David Flanagan, author of the JavaScript: The Definitive Guide book, writes about JavaScript, Java, and book piracy.
HN links it for his posts on book piracy and what changed in new editions of his JavaScript book; one commenter notes the site was once hacked.
David has written about what's new, if anyone's interested: https://davidflanagan.com/2020/05/03/changes-in-the-seventh-edition.html
I also (briefly) interviewed him about it here: https://superhighway.dev/david-flanagan-interview
Ironically his blog(http://www.davidflanagan.com) says right now:
"My site was hacked and was hosting malware. So its down until I can rebuild it."
Straight from the author, what's new in the 5th edition:
