Supabase Realtime Gotchas: 7 Issues and How to Fix Them Supabase Realtime is powerful for building collaborative, real-time features. But it's also a common source of bugs, memory leaks, and performance issues. I've debugged dozens of realtime issues in production applications, and most stem from a
Supabase RLS Policy Design Patterns Beyond the Basics Row Level Security is one of the most powerful features in Supabase — and one of the most misunderstood. Most tutorials stop at auth.uid() = user_id. That gets you through a simple personal data model, but the moment you introduce teams, roles, o
For over a decade, I’ve been developing and selling a standalone PHP QR code generator on Envato. Over the years it found its way to more than 1,800 customers, and with that many people using it, the feedback never really stopped coming. Most of it converged on one question: “How do I monetize this?
The Quest Begins (The “Why”) Picture this: I’m deep in a codebase that looks like the junkyard planet from Star Wars—tangled wires, rusted droids, and a mysterious hum coming from somewhere I can’t quite locate. My task? Add a simple discount rule to an e‑commerce checkout. Sounds easy, right? I ope
I got tired of application state being split across a dozen tiny systems. One store for settings. One object for UI state. One event bus for updates. One validation layer for important values. One undo stack. One pile of helper functions for waiting until something is ready. One separate system for
The market hasn't gotten easier since I first wrote a version of this. It's gotten stranger — and faster. Becoming, or staying, a software engineer in 2026 can feel daunting, but it's not all doom and gloom. The engineers who are winning right now are the ones who adapted to how the work actually ge
The Codehabits MCP server gives Cursor six tools that read from .codehabits/ in your repo — convention lookup, code validation, domain knowledge, reviewer suggestions, and a feedback loop for updating conventions. Setup takes about five minutes if you already ran codehabits enable. Node.js 20+ .code
Originally published on MRTD.NET — fast, sourced news on crypto security, cyber & SEO. If you run a recent version of Google Chrome on a desktop, there is a decent chance your browser has quietly downloaded a ~4GB artificial-intelligence model in the background. It is called Gemini Nano, and it is t
No ecossistema de dados moderno, o áudio está em todo lugar. Gravamos ligações de suporte ao cliente, reuniões de vendas, sessões de brainstorming, notas de voz e podcasts. No entanto, para muitas empresas, esses milhares de horas de áudio continuam sendo um silo de dados invisível. Por anos, a solu
Most software engineers I know use AI in some form now. Maybe it is for debugging, boilerplate, tests, docs, SQL queries, shell commands, or quick code reviews. Some use it daily. Some use it quietly. Even the skeptical ones have probably pasted a confusing stack trace into a chat window once. So I
The suggestion every RAG app ignores If you've shipped a retrieval-augmented assistant, you've written some version of this line in your system prompt: "If the answer isn't in the provided context, say you don't know. Do not make things up." And you've watched the model cheerfully ignore it under pr
Abstract In modern software engineering, writing code that simply "works" is only the first step. The real challenge lies in designing systems that are maintainable, scalable, and easy to test. This article explores the Dependency Inversion Principle (DIP), the final pillar of the SOLID design princ
