CTK-Hackfest-Nov-2011

Event pictures

Hacking is hard work!

Introduction

Note: this page is a work in progress -- some information subject to change

Date: November 14-18, 2011

Location: INRIA - Sophia Antipolis, France

Goal: A follow on to the wildly successful previous hackfests!

Requirements: Attendees must be willing to spend their time during the event with writing ctk code that contributes to the main ctk roadmap. People who do not feel qualified for this are politely not invited :)

Group size: Maximum 20 participants so we can have a manageable working meeting. The organizing committee will invite and select participants based on input from TheTeam.

Site Hosts: Benoît Bleuzé

Future Events: Future hackfests will be announced in advance, and we hope lots of people will be interested in participating. The venue and activities at future hackfests will be determined based on the number of active participants in the project. We welcome participation via the CTK email lists, the source code repository, and this website.

Preparation

Developers should bring a laptop with the current CTK source code downloaded and built.

Use the CTK developers mailing list to discuss build issues and topics for ongoing work.

Phone conferences have been scheduled in the weeks leading to the event:

• Tuesday 25th October 2011 18:00 (CET) - 12:00 (EST)
• Tuesday 8th November 2011 18:00 (CET) - 12:00 (EST)

Topics and Projects

Roadmap development

• Develop a roadmap for the CTK core. It is advised to begin pondering on this in the weeks leading to the hack-fest in order to dedicate as much time as possible to the real hacking during the week. The roadmap for the CTK core is a good place to start your thinking. It has been written by Ivo and Marco at the start of the CTK initiative.

Travel & Hotel

Local contact

• If you have any troubles during your visit, call Benoit : +33 4 92 38 71 55 (or if not available, +33 6 32 78 59 92, but it's my mobile)

Airport

• Nice Airport: http://en.nice.aeroport.fr/

Transportation on Site The taxi is awfully expensive, count around 50 € to go from Nice Airport to Antibes.

The bus from Antibes to INRIA is the Express 100. It starts "Place De Gaulle", the closest stop to INRIA is "Templiers", costs 1€. From there it will only take you 3 minutes to reach INRIA: map from Les Templiers

Lodging Prefer Antibes to any other locations, Sophia-Antipolis is very badly connected to places to sustain you at night, and the buses stop after 20:00/20:30

• Rooms have been blocked for 11 people in the hotel l'Etoile:

http://www.hoteletoile.com/

phone number: +33 4 93 34 26 30 ‎

address: 2 Avenue Gambetta, 06600 Antibes, France

(54€ per night for a single room, 6.50€ for breakfast) Also here is a map with the hotel, and the departure of the bus line 100: File:Hotel etoile.pdf There are other addresses you might find attractive, but I have made no agreement with them:

• Hôtel Relais du Postillon (not far from the other, good reputation among the visitors of INRIA)

8 Rue Championnet, 06600 Antibes, France

http://www.relaisdupostillon.com/

+33 4 93 34 20 77 ‎

For the other hotels, Apparently you should avoid "Le Collier". Then I have no reports on how the other hotels in Antibes compares. But if you can't find a room in the above hotels, try others near the rail station or within the old town. This way you will get an easy access to the bus (the Express 100).

Meeting Location

• Inria Sophia Antipolis:

Catering
