Computer programmers of all expertise levels rely heavily on external support from other developers, web forums, or AI technologies while programming.  However, many help-seeking practices can be inefficient: other developers may not be available on-demand to support frequent questions; web forums do not always provide personalized support or quick responses to queries, and AI technologies cannot well assist with logical reasoning, and their answers do not often extend to less popular information needs.  My research explores how we can make it easier for people to get personalized programming assistance by coordinating and scaling the collective effort of experts, non-experts, and machines.  In this talk, I will overview three projects: 1) on demand expert assistance to improve developers productivity, 2) peer assistance to improve the programming learning experience, and 3) AI-powered assistance to help novices easily create programs.
