This did not fix the Tutor itself becoming overwhelmed however, which meant that students that depended on the Tutor were sometimes unable to use it.
This of course happened more during periods where the Tutor was being used a lot, such as evaluations and exams.
One can imagine that the experience for students who are already quite stressed out about the exam they are taking when the Tutor suddenly failed was not very good.
In the meantime, we had started to experiment with running Python code client-side in the browser (see section\nbsp{}[[Papyros]] for more info).
In the meantime, we had started to experiment with running Python code client-side in the browser (see section\nbsp{}[[#sec:papyros]] for more info).
Because these experiments were successful, we migrated the Python Tutor from its own server to being run by students in their own browser using Pyodide.
This means that the only student that can be impacted by the Python Tutor failing for a testcase is the student themselves (and because the Tutor is being run on a device that is under a far less heavy load, the Python Tutor fails much less often).

We also get notified when there are long-running requests, since we consider our users having to wait a long time to see the page they requested a bug in itself.
These notifications were an important driver to optimize some pages or to make certain operations asynchronous.

Usability was further improved by adding the =FriendlyTraceback= library.
=FriendlyTraceback= is a Python library that changes error messages in Python to be clearer to beginners, by explicitly answering questions such as where and why an error occurred.

Every time execution is handed off to student code (or even teacher code), appropriate error handlers and output redirections are installed.
This prevents the student and teacher code from e.g. writing to standard output (and thus messing up the JSON expected by Dodona).
