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.
It doesn't look that way - it's not mentioned in the blog post neither on Pinterest's Github page.
Therefore, I don't really understand the purpose of this blog entry. Yay, they built something. What's the use, if it's not published and usable for others, too?
This is a wonderful example of false advertising...
He's talking about very general "code reading" on the whole article and then, at the bottom, he lines out which languages he knows - and it suddenly gets disappointing for anyone outside the Ruby/JS world.
He has to be more clear about that in the headline.
