Does he ask the same, tired questions others ask (at a rate of once or more per minute)?
Does he clearly lack the ability or inclination to ask the almighty Google?
Does he refuse to take the time to ask coherent, specific questions?
Does he think helping him must be the high point of your day?
Does he get offensive, as if you need to prove to him why he should use Ruby on Rails?
Is he obviously just waiting for some poor, well-intentioned person to do all his thinking for him?
Can you tell he really isn’t interested in having his question answered, so much as getting someone else to do his…
