奇怪，他们是怎么知道的呢？

apache的记录里面没有，机器肯定没有开finger之类的，反向出来的域名也应该是tsinghua之类的，domain是在yahoo买的，总不成是在交换机上监听HTTP Get吧？

有好多东西要看。

现在手里的有：

1. Randomized Algorithms by Rajeev Motwani and Prabhakar Raghavan 
2. Approximation Algorithms by Vijay V. Vazirani
3. Elliptic Curves and Their Applications to Cryptography, An introduction by Andreas Enge
4. Spectral Graph Theory by Fan R. K. Chung
5. Cryptography: Theory and Practice by Douglas R. Stinson
6. Algorithms on strings, trees and sequences by Dan Gusfield

需要买的书：

1. Modern Graph Theory by Bela Bollobas
2. Foundations of Cryptography: Basic Tools by Oded Goldreich
3. Introduction to Algorithms (Second Edition) by CLRS

其实还有好多经济方面的书要看，手里还有好多论文，不过先算了。
