C++ 6 from the ground up by Herbert Schildt

MF RC522是应用于13.56MHz非接触式通信中高集成度的读写卡芯片，是NXP公司针对“三表”应用推出的一款低电压、低成本、体积小的非接触式读写卡芯片，是智能仪表和便携式手持设备研发的较好选择。 MF RC522利用了先进的调制和解调概念，完全集成了在13.56MHz下所有类型的被动非接触式通信方式和协议。支持ISO14443A兼容应答器信号。数字部分处理ISO14443A帧和错误检测。此外，还支持快速CRYPTO1加密算法，用语验证MIFARE系列产品。MFRC522支持MIFARE系列更高速的非接触式通信，双向数据传输速率高达424kbit/s。 作为13.56MHz高集成度读写卡系列芯片家族的新成员，MF RC522与MF RC500和MF RC530有不少相似之处，同时也具备许多特点和差异。它与主机间通信采用连线较少的串行通信，且可根据不同的用户需求，选取SPI、IIC或串行UART模式之一，有利于减少连线，缩小PCB板体积，降低成本。 (asdfasdf asdf )

说明：  软件质量是被大多数程序员挂在嘴上而不是放在心上的东西！ 除了完全外行和真正的编程高手外，初读本书，你最先的感受将是惊慌：“哇！我以前捏造的C++/C程序怎么会有那么多的毛病？” 别难过，作者只不过比你早几年、多几次惊慌而已。 请花一两个小时认真阅读这本百页经书，你将会获益匪浅，这是前面N-1个读者的建议。(Software quality is the majority of programmers have paid lip service rather than the heart! In addition to being a complete layman and a real master of programming, your first reading of the book will be a panic: "Wow! How can I have so many problems with the C++/C program I've made up before?" Don't be sad, the author is only a few years and a few times earlier than you panic. Please spend one or two hours reading this 100 pages of Scripture carefully, and you will benefit a lot from it. This is a suggestion from the previous N-1 readers.)

在本文件中有很多的题目可以选择，可以成为一个实验的指导书，也可以成为自我完成目标的指导书。(many thymes can be chosen)

主要是基于mtlab的程序，包含特征值与特征向量的提取、训练样本以及最后的识别，小波包分析提取振动信号中的特征频率。( Mainly based on the mtlab procedures, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  使用ATL在VC中进行开发的实例,ATL是开发COM的类库，和MFC也可以共用(Using ATL in VC)

黑客破解一类的书籍，不仅能破解网站，也能破解软件，好好学吧(Hackers break a class of books, not only to crack sites, but also crack the software, a good school bar)

Linux下多线程编程指南，pdf格式，介绍了Solaris操作系统中POSIX线程和Solaris线程的多线程编程接口，该指南将指导程序员如何创建性新的多线程程序以及如何向现有的程序中添加多线程(Under the multi-threaded Linux Programming Guide, pdf format, introduced the Solaris operating system, POSIX threads and Solaris threads of the multi-threaded programming interface, the guide will guide programmers how to create multi-threaded nature of the new procedures and how to add to an existing program Multithreading)

关于队列的实现，按照算法导论书上得来，简单易用。(On the implementation of the queue, according to the book Introduction to Algorithms, come on, easy to use.)
