The so-called "Cloud" concept is to put databases and Management terminals remotely, that is, the cloud. Advantages of the cloud? 1. There are usually multiple servers on the cloud for redundancy, so it will not cause business Faults due to the failure of one server. 2. data can be stored on a remote server for a long time without being lost due to damage to the local hard disk. 3. The data server on th

High-definition TVs are becoming more common at home, and these high-definition TVs mostly have VGA, DVI, HDMI interfaces.

performance, stability, and functionality, and can achieve millions data storage. MySQL and web servers can be put together initially, but when the traffic reaches a certain scale, the MySQL database should be isolated from the Web server and run on a separate server while maintaining a stable connection between the Web server and the MySQL server.When database traffic reaches a higher level, consider using a solution such as a DB cluster such as MySQL Cluster or a library table hash.Overall, t

What the hell is a closure? Before JS inside heard some, but the actual development how do not feel how to use this concept? Just recently when learning laraval, found that the routing configuration is the closure function (the tutorial said that), do not understand what this closure means? I see the code and JS inside

tags in HTML5. As the name implies, these two tags are used to play audio and video. 8. A new formHTML5 has made a lot of changes to 9. Delete This improvement is beyond my comprehension. I don't think the removal of these two tags is a great help to the code improvements. The official explanation is that CSS should be used instead of the two tags. But I still f

Anyone who mentions static_cast, const_cast, reinterpret_cast, and dynamic_cast on the Internet will say that they have overcome the disadvantages of C-style type conversion and should use them.But what are the disadvantages of the C style? What are the advantages of C ++ cast?Before yesterday, I didn't even know what the cast was ). Yesterday, my colleagues ment

Action class:• Struts1 requires the action class to inherit an abstract base class. A common problem with struts1 is the use of abstract class programming rather than interfaces.• The struts 2 Action class can implement an action interface or other interfaces to make optional and customized services possible. Struts2 provides an actionsupport base class to implement common interfaces. The action interface is
