Monday, August 31, 2009 A well earned retirement for the SOAP Search API There’s a time for everything in life: a time for playing, learning & growing up; a time for maturing, working & performing, and a time for retiring, relaxing & handing the reigns over to the next generation. This is true for products too, and this is why, six months ago, we announced our Labs program for Google Code. This program provides clear distinction between graduate developer products where you’ll find mature products with transparent deprecation policies which you can count on for the long run, and labs developer products where you can explore our newest products and get started with them early. As we also said in that announcement, the time has come for the SOAP Search API to retire – the new generation is around, has graduated, and has largely taken over already as a better and more versatile solution for the vast majority of use cases. In the spirit of our depreca

随 着富裕的中国人日渐希望投资海外，外国企业也加大努力吸引潜在的中国投资者，其中发起“求爱”攻势最为猛烈的当属国外房地产开发商。 Associated Press 2012年10月8日，塞浦路斯阿依纳帕度假区附近，游客欣赏夕阳时的剪影。 近日的某个周六，来自20多个国家的约140个房地产开发商在北京举行的一个展会上展示了他们的楼盘。为了吸引潜在买家的目光，这些开发商分发了非 常精美的小册子，并用那些突出所售楼盘且配色夸张的照片装饰他们的展位。某些开发商甚至请来戴着兔子耳朵的年轻女销售员招揽客户。 但对很多参加展会的中国买家来说，最吸引他们的莫过于外国居留权所带来的诱惑。这也使得来自塞浦路斯的30位参展商成为整场展会最显眼的一个群体。 为 什么选择塞浦路斯？虽然温和的气候、丰富的历史和地处地中海东部这一不错的地理位置可能令这一面积不大的岛国成为一个具有吸引力的居住地，但该国真正吸引 人的地方在于其为移民设置的门槛低到令人难以置信的程度：任何人只要花30万欧元（约合300万人民币）在该国购买一套房产就可以自动有资格享有欧盟永久 居留权。   参加展会的邵刚（音）说，和美国、加拿大等国相比，塞浦路斯的移民门槛相对较低，这一点非常吸引我们。邵刚说他在中国一家贸易企业工作，说话时他正在浏览塞浦路斯一位开发商发放的小册子。 此次展会吸引大批参展人群的还包括来自新加坡和澳大利亚的开发商。这两个国家均提供具有吸引力的投资移民项目。 傲丰置业集团(Affluent Investment Group)董事总经理Tony Du也在展会现场帮助一家澳大利亚开发商回答中国买家与移民有关的问题。他说，和我谈话的100个人中，有60%想要移民，只有40%是单纯想在海外置业的。 Lingling Wei

WSDL stands for "Web Services Description Language". Although designed to be flexible enough to describe many types of web services, it is most often used to describe SOAP web services. A WSDL file is just that: a file. More specifically, it's an XML file. It usually lives on the same server you use to access the SOAP web services it describes, although there's nothing special about it. Later in this chapter, we'll download the WSDL file for the Google API and use it locally. That doesn't mean we're calling Google locally; the WSDL file still describes the remote functions sitting on Google's server. A WSDL file contains a description of everything involved in calling a SOAP web service: • The service URL and namespace • The type of web service (probably function calls using SOAP, although as I mentioned, WSDL is flexible enough to describe a wide variety of web services) • The list of available functions • The arguments for each function • The data

search the names at ubuntu. 1. Installing PyXML The first library you need is PyXML, an advanced set of XML libraries that provide more functionality than the built−in XML libraries 2. Installing fpconst The second library you need is fpconst, a set of constants and functions for working with IEEE754 double−precision special values. This provides support for the special values Not−a−Number (NaN), Positive Infinity (Inf), and Negative Infinity (−Inf), which are part of the SOAP datatype specification. 3. Installing SOAPpy The third and final requirement is the SOAP library itself: SOAPpy.

