It reminds me of an incident involving an old colleague of mine at some kind of graduate recruitment fair thing. He walked past a stand which was trying to hire engineers which had some code on the wall when the following exchange happened:
Recruiter: Hey there! <indicates the code> Do you know what this is?
Colleague: Err, <looks…thinks for a bit>… It *looks* like some sort of network protocol
Recruiter: <smug> No, it’s *COMPUTER CODE*
I like to pause movies when some code is shown and see what it is. Apparently you can break into pentagon by knowing basic sql and high-level employees have alternate life writing tcp implementations and graphics libraries.
