A follow-up: how the architecture works In my previous article, I explained why I built NGB Platform and what problem it is trying to solve: I Built an Open-Source Platform Foundation for Accounting-Centric Business Apps That article was mostly about the why. Why generic web frameworks are not enough for serious business applications. Why large ERP products solve many of the right problems, but
We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin
Metric Value Django Average Response Time 287ms Node.js Average Response Time 193ms Django Memory Usage (1000 users) 1.8GB We tested Django 4.2 and Node.js 18.16 under identical conditions to measure their performance for reporting dashboard workloads.

War Story: Ditching MongoDB 6 for PostgreSQL 17 Saved Our 50M User App from Data Inconsistencies Our social commerce platform hit 50 million monthly active users in Q3 2024, powering 1.2 million daily transactions across 30 countries. For three years, we’d run on MongoDB 6, lured by its flexible document model and horizontal scaling. But by mid-2024, data inconsistencies were threatening our cor

It is becoming a core business capability across software development, customer support, analytics, content generation, automation, knowledge management, and enterprise productivity. For cloud professionals, developers, data teams, and solution architects, learning Generative AI on AWS is now a high-value career move. AWS provides a growing e
The Model Context Protocol has transformed how we connect AI to tools. But connecting agents to tools is only half the battle — connecting agents to each other is where the real challenge begins. I recently read @raviteja_nekkalapu_'s excellent article "I built an AI security Firewall and made it open source because production apps were leaking SSNs to OpenAI" and it resonated deeply with challeng

Vendredi matin, 9 h 15. Françoise est dans son cockpit — trois écrans, à gauche l'Excel-pointeuse qu'elle tient à jour depuis quinze ans, à droite Sage, et au milieu Rembrandt depuis trois semaines. Sa tasse à la main, celle avec sa tête imprimée dessus que quelqu'un lui a offerte à Noël. Elle pivote sur sa chaise et me lance depuis son bureau : « Michel, combien on a d'inscrits pour la rentrée, d
