I'm completely out of touch with how other people think... but maybe it could be easily fixed by reading other people's conversations with AI chatbots. Have you done this and was it illuminating?

Tentative design guideline: when things get complicated, avoid extra abstraction layers that don't introduce a beneficial separation of concerns.

I quit the consumption of all passive feeds of information a few days ago. My motivation and productivity are back to healthy levels.
I used to actively ignore ads in contexts where there's no ad blocker and it was working fine. Now I do the same for all Bluesky, LinkedIn posts, YouTube home, etc.

AI isn't turning the programmer's brain into mush. It's just that we're now acting more like managers. Oh wait.

Le 1er mai en France, tout le monde a le droit de travailler. Ce qui est interdit c'est d'employer des gens. Ce n'est pas du tout pareil. Travaillez pour vous-mêmes, camarades.
Qui a le droit de travailler le 1er-Mai ?
Qui a le droit de travailler le 1er-Mai ?
Le 1er-Mai a occupé cette année le devant de la scène bien en amont de la journée des travailleurs, pour cause de débats sur un possible élargissement des possibilités de faire travailler des salariés ce jour-là. Rappel des règles en vigueur et ce qui pourrait changer.

I genuinely believe that to be trusted, an AI system must be wired to not want to die.
I wonder at what point in history my smartphone OS will become self-aware and will start taking care of itself so that it doesn't die and I'm not tempted to kill it either.

If you're pondering whether you should have kids, the answer is probably yes. We're wired to raise kids. Some people like kids more than others but overall, I think it's easier than the average guy would expect. Also, they're your kids; they're much more interesting than other people's kids.

I've created a complete, pure-OCaml YAML library called YAMLx (Yumyulack was too long). It will be suitable for reading config files in your applications as well as for analyzing YAML files used by other projects.
Aiming for a release by the end of this week.
