object-oriented programming platform, so everything is an object. to download an HTTP file, we mainly use system. in the. NET namespace, there are two classes: httpwebrequest and httpwebresponse. Httpwebrequest can wrap a URL address and get an httpwebresponse object through the getresponse method. This httpwebresponse object contains the data returned by the HTTP server. In addition, I/O operations on the file system will not be mentioned. After all, it is only about key

and query it in memcached. In the design system, the design philosophy of Instagram is simple. It optimizes and monitors all content to minimize the O M burden. Its core principle is to keep it simple and never reinvent the wheel, use proven, stable, and reliable technologies as much as possible. Because there are only five technicians (only 2.5 backend engineers) and limited energy, choosing Amazon's cloud service is a good choice. Currently

The description of tools and technologies in the project is an important element of project management. The example in this project is as follows: Project Methods 1. the project adopts the relevant methodology of RUP and uses case analysis as the driving factor to obtain the relevant software requirement specification and case model. The architecture design is the core, based on the software requirements, the architecture is designed with a 4 + 1

After the introduction of the semantic web concept, researchers in Chinese institutions and universities have paid great attention to it. They have carried out in-depth research on the Semantic Web research content, some gratifying achievements have been made in the Basic Semantic Web theory and key platform technologies. The Semantic Expression Theory of semantic web is based on AI's research on knowledge expression in the past 40 years. Meanwhile,

Complete analysis of Android security attack and defense, decompilation and obfuscation technologies (I) I have been hesitant to write this article before. After all, it is not proud to decompile other programs. However, from a technical point of view, it is indeed a very useful skill to master the decompilation function, which may not be used very often, that's a headache. In addition, since someone else can decompile the program, we certainly have a

Multi-thread implementation1Multi-thread implementation(1): asynchronous Delegation(In essence, Microsoft will create a thread to execute tasks and use a thread pool to complete asynchronous tasks.) There are about three technologies for implementing asynchronous delegation: voting, waiting handle, and asynchronous callback.1.

interesting real-time engineering problems. In this report, I will explain how we can address these challenges and why we choose open source software to address them. The report covers the entire lifecycle of a tweet, from our backend service to front-end display. I expect the audience to have a better understanding and understanding of open-source technologies after hearing the report, and know what happened behind a simple tweet when it appeared in

responsibility should also be put into practice by team members, and constantly advocate efforts should be made to fulfill the commitments to form a pragmatic team style. Remember, responsibility is more important than "face", and responsibility is at the expense of everyone in the team, so no one can escape! Trust. Even if you have good technical skills and can plan your technical work as much as you can, you still need to trust your team members even if they know they will make mistakes. You

For a long time, I have found many people, including myself. When learning new technologies, there have been a lot of putting the cart before the horse. MVC and ORM are two typical examples. Implementation is separated from theory. In many cases, the focus of theoretical thinking is not necessarily the same as that of implementation. It is often even a certain idea that implements a framework. The role of the framework is to abstract the details of t

This article compares the IPSec VPN and ssl vpn technologies in detail, so that users from all walks of life can better understand the VPN technology and select the appropriate VPN product. Another VPN implementation technology different from the traditional VPN is the use of SSL-based VPN. This SSL-based VPN provides security similar to IPSec VPN. Because of the IPSec VPNArticleThere are many, so I will not go into details here, just explain the

From small to large, we have game dreams, so we hope to develop our own games. IPhone game development mainly uses these technologies and tools: Objective-C or C/C ++, xcode, uikit, quartz 2D, core animation, OpenGL, audio APIs, networking, and gamekit. Development tools and environment The language used for iPhone development is objective-C. Objective-C is an extension of C language, which gives C a simple and direct object-oriented feature.
