Ah, I _knew_ I saw this exact site posted just a few days ago, but searching HN showed nothing recent. The fact that it was flag-killed explains why it didn't show up in the search.
I simply had deja vu when I saw this post (again) today, and wondered where I saw it. Searching HN showed nothing, which surprised me because I was certain I saw it here. The parent's link to the flag-killed post gave me an answer.
It is also technically a duplicate (https://news.ycombinator.com/item?id=8577800) but we'll give you the benefit of the doubt on that.
