I built a free browser-based QR and barcode generator with local-only rendering

I built QR Barcode Kit as a small browser-based toolkit for creating static QR codes and common barcode formats without uploading data to a server. The tool currently supports: URL QR codes WiFi QR codes vCard QR codes General barcode generation Code 128 barcodes EAN-13 barcodes The main reason I built it this way is privacy and speed. The generated code is rendered locally in the browser, so the input does not need to be sent to an account-based dashboard or backend API. Useful pages: QR Code G

When (and when not) to inline images as Base64

Base64 image data URIs are one of those web techniques that look like a magic shortcut the first time you use them. Instead of referencing an external file: you can put the image bytes directly in the document as text: That can be useful. It can also make a page slower, harder to cache, and more annoying to maintain. Here is the practical rule: inline images as Base64 when self-containment matters more than caching. Keep normal image files when the browser should be able to cache, resize, lazy-l

Fine-Tuning Is Mostly Theater. Here's What Works Instead.

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 take on where things actually are. Everyone is calling everything an "agent" right now. A function that calls a tool? Agent. A chatbot with memory? Agent. A script with a loop? Agent. This dilution is not just semantic. It

I Ranked 30 AI APIs by Price and the Results Are Wild

I Ranked 30 AI APIs by Price and the Results Are Wild Last month I burned through $400 testing different AI models for a side project. That's when I went down the rabbit hole of API pricing, and honestly? I couldn't believe what I found. Some models cost 350× more than others for what feels like basically the same output. So I pulled together every price I could verify, and what I'm about to share saved me from making one of the dumbest financial decisions of my dev career. Here's the thing: mos

React me Ternary Operator vs Short-Circuit Rendering Kya Hai

हेल्पफुल और प्रैक्टिकल कोडिंग वर्ल्ड में आपका स्वागत है, मेरे दोस्त! अगर आप ReactJS सीख रहे हैं, तो आपने एक बात ज़रूर नोटिस की होगी कि हमारे नॉर्मल JavaScript वाले if-else कंडीशन्स JSX के अंदर सीधे काम नहीं करते। ऐसा इसलिए होता है क्योंकि JSX केवल Expressions को समझता है, Statements को नहीं। जब भी हमें React components में कंडीशन के आधार पर अलग-अलग UI दिखाना होता है, तब हमारे पास दो सबसे बड़े हथियार आते हैं: Ternary Operator (? :) और Short-Circuit Evaluation (&&)। आज हम इन दोनों के बीच के अंतर,

Browser Video Editor: Trim, Cut, and Export MP4 Without a Server

Browser Video Editor is a video editor that runs entirely in your browser. You import local clips, trim them, arrange them on a timeline, drop text overlays on top, scrub a live preview, and export a real .mp4 — and the video files never leave your machine. No upload, no backend, no server doing the encoding. I built it with Claude as a pair programmer, and v1 is complete and merged to master. The shape of it is a Classic non-linear editor: a media bin on the left, a preview canvas in the middle

How TypeScript Infers Types Through Async Generators in 2026

How TypeScript Infers Types Through Async Generators in 2026 Most async generator type errors stem from TypeScript's fundamental constraint: the compiler cannot infer what calling code will send to yield expressions. This limitation creates silent type holes in codebases that rely on async generators for streaming operations, pagination, or event processing. The async generator pattern appears deceptively simple. Developers write async function* expecting TypeScript to infer types from yielded v
