    I find it wonderful that the first mention of the constant on HN was in a username rather than in the title of a post.

      The first mention on the entire site appears to actually be in this comment from 7 years ago. https://news.ycombinator.com/item?id=203676 https://news.ycombinator.com/item?id=203676

  Thank lord this was actually a meaningfull explanation. The "magic constant" meme gave me always a headache. Kudos!
