Cloudflare for Developers: What It's Great At, Where It Bites, and How to Actually Use It

Cloudflare is best understood not as "a CDN" but as a programmable network that sits between your users and your origin, plus a growing platform for running code and storing data at the edge. For most developers the wins are real and immediate — free TLS, a fast global CDN, DNS you don't have to babysit, and a serverless runtime with almost no cold start. The catches are just as real: the Workers ...

Stack Overflow vs AI Coding Assistants: How Developers Solve Problems in 202

A decade ago, if you hit a weird stack trace at 11pm, you opened a new tab, typed your error into Google, and landed on Stack Overflow. Today you probably don't leave your editor at all. You just ask the AI assistant sitting in your sidebar. That shift isn't a vibe — it's a measurable collapse. And it's changed not just where developers get answers, but how they think about getting unstuck in the...

The Review Tax: Escaping AI Code Review Traps with AWS Kiro Crew Orchestration

Originally published on tamiz.pro. In the modern software development lifecycle, Artificial Intelligence has become the ubiquitous intern that never sleeps but occasionally suggests deleting your main branch. While AI coding assistants have drastically accelerated boilerplate generation, they have inadvertently introduced a new, hidden cost to engineering teams: The Review Tax. This is the cumula...

Functional programming with TypeScript: what fp-ts teaches you even if you never ship it

Functional programming with TypeScript: what fp-ts teaches you even if you never ship it The correct solution for handling nullables in TypeScript is to add more types. I know that sounds like bureaucracy. But it was exactly the idea behind fp-ts's Option<T> that made me realize every undefined I was returning without context was a broken contract waiting to blow up at runtime — I...

Growing Up The Hard Way

Open Source had a great childhood. For two decades it got to be a kid. It ran around barefoot, gave everything away, trusted strangers, and never once thought about who was watching. It ran the kind of lemonade stand that took IOUs from anyone who wandered up — take what you need, pay me back whenever, no need to leave a name. It was idyllic. It was also, in retrospect, a little feral. Then,

Ship a Production RAG Chatbot in a Weekend with Claude, pgvector, and FastAPI

You can stand up a genuinely useful retrieval-augmented chatbot in a weekend with three moving parts: Postgres (plus the pgvector extension) as your vector store, a FastAPI service as the glue, and Claude for the generation step. The one thing that trips people up on day one is that Claude has no embeddings endpoint — you bring your own embedding model, and everything else is standard web plumbing...

I built 59 free browser-based dev tools in vanilla JS — here's what I learned

I've been quietly building Antigravity Tools — a collection of 59 free, browser-based developer utilities — and today I'm sharing everything I built and learned. Why vanilla JS? No React, no build step. The main constraint I set for myself: zero dependencies, zero server, zero telemetry. When you paste your JWT token into jwt.io, it goes to their server. When you use an online regex t...

Puck 0.23 (visual editor for React) adds new drag-and-drop for reduced layout shift

Hi r/reactjs! We just released Puck 0.23, which introduces a new "static" drag-and-drop mode. Puck lets you drag-and-drop your own React components. Because we support nested layouts with any CSS display modes, this sometimes results in layout shift. To help with this, we just added a new "static" drag-and-drop mode that shows a line when dragging between parent (we call them s...

Bug: cross site cookie restrictions

What went wrong? When a user logged in on my deployed frontend (https://domainA.app), the credentials succeeded, but they were immediately treated as unauthenticated. Protected endpoints (like /stats/admin/*) failed with a 401 Unauthorized status code. Crucially, this behavior did not happen on localhost. Why did it happen? This is caused by cross-site cookie restrictions ...

What are Agent Plugins?

Implementing Agent Skills and MCP servers as part of my development workflow has been a huge boost to my productivity. Long gone are the days where I'd actually have to leave my IDE to raise a pull request in GitHub, and then manually add that PR to a Jira ticket that's still impossible to find in 2026. Now it's just a matter of me asking GitHub Copilot to create the PR using my create-pr Agent ...
