Why Hacker News recommends it

HN commenters point to it as a short, charming first-hand account of Unix history from someone who was there.

My favourite BWK video is about grep. [this video] The last part is very quotable: "They had one grave disadvantage, none of them were Ken Thompson"

Slightly off-topic, but Brian Kernighan has a great video about the origins of grep. If you know anything similar for awk, I'd enjoy watching it! [this video]

From the video [1]: "The UNIX text editor was called 'eee-dee' - it's not pronounced 'ed', at least by those in the know - it's pronounced 'eee-dee'. This was written by Ken Thompson, and I think it was basically a stripped down version of an editor called QED" [1] [this video]
