It's not misleading, it's just an older meaning of the word "hacker" and one that still exists in the name of this site. Hacker's delight is a spiritual successor to the HAKMEM memo from the 70s. Guy Steele even wrote the foreword.

The term hacker has a long and storied history. A hacker is someone who makes hacks. A hack is a thing, typically a piece of code, which must be appreciated for its aesthetic beauty, regardless of whether it's particularly useful. [This term was obviously originally used sarcastically]. People strove to become hackers. It was a badge of honor.

In the 1980s the term "hacker" was possibly conflated with "cracker" by stupids in the media, and came to mean a software pirate or kid who broke into the Pentagon. But the proper meaning still hasn't been lost with the graybeards among us.

Reminded me of Smokers Delight by Nightmares on Wax: https://www.last.fm/music/Nightmares%20on%20Wax/Smokers%20De...

I hear all of you about how it's not misleading, but I must admit that when I clicked on this link I was expecting a different kind of book.
