Preface Today, in the Nuggets, I saw an article about the spring framework for the presentation, which referred to the face test of the cow net. So I downloaded the Cattle Network app, found the interview topic is very rich. I chose the Java aspect of the face test to do a bit. 10 topics for a group of interview questions, finished, I found myself a lot of wrong, most of them are basic questions. As the saying goes: The depth of the foundation determines the height of the future. I feel that I

value is auto, not a value of 2. My warm little heart, frozen in an instant, ah ~ ~ Application in However, for the General page (not similar to the game page, Slide page page), only certain art talents dare to increase the positioning attribute on the body (violate the principle of minimizing influence –part 7), therefore, set the Z-index property on the body general problem is not big, but, from the understanding of speaking, Z-index a little we

MySQL master-slave (MySQL Replication), mainly used for MySQL backup or read-write separation. Before you configure the configuration, configure two MySQL servers, and if your machine cannot run two Linux VMS at the same time, consider running two MySQL services on the same machine.MySQL Master-Slave principle is very simple, summed up:Only one master can be set from each.After the master executes the SQL, log the binary log file (Bin-log).From the connection master, and get Binlog from the mast

Tags: 2.7-mysql master-Slave configuration-1MySQL Master-Slave principle is very simple, summed up:Only one master can be set from each. After the master executes the SQL, log the binary log file (Bin-log). From the connection master, and get Binlog from the master, save in local relay-log, and execute SQL from the location you last remembered, and stop synchronizing once an error is encountered.Judging from these Replication principles, these inferences can be inferred:Master-slave database is

burden, if we can have a configuration to create objects, to manage the dependencies between objects, we do not need to through the factory and generator to create and manage the dependencies between objects, So do we reduce a lot of work, speed up development, and save a lot of time to do other things. The spring framework came out primarily to complete this function.In addition to helping us manage objects and their dependencies, the spring framework also provides facets-oriented capabilities

Sickle (4) in 1-2 years, will there be any change in E-commerce? These two days busy website, no intention to write anything, but in the Web site thinking, think is e-commerce things, I first said a conclusion: can defeat Ma Yun and net Sheng is not his current peers, but the new user needs and the resulting technological innovation. Just like Google beat Bill, new user needs and technological innovation determine who wins, not capital and strength, w

In my article, "C # interface-based programming," I talked about the advantages of using an abstract interface as a programming paradigm. The separation of interfaces and the execution process is now definitely not a new idea, but it is actually the core of COM programming. Perhaps the interface based in the salient feature is polymorphism and instant check (RTTI). RTTI allows the client program to access the object at run time. For example, if an obj

If you are involved in a business problem, I may not be able to do too much elaboration. But there are some basic principles and techniques to deal with. Important words are generally bold ... An experienced person can look at the bold content directly. Except for the first one, other beginners can skip. Communicati

Label:In the first few chapters of this book, you have learned about various types of replication and how to quota the various kinds of scenarios. Now is the time to make your setup more reliable by adding monitoring. In this chapter, you will learn to monitor what is going on and to implement a reasonable monitoring vehicle such as deterioration. You will learn: • Check your XLOG archive • Check the pg_stat_replication system view • Check OS-level replication-related processes At the end of thi
