I just came back from a two weeks vacation in France with my daughter, and without my laptop, which was pretty nice. As a result I don’t have much to say for this month !
After coming back I had an idea for a small project, a “guess who” app that I vibecoded in a few hours with Firebase Studio. It got me a Next.js+tailwindcss app pretty quickly, with LLM calls handled by Genkit. Originally it was using the Gemini API and hosted on Firebase, but I’ve changed it to GPT-5 and Fly.io for hosting.
I haven’t looked much at the code actually, but the LLM part of it seems clean and use Genkit flows, and the app works well enough that I call it a success ! I’m not quite ready to release (mostly I need to put some kind of spending limit on the API token). It’s so strange that the main LLM providers don’t allow setting a maximum spending limit on a given API token already. I’m not going to risk spending thousands on a stupid app in case it might go viral !
Oh, and I migrated my blog from Jekyll to Hugo. No special reason for the change, these days I’m much more into Go than Ruby, and it was pretty painless with the Import command. I still have to fix some links.
To finish with, a cool picture of my home viewed from the plane, on the way back !
