alt Hacker News> if you're not writing security-oriented software
It's hard to define what's security oriented and what is not. For example, is this HN web app security oriented? Not in the way of sshd but it must keep our accounts data separated and it must not let people exfiltrate data from the db, where for example it is storing the emails of some of us.
It depends on the time. Twenty or thirty years most software was not security-oriented. Nowadays, everything is online and therefore everything needs to be vigilant about security.
