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
Generative AI is no longer just an emerging technology. It is becoming a core business capability across software development, customer support, analytics, content generation, automation, knowledge management, and enterprise productivity.

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

Elle pivote sur sa chaise et me lance depuis son bureau : « Michel, combien on a d'inscrits pour la rentrée, d

Cup in hand, the one with her face printed on it that someone gave her at Christmas. She swivels in her chair and calls over from
Building a Translation Pipeline for International Contract Bidding If your company bids on international contracts, you've probably dealt with the translation bottleneck. Technical proposals need precise translation, certified documents have strict formatting requirements, and procurement deadlines don't wait for anyone. After seeing how UK public procurement translation requirements can make or
Inside the five-stage pipeline from 1.1.1, there is another fork right after the parser. PostgreSQL classifies every SQL command into one of two camps. One side holds the optimizable queries, the other holds the utility commands. The classification is decided by a single field on the Query node, commandType, and from that point on the two camps travel completely different paths. One goes through t
