The project file is the interface: letting AI agents drive a video editor
Last week I open sourced FableCut,a Premiere-style video editor that runs in the browser and that AI agents canoperate. It hit the front page of Hacker News(thread), and the questionsthere made me realize the interesting part isn't the editor. It's one designdecision: the project file is the interface. The usual way, and why I flipped itMost AI video tools hide the edit behind an API. You call addClip(),applyFilter(), and the tool owns the state. If you want a human to touch theresult, you

Functions in JavaScript
IntroductionFunctions are one of the most important concepts in JavaScript. They allow you to write reusable code, making your programs cleaner, shorter, and easier to maintain.What is a Function?A function is a block of code designed to perform a specific task. It executes only when it is called (invoked).Syntaxfunction functionName() { // Code to execute}Examplefunction greet() { console.log("Hello, Welcome to JavaScript!");}greet();OutputHello, Welcome to JavaScript!Why Do We Use Functi
8 Free Online Tools to Convert PDF to Word, Excel, and PowerPoint (No Install, No Sign-Up)
Converting a PDF to an editable Office file is one of those tasks that sounds trivial until you actually need formatting to survive β tables intact, font sizes correct, images in the right place. Most tools handle plain text PDFs reasonably well. The differences show up on complex layouts, scanned documents, and presentation-style PDFs.Here are 8 free online tools, with honest notes on where each one performs well and where it doesn't. One thing worth knowing upfront: PDF type matters more
Visualizing Crontab: Build and Translate Cron Expressions in Your Browser
Every developer, sysadmin, and DevOps engineer has wrestled with crontab syntax. At a glance, patterns like */15 9-17 * * 1-5 can be challenging to decipher. A single incorrect digit can lead to system resources getting overwhelmed by a runaway process or a critical backup missing its operational window.Rather than looking up crontab specs every time, you can build and translate expressions visually using modern web APIs. Understanding the 5-Part Cron SyntaxStandard crontab expressions are
Faster Compilers, Twelve-Factor Agents, and Kubernetes in Your Browser
The GPU finally got its own origin story: Fergus Finn's bottom-up walkthrough of what actually happens when you run a kernel is the kind of infrastructure literacy that pays dividends whether you're writing CUDA or just squinting at inference latency. Worth the read.On the speed front, the VS Code team's adoption of the TypeScript 7 compiler is peak "benchmark theatre" β in the best way. Type-checking: 36s β 5s. Watch mode: 80s β 20s. If you needed permission to finally take compiler rewrites se
Data Types
Data typesA data type refers to the kind of value a variable holds.JavaScript is a dynamically typed language, meaning the data type is associated with the value, not the variable itself.For example, a variable that currently holds a number can later be reassigned to a string or an object.JavaScript broadly classifies data types into two categories:primitivenonprimitives Primitive Data Types (7)Primitives are immutable and stored by value.Number: Represents numeric values, whether integer o
The Three-Tier PDF Extraction Model: Demystifying PDF.js
TLDR: Every manufactured PDF (not scanned) has three fidelity levels available to a browser-side extractor: a semantic structure tree, a geometric paint stream, and a text convenience API derived from the paint stream. Most tools use only the third. The correct architecture reads them top-down and exits as soon as a tier produces a complete answer.PDF ProcessorRepo The API HierarchyPDF.js exposes three document-reading APIs. They are not three ways of reading the same data. They are three d

Hello Dev Community! πIt is officially Day 123 of my software development sprint! Today, I transitioned from traditional reactive states into state-machine territory by mastering the useReducer Hook in React! βοΈ Unified State ManagementWhen your app state shifts from primitive variables to complex data patterns containing multi-layer transformations, relying on unorganized useState setters spreads logic thin across files.

I Built a React Performance Analyzer as a Graduation Project β It Got 2,700+ Downloads from 25 Countries
A story about building something real, shipping it, and watching strangers use it.A few months ago, my team and I were looking for a graduation project idea. We wanted to build something that actually solved a real problem β not a to-do app, not a clone of something that already existed.We landed on a question that every React developer eventually asks:"Why is my app slow, and where exactly is the problem?"The answer is usually scattered across three or four different tools. ESLint catches some
How I Built Unlimited Cloud Storage Using Telegram's MTProto API in the Browser (No Backend)
I wanted unlimited cloud storage that:Costs nothing to runHas no server I need to maintainDoesn't require trusting a third party with my filesWorks from any browser without installing an appGoogle Drive gives 15 GB free. Dropbox gives 2 GB. Self-hosted solutions like Nextcloud require a server.Then I remembered: Telegram has no storage quota. Files you send to Saved Messages or private channels stay there forever.

I Rebuilt My Habit Tracker's Core Logic as One Hook. Here's What I Learned.
Habit and streak tracking looks simple until you actually build it: timezones, missed days, "does logging at 1am count for yesterday," and the eternal question of whether a streak breaks at midnight or at the user's personal reset time. Most of that complexity belongs in a hook, not scattered across your components. Extracting the logicfunction useStreak(entries, { resetHour = 0 } = {}) { const adjustedDate = (timestamp) => { const d = new Date(timestamp); d.setHours(d.getHours()

Localized Out of the Box with `laravel new` β i18n for Laravel Starter Kits (React/Vue/Svelte)
Laravel's official Starter Kits currently support internationalization (i18n) only in the Livewire version. The Inertia-based kits (React / Vue / Svelte) still have all UI text hardcoded in English. Although support is being discussed upstream (laravel/maestro#168), I created and published localized forks as a temporary solution until official support arrives.React: https://github.com/catatsumuri/react-starter-kit-i18nVue: https://github.com/catatsumuri/vue-starter-kit-i18nSvelte: https://github
