Linux is a free and open-source operating system that is widely used in modern computing systems. It has a rich set of features that make it one of most popular operating systems in world. One such feature is use of swap space. Swap space is a part of Linux file system that is used to temporarily store data when computer's RAM (Random Access Memory) is full. In this article, we will discuss use of swap space in modern Linux systems, its benefits, and how to configure it. What is Swap Space? Swap space is a designated area on a hard ... Read More
Introduction When it comes to programming, there are numerous occasions when we need to execute multiple commands and take input or output from a single command. In such cases, sending output of a command to multiple commands becomes an essential task. Sending stdout to multiple commands is one of most frequently used techniques in programming. In this article, we will discuss what stdout is and how we can send it to multiple commands with examples. So, let’s get started. What is stdout? Stdout (Standard Output) is a default stream in Unix-like operating systems, which is used to display output of ... Read More
Introduction Teaching Learning Based Optimization (TLBO) is based on the relationship between a teacher and the learners in a class. In a particular class, a teacher imparts knowledge to the students through his/her hard work. The students or learners then interact with each other among themselves and improve their knowledge. Let us explore more about Teacher Learning Based Optimization through this article. What is TLBO? Let us consider a population p (particularly a class) and the number of learners l in the class. There may be decisive variables (subjects from which learners gain knowledge) for the optimization problem. Two modes ... Read More
Introduction Bash scripting is a powerful way of automating repetitive tasks and executing complex commands with a single script. With increasing popularity of web-based technologies, it's now possible to execute Bash scripts directly from a URL. This opens up a whole new world of possibilities for web developers and system administrators. In this article, we'll explore how to execute Bash scripts directly from a URL and provide some examples to help you get started. What is Bash Scripting? Bash scripting is a type of scripting language that is commonly used on Unix-based systems such as Linux and macOS. Bash stands ... Read More
Introduction The Particle Swarm Optimization algorithm is inspired by nature and is based on the social behavior of birds in a flock or the behavior of fish and is a population-based algorithm for search. It is a simulation to discover the pattern in which birds fly and their formations and grouping during flying activity. Particle Swarm Optimization Algorithm In the PSO Algorithm, each individual is considered to be a particle in some high-dimensional search space. Inspired by the social and psychological behavior of people, which they tend to copy from other people's success, similar changes are made to the particles ... Read More
When working with datasets, it's important to understand characteristics of data. One of most fundamental aspects of a dataset is its central tendency - point around which data tends to cluster. This can be quantified in a number of ways, including minimum, maximum, median, and mean. In this article, we'll explore these different measures of central tendency and show you how to calculate them using a variety of programming languages. What is Minimum of a Dataset? The minimum of a dataset is smallest value in set. This value is useful for understanding lower bounds of data and can help identify ... Read More
Introduction Image Segmentation is the process of partitioning an image into multiple regions based on the characteristics of the pixels in the original image. Clustering is a technique to group similar entities and label them. Thus, for image segmentation using clustering, we can cluster similar pixels using a clustering algorithm and group a particular cluster pixel as a single segment. Thus, let's explore more image segmentation using clustering, Image Segmentation The process of image segmentation by clustering can be carried out using two methods. Agglomerative clustering Divisive clustering In Agglomerative clustering, we label a pixel to a close ... Read More
Introduction RPA stands for Robotic Process Automation. An RPA developer is a person who designs, maintains, builds, and implements RPA systems. In an organization, an RPA developer has the role to create optimized workflow processes and work cross-functionally with operations and business analysts. Scope of an RPA Developer Today the world is moving towards automation where organizations maximum repetitive processes to be automated as much as possible. Thus the demand for highly skilled RPA professionals has gained pace. With the right skill set, RPA developers can fill the in the respective domains. An RPA developer is essentially a software developer ... Read More
Introduction Exploratory Data Analysis (EDA) is the process of summarization of a dataset by analyzing it. It is used to investigate a dataset and lay down its characteristics. EDA is a fundamental process in many Data Science or Analysis tasks. Different types of Exploratory Data Analysis There are broadly two categories of EDA Univariate Exploratory Data Analysis – In Univariate Data Analysis we use one variable or feature to determine the characteristics of the dataset. We derive the relationships and distribution of data concerning only one feature or variable. In this category, we have the liberty to use either ... Read More
Docker is a widely popular open-source tool that simplifies process of creating, deploying, and running applications within containers. Alpine, on other hand, is a lightweight Linux distribution that is optimized for Docker containers, making it a perfect choice for those who want to keep their images small and efficient. In this article, we will explore how to start a shell in Alpine Docker container, and provide several examples that will demonstrate its usage and benefits. What is a Shell in a Docker Container? Before we dive into how to start a shell in Alpine Docker container, it is essential to ... Read More
