It was downvoted because you originally posted it to the wrong thread (https://news.ycombinator.com/item?id=29981188, instead of https://news.ycombinator.com/item?id=29985871). I've moved it to the right thread now.

Can you please review the site guidelines and stick to them in the future? You broke more than one of them badly here.
