I have built the almost same system ~1.5 years ago http://pags.cs.bilkent.edu.tr but It did not get any traction :/ Here is a screenshot: http://i.imgur.com/U3pjIJA.png and even featured on Docker blog https://blog.docker.com/2014/04/docker-in-education-intervie...

But nevertheless, happy to see some competition on the road :) Good luck.

Hey everyone my name is Prah and I'm one of the founders of Mimir. There is a huge demand for good engineers so we built Mimir to solve the problem at the source. Our platform automates most the bureaucratic work involved in teaching a CS course and allows instructors to focus on their students.

If anyone has any questions, I would be happy to answer them.

Professors don't even grade assignments in my experience.

It's the Graduate students.

The University of Waterloo uses Marmoset, and it works well: http://marmoset.cs.umd.edu/index.shtml

I can not understand how a university could commit itself to rely on such external (proprietary) tools... This kind of vendor-lock-in within the teaching process would bug me both as a teacher and as a student. I built something similar (https://github.com/moschlar/SAUCE), which is open source.
