It's also available from the publisher:

https://www.informit.com/store/awk-programming-language-9780138269722

You can get it on paper, or an ebook in watermarked pdf and epub formats
(which means it's not tied to Kindle). I had some difficulties with my
pre-order, but since it's been released that shouldn't be an issue.

He doesn't know how to use NNTP. Newbies, you know.

That had me scratching my head. You can't have an action without
enclosing braces. But it's still legal syntax because... it's an
expression serving as a pattern. The assignment itself is a side
effect.

Care needs to be taken when using this shortcut so the expression
doesn't evalute as false:

$ printf 'one 1\ntwo 2\nthree 3\n' | awk '$2=4'
one 4
two 4
three 4
$ printf 'one 1\ntwo 2\nthree 3\n' | awk '$2=0'
$

$ printf 'one 1\ntwo 2\nthree 3\n' | awk '$2="4"'
one 4
two 4
three 4
$ printf 'one 1\ntwo 2\nthree 3\n' | awk '$2=""'
$

I never bothered, because Perl does everything that Awk does, just as
concisely, and more besides.
