Last Tuesday I lost about three hours to a regression in our checkout service. The cart total was off by a cent on certain promo combinations, and the only signal was a Slack ping from finance with a screenshot. No stack trace. No exception. Just wrong numbers. I did what I always do first. I opened the diff for the last deploy, scrolled, squinted, and tried to feel my way to the bug. Forty minute
L'IA vocale en gestion de chantier : retour d'expérience après 50 projets BTP Le problème : les mains pleines, le temps compté Sur un chantier, le chef de projet ou l'artisan a les mains occupées. Qu'il soit en train de mesurer une façade, de vérifier l'aplomb d'une cloison ou de valider du béton fraîchement coulé, la dernière chose dont il a besoin est de sortir son téléphone pour re
In 2024, 72% of production RAG systems fail to meet p99 latency SLAs of 500ms, per a Gartner study of 1200 enterprise deployments. The root cause? 89% of teams misconfigure vector database integration with orchestration frameworks like LlamaIndex. This deep dive fixes that, with benchmark-backed code and architectural walkthroughs. Humanoid Robot Actuators: The Complete Engineering Guide (49 poi
If you have ever run DESCRIBE HISTORY on a Delta table that receives streaming data every 60 seconds and watched it either hang for hours or crash with an OutOfMemoryError, you are not alone and you are not doing anything wrong. The problem is architectural, and once you understand the internals, the fix becomes a lot clearer. Here is what I learned after digging into why this happens and what you
This is the follow-up to What I Actually Learned Building a Side Project in 5 Days With AI. That post was about AI. This one is about what happens after you ship — when you actually have to run the thing. I lost a freelance client last year because I forgot to send a monthly report. Not because I didn't do the work. I did the work. I just never wrote it down in a place I'd actually look. The repor
The problem nobody warned me about Same prompts. Same workflows. Same model. Higher bill — every single week. No input change. No structural change. Just more tokens — and a cost bill I could not explain. What changed under the hood Three things shifted simultaneously, and most cost-increase explanations only mention one of them. 1. The tokenizer itself changed Claude's tokenizer now splits text d
Physics has always been one of those subjects that feels like a maze of invisible forces and abstract variables. To make learning more intuitive, I recently launched Physics AI Slover, a specialized platform designed to provide step-by-step solutions and visual derivations for students struggling with mechanics, electromagnetism, and thermodynamics. Solver Mode is for that 2 AM panic when you ju
In Q3 2024, 72% of production RAG pipelines failed to meet p99 latency SLAs for multimodal queries, according to a Datadog survey of 1,200 engineering teams. Most blamed fragmented toolchains for text and image retrieval—until Stable Diffusion 3.0’s embedding API and Llama 4’s 1M-token context window changed the game. This is the definitive guide to building unified multimodal RAG pipelines that c
