北京大学ACM比赛题目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.

Data_Structures_and_Algorithms - These notes accompany Data Structures and Algorithms II. The course, to a large extent, follows on from Data Structures and Algorithms I. However, while DS&A I focused on fundamental datastructures, DS&A II will focus on practical algorithms, applicable to a wide range of tasks. The approach will be somewhat less formal, with a little more focus on applications.

Windows下DNS ID欺骗的原理与实现在DNS数据报头部的id（标识）是用来匹配响应和请求数据报的。现在，让我们来看看域名解析的整个过程。客户端首先以特定的标识向DNS服务器发送域名查询数据报，在DNS服务器查询之后以相同的ID号给客户端发送域名响应数据报。这时客户端会将收到的DNS响应数据报的ID和自己发送的查询数据报ID相比较，如果匹配则表明接收到的正是自己等待的数据报，如果不匹配则丢弃之。 假如我们能够伪装DNS服务器提前向客户端发送响应数据报，那么客户端的DNS缓存里域名所对应的IP就是我们自定义的IP了，同时客户端也就被带到了我们希望的网站。条件只有一个，那就是我们发送的ID匹配的DSN响应数据报在DNS服务器发送的响应数据报之前到达客户端。

DVD Demystified quickly became the bible of the industry. It has helped so many people understand DVD technology. In spite of the publication of the DVD bible in late 1997, DVD technology refused to stand still. Unfinished variations such as writable DVD and DVD-Audio became less unfinished, and new applications such as WebDVD and Divx reshaped markets and perceptions.
