Replying to @b0rk
Hijacking to push my deck of "bash production guide" (slideshare.net/Saruspete/bas…) and many lesser-known tips, like: PS4 & set -x set -o nounset -o noclobber bash / ksh diff [ vs [[ braceexp, and almost all topics covered by the manpage.

#kr2023 #kernel Matthew Wilcox on page-faults: "Applications typically have between 20 VMAs (cat) and 1000 (firefox). Or can be millions in pathological cases (Electric Fence) which is insane and beautiful." Is that a new stressor for stress-ng @colinianking ?

At #kr2023 @colinianking is presenting the very useful stress-ng. Stress-test not only for stability, also for bugfix, security and validation. @KernelRecipes

Vous vous souvenez de cette image du télescope Hubble? C'est venu de l'idée folle du responsable de Hubble, pointer le télescope pendant des centaines d'heures... vers rien! L'ultra Deep Field, pris en 2004, révèle ~10000 galaxies. Et bien le JWST vient de le faire. Thread👇
