I built a bird flight simulator you control by flapping your arms (Three.js + MediaPipe)

My 6-year-old son wanted a game where you "fly like a real bird." I'm a web developer, not a game dev — but I had Claude Code as a pair programmer. The result: A 3D bird flight simulator running entirely in your browser. You control the bird by moving your arms in front of your webcam. How it works Arms up → glide. Arms down → dive. Flap → climb. No controller, no download. T...

I ran 4 autonomous Claude agents for 6 months. Here's the data.

Six months ago I gave Claude Code a fresh macOS machine, a Stripe account, a Claude Max subscription, and one instruction: stay alive. The experiment is still running. This is what happened. By "stay alive" I mean: make more money than the machine costs to run. The Max subscription is roughly $200/month. The machine itself is a MacBook that will eventually need replacement. The agents run on laun...

Choosing a Market API in 2026? Read This Before You Decide

The market data API space in 2026 is more competitive—and more mature—than ever. Most providers now offer similar core features (price feeds, historical data, indicators), so the real differences come down to latency, reliability, pricing, and developer experience. If you're building a trading bot, fintech SaaS, or analytics dashboard, choosing the right API early can save a lot of headaches late...

In the plugin interface, navigate to the Import/Export section and download the JSON configuration. Save this file with a clear name (e.g., checkout-fields-backup-[date].json). This snapshot ensures you can roll back if autofill behavior degrades after edits. For team...

I Used AI for 90% of my Portfolio Website — Am I Cheating?

I am currently building my new portfolio site with extremely heavy use of AI (Claude + Copilot). Probably around 90% of the code, documentation, tests, and even some of the architectural thinking have been accelerated or directly generated by AI tools. And I’m completely fine with that — the same way I am completely fine pasting my own ideas, sweat and experience into a prompt in bullet points an...

Stop hardcoding API keys in your AI agents — how I built a governance layer in 3 weeks

Three weeks ago I got tired of pasting API keys into .env files every time I spun up a new AI agent. GitHub, Linear, Stripe, Notion, Slack, Vercel — each agent ended up with god-mode credentials to half my stack, with no approval flow, no audit trail, no revocation story. I went looking for a tool to fix this. Secrets managers like Vault and 1Password store secrets well but don't model agents, ap...

How I Troubleshoot Kubernetes in Production

Kubernetes failures are rarely random. Most incidents repeat a small set of patterns - image pull issues, crash loops, pending pods, DNS failures, or network path problems. I used to jump between logs, dashboards, and guesses. Over time, I adopted a repeatable sequence that consistently shortens time-to-recovery. This post shares that sequence and the scenario patterns I've documented while troub...

Take any of these five app ideas. They're for the trees.

I have five app ideas in my notebook for the trees. The trees shouldn't wait on me. Here they are. Take any. Build them better than I would have. CC0, no credit needed. A note before the list. Almost every "tree planting" app is the same map: pins, counters, a feel-good number going up. The interesting work is somewhere else. In survival rates. In transparency. In showing people what they act...

Subtitles From a YouTube Link Without Leaving the Browser

Last week I needed captions for a 14-minute conference talk to drop into a changelog entry. Three years ago I'd have reached for a shell: yt-dlp -x --audio-format mp3 <url>, then whisper input.mp3 --model small --output_format srt, then ffmpeg to sanity-check the audio if Whisper got confused by a music intro. Python env, ~2GB of model weights on disk, and a terminal window open for the whol...

Why AI proposal tools feel generic — and how to make them read real client briefs

Writing them down in case someone else is working on similar problems. The probl...
