Android Debug Bridge | Android Developers
Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or higher.
adb 可以让电脑通过usb 连接 android 手机进行调试Debug，在满足上述条件下，必须进入手机设置选中USB DEBUG。
Apache Tika - Apache Tika
发现和抽取文档元数据、文本内容，文件编码，字符集工具
The Apache Tika™ toolkit detects and extracts metadata and structured text content from various documents using existing parser libraries. You can find the latest release on the download page. See the Getting Started guide for instructions on how to start using Tika.
CharsetDetector (ICU4J 51.1)
字符集分析发现，文件编码发现
CharsetDetector provides a facility for detecting the charset or encoding of character data in an unknown format. The input data can either be from an input stream or an array of bytes. The result of the detection operation is a list of possibly matching charsets, or, for simple use, you can just ask for a Java Reader that will will work over the input data.
Character set detection is at best an imprecise operation. The detection process will attempt to identify the charset that best matches the characteristics of the byte data, but the process is partly statistical in nature, and the results can not be guaranteed to always be correct.
For best accuracy in charset detection, the input data should be primarily in a single language, and a minimum of a few hundred bytes worth of plain text in the language are needed. The detection process will attempt to ignore html or xml style markup that could otherwise obscure the content.

MapReduce 编程模型在日志分析方面的应用
日志分析往往是商业智能的基础，而日益增长的日志信息条目使得大规模数据处理平台的出现成为必然。MapReduce 处理数据的有效性为日志分析提供了可靠的后盾。
本文将以对访问网页用户的日志进行分析，进而挖掘出用户兴趣点这一完整流程为例，详细解释 MapReduce 模型的对应实现，涵盖在 MapReduce 编程中对于特殊问题的处理技巧，比如机器学习算法、排序算法、索引机制、连接机制等。文章分三部分展开：首先介绍 MapReduce 编程模型，对其原理、对任务处理流程以及适用情况进行介绍；接下来描述了日志分析的例子 - 用户兴趣点挖掘的处理流程；最后对处理流程的几个模块分别进行了 MapReduce 的实现。本文的目的在于通过 MapReduce 在日志分析领域的具体实现，使读者对 MapReduce 对实际问题的处理有较为形象的认识。
