How to implement a simple asynchronous task scheduling function using MySQL and Ruby

How to use MySQL and Ruby to implement a simple asynchronous task scheduling function. Most of the previous web applications used a synchronous method to process requests, that is, after the user sends a request, the server will immediately process the request and return the result. However, as the complexity of applications increases, the processing efficiency of synchronous methods gradually becomes inefficient, so asynchronous task scheduling has become a common requirement in modern web applications. This article will introduce how to use MySQL and Ruby to implement a simple asynchronous task scheduling function, including task

Run a Qt application in different languages

Qt is a cross-platform application framework that is widely used to develop applications with graphical user interfaces. It is written in C++ and supports multiple programming languages, including Python, Ruby and Java. One of Qt's most useful features is its support for internationalization, which allows developers to create applications that can be easily localized into different languages and cultures. In this article, we will discuss how to run Qt applications in different languages. Introduction to Internationalization Internationalization, also known as i18n, is the process of designing and developing applications that can be easily localized into different languages and cultures.

Creating a content management system: organization and design

"Flat CMS design" web servers have become a trend. This only refers to content management systems (CMS) that do not store their information in a database. Instead, all information is stored in plain text files. Since many virtual private servers (VPS) now use RAM-based hard drives, this method is faster and more secure. In this series of tutorials, I'll show you how to create your own flat file system CMS using some standard web technologies. These systems are not as feature-rich as others, but have the basics of good response times. With all the information on a hard drive, file organization becomes a big issue. With this in mind, site information will be in a different directory than style and layout information. also

将Transforming a WordPress Server Dashboard into a Widget

In the previous article, we created the basic structure of the plugin. Now it's time to implement rendering classes for each widget. Recall that all widget providers must implement the Provider interface. They must also be located within a folder called widgets, under the namespace AX\StatBoard\Widgets. If we want to add a new indicator, just create a corresponding class and create an object and add it to the Widget class using the add_provider method. RAM Usage Widget The first piece of information we want to display is the amount of RAM currently in use and the amount of RAM currently free. In this case, free-m is our friend - it tells us

Connect React with other widely used web languages

React is a view library written in JavaScript, so it is agnostic to any stack configuration and can appear in almost any web application that uses HTML and JavaScript as the presentation layer. Since React is like the "V" in "MVC", we can create our own application stack however we like. So far in this guide we've seen React paired with Express, a NodeES6/JavaScript-based framework. Other popular node-based matches for React are the Meteor framework and Facebook’s Relay. If you want to leverage React in your existing project
