How Pagination Works — And Why Every Developer Needs to Understand It 📄
You open an app. It loads 10,000 records all at once. Your browser freezes. Your users leave. 😬Sound familiar? That's the pagination problem in reverse — what happens when you don't use it. Pagination is one of those concepts that looks simple on the surface but quietly powers almost every real-world app you've ever used: Google Search, Twitter feeds, product listings, admin dashboards, and more.So how does it actually work? And how do you build it? Let's break it all down from scratch — with a
How We Improved Frontend Engineering Productivity by 18% Using AI (Real-World Approach)
ContextAI tools are everywhere in software development right now.Most teams are experimenting with them.Very few are seeing consistent, measurable impact.In this post, I’ll share a practical approach we used to integrate AI into frontend engineering workflows - and what actually worked. The ProblemWe had a fairly mature frontend setup:React + Next.js architectureDesign systems in placeMultiple teams working across business unitsBut we still faced:Variability in component qualityRepeti
You Might Not Need a Framework: Building Modern Web Apps with Vanilla JavaScript
In today's frontend world, it's easy to reach for React, Vue, or Svelte the moment a project needs interactivity, state management, or routing. But the modern browser has evolved dramatically. With native DOM APIs, the History API, Web Components, and powerful language features like Proxies, you can build rich, performant single-page applications (SPAs) using nothing but Vanilla JavaScript.This approach gives you:Smaller bundle sizesBetter performance (no virtual DOM overhead)Full control and un
Stop Defaulting to WebSockets: A Practical Guide to SSE, Polling, and Knowing When You Actually Need Them
Stop Defaulting to WebSockets: A Practical Guide to SSE, Polling, and Knowing When You Actually Need ThemYou've been there. A ticket lands in your sprint: "Make the dashboard real-time." Your brain immediately jumps to WebSockets. Open a persistent connection, push data to the client, done — right?Not so fast.In my experience (and the experience of plenty of devs who've debugged WebSocket auth issues at 2 AM), WebSockets are overkill for most "real-time" features. Notifications, live feeds
In 2026 everyone is talking about AI-powered build tools.
In 2026 everyone is talking about AI-powered build tools.But nobody is talking about the real bottleneck.Your AI assistant generates code in milliseconds.Then your build tool spends 40 seconds reprocessing modules it saw yesterday.The bottleneck isn't your AI. It's your stateless build pipeline.Ionify fixes the part everyone forgot:→ Persistent dependency graph→ CAS: every transform stored by content hash→ 100ms warm rebuilds on 11k+ modulesYour AI deserves a build engine that keeps up.Ionify is

Next.js 15 vs. Remix 3.0: React Server Components Throughput on Vercel 2026 Edge Network
In Q3 2026, Vercel’s Edge Network processed 1.2 trillion React Server Component (RSC) requests monthly, up 400% year-over-year. Yet 68% of teams we surveyed still can’t quantify RSC throughput differences between Next.js 15 and Remix 3.0 on this infrastructure. This article fixes that: we ran 12,000 benchmark iterations across 4 Vercel Edge regions, measured p50/p95/p99 latency, memory usage, and cold start times, and documented every configuration step so you can reproduce our results. 🔴 L
I indexed 17,341 polynomial fan curves in Postgres and matched a duty point in <100ms
Most B2B HVAC catalogs publish fan performance curves as scanned PDFs. Engineers do the interpolation by eye when they need to know "will this fan deliver 5,000 m³/h at 350 Pa?" — they overlay the operating point on the curve image and squint.I wanted a catalog where the curves compute. Here's what that took. TL;DRI parsed 17,341 fan curves from manufacturer PDFs into 3rd-degree polynomial coefficients, stored them as JSONB arrays in Postgres, and built a selection engine that ranks all 17,
Under the Hood: React 19's New Reconciler and Vue 3.5's Vapor Mode
After 18 months of RFC debates and 12,000+ commits across both frameworks, React 19’s re-engineered reconciler and Vue 3.5’s Vapor Mode represent the most significant virtual DOM (VDOM) architectural shifts in a decade—delivering up to 40% faster initial renders and 60% lower memory overhead for complex enterprise apps, according to our benchmark suite. 📡 Hacker News Top Stories Right Now GTFOBins (38 points) Talkie: a 13B vintage language model from 1930 (288 points) Microsoft and OpenA
Build a playable 2D game in React — from zero to ~40 lines with CarverJS
Most game tutorials for web developers start with "install Unity" or "set up a canvas context." Both paths lead somewhere real — but if your game lives inside a React app, you want your game loop to compose with React state the same way everything else does.CarverJS is a React game engine built for that case. v0.0.1, APIs will move. But the core hooks are stable enough to build with today.Here is what a complete playable 2D game looks like from scratch. What you'll buildA player square that

I Built a Neural Memory Layer for a Voice AI Assistant: Embeddings + Vector Search + Activity Neurons
My voice AI asked me for the third time whether Sylvie was my sister or my mother.That's when I understood what was missing in every voice assistant I'd shipped or used: persistence. Modern LLMs are smart, but each conversation starts from scratch. You explain who's who, what your constraints are, what your habits are. And tomorrow you do it all again. The intelligence is real, but it doesn't compound.So this week I shipped Memory in TAMSIV (my Android voice task manager, ~850 commits, solo dev)
