Intéressant, j'adore l'idée de collaborer et réutiliser les SKILLS. J'ai l'impression que des projets comme Tessl, un paquet manager de skills, vont être intéressants à tester

Beyond the API: Integrating ComfyUI and Flowise via MCP 🤖🎨

I just published a guide on moving from brittle API integrations to the new Model Context Protocol (MCP) standard. See how to build a chat agent that handles image generation and editing autonomously.

A Software Library with No Code Do we still need libraries of 3rd party code when AI agents are this good?

It is for a very simple use case but this is food for thought...

Vibe Coding scripts is easy. But how do you Vibe Code a system?

In Part 3, I explore Governance-Driven Development. By using Architecture Decision Records and AIOps to guide the AI Developer, we built a modular monolith, one vertical slice at a time.

Can you "vibe code" a UI? 🤔

In Part 2 of our series, we're building a browser-based Yoga Pose Builder from scratch with no stack and no design, using AI.

Read how we went from a blank folder to a functional SVG editor in one session (link in comment).

Ever heard of "Vibe Coding"? It’s intent-driven development. You act like a conductor, not a bricklayer.

I’m starting a new series on it! First up: Building a smart magazine archiver (turning web images into a searchable PDF).

The LLM inference landscape is exploding.

Should you use the data center standard #vLLM, local favorite #Ollama or the radical newcomer #ZML?
I applied the rigorous #QSOS method to compare these engines on features, performance and operational ease.

M'en parle pas, je regrette d'avoir développé mes propres extensions WP de ouf. Les dix premières années c'est sympa et gratifiant, désormais je cherche juste assez de motivation pour tout migrer en statique

I delivered my two talks yesterday at #osxp Open Source Experience. This event has a special place in my heart since I started public speaking in its ancestor (Solution Linux) 20 years ago!
