  •    afterwards: discussion; make a list of action items
    

• Tuesday

  • 10:00: Nicolas Thiery, Volker Braun, "Contributing to Sage"
  • 10:45: Max Horn, Olexandr Konovalov, Markus Pfeiffer, "Contributing to GAP" possibly with discussion of certain details
  • 14:00: Discussion: Detach GAP User/Lib Interface (This is on Tuesday to maybe give people some time to think on points raised during Volker's talk)
  • 15:00: GAP internals meeting (Max, Reimer, Steve, Chris, Markus, Olexandr, James, etc?)
  • 16:00: Julia/Transpiler/Interfacing with other software? (This is somewhat related to the previous topic)

• Wednesday

  • 10:00: Max, Olexandr, Sebastian: Join several release tools (and if people are interested in ReleaseTools, we can also give a brief demo how to use it to make a package release super-easy, at leasst for packages hosted on GitHub).
  • 11:30: Nicolas, Sebastian, Luca: Docker containers

• Thursday

  • 11:00-13:00, 16:00--open end: Max, Chris, Markus: hack on the datastructures package
  • 14:00: Olexandr, Chris, Markus, Max, Reimer, Steve: plan concrete steps for HPC-GAP merger
  • 16:00: All who are there: report on activities (possibly Friday morning, but Max is already gone)

• Friday

Topics we want to discuss

• Introduce webpage for GAP in the cloud
  • demo the Jupyter kernel
  • explain... (what is it, how does it work, ...)
  • ... future work..
• Improve the installation of GAP in SageMath and in SageMath cloud
  • make more (all) packages available
  • for the cloud: make GAP Jupyter kernel available
  • HPC-GAP
  • ...
• libGAP
  • What is it? An overview (Volker?)
  • What is its status
  • what needs to be done?
  • Integrate it with GAP repository (as a branch or even a compile time option...)
  • adapting libGAP to HPC-GAP ?! (e.g. being able to call from sage to HPC-GAP)
  • allow GAP code to call sage
  • ...
• Error / exception handling in GAP
  • important for language integration as well...
• GAP and Julia
  • GAP-to-julia transpiler ??
  • being able to call GAP code from Julia and vice-versa
  • why? what potential advantages?
  • what would it have to satisfy to be useful... ?
• HPC-GAP
  • continue from last week...
  • unifying HPC-GAP and "classic" GAP (goal of a single branch)
  • Adapting GAPDoc to HPC-GAP
  • Testing and adapting packages for HPC-GAP (e.g. the "forms")
  • ...
• General GAP stuff
  • Modularising GAP parser/reader/UI
• Sage
  • Improve group support in Sage (wrapped around GAP)
  • Add/improve semigroup support in Sage (wrapped around GAP)
  • ... maybe this can be done in a more generic way, which doesn't need manual work for every single GAP function to be wrapped..
  • Goal: write a small prototype this week, as basis for further discussion and work
• applications of GAP, Sage etc. to actual research :-)
  • e.g. semigroup representation theory...
  • implement some algorithms...
• wrap up some of the work and topics from the coding sprint
  • finish work on GAP Coding Style conventions
  • move live GAP website to use new repository
  • make datastructures package release
  • commit mailing list
  • ...
• Welcome to new contributors to our systems
  • How to make your first contribution to GAP
  • How to make your first contribution to SageMath
• Teaching material
  • setup repository for Software carpentry lessons on SageMath
  • improve Software carpentry lessons on GAP
• Google Summer of Code ??
  • SageMath will apply again this year, and GAP can join
  • please add project ideas and mentors on Sage's GSOC 2016 page
• Docker containers

Talks and tutorials

• Markus Pfeiffer: "GAP in the cloud" (11)
• Volker Braun: "libGAP" (16)
• XYZ: "How to contribute to GAP?" (3)
• Nicolas/Volker: "How to contribute to Sage?" (6)

Outcomes

• GAP in the cloud

• Install JupyterHub as an authentication frontend on the Azure machine
• Create a mechanism to start a pthread for replying to asynchronous events in GAP
• Distribute the Jupyter Kernel with the main GAP distribution?
