Hier soir en allant faire des courses, des touristes prenaient le soleil en photo, pensant que c'était une éclipse de lune 😅 (Et dans la soirée et ce matin, c'était proprement irrespirable... Je suis à ~70 km au nord de Bordeaux...)

Y a pas besoin d'attendre les données post-flight pour voir que les Raptors sont toujours tout sauf fiable 🤷
Screenshot d'une partie de l'écran la vidéo youtube de Reves d'Espace rediffusant l'amerrissage du booster SuperHeavy. On y voit deux indications de la télémétrie: le nombre de moteurs en marche et l'altitude. à 100 mètres de l'amerrissage, le booster n'a que 5 moteur en route, 2 au centre, 3 sur la couronne interne, dont la répartition semble indiquer un dysfonctionnement

Yep, c'est précisément dans le sens premier du mot que je l'ai utilisé 😉

Pour le fun et sans ordre particulier
Mosaïque de 9 des jeux qui m'ont marqué pour une raison ou une autre. De gauche à droite et haut en bas:
- Zelda Ocarina of Time (premier Zelda que j'ai possédé, mais bien d'autres de la série auraient eu leur place sur cette matrice)
 - Fallout 2 (la liberté offerte m'avait mis une claque a l'époque... Ainsi que ses innombrables bugs 🤣)
 - Outcast (malgré une histoire somme toute convenue, la claque graphique et musicale, la liberté, la richesse du monde... Et les années a contempler le CD, incapable de faire tourner le moteur voxel du jeu de manière non saccadé sur un ordi "normal" 😅)
 - Super Metroid (encore une claque par la richesse de son contenu)
 - Syberia (une atmosphère incomparable, un monde très émouvant et des personnages extraordinairement attachants. Le 1 vaut pour toute la série)
 - Screamer 2 (simplement pour le nombre de courses qu'on s'est fait avec un pote, au point de connaître tous les moindre bugs des circuits qui permettaient de passer devant l'autre)
 - MDK (entre claque graphique et de gameplay, personnages haut en couleurs et ne se prenant pas du tout au sérieux)
 - Worms Armageddon (un nombre de parties entre potes incalculables)
 - I-War (une autre claque graphique mêlée à une physique "réaliste" des combats spacieux avec histoire riche)

Mentions spéciales que j'ai vraiment hésité à mettre: Mario (pet') Party pour le nombre de soirées entre amis, Silent Hill 1 et Résident Evil 1 pour ma découverte du Survival horror, Grim Fandango pour le summum de la grande époque des point'n'click LucasArts

Fisheye photo of a massive green and red curtain of aurora taken from a pier next to a fjord. The pier can be seen in the lower right corner with some people on it and few trees to the right. The fjord and the land on the other side can be seen on the lower left part of the picture. Finally the aurora appears like a massive mountain of light rising from the sea to, almost, the top of the picture. It presents shades of green and yellow on its lower part, with the majority in bright to deep red. Finally, of strong reflection of the aurora appears on the sea in a curved lower band in the pic.
