Juillet-Août 2023

Bonjour, voici les nouvelles de la rentrée. N’oubliez pas le café Julia le 15 septembre à 10:00 et les Journées Julia et Optimisation du 4 au 6 octobre au CNAM Paris.

La France passe troisième au nombre d’utilisateurs derrière l’Allemagne et les Etats-Unis d’après les résultats du sondage annuel réalisé pour JuliaCon.

Julia est entré dans le top 20 du TIOBE Index qui classe les langages de programmation par popularité.

Il y a maintenant une centaine de nouveaux packages par mois donc vous ne voyez ici qu’une sélection personnelle. N’hésitez-pas à m’envoyer vos liens ou vous pouvez faire directement une PR sur pnavaro/NouvellesJulia.

Une information importante a été publiée cet été à propos de l’utilisation des threads. Je conseille vivement de lire cet article:

PSA: Thread-local state is no longer recommended
