fascinant de voir comment il n'y a pas de débat ici (contrairement à X) sur la présentation pour le moins douteuse des chiffres des taux des prélèvements utilisés dans la défense de la taxe Zucman

Apparemment ma députée, @sandrousseau.bsky.social, MCF en économie, raconte que Smith (1723-1790) et Ricardo (1772-1823) ont été influencés par Darwin (1809-1882) pour leur conception libérale, capitaliste et donc darwiniste de l'économie. 🤷

Triste por la partida de un maestro, quizá el más grande novelista en español, y sin duda uno de los ensayistas con la pluma más acerada.

Mario Vargas Llosa, Prix Nobel de littérature et auteur de « La Tante Julia et le scribouillard », est mort
L’écrivain d’origine péruvienne est mort à 89 ans, dimanche, à Lima (Pérou). Chef de file des auteurs latino-américains, il considérait la littérature comme un moyen d’éveiller les consciences.

Funny to think about this having watched PL Lions say "qui cherche trouve, et qui recherche retrouve", which means basically that in research you rediscover a lot of things. It reminds me of one of my favourite papers during my PhD.

Nice bit of cross-venue arbitrage where you can log on to Twitter and call the OpenAI people lazy money-burning pump artists and fight with them, and then when that gets boring you can come to Bluesky and call the anti-AI people innumerate luddites and fight with them for a change instead.
