摘要: JUnit
JUnit是由 Erich Gamma 和 Kent Beck 编写的一个回归测试框架（regression testing framework）。Junit测试是程序员测试，即所谓白盒测试，因为程序员知道被测试的软件如何（How）完成功能和完成什么样（What）的功能。Junit是一套框架，继承TestCase类，就可以用Junit进行自动测试了。

摘要: Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin?
For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories?
In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories

摘要: 当今互联网的发展，已不是大鱼吃小鱼的时代，而是快鱼吃慢鱼的时代。互联网产品的制胜原则就是一个字——“快”。在各种形态的产品研发中，我们始终贯彻如一的价值观之一就是“快”，我们应该如何来理解和诠释“快”？又会从哪些方面来执行贯彻这个原则呢？

摘要: 软件测试的十二个误区大体总结如下：
1) 测试人员不需要了解软件开发的知识：
这个很要命的，我们谈到软件测试人员未来的发展方向大致有：自动化测试，性能测试，测试管理，项目经理。这其中自动化测试和性能测试包括项目管理，都会要求对软件开发有深入的理解，如何能设计一个好的自动化框架，好的性能测试用例，如何管理一个开发团队，这都需要我们在软件开发方面有所掌握。不单要掌握，而且要精通。此其一。
其二：如果不了解开发知识，测试人员很容易被开发人员牵着鼻子走，因为开发人员随便一忽悠，你如果不了解个中奥妙，你一个字也说不上来。(以前我们讨论 Cookie和Session，由于GoAhead不支持Session，只能用Cookie来控制，差点别开发人员忽悠了)

摘要: 写在前面：写Android程序有一个很重要的原则，不阻塞UI线程。因此Android提供了5种方法来，让一些耗时的作业在其它线程中执行，然后把结果返回给UI线程，以免阻塞UI线程。

摘要: android的selector的用法：
首先android的selector是在drawable/xxx.xml中配置的。
先看一下listview中的状态：
把下面的XML文件保存成你自己命名的.xml文件（比如list_item_bg.xml），在系统使用时根据ListView中的列表项的状态来使用相应的背景图片。drawable/list_item_bg.xml

摘要: The Monkey is a command-line tool that that you can run on any emulator instance or on a device. It sends a pseudo-random stream of user events into the system, which acts as a stress test on the application software you are developing.
The Monkey includes a number of options, but they break down into four primary categories:
Basic configuration options, such as setting the number of events to attempt.
Operational constraints, such as restricting the test to a single packag

摘要: Programmers can configure logging either by creating loggers, handlers, and formatters explicitly in a main module with the configuration methods listed above (using Python code), or by creating a logging config file. The following code is an example of configuring a very simple logger, a console handler, and a simple formatter in a Python module:

摘要: The list below defines some of the basic terminology of the Android platform.
.apk file
Android application package file. Each Android application is compiled and packaged in a single file that includes all of the application's code (.dex files), resources, assets, and manifest file. The application package file can have any name but must use the .apk extension. For example: myExampleAppname.apk. For convenience, an application package file is often referred to as an ".apk".

摘要: 一、ASE(Android Scripting Environment)为Android系统带来了脚本语言的技术，通过它我们可以编辑和执行脚本，和脚本解释交互。脚本可以访问多数Android API,目前有一个开源项目叫做Scripting Layer for Android (SL4A) ，提供了对python,javaScript, Lua等脚本的支持。ASE主要通过两种方式来访问 Android API,一种是通过JSON-RPC来访问,另外一种通过BeanShell（Java语言的动态版本）直接访问Android API。SL4AL架构如下图：

http://www.pythonchallenge.com/ 提供了不同level的Python题目，非常有趣的题目。做完一题后，把URL中的pc改为pcc可以看到上一题的答案
2)
http://projecteuler.net/ 里面有200多道题目，不要要求提交代码，只要最终答案，提供用各种语言来解决问题。这里（

非常好玩，有兴趣的朋友，快来试试吧
看看 project euler 的第一道题：
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
用 python 语言写出来是：
print sum(i for i in xrange(1, 1000) if i % 3 == 0 or i % 5 == 0)
This is the first edition of what is expected to become a recurring series on InfoQ. The idea behind this minibook is that a number of InfoQ articles and interviews which deal with a particular topic (in this case, REpresentational State Transfer, or REST) are combined together to provide a detailed exploration suitable for both beginners and advanced practitioners.

摘要: The Bloom filter, conceived by Burton Howard Bloom in 1970, is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set.False positivesare possible, but false negatives are not. Elements can be added to the set, but not removed (though this can be addressed with a counting filter). The more elements that are added to the set, the larger the probability of false positives

摘要: These posts have garnered a number of interesting comments. I want to address two of the negative ones in this post. Both are of the same general opinion that I am abandoning testers and that Google is not a nice place to ply this trade. I am puzzled by these comments because nothing could be further from the truth. One such negative comment I can take as a one-off but two smart people (hey they are reading this blog, right?) having this impression requires a rebuttal. Here are the comments:

摘要: One of the key ways Google achieves good results with fewer testers than many companies is that we rarely attempt to ship a large set of features at once. In fact, the exact opposite is often the goal: build the core of a product and release it the moment it is useful to as large a crowd as feasible, then get their feedback and iterate. This is what we did with Gmail, a product that kept its beta tag for four years. That tag was our warning to users that it was still being perfected. We removed
