web-based access and implements the well-known design strategy known as Model 2 (see Resources). The Rails version has optimized the integration between the Controller and the view (which minimizes the configuration file) and automatically makes the controller instance variables available to the view.
Project directory structure: All Rails applications have the same project structure, where directories are used to store application code, database configuration, public static files, and scripts
An important part of WEB design and developer work is cross-browser testing, who let us live in this happy and painful era, there are so many browsers in front of us, there is the nightmare of the total can not get rid of IE6. This article describes a variety of issues and knowledge related to Cross-browser testing, including rendering, platforms, devices, and JavaScript engines.

The Windows 7 Super taskbar locks various program startup files and IE9 Web pages, making our day-to-day operations easier, but presumably there are more people and small ones, hoping to lock more things into the taskbar, such as files, folders, and so on. However, Windows 7 does not support the direct targeting of these objects to the taskbar, it is necessary to make a detour to the indirect implementation, how much more inconvenient, until the small
analysis (on-site web analytics, or based on the site's own analysis), simply speaking, this site analysis is to measure the site of the user's access behavior, for example, which kind of user landing page (landing page) makes it easier for visitors to make a purchase, or what kind of source (such as a search engine or display AD) The visitor's access behavior on the site is different. In-site analytics for user behavior is often combined with a specific business environment and is driven by th

now let's take a closer look at the FileSystem class for Hadoop. This class is used to interact with Hadoop's file system. While we are mainly targeting HDFS here, we should let our code use only abstract class filesystem so that our code can interact with any Hadoop file system. When we write the test code, we can test it with the local file system, use HDFs when deploying, just configure it, no need to modify the code. A new filesystem interface was

style to. Let's take the example of a selector such as. Header ul {}.Assuming that this UL is the site's full-site navigation, it is located in the header, and so far is the only UL element in the header: header ul{} can actually take effect, but this is not a good way, it is easy to obsolete, and very obscure. If we add another UL to the header, it will apply the style we wrote to the navigation section, even if we didn't think of the effect. This means that we either refactor a lot of code or
