React useScrollLock Hook: Lock Body Scroll for Modals (2026)
Your modal is open, centered, perfect. Then someone flicks the overlay and the page behind it scrolls away underneath. Everyone's first fix is the same three lines:useEffect(() => { document.body.style.overflow = open ? "hidden" : "";}, [open]);It works on your laptop. Then the bug reports arrive:On iPhone the page still moves. iOS Safari rubber-band scrolls the document by touch even with overflow: hidden on <body>.Something else got wiped. "" isn't necessarily what was there before —
A news-watch bot, an 8,900-character prompt, and three rules that never reached the model
The item sits at the top of the feed. "Last trading day for the first US spot Bitcoin ETF to shut down." Tagged as verified fact. Three sources, all dated August 3rd.It is August 17th.Fourteen days between the most recent source and the event it announces. A shutdown can be postponed. A vote can be adjourned. And I had written a rule for exactly that case a week earlier, a rule that says in plain words never to copy a two-week-old announcement as if it were still true. The setup, for anyone

Conditional Requests Are an Interview Contract: Build an ETag Drill in Node.js
Conditional Requests Are an Interview Contract: Build an ETag Drill in Node.jsAn ETag is not just a cache header. In a backend interview, it is a compact way to show that you can define an HTTP contract, avoid needless transfer, and prevent an older edit from silently overwriting a newer one. This small Node.js drill implements both paths: 304 Not Modified for cache revalidation and 412 Precondition Failed for stale writes.A common interview prompt sounds deceptively simple: "How would you

5 Practical Solutions for Large List Rendering in Vue 3
When rendering hundreds or thousands of items, Vue 3 apps can lag noticeably. We hit this problem in a recent inventory management system — 5,000 items caused 3-second load times and scrolling dropped below 15fps.Here are 5 solutions we tested, ranked by effectiveness. 1. Virtual Scrolling (Best Overall)Only render DOM elements within the visible viewport. We recommend vue-virtual-scroller:<RecycleScroller :items="list" :item-size="60" key-field="id"> <template #default="{ item }"
Measuring Code Quality: Building a Client-Side JavaScript Complexity & Maintainability Analyzer
As codebases scale under aggressive product cycles, functions can easily become bloated with deeply nested loops and excessive conditional branches. This increases technical debt and makes unit testing much harder.To help developers audit their code hygiene instantly and securely, we built a JS Code Complexity Analyzer running completely client-side. Here is a technical breakdown of how we calculated McCabe's Cyclomatic Complexity, mapped maximum nesting depths, and approximated the industry-sta
MERN Stack Developer Hiring Guide: Costs & Models
"How much does a MERN developer cost?" Wrong question. I get asked this constantly by founders who hire MERN stack developers for the first time, and it's not their fault, it's just the wrong starting point.A $25–$50/hour offshore developer and a $150–$250/hour developer based in the US can both write the exact same React component. Same file, same output, nobody could tell the difference from the diff alone.The difference shows up later. Six weeks in. When the schema needs to change and everyon

Explyt 5.17 Lets It Refactor the Project.
Move, Delete, Rename, run, and debug through JetBrains IDE mechanisms instead of reconstructing project relationships from text alone.AI coding agents are good at producing patches. The harder problem begins when a change crosses file, package, module, or runtime boundaries.Move a class through the file system and its package may become wrong. Delete an entity without checking usages and another module may stop compiling. Rename a symbol as text and unrelated strings can change with it.JetBrains
Premium Ironmongery for Durable Doors, Cabinets & Gates | Infinity Decor
Why Precision Ironmongery Matters in Every Renovation ProjectA renovation can look perfect on the surface, but poor-quality finishing hardware can quickly undermine the entire project.You may choose a beautiful door, install premium cabinetry, or spend time creating the perfect garden gate.

Hire React developers without costly mistakes: a practical buyer's guide
When you set out to hire React developers, the hardest part isn't finding candidates — it's telling a genuinely capable engineer from someone who has memorised the right vocabulary. Most hiring mistakes I've seen come down to three things: conflating years of experience with depth, running the wrong kind of interview, and not knowing what a fair market rate looks like. This post tackles all three. What seniority actually looks like in a React hireJob boards default to years-of-experience cu

Building Tab Timekeeper: A Small Chrome Extension for Making Browsing Time Visible
I built Tab Timekeeper around a small question that is surprisingly easy to lose track of while browsing:How long have I been on this website in this tab?Browsers make it easy to open a page, follow a link, switch tabs, and return much later. What they do not normally show is the time behind that activity. Tab Timekeeper adds that missing bit of context. Click the extension icon and its popup displays a running timer for the active tab, along with the website's favicon.The extension is intention
Building image & video conversion that never leaves the browser
How VisualRefiner converts HEIC, compresses images, and transcodes video with no server, no upload, and no account — using the Canvas API, WebCodecs, and a little WebAssembly.Most "free online converters" work like this: you pick a file, it's uploaded to a server, converted there, and sent back. That's fine for a meme. It's less fine for a folder of personal photos, a passport scan, or client footage under NDA.I built VisualRefiner to do the same jobs without the upload. Every conversion runs in

Your Markdown Parser Is Not Your XSS Boundary
A Markdown parser can produce exactly the right HTML and still leave your application exposed to XSS. Parsing answers what the input means. Sanitization decides which parts of that meaning are allowed to reach an HTML sink.I tested that boundary with Node.js 25.3.0, Marked 18.0.7, DOMPurify 3.4.12, and jsdom 30.0.1. The important comparison is not a screenshot. It is the HTML before and after sanitization. The smallest useful pipelineconst rendered = marked.parse(markdown)const sanitized =
