JupyterHub programming environment with student Notebooks

Secondary schools may want to consider JupyterHub to integrate coding with dynamic interactive graphing — A New Way to Think About Programming — allowing students to integrate science experiment results and program output within their own blog-like "Jupyter Notebooks."

• Jupyter Notebooks are widely used in the scientific community:
  • Intitutional FAQ: https://jupyterhub.readthedocs.io/en/stable/getting-started/institutional-faq.html
  • Getting Started: https://jupyterhub.readthedocs.io/en/stable/getting-started/
• Students create their own accounts on first use — e.g. at http://box.lan/jupyterhub — just as if they're logging in regularly (unfortunately the login screen doesn't make that clear, but the teacher does not need to be involved!)
  • A student can then sign in with their username and password, to gain access to their files (Jupyter Notebooks).
  • The teacher should modify and protect JupyterHub's overall Admin password, just in case: http://FAQ.IIAB.IO#What_are_the_default_passwords.3F
• Individual student folders are created in /var/lib/private/ on the Internet-in-a-Box (IIAB) server:
  • A student will only be able to see their own work — they do not have privileges outside of their own folder.
  • Students may upload Jupyter Notebooks to the IIAB server, and download the current state of their work via a normal browser.

Known Issues:

• 2021-08-07: The page that allows you to reset/change your own password is not accessible. Likewise Admin users cannot reset/change the password of any individual user at this time.
  • If necessary, a Linux administrator can delete the /passwords.dbm.db file at the very top of your Linux filesystem, allowing all JupyterHub users to (re)create new passwords. This does work, but is very heavy-handed (#2016).
• 2021-08-07: Teachers (i.e. Admin users) cannot currently access the very helpful "administrator's page" discussed at JupyterHub FAQ >> "How do I manage users?" and roles/jupyterhub/templates/jupyterhub_config.py#L1049-L1054 >> "Admin users have extra privileges".
