This man is a board certified turbo nerd. I very much like for example his succinct explanation of NixOS, with concrete examples of what it makes easy that can be remarkably difficult on other distros sometimes, and how he likes to time his arrival in meetings so that he comes in exactly on the second that the meeting starts (I actually used to do the same with meetings that I was running, setting the clocks if I needed to so that their second hands were accurate.)
Also: "People will use screen sometimes, if they're very old." ๐
