weibullguy dropped us a link from the IEEE's site. They've voted the CTO of the One Laptop Per Child project as a 'Dream Job 2007'. Held by Mary Lou Jepsen, a former CTO for Intel, the position entails world travel, speaking with heads of state, and dealing endlessly with the technological challenges of a project designed to change the world. In the article, she relates some of the details of her first task on the job - redesigning the OLPC's display. "According to Jepsen, the display her team eventually marshaled into existence requires, depending on the mode, only between 2 percent and 14 percent of a typical laptop display's power consumption. ... To save watts, the display can switch between color with the backlight on, in low light, and black-and-white with the backlight off, in sunlight. OLPC's engineers trimmed battery usage further by, among other things, adding memory to the timing-controller chip, which decides how often a display refreshes. That trick enables the display to update itself continually without using the CPU if nothing changes on the screen."
