What is PHP ? Popular server-side scripting language PHP (Hypertext Preprocessor) is mostly used for web development. For building dynamic web pages and applications, it offers a dynamic and interactive environment. Dynamic content can be produced on the server using PHP code that is inserted in HTML markup and performed on the client's web browser. PHP provides a wide range of features, including database connectivity, session management, form handling, and file manipulation, thanks to its rich libraries and frameworks. It is renowned for being straightforward, adaptable, and widely used, making it a top option for creating dynamic websites and web ... Read More

With procinfo, you can quickly and easily monitor important metrics like CPU usage, memory usage, and process information, all from the comfort of your terminal. Whether you're trying to diagnose a performance issue or simply want to keep tabs on your system's health, procinfo is an essential tool for any Linux user or ... Read More
Dictionaries are among the most powerful data structures in Python programming languages. This is a data structure consisting of key-value pairs. It has several advantages; for example, accessing the values occurs in O(1) time complexity, it is memory efficient, easy to update, delete and iterate, and offers many built functions for quick operations. Problem Associated When Lists Are Used Directly We are focusing on this topic because there is a problem associated with when we try to make the lists as the key. Lists are mutable data types in Python. Hence, we can delete, update, and append values inside the ... Read More
In this tutorial, we will delve into the concept of sending signals to processes in shell scripting, equipping you with the knowledge and skills to effectively control and interact with processes. Signals serve as a means of communication between processes, enabling them to convey specific instructions or handle various events. Our focus will be on using shell scripts to send signals to processes. In the following sections of this article, we will cover different aspects of sending signals to processes, starting with a solid understanding of signals and their usage. We will then dive into various methods of sending signals ... Read More
PyTorch is a popular open-source machine-learning library. Data scientists, researchers, and developers use this library widely to develop AI/ML products. One of the most important features of PyTorch is the Data Loader class. This class helps to load and batch the data for neural network training efficiently. This article will teach us how to use the Data Loader in PyTorch. Use Data Loader In PyTorch We can follow the following basic rules to perform the Data Loading operation in Python using the PyTorch library − Data Preparation − Create a custom Random Dataset class that generates a random dataset ...

What is Static Method? In PHP, a static method is a method that belongs to the class itself rather than an instance (object) of the class. It can be accessed directly using the class name, without the need to create an instance of the class. Example Output 25 27 In the example above, we have a MathUtility class with two static methods: square() and cube(). These methods perform simple mathematical operations and return the result. Since the methods are static, we can directly access them using the class name followed by the :: operator, without ... Read More
