TIMELAPSE OF THE ENTIRE UNIVERSE - YouTube
« Sur une échelle de temps cosmique, l'histoire humaine est aussi brève qu'un clin d'œil. En comprimant les 13,8 milliards d'années du temps sur une durée de 10 minutes, cette vidéo montre à quel point nous sommes jeunes, et à quel point notre univers est ancien et vaste. Commençant par le Big Bang et culminant avec l'apparition de l'homo sapiens, cette expérience suit l'écoulement du temps à raison de 22 millions d'années par seconde, en adhérant étroitement à la compréhension scientifique actuelle. »Tue 20 Apr 2021 09:53:47 PM CEST - permalink -- https://www.youtube.com/watch?v=TBikbn5XJhg

XOR has good properties, is it the only one? - Sbgodin
Je me suis demandé s'il existait une fonction binaire autre que XOR pour faire de la cryptographie. XOR est utilisée dans de nombreux cryptosystèmes du fait de ses propriétés intéressantes. Un programme Python m'a fourni la réponse : le XNOR marche également, et c'est tout.Tue 19 Dec 2017 11:46:42 PM CET - permalink -- https://blog.sbgodin.fr/article8/xor-has-good-properties-is-it-the-only-one
