We Used to Call It a Write-Off
A 2013 Cegid, an Odoo 11, a home-grown PHP app, a WordPress site infected twice over. The experts' verdict never changed. With Claude Code, it has.

Never Tell Them the Answer
I started running Advanced Dungeons & Dragons at fourteen, in a village youth club in the Yvelines, with three hardbacks in a language I did not have yet. It turned out to be the only facilitation training I ever received.
Twenty Years of Cleaning Bugs
The Sunday-morning call has not changed in twenty years. Only the bug has: from a crash, to a configuration, to a sentence that is fluent, confident and wrong.
Choose Number Five
In 1965 Edith Sampson handed a graduating class one last multiple-choice exam: five ways to spend a life. Four of them are still available in 2026, and the feed has made them easier than ever.
Standing Watch
A daily security watch that runs itself: a swarm of local agents, a Kanban board, and a background task wired into a one-person SOC. A Vibe Orchestration field report.
Effectuation, Twenty-Five Years Later
I read Sarasvathy's paper in 2001, while the dot-com crash was eating my first company. Four ventures later, an accounting of what held.
Hermes Agent on Mac: a local-first setup with two profiles, A (local) and B (cloud)
A sovereign, local-first AI assistant on Apple Silicon for sensitive data, plus a high-performance cloud mode when the task earns it. Two isolated Hermes profiles, one toggle.
Deploying GenAI Without Breaking GDPR
A leader freezes a working AI project out of fear of GDPR and the AI Act. The three texts are not three walls. They ask, in three vocabularies, the same four operational questions.
The Marble Was Never Sacred
A morning at the Panthéon, a chronology of erasures, and what a façade actually owes the people who read it.
The Boring Stack
SQLite, Markdown files, Python standard library. After a quarter-century in the trade, why the most experienced CIOs are also the hardest to impress.
The Tax Labyrinth
Five portals, three login systems, one self-employed citizen. France's tax infrastructure is not buggy. It is obsolete by design. Field notes on the cost.
Prompts Are Dead, Long Live Direction
The prompt engineering era is over. What replaces it isn't a better prompt. It's the room the prompt sits inside.
The Geek Code, Decoded
A 1993 Usenet signature standard, dusted off and read back as identity in 2026.
Fear vs Love at Work
Love and fear cannot share the same room at full intensity. A short note on what that means for leading a company.
The Expert's Paradox
If you need to be an expert to verify what the AI says, you don't need the AI. The paradox that quietly defines AI use in 2026.
Nineteen Years Inside a Sociocratic SMB
Five years in, I realised I was the bottleneck of my own company. This is what changed when I got out of the way.
Sovereign by Default
An SMB's first sovereignty question is not where the data is hosted. It is whether the company can still operate on Monday if the vendor disappears on Friday.
The €300 Subscription Tax
Forty-six recurring charges on one bank statement, fifteen people on the payroll. Cold accounting of an SMB stack, and the 80-line Python script that quietly replaces half of it.
When the Room Empties
The share of genuine human content on the live web is shrinking faster than most organisations realise. What a CIO actually sees in logs, pipelines, and API traces, and why it matters for everything downstream.
The Slow Feed
RSS never died. It just stopped being interesting to anyone trying to monetize your attention. That is precisely the point.
Why I Build on Astro
A field report after a few weeks on Astro v6. What worked, what bit me, why it fits the Small Web.
Algorithmic Slop
Confident, well-formatted, quietly wrong. Five real cases from a fractional-CIO practice, and the discipline that catches them.
Vibe Orchestration
Most people chat with AI. A few direct it. What changes when you stop being an operator and start conducting.
Author, Not Product
I deleted my LinkedIn, MALT and APEC accounts this morning. This site is what I built instead.

Adjacent Possibles
How a hexagonal floor tile became a way of choosing what comes next.

Qui formera les experts de demain ?
AIFR
Le travail confié aux juniors ne servait pas qu’à produire, il les formait. Si l’IA le reprend sans qu’on y pense, on leur retire de quoi apprendre le métier.
Le tenant que personne ne possède
Quatre-vingt-dix licences payées pour soixante salariés : je retrouve cet écart dans chaque audit Microsoft 365, et personne dans l’entreprise n’a pour travail de le regarder.
NIS2 : la date n’est pas le sujet
La loi de transposition attend son passage à l’Assemblée depuis un an, la France est devant la Cour de justice, et l’ANSSI a déjà publié les vingt objectifs de sécurité. Ce qui manque, c’est le vote, pas les exigences.
Notes de lecture : Faber à HEC
Dix ans après le discours, ce qui reste, c’est surtout ce qui s’est passé ensuite, et ce que ça dit d’une intention qu’aucun statut ne protège.
Scop et Scic : un système porteur, pas une opinion politique
Le statut coopératif décide qui vote, qui détient et ce qui ne peut pas sortir. Ce sont des choix d’architecture, au même titre qu’un schéma d’infrastructure.
RAG sans illusions
AIFR
Ce que coûte vraiment un RAG en PME, et pourquoi la plupart des projets qui en demandent un ont besoin de cinq documents et d’un prompt.
Acculturer une équipe à l’IA générative
AIFR
Payer des licences ne suffit pas à installer l’usage. L’adoption de l’IA générative bute surtout sur la peur et la permission floue, bien plus que sur le choix du modèle.
Où héberger son IA ?
AIFR
Le pilote fonctionne. Reste la question que personne n’a posée avant de commencer : où vit le modèle, et de quoi accepte-t-on de dépendre ?
Le DSI qui a cessé de décider
Pourquoi un DSI à temps partagé qui centralise les arbitrages installe le goulot qu’il était censé démonter.
Changer d’ERP : carnet de chantier
Le détail d’un devis d’intégrateur à 300 k€, et comment outils MLOps et gouvernance partagée font fondre le stress qu’on croyait inévitable.
