/* You won't believe the one weird trick this function uses to compute inverse square root */A common example would be business logic code polluting the "View" of MVC.
code reviewer: "Why are you retrieving the sales tax jurisdiction from the database and computing sales tax in the gui form?"
programmer: "Well, the form has the TOTAL amount displayed to the customer so it made sense to me to put that db-dependent code there."
code reviewer: "No, that's what the "Model" code is for. That's the "M" in "MVC".
programmer: "Oh, the model source code is where I update the GUI progress bar because that's where the state variable that keeps track rows processed is stored. "
"Fork is rather simple, once you get the hang of it, but the memory management can be a bitch. See 'mm/memory.c': 'copy_page_range()'"
