参与评论思念总在分手后 [叶佳修]
作词：叶佳修 作曲：叶佳修
想要潇洒地挥一挥衣袖
却拂不去长夜怔忡的影子
遂于风中划满了你的名字
思念总在分手后开始
想要将你的身影缠绵入诗
诗句却成酸苦的酒汁
还由不得你想浅尝即止
因为思念总在分手后开始

阅读全文…这种情况下你会改变你的选择吗? (有意思的概率问题)
有三间屋子，A、B、C，一件礼物a，这件礼物被放到了三间屋子中的一个，现在让你来猜礼物在哪间屋子里。

问，剩下两间屋子中，X和另一间屋子Z中有礼物的概率如何？
答案并不是显而易见的……

As mentioned before, I will finally get the whole delphij.net out from beastie.frontfree.net because I will be finally graduated from the university and hence I must give maintainership (at least the principal maintainership) to someone who still live in the campaus so they can better solve problems encounted with. Well, I missed the post so much, as I have acted as principal maintainer and security officer there for more than three years: I became the security officer in 2000 when I joined the Association of Computer Machinery at School of Computer Science, Beijing University of Technology because nobody else in my grade can operate a Linux box :-)

阅读全文…How will a distributed peer system control itself?
This is a complex problem. A peer to peer system consists many self-determinating nodes is hard to control, and when it goes crazy, it will be easy to launch a distributed denial-of-service (DDoS) attack.
Here are some of my thoughts, well, they are not mature and some of them might be misleading, but I will write them here.
