, principle and method 2 somewhat similar, zoom (ie turn to have attribute) can solve ie6,ie7 floating problem Advantages: Browser support is good, not prone to strange problems (currently: large sites are used, such as: Tencent, NetEase, Sina, etc.) Disadvantages: Many code, many beginners do not understand the principle, to use two code together to let the mainstream browser support. Recommendation: recommended, we recommend defining public classes to reduce CSS code. 4, parent P-defined Overf

Array Advantages: Fast query, if you know the index can quickly access the disadvantage: Delete slow, size fixed ordered array advantages: Faster than unordered array lookup disadvantage: Delete and insert slow, size fixed stack advantages: Provide last-in-first-out access method disadvantage: Access to other items is slow queue advantages: Provide first-in-out access method disadvantage: access to other The items are slow. List Advantages: Quick Insert, delete fast disadvantage: find slow (each

program is re-entered, you need to update the status in the main interface. For example, when I quit on my interface, the next time I log in again, if I don't update the state of the main interface. Will go directly to this interface about me. This demand is not the state we want.Let's look at the second architecture .　　It is clear that this architecture will be more clear and clearer. Let's take a look at the principle of this program: The architecture of this program is to manage the switch b

. When NAT is present, the initial design of the TCP/IP protocol process changes and the Internet can become very vulnerable.(3) Nat violates the design principle of the basic network hierarchical structure model. Because in the traditional network hierarchy model, the nth layer cannot modify the header content of the n+1 layer. Nat destroys the principle of independence for each layer.(4) Some applications are inserting IP addresses into the content of the body, such as the standard FTP protoco

code, or designing for a product setup, still doesn't look that smooth.3, the advantages and disadvantages of TRAC:Pros: Very flexible and can be controlled with SVN integrationCons: The function is not very powerful4, the advantages and disadvantages of Bugzilla:Advantages: Free, with Chinese version supportCons: Fast search results are inaccurate. Only defects can be managed.5. Advantages and disadvantages of Apple Xcode:Advantages: Very fast compilation, fast and easy for each operation. Aut

dynamically modifying the server weight during the HAProxy run.Whether it is STATIC-RR, Roundrobin or leastconn, are natural support weight. Only during run time, the STATIC-RR server weight cannot be changed or changed and is not valid. All cases where weight is 1 are a special case of the weight-based load balancing algorithm.HAProxy disadvantages are not introduced. In combination with the individual on the NIGNX part of the understanding, listed some HAProxy less than Nginx place, for refer

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

of the page class, so the usage differs from the session and application, as compared to the advantages of their cookie:1. Can configure Expiration time2. Simple: A cookie is a lightweight, text-based structure that includes simple key-value pairs3. Data persistence: Because it is saved to the client4. No server resources: Because the local client is storedDisadvantages:1. Do not store sensitive information in cookies, such as usernames, passwords, credit card numbers, etc.2. Encrypt the inform

to send an asynchronous request to the server via the XMLHttpRequest object, get the data from the server, and then use JavaScript to manipulate the DOM and update the page. One of the most critical steps is getting the request data from the server. To understand this process and principle, we must have some knowledge of xmlhttprequest.XMLHttpRequest is the core mechanism of Ajax, which was first introduced in IE5 and is a technique that supports asynchronous requests. Simply put, JavaScript ca

The amount of data on the site, do not recommend that you use DEDCMS, because according to the forum, 500,000 data is a bottleneck of Dede, at that time compared to phpcms, which is stronger than Dede; I also used both, personally think, Dede template settings, ad settings, Aspects comparative advantage, compared to phpcms, and data processing, membership and other aspects are not as phpcms, dede download and mail subscription and other aspects of the comparison is not how much. I did not excerp

unified Linux network management tools like Microsoft MMC; Windows has a more mature quick configuration tool. 　　 ⑤ ReliabilityPro Linux sounds Linux is open source, and open source is the power of the Internet. Open source means that there is never a limit and no one is "locked in".Pro Windows Sound Linux Desktop Interface Confusion (there are several KDE, GNOME, etc.), add menu inconvenient; Open source means: No road signs, no future, sellers can not earn money, there will be no sellers.The

standards of the Web.5.AJAX points of attention and applicable and non-applicable scenarios(1). Attention PointWhen Ajax is developed, network latency-that is, the interval between a user sending a request to a server to make a response-requires careful consideration. Not giving users a clear response, without proper pre-reading data, or improper handling of XMLHttpRequest, will make users feel delayed, which users do not want to see, but they do not understand. A common solution is to use a vi

1. Make complex projects easier to maintain by dividing the project into model View and controller.2. The view state and server form controls are not used, which makes it easier to control the behavior of the application3. The application uses a controller to control the request and can provide a rich URL rewrite.4. Better support for unit testing5. Better performance in team development modethe lack of MVC:(1) Increase the complexity of the system structure and implementation. For a simple inte

Python's syntax is simple--in the form of indentationThere are advantages and disadvantages of indentation:One of the benefits is forcing you to write formatted code, but it doesn't specify whether the indentation is a few spaces or tab. In accordance with established management, you should always stick to the indentation of 4 spaces.The second is to force you to write less indented code, and you will tend to split a very long code into several functions , resulting in less code being indented.T

complex point query Statements (tables, multiple subqueries, conditional mates) is very painful, and to use the tool to see whether the generated statements are logical, and can not be constantly debugging (I think the function is debugging out, the brain hole big open people can skip);EF Replacement version is really a pit, if you want to upgrade the program's EF from the lower version to the higher version, the higher version will be less than many methods (see the data is clearly written sql

. And RN is now divided into two sets of code, one is the Android is iOS. But the difference is not big. The UI written by HM has tried, it's a little bit uncomfortable, and it's very difficult to write the layout of the special dot. In this place RN has a great advantage.In terms of the cost of learning, I prefer RN, because the JS code of RN is react.js, but the use of JSX standards. The current contact of the two framework, I still prefer RN, although the development of HM is quite high effic

Polymorphic Parent-Child class transition conditions:The principle of forcing a parent class in Java to be cast to a subclass: the reference of the parent type to the instance of which child class, which can be converted to a reference to which subclass.Benefits of Polymorphism:You can accept arbitrary subclass objects as formal parameters.Disadvantages of polymorphism:You cannot use the unique properties and behaviors of subclasses.Java polymorphism pros
