上学时,民间一直传说,选择题中选C的比例大一些。虽然当时没有找到科学依据来支持这一观点,大家对哪道题真的没辙的时候,基本上也就是选C了。
现在倒是可以用科技手段验证一下:比如,用百度或者谷歌分别搜索“这道题选A”、“这道题选B”、“这道题选C”、“这道题选D”,都会发现“这道题选C”的结果确实多不少。
重口味的技术工人可以用以下土方法快速验证(以百度为例):
$ for i in A B C D; do echo -n “选$i ” && wget “http://www.baidu.com/s?wd=“这道题选$i”” -O- 2>/dev/null|grep “找到相关网页约” |awk ‘{print substr($3, 32, 5)}’; done
选A 2,970
选B 1,470
选C 3,310
选D 924篇
瞻仰alexa全球500大牛网站名单的前二十个,有以下感想:
google及其家族很猛!
没想到microsoft.com也进榜单,都是谁整天去?
“用了都说好”的维基百科流量真大;
排名第八的百度旁边的介绍还是“Music search engine and free MP3 & video streaming for all kind of topic.”,该改一下了;
google排17名,人数不到一亿的德国这么喜欢搜索么;
中文的占四席,中国人很强大。

我的手机经常收到发票、担保之类的垃圾短信,接到“响一声就挂”的骚扰电话。最恶心的是,这帮烂人很多都是选择半夜三更行凶,让人痛苦不已。(鄙人由于工作敬业的原因,晚上不能关机,囧)
貌似也看到运营商对这个问题叫苦连天,他们虽然启用了各种高科技过滤系统,还是收效甚微,因为魔高一尺,道高一丈。从接收到的短信关键字的变化,好像可以 看出运营商也是很直观地使用了关键字过滤技术,比如,推销发票的垃圾短信从最初赤裸裸地使用“发票”二字,变成了“发飘”“发漂”之类。所以,如果只是按 照这样的思路来堵截的话,恐怕只能被人家牵着鼻子走。
能不能换个思路来与他们作战呢?骚扰短信的特点就是一个或者几个手机号在一个相对集中的时间,把内容相同的短信发送给很多的手机,那么,运营商的系统检测 到这样的发送行为时,自动提交给客服人工干预,确认是垃圾短信的话,就对该发送号码进行冻结。“响一声就挂”这种骚扰电话也可以用类似的手段,如果一个手 机号在集中的时间内拨打很多手机号都是一接通就挂掉,就可以考虑把它冻结了。
#可能这个思路也很幼稚,如有高人请指教。
其实更大的问题是,运营商可能并不是很愿意花心思来遏制垃圾短信、骚扰电话的问题,因为毕竟大量的垃圾短信,多多少少给运营商带来了收入。更何况,在某些运营商的地方分公司,“群发广告短信”本来就是他们的日常业务类型之一。
