It's the start of the Summer, I'm in my 2nd year MS-CS. I began a simulation last night at 9PM that's still running (usually 14 hour turnaround). I just got in, sat at my desk and thought "I'm bored, guess I'll check HN" and THIS is what I see.
I've been authoring a post on solving interview questions in map/reduce between experimental runs myself, so I guess I already hit the "bored graduate student" point too...
I remember having to resist the urge to map/reduce everything in interview questions :P. Somehow, I don't think interviewers want to hear how you'd use a cannon to solve a tiny problem.
