Laravel describes how to build real-time applications. Instant interaction applications We should all understand that in modern Web applications, instant messaging is required in many scenarios, such as the most common payment callback and third-party login. These business scenarios basically need to follow the following process: The client triggers related services and generates operations (such as paym

After listening to the preface, you can't wait to see what samza is? First, let's take a look at samza's background as essential (at least the first on the official website). What technical background do we need to learn about? What is messaging )? The message system is a popular solution for implementing near real-time asynchronous computing. When a message is generated, it can be put into an activemq (rab

MYSQL triggers SQL SERVER instances in real time. The following describes how to update a mysql data table to trigger the addition, deletion, and modification operations on the corresponding table in SQL server. First, add the triggers for the original mysql table, including the following three: INSERT data: delimiter | drop trigger if exists t_afterinsert_on_accounts | create trigger t_afterinsert_on_acco

After the user generates a takeaway order, you can send a text message to inform the store to have an order, but the shortcomings of the SMS method is very obvious, if you want to let users and websites know that the store to accept orders and other operations need site human intervention, which is not available befo

In addition to using the same technology as the magic wand in Photoshop, or a similar color-range algorithm in the selection menu in Photoshop (the two I have at least 90% consistent code) is to implement a simple cutout, now some state of art algorith

--exclude INotifyINotify is a Linux feature that monitors file system operations such as read, write, and create, triggering inotify when a file system changes. INotify provides the Inotify-tools tool, which contains two functions, one is inotifywait to monitor file system changes, and the other is Inotifywatch, which is used to count the number of file system accesses. This time we use inotifywait with rsy

Recently, the feature of Kinect posture recognition based on machine learning has been completed. However, the light does a corresponding posture, collect the identified data, always feel passable, less something. And sometimes because of the distance from the Kinect of the situation, the scene interface nothing, had to rely on the feeling to adjust the position. There is, in the face of hundreds of data per second results, it really does not look. So I came up with the idea of whether the colle

bolts processes and produces a new output stream. Bolts can perform actions such as filtering, aggregating, joining, interacting with the data source and the database. The bolts receives data and emits it to one or more bolts. "IBolt" is the core interface to implement bolts. Some common interfaces are irichbolt,ibasicbolt and so on. 　　 Let's look at a real-time example of "Twitter analytics" to see how to

I. Setting of the Sphinx Incremental IndexThe data in the database is large, and new data is added to the database, and you want to be able to retrieve it. All re-indexing is very resource-intensive because we need to update the data relatively rarely. For example. The original data has millions of, and the new one is only thousands of. This allows for near real-time updates using the "primary index + Incre
