Why I stopped using Vector DBs for AI Memory (and used Git + Markdown instead)

Hey DEV community! 👋 Like many of you, I've been heavily experimenting with AI Agents recently. But as a software architect who hates unnecessary overhead, watching the community default to spinning up heavy Vector DBs and complex graph frameworks just to store conversation context felt like massive over-engineering. We often use massive systems to solve small problems. I wanted an AI memory sys...

Error Budget Policies That Hold Leadership Accountable

Error budgets are useless without a policy. 'We're out of error budget' should trigger consequences. If it doesn't, you don't have an error budget — you have a vanity metric. Here's a policy that actually works. The four states Healthy (< 70% of budget used). Business as usual. Feature development proceeds at full speed. Watch (70-90% used). Feature velocity continues but new risk...

Instrument a Node.js App with OpenTelemetry in an Afternoon

You can get real distributed traces out of a Node.js service in an afternoon, and you should start with the zero-code auto-instrumentation before you write a single span by hand. The fast path is: install @opentelemetry/sdk-node plus the auto-instrumentations package, point an OTLP exporter at a collector or a backend, and launch your app with one extra --require flag. Custom spans come later, onl...

In the Infrastructure Lifecycle Management we can identify the functions of: Provisioning and Decommissioning. Both are orchestrated through the application of Infrastructure as Code (IaC) principles, ensuring that the entire asset lifecycle, from initial resource creation/configuration to the secure, verifiable removal of all components, is managed with consistency, auditability, and minimal o...

Mi primer intento con agentes de IA fracasó. El problema no era el modelo

Hace un año arranqué un piloto, con el respaldo de la empresa, para construir herramientas autónomas de IA sobre el trabajo de desarrollo. Un año después, dos desarrolladores del equipo entregaron el doble de los puntos que habían comprometido en un sprint — y el aumento no dependió de su seniority. Entre esas dos cosas hubo un fracaso completo. Empiezo por ahí, porque es la parte que nadie cuen...

AI Agents Are Distributed Systems in Disguise: The Advanced Mathematics, Color Architecture, and Engineering of Production Agentic Systems

AI Agents Are Distributed Systems in Disguise: The Advanced Mathematics, Color Architecture, and Engineering of Production Agentic Systems Let’s skip the surface-level marketing hype. We’ve all seen basic terminal demos: an LLM receives a prompt, calls a search tool, executes a shell script, and someone tweets about "AGI". Then you attempt to deploy that architecture to handle real pro...

Postgres Full-Text Search in Production: How to Load-Test the Index and Pin Down Relevance

Adding full-text search to Postgres is a two-line migration. Running it in production without surprises is not. The GIN index that makes search fast also adds write amplification and a background cleanup process that can quietly fall behind under a heavy insert rate, and "relevance" that looked fine on your laptop can drift the day someone changes a dictionary. Before you decide Postgres search is...

How I built BrawlerStats: honest trophy history with Firebase and Cloud Run

BrawlerStats started with a simple question: if a Brawl Stars profile is public, why is it still difficult to understand how a player is progressing over time? I built BrawlerStats as a free, no-login companion for public Brawl Stars data. You can search a public player tag, review trophies and brawler progress, inspect recent tracked battles, open public club rosters, and create daily trophy rac...

Your AI Agent Works in Dev. It Will Fail in Production. Here's the Math.

Your AI agent passes every test. It handles edge cases. You demo it to your team and everyone nods. Then you deploy it. And it breaks. Not a little. Catastrophically. The kind of break where you stare at logs for three hours wondering what went wrong, only to discover your RAG pipeline silently returned the wrong chunk 40% of the time. You're not alone. RAND Corporation found that 80-90% of AI ...

Claude Code Can't Draw — This Plugin Borrows Your Codex CLI Login

TL;DR: "Claude can't draw" is a budget problem, not a capability problem. codex-bridge (MIT) is a Claude Code plugin that routes image generation (gpt-image-2) and five GPT-5 subagents through the Codex CLI login you already have — billing against your ChatGPT plan instead of a second API key. I have not tested or run it; this is a source-reading review. How it works. Two bash wrappers shell out ...

Architecting Battery-Efficient Geofencing for Android Automation

It happened during a quiet afternoon at the community library. I was deep in a focused work session when my phone decided it was the perfect moment to blast a loud, jarring ringtone. Every head in the room turned toward me. The embarrassment was immediate and sharp. I had forgotten to silence my device after leaving a noisy cafe, and that one oversight destroyed my flow and disrupted everyone else...

Structured Context vs Pixel Context: What Coding Agents Actually Need

Context is becoming the bottleneck in AI-assisted development. Not model capability — models are improving fast enough that they're regularly not the constraint. What limits the quality of AI-generated code is the quality of context those models receive. For Figma-to-code workflows, context comes in two fundamentally different forms: pixel context (screenshots, rendered images) and structured con...
