今天看了Yochai Benkler在TED的演讲“Open-source economics”，里面他提到2004年中期IBM蓝色基因超级计算机的性能刚刚超过了日本产的DEC”地球模拟器”超级计算机。但与此同时，另外”一台”超级计算机也在运行着—-“SETI@Home”，由全球450万个人电脑用户通过互联网贡献他们的空闲运算力而组成的超级计算机。而这台超级计算机的运算能力超出了IBM蓝色基因的三分之二之多。这有点像“集中力量办大事”的故事，但有些许的不同。人们没有像我们过去那样，贡献自己所有的精力，而只是把自己零碎的运算能力贡献出来，不影响自己的工作，就完成了更大的计算。
A month ago, on Aug 23, 2007, I left China from Beijing Internetional Airport. And since the difference of timezone, we arrived at Winnipeg on Aug 23, 2007 again. From that time to now, I’ve spent a whole month here.
I, with my parents, drove to Beijing on Aug 22. We lived in Beijing Guangxi Hotel. A friend of my father received us. In the afternoon, I washed myself and had a rest. At night, father’s friend invited us to a restaurant for supper. I tried Maotai there.
