technique for creating fast, Dynamic Web pages.　　The ability to update parts of a Web page without reloading the entire page. Ajax enables Web pages to be updated asynchronously by exchanging small amounts of data in the background with the server. This means that you can update a part of a webpage without reloading the entire page. Traditional Web pages (without Ajax) if you need to update the content, you must reload the entire page page. 2.2 Effects:2.2.1 Ajax uses asynchronous data transfer

Forward forecast: 21st century will produce eight future technology series A What happens if eight different technologies are present at the same time. In this respect, Peter Diamandis on February 8, 2016 to discuss his views. Here, I will share a series of blogs with my readers, and in the blog Peter will describe the following areas that will change and be combined to create an unexpected future. So what do these areas include? Calculation Internet

like art to learn CSS, because it is to see others learn, so learn, do not learn no advantage! This kind of pressure is very small, not learn and art this bowl of rice. reason two: just amateur study, this study is just a play, because you do not have to use this technology to eat. reason three: the method is wrong, some people just look at the tutorial, but he does not do, I used to see too much, do too little, so have the practice you can put the t

With the development of China's communication industry, vro technology is widely used. So I have studied the role of vro technology in the development of the network. Here I will share it with you, I hope it will be useful to you. With the rapid development of network applications, especially video and voice applications, the Data Types of voice, video, and other large data volumes must be frequently transm

[Peer-to-peer technology] Front-end technology-how to reconstruct, build a blog, and learn how to develop automation. In the article "Summary of first-to-second reading materials from the front-end to the great god", I introduced in depth the front-end beginners and advanced technical materials, today, xiaobian continues to publish five dry articles on front-end learning. Let's take a look! In addition, en

UWP hand-drawn video creation tool technology sharing series, uwp tool technology The final product of hand-drawn videos is video files. The previous articles mainly focus on the creation of hand-drawn videos. Today we will talk about the export of hand-drawn videos. This article mainly uses UWP as an example. In addition, we will introduce some Web-side problems and solutions. As mentioned above, after a h

In the previous article, we will introduce anti-simulation technologies commonly used by malware to readers. In this article, we will introduce various anti-Debugging techniques used by malware to impede reverse engineering, so as to help readers better understand these technologies, this enables more effective dynamic detection and analysis of malware. I. Anti-debugging technology Anti-debugging is a common anti-detection technique, because malware a

1. What is Java IDL? ---- Java IDL (Interface Definition Language) can realize the interaction between objects on different platforms on the network. This technology is based on the description of the Common Object Request proxy architecture (CORBA) specification. IDL is an interface definition language that does not depend on a language. All languages that support CORBA have the IDL ing of IDL to this language. As its name indicates, Java IDL support

I recently applied the Java RMI technology, so I will summarize the use of RMI. In addition, the implementation of EJB is also based on Java RMI. RMI remote method calls can be called across machines through the network, but Java RMI only supports Java programs on both sides. To achieve completely heterogeneous on both sides, you need to use the legendary web service. Two or more projects should be established to ensure good results. Of course, if you

Why study Oracle technology ?, Learning Oracle technology? As we all know, Oracle accounts for more than 48.1% of the market share in the enterprise database field and has become an absolute leader in high-end enterprise database software. With the passage of time, the scale of enterprise databases continues to expand, and experienced senior OracleDBA has become increasingly popular with enterprises. We c

CoreLocation technology and corelocation Technology The CoreLocation framework can be used to locate the current longitude and latitude of a device. Through this framework, applications can use nearby cellular base stations, Wi-Fi signals, or GPS information to calculate user locations.Three modes supported by iOS positioning. (1) GPS satellite positioning (2) base station positioning (3) WiFi iOS developer

SharePoint and Ajax technology (1): Ajax technology learning The previous article introduced how to build an Ajax environment on vs2008. This article can be said to be a learning note. I read the content of the learning video http://www.asp.net/ajax. 1. Open the last created Ajax 1.0-enabled ASP. NET 2.0 web site. Open default. on the ASPX page, under the design view, you can see that there is a scriptmana

HP iLO technology and HPiLO Technology 1. What is HP iLO? Reference a description in Wang chunhai's blog "using iLO to remotely manage HP Series servers: ILO is short for Integrated Ligths-out, which is an Integrated Remote Management port on the HP Server. It is a group of chips Integrated with the vxworks embedded operating system, connect to the switching machine in the working environment through a stan

According to the reporter's understanding, at present, the only professional Mesh-Wifi equipment manufacturer in China -- Shanghai huichuang communication (GBCOM), in its MESH network, uses the multi-hop feature, A non-conventional seamless coverage technology-MESH terminal relay was developed. Multi-hop refers to the use of a terminal as a relay in the tr

this gets the approximate time required to complete the project. HoweverIn fact, each project encountered a two or three bottleneck during the development process. These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who do not understand the complexity of the assessment. They don't understand how it's going t

UWP hand-drawn video creation tool technology sharing series, uwp tool technology First, let's talk about the original intention of writing this article. At the beginning of the painting, I read through the UWP App code and found that there are indeed many advanced technical points, but also many problems, such as scalability, coupling, performance, and functions. So we decided to reconstruct this product f

I. Introduction With AJAX technology, a browser page can send data requests to the server in the background while the front-end user interfaces remain active. This leads to a typical problem-the previous two activities simultaneously access common JavaScript and DOM data structures. Traditionally, the solution to this concurrent programming problem is not provided using JavaScript. This article describes an improved and proven mutex mechanism-it can i
