🚨 “It works on my machine.” The developer's most dangerous sentence 😂

Your app works perfectly locally, then suddenly breaks in production.

Before blaming the code, check:

🔹 Environment variables 🔹 Node.js versions 🔹 Database connection 🔹 API URLs 🔹 CORS configuration 🔹 Production build settings

Local success ≠ production readiness.

Always test your application in an environment as close to production as possible.

What’s the funniest “works locally, breaks in production” bug you've faced? 👇

Rhythm: An AI daily planner that plans when, not just what

I kept missing my own basic goals. Drink water, stretch, read for twenty minutes: I had no trouble writing them down, I just never had a place to put them. Every habit app I tried handed me a list and left the scheduling to me, and "later" always lost to whatever the day actually threw at me. So I built the tool I actually needed.

Rhythm takes the fixed shape of your day (wake time, sleep time, work hours) and slots your goals into the real open windows around it, using an AI scheduling engine that explains its reasoning for every placement instead of acting as a black box. It handles three distinct kinds of goals: simple recurring habits, several-times-a-day reminders (spaced automatically, tightened on the fly if you skip one), and bigger goals broken into a paced, multi-week plan toward a deadline you set.

Built with Next.js, React, and a real OpenAI-backed scheduling API, with a calm, warm, journal-like design system, hand-tuned color and type tokens, organic shapes instead of generic dashboard chrome, and zero gamified streak badges. Every screen, from onboarding to the reasoning card behind each task, was designed to feel like a planner, not a productivity dashboard.

This is the first pass, an early design concept proving out the core idea. What's here is a working web prototype; what's next is a proper native mobile app with real push notifications, calendar sync, and a fuller feature set built on top of this foundation.

I really need this !!!
