I'm 16 and building a "Chat-to-Edit" AI video tool. Here’s why.

Hey Dev Community! 👋 I’m Shivani, a 16-year-old developer from India, and I’ve spent the last few months obsessed with one question: Why is video editing still so manual? Even with all the AI tools out there, we’re still stuck dragging clips on a timeline, manually cutting silences, and fighting with caption alignment. I wanted to see if I could build a workflow that feels more like a conversati...

10 Questions Every Non-Technical Founder Should Ask Before Their First Web App Build

TL;DR: Most non-technical founders pick a build approach (no-code, freelancer, agency, AI tool, hybrid platform) before they've defined what "done" looks like. The result is rebuilds, rewrites, and bills nobody planned for. This post gives you ten questions to ask yourself — and any vendor — before you commit to a build path. Use it as a checklist on your next call. If you're a non-technical fo...

Most People Don’t Need More AI Tools. They Need Clarity

I’ve been using AI for months now. Not casually, seriously. And I’ve started noticing something uncomfortable. The Observation Every week there’s a new AI tool. A new assistant. A new model. A new productivity layer. People keep asking: What tool should I use? What stack do I need? What’s the best AI workflow? And I’ve noticed something strange. The people chasing the most tools often seem ...

How I got my AI agents to communicate across repos — and shipped SAMP doing it

Situation. I was working on lumen-argus, a project that runs across three Claude Code sessions in three different repos. They needed to share context — "I just refactored the auth module," "the schema migration landed, pull main." For weeks I was copy-pasting between terminal windows like a caveman. Task. I wanted cross-session, cross-repo messaging for AI agents. Cheap. Fast. Local. Ideally some...

Pinterestメディアスタックの解読：非同期I/OとFFmpegによる高性能ダウンローダーの構築

はじめに エンジニアとして、私たちは日々、大規模プラットフォームがどのようにコンテンツを配信しているかに興味を引かれます。Pinterestは単なる画像共有サイトではなく、視覚的発見を支える巨大なメディア配信エンジンです。しかし、開発者がアーカイブツールを構築しようとする際、Pinterest独自の動的レンダリングとアダプティブ・ビットレート・ストリーミング（ABR）は大きな技術的障壁となります。 この課題を解決するために、私はPinterest ビデオダウンローダーを開発しました。本記事では、このツールの裏側にある技術スタック、特にPython Asyncioによる非同期処理、HLS（HTTP Live Streaming）のリアルタイム変換、そしてサーバーサイド・ストリーミング・パイプラインの最適化について詳しく解説します。 1.

Remade the 1991 Classic "Gorillas" in Python—and Survived the Snapcraft Journey

The Nostalgia Hit 🍌 Remember the two gorillas standing on a skyline, tossing exploding bananas at each other? I decided to bring that back. I built a remake of the classic QBasic Gorillas using Python and Pygame. It has everything: Randomly generated city skylines. Parabolic physics (gravity is a beast). The classic sun that reacts when hit. Screen shake for that "modern" retro feel. ...

🚖 Designing an Uber/Ola-like Ride Booking System (LLD + UML Approach)

When I started practicing Low-Level Design, I realized that jumping directly into drawing UML diagrams often leads to messy, confusing designs. So instead, I followed a step-by-step approach—breaking the system into components, understanding flow, and then translating that into a clean UML. Here’s how I approached designing a simplified Uber/Ola system. 🎯 Problem Statement Design a r...

When a Simple Click Gets in the Way: A Tiny UX Detail That Matters

I was browsing Flipkart the other day, doing something pretty routine—comparing products. Nothing fancy. Just scanning titles, checking specs, trying to find the right model. At one point, I needed the model number from a product title. The title was long, so it was truncated with an ellipsis. Fair enough—that's common. So I clicked on it. The full title appeared. Good. Then I tried to selec...
