While RIAs provides notable advantages for web development, it also has the disadvantages of browser plug-in technology. The following are the main disadvantages of RIA: 1. Sandbox) Because RIAs runs in a sandbox, they are restricted to access system resources. If users modify their systems or reduce the permissions of RIA to access system resources, RIAs may fail. 2. Disable scripts On the client side,

easy to start, and it is almost doneContinuous running requires a restart even if it runs for several months. The software version can be upgraded even when the service is interrupted.3. Simple nginx configuration and complicated ApacheNginx static processing performance is three times higher than ApacheApache's support for PHP is relatively simple. nginx needs to be used with its end.More Apache components than nginxNginx is the first choice for Web Servers4. The core is different from the Apa

Original article, reprinted Please note:Reprinted from All-iPad.netLink:Advantages and disadvantages of Corona SDK If you are using or planning to use corona SDK, you certainly hope that the more features, the better, the more advantages, but in fact, any SDK has its applicability, there are specific user groups, so there must be some less outstanding places. Someone made some comments on corona on the monkey (http://www.monkeycoder.co.nz) Project

This article is not a discussion session, nor a cookie, now many sites are talking to put cookies, called cookies based session, the following is to discuss the advantages and disadvantages of the cookie based sessions: Advantages: 1. Reduce server pressure, such as PHP session by default is the file storage format, which will be less disk pressure, will not cause more fragmentation of the disk.2. When you do the cluster, is not to do session synchr

deletion and recovery mechanism When a file is deleted from HDFS, the file is not immediately deleted from HDFS, but renamed to the/trash directory, as long as the file is still in the/trash directory, this file can be quickly recovered; The file storage time in the/trash directory can be configured (6 hours by default). When this time is exceeded, NN will delete the file from the namespace; Deleting a file will release data blocks related to the file. Note: there will be a certain delay b

good starting point. 3. page navigation: page navigation will be a future direction. In fact, this will make the system context clearer. With a configuration file, you can grasp the relationship between all parts of the system, which is of great benefit for later maintenance. This advantage is especially evident when another group of developers take over the project. 4. Provides the exception handling mechanism. 5. Database Connection Pool Management 6. Support for i18n

The main way of hosting information in the Web is the picture and text, the following is the advantages and disadvantages of some Web image format to summarize.1. GIFGIF is one of the more ancient web image formats, dating back to 1987, and almost all browsers support this format, old and old. GIF is an indexed-color-mode picture, so GIF shows a maximum of 256 colors per frame. GIF is capable of supporting animations and background transparency, which

and efficient, and can be considered as the perfect solution for real-time application systems in data-intensive distributed deployment environments. node is ideal for scenarios where you anticipate a high level of traffic before responding to the client, but not necessarily a lot of the server-side logic and processing required.node.

--kmeans specific explanation see Data Mining Algorithm Learning (a) Kmeans algorithm? Core idea: enter the number of clusters K, and the database containing N data objects. Output k clusters that meet the minimum variance criteria? algorithm Advantage: faster than KNN? algorithm Disadvantage: the number of clusters K is an input parameter. Inappropriate k-values may return poor results? application area: picture cutting. Analyze product similarity to classify commodities, analyze the company's

Comparison of the advantages and disadvantages between Apache and Nginx1, the advantages of nginx with respect to Apache:Lightweight, same Web service, consumes less memory and resources than ApacheAnti-concurrency, Nginx processing requests are asynchronous non-blocking, and Apache is blocking type, in high concurrency, nginx can keep low resource consumption and high performanceHighly modular design, relatively simple to write modulesCommunity activ

A period of time to interview, was asked a question, suddenly do not know how to answer, and then check the check, just know how it is, now summarize it. The copy constructor and assignment operators are used to create a copy of the object. In some cases, the copy constructor is implicitly called by the compiler, such as when the object is passed by value. Advantages: Copy constructors make it easy to copy objects. STL containers require all content to be copied and assigne

(); } An object adapter can fit multiple classes with a suitable fit. You only need to pass different matching classes in the adapter construction method. With flexibility. Advantages of class Adapters: 1, because the adapter class is a subclass of the adapter class, it is possible to replace some adapters in the adaptor class to make the adapter more flexible. Disadvantages of class Adapters: 1, for Java, C # and other languages that do

above summarizes the implementation of three kinds of inheritance methods. But each method has its advantages and disadvantages. If the parent class is like this: Parent function Person (hair,eye,skin) { This.hair = hair; This.eye = eye; This.skin = skin; This.view = function () {return This.hair + ', ' + This.eye + ', ' + This.skin; } } How the subclass should be designed so that the subclass man passes argument

Now backbone, Emberjs, Spinejs, Batmanjs and other MVC frameworks have come to the attack. Commonjs, AMD, Nodejs, Requirejs, Seajs, Curljs and other modular JavaScript are coming. Web front-end has evolved into a large front-end, the Web front-end development faster. 1 Let's see what modularity is? Modularization is a method of separating the system into independent functional parts, which can be divided into separate functional parts, which strictly define the transparency between module in

Commonly used EJB, RMI, Web Service, as well as Hessian, NIO, and so on, their advantages and disadvantages compared to the following: 1:ejb Advantages: Good scalability, strong security, support distributed transaction processing. Disadvantage: Can not cross language, configuration is relatively complex, different Java container is difficult to do seamless migration. 2:rmi Advantages: Object-oriented remote service model, based on TCP protocol

Detailed introduction of the advantages and disadvantages of the CSS framework for your reference. the benefits of CSS frameworks : 1, the development efficiency enhancement.If you are a front-end development of a corporate site, believe that most of the time to do similar sites code work. A well-defined framework can greatly improve your productivity and avoid some common mistakes. If your job is to be billed on a per-piece basis, you will be paid m

variable directly when you want to use it, rather than declaring it in advance, which is close to the use of variables in VB. After you use it, you do not have to consider releasing it because it is automatically released. Disadvantages The session variable and the cookie are of the same type. If a user sets the browser to be incompatible with any cookies, the user cannot use the session variable! When a user accesses a page, the running environme
