  1. Docker Engine v29.4.3 mitigates the critical Copy Fail (CVE-2026-31431) vulnerability. Update immediately if you cannot patch your Linux kernel yet.

  2. #TIL #cgroups' memory.current metric includes any #pagecache entries that a process in the #cgroup caused to be inserted, even if other processes are accessing it too.

    This means that anything related to #systemd unit's memory accounting also inherits this property.

    If your #emacs systemd unit reports insane memory usage (usually ~10G for me), this is why.
    It's actually not emacs' fault for once ;)
