With the development of computer technology, network communication technology and information construction, the number of computers and equipment in enterprise data center is increasing, and the engine room has become an important hub for many enterprise data operation. A secure, efficient, operational data center, and its fine-grained management are the focus of more and more businesses. The introduction of a full-featured, high-intelligence operation and maintenance system, the basic environme

The wait/notify mechanism is designed to avoid the performance loss caused by polling. To clarify the truth, we use the classic example of "library books" to explain. A book can only be lent to one person at a time. Now there is a book, the library has borrowed the book John. Under the simple synchrnozed synchronization mechanism, if Li Si wants to borrow, first must go to the library to check whether the book has returned. Lee Four is a impatient per

Ajax Polling request status is very important in Ajax learning is also necessary to grasp the knowledge point, today and everyone to share this part of the content, together to see it. the function to be implemented here is to log in to the website by scanning the QR code of the public number with parameters. but obviously, if Ajax continuously requests the server, this will aggravate the load of the server, so this example uses the JS setinterval to

The traditional Ajax polling method, the customer service side at the user-defined time interval to the server to query the latest data. This method of pulling data takes a short time interval to ensure the accuracy of the data, but too short a time interval the customer sends multiple requests to the server in a short period of time. Reverse Ajax, which is called long polling or comet. The server and custo

There are projects that need to use Silabs's c8051f850. In fact, the most important is to fancy the price, as well as its working temperature. So we need to start learning this film. The simplest ADC routines are as follows:Initializes the system clock, initializes the IO, and so on. The P1.0 is led output and the P1.2 is the ADC input. The ADC uses VDD and GND as the reference source. and use polling in a way that is not interrupted.void c8051f850_io

The message communication process can be polling or interrupted. This article attempts to analyze a defect of the polling method. Framework of the general round robin method: Bool have_msg = false; SmallProgramThere is no problem in using this method. However, if the communication library that undertakes underlying communication tasks in a complex system is designed in this way, it will br
