I share your sentiment that there are way too many copy-paste &quot;devops&quot; people in the industry these days; I always thought the idea was to hire people with both sysadmin and coding skills, yet a perplexingly high proportion of people I interact with these days have neither. I&#x27;d never choose to hire somebody who can&#x27;t describe a tcp handshake, explain what  epoll_wait() does or whiteboard a hashtable, but that&#x27;s the state of  our industry (and, probably, why those of us who can are in such high demand...)<p>Nonetheless, it seems silly to complain about a lack of knowledge and then complain about somebody trying to share knowledge. I&#x27;ve definitely wanted to lock coworkers in a room with a copy of _The_Linux_Programming_Interface_ before, but maybe a video series on similar topics would be better-received.
