This is one of the reasons I love HN: a grapevine of important things to help developers fix their dev environments, security things we need to be aware of for our servers, new APIs to take advantage of, and other important stuff.
Well, if you use OS X, write against Node.JS, work at a SV startup and are interested in big data / machine learning. It is quite a bubble.
Isn't using the word "bubble" against official HN rules?
I live in a rural part of France, use OS X, Ruby/Elixir, I'm not working for any SV startup, and indeed what the OP describes in one of my favorite things in HN!
I use OS X, write Node.js, live in Northeast Iowa and I too find the information great, like OP said.
