Would STACK work under WAMP? If so, is it also under the same Maxima version restriction?
Thank you in advance.
Yes, it works. You do need to use a supported version of Maxima. Normally, support is kept fairly up-to-date with new Maxima releases, but there was a specific issue with the last release.
Got it. Thank you!
Thanks Tim,
Just to be specific, please avoid Maxima 5.37.0 or later until I have time to add support. Some functions in STACK do not currently work with the latest version.

Thank you for the clarification. I was able to successfully run the health script thanks to your replies.
I have an additional question. In your presentation on YouTube (
) I can see that the STACK's response is rather slow although you must be the only user on your localhost. In your book, you also mention that Maxima's response is the limiting factor.
Before I dive in, is it possible to have some idea on what kind of computing power I would need to host 10 simultaneous users using STACK quizzes?
I am wondering if it would be better for me to send a self-hosted (with LAMP+Maxima+moodle) Ubuntu virtual machines to students and transmit only their grades to online Moodle. That way, it will be near infinitely scalable.
The slow part is the time it takes to run Maxima to do the maths processing. There are some things you can do to speed it up a bit.

A good way to get an impression of how well your server will cope under high load is to run all the Answer test tests. You can find that on the admin screen, nearl the link to the healthcheck. Running those tests puts a very high load on the Maxima back-end (particularlly if you go to health-check and press the "clear the cache" button first.)
Thank you for the valuable information!
