Great dinner at after some intense hacking


Date: July 9-13, 2012

Location: 1249 Boylston Street - Brigham and Women's Hospital, Boston, Massachusetts USA

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: Steve Pieper and Ron Kikinis

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.

  • Talk with Dominique (Debian packager) to understand what is missing See https://github.com/commontk/CTK/pull/158
    • Build from upstream PythonQt (to be done this week) Yes check.png Few patches still need to be contributed upstream. See documentation
    • Release a version of CTK (Work on policy this week and maybe release this week).

Transportation on Site

Google's public transit search works well in Boston. The site is about 5 blocks from subway stops and busses. Parking on-site is $10-$15 per day. Cabs are fairly convenient for most trips (perhaps $40 to/from the airport but $10-$15 for trips within town).


There are a lot of hotel options in Boston - several within easy walking distance of the 1249 Boylston facility and everything is accessible by public transport. Note that on Sunday night before the hackfest there is a big baseball game in the neighborhood (at Fenway Park) so hotels may be more expensive the first night, but should be cheaper the rest of the week.
