摘要: JUnit
JUnit是由 Erich Gamma 和 Kent Beck 編寫的一個回歸測試框架（regression testing framework）。Junit測試是程序員測試，即所謂白盒測試，因為程序員知道被測試的軟件如何（How）完成功能和完成什么樣（What）的功能。Junit是一套框架，繼承TestCase類，就可以用Junit進行自動測試了。

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: 當今互聯網的發展，已不是大魚吃小魚的時代，而是快魚吃慢魚的時代。互聯網產品的制勝原則就是一個字——“快”。在各種形態的產品研發中，我們始終貫徹如一的價值觀之一就是“快”，我們應該如何來理解和詮釋“快”？又會從哪些方面來執行貫徹這個原則呢？

摘要: 軟件測試的十二個誤區大體總結如下：
1) 測試人員不需要了解軟件開發的知識：
這個很要命的，我們談到軟件測試人員未來的發展方向大致有：自動化測試，性能測試，測試管理，項目經理。這其中自動化測試和性能測試包括項目管理，都會要求對軟件開發有深入的理解，如何能設計一個好的自動化框架，好的性能測試用例，如何管理一個開發團隊，這都需要我們在軟件開發方面有所掌握。不單要掌握，而且要精通。此其一。
其二：如果不了解開發知識，測試人員很容易被開發人員牽著鼻子走，因為開發人員隨便一忽悠，你如果不了解個中奧妙，你一個字也說不上來。(以前我們討論 Cookie和Session，由于GoAhead不支持Session，只能用Cookie來控制，差點別開發人員忽悠了)

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中的狀態：
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），在系統使用時根據ListView中的列表項的狀態來使用相應的背景圖片。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)為Android系統帶來了腳本語言的技術，通過它我們可以編輯和執行腳本，和腳本解釋交互。腳本可以訪問多數Android API,目前有一個開源項目叫做Scripting Layer for Android (SL4A) ，提供了對python,javaScript, Lua等腳本的支持。ASE主要通過兩種方式來訪問 Android API,一種是通過JSON-RPC來訪問,另外一種通過BeanShell（Java語言的動態版本）直接訪問Android API。SL4AL架構如下圖：

http://www.pythonchallenge.com/ 提供了不同level的Python題目，非常有趣的題目。做完一題后，把URL中的pc改為pcc可以看到上一題的答案
2)
http://projecteuler.net/ 里面有200多道題目，不要要求提交代碼，只要最終答案，提供用各種語言來解決問題。這里（

非常好玩，有興趣的朋友，快來試試吧
看看 project euler 的第一道題：
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 語言寫出來是：
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

摘要: Android applications are, at least on the T-Mobile G1, limited to 16 MB of heap. It's both a lot of memory for a phone and yet very little for what some developers want to achieve. Even if you do not plan on using all of this memory, you should use as little as possible to let other applications run without getting them killed. The more applications Android can keep in memory, the faster it will be for the user to switch between his apps. As part of my job, I ran into memory leaks issues in Andr
