Actually that book is paywalled now. It's been somewhat of a controversy that people contributed to the book thinking it was a community resource but now it's unavailable.

wow. although the last time he updated the (singular) username and password was october. i think people could just ask around for it.

still, controversial indeed.

Weirdly, the book itself says:

> Q: May I print this book / use it for teaching? > A: Of course! That’s why the book is licensed under the Creative Commons license (CC BY-SA 4.0)

So it would be legal for anyone else to host this.

I found a few versions which are hosted elsewhere:
