I Built a Skill Registration Framework for AI Agents in 3000 Lines of TypeScript

I was tired of every AI agent framework having a different way to register tools. So I built one that works for all of them. ## The Problem If you've built AI agents, you know the pain. Every framework — LangChain, AutoGen, CrewAI, OpenClaw — has its own way to define tools and skills. Want to add a weather API? Different syntax everywhere. Want credentials? Good luck figuring out each one's app...

This is a submission for Weekend Challenge: Earth Day Edition What I Built Solving carbon emissions often starts with efficiency. This project reimagines how we move goods or people by finding the most "carbon-efficient" routes rather than just the fastest ones. A routing engine that calculates the CO_2 cost of different transit methods based on real-time data. It doesn't just show a ...

Cloud sync is a feature you’re paying for with your privacy

Open a new app. Create an account. Verify your email. Choose a plan. Grant permissions. Now you can take notes. This is the default in 2026. And most developers just accept it. I've been building local-first terminal tools for a while now, and the more I do it, the more convinced I am that the industry defaulted to cloud sync not because it's better for users, but because it's better for retenti...

Value Objects, Entities, and Aggregates in Go — Without a Framework

Domain-Driven Design in Go doesn't look like DDD in Java. There are no annotations, no repository interfaces from a framework, no @Entity markers. The building blocks — Value Objects, Entities, and Aggregates — emerge from Go's type system and encapsulation rules. Here's how each pattern appeared in a security CLI through refactoring, with the actual before/after code. Value Objects: Eq...

Next.js 16.2 Turbopack: 400% Faster next dev — What It Actually Feels Like

Next.js 16.2 shipped last month with one headline claim: next dev\ is now 400% faster. The official release notes promise 10x HMR on large projects. Turbopack replaces Webpack as the default bundler. I've been running it on five production-grade template repos for two weeks. Here's what that actually feels like in practice. The Boring Answer: Yes, It's Fast Here are the numbers I saw ...

Material Design Principles Are Correct. Implementing Them Will Break You.

Long read. Written from nine years of implementation experience, not the spec. Preface I believe Material Design is correct. Not partially correct -- correct in its core philosophy about how interfaces should behave under load, under interaction, under uncertainty. I follow new versions closely. I implement what I can, whenever I can. I use a Pixel phone specifically because the s...

I built a terminal screensaver in Go — constellations, rain, braille waves, and full shell integration

Every OS has a screensaver. The terminal had nothing. So I built drift — a terminal screensaver written in Go that activates automatically when your shell goes idle and disappears the moment you press any key. https://github.com/phlx0/drift How it works drift is built on tcell and renders directly to the terminal at a configurable frame rate (default 30fps).

Hono.js on Cloudflare Workers: Typed APIs That Actually Run at the Edge

I've been running Express-style Node servers for years. They work. They're familiar. And for most projects I've touched, they're also overkill — a whole VM babysitting a few hundred requests per day. Last quarter we moved our AI agent webhook layer to Hono on Cloudflare Workers. Here's what that actually looks like in production, where it breaks down, and what I'd do differently. What H...

How I Found My First CVE as a College Student (And What Most Guides Don't Tell You)

Has anyone tried FractoState as a high-performance alternative to Zustand or Jotai?

I'm looking for real-world feedback on **FractoState**, a relatively new React state management library. I've been using it on several large production projects and really like these aspects: - **Surgical updates** thanks to its atomic proxy architecture — only the components that actually need a piece of state re-render, even in very dynamic UIs. - Almost **zero boilerplate**: you define a `Flow`...

How to Write a Business Continuity Plan with AI: Step-by-Step Prompts and Tools (2026)

Most small businesses don't have a business continuity plan. Not for lack of risk — for lack of a realistic process to create one. The standard BCP guide assumes you have a dedicated risk team, a compliance consultant, and two weeks to populate a 40-page Word template. That's not realistic for the operations manager at a 30-person company who also handles vendor contracts, office logistics, and w...

After 5+ years of fighting with Puppeteer, Ive come to a realization: it's not getting better. The core issues that make it painful for scraping have been open for years, and the response is always "use a plugin" or "that's not what we buit it for."

Building the Romanian NLP API that should already exist

If you've tried to do anything programmatic with Romanian text, you've probably hit the same wall I did. There's no clean API for it. You end up scraping DEXonline, wrestling with incomplete library support, or calling a general-purpose LLM and hoping it gets the grammar right. None of that is good enough for production. The specific gap Given an arbitrary Romanian sentence, return fo...
