In Ubuntu, like in other Linux versions, the swap file is a key part of managing the computer’s memory. It uses hard drive space as extra RAM when the actual RAM is full. Although it’s useful, sometimes you might want to turn it off or remove it. For example, if your computer has a lot of RAM or you need to save space on your disk. This article will show you how to turn off or get rid of a swap file on Ubuntu, step by step. Before you start, make sure you know what might happen if you disable…

GitHub Actions is an automation feature built into GitHub’s platform. It allows you to automate workflows, including software builds, testing, and deployments, right in your repository. As developers, having this functionality at your disposal can streamline your workflow and boost productivity. This article will guide you through the process of getting started with GitHub Actions. What are GitHub Actions? Before we dive into how to set them up, let’s clarify what GitHub Actions are. Essentially, they are tasks that you can automate directly within your GitHub repository. You can create individual tasks, known as “actions”, and combine them to create…

Caching is a key way to make your web server work faster. It helps by saving data that gets asked for a lot, so it doesn’t have to be loaded fresh every time. This speeds up your website and lessens the strain on your server. This article will show you how to set up caching on the Apache HTTP Server. First, let’s learn a bit about Apache and how it handles caching. Understanding Apache Caching Apache HTTP Server, usually just called Apache, is one of the most common web servers around. It’s known for being strong, flexible, and compatible with…

In this tutorial, we will learn how to create code blocks with a copy code button using Prism.js. Prism.js is a lightweight and extensible syntax highlighter, which allows us to beautifully format code snippets on our web pages. The addition of a copy code button will enhance the user experience by enabling users to easily copy the code to their clipboard with just a single click. Step 1: Set Up the HTML Structure Start by creating a new HTML file and setting up the basic structure. We’ll include the necessary stylesheets and scripts to make use of Prism.js and the…

In Java, reading data from an InputStream and converting it into a String can be a common requirement when dealing with various input sources such as files, network sockets, or web APIs. In this article, we will explore different approaches to accomplish this task along with code examples. Method 1: Using BufferedReader and StringBuilder One of the most straightforward ways to read an InputStream into a String is by utilizing the BufferedReader and StringBuilder classes. The BufferedReader provides efficient reading of characters from an InputStream, while the StringBuilder is used to efficiently build the resulting String. Here’s an example that…

File transfers are a fundamental part of our digital world. Whether it’s uploading an image to a social media platform or sending important documents to a cloud-based storage system, the underlying process is a file transfer. This article will introduce a powerful tool that facilitates such transfers: Curl. Specifically, we’ll focus on how to use Curl to send HTTP POST requests, which allow you to upload or “POST” files to servers. What is HTTP POST? In the realm of web-based communication, HTTP methods play a pivotal role. The HTTP POST method is one of these, typically used to send data…

Many developers interact with APIs on a daily basis, and a popular tool for API interactions is cURL, a command-line tool used to transfer data using various network protocols. One of the overlooked features of cURL is the ability to set the User-Agent string. This tutorial aims to illustrate the importance of the User-Agent string and how to set it with cURL to improve API integration. What is a User-Agent String? Before we delve into how to set the User-Agent string using cURL, let’s understand what it is. When a software is acting on behalf of a user, it identifies…

cURL (or “Client for URLs”), is a command-line tool used for transferring data using various network protocols. It’s a powerful tool widely used in scripting languages to connect and communicate with web services. cURL supports a vast variety of protocols including HTTP, HTTPS, FTP, and much more. One common use of cURL is to POST data to a server. In this guide, we’ll delve into how to use cURL to send POST requests, particularly focusing on how to post a request body. This can be done in several ways: from sending simple form data to posting a JSON body. Basic…

Curl is a powerful command-line tool utilized by developers around the world for transferring data with URLs. A versatile tool, Curl supports various protocols, such as HTTP, HTTPS, FTP, and many more. One of the valuable features of Curl is its ability to pass custom headers while making requests. This article aims to delve deep into the process of passing custom headers using Curl, thus helping you to master this skill. Understanding Headers In the world of web development, headers play a significant role. They carry information about the request or the response, or about the object sent in the…

Asynchronous programming is a programming paradigm that allows multiple operations to execute concurrently without blocking the execution thread. It improves the efficiency of programs, particularly those that require input/output (I/O) operations or need to handle multiple tasks simultaneously. In C#, the async/await pattern has become the de facto standard for asynchronous programming, and mastering this pattern is essential for building robust and high-performing applications. Understanding Asynchronous Programming Before we delve into the specifics of async/await, let’s briefly understand what asynchronous programming is all about. Typically, a program executes tasks sequentially. However, some tasks, such as reading a file, accessing a…
