According to Newsday (and reported worldwide), IBM and folks at Los Alamos have just raised the bar on computing power, with a $13 million, 20,000 processor, supercomputer nicknamed "Roadrunner". The thing can perform 1 quadrillion calculations (floating point operations, for those who care) in a single second.From a sustainability standpoint, the bad news is that this single computer draws about about 4 megawatts of power -- more or less the same amount of energy as a modern railroad locomotive.

This week, I’m going to include the full letter from a reader, because I think it’s a great illustration of what many of us go through in our twenties (inside academia or out), searching for the right career fit, for validation, and for our own definition of success. This is what she wrote:

In the museum tower of the NRA headquarters, there's first a little store, and then a little theater with a film about the history and significance of guns in America. Vintage rifles line the walls of the theater, and American flags and eagles abound.

Kids are mean in elementary school. They are mean in college. When I first began teaching I befriended many students the way many theatre faculty do. Between rehearsals and classes and so much down-time in the green room, we can spend upwards of twenty-plus hours a week with any given student. I spent a lot of time engaging in ‘drama’. I heard them tell tales, tales about each other. I thought this pretty harmless until a few years later when I came to a period in my life where the student tales included commentary on my private life, particularly as my marriage was falling apart.

So, given my evolving understanding of issues of scale, have I lost sight of what Graham Cliff calls "the substance of sustainability"? I hope not. I don't think so.

From the 'Signs of Hope' department: apparently, the top-selling vehicles in America for the last fifteen years have been trucks. In May, they were the Toyota Corolla and the Honda Civic.

Okay.
