ASK HN: How to become security expert
cperciva: Start by reading code.  Then go read some security advisories.  Then go back and read some more code.Before you can do new work in computer security, you have to understand what's been done already... and the only good way to do that is by reading advisories and looking at the vulnerable code and how it got fixed until you say "oh, so THAT'S what a <insert vulnerability type here> looks like".
