Tags: library sub-table compensation mechanism Message QueuingAs the volume of business increases in the production environment, the amount of database data can also increase dramatically. When the amount of data in the database reaches a certain level (database bottleneck), the host load of the database is very high, which can seriously affect the business, and seriously cause the database to be down.In order to avoid this extreme situation, we should make a plan before the occurrence, to solve

SSL programming OpenSSL is a product implementation of an open source SSL protocol that uses the C language as the development language with cross-system performance. The function that calls OpenSSL can implement an SSL-encrypted secure data transfer channel, which protects the security between the client and the server. Header file:#include #include The Ope

In enterprise app development, there is a unique notification push function for Apple devices to solve, especially when doing mobile IM, the APNs (Apple Push Notification service) requirements are relatively high, although there are special third parties to provide such services, But for the safety of the filter, the ability of the company would rather self-built push service system. I combine the development experience in the work, in this discussion of the

Sitch: In recent years, the 3G wave of China Telecom has been surging in the cloud, from the high-tech experience brought by 3G technology to the civilian population, various media are also not talking about the bright future of 3G. Unlike the "publicity" of 3G propaganda, there is another "dark stream" that is also unstoppable in the field of telecommunications technology, its emergence and development, it will also bring a brand new business experience to all telecom end users and non-end user

In the previous article I talked about a front-end separation scheme, this set of solutions in front of the server developers than in front of the Web front-end developers may get more applause, I think many senior front-end engineers see such a technical solution may have a kind of contradictory mood, When my work gradually toward more and more professional front-end development, I am often confused by this set of front-end separation scheme, recently I finally understand the source of this con

There are many things worth learning about switches and bridges. Here we mainly introduce the development and evolution of switches and bridges, also known as bridges, which are storage and forwarding devices connected to two local networks, it can be used to connect a network system with identical or similar architecture. This not only expands the distance or range of the network, but also improves the performance, reliability, and security of the ne

completed by the ATM access switch. The ATM access switch provides IP, FR, circuit simulation E1-E3, Ethernet, X.25.25 and other business interfaces through the ATM adaptation layer, provides high-speed Internet access, lan interconnection, voice, high-definition TVs, on-demand TVs, conference TVs, and other broadband services. ATM networks are generally called B-ISDN man. As can be seen from the above, ATM has the advantages of group switching and circuit switching, and is suitable for transmi

language that makes Web pages more simple to develop. However, the concept of documenting and structuring content with style sheets is much earlier than this. In a book, what kind of font you want, what kind of picture, how big the edge, is the style sheet to do, these concepts have existed for a long time. The electronic style sheet, which is expressed in computer language, has appeared in the middle of the 80 century.Let's just say that the ML came before HTML, and HTML was built on XML, and

ObjectiveIn the software design process, we always need to create many objects, and the larger the system, the more complex the objects are created. And today we're going to talk about solving the problem of object creation-the factory class pattern. To get close to the word factory, we use the example of factory-built cars to illustrate the evolution of factory-class patterns and what patterns to use in what scenarios.Scenario 1: A customer wants to
