1. Advantages and disadvantages of Microsoft TFS:Advantages: It is the support of agile, Msf,cmmi and other projects, process management, process improvement. On the task page, you can take a glance at the requirements and project progress, which is more useful for small teams than Gantt charts.Cons: The number of teams and companies that can be applied is very small, most really used, that is, the source code management part, which is only a small part of the TFS function.2. GitHub's

"08"what is a CSS sprite? What are the pros and cons? Concept: Stitching multiple small images into one image. The background pattern that needs to be displayed is adjusted by background-position and element dimensions.Advantages: Reduce the number of HTTP requests, greatly improving page loading speed. Increase the repetition of picture information,

performance barriers:2) Session Bean A schema that uses Hibernate to improve the development efficiency of the above architecture:3) Session Bean The above 3 architectures are analyzed:1. Memory consumption: The JDBC Architecture 2 is undoubtedly the most memory-saving, hibernate architecture is the second, EB Architecture 1 is the worst.2, operating efficiency: If JDBC code write is very optimized, then the JDBC schema is the most efficient, but the actual project, this is almost impossible, w

that processing 10,000 non-blocking IO requires no more than 10,000 threads, and you can use 1000 or 2000 threads for processing. Because the non-blocking IO processing connection is asynchronous. When a connection sends a request to the server, the server treats the connection request as a request "event" and assigns the "event" to the corresponding function. We can put this handler function in the thread to execute and return the thread after execution. Such a thread can handle multiple event

, of course, git can also be restored through the historical version, but it is not easy to implement a partial restore.In short, the company's development team in the complex multi-project development, SVN is a better choice.Sign up: I found Git's website and followed http://www.aehyok.com/Blog/Detail/73.html and http://www.cnblogs.com/greyzeng/p/. The 5046776.html method is registered well. There is nothing to solve the problem, but still hope to launch the Chinese version of the ~Successful

not appropriate to use it alone.The technique for solving this problem is to borrow a constructor, that is, to call the parent type constructor inside the sub-type constructor. This allows each instance to have its own properties, while also guaranteeing that only the constructor pattern is used to define the type. However, the result of using this method is that you cannot get the common method of the parent class, that is, prototype the method of b

efficiency. NBSP; 2, the connection between the view and the controller is too tight. Views and controllers are separated from each other, but they do have a tight connection, the view has no controller, its application is very limited, and vice versa, which prevents them from being reused independently. NBSP; 3, view low-efficiency access to model data. Depending on the model operator interface, the view may need to be called multiple times to obtain sufficient display data. Unnecessary freque

The pros and cons of blocking and non-blocking IO packages in Java the cornerstone behind the NIO design: The reactor pattern, the architecture pattern for event multiplexing and dispatch.Reactor (Reactor): Architecture pattern for event multiplexing and dispatch typically,

lifetime of the content pointed to by the pointer (which may require the programmer to delete the requested memory at the appropriate time, but because of the efficient insertion/deletion of the pointer), the use of boost::any may avoid this situation, because we can store the type itself (of course, the pointer can be stored). This is one of the advantages of Boost::any.Boost::any Another advantage is that you can store any type. The previously mentioned mylist can only hold pointers to BaseCl

the permission control file as SVN supported UTF-8 format, a library can have multiple working directories but only one library can be used for a working directory although the location of the library may be changed but strict requirements, the library file storage method, do not see the real content of the file4. Advantages and disadvantages of Microsoft TFS:Advantages: It is the support of agile, Msf,cmmi and other projects, process management, process improvement. On the task page, you can t

table from one or more tables, which is actually a query result, and the query that corresponds to the name and view of the view is stored in the data dictionary.(2). What are the pros and cons of views?A. Data security.Define different views for different users so that users can only see data about themselves. The database Authorization command enables each user to limit the retrieval of a database to a s

Factory mode is a design pattern of creation, it accepts the instruction, creates the instance which conforms to the requirement, it mainly solves the unified distribution of the resources, the creation of the object is completely independent, so that the object creation and the specific use of the customer is irrelevant. Main application in multi-database selection, class library file loading and so on.　　　The strategy mode is to solve the policy swi

1. Object Encapsulation Method 1) Raw schema generation objectDirectly writes our members to the object and returns with the function. Cons: It's hard to see a pattern coming out of an instance.functionStu (name, score) {return{name:name, score:score}}varSTU1 = Stu ("Zhang San", 80); varSTU2 = Stu ("John Doe", 90); Console.log (Stu1.name); //Zhang San1) Generating a constructed mode objectJS helps us to pro

, Git is suitable for simple software projects, typically some open source projects, such as the Linux kernel, busybox, etc.Instead, SVN excels at multi-project management.For example, you can store a bsp/design document/File system/application/Automation compilation script for a mobile project in an SVN repository, or a file system that stores 5 mobile projects in one SVN.The n (number of items) * m (Number of components) warehouse must be establishe

receive traffic httpclient maximum, httpurlconnection and volley the same, okhttp slightly larger than the former two.5, the average time-consuming networkError description: The condition of the network may affect the network request time.Conclusion: The average time of network request is httpclient maximum, the httpurlconnection is the smallest, and the volley average is higher 10ms~20ms,okhttp than volley 20ms~40ms.The final conclusion is drawn:1 , for new applications, you should be more inc

Allegro is more convenient for multi-person collaboration.What are the hazards of the main components of the substrate (FR4) and PP plates and the Chinglei rays?Commonly used FR-4 and P.P. Board, the main ingredient is epoxy resin and glass fiber . The harm you refer to, should only be the Chinglei after the shooting process will produce harmful substances.

the MFC SDK for free.QT is free to get its GPL-compliant version on UNIX (note: The GPL version is now available for free on Windows). If you want to develop software that is unfair to open source code, you must purchase QT authorization. Under specific platforms, each developer buys a permanent license and receives one year of technical support.
