Here's a great tip (though it will be obvious for some people).When you hack a computer in the game, you have four tries to hack it successfully. If you don't hack it successfully on the fourth attempt (as in, you don't guess the proper password), the station you're trying to hack will permanently shut down. But if you only try three times and bail out of the process before trying for a fourth time, the password will reset, giving you three more options. You can do this indefinitely without risking shutting the terminal down.
