Maybe so, but those cultural aspects are utterly irrelevant for most jobs.

Some info on my job: I program for an HFT company. Right now, I'm taking a break from building some graphing addons to my companies trading system (waiting for the program to finish running). Once that's done, I'll return to my primary task of increasing P&L by losing less money when certain market events happen. Any hint as to my ethnicity yet, or do you need UML diagrams, latencies, etc to determine that?

Here is a project I'm working on (command line bug tracker interface, i.e. access trac/github without leaving the command line). Can you point out my cultural influences? http://github.com/stucchio/Idli

You can easily detect the cultural differences between programmers and business guys. With a bit more effort, you can detect the differences between a computational physics guy (me) and CS guys (my coworkers). I doubt you could detect the ethnic differences. Can you really say ethnicity matters if you can't detect the result of it?