Thank you note 基本上建议大家写. 除非你牛到不行或是公司也牛到不行,凭实力,那爱写不写无所谓. 为啥这样说呢? 因为有些小公司,或大公司但不是那么红的部门,有时候他们自己也不太 有自信,假设你不写他们说不定会觉得你不够看得起他们,会觉得留不住你. 另外,大家都是面好多round,假设有重复在几个round面到一样的人, (HM之类的),不写 就从头开始不写,写了最好要写到尾,前面不写后面写也无所谓, 最好是不要前面几 round写后面就发懒不写,这样也会让人误会你on site完兴致没了不积极之类的. 当然大多数写不写都无所谓,但注意这些东西,可以让你面试完心理好过一点,不会去后 悔早知道写啊之类的一些胡思乱想. however, 如果on-site完,有in

There are five important features of HTTP which you should support. 1. User−Agent The User−Agent is simply a way for a client to tell a server who it is when it requests a web page, a syndicated feed, or any sort of web service over HTTP. When the client requests a resource, it should always announce who it is, as specifically as possible. This allows the server−side administrator to get in touch with the client−side developer if anything is going fantastically wrong. 2. Redirects Sometimes resources move around. Web sites get reorganized, pages move to new addresses. Even web services can reorganize. A syndicated feed at http://example.com/index.xml might be moved to http://example.com/xml/atom.xml. Or an entire domain might move, as an organization expands and reorganizes; for instance, http://www.example.com/index.xml might be redirected to http://server−farm−1.example.com/index.xml. Every time you request any kind of resource from an HTTP server, the server includ

HTTP web services are programmatic ways of sending and receiving data from remote servers using the operations of HTTP directly. If you want to get data from the server, use a straight HTTP GET; if you want to send new data to the server, use HTTP POST. (Some more advanced HTTP web service APIs also define ways of modifying existing data and deleting data, using HTTP PUT and HTTP DELETE.) In other words, the "verbs" built into the HTTP protocol (GET, POST, PUT, and DELETE) map directly to application−level operations for receiving, sending, modifying, and deleting data. The main advantage of this approach is simplicity, and its simplicity has proven popular with a lot of different sites. Data −− usually XML data −− can be built and stored statically, or generated dynamically by a server−side script, and all major languages include an HTTP library for downloading it. Debugging is also easier, because you can load up the web service in any web browser and see the raw data. Mod

Unicode is a system to represent characters from all the world's different languages. When Python parses an XML document, all data is stored in memory as unicode. You'll get to all that in a minute, but first, some background. Historical note. Before unicode, there were separate character encoding systems for each language, each using the same numbers (0−255) to represent that language's characters. Some languages (like Russian) have multiple conflicting standards about how to represent the same characters; other languages (like Japanese) have so many characters that they require multiple−byte character sets. Exchanging documents between systems was difficult because there was no way for a computer to tell for certain which character encoding scheme the document author had used; the computer only saw numbers, and the numbers could mean different things. Then think about trying to store these documents in the same place (like in the same database table); you woul

>>> from xml.dom import minidom >>> minidom >>> minidom.Element >>> from xml.dom.minidom import Element >>> Element >>> minidom.Element >>> from xml import dom >>> dom >>> import xml >>> xml Here you're importing a module (minidom) from a nested package (xml.dom). The result is that minidom is imported into your namespace, and in order to reference classes within the minidom module (like Element), you need to preface them with the module name. Here you are importing a class (Element) from a module (minidom) from a nested package (xml.dom). The result is that Element is imported directly into your namespace. Note that this does not interfere with the previous import; the Element class can now be referenced in two ways (but it's all still the same class). Here you are importing the dom package (a nested package of xml) as a module in and of itself. Any level of a package can be treated as a

python的module import 只能导入模块，不能导入模块中的对象（类、函数、变量等）。如一个模块A（A.py）中有个函数getName，另一个模块不能通过import A.getName将getName导入到本模块，只能用import A。如果想只导入特定的类、函数、变量则用from A import getName即可。 import一个module时，会执行该module的所有方法，并且将该module添加到importing module的命名空间中。 A module's body executes immediately the first time the module is imported in a given run of a program... An import statement creates a new namespace containing all the attributes of the module.  如： fibo.py # Fibonacci numbers module def fib(n): # write Fibonacci series up to n a, b = 0, 1 while b < n: print b, a, b = b, a+b def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while b < n: result.append(b) a, b = b, a+b return result print "EOF" In [1]: import fibo EOF In [2]: import fibo In [3]: fibo. fibo.__builtins__ fibo.__doc__ fibo.__hash__ fibo.__package__ fibo.__setattr__ fibo.fib
