- Whirlpool算法被列入了ISO标准。主要原因是因为其强大的安全度。第一点，Whirlpool使用了和AES加密标准相同的转化技术，只不过，AES使用的模函数为：f(x) = x^8 + x^4 + x^3 + x + 1, 即0x11B；而Whirlpool使用的是：f(x) = x^8 + x^4 + x^3 + x^2 + 1, 即0x11D。第二点，Whirlpool的输出是512位的。为了加快计算速度，Whirlpool使用的所有表格都已经时间计算好了。Whirlpool在历史上

- 在中小型电力行业系统中，曲线的要求比较严格，虽然网络上面各种曲线控件非常多，但是很多只能提供一段时间的曲线显示或者历史若干个点的显示。比如在一个普通的小型水电站系统中我们会牵涉到许多的点（可能甚至达到400到500多个），一般的电站运行人员或者管理者希望能够对这类点的历史运行状况进行还原（即能够将历史运行的各个点状况进行还原），曲线就是非常重要的一个环节了 -SMEs in the power industry system, the curve of more stringent requir

- PJSIP has been actively developed since 2003, but its history goes well beyond that. The author has been developing SIP stack since 1999 during RFC 2543 era, and after several experimentation with different approaches in the programming (the first st
SHUTUP.ZIP
- ShutUp lets you automate clean-up tasks before shutdown. It can clean out selected history lists, eject CDs, delete the files in your TEMP directory, and run the programs you specify before shutting down your computer. It also lets you schedul
ucos_vc
- ucos是一个非常优秀的嵌入式操作系统，但作者只提供了bc下测试与调试代码，非常难于调试与学习，特别是初学者。vc是windows下非常优秀的IDE,如果把ucos移植到vc下运行，将非常方便ucos的调试与学习，有利于于ucos的推广。此项目的目的是希望能够把ucos及其相关的文件系统ucfs，GUI界面ucgui，网络tcp/ip都移植过来，方便广大爱好者学习。版本历史：ucos_vc0.11 时间：20050409描述：继续移植了Genie shell for UCOS II，为下一步文件
