Importance of JPG Images

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

What Are JPG Images? JPG, also known as JPEG (Joint Photographic Experts Group), is a widely-used image format that employs lossy compression to reduce file size while maintaining acceptable image quality. Introduced in 1992, the JPG format has become the standard for digital photography and web images due to its balance of quality and file size. Characteristics of JPG Images - Lossy Compression: JPG images use a compression method that reduces file size by discarding some of the image data, which can result in a loss of quality, especially at higher compression levels.- Color Range: JPG supports 24-bit color, which…

What are the Benefits of Using ECMAScript Classes Over Traditional Prototype-Based Inheritance?

stp2y0 CommentsNewscoding, community, development, ecmascript, engineering, inclusive, javascript, programming, software, webdev

JavaScript has long utilized prototype-based inheritance as a core mechanism to build reusable code. This traditional approach of leveraging prototypes to define methods and properties that JavaScript objects can inherit has served developers well over the years by offering flexibility and dynamic features that help drive web innovation. But with ECMAScript 2015, also known as ES6, JavaScript embraced a new syntactic feature—classes. These ECMAScript classes provide a much clearer and more familiar syntax for creating objects and dealing with inheritance, drawing close parallels with classical object-oriented programming languages. Understanding Prototype-Based Inheritance In JavaScript, objects utilize prototype-based inheritance, a form of…

#babylonjs Browser MMORPG #indiegamedev Ep21 – Spatial Hash Grid Area of Interest

stp2y0 CommentsNewsbabylonjs, coding, community, development, devlog, engineering, inclusive, indiegamedev, mmorpg, software

HelloI'm working on POC (prove of concept) implementation of monsters system. I managed to achieve first milestone which is loading entities into engine.And finally i have occasion to show You how my hash grid area of interest is working.Engine is refreshing area of interest data each second and it sends info to the clients to show/remove entity. There're two visibility ranges. First is lower (eg 50 units) it describes distance below which entity should be visible and second visibility range (eg 100 units) is bigger and it's use to hide entities. This way I'm avoiding sending create/remove entity command when…

Abstraction is a Principle of OOP used to hide unnecessary information and display only necessary information.For example you can start a car by turning the key or pressing the start button.You don't need to know how the engine is getting started. Source link lol

RxJs and Redux-Observable

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, observable, redux, rxjs, software, webdev

Redux-Observable is a middleware for Redux that uses RxJS to handle asynchronous actions. It offers an alternative to redux-thunk and redux-saga, allowing you to work with async actions using observables. Understanding the Observer Pattern Before diving into RxJS and Redux-Observable, let's revisit the Observer Pattern. In this pattern, an "Observable" object maintains a list of "Observers". When the Observable's state changes, it notifies all its Observers. document.addEventListener("click", (event) => { console.log("Element clicked:", event); }); Enter fullscreen mode Exit fullscreen mode In this example, addEventListener makes the document an Observable, and the callback function is the Observer. Diving into RxJS RxJS…

There are different WebRTC architecture available today, these are SFU, MCU and P2P, selecting one depends on many factors these include Network Conditions Bandwidth availability If participants have good quality bandwidth then SFU and peer to peer calling will work for them If the participants do not have good quality bandwidth and there are a lot of participants than going with a MCU would be a good idead Latency Sensitivity If the situation requires low latency then going with an SFU and/ or peer to peer is a good idea If there is a tolerance for latency and latency is…

The Right Way to Clone Nested Object/Array (Deep Clone) in Javascript

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, frontend, inclusive, javascript, software, webdev

As you might know, Javascript uses pass-by-reference when passing an object, array, or function to a new variable. When you pass an object, array, or function to a new variable, a reference (memory address) to the object is passed. Any modification to the object's properties in the new variable will be reflected in the original object since they both point to the same memory location. const original = { name: 'Alice' }; const newVariable = original; newVariable.name = 'Bob'; console.log(original); // { name: 'Bob' }; Enter fullscreen mode Exit fullscreen mode To solve this issue we can use Object.assign() or…

CAPTCHA

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

Introduction This is what a Captcha test would be best suited for. What is CAPTCHA? According to the Official CAPTCHA website, CAPTCHA is a "program that protects websites against bots by generating and grading tests that humans can pass but current computer programs cannot." This means that the intended purpose of the CAPTCHA tests is to determine if a "user" is truly a human or a component of some form of automated program (bot). Short for Completely Automated Public Turing test to tell Computers and Humans Apart, the full phrase that the acronym represents makes it much more apparent as…
