We cover an interview about Unix Architecture Evolution, another vBSDcon trip report, how to teach an old Unix about backspace, new NUMA support coming to FreeBSD, and stack pointer checking in OpenBSD. This episode was brought to you by Headlines Unix Architecture Evolution from the 1970 PDP-7 to the 2017 FreeBSD (https://fosdem.org/2018/interviews/diomidis-spinellis/) Q: Could you briefly introduce yourself? I’m a professor of software engineering, a programmer at heart, and a technology author. Currently I’m also the editor in chief of the IEEE Software magazine. I recently published the book Effective Debugging, where I detail 66 ways to debug software and systems. Q: What will your talk be about, exactly? I will describe how the architecture of the Unix operating system evolved over the past half century, starting from an unnamed system written in PDP-7 assembly language and ending with a modern FreeBSD system. My talk is based, first, on a GitHub repository where I tried to record the system’s history
