按照他们的习惯,把别人的话直接省略几个关键词后开始抨击…反正你国内普通草根翻不了墙,我说怎么样就怎么样.人家发言是反对基于政治目的的审查,支持对于暴力等的审查,到丫嘴里就变成了反对审查,然后又说美国自己在公众图书馆禁止色情网站,我晶
这傻鸟还举了德国google限制色情网站的例子,人家希拉里明明说的是反对有政治动机的审查,丫傻傻地还举了这个例子.完了还说不能让美国人掌控互联网,这东西明明是人家自己搞的,然后说我有个东西你玩不玩,然后中国说,我玩,玩了没几天,发现这东西上面真玩意太多了,老百姓能自由发布自己的政治目的,不对劲阿,于是开始封锁,砸了无数金钱,发现还是封不住,然后大叫:我要改游戏规则…
能给你改游戏规则么,一边举例美国佬封索马里域名(我真不知道封过),自己至今一直在劫持facebook,twitter,youtube等知名网站的域名解析那就别说了,因为这些网站危害了国家安全,那各地运营商的dns域名解析一直都在植入广告该怎么说呢?晶!
附上人家讲话内容:美国国务院将向促进网络自由的草根运动提供资金；呼吁减少中东地区女性利用社交网站惹来杀身之祸的案例；美国政府将把互联网视为美国长期在海外推进“民主”的重要工具；互联网安全等。
另关于网络审查:我希望拒绝支持有政治动机的审查，能成为美国技术公司的招牌商标。它应当成为我们的国家品牌的一部分。

周末在家看hulu,3M的adsl非常流畅,得意ing,觉得我的vps真强,速度真不错,然后顺手netstat -an| grep ESTABLISHED一下,发现无数连接,正奇怪呢,突然想起来hulu貌似用了p2p,果然…
看来p2p也应该是视频网站上高清的出路,如果时延性能做好,视频会议也应该是p2p

迅雷是个啥?迅雷=小偷+强盗
小偷:
迅雷现在不管你是否允许上传,自己在后台遍历你的文件,然后发现有用的就给你忽忽满速往上传,经常发现公司网络上行太慢,一看,我靠,有个家伙上行10M,得,又一迅雷受害者
http://www.google.cn/search?client=safari&rls=en&q=迅雷+偷偷上传&ie=UTF-8&oe=UTF-8
强盗:
做网站的都知道,放迅雷盗链是第一要务,要是你不小心谁给你扔了个热门mp3上去,那就完了,迅雷偷偷给你搞来无数链接,不管你多少带宽都能给你吃掉,经常把你的web server吃满,让人崩溃,更可恶的是居然伪造referer,让你防不胜防
http://www.google.cn/search?client=safari&rls=en&q=迅雷+盗链&ie=UTF-8&oe=UTF-8
这种流氓软件居然还在广泛流传,看来还是这片神奇的土地会产生无数神奇的故事阿…

shopex使用方便，有客户端工具可以做数据操作，但是source是加密的
ecshop别的不说，是opensource的，统计功能相对完善
如何是好呢？
猛然间发现，原来ecshop已经被shopex收购了，faint！
彻底无语了，看看是否还有别的商城来打破他们的垄断。
