planning lunches and breaks)

Guidelines for all speakers

  • Lets make the talks short. Each topic should be presented in 15 min. at most.
  • The language for the event will most probably be French (if everybody speaks French in the room), however slides and materials should be in English if possible, to ease publication
  • We will try to do some video recording for further publishing online. If you do not wish to be recorded, please let us know
