We wrote an open letter (in French) to protest against France's renewal of their Elsevier subscription for 4 more years:

France's subscription consortium Couperin will again sign for 4 years with scientific publisher Elsevier, continuing to support a system where scientific research is locked behind a paywall https://www.soundofscience.fr/1754

L'ensemble vocal dont je fais partie (l'ensemble vide) monte un spectacle à l'interface entre opéras baroques français (Charpentier, Lully, Rameau) et émissions de télé-réalité (aux Enfers, si si). On a des dates de concert à Paris (3-4 avril, 18-19 et 23 mai), vous pouvez venir nous voir, et vous pouvez aussi nous aider à financer ces spectacles ! :)

Un groupe de gens veut faire un Secret Santa mais où chacun donnera un cadeau à un de ses "amis" : étant donné le graphe des amitiés, on veut calculer si c'est possible ?

Si on demande un seul "cycle" de cadeaux alors c'est NP-dur (= Hamiltonian cycle), mais si on en permet plusieurs alors c'est PTIME (= vertex-disjoint cycle cover).

À présent, si on interdit les échanges entre 2 amis mutuels, alors ça reste PTIME si le graphe d'amitiés est non-orienté mais ça devient NP-dur s'il est orienté !

Nice writeup about the shortest superpermutation problem https://www.quantamagazine.org/sci-fi-writer-greg-egan-and-anonymous-math-whiz-advance-permutation-problem-20181105/ for which progress has come from outside academia. It's nice also to see ongoing efforts to solve the problem https://groups.google.com/forum/?nomobile=true#!forum/superpermutators
