Picture a settings page. There's an Export control in the toolbar, a filter dropdown, and a Settings dialog. Everything works when you click. Now push your mouse aside and press Tab. The focus ring has vanished, Export never receives focus, and the dialog opens while keyboard…
I don't know Premiere. I didn't want to learn it just to make a 30-second trailer for a side project. So I made the video a web page instead. The idea The whole trailer is one 1920x1080 page where everything on screen is a pure function of time. No timers, no animation…
Every Python programmer eventually hits the same wall: the script works, but you want colleagues without a Python environment to use it — which means it needs a web page. Suddenly you're facing HTML, CSS, JavaScript, maybe npm and a build toolchain. Most people stop at that…
Caching is one of the most effective ways to improve application performance. It can also produce some of the strangest bugs developers encounter. Why Cache? Suppose a page repeatedly requests the same expensive data. Without caching: Request ↓ Application ↓ Database ↓ Response…
Sooner or later almost every web project needs something to happen on a schedule: send the newsletter at 8, clean up old sessions every night, import a price feed every 15 minutes, run wp-cron.php reliably. On a VPS you open crontab -e and you're done. But many projects don't…
Every sticker app I tried gave me generic cartoons. I wanted stickers that are unmistakably me — so I built StickersMaker. AI Animated Sticker Maker from Photos | StickersMaker Turn one photo into a reusable cartoon character and create transparent animated stickers for…
Per-site, per-view, template fragment, low-level: most developers only know one, and it's usually the wrong one for the job. Caching is the highest-leverage performance tool in Django. A cached response can be hundreds of times faster than one that hits the database and renders…
Home-improvement cost calculators have a credibility problem: a single number looks authoritative even when the underlying job varies by climate, equipment, ductwork, permits, and contractor scope. We built Clear HVAC Costs around a different idea—show a defensible range, expose…
There is no thing like startup technology adoption compared to enterprise technology adoption. Enterprises seek power; business outcomes. They conduct pilot run before commitment, invest before deployment and insist on longevity of vendor before architectural bet. Enterprises…
Skills Are Guidance, Not a Security Boundary: A Next.js Server Action That Stays Server-Side It's 3:00 AM. Your on-call pager fires: leaked API keys in a production bundle. The incident trace shows a shared utility file—imported by both a Server Component and a client…
A beauty studio website can look elegant while leaving a first-time visitor with several unresolved questions. Which treatment should I choose? What does the price cover? Which location should I visit? Does clicking “book” actually reserve an appointment? For developers and…
You asked Claude, ChatGPT or Cursor for a quick internal tool: a pricing calculator, a chart over last quarter's numbers, a clickable onboarding checklist. It works on your machine. Now a product manager, a client or your finance lead needs to open it, and they are not going to…
When several people look after the same person, each may know something the others do not. One knows whether lunch was eaten. Another has booked the next appointment. Someone else remembers a question that still needs an answer. Before taking over, a caregiver needs to read what…
A few years ago, creating a professional website often meant hiring a developer, learning to code, or spending hours customizing templates. Today, AI website builders can turn a written description into an initial website structure, suggest content, and help users refine page…
A catalog operator messaged us last week: every call to our paid endpoint was failing on their side. Our monitoring was green. Our own test client settled payments against the same endpoint that morning. Both of us were right, and that is the interesting part. The shape of a 402…
I spend a lot of time in the AI space -- reading papers, building things, talking to engineers who are actually shipping. And there is a gap between what the demos show and what production systems actually look like that nobody is being fully honest about. So here is my honest…
Most developer portfolios are a dark gradient with a glowing card. I wanted something people would remember, so mine is a newspaper : The Nandan Review . Underneath it is a small design system I call The Press . This post is about how it works, why the newspaper idea held…
We named the murder statue Peanut There is a statue in a locked room. It is rebar and concrete, and if you blink while you are in the room with it, it is already behind you, and it breaks your neck. That is the whole creature. That is all it does. Fans of the fiction call it…
An unset environment variable is still undefined at runtime, even when TypeScript code uses a non-null assertion. Catching that configuration error before a request makes the first call easier to debug. The BlockVectra Data API TypeScript client now rejects a missing, empty or…
Why Add AI Voice to Your Django App? Voice has become the new “screen” for many users. From hands‑free navigation to accessibility, integrating AI‑generated speech can make your Django project feel more natural and inclusive. Whether you’re building a customer‑support chatbot,…
A cleaner diff can help you understand a change. Before you merge, check what your review settings left out. You ask AI to fix one bug. It returns a change that also reformats half the file. Now you have two problems: understanding the fix and finding everything else that moved.…
Why “human‑like” matters in AI voice When you hear a synthetic voice that sounds too robotic, the magic of your app disappears. Users start focusing on the odd cadence, the flat intonation, and the lack of emotional nuance. In a world where voice assistants, audiobooks, and…
Building an Interactive Rain-on-Glass Effect with Three.js and WebGL I've been experimenting with Three.js and WebGL while working on my personal portfolio. One of those experiments turned into Rain on Glass. An interactive effect where water droplets fall onto a virtual glass…
Thinking About Open-Sourcing Talk Octopus: https://www.talkoctopus.com/ (DocSend Alternative) Good Idea or Mistake? I'm the solo founder of TalkOctopus, a platform that helps users share documents and track engagement, similar to DocSend. Lately I've been considering an…
Voice AI in 2026 – A Developer‑Centric Comparison Voice has become the new UI. From conversational agents to audiobooks, the demand for high‑quality, expressive text‑to‑speech (TTS) is exploding. By 2026 the ecosystem has narrowed to a handful of mature platforms, each with its…
