Important things engineers fight about:
*On a scale of 0 to 4, is 0 "highest priority" or "lowest priority"?
*Should array indices and counter values begin at 0 or 1?
*Should reset signals be active low or active high?
*Should a signal that halts an operating process to load up new control information be called "load," or is it a type of "reset"?
*What is the best text editor program?
*When writing code, how many spaces wide should a tab character be?
*Where should you use CamelCase? What about ALL_CAPS and all_lowercase?
