This article mainly introduces PHP + jquery's method of displaying the number of online users in real time, and analyzes in detail the principle and code implementation skills of displaying the number of online users in real time, which has some reference value, for more information about how to display the number of o

The first two years have been a socket based flash chat code, but not all cases will choose (or have the conditions) to use the socket of the server. Real-time communication based on HTTP can be used in programs that are not too high on the demand for immediacy. The principle is to obtain information through the client request, if there is no need for content, the background program will wait for a period

There are generally two ways to achieve real-time communication:Socket or comet. Socket is a good solution, the problem is not all browsers are compatible, server-side implementation is a little bit cumbersome. By contrast, comet ("Server Push" based on HTTP long connections) is easier to implement and compatible with all browsers. So this time it's about Comet's

A process is running and constantly writing logs. You need to monitor log file updates in real time (usually used in debug). What should you do? Keep opening and closing files? No. There are at least two methods from two frequently-used commands: Tail-F log.txt, another process is writing logs, and you can use tail to print new content in real

Instructor song,Hua Qing vision embedded college lecturer. 1.1 Introduction to rtc In an embedded system, RTC is usually used to provide reliable system time, including hour, minute, second, and year, month, and day, it is also required that the system work properly when it is shut down (usually powered by a backup battery ). Its Peripheral does not require too much auxiliary electrical channels. Typically, it only requires a high-precision 32.768khz

Lucene often encounters real-time search scenarios when searching within the site, such as the user search function. To implement real-time search, the most common practice is to add a new document, call IndexWriter's Commit method to submit an in-memory index to the hard disk, and then reopen Indexreader to search. Ho

In a recent project, a high-precision real-time clock is required under VxWorks, with a precision of 1ms and an overflow time of more than 5 hours. The VxWorks provides a system clock that starts counting after the operating system starts, with a precision of 1 ticks, and can get the current count value through Tickget

In addition exec executes the SQL statement directly, essentially executes the concatenation of the SQL string, sometimes it is difficult to stitch the variable into the string (in the end need a few single quotes), and sp_executesql is much clearer Declare @SQL nvarchar( -),@Name nvarchar( -),@Count int,@ID nvarchar( +) Set @Name=N'Cat' Set @Count=0 Set @ID=N'{00000000-0000-0000-0000-000000000000}' Set @S

The systems we typically use, whether Linux or Windows, are non-real-time systems. Non-real-time systems can obtain very accurate current time, even by reading some of the CPU's registers to get a CPU cycle count clock, it is esti

HTML5 has many notable new features, such as Canvas, local storage, multimedia programming interfaces, WebSocket, and so on. Although everyone is very enthusiastic about it, I personally think it requires the support of other platforms to truly "fire ". I used to explain in detail other methods such as ajax-based "polling" and "long polling" during web communication. Round robin: This is the earliest solution to implement real-
