Programming for Pervasive Computing Environments Pervasive computing provides an attractive vision for the future of computing. Computing power will be available everywhere. Mobile and stationary devices will dynamically connect and coordinate to seamlessly help people accomplish their tasks. However, for this vision to become a reality, programmers must build applications that constantly adapt to an environment in which people, devices, and services keep coming and going. In my talk, I will explore how to make the programmers' task feasible. I will discuss how to structure necessary systems support and how programming for highly dynamic computing environments impacts application development. I will introduce one.world, a system that I have built, and reflect on my own and other's experiences with it, which demonstrate the practicality of building and deploying pervasive applications.
