Code sprint

• Start: Monday September 4th at 10:00 am

• Finish: Friday September 8th afternoon

• All days:

  • 10:00 Begin

  • 12:00 - 13:00: Lunch (in-house Mensa)

  • 15:00 - 15:30: Tee, coffee, and cake

  • 17:00 - 18:00 Status report

  • 19:00: Code sprint dinner at Trattoria Gianni & Giulia.

The primary focus of the code sprint will be on the following topics:

1. GAP - HPC-GAP integration
   • see the the HPC-GAP TODO wiki page for specifics
2. Towards GAP 4.9
   • work on a release check list (see this issue)
   • fix open issues, merged PRs, …
   • prepare a list of major/minor changes since GAP 4.8
   • if possible, prepare the actual release

Some ideas for secondary topics (may or may not be worked on):

1. Data structures in GAP (providing stacks, queues, hash sets, hash maps, …; see also https://github.com/gap-packages/datastructures)
2. MatrixObj (continue work from the previous GAP Days)
3. Documentation, Tutorials, Accessibility (talk about how to improve them, and ideally also actually do that)
4. Website (we probably need to a completely new one; can we hire somebody to do it? what is needed? etc.)
5. GAP - Julia integration (continue work from Oscar GAP Kickoff Coding Sprint (restricted access))

If you have any suggestions for the code sprint, please let the organisers know or create an issue on GitHub using the label “gapdays2017-fall”.

Please also look at the Wiki for details. Feel free to add pages there relevant to the workshop or code sprint.
