L’article “décompile” la chaîne et nous explique chaque morceau : Le début de la chaîne correspond à un shebang. Une partie de cette “introduction” permet de dire quand il faut commencer le boulot, combien il faut produire, etc. L’équipe qui a conçu le vaccin y a collé une instruction tirée d’un gène puis optimisée qui permet de dire « commence à produire maintenant ! » Les nucléotides “U” sont remplacés par une version légèrement modifiée (1-méthyl-3'-pseudouridylyle) : interprétée comme U par le ribosome, mais permet à l’ARN de ne pas être détecté par le système immunitaire. Truc de ouf : le hack qui permet d’accélérer la production : maximiser le nombre de C et de G. (plusieurs codons codent le même acide aminé, autant prendre les plus rapides à traduire.) Quelques hacks dans le corps pour maintenir Spike dans la bonne forme. https://twitter.com/nandoodles/status/1345774768746852353 Fraude à la pub Uber https://news.slashdot.org/story/21/01/05/1929229/81000-uk-owned-eu-domains-suspended-as-brexit-transition-ends Les britanniques ont “perdu” leurs domaines en .eu. (Suspendus) https://eurid.eu/en/welcome-to-eurid/corporate-governance/ Le Kernel https://kernelnewbies.org/LinuxChanges Linux 5.10 was released on Sun, 13 December 2020. https://lkml.org/lkml/2020/12/13/290 LTS => longer maintenance ext4 fast commit (needs to be enabled at mkfs) -> optimized metadata writes on fsync (journal) Btrfs => better perf for fsync => better use of standard features of the kernel: iomap (direct mapping of kernel io page to process memory map), start switching from custom locks to standard rwsem io_uring restrictions (acl for ring sharing) process_madvise => madvise from a daemon for another process (w/ pidfd) shared host/guest fs cache in virtiofs => less memory consumption => faster Static_call (retpoline alternative for spectre mitigation) => instead of going through global function pointers, code patching to directly call the destination function code, ~inlining. Basically, eager autoderef of fn ptr once instead of at each call => same as static_branch, but for indirect fn calls Nonblocking pidfd (incompatible w/ wait) Deadlock detection for recursive read locks Kcsan: support for compounded rw (e.g. writes and reads that are not atomic) Printk optim w/ lockless ringbuffer and no more tmp cpu buffers BPF sleepable progs BONUS: crypto: more work inspired by zinc (wireguard) towards libcrypto cleaner primitives out of crypto + better formally proven and/or battle tested impls Io_uring: wait sur la consommation d’évènements au lieu de busy polling (être prévnu quand on peut ajouter de nouveaux éléments parce que la queue était pleine) https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/co...
