I built a self-improving home server that autoconfigures itself

I built Talome over the last couple of weeks. It's an open-source home server platform (AGPL-3.0) where AI is the primary interface. You tell it what you want in plain English, and it does the work — installs apps, wires services together, monitors containers, creates new apps, and when I'm really a...

How I'd Design a Memory System for an AI Companion App

I spent 200 days testing 15 AI companion apps. Paid for every subscription myself. Talked to each one for weeks, sometimes months. The single biggest thing separating the good ones from the bad ones?

Your AI Stack Is Too Big

Performance wins almost always come from architecture, not model size. Your users feel the delay long before they read your roadmap. If you're d...

I hit a wall recently. I had a working AI SDK app -- streamText, useChat, the whole thing -- and then I needed it to do something that a single agent can't: research a topic with one agent, then hand that research to a second agent for writing. You can do this manually. Glue two generateText calls...

Feature flags that show you how your rollout is actually performing

Most feature flag tools tell you whether a flag is on or off. They don't tell you if it's actually working. You deploy a flag, start rolling it out to users, and then... what?

AI Is Changing What Understanding Code Means

For a long time, understanding code meant something very concrete. If you could read it, write it, and debug it — you understood it. That definition is quietly breaking. Not because code is becoming simpler. But because the way we interact with code is changing. The Old Definition o...
