Anthropic a lancé Claude Fable 5 hier, et je veux être prudent sur la façon dont j’en parle, car la ferveur marketing entourant les lancements de modèles est désormais fixée en permanence sur « cela change tout ». La plupart du temps, ce n’est pas le cas. Celui-ci a plus de chances d’avoir une réelle importance, et pas entièrement pour les raisons mises en avant dans l’article de…

Anthropic shipped Claude Fable 5 yesterday, and I want to be careful about how I talk about it, because the marketing temperature on model launches is now permanently set to “this changes everything.” Most of the time it doesn’t. This one is closer to actually mattering, and not entirely for the reasons the launch post leads with. Here is the short version for busy people: Fable 5 is the first…

1. Introduction: The Post-Launch Reality Check In the hyper-accelerated cadence of the AI industry, “new” is beginning to feel synonymous with “incremental.” With Claude Opus 4.7 having arrived only a month prior, many developers initially greeted the May 28, 2026, release of Claude Opus 4.8 with a measure of release fatigue. At first glance, another flagship update so soon feels like a…

A complete step-by-step tutorial on Andrej Karpathy’s LLM Wiki method Karpathy’s LLM Wiki gist on GitHub has been starred over 5,000 times and forked just as many. Most of those people will never actually build the thing. This tutorial exists for the people who will. Original reference: https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f Why this isn’t another RAG tutorial When…

1. The Paradigm Shift: From Chatbot to Senior Teammate Deprecate the “chatbot” mental model in favor of the stateful runtime primitive. In high-performance engineering environments, viewing Claude Code as a conversational assistant is a Level 1 bottleneck. To achieve Level 4 architectural maturity, you must treat Claude Code as a comprehensive agent development kit (ADK) capable of executing…

The “Spud” Has Landed: Beyond the Poem The AI “jagged frontier” just moved again, and this time it didn’t come with a flashy keynote. OpenAI surprise-dropped GPT-5.5 (codenamed “Spud”), and the technical community is scrambling to figure out if this is a true step-change or just another incremental polish. I’ve spent the last two hours ignoring the hype to focus on the signal. We are officially…

It’s 11 AM and Claude just told you to come back later. You’re mid-draft on a client deliverable, or halfway through debugging a function that was almost working. Sound familiar? Here’s the thing: the limit isn’t the problem. Your habits are. Most people default to the biggest model for everything, leave token-hungry features running in the background, and treat every chat like a never-ending…

From Code to Weights to Prompts: A Practitioner’s Guide to Software 3.0 By Sami BELHADJ Introduction: The Machine Is Finally Listening In the past three years, software development has hit an inflection point unlike anything the industry has seen since the transition from mainframes to personal computing. Large language models have exploded in popularity at a pace that caught even their…

Analyse des impacts à court, moyen et long terme du durcissement des conditions de financement des importations non prioritaires Analyse consolidée — 4 avril 2026 sur https://tech-tech.life  Par Sami Belhadj (https://www.linkedin.com/in/sbelhadj) Résumé exécutif La circulaire aux intermédiaires agréés n°2026-4 du 26 mars 2026 de la Banque Centrale de Tunisie (BCT) impose un changement radical…

1. The Perpetual Gap: The Documentation Tax We have long suffered the “Documentation Tax”—that inevitable decay where the Product Requirements Document (PRD) becomes a tombstone for original intent the moment the first line of code is written. In the traditional cycle, we treat specifications as “discarded scaffolding”: temporary structures used to erect the “real” building (the code) and then…

1. Introduction : Le “Code est Roi” est mort Pendant des décennies, l’ingénierie logicielle a vécu sous un dogme immuable : le code est la vérité absolue. Tout le reste — documents d’exigences, schémas d’architecture, commentaires — n’était que littérature, souvent obsolète avant même d’être lu. Nous avons accepté ce fossé entre l’intention humaine et l’implémentation machine comme une fatalité…

L’illusion de l’assistant : Invalider les postulats de la gouvernance logicielle Nous vivons un paradoxe structurel. La majorité des organisations traitent l’intelligence artificielle comme une simple extension de leurs outils existants — un assistant de saisie ou un générateur de documentation plus performant. Pourtant, l’IA n’est pas une simple accélération de l’existant ; elle invalide les…

For decades, the Software Development Life Cycle (SDLC) has operated with a familiar, predictable rhythm. Product managers dictate requirements, engineers write the code, and QA teams test the result. This was a deterministic system designed for a world of static logic where identical inputs yielded identical outputs. That era is over. We are currently trapped in a “Deterministic Delusion.” The…

Il y a des livres qu’on referme en se disant « c’était bien ». Et puis il y a ceux qu’on referme avec une sueur froide, en se demandant si ce qu’on vient de lire ne se joue pas, quelque part, en ce moment même, dans une salle de réunion feutrée dont on ignore l’existence. Jackson Hole appartient à cette seconde catégorie — et nous ne nous y attendions pas du tout. Nous le disons d’emblée : aucun…

Top AI Tools Boosting Productivity Across 12 Professional Fields Artificial intelligence (AI) has become a driving force behind productivity gains in nearly every domain of work. Generative AI in particular is expected to automate 60–70% of routine tasks, potentially raising labor productivity by an estimated 0.5%–3.4% annually by 2040. In this context, experts have identified over 100…

L’Inversion du Paradigme de Diffusion Technologique : L’IA Générative comme Vecteur d’Émancipation Individuelle et Défi de Souveraineté Organisationnelle La trajectoire historique des technologies de rupture a longtemps obéi à un schéma de diffusion descendante, où l’innovation, initialement confinée à des domaines régaliens, militaires ou de recherche fondamentale, finit par percoler vers le…
