I am very interested in metadata and model-driven architecture (usually found in code generators, low-code platforms, and data visualization). I experiment with my open-source project Evolutility model-driven UI and backend, as well as other side-projects.
My favorite quote about programming is "Smart data structures and dumb code works a lot better than the other way around." - Eric S. Raymond in The Cathedral and the Bazaar.
I sometimes experiment with salty madeleines. Salty madeleines with duck prosciutto are really good, but I still prefer the sweet madeleines with lemon zest and pine nuts.
I'm learning to make cannelés. They are good but it may take a few more trials for the perfect consistency.
I also like visual art made by humans... and it often contains fractals or the golden number.
Sometimes I try things like carving a book.
I like to read and collect graphic novels, mostly sci-fi and fantasy, usually in French.
... and sometimes in English.
I like to watch sci-fi movies and anime but I do not own a TV.
Of course, I also enjoy French movies.
I like to meditate and to make Chakras charms.
I'm (slowly) learning to play the handpan.
