原题：
Design question: Say you have hacked in to a network and can deploy your bot thousands of machines, how would you design your bot so that all the machines work together to download a website, say wikipedia. There should be load balancing and a page should be queryable given its URL.
题目：如果你已经黑了几千台电脑，如何设计机制来用这些肉鸡来协同下载一个完整的网站，比如Wikipedia？要求能够提供查询机制，确定特定的网址被下载到了哪台特定的机器。
解法：这是设计题，肯定没法写出代码了。我只能凭自己能想到的地方，写了几句分析。

Different OS, different configuration. 4 You may choose one or more bot machines as scheduling server, and the rest of them as working server. 5 The query URLs will be tranformed into digital sign, so as to decide which bot will perform what downloads. 6 In case that some of the machines lost contact or broke down, others will make up for the loss. 7
