Also, please don't post the same comment twice: https://news.ycombinator.com/item?id=21505062. Duplication is a sure way to add noise not signal. (Also, when there are duplicate submissions, we'll probably merge them, in which case your comment will appear twice in the same thread or we have to make special effort to exempt it from merging, and also move any replies that it got so that the replying users aren't punished for your duplication.)
