How Chrome Extensions Actually Work in 2026 (Manifest V3 Explained)
MV3 is four moving parts, manifest, service worker, content scripts, and UI, not a single script tag anymore.
Personal Page - From Personal Site to Product
Stop presenting projects. Start shipping a system that compounds trust.
Build in public
Journal de build
Ce qui a shipé, ce qui a cassé et ce qui a changé, rédigé au fil de l'eau.
ResistGate 1.3.3, clearer popup, better first glance
Shipped a popup refresh focused on first-glance clarity: the popup now states the job plainly, the current-tab shortcut says exactly what it does, and the empty state lost its duplicate copy. Small release, but every session starts at the popup.
Amethyst 1.6.2, the popup stops trying to be the dashboard
Rebuilt the Amethyst popup around one question: where did today go? It now opens with the daily total, top sites, and a single button into the full dashboard. Removed the tracking badge, comparison chip, sync button, and feedback card, the glance view answers fast, then gets out of the way.
Published the agent-readable portfolio series
A run of notes on making this site readable by AI agents: the MCP server, the public API, the data model, and the security lessons from exposing it all. Personal sites are becoming APIs, this series documents doing it for real.
Ingénierie IA
Comment les fonctionnalités IA se comportent quand de vraies personnes les utilisent, pas dans des démos contrôlées.
Never Send the Image to the Fine-Tuned Model
You fine-tune the voice, not the perception. Perception is a commodity you rent; voice is the thing you cannot buy.
What Actually Breaks When You Put a LoRA Adapter in Production
The expensive failures were not training failures. They were infrastructure failures that produced plausible output instead of an error.

How to Publish a Chrome Extension to the Web Store in 2026 (Full Checklist)
The Web Store review is a product gate, privacy policy, assets, and MV3 compliance matter as much as your code.
How I Built ResistGate: A Chrome Extension That Makes You Earn Distractions
Real products need friction by design, ResistGate makes you type before distraction, not just block URLs.
Décisions produit
Tarifs, choix produit et ce que j'ai appris en essayant de créer des choses que les gens achètent vraiment.
What Loot Boxes and Battle Passes Teach Every Builder
Game monetization splits cleanly into predictable-and-fair and random-and-manipulative. Regulators are banning the second, and the same line runs through how any product charges.
Subscription Fatigue and the Real Cost of Dark Patterns
Retention won through dark patterns is debt. It builds regulatory and reputational liability and makes every future price increase impossible.
Conception de systèmes
Compromis d'architecture, primitives plutôt que complexité et modèles de systèmes durables.
Server Authority Without a Sluggish Interface
Predict locally, decide centrally, and make rejection a first-class state.
A WebSocket Connection Is Not a Real-Time Architecture
The transport moves messages. Your protocol decides whether the product stays coherent.

Comment je prends des décisions, reste concentré et avance sans équipe.
Ten users and a five-star rating
You can't skip the ten. Every million starts as ten people who actually stayed.
Ten Questions Before You Pick a Business Model
The right model is the one your product's costs, users, and habits actually point to, not the trendy one. Ten questions get you there.
