Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?
This is your opportunity to ask questions. No question too simple or too silly.

Do you have any interesting/unusual heuristics to share?
I'm sure this isn't original, but I think I derived it independently--the social status of pedestrians in the outdoors public is inverse to the amount of possessions they carry with them. Someone dragging a luggage is homeless while a backpack means low income. Highly contextual with lots of exceptions of course, but if you're walking/jogging on a trail in an affluent area, chances are people not carrying anything are less a threat than people lugging large bags and backpacks.
If you have a bachelor’s in computer science degree outside the US and a master’s (but no more) from an American university then you will be the worst programmer I talk to this week.
