Blog Action Day: Five apps to help save the world
TUAW is participating in this year's Blog Action Day on 10/15, an annual event in which bloggers around the world aim to spark discussion and awareness of serious and important issues. This year's topic is climate change, and fortunately, just like last year, we in the Apple community are in a pretty good place -- the company makes it a point to stay as green as possible, they have Al Gore on their board, and they make it safe and easy to dispose of their products in an environmentally friendly way. But there's always more we can do, from person to person -- making the earth a better place to live is going to take all of us working together. And so, here's five iPhone and iPod touch apps you can use to find out what you can do to take action on climate change. Some are paid, some are free, but all of them will give you fun and useful ways to help find approaches to dealing with climate change in your own behavior and life.
Researchers tout 20 million processor-strong supercomputer to study climate change
It looks like a group of researchers at UC Berkeley have come up with a rather unique way of solving the problem of getting supercomputers past the processing power / energy consumption barrier, with them now touting the possibility of using millions of low-power embedded microprocessors instead of conventional server processors. That tantalizing prospect has apparently already lead to a deal with Tensilica Inc, which will provide the Berkeley researchers with some of its Xtensa LX extensible processor cores to use as the "basic building blocks in a massively parallel system design." Ultimately, the researchers say they could one day build a massive supercomputer consisting of 20 million embedded microprocessors at a cost of $75 million, which they say would have a power consumption of less than 4 megawatts and a peak performance of 200 petaflops. That, they say, would be enough for it to create climate models at 1-kilometer scale or, as the researchers put it, more than 1,000 times more powerful than anything available today.[Via TG Daily]
