Summary

The Linux kernel is evolving to prioritize security and performance over legacy compatibility. This episode covers major updates in the 7.1 and 7.2 kernels, including the removal of AppleTalk and significant filesystem optimizations.

Topics

  • Linux Kernel
  • KDE Plasma
  • Open Source Software
  • systemd
  • Filesystems
  • Cybersecurity
