CTK-Hackfest-Nov-2013

Introduction

Date: Nov 4-8, 2013

Location:

Room 1.19 (Monday, Friday) and Room 2.14 (other days) Malet Place Engineering Building, University College London.

How to get here.

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: Matt Clarkson (m.clarkson@ucl.ac.uk), Miklos Espak (m.espak@ucl.ac.uk)

Organizing Committee: (need to ask people)

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:

• To be announced

Topics and Projects

XNAT Library

Interested people: Miklos, Nicolas, Florian, Ivo, Sascha

• Stabilize API and make it more robust
• Merge to master

Open topics

• Error handling (Miklos)
• Timeout handling (Miklos)
• Unit tests for ctkXnatCore
• Zip support (Sascha)
• Up/Download support in the API (Sascha / Miklos)
• SSL support (ask about disabling SSL) (Florian?)
• Support browsing files attached to assessments
• General API review (Sascha, Miklos, Ivo, Florian)
• Add API documentation

CLI Library

Florian, Sascha, Ernesto, Steve, Marco

Open Topics

• Add a CTK "test" for validating the XML of external CLIs
  • Maybe a "web service" for quickly validating the XML files
• CTK should become the official CTK schema hosting site
• Default values for some elements are problematic (e.g. for SpinBox)
  • Have a best practices document how to handle optional default values
• CLIs depending on external dependencies (shared libraries) are problematic
  • Probably nothing we can solve inside CTK
• The UiLoader should be more customizable (JC did that in a branch for the Slicer integration)
• Maybe have a way to check for long running modules during the XML retrieval and cancel them (more of a developer thing)
• Add a method for clearing the XML cache (probably in ctkCmdLineModuleManager)
• Having a new web services front-end could be interesting

Discussion

• Make GIMIAS CLI modules work with the ctkCmdLineModuleExplorer (Ernesto)
