Ed25519 vs ECDSA: Why the Nonce Decides Everything

ECDSA and Ed25519 both sign data with elliptic curves, and both produce a 64-byte signature that verifies in a fraction of a millisecond. The difference between them is almost invisible on paper: ECDSA needs a fresh secret random number for every signature, and Ed25519 computes that number instead. That one design choice is the reason real people have lost real private keys. A digital signature a...

Filtering, and Pagination in Next.js 15 The Pattern I Actually Use

Every dashboard eventually needs the same three things. A search box, a few filters, and pagination once the list gets long. The version I used to build kept all of that in useState, which meant losing your filters the moment you refreshed the page or shared a link with someone else. Keeping this state in the URL instead fixed both problems at once. Here is the setup. 1. Why URL Sear...

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...

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'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.
