A short TFiR clip in which Linus Torvalds explains his view that respect should be earned rather than given, in defense of his blunt and insulting style.

Casey Muratori's long talk arguing that modern software has ballooned to tens of millions of lines because of hardware and OS diversity. He proposes a stable ISA for entire system-on-a-chip packages and recalls when games shipped with their own boot disk.

Fredrik Knudsen's 86-minute documentary on Terry A. Davis, creator of TempleOS, tracing his work, his schizophrenia and his decline. It is a chronological video essay built on his public posts and videos.

A short animated simulation comparing how Multics and Unix were developed, showing why Unix's small composable programs and pipes gave it a efficiency advantage. It frames Unix as a moonshot achievable by a small team.

Bryan Cantrill's Papers We Love talk on FreeBSD Jails and Solaris Zones, tracing how OS-level virtualization grew out of chroot and the limits of the traditional UNIX security model.

Liz Rice live-codes a minimal container runtime in a few lines of Go at GOTO Amsterdam 2018. She explains namespaces, control groups and what a host knows about its containers.
