Bruce Springsteen - Streets Of Minneapolis (Official Audio)
Bruce Springsteen - Streets Of Minneapolis (Official Audio) YouTube video by Bruce Springsteen

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Du sang français a coulé, et qu'a fait Nicolas Sarkozy, M. Thréard ? Il a envoyé ses deux lieutenants pour négocier avec un terroriste, condamné à perpétuité pour avoir tué 54 Français.

C'est un crime contre la Nation.
C'est la patrie qu'il a trahie.

I would say I will always prefer Flutter over MAUI if I have full control of the implementation.

Je ne sais pas si tout le monde réalise le niveau d'incompétence qu'il faut atteindre pour :
- Couper dans le budget de la recherche universitaire,
- Et engager un budget dans une campagne de pub pour la recherche,
EN MÊME TEMPS (et sans rougir).

Macron vient d'annoncer que supprimer des programmes de recherches aux Etats-Unis était une erreur et ouvre le programme "Choose Europe for Science" en investissant 100 millions
Il y a une semaine, le gouvernement annonçait couper 493 millions de crédits pour la recherche et l'enseignement supérieur

Thank you so much @mauiday.net for this magnificent event! It felt like it was the first time all over again. I could feel the kindness in the room. I don’t really enjoy swags but this was the best swag I’ve ever received: human words written by human hands. Thank you.

Bel exploit de @franceinter.fr : organiser un débat sur l'enseignement de l'histoire en France avec...
...un historien non universitaire, non enseignant
...un journaliste du Figaro nostalgique de son enfance
Aucun n'ayant la moindre idée des réalités
Quelle honte !
