Can you please edit out personal swipes from your HN comments? You did it repeatedly, and the site guidelines ask you not to: https://news.ycombinator.com/newsguidelines.html.
It's great, of course, to provide correct information. But please do it without putdowns; you don't need them, and they acidify discussion.

Generally speaking, it's not against HN's rules to be wrong. How could it be? We're all wrong about nearly everything. But it is against HN's rules to post disrespectfully, put others down, etc. - for the obvious reason that it poisons community discussion, plus is unnecessary.
