This is a hard question. In my opinion it isn't a good idea to set out `to be a hacker' or `to do hacking'. Instead, learn things, explore and do interesting things, find out new and creative ways of doing things and you'll be close to the spirit of the thing. `Hacking' just means `creative playfulness'. Instead of `how to be a hacker' it might produce better search results if you looked for `how to be a Bash hacker', for instance. Or look for in-depth information on a specific tool. It is an ongoing misconception, originally coming from uninformed journalism, that `hacking' means `security breaking'. Those who do the latter are usually called `crackers'. As far as technical books, I have to recommend `The C Programming Language' by Kernighan and Ritchie (`K&R'). Richard Stevens has written good textbooks on TCP/IP. My preferred C book is `C Programming' by K. N. King (Norton 2008). There are a lot of good textbooks out there but many are intended for classroom use (so maybe not what you're looking for?). Hacking isn't just a matter of knowing a programming language. There's a mindset which I think is shown in the following books. Some have a historical bent but I found them all informative and hope you'll find some worthwhile. New editions may have come out - please do not assume these publication dates are canonical! Many of these you can probably find in a public library. I'm not saying to give money to Amazon. (You arguably shouldn't use Amazon, though. See: https://stallman.org/amazon.html) * Hackers by Steven Levy (published by O'Reilly, 2010), which someone already recommended. * Crypto by Steven Levy (Viking 2001) tells the story of the first so- called Crypto Wars. (One might argue that they never really ended.) * The Hacker Crackdown by Bruce Sterling (Bantam 1992), for more history about the `hackers' of the 1990s. Not always the kind of hackers you meant but also contains information about the earliest years of the EFF (eff.org). * The Cuckoo's Egg by Cliff Stoll (Pocket Books 1990) describes Stoll's pursuit of a cracker in the latter days of ancient UNIX. * The Art of Deception by Kevin Mitnick (Wiley 2002) because it's often easier to crack people than computers, but the investigative mindset is much the same. That last is getting off-topic but it brings me to some gratis things you might find interesting. Off the Wall with Emmanuel Goldstein from 2600 Magazine is a radio show that covers events from `a hacker perspective'. They are still around and have been for a long time. It can be found at: https://www.2600.com/offthehook/ There are many videos of talks and presentations at media.ccc.de. The CCC itself is an old hacker organization. As far as relevant Web sites, the essays on gnu.org are a good place to start, in my opinion. Somebody is thinking it, so I'll mention that rms might take issue with describing written works as `content': https://www.gnu.org/philosophy/words-to-avoid.html#Content Eric Raymond's site is http://www.catb.org/~esr/ but Raymond and rms don't always see eye-to-eye. However there is good history such as the Jargon File (www.catb.org/jargon/) and I do think what Raymond has written deserves to be considered. https://stallman.org is rms's site, which has various essays and his daily political notes. I hope you find something worth looking into in my long message. Errors and biases are of course mine. I'm not sure what's with some of the other replies. A grey hoodie is fine too and goes with a grey hat.
