HTML elements are more than just tags — they carry extra information through attributes. Attributes define how an element behaves or appears. You’ve seen them everywhere: Here’s what each attribute does: Attributes like these give meaning to elements and guide how they behave in the browser. With JavaScript, we can go a step further — […]

The JavaScript bind() method creates a new function that has its this keyword set to a specific value. This helps control what this refers to when the function runs. The goal of this article is to show you how to use the bind() method to fix the value of this in functions. This is especially

When you write CSS for a web page, you can give styles to elements in many different ways. You can use classes, IDs, tags, or even add styles directly in HTML. Sometimes, more than one rule might apply to the same element. When that happens, the browser has to choose which style to use. It

JavaScript timers let us schedule code to run after a certain amount of time. They’re useful for delays, repeated tasks, and adding a bit of life to our code—like waiting before showing a message or running something every few seconds. In this article, we’ll focus on how to use two built-in JavaScript functions: setTimeout and

Process management is an important part of working with operating systems, and Python makes it easy using the psutil library. This powerful tool lets you access and control system processes directly by their Process IDs, or PIDs. With psutil, you can find running processes, read detailed information about them, and even manage their state—like suspending,

When working with multiple processes in Python, sometimes one process needs to tell others to start or stop doing something. This is called signaling. The multiprocessing.Event is a simple tool that lets one process send a signal, and other processes wait for that signal before continuing. In this article, you will learn how to create

When working with multiple processes in Python, it’s sometimes important to make sure they all reach a certain point before moving on. This is where multiprocessing.Barrier comes in. A barrier allows you to pause several processes at the same spot until all of them have arrived. Only when everyone is ready do they all proceed

Inter-Process Communication (IPC) is how different running Python processes share information with each other. When processes need to work together quickly, sharing data directly in memory is very useful. RawArray from Python’s multiprocessing.sharedctypes module provides a way to create fixed-size arrays in shared memory. Unlike other shared objects, RawArray does not use locks, so it

Inter-Process Communication (IPC) allows different processes in a program to share information and work together. When processes run separately, sharing data quickly and simply is important for smooth communication. One way to do this in Python is by using shared memory. RawValue is a tool in Python’s multiprocessing.sharedctypes module that lets you share basic data

Inter-Process Communication (IPC) is how different processes in a program share data with each other. In Python, processes don’t share memory space by default, so when they need to work with the same data—like numbers in a list—we need a safe way to do that. That’s where multiprocessing.Array comes in. It creates a shared array
