[其他书籍] Python项目开发实战 第2版
本书来自真正的开发现场，是BePROUD公司众多极客在真实项目中的经验总结和智慧结晶。作者从Python的环境搭建开始讲起，介绍了Web应用的开发方法、项目管理及审查、测试与高效部署、服务器调试等内容，尽可能网罗了Python项目开发流程中的方方面面，有助于开发者建立有序生产环境，提高开发效率，让编程事半功倍。此外，在本书中Python仅仅是一个载体，很多知识点在非Python下也适用。
This book is from the real development site, is the experience summary and wisdom crystallization of beproud's many geeks in real projects. Starting from the construction of Python environment, the author introduces the development method, project management and review, testing and efficient deployment, server debugging and other contents of web application. It covers all aspects of Python project development process as far as possible, which helps developers to establish an orderly production environment, improve development efficiency, and make programming get twice the result with half the effort. In addition, Python is just a carrier in this book, and many knowledge points are also applicable to non python. (2020-12-14, Python, 14005KB, 下载2次)

因子分析是指研究从变量群中提取共性因子的统计技术。最早由英国心理学家C.E.斯皮尔曼提出。他发现学生的各科成绩之间存在着一定的相关性，一科成绩好的学生，往往其他各科成绩也比较好，从而推想是否存在某些潜在的共性因子，或称某些一般智力条件影响着学生的学习成绩。因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设
Factor analysis refers to statistical techniques that study the extraction of commonalities from variable populations. (2018-03-19, matlab, 239KB, 下载5次)

[其他书籍] 蒋介石传
与我们这个时代的其他军人政治家一样，蒋介石是个无所畏惧的人，允论是在心理上还是精神上都是这样。但他只是一个战术大师而非战略家。他的真正天才是善于搞政治阴谋。
蒋介石对希特勒纳粹及法西斯主义发生了极大兴趣，于是派次子蒋纬国赴德国深造，受希特勒两次召见，并组建一个法西斯机构“蓝衣社”…
蒋介石长得两眼炯炯有神，他经常剃着光头，蓄着短须，带有一股军人的风度。
但是，他的神情却不可思议——这并非因为他不擅言辞，而是因为他总是挂着一脸谦恭的微笑
