Web Workers for Multithreading in JavaScript

Web Workers are a feature of the Web API that allows JavaScript code to run in the background on a separate thread, improving performance by offloading resource-intensive tasks from the main thread.
Web Workers operate in a different execution context and can communicate with the main thread via messages. They do not have access to the DOM, window, or document objects.
To use Web Workers, create a separate JavaScript file containing the code to be executed in the background. Initialize the worker in the main thread, send and receive data through messages, and terminate the worker when no longer needed.
Web Workers offer improved performance, better user experience, and scalability by preventing the main thread from being blocked, allowing the UI to remain responsive even during intensive operations.

Tree data structure tutorial 14. Fenwick trees and implementation

Fenwick tree is an efficient data structure for range sum queries and range updates which takes advantage of the fact that all numbers can be represented by 2^n.
We can calculate the range in power of 2.
The Fenwick tree algorithm pre-computes and stores sums for specified ranges such as [0, r], where r is a power of two or less.
It requires less space than the segment tree and takes O(n log n) time to build, O(log n) time for updates, and O(log n) time to compute the range sum.
We can use Fenwick tree to compute the sum for the range [ 0 – 3].
We can update the array elements by starting from the index and then moving rightwards to update the next ranges.
We can achieve this by binary representation i.e., go to the index and add the last set bit to know the next index to be updated.
The article explains the concept of Fenwick tree with a step-by-step explanation on how to implement range sum and range update queries and shows a C code implementation.
Fenwick tree is a useful and efficient data structure that can be applied in many algorithmic problems involving range queries and update operations.
It is faster than simple brute force approach as well as the Segment Tree data structure.

Tree data structure tutorial 13. Lazy propagation of segment trees with example

Lazy propagation is a technique used in segment trees to optimize updates on a large amount of data.
It reduces the number of unnecessary updates by postponing them until necessary.
The need for lazy propagation arises when there are frequent update queries on the segment tree.
Lazy propagation helps improve performance by updating values only when required.

The Easiest Way to Package Your Python Files(Turn to .exe Files)

Python does not produce executable files during compilation, but a program can automate the packaging process using the pyinstaller library.
To use the automated packaging tool, the prerequisite step is to install conda for creating and managing virtual environments.
The tool supports packaging in Windows environments specifically for creating .exe files.
The GitHub Repository provides two tools: EasyPackager and PeasyPackager, where EasyPackager is recommended for simpler packaging needs.

How to write same test case for both Desktop and Mobile Web — CrossViewPort Automation

The approach of writing test cases for both Desktop and Mobile Web involves duplicating locators in different classes.
To overcome this, we can use abstract page classes to handle initialization and differentiate between Web and Mobile views.
Common locators and methods can be kept in the abstract page class, while specific ones are stored in their respective classes.
From the test case class, communication should happen only through the abstract class to ensure seamless execution.
