gron. Ingenious tool for working with JSON on the command line: run “gron URL/filepath” to transform a JSON document into a multi-line assignment structure designed to be easy to run grep against. Grep it, then pipe it back into “gron --ungron” to convert the filtered data back to JSON again. It solves a similar problem to jq—which is addressed in the README: “gron’s primary purpose is to make it easy to find the path to a value in a deeply nested JSON blob when you don’t already know the structure; much of jq’s power is unlocked only once you know that structure”. # 9:16 pm

Ask HN: What are the best MOOCs you’ve taken? Most useful Hacker News thread I’ve seen in a while: a torrent of great recommendations for online courses to learn everything from machine learning to astrophysics to songwriting. # 5:17 pm
