Fancy a PDF read on a new topic? Of course you do! Learning is essential to getting into a hacker mindset. How are you going to exploit a server’s vulnerabilities without knowing any Perl? Lucky for us, the team at HackNMod found some shady FTP site (with an HTML-based index) that features hundreds of scanned books in PDF form. You’ll find titles on hacking, programming and plenty of other subjects available for download. Get on it, though. Who knows how long this will stay up before O’Reilly or McGraw-Hill sends over a DMCA takedown notice.
Obviously, bookends are not required.
