I looked at your profile and saw this:

>a failure of a hacker who doesn't have the energy to do much of anything anymore

Failure of a hacker? Pardon my language, but I fucking doubt it. Prove me wrong and tell me why you're a failure, please.

I find myself falling into this ridiculous trap all the time. It's easy to do too... I mean, holy shit, I'm posting on hacker news, a place where multi-millionaires posting about their wildly successful startups is the norm.

I'll find myself thinking that I'm a failure because I don't work at facebook, and I'll probably never be rubbing shoulders with people at the googleplex. I mean...my god, what a total worthless waste of space I am that I'm not a member of the top %0.001 of programmers in the US? Because my office isn't in some uber-cool San Francisco loft? Because cisco isn't employing a team of engineers to try and build switches that can handle the amounts of traffic that my data-center crushing websites produce? Because I'm not routinely completely changing the game in application development?

That's ridiculous. I really really really highly doubt that you're a "failure of a hacker", the fact that you post here pretty much proves that you're not.

Likewise. In my experience with them, the interview questions are really specific and targeted, thus making it unlikely for everyone to know the precise answer. Unfortunately, they are indeed looking for an exact answer.

So just because we couldn't recite an exact response with compilable code doesn't mean we're dumb. We just aren't experts in that particular topic. Hang in there!
