CTK-Hackfest-Dec-2012

Event pictures

Images from the hackfest

Introduction

Date: December 10-14, 2012

Location: | Hotel i Portici in Via Indipendenza , Bologna, Italy, Sala Montagnola (Room)

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

Requirements: Attendees must be willing to spend their time during the event writing ctk code that contributes to the main ctk roadmap. This means spending the week immersed in C++, Qt, DCMTK, CMake, and related technologies. People who do not feel qualified for this task 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: Alessandro Chiarini, Daniele Giunchi

Organizing Committee: Ivo Wolf, Stephen Aylward, Steve Pieper

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.
