DEV 14 and HotMobile 15

The Fifth ACM Symposium on Computing for Development (DEV-5) focused on applications, technologies, architectures, and protocols for computing in developing regions. It highlighted research results from contexts where conventional computing solutions are often inappropriate due to limited resources and a variety of contextual factors. Focusing on innovative technical solutions to diverse contextual, infrastructural, and user challenges, the DEV-5 conference fostered exchange between computer scientists, engineers, and others interested in the use of information and communication technologies (ICTs) for development. The second report covers the ACM HotMobile 2015 workshop. HotMobile focused on mobile applications, systems, and environments, particularly for new directions or nontraditional approaches in mobile computing.
