很好的关于junit4与Mockito的文档，是英文的，目前没有看到国内有翻译的。

讲解单元测试的好处，注重实践，测试框架用的是TestNG。

这是外国深度学习大佬Adrian Rosebrock博士自己编写的python+opencv的一些教程，里面有许多有趣实用的opencv的学习案例，英语水平不好的阅读建议打开翻译软件一起阅读学习！！(如果有侵权请联系我删除)

Fundamentals of Statistical Signal Processing, Volume III,Practical Algorithm Development 第三卷，PDF完整版！！！

学习DX11的进阶书, <> 是最好的DX11参考书。

本书(是英文版！英文版！英文版！)是一本实用性非常强的电子元器件和实用电子电路的参考工具书，从电路基本原理的介绍开始，对各种类型的电子元器件进行了详细具体的分类介绍。介绍了各种电路的设计及实用电路；在数字电路中，介绍了寄存器、计数器等各种中规模集成数字器件，以及存储器、可编程逻辑器件等大规模集成电路，详细介绍了微控制器及模块化电子设备，并给出了相应的实际应用程序实例, 如Arduino工程示例；介绍了各种电机及控制电路；同时，还结合图解的方法，介绍了制作实用电子电路的过程、方法、调试步骤、安全组装和注意事项等。

Switch-Mode Power Supplies Spice Simulations and Practical Designs By Christophe P. Basso * Publisher: McGraw-Hill Professional * Number Of Pages: 889 * Publication Date: 2008-01-14 * ISBN-10 / ASIN: 0071508589 * ISBN-13 / EAN: 9780071508582 * Binding: Hardcover Product Description: Harness Powerful SPICE Simulation and Design Tools to Develop Cutting-Edge Switch-Mode Power Supplies Switch-Mode Power Supplies: SPICE Simulations and Practical Designs is a comprehensive resource on using SPICE as a power conversion design companion. This book uniquely bridges analysis and market reality to teach the development and marketing of state-of-the art switching converters. Invaluable to both the graduating student and the experienced design engineer, this guide explains how to derive founding equations of the most popular converters…design safe, reliable converters through numerous practical examples…and utilize SPICE simulations to virtually breadboard a converter on the PC before using the soldering iron. Filled with more than 600 illustrations, Switch-Mode Power Supplies: SPICE Simulations and Practical Designs enables you to: * Derive founding equations of popular converters * Understand and implement loop control via the book-exclusive small-signal models * Design safe, reliable converters through practical examples * Use SPICE simulations to virtually breadboard a converter on the PC * Access design spreadsheets and simulation templates on the accompanying CD-ROM, with numerous examples running on OrCADË, ICAPSË, µCapË, TINAË, and more Inside This Powerful SPICE Simulation and Design Resource • Introduction to Power Conversion • Small-Signal Modeling • Feedback and Control Loops • Basic Blocks and Generic Models • Simulation and Design of Nonisolated Converters • Simulation and Design of Isolated Converters-Front-End Rectification and Power Factor Correction • Simulation and Design of Isolated Converters-Th
