Authorities had for years complained that Skype’s encryption and other features made tracking drug lords, pedophiles and terrorists more difficult. Jihadis recommended the service on online forums. Police listening to traditional wiretaps occasionally would hear wary suspects say to one another, “Hey, let’s talk on Skype.”
Those who said “Hey, let’s talk on Gtalk.” in phone, also should be careful.
Since the performance of Great LAN is so frustrating, I have to use some new approaches to evade censorship.
Although with ssh I can circumvent most of the censorship, the DPI equipment interferes my ssh connection all the day. This is terribly annoying.
Rather than reconnect ssh without cease, I finally deployed an obfuscated ssh and enjoying it now.

闻说sy同学最近搞SVM和模式分类。看来人类对预测未来的研究总是孜孜不倦的,即使在混沌理论提出来之后。
初看SVM,有点像线性规划。再看了看SVM的paper, 现在搞SVM都用到最大似然估计、模糊数学、神经网络等算法了。用在股票预测上的也不少,相信应该比什么“画线八法”、“K线详解之 三阳开泰 浪子回头 风卷残云...”、“框图”之类的要准确。以前还想过对恒生、上证指数做傅里叶分析、方差分析的,看来有点too simple, sometimes naive了。
对于可微函数的话,预测短期的变化是有可能的,简单的办法如用泰勒展开都可以(这里假定函数收敛。现实的函数一般也都收敛)。对于连续但不可微的函数,那就很困难了。实际上,生活中的函数(至少表面上来看)都符合Weierstrass的结论:“大部分函数都是处处连续但处处不可微的”。
所以,我只能祝sy同学好运了。
上年申请的StartSSL证书快要过期了,需要renew。
StartSSL证书的续期步骤和新申请证书的步骤差不多。
1、导入之前注册时得到的p12证书,然后登陆到Control Panel:
Validations Wizard -> Type: Domain Name validation -> Enter Domain Name -> Select Verification Email -> 输入Email收到的Verification code -> finish;
2、Certificates Wizard -> Certificate Target: Web Server SSL/TLS Certificate -> 输入密码或跳过 -> 保存好key -> 选择需要部署SSL的域名 -> 等待审核;
3、(收到Email审核成功的通知后) Tool Box -> Retrieve Certificate -> 选择刚申请的域名, Continue -> 保存好Certificate.
至此,得到新的SSL证书。过期时间是2013-05-10,如下图。
