In this month's BayCHI meeting, two wildly different time periods collide. In the first half of the program Professor Daniel Rosenberg will focus on the emergence of the timeline as a common graphic tool. Rosenberg examines the origins of measured, linear representations of history, their alternatives, and their implications for historical thinking, as well as the power of graphic devices in the representation of information more generally.
Erik is the co-founder of Ushahidi (which means "testimony" in Swahili), a web application created to map the reported incidents of violence happening during the post-election crisis in Kenya. Currently, he is working with a team of mostly-African programmers to continue development of this new free and open source platform that makes it easier to crowdsource crisis information and visualize data.
