Amazon Web Services (AWS) offers various services like EC2, S3, AWS Lambda, and Amazon SageMaker. Companies use these Amazon services to store their databases and deploy their models. In this article, we will discuss Simple Storage Service (S3) and explain how to upload and download a file from Amazon S3. AWS S3 Simple Storage Service (S3) is used to store various files on the cloud. It is secure, simple, and cost-effective. In S3, there are buckets to store files such as images, folders, videos, and audio files. We can store, download, and upload files in different ways on S3. ... Read More
In Python the os module provides two methods for creating a directory they are os.mkdir() and os.makedirs(), we can create a Single directory by using os.mkdir() method and by using the os.makedirs() method we can create Subdirectories. To use those two methods, we need to include the os module, which allows us to interact with the operating system. The two common approaches to creating a directory using Python are as follows. Using 'os.mkdir()' Method: To Create a Single Directory ... Read More
There are several benefits to using operating system-based virtualization. You can run multiple operating systems on the same physical hardware. This can be useful for testing different operating systems, running legacy applications, or saving space on your computer. Another advantage is that it can improve performance. By isolating each operating system from others, virtualization software can prevent conflicts and improve overall system performance. It creates a layer of abstraction between the hardware and the operating systems. The virtualization software is installed on the host operating system. It manages this layer of abstraction and allows guest operating systems to access ... Read More
In Python we can use FTP (File Transfer Protocol) by importing the ftplib module, it will provide a simple interface to access FTP servers to retrieve files and process them locally. ftplib module allows us to write Python programs that perform a variety of automated FTP tasks. Objectives of FTP The objectives of FTP are as follows FTP provides file sharing. FTP helps us to encourage the use of remote computers. FTP is used to transfer the data reliably and efficiently. Some Common tasks we can perform using FTP in Python by utilizing the 'ftplib' module are as follows: ... Read More
The dutree is an open-source and free command line tool in Linux that lets you analyze disk usage and display the output in a colored format. This command combines two well-known Linux commands, the durep (generates disk usage report) and the tree (lists the contents of a directory in tree format) commands, and their attributes, written in the Rust language. Whenever you use this command to determine disk usage, it displays the result in a tree-like format. The dutree command is mainly used to see which directories and files take up the most space on the hard disk and lists ... Read More
To convert HH:MM:SS to seconds with JavaScript, we will be using simple arithmetic operations like mltiplication and addition. We will be understanding this conversion with two example codes and their stepwise explanation. In this article, we are given a time in HH:MM:SS format and our task is to convert HH:MM:SS to seconds with JavaScript. Steps to Convert HH:MM:SS to Seconds We have used two div to display the time and the result in seconds. The time variable stores the time in HH:MM:SS format. Then we have used split() function to ... Read More
In this article, we will learn how to compute a cuboid's surface area and volume using Java. A cuboid is a three-dimensional object with six faces in a rectangle shape, which means it has sides of different lengths and breadth. The difference between a cube and a cuboid is that a cube has equal length, height, and breadth, whereas these three are not the same in cuboids. Problem Statement Write a program in Java to find a cuboid's surface area and volume. Below is a demonstration of the same − Input Length= 6; Width= 7; Height= 8; Output Volume Of the Cuboid is ...

In this article, we will learn how to display a webpage in JEditorPane using Java. The program will load a specified webpage, and display it within a GUI window. If the connection to the webpage fails, a message will appear indicating the connection issue. This setup can be useful for embedding simple web content within Java applications. Steps to display a webpage in JEditorPaneFollowing are the steps to display a webpage in JEditorPane −We will import the necessary classes from the java.io package and javax.swing package.Create a JEditorPane object to serve as the component that will display the webpage.Use the setPage() ...

A modified version of the PIL called pillow library can be used to generate a text-based CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) in Python Imaging Library. Types of CAPTCHA There are different types of CAPTCHA and some of them are follows below. Text-based CAPTCHA : A sequence of characters is provided with features distorted and random noise to make character recognition difficult. ... Read More
Flexbox is a powerful layout tool that allows us to align items within a container dynamically. However, sometimes you may want a flex item to take up only as much width as its content, rather than stretching to fill the available space within the container. In this article, we’ll go over different techniques to make specific items within a flex container take up only the space needed for their content, without stretching to fill the available space. Approaches to Make Flex Items Take the Content Width Using CSS align-self Property ... Read More
