A Conversation with Mary Lou Jepsen - ACM Queue
[Notes and quotes here by Caren Litherland]

“If you look at what’s been happening in computers for the past 40 years, it’s been about more power, more megahertz, more MIPS. As a result, we’ve had huge applications and operating systems. Instead, at OLPC we focused on an entirely different kind of solution space. We focused on low power consumption, no hard drive, no moving parts, built-in networking, and sunlight-readable screens.” Interesting, prescient; focus on lower-power solutions preceded/anticipated larger cultural shift to mobile? /

“Right now I’m staring at my laptop. Not a single pixel on my screen is moving. What’s the CPU doing on? What’s the motherboard doing on? The way to get to low power—the big secret—is to turn stuff off that you’re not using. But nobody has ever made a laptop with a screen that self-refreshes.” /

“We wanted to design something that would engage kids beyond these rote-learning exercises, so the software architecture is completely different from a regular laptop. The user interface, called SUGAR, is based on the idea of everything being shareable; it explicitly enables collaboration.” /

“They want the screen—they want the screen desperately.” /

“The required contrast ratio for a display is now about 2,000 to 1, and the human visual system can’t see more than 500 to 1. It’s nuts.” /

“I started to look at what has been happening in specsmanship and *the perception of what quality is*, rather than how the human visual system perceives quality.” [my emph] /

“It would be a really good thing if you could lose yourself in a laptop and start to find another world.”

"Every manufacturer...claimed that using recyclable & non-toxic materials would add $30 to cost...Faced with these challenges, the OLPC team wound up designing the most environmentally-friendly laptop ever, almost by accident."

OLPC One Laptop Per Child Easy to Repair and Recycle – Greener Electronics and Computers -
"How simple is it? In Nigeria a 5-year-old girl with a can-do spirit took it upon herself to troubleshoot and repair the OLPCs of her classmates, said Jepsen. A teacher encouraged her, and the class set up a "Laptop Hospital," where the kids learn to repair their own hardware.

How is this green? Shipping is greatly reduced if people can fix their own gadgets on site. Jepsen pointed out that communities in Peru that now have OLPCs take 20 days to reach via roads from major cities. Instead of tossing whole products that have one or two problems, people can swap out individual pieces, leading to much less resource use."
