It looks like at least some of the guides are licensed Creative Commons BY-SA.

For code samples do they do something similar to Mozilla?

Mozilla MDN:

“Code samples and snippets

Code samples added on or after August 20, 2010 are in the public domain (CC0). No licensing notice is necessary, but if you need one, you can use: "Any copyright is dedicated to the Public Domain. http://creativecommons.org/publicdomain/zero/1.0/".”
