● Ten Brief Lessons on Web Programming                                                                              The project became a book.                                                                                   Same philosophy: pure PHP, JavaScript, HTML, CSS and SQLite. No frameworks, no libraries, no magic. But now with authentication, search, pagination, and a chapter on security.        Ten chapters (we count from zero), three appendices, and a PDF ready to print and bind. Free, open source, GPL-3.0.                                      "There are 10 types of people in the world: those who understand binary, and those who don't."                                                 Which side are you on?                                                                                     https://lnkd.in/dEKuByFZ   

I got a new book. (JavaScript: The Definitive Guide, 7th Edition) Overview ↘️ JavaScript is the programming language of the web and is used by more software developers today than any other programming language. For nearly 25 years this best seller has been the go-to guide for JavaScript programmers. The seventh edition is fully updated to cover the 2020 version of JavaScript, and new chapters cover classes, modules, iterators, generators, Promises, async/await, and metaprogramming. You’ll find illuminating and engaging example code throughout. ↘️ This book is for programmers who want to learn JavaScript and for web developers who want to take their understanding and mastery to the next level. It begins by explaining the JavaScript language itself, in detail, from the bottom up. It then builds on that foundation to cover the web platform and Node.js. Topics include: ☑️ Types, values, variables, expressions, operators, statements, objects, and arrays ☑️ Functions, classes, modules, iterators, generators, Promises, and async/await ☑️ JavaScript’s standard library: data structures, regular expressions, JSON, i18n, etc. ☑️ The web platform: documents, components, graphics, networking, storage, and threads ☑️ Node.js: buffers, files, streams, threads, child processes, web clients, and web servers ☑️ Tools and language extensions that professional JavaScript developers rely on 🖇️ https://lnkd.in/dv5p6U9M #JavaScript #Oreilly #Books

🚗 The Web Development Journey Every great system begins with something simple… and grows into something powerful. 🔹 HTML — the foundation, the raw structure 🔹 CSS — the personality, the design that brings beauty 🔹 JavaScript — the spark, adding life and interaction 🔹 Node.js — the engine behind the scenes 🔹 MongoDB / Python — the brain, managing data and logic at scale Step by step, layer by layer… what starts as a basic skeleton transforms into a complete, intelligent system. ✨ The real lesson? Big things aren’t built overnight. They’re built by mastering the basics, one step at a time. Stay patient. Keep building. Keep learning. Because one day… you won’t just create websites — you’ll engineer powerful, end-to-end systems. 🚀 #WebDevelopment #JavaScript #NodeJS #MongoDB #Python #FullStack #Developers

Why I Didn’t Build Labs in React? Every time I tell someone our platform is built with PHP + jQuery, I get the same “oh, you poor thing” look. So let me explain the actual decision. Before you pick a frontend stack, ask one question: where does your app live? If your app lives in the browser — Figma, Notion, Linear, Google Docs — then yes, React is the right call. The browser is the source of truth. State, interactions, collaboration, undo history — all of it happens client-side. The server is mostly a sync target. Labs doesn’t live in the browser. Labs lives on the server. The source of truth is MongoDB. The container orchestration is Python. The session lives in PHP. The VPN tunnels are on the host. The real-time messaging runs through RabbitMQ. Everything that matters happens server-side — the browser is just a window into it. In that world, what does React actually buy me? A build step. A second routing layer. A state library that duplicates what my session already knows. Hydration bugs. Auth tokens instead of a cookie. 200+ dialog endpoints rewritten from “render HTML” to “return JSON and re-render it client-side.” SSR to get SEO back. A client-side privilege gate that mirrors the server-side one. More moving parts, same product. PHP is native to the web. A request comes in, HTML goes out. That’s the protocol. One developer can trace a click from .htaccess to MongoDB in five minutes. New feature? Three files. No context switch between two languages, two routers, and two state models. React isn’t wrong. It’s a tool. It solves a real problem — apps where the browser is the source of truth. Using it for server-truth apps is like using a forklift to move a coffee cup: impressive, unnecessary, and someone’s probably going to get hurt. If I were starting Labs today? Same stack. Maybe PHP + htmx to sharpen the edges. Pick the tool for where your app lives — not for where the Internet says it should live.

