    1. Linux Memory Management at Scale

      "we had to build a complete and compliant operating system in order to perform resource control reliably"

      epic real-talk. the only people on the planet who seemed to have tamed linux for workloads. controlling memory. taming io. being on the bleeding edge, it turns out, is almost entirely about forward-progress. what can we reclaim?

      • oomd for memory protection
      • fbtax2
      • psi monitoring for io regulation
      • cgroups v2
