From this function, we can see that Chrome uses wsaeventselect to establish a connection with the server. Although the performance of wsaeventselect in terms of throughput and multi-connection processing cannot be compared with the overlapping I/O and Completion Ports, however, it is enough to use the client, and wsaeventselect does not need to be associated with the window handle as wsasyncselect does. It can also reduce the Coupling Degree of the network. It should be said that it is a good ch
open debug, debug will not go to the syslog, so there will not be too many UDP connections, you will not know that there are memory leaks, let's see why this leads to memory leaks, first look at the GetLogger code:

Two months ago, at the invitation of the editor of the silver bullet magazine, he wrote an article on "process" and "microkernel, the title is "microkernel process engine design ideas and architecture ". Now the seventh issue of panyuan magazine has been published, and the full text is now transferred to my blog.
The original address of the silver bullet: http://gocom.primeton.com/modules/gSpace/modules/techresource/article1803.htm
After reading this article, I will read "Demystifying jbpm Proc
deployed SOA object based on Web Services must be divided into two stages. The central task in these two phases is to identify the service, and these services must be:
Developed using the new execution environment: requires the development of new application logic in the form of Java classes and ejbs to run in the WebLogic application server container.
To support existing application logic: you must use a tool set that is suitable for existing technologies and supports Web Services.
component technology provides clear support for SOA construction and is based on industry-recognized standards, the above two factors impede the implementation of reuse at the enterprise level. Note that the actual situation is even worse, because to use these standards-based technologies, enterprises need to make the system based on specialized middleware technologies, such as MQ and tibco. All these systems, whether based on standards or specialize
I had this idea for a long time and wanted to visit the first-line enterprise software technical experts in China. Because their perspective allows us to see the most authentic Chinese enterprise software market. At the same time, you can also listen to their stories about Chinese software people.
Today, according to a friend from infoq in China, he happened to be Hu Great Wall, a technical expert in enterprise workflow management. He is a person who is willing to share with others, A typical

2. Use the Java Server Pages (JSP) model when data is passed to the JSP pageWhile this scenario is fairly good, the development team finds that the number of data to be displayed on the page is too large, which can discourage users from using interest. In addition, in terms of efficiency, the exchange and transfer of graphic data is particularly slow. For example, Iconix confidence Interval graphic--is used to display scanned gene expression data, which takes at least
look very much like desktop applications, so it doesn't seem to have any new technology for developers. Analysts and developers who do Ajax also think so.
Zapthink, senior analyst Ronald Schmelzer, said: "Google has organized a large team of Ajax developers to develop Ajax services, but Google is a company with billions of dollars, so it has the ability to do so." ”
On the other hand, many companies are not able to hire such an AJAX dream team. And as long as Google needs to develop A
used to display scanned gene expression data, which takes at least 2-3 seconds to load, because this scenario requires a dedicated graphical servlet to display each of the graphs individually.
Examples of Drugmatrix confidence Interval graphic
Note: This figure contains the Drugmatrix confidence Interval Graphic, which is displayed instantaneously through an HTML form vector pattern.

Many people know the implementation of interfaces, but the implementation method of interfaces is dividedDisplay implementationAndImplicit implementationI don't know if many people know it! However, I think the company's technical department seldom mentioned this. I just want to write this blogs.
Common Methods:

This method isImplicit implementation:

This method isImplicit implementation:

You can call the GetReviews method.

Tip: because it is a desktop component, you do not need to use the activity interface for the time being. Of course, you may need to jump to the activity application for operations when you click it during project implementation, A typical case is the music player provided by Android.

First, the local variable B (used to store the byte array that needs to be put into the memcached server) and flags (used to store the flag information) are affirmed ). Then, judge whether the object o is of the string type and long integer type, and encode the object o into the corresponding byte array and store it in the local variable B.
Pay special attention to row 3. When the o type is not a string, basic type packaging type, or byte [] ar
