Yup, it's great but that previous thread spent 20 hours on HN's front page just a couple months ago, which makes this one a dupe (see https://news.ycombinator.com/newsfaq.html).

Actually we put the current post in the second-chance pool (https://news.ycombinator.com/pool, explained at https://news.ycombinator.com/item?id=26998308) — we try not to do that for dupes but sometimes we do anyhow. Sorry—it was just a good HN post!
