At first, mobile phones were limited, clunky, dumb luxuries. Now, almost half of the world’s population carries in their pockets or purses more computing power than was involved in the Apollo program that landed men on the moon—and safely brought every one of them home. But a smart phone is not just a computer. What are the implications of always carrying a computer that is also a two-way radio and a GPS location device? Does it make you safer, or put you at risk? How is the ubiquity of mobile technologies changing the world? What are the intersections between mobile technologies, crime, fraud, privacy, security, and encryption? What are the testing and quality implications of this modern, mobile world? Join Rex for some thoughts, case studies, and suggestions about the exciting and sometimes scary world mobile technologies are bringing to us.
