This is what differentiates the comp sci & (some) engineering crowd from anyone else. If you ask anyone a question on here, everyone will jump in to help you out and it's like this in real life too. Throughout my degree I noticed how eager my fellow classmates would be to help others solve difficult questions, problems etc and generally be nice.
Compared to business or even some engineering classes it was pure cut-throat. So, it's always refreshing to see stories like this, restores my faith in humanity.