Just like opening the door, Django web framework gives access. But before that, Happy Easter Monday. I am believing that you have make out time to enjoy yourself and make good use of the holiday. Perhaps in you location you do not have holiday don't worry your time will soon come. I have been away for some time. Really, I have been working on a number of projects offline which actually kept me away all these while, But I want to really appreciate every one of you who make out time to check on me. I am overwhelmed by such a wonderful sense of belonging. Indeed, I am so pleased to have you as my trip Sharing today is unlocking the power of Django API with DRF. This sound interesting right? One of the ways to have a modern web app built is using Django. Using this framework is an easy way to have a seamless connection with both backend interacting with frontend. This results in a fantastic UX. The Django REST framework DRF is the answer to making an appealing and powerful interaction. You can quickly build flexible API that form a bridge, which allows a smooth data exchange framework with a cutting- edge dynamic user experience. Whether your work require creating a responsive web Application or wishing to integrate a third-party service, Python makes it easier to manage data and handle request authentication. How do you leverage DRF to take your Django project to the next level? Let me know which tool you use in handling data request from the backend how effective it is? #pythonprogramming #Djangowebframework #Datarequest #authentication

SOLID is not five rules to memorise. It is five questions to ask every time you write a PHP class. Here is what each one actually means in practice. 🏗️ Every PHP developer has heard of SOLID. Very few can explain what it looks like in real code without reaching for a textbook definition. Here is each principle as a question you ask while writing: S — Single Responsibility: "Does this class do exactly one thing?" // ❌ Wrong — one class handling too much class Order { public function calculate() { } public function saveToDatabase() { } public function sendConfirmationEmail() { } } // ✅ Right — one responsibility per class class OrderCalculator { public function calculate() { } } class OrderRepository { public function save() { } } class OrderMailer { public function sendConfirmation() { } } O — Open/Closed: "Can I extend this without editing it?" Add new behaviour by extending a class, not by modifying it. Once a class is tested and deployed, its internals should be closed to change. L — Liskov Substitution: "Can I swap a child class in without breaking anything?" If CsvExporter extends Exporter, every place that uses Exporter must work identically with CsvExporter. I — Interface Segregation: "Am I forcing classes to implement methods they don't need?" Many small, specific interfaces beat one large general one. D — Dependency Inversion: "Am I depending on abstractions, not concrete classes?" // ❌ Tightly coupled — hard to test, hard to swap class ReportGenerator { private MySQLDatabase $db; // concrete class } // ✅ Loosely coupled — depends on an interface class ReportGenerator { public function __construct( private DatabaseInterface $db ) { } } SOLID is not about perfection on the first pass. It is about asking these five questions every time a class starts to feel heavy, slow to test, or painful to change.

Imagine you want to update a codebase you have not touched in 8 years. In a language you have not seen for 8 years. With a framework you have not used in 8 years. Sounds like a recipe for disaster? It took me about two hours. And this is exactly why I love Ruby on Rails so much. I’ve built web apps with PHP, Java, Clojure, Python, TypeScript, and even Haskell. Step away from most ecosystems for that long, and you come back to an entirely different world. You have to relearn the tooling from scratch, plus figure out which of the ten competing libraries is the current standard. With Rails, it’s completely different. I learned it in my first year of university in 2012, and coming back to it, I realized nothing has changed. In the best possible way. I just jumped back in and was back at home. Of course, Rails has improved over the years: Hotwire and Stimulus replaced the Turbo and jQuery mess and lets me write even less JavaScript code. Real-time reloads just work, but the best thing is that what worked 14 years ago still works now. The gems are mostly the same. The concepts are the same. The ideas just modernized. The default setup is great, and for almost everything, there is one accepted way to do it. This means I can spend my time actually developing features instead of fine-tuning my development environment. And if I get busy with other things and step away for a few years, I know I can pick right back up where I left off without relearning everything. If you haven’t tried Rails and you are starting a new web project, give it a chance. It’s worth it.

🔄 How MVC Works in Laravel (Conceptual Flow Diagram) Separates code into 3 parts for clean & scalable applications. 👉 Many beginners learn Laravel… but still can’t clearly explain how MVC actually works behind the scenes. They can write code. But when asked about the flow, they get stuck. That’s exactly where real developer understanding begins 👇 🧠 Simple Understanding • Model → Data Logic (Eloquent Model, e.g., Product) • View → UI/Blade (e.g., products.blade.php) • Controller → Logic/Connector (e.g., ProductController) 📊 Complete Flow (Step-by-Step): User Request → /products Router → routes/web.php handles the request Controller → ProductController takes control Controller calls Model → interacts with Eloquent Model Model queries Database → (MySQL / MariaDB) Data returns → Controller passes it to Blade View renders response → User sees the final HTML output 💡 Why this matters? When you truly understand this flow: ✔ Clean, structured code ✔ Smaller and maintainable controllers ✔ Scalable applications without complexity 🚀 Pro Tip: Don’t just learn Laravel syntax. Understand the FLOW — and you’ll start thinking like a developer who designs systems. #Laravel #PHP #WebDevelopment #MVC #Backend #SoftwareArchitecture #Coding #Developers #LaravelTips
