Why is a random textbook so high up? And why is it on a website I've never heard of before (no starch)?

Why is it so high up? maybe because of Nostarch's reputation? And people's interest in stuff like that? https://en.wikipedia.org/wiki/No_Starch_Press

And you never heard of Nostarch Press before? So you are one of today's lucky ten thousands: https://xkcd.com/1053/

So what exactly does happen when you admit you don't know a thing? And what's worse: admitting you don't know a thing or showcasing you don't know a thing by presuming the wrong thing? Intriguing stuff.
