Safari 4, not so fast

Safari 4的beta发布，拿来用了一下，感觉是-相当快，特别是load java很快，渲染上面的速度感觉也比较明显。Java script方面拿chrome的2.0.164版本，用apple推荐的sunspider. 结果如下： 快的那个是Chrome的V8引擎，apple吹牛了。 机器是T61 3Gmem running windows 7 beta.

至于微软的ie8 beta (ship with windows 7 beta)就比较伤心了， 不过safari也“只快了”6倍多点，没有官方牛皮上的30倍那么多。

支持血汗工厂的黑名单

Lenovo、Microsoft、Dell、HP和IBM

2012年前请不要购买任何它们生产销售的(硬件)产品。

上次是香港大学生作了调查揭露出广东血汗工厂的丑闻。现在是美国劳工委员会更加详尽的调查(63页文件配图)指证血汗工厂的存在。虽然常常能在中文媒体上听到这些报道，我这一次还是为中国政府和广东地方政府感到羞耻，并且为作为一个中国人而感到羞耻。一个号称工人执政的国家却要由“特别行政区”的学生，要由美国这个最大的资本主义国家的工会来指控存在这种践踏人权的行为，来号召大家对相关企业进行抵制并施以压力。要么是这个国家已经完全没有保护自己人民的能力了，抑或是这个国家就是为了压榨本国人民而存在的。
