There are many places where we could make use of Pathlib.

Look for any places that uses with open(...) and ask yourself:

• is the argument a string ?
• would it make sens to make it a Path(),
• how far upstream in the code can I make it a Path.

Don't try to bite more than you can chew (or more than I can review), try to fix 1 place at a time.

The notebook has its own internal idle-culling mechanisms, including shutting down idle kernels, shutting down itself when there's been no activity, and making decisions based on whether there are open connections or not. This is a lot more sophisticated, and offers much more granularity than the network-activity-based activity we have now.

For reference, we enable this config [on mybinder.org]
