What we get from the MySQL replication function is bitsCN.com. MySQL databases support single-item and asynchronous replication. During the replication process, one server acts as the master server, and the other server acts as the slave server. As shown in. The master server writes the update information to a specific binary file. An index of the file is maintained to track log loops. This log can be recorded and sent to the slave server for updates. When an slave server is connected to the mas

The benefits of using pointers for function parameters,The first step is to understand the process of function parameter transfer, which is a copy type, for examplevoid Modify (int a){a++;}void Main (){int a=5;Modify (a);printf ("%d", a);}After the execution of the program, the value of a is still 5, for what, because in the execution of the Modify function, is another open storage space, the value of a copy of the past, and then the Modify function t

One of the benefits of conditional expressions is that you make your code more concise, for example, in a scenario where you need to collect different values based on different criteria, the code in most languages is as follows:1 varTMP =0;2 3 if(Conditinon1)4 {5TMP =xxx;6 }7 Else if(condition2)8 {9TMP =yyy;Ten } One Else A { -TMP =zzz; -}It's much easier to use Scala, which is all expressions, and the code looks like this:1 varTMP =2 if(Conditinon1)3

Recently, I felt deeply that a new era of front-end engineers need to have the thinking of senior Sheng.At first people are also a one by one strokes to complete their own work, the completion of a finished product needs to consume a lot of time.Slowly people find that writing to write is the words, so there is a movable printing ....The change of the front-end engineer thought has appeared the component development .....What are the benefits of compo

What benefits does Google I/O 2015 bring to Android developers?yesterday, in the garage coffee, and a group of old friends spent a happy Google night. The first thing to say is that this year's update some not to force, at least not enough Geek. I also do not intend to take stock of some of the information in the Keynote, presumably a lot of people have seen at various sites do not know how many times, I would like to say some is about this Google I/O

1. What are Web standards?A "web Standard" is a general term for a series of standards. The common misconception is that Web standards are often said to be div+css. The exact phrase should be: using XHTML1.1 in the Web standard recommended by the website to combine CSS2.0 style sheets to create pages. A DIV should refer to an XHTML tag, whereas a CSS is a style sheet.2. Benefits of using Web standards development2.1 Savings in operating costs2.2 User-

1. What is a singleton modeSimply understood, there is a class that can have only one instantiated object, which is the singleton pattern.2. Benefits of GetInstanceFirst look at how to use getinstance to implement singleton mode Public classConnectionPool {Private StaticConnectionPool Pool; //other member variables//... PrivateConnectionPool () {DS=NewCombopooleddatasource (); } Public Static FinalConnectionPool getinstance () {Try{Pool=NewConn

Package.json are used to obtain the pkg.The source and destination files are configured in "Build". That is, who is required to compress? Who will be generated after compression? Note that we will name the file name of the target files through the name and version of the Pkg.(PS: The contents of the Package.json mentioned above have finally found the place where he was applied.) The benefits are: for example, the management of the file version, you o

[Finally understand] the benefits of adding PHP to a namespace-facilitate automatic loading and finally understand the namespace A PHP project usually has only one entry file index. php. We usually write an automatic loading function in this entry file to the class file that will be instantiated by require later. For example: Spl_autoload_register (function ($ className ){Require 'class/'. $ className.'. php ';});Through the above Code, we found that

provides 300M wireless at the same time, through the existing power line network in the home wall, transmits the signal to the remote Hyfi Extender tl-h29e (can be inserted on any socket) at 500Mbps wire speed. The tl-h29e will then convert the received wired signal to 300M Wireless. In this way, plug in the Hyfi product place, you can have Wi-Fi, wireless blind spot to complete cleaning. Intelligence refers to the Tp-link Hyfi products with automatic configuration push technology, network con

Let's start by explaining what the benefits are:1, if you want to new an empty list, and this list will not add elements later, then use Collections.emptylist () good.New ArrayList () or new LinkedList () will have an initial size at the time of creation and will occupy a memory.Every use of new an empty list collection, waste is a big one, waste is serious, it is not good2, in order to encode the convenience.For example, a method return type is list,

What are the additional benefits of shared_ptr (sp)? Destructors can execute normally even if they are converted to a base class.Two classes knownClass foo{};Class Bar:foo{public:~bar () {}};First look at the situation without SP.bar* obj = new bar ();Delete obj;This way Foo does not have a virtual destructor, and when the Foo object is deleted it is not called to the bar object's destructor.If you use an SP, you can refactor normally.spshared_ptr add

Original linkIn the first article, I introduced the basics of Rxjava. In the second article, I showed you the power of the operator. But you may still not be persuaded. In this article, I'm going to show you some of the other benefits of Rxjava, which I believe is enough for you to use Rxjava.Error handlingSo far, none of us have introduced the OnComplete () and onerror () functions. These two functions are used to inform subscribers that the observed

need to dynamically load the driver class according to the actual situation, this time the reflection is useful, assuming Com.java.dbtest.myqlconnection,com.java.dbtest.oracleconnection These two classes we want to use, this time our program is written more dynamic, through the class TC = Class.forName ("Com.java.dbtest.TestConnection"), which allows the JVM to find and load this class in the server through the class's full class name, and if it is Oracle, the passed-in parameter becomes anothe

So many people in use, Linux in the end have hair benefits?In fact, I am not very clear, some people say free, but everyone use Windows also do not have money. I think in the Celestial kingdom, the money is not much software. A son does not have to spend. Sincerely thank those Daniel who serve the people.Now, in addition to doing some simple development on Ubuntu, the other features, really did not use the heart.The first motive was to play, as if it
