Is there a self-hosted option for this? I think this would be an excellent resource for my students, but I'm having trouble getting my examples to run. (memory overload?)
Please email me examples that fail to run. It might be memory overload, or just other weird server crashes. (My alert dialog message isn't particularly informative.)
Online Python Tutor isn't meant for running large examples. Think of it as a "digital whiteboard"; I don't think anyone would expect to visualize a 100,000-step program with tons of pointers on a whiteboard :)
