The aggregator grew a conversational chat that searches its own archive, a sentiment dial that bends article ranking toward whatever mood I'm in, and a full-text fetch stage that pulls the act...

How I Added i18n to My Next.js App Router Project

Hey everyone! I recently added multilingual support (Japanese + English) to my side project unsolved — a silly joke app that takes your everyday problems and generates a sci-fi story about how "humanity's collective wisdom" solved it. 😄 Since the concept is kind of universal (everyone has problems, right?), I wanted English-speaking users to enjoy it too. So I went ahead and implemented i18n. I...

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...

If you're building a trading bot, fintech SaaS, or analytics dashboard, choosing the right API early can save a lot of headaches late...
