I’m not a sysadmin, but want to at least read the contents page - after 20 years full-stack dev I’m painfully aware there’s a lot of things I don’t understand lower down the stack.

What is a "full stack" developer? This is something that always bothered me...

I always assume someone who can build a small production web app from DB Schemas to the front end, including authentication and payments but nothing more specialist than that. Able to jump in anywhere along that stack and be dangerous enough. Probably abstracted via frameworks, so knowing one in-depth front-end and back-end.

IMO it should be somebody who can build a Linux kernel module or a single page web app. They can do explicit memory management in C, or query a DB via ORM. But the way it's used is usually just "can write both server and client JavaScript."

I'm thinking pancakes.

A developer that writes Javascript and sometimes runs it in Node as a server process or as a desktop app in Electron, but actually doesn’t know the /full/ stack at all.

It's unimportant to a certain kind of IT person that's always been out there. But it's useful to people that are curious on how things work...I really don't think those people went away.

I have over 8 years experience and don't find this is the case. Maybe it is only for junior roles nowadays? Sure I've been leetcode'd in interviews (and sometimes failed!) but normally it's more conversation driven with a little project and/or code review.
