• Open HackMD and use it for questions and collaborative notes/guidance
• This talk is recorded, but with OBS, so that Zoom audio will not be recorded (unless I explicitely say it is). So, mainly use HackMD to communicate, but you can safely say things (I will repeat questions).
• Make a note in zulipchat when I show personal data so I can mask it later.

User interface

• Authentication, log in
• Spawner list
  • Connection to courses
  • Auto-generated based on username
  • Polls username (id, actually python's pwd.getpwnam)

Student

• uids/groups
• Filesystems
  • $HOME - temporary
  • /notebooks
  • nbgrader exchange directory - note permissions
  • /coursedata
  • Q: Can you copy the data from jupyter to Aalto Home easily?
    • You can always rsync to kosh, but that's not necessarily "easy"
    • You could probably smb mount the Aalto home?
      • nvm this would probably need root
  • Q: How long was the data persistend on jhnas?
• Default working directory
  • Default working directory of a shell
• Kernels
• umask
• Image
• Where is this configured:
  • jupyterhub_config pre_spawn_hook
  • the image

Instructor (nbgrader)

• uids/groups
• Overall, all the same as students
• Filesystems
• umask
• The nbgrader directories
  • /course
  • /coursedata
  • exchange directory

Course management

• What we need: uids, groups, access permissions, images
• Repo: jupyterhub-aalto-course-meta
• YAML file per course
• courses.py
• update.sh
• group management

Image

• repository
• inheritence system
• build system
• base setup (jupyter, etc)
• specific course software
• authentication
• hooks
• problems
• Q: why philosophy of 1-2 mega images instead of multiple smaller? Is mega really easier to maintain?

Backend

• relevant git repositories
  • jupyterhub-aalto
  • jupyterhub-aalto-secrets
