Webassembly: Near-Native Performance for Web Applications

stp2y0 CommentsNewscoding, community, development, engineering, frontend, inclusive, performance, software, webassembly, webdev

I was working on a web development project, building a 3D visualizer. This project required a lot of calculations and data processing. I used JavaScript, my go-to language for web development. At first, everything went well. But as I added more features, the website started to slow down. The rendering times increased, and the animations became choppy. It was clear that JavaScript alone wasn't enough for this project. It was slow because JavaScript is an interpreted language and runs on a single thread, meaning it can only do one thing at a time. These performance issues were a big problem,…

Stacks, Data Structures

stp2y0 CommentsNewscoding, community, datastructures, development, dsa, engineering, inclusive, software

Stacks A stack is a fundamental data structure in computer science that operates on a Last In, First Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. Stacks are analogous to a pile of plates where you can only add or remove the top plate. This simplicity and the constraint on how elements are added and removed make stacks particularly useful for certain types of problems and algorithms. Basic Concepts of Stacks Push Operation: This operation adds an element to the top of the stack. If the stack is…

Linked List, Data Structures

stp2y0 CommentsNewscoding, community, datastructures, development, dsa, engineering, inclusive, software

Linked List A linked list is a fundamental data structure used in computer science to organize and store data efficiently. Unlike arrays, linked lists consist of nodes, where each node contains data and a reference (or link) to the next node in the sequence. This structure allows for dynamic memory allocation and efficient insertions and deletions, making linked lists highly versatile and useful for various applications. Comparison with Arrays Linked lists and arrays are both used to store collections of elements, but they have key differences that affect their performance and usage: Memory Allocation: Arrays: Use contiguous memory allocation.

Have you ever been confused between an error and an exception? We often tend to use these words interchangeably. Well, they are not the same, since they have nuanced differences. Let us understand these differences with examples. Error An error usually refers to a condition that hinders a program's normal execution. It can be due to issues like: 1. Syntax Errors Errors which occurs when we have mistakes in our code that prevents the compiler from parsing our program correctly. // Syntax error example: function greet() { console.log("Hello world!"; // SyntaxError: missing ) after argument list } Enter fullscreen mode…

What is codewars? Codewars is a social network of programmers who get together to challenge each other to solve code challenges. Codewars is one of the best websites for practicing algorithms and solving Katas. Katas? Yes, as in Karate. What are katas in codewars? In the spirit of martial arts, more specifically Karate, these code problems are called katas. The katas are divided, ascendingly, according to their difficulty. There are katas from 8th kyu to 1st kyu, with 1st kyu being the most difficult type of kata of all. There are katas on many, many topics: algorithm development, efficiency, regex,…

Creating In-Video Search

stp2y0 CommentsNewsai, coding, community, datascience, development, engineering, inclusive, machinelearning, software, tutorial

In-video search is ability to search for a specific content within a video. This can include searching for particular words spoken, objects shown or description of a scene. With the current advancement in transformers the process of in-video search have become more accurate and fairly simple. Although most of the transformers doesn’t have a joint embedding space for multiple modalities but there are few models like Meta’s ImageBind that a joint embedding space between text, image, audio, depth, thermal and IMU, or OpenAI’s CLiP model have joint embedding space between text and image. We can use these models to create…
