Self-hosting the thing I paid not to think about

A managed service is a deal: you pay to not think about what’s underneath. I self-hosted Supabase on a 16GB box over a weekend, with AI help, and made every component earn its place. What I bought back was understanding.

claude-compass — working notes

Notes on my rule-based guard for Claude Code: the hook contract, the Python/Go pair, the shared test set, and the holes I found along the way.

Kimchi's terminal UI on first launch in the brew-buddy repo — the opening prompt reads 'hi kimchi welcome to my homelab. My name is Janos and i'd like to try you'

I gave Kimchi my kombucha app

Same builder model, same task, two harness modes — a real feature on my homelab, and why the architecture, not a smarter model, decided every outcome that mattered.

Nothing Ever Deorbits

55 years of dev tools as orbital debris. If you feel behind: nobody can keep up with this. It’s not you. It’s the sky.

The Coding Skill That Actually Degrades Isn't Syntax — It's Judgment

Everyone worries that coding with an LLM makes them forget how to code. That’s the wrong thing to worry about. The skill that really degrades is judgment — knowing when to trust the model and when to take the keyboard back.

🧱 An Agent Audited My Homelab — and the Useful Part Was Telling It 'No'

I gave a second AI read access to the Git repos that define my k3s homelab. The findings were fine — the work was validating each: which to accept, which to recalibrate, and which the scanner was confidently wrong about.

I Let Two AIs Argue Over My Homepage — To See If They Actually Think Differently

A single model playing scrum master is just one mind doing all the voices. So I gave two models from two different labs the same deliberately vague design brief, let them collide, and watched what each one refused to give up. I wasn’t trying to prove the merge was better — I was trying to prove they were different.

🎨 I Gave My Blog a Mascot and Never Drew a Line

Thirty posts, no covers, and I can’t draw. The fix wasn’t a better prompt — it was picking the right model tier and letting the model read the whole post.

The Third Bird Reads People, Not Pages — and Never Hits Send

Two birds already read the web for me. The third one reads people — it mines my GitHub graph for humans worth a first message and writes the opening line, but it never sends. The word that changed the whole design was ‘who’, and the trap it had to dodge is that finding people like me is exactly the easy thing embeddings do best.
