A Conversation with Leo Chang of Clickshift To explore this month’s theme of component technologies, we brought together two engineers with lots of experience in the field to discuss some of the current trends and future direction in the world of software components. Queue Editorial board member Terry Coatta is the director of software development at GPS Industries. His expertise is in distributed component systems such as CORBA, EJB, and COM. He joins in the discussion with Leo Chang, the cofounder and CTO of ClickShift, an online campaign optimization and management company. Chang also cofounded a company called flyswat, which was purchased by NBCi, and served as the vice president of software development at Savi Technology. TERRY COATTA I want to start off by asking how you would define component.
