Python CQRS: Building distributed systems without the pain (Sagas, Outbox, Event-Driven)

Building distributed systems in Python? Here is how python-cqrs tackles consistency with orchestrated sagas, the mediator pattern, and a transactional outbox—without preaching theory for ten pages first.

When an API Key Lives in Local Storage: A Subtle but Risky Pattern

While testing a production web application, I noticed a third-party API key (used for consent and privacy management) stored directly in the browser’s localStorage. It’s a common pattern in modern frontends—but one that can quietly expand your attack surface. This post breaks down why it matters, how it can be abused in real scenarios, and what both developers and bug hunters should look for. ...

De ticket a deploy sin tocar nada: cómo Claude Code orquesta mi flujo entero

Lunes por la mañana. Abro Timeview — mi gestor de tareas — y hay un ticket nuevo: migrar un listado de scroll virtual a paginación tradicional. Hace unos meses, este momento significaba 10 o 15 minutos de fricción antes de poder siquiera pensar en el cambio. Copiar el título, crear la issue en GitLab, etiquetarla, asignarla, crear la rama, abrir el MR en draft, hacer checkout, abrir VSCode. Secret...

10 Chunking Strategies That Make or Break Your RAG Pipeline

A 2025 peer-reviewed study (Vectara, NAACL 2025) found something most RAG teams get backwards: Chunking strategy has equal or greater impact on retrieval quality than embedding model selection. Teams spend weeks choosing between OpenAI, Cohere, and Jina embeddings — then split documents every 512 tokens and call it done. The data says that's the wrong priority. I tested 10 chunking strategies ag...
