After another long hiatus due to work travel, I've started looking at content on Coursera and Udacity again. It seems like the breadth and depth of classes has expanded significantly in the past year -- with a much stronger monetization push in the "modular credential" model. Are people actually paying? It would appear that recent valuation puts Udacity's value at $1BN... which factors in significant growth expectation based on a rumored run rate of around $25MM.
Meanwhile, I worked on a small command-line utility for browsing JSON files recently, after getting frustrated by large JSON files that have no line breaks (taking a peek by calling head is not at all useful!).
