NeXus Code Camp - January 2020

The 2020 NeXus Code Camp is scheduled for 3 days in January 2020: Jan 21 (Tuesday) - 23 (Thursday). The code camp will take place at the Advanced Photon Source, Argonne National Laboratory, IL, USA (near Chicago).

(We used an online poll to help decide the exact dates.)


NeXus periodically convenes a Code Camp to develop NeXus software components through intense effort by small groups working on specific projects and tasks. It is expected that those attending the 2020 NeXus Code Camp will already have a strong foundation and understanding in aspects of the NeXus software and come ready with knowledge, tools, and ideas to make significant progress during the event.

Specific projects and tasks are described on the GitHub issue tracker. Issues for consideration at 2020 NeXus Code Camp will be added to the Code Camp’s Topics page (edit here). These issues will be prioritized on the first day for handling at the Code Camp.

(For more info on code camps, try searching Google for “code camp” or “codeathon”. Events such as the EPICS Codeathon would be reasonable templates for this NeXus code camp.)