I gamified my GitHub streak into a garden I’d lose my commit streak on busy days, and GitHub’s contribution graph never really cared. So I built Commit Garden: a tiny garden that depends on whether you pushed code today. What it does Connect GitHub once. Every day you push, your…
Bitcoin can't run on Ethereum. So when a lending market or a DEX pool on Ethereum says it accepts "BTC", it means something else: a token that promises a real bitcoin is sitting somewhere, waiting to be redeemed. That promise has a structure. Someone holds the BTC, someone…
You build a small app. It works great on your laptop. Then someone asks, "Cool, where is it hosted?" and suddenly you're reading about servers, ports, uptime, and updates when you just wanted to ship a feature. 😅 That's the moment many developers first hear about a serverless…
I sell HTML templates. Yesterday I found out that every mobile preview in every one of my product listings showed the product broken — cards clipped off the right edge, text cut mid-sentence, a button sliced in half. The templates were fine. The screenshots were wrong. Here is…
Slow down. Sort smarter. Keep your originals safe. Ever opened your Downloads folder and found yourself staring at hundreds of files, promising you'll organize them someday? I decided to build something to make that task easier. Meet SlothSort AI, a local-first file organization…
When you're designing a branch circuit or sizing the conductors for a panel feed, the conversation quickly narrows to one question: how much voltage is going to disappear between the source and the load, and what wire size will keep that drop acceptable? Electrical codes and…
How a free, open-source plugin helps developers, privacy professionals, and SMBs tackle GDPR tasks directly inside Claude Code. Data protection compliance is often seen as a legal exercise rather than a development workflow. Yet modern teams increasingly need to address privacy…
Water-quality monitoring is a useful example of how web development can connect data with real-world systems. A dashboard can display measurements such as pH and water temperature, show the time of the latest reading, and flag values that need review. In this tutorial, we will…
Fairness is easy to claim and hard to prove in a 3D runner. In CGT Rocket X Racer, a fan-made rocket-car runner that plays in a desktop browser, the two hazards players blame first are giant presses and sweeping robot arms. If either feels random, every other system — parts,…
Most small-business websites don't go down because of a clever attack. They go down because of something boring that nobody was watching: a certificate that expired on a Sunday, a domain renewal that failed because the card on file changed, or invoices that land in spam for…
The hardest part of a small-business website isn’t always the design. Sometimes it’s making sure the right website actually appears when someone visits the domain. I’ve been building a website for Din Borlänge Taxi AB, a local taxi company. The goal was straightforward: help…
I make custom printed sneakers. People upload a picture, we print it onto the leather panels of a shoe, and somewhere between those two steps the picture stops being a picture and becomes a set of manufacturing instructions. That middle step is a browser-side canvas pipeline,…
Every few months I'd sit down to "finally learn the terminal properly." I'd open a cheatsheet, read through ls, cd, grep, chmod, nod along like it made sense, and then forget 80% of it the moment I closed the tab. The commands never stuck because I was memorizing them, not using…
I didn't change a line of code. The feed changed, and Google News had been saying no the whole time. Hi! I'm Tim, a self-taught developer in Nairobi. I build small data tools that run as Apify Actors, serverless jobs that people pay for per result. Apify runs every public Actor…
On October 21, 2026 the PHP project shipped emergency releases for two critical remote-code-execution bugs in the language runtime itself. The headline most outlets chose is "AI found it". The more useful part is what the PHP Foundation says about why it took so long to fix.…
Software as a Service (SaaS) has become one of the most practical ways to deliver software, generate recurring revenue, and scale products without distributing installations to individual customers. From project management platforms to CRM systems, modern SaaS applications rely…
Landing pages are full of things that act like buttons: "Get started", menu toggles, tabs, plan switchers. Some are real <button> elements. Some are a <div> with a click handler. The page looks identical, but keyboard and screen reader users get different pages. The check View…
A while ago I wrote an article about using object literals instead of switch statements , and I still think the idea behind it is a good one: map an input to an output, skip the long list of case and break , and keep your code short and readable. But there's a catch I didn't…
A new group on a call is a room of muted microphones. Nobody wants to speak first, and the host fills the silence with an apology. The cure is an activity that asks nothing personal and gives everyone something to do. These icebreaker games online suit groups from four to…
Originally published at webtricks.dev , where the liquid glass card snippet has a live playground. Apple's Liquid Glass (introduced across iOS, iPadOS and macOS in 2025) is the current reference for translucent UI. The good news: around 80% of the look is plain, well-supported…
In Margin, the user needs room to work on an idea. In SayPay, the user needs to understand a proposed payment before approving it. I built these two independent projects with AI assistance, but they serve different purposes. This is a closer look at the applications and the…
Ein leeres Zahlenfeld und die ausdrücklich eingegebene Zahl 0 können im Formular ähnlich unspektakulär wirken. Im Datenmodell beschreiben sie unterschiedliche Situationen. Wer beide Zustände gleich behandelt, verliert eine Information, die sich später kaum noch zuverlässig…
Tout le monde appelle ça « la page blanche ». Le terme est resté des années 2010, quand un plugin cassé laissait effectivement un écran vide. Aujourd'hui, dans l'immense majorité des cas, votre écran n'est pas blanc : il porte une phrase. Et cette différence décide de l'endroit…
You already have Java endpoints, input validation, and HTML templates. Now you want inline editing and live search without maintaining a separate application in the browser. HTMX lets an HTML element send an HTTP request and replace a selected part of the page with the returned…
Your app is live. You tested signup, you tested the main feature, everything worked. Then a week later someone replies to your launch post: "Is your site broken? I can't log in." Too often, that is how founders find out their app is broken: from a user, days late, after other…
