LunuBet Online Casino: What Swiss Players Should Know Before Signing Up
The online casino market in Switzerland has grown crowded, and telling a solid platform from an average one isn't always easy. Flashy welcome bonuses grab attention, but the real quality of a casino shows in the details: how transparent its terms are, how clearly limits are displayed, and how reliably it pays out. This short guide uses LunuBet online casino as a practical example. Clear bonus conditionsA big bonus means little if the wagering requirements are buried in fine print. Trustwort
Service Workers Explained Like You're Building Your First PWA
Spend any real time poking around Progressive Web Apps (PWAs), and sooner or later you’ll run headfirst into Service Workers.The line you’ll hear over and over is that they’re "a proxy between your app and the network."Which is true, and also close to useless if what you’re actually after is why they exist and what they buy you.Here’s the framing that finally made it stick for me:A Service Worker is a programmable layer sitting between your app and the internet, handing you the controls over how
Building an Open Graph / meta-tag previewer: one set of tags, three social cards, and the fallback chain behind them
When someone shares your link, the platform's crawler fetches the page and reads a handful of <meta> tags out of the <head> to build a preview card. There are two overlapping vocabularies — Open Graph (og:*) for Facebook, LinkedIn, Slack and most others, and Twitter Cards (twitter:*) for X — and each platform reads what it wants, falls back when a tag is missing, and truncates differently. I built a previewer that resolves that whole mess live, renders the three real-world cards, and
The LinkedIn profile header, rebuilt: the banner-and-avatar overlap is one negative margin, a white ring, and object-fit
Open LinkedIn, X, Facebook, GitHub or Notion and the top of every profile is the same object: a wide cover photo with a round avatar sitting over its lower edge, then a name, a headline, a place, and a row of actions. It is one of the most copied layouts on the web. I rebuilt it from scratch — editable in place, with swappable photos and a mobile reflow — and the whole recognisable part comes down to about three honest CSS tricks. Here is the anatomy. The overlap is one negative margin plus
Building a full chess engine from scratch: 64 characters and one "is this square attacked?" routine run the whole rulebook
Chess looks like the kind of thing you reach for a library to do. It isn't. When I built a complete, rule-enforcing board in vanilla JavaScript — every piece moving by its true rule, check, castling, en passant, promotion, checkmate and stalemate all enforced — the whole engine came to about 180 lines with no images and no dependencies. The trick is that almost everything falls out of one small board representation and a single "is this square attacked?" routine. Here is how it fits together.
Why I Built My Own GPA Calculator (and How I Handled Multi-Scale Grade Math in JavaScript)
Every finals week in college followed the exact same stressful ritual: sitting in front of a messy spreadsheet at 2 AM, trying to figure out what score I needed on a 30% final exam to keep my 3.5 cumulative GPA. To make matters worse, different courses used different credit weightings, and half of the online tools I tried were either covered in intrusive ads, broken by math edge cases, or locked behind account paywalls just to calculate a target grade.That frustration is why I built GradePoint P
Stop Installing 15 Icon NPM Packages in Every Single Project. Do This Instead.
We’ve all done it. You start a new React, Vue, or Next.js project. You need icons. So what do you do?npm i lucide-reactnpm i @heroicons/reactnpm i react-iconsnpm i @tabler/icons-reactBefore you know it, your node_modules is pushing 2GB, your bundle analyzer looks like a crime scene, and you’re still missing that one specific "shopping-bag-check-outline" icon for your navbar.So you switch tabs to Google, search "free svg icon", land on some ad-infested site, click "Download SVG", drag it into you
React Server Components - The Mental Model Shift
React Server Components are not a performance trick. They are not a simpler way to do SSR. They represent a genuine renegotiation of where computation lives in a React application — and if you approach them as an incremental upgrade, you will architect yourself into corners that are painful to escape.After working through RSC adoption in production Next.js applications, I want to lay out what actually changes at the architectural level: data fetching patterns, bundle composition, state managemen

The Web Speech API will not give you multilingual form filling — here is the pipeline that will
If you run an international website, your form abandonment has a flavor domestic sites never taste: visitors who can read your English form fine but stall when they have to write answers in it — on a phone keyboard, in the wrong layout, with locale habits that fight your validation rules. I build TypelessForm (disclosure), and this failure mode is exactly what we built for, so here is the technical version. Why webkitSpeechRecognition is not the answer (alone)The Web Speech API is a legitim
How to Copy and Sync a Local MongoDB Collection to Atlas
Moving data from a local MongoDB database to Atlas usually means exporting files, importing them again, and repeating the same process when something changes.I wanted to test a simpler way in VisuaLeaf: copy a local collection to MongoDB Atlas and keep the Atlas collection updated automatically.For this example, I used a local visits collection containing seven documents. The documents included ordinary fields, nested objects, arrays, dates, and ObjectIds, so I could also check whether the origi
A Streaming-First UI Framework Built for the AI Era
Most AI products still stream words.But what if an AI model could stream the interface itself?I recently explored Aktion, an ambitious open-source project created by my mentor, Asfandiyar Khan, a senior frontend engineer based in Germany.Aktion is a streaming-first UI framework designed to turn compact, JavaScript-shaped instructions into reactive and interactive user interfaces.Instead of producing another Markdown response or a large block of frontend code, an AI model can progressively genera

I'm building a shopping app you talk to — here's the stack
You're in the kitchen, fridge open, phone in the other hand. You hit one button and say: "a couple of bananas, milk, a dozen eggs and some chicken breast."Your shopping list now looks like this:[ { "name": "Banana", "quantity": 2, "category": "Produce" }, { "name": "Milk", "quantity": 1, "category": "Dairy" }, { "name": "Egg", "quantity": 12, "unit": "dozen", "category": "Dairy" }, { "name": "Chicken Breast", "quantity": 1, "category": "Meat" }]That's real output from the parsing Lambda — "a

URL State in the Next.js App Router: How I Stopped Losing UI State on Refresh
Headline: URL state means storing UI state — filters, active tab, search query, pagination — in the URL query string instead of React useState, so a refresh, a shared link, or the back button restores exactly what the user saw. In the Next.js App Router I read it with useSearchParams() or the async searchParams prop, write it with router.replace(), and reach for nuqs when I want a type-safe, useState-shaped API. The trap that cost me an afternoon: a component calling useSearchParams() must sit i
