  JWT এর আদ্যোপান্ত - ডেভেলপারদের জন্য আধুনিক অথেনটিকেশন সমাধান সফটওয়্যার ইঞ্জিনিয়ারিংয়ের জগতে অথেনটিকেশন এবং অথোরাইজেশন নিয়ে কাজ করতে গেলে JSON Web Token (JWT) এর নাম শোনেননি এমন কাউকে খুঁজে পাওয়া দুষ্কর। তবে অনেক সময় আমরা এটি ব্যবহার করলেও এর অভ্যন্তরীণ কার্যপদ্ধতি এবং সিকিউরিটি নিয়ে কিছুটা ধোঁয়াশায় থাকি। আজকের এই আর্টিকেলে আমরা JWT-কে একটি নতুন আঙ্গিকে দেখব—এর গঠন থেকে শুরু করে আধুনিক সিস্টেমে এর প্রয়োজনীয়তা এবং সিকিউরিটি বেস্ট প্র্যাকটিস পর্যন্ত। ১. JWT আসলে কী এবং কেন? JSON Web Token (JWT) হলো একটি ওপেন স্ট্যান্ডার্ড (RFC 7519), যা মূলত দুটি পক্ষের মধ্যে তথ্য আদান-প্রদানের একটি নিরাপদ মাধ্যম। আধুনিক ডিস্ট্রিবিউটেড সিস্টেম বা মাইক্রোসার্ভিস আর্কিটেকচারে এটি অত্যন্ত জনপ্রিয় কারণ এটি Stateless । অর্থাৎ, সার্ভারকে ইউজারের সেশন ডাটাবেসে সেভ করে রাখতে হয় না; টোকেন নিজেই নিজের পরিচয় বহন করে। ২. টোকেনের ব্যবচ্ছেদ: JWT-এর অভ্যন্তরীণ গঠন সাধারণভাবে একটি JWT টোকেন header, payload এবং signature—এই তিনটি অংশের সমন্বয়ে তৈরি হয়। অংশগুলো পরস্পরের থেকে ডট ( . ) দ্বারা পৃথক থাকে এবং প্রতিটি অ...

Tariq's Truth Engine - Research, Write, Reveal, Seamlessly

By Ashiq

  Tariq stared at the screen, a web of interconnected documents splayed across his Midgen AI Freestyle Editor. His exposé on corporate malfeasance was nearing its climax, but one critical piece of information remained elusive: the exact financial leverage Malik ’s shell company held over the city council’s latest zoning decision. He had a dozen leaked emails, three interview transcripts, and a dense financial report, all open as separate documents in the left-side panel. He was drafting a paragraph, trying to connect a vague statement from an email to a specific clause in the zoning document. He typed: "The email from Hassan hinted at undue influence, but the true mechanism lay hidden in the labyrinthine language of the zoning ordinance..." He needed to find that clause, and quickly. Instead of minimizing his current draft, he simply clicked on the 'Zoning Ordinance - Final.pdf' in his document management panel. The PDF instantly appeared in the main editor window. ...

Great Engineers Don’t Just Code — They Communicate and achieve Technical Excellence

  Great Engineers Don’t Just Code — They Communicate and achieve Technical Excellence Introduction Software engineering has been through a profound transformation over the last decade. Especially the last 3 years. Historically, the image of a software engineer was often that of a lone-wolf figure , deeply focused in code and isolated from the broader organizational context. However, as technology has become the central nervous system of modern business, the role of the engineer has evolved from a technical worker to a strategic collaborator. In this contemporary environment, technical proficiency—while foundational—is no longer the sole determinant of professional success. The increasing complexity of software systems and applications in reality made a software engineer's ability to be compared with a huge algorithmic status. What Are Soft Skills in Software Engineering? In the context of software engineering, soft skills refer to the cluster of personality traits, social graces,...

Using Generic in TypeScript about types in the Code

By Ashiq

# Using Generic in TypeScript about types \<T> in the Code ## Question 1: Here what is this <T> means? ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` ## Answer 1: In the code snippet you've provided, `<T>` is a **generic type parameter** in TypeScript. It allows you to write a function that can work with any type of object while still maintaining that object's specific type information. When you use the function `addID`, you can pass in an object of any type, and TypeScript will understand that the returned object will be of the same type as the input, plus the additional `ID` property. Here's a breakdown of how it works: ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` - `<T>`: Declares a generic type `T`. - `(obj: T)`: Indicates that the function takes an argument `obj` of type `T`....
