Scene 47 of 189 · ≈ 1 min on screen
Mark Zuckerberg wants status and belonging Harvard's final clubs won't give him, so he builds a website that gives the world both — and loses his best friend and co-founder to the company he built to prove he mattered.
Mark at the campus bar: brilliant, status-obsessed, unable to read the room he's sitting in.
Before the Ad Board, Mark defends Facemash as exposing security flaws rather than apologizing, deflecting Cox's claim that they caught him in four hours.
Eduardo waits in the corridor and learns Mark got six months' academic probation.
Mark blames himself for the farm-animals blog post and Eduardo needles him about alienating every girl on campus.

MARK is in his Operating Systems class. This is considered the hardest class at Harvard and MARK is one of the 50 students with their laptops open as the professor takes them through an impossibly difficult lesson.

Okay, let’s look at a sample problem:
Suppose we’re given a computer with a 16-

A GIRL scribbles something on a piece of paper. Then hands it to the student next to her and nods that it should be passed over to MARK. While that’s happening--
PROFESSOR (CONT’D)
The system uses one-level page tables,
that start at address 0x0400. Maybe you

who knows? The first few pages are
reserved for hardware flags, etc.
MARK opens the note. It reads “U dick”.
He looks over and sees a couple of GIRLS looking at him with contempt.
PROFESSOR (CONT’D)
Assume page table entries have eight
status bits.
MARK closes his laptop, gets up and starts to head out of the hall.
PROFESSOR (CONT’D)
The eight status bits would be--
(re: MARK)
And I see we have our first surrender.
PROFESSOR (CONT’D)
Don’t worry, Mr. Zuckerberg, brighter men
than you have tried and failed at this
class.
MARK
(calling back)
1 valid bit, 1 modify bit, 1 reference
bit and 5 permission bits.
PROFESSOR
That is correct. Does everybody see how
he got there?
MARK walks out of the lecture hall and we
