I think those "tricks" are a little simple and probably don't deserve to be on the front page of HN, but they're not targeted at "someone dedicated to gaining access to your machine". They're targeted at reducing your profile to someone trolling google for vulnerabilities, which is not a bad idea.

I already do pretty much what the post says, plus other things like using generic and unguessable directory names for admin apps.
