I will travel to NewYork. What Can I do as a Programmer?

I'd suggest writing horror.

"My coming to New York had been a mistake; for whereas I had looked for poignant wonder and inspiration ... I had found instead only a sense of horror and oppression which threatened to master, paralyze, and annihilate me" - HP Lovecraft

Seems like he had a positive experience from a similar venture.

Interesting, are these "big N" companies that open to just knock on their door and request office tour? :)

I have no idea about it

Go to Facebook New York Branch, and tell the door guard I sent you, I already hooked you up with the human resource guy.... good luck my friend!

hahaha !

What do you want to achieve?

how new york programmers are different ? maybe

and their lives
