It is time to turn around and walk the other way, unless you are entertained by stupid arguments.
Mac vs PC. Run the other way. I can get around in all of them. I swear less at Macs. I praise Microsoft for guaranteeing that I will continue to be employable till I die.
iPhone vs Android: Run the other way. I can get around in both. I swear at both of them equally for being moronic in different places.
Spaces vs Tabs: WTF? I don't worry about it... Sublime, textmate, etc do what they do. The only time I start crying is when Excel decides it cannot figure out quoted comma delimited content on text to column. (which I finally learned to paste, text to column, undo, undo, paste again and everything is fixed)...
Curly brace underneath function or to the right of the params parens? You can get me started on this in a meeting, but I will follow whatever the practice guidelines say for the company. I like to see the curly braces line up though.
Butter vs Margarine? Salted vs Unsalted? I prefer Butter. I prefer Unsalted.
