SVG Diagrams and Parametric Generators: Testing 358 Questions Across 200 Seeds
"Calculate the hypotenuse BC of the right triangle at A. AB = 12 cm, AC = 9 cm, BC = ?" The student reads the question, looks at the diagram… and the diagram says AB = 3 cm. Different triangle. The values in the question are randomly generated, but the diagram is static. This kind of bug doesn't crash anything — it just makes an educational tool unusable.Radar College is a quiz platform for French middle school exams.

Incident Post-Mortem: Debunking the Low-Velocity Trap in Modern Cross-Border Data Discovery 🌐
Classification: Operational Efficiency ReportCore Problem: Cumulative team friction during cross-border multimedia routing and vertical asset exploration.During our Q2 internal performance audit, we uncovered a hidden infrastructure bottleneck that was silently burning through our team's operational velocity. While analyzing the developer动线 (interaction footprints) across decentralized technical repositories and international media pools, we discovered that over 55% of our static bookmark arrays
I Recreated the Panini World Cup Sticker Album as a Free Web App
Remember ripping open Panini sticker packs as a kid?That rush of discovering which players you got. The heartbreak of yet another duplicate. Playground negotiations to complete your album.The FIFA World Cup 2026™ is coming — 48 nations, 3 host countries, the biggest tournament in history. So I asked myself: what if the entire Panini collecting experience lived online?Free. Social. Playable from any phone or laptop.So I built it. 🚀 👉 Try it live: ghcp-panini.onrender.com What You Get📦 3
The 0$ AI Achitecture Stack (2026)
AI is getting expensive.Not only because of model APIs, GPU bills, vector databases, cloud platforms, observability tools, and managed services, but also because we often start building with the most expensive architecture before we understand the problem.But here is the good news: today, a software engineer can learn, prototype, and even launch serious AI systems with a $0 software stack.Of course, “$0” does not mean magic.You still pay for hardware, electricity, domains, bandwidth, production
React State Management: Stop Over-Rendering Your Components!
In the React ecosystem, one of the most common pitfalls developers encounter is the excessive and unnecessary use of useState. As React developers, we often fall into the trap of treating state as the default solution for every piece of data, leading to performance bottlenecks and difficult-to-debug codebases.In this article, we will explore how state truly works and how adopting a modular approach can lead to cleaner, more maintainable code.Understanding State Updates: The Performance CostIn Re
Understanding The "Why" Behind Software Design: Introduction
✨ Why Software Design MattersIf you've been developing software for a while, you've probably come across terms like:Object-Oriented Programming (OOP)EncapsulationAbstractionInheritancePolymorphismSOLID PrinciplesDependency InjectionDesign PatternsThere are countless articles, videos, and courses explaining these concepts.Still, there are plenty of developers, including me, who learn those concepts and forget them very quickly.We memorize definitions.We learn syntax.We understand enough to
How to Copy All Chrome Tab URLs as Markdown, JSON, or CSV — Free Extension
Chrome has never had a built-in way to save or export your open tabs. If you've ever wanted to snapshot a research session, share a list of links, or pipe tab URLs into a script or AI assistant — you had to do it manually, one by one.I built Safe Tab URL Lister to fix that. One click, four formats, zero tracking. What it doesClick the toolbar icon, pick a format, click Copy. That's the entire workflow. 4 output formatsPlain text — one URL per linehttps://github.comhttps://news.ycombina
I rewrote 3 useEffects to use() in React 19. Here's the one I shouldn't have.
The first time use() clicked for me, I closed the tab on the React docs and immediately went through my codebase looking for useEffect calls to delete.Three rewrites later, I reverted one. Here's what I learned about when use() is the right tool — and when reaching for it is the wrong instinct. The setupuse() in React 19 lets you read the value of a promise inside a component. The component suspends while the promise resolves, and React handles the rest:function UserCard({ userPromise }: {
How I Built 5 Operational Reporting Generators Using Next.js
Most reporting workflows still rely on spreadsheets, Word documents and manually formatted PDFs.Coming from an operations and industrial background, I noticed that many supervisors spend more time formatting reports than actually documenting work completed during a shift.Daily reports, maintenance reports and handover reports are often created from scratch every day, even though the structure is usually very similar.I wanted to see if a collection of simple web tools could make that process easi
What Is the MERN Stack? A Beginner-Friendly Introduction
If you're interested in web development, you've probably come across the term MERN Stack.MERN is a full-stack JavaScript technology stack made up of:MongoDBExpress.jsReactNode.jsTogether, these technologies allow developers to build complete web applications using JavaScript from frontend to backend.Why do so many developers choose MERN?✅ One programming language across the entire stack✅ React for modern user interfaces✅ Node.js for backend development✅ MongoDB for flexible data storage✅ Excelle
How I Built a Browser-Based File Compression Tool for India Using Canvas API and pdf-lib — No Backend Needed
I built ResizeKB — a free image and PDF resizer built specifically for Indian users. 25+ tools. Zero server uploads. Pure HTML, CSS, JavaScript. Here's how and why.The ProblemEvery Indian applying for government jobs, exams, or bank accounts hits the same wall — portals with strict KB limits rejecting documents.UPSC wants photo under 300KB. SSC wants under 50KB. Banks need Aadhaar PDF under 500KB. Every portal is different. Every rejection wastes someone's time and opportunity.Most people have n
3 TypeScript patterns I keep stealing from open-source codebases
Every few months I find a TypeScript pattern in someone's open-source repo that I instantly bring back to my own code. It's the cheapest form of getting better — read code that's been read by hundreds of contributors and find the patterns that survived.Here are three I keep reaching for in 2026. 1. satisfies for catch-typos-at-compile-time configsYou know the routine — a config object that holds, say, all your route paths, or all your event names. You want autocomplete when you reference on
React vs. Angular: Which One Should You Use for Your Next Web Project?
If you're choosing between React and Angular right now, the honest answer is: it depends on what you're actually building, not on which one has more GitHub stars.I've worked on projects that used both, and I've seen teams pick the wrong tool because they followed hype instead of requirements. This isn't a "React always wins" or "Angular is enterprise-grade therefore serious" post. It's a breakdown of when each one actually makes sense.

Cut Network Latency: Optimize Next.js with Brotli ⚡
The Overlooked Bandwidth TaxWhen optimization is discussed in modern frontend development, developers frequently focus on component code-splitting or caching engines. While these are critical paths, teams often neglect the literal size of the text payloads traveling across the network. Every time a user visits a data-dense dashboard, your Next.js server dispatches large pieces of server-side rendered HTML, inline JSON hydration scripts, and asset bundles. If these payloads travel raw and uncompr

Next.js Dark Mode Without the Flash (Tailwind v4)
Every dark mode implementation has the same enemy: the flash.The page renders in light mode, then instantly switches to dark. It happens because JavaScript applies the CSS class after the HTML is already painted -- and by then it's too late. Why It HappensBrowsers paint HTML before JavaScript runs. By the time your JS reads localStorage and adds dark to <html>, the first frame is already done.The only real fix is a blocking inline script in <head> that runs before any rendering.
