SECURE COMPUTER-IMPLEMENTED EXECUTION AND EVALUATION OF PROGRAMMING ASSIGNMENTS FOR ON DEMAND COURSES

摘要

In one general aspect, a computer-implemented method can include receiving, by a computer system, code for a custom grader application, creating, by the computer system, a base custom grader container including the code for the custom grader application, associating the base custom grader container with an online course included in a repository included in the computer system, evaluating, by the computer system, the base custom grader container by executing the custom grader application in the base custom grader container, determining that the custom grader application violates a predetermined criterion, modifying the base custom grader container to prevent the executing of the custom grader application from violating the predetermined criterion, and storing, in the repository and in association with the online course, the modified base custom grader container including the custom grader application as a custom grader container image.
