Data sharing and synchronization between WEB servers is the core issue for multi-WEB deployment. In terms of data storage, Discuz data consists of two parts, one part of which is stored in MySQL database user, post, and other text and structured

1. Once in a wild era: Only "forms and hyperlinks" can be used for client-to-server submission, which may cause page re-loading problems. The real-time page has only a few changes, it can only be repeated. 2. If you can send an interactive request

The best way to learn is to link theory with practice. When we know how to penetrate an attack, someone will try to simulate a real attack. During Penetration, when we find that some ports are opened on a machine, you can think about how to use the

It has been a headache recently and how to implement the realtime graph. To sum up, we need to solve the following problems: 1. How to transmit Custom Data 2. What format should data be transmitted? 3. Can I perform partial refresh, that is,

Since go is a new language. There are still few wheels that have been created, and I like them very much. So let's talk about the IOC factory implemented with go today. The first code to be shared is the IOC factory, because I personally think the

Because of the problem, we know how to make progress. Several problems mentioned in "bad design" are what I have and are dealing. Some have been solved, and some have not yet. Many may ask why these situations have not been taken into consideration

Since reading the iron Xia series, I have never been tired of thinking about automation, monitoring, and warning. If you use an iPhone, you can use Siri on your mobile phone to perform operations (such as calling a contact) you want ). However, I

I usually use APIs, CDC, and encapsulated internal functions. It's easy to draw lines and circles... I recently learned about computer graphics and had to study the underlying algorithms internally... I will post a few codes here to share with you! (

When you hear the term "performance bottleneck", the main words that come into your mind are the central processor, memory, hard disk, and network. These are the main aspects to explore performance bottlenecks, but they are not the only aspect of

Virtual desktops simplify management, but need to be properly planned to eliminate storage performance bottlenecks, ensure performance and meet growth needs. The storage subsystem can simplify VDI deployment, but without best practices, its costs

In terms of function positioning, x86 is located on general servers, and Cert is positioned on key business application servers. Further subdivided, x86 can be divided into single-, dual-, and multi-channel servers, corresponding to Intel's 3000, 500

Now IT administrators urgently need to reduce costs and improve performance, so they try to put more computing capabilities into a smaller space. The establishment of a computing infrastructure using blade servers is undoubtedly a way out. However,
