HTTP State Management Mechanism
STATE AND SESSIONS
This document describes a way to create stateful sessions with HTTP requests and responses. Currently, HTTP servers respond to each client request without relating that request to previous or subsequent requests; the technique allows clients and servers that wish to exchange state information to place HTTP requests and responses within a larger context
今天在CNet上面看到一篇文章,分析出Google计划利用光纤组建一个全球的网络。好像并没有什么有力的证据来证明这一结论,唯一的理由就是Google在招收这方面的人才,而Google的发言人又拒绝对这一情况作出评论。
"Google is looking for Strategic Negotiator candidates with experience in...(i)dentification, selection, and negotiation of dark fiber contracts both in metropolitan areas and over long distances as part of development of a global backbone network," the posting reads, in part.
不过是很奇怪,Google这样一个企业,如果发展
复杂性的计量
算法的复杂性是算法运行所需要的计算机资源的量,需要的时间资源的量称作时间复杂性,需要的空间(即存储器)资源的量称作空间复杂性。这个量应该集中反映算法中所采用的方法的效率,而从运行该算法的实际计算机中抽象出来。换句话说,这个量应该是只依赖于算法要解的问题的规模、算法的输入和算法本身的函数。如果分别用N、I和A来表示算法要解问题的规模、算法的输入和算法本身,用C表示算法的复杂性,那么应该有:
C =F(N,I,A)
其中F(N,I,A)是N,I,A的一个确定的三元函数。如果把时间复杂性和空间复杂性分开,并分别用T和S来表示,那么应该有:
T =T(N,I,A) (2.1)
和 S =S(N,I,A) (2
Google涉及的范围真是越来越广了,Google Desktop、Gmail、GBrowser、Google Print,不过这些好像都还可以理解,不过今天居然看到硬件产品了,无语...
Honey, we shrunk the Google
By and large, big companies have gotten the word: offering good search is good for business. Customers are happier (and more likely to buy something) when they can quickly find the right information on a website. Employees are more productive when they actually find what they need on their networks. They don't have to reinvent
看了下面的blog,自己也试了一下,发现Google不太厚道...
Where O Where Have My Results Gone, Google?
When searching on Google, it's not uncommon that if you drill into the listings, Google will come back with the response "In order to show you the most relevant results, we have omitted some entries very similar..."
What happens is that in these cases, Google is only showing you the documents it thinks ar
