My first exposure to anything that could be related to professional day-to-day work was when my dad taught toddler-me how to use DOS in Windows 3.1 Unfortunately for me, I didn't do anything else remotely related to programming until my 20s. But I think this early exposure to a command line made it much easier to go through tutorials, since everything that I used to learn early on involved a unix terminal. Anyways, command lines/terminals make me feel good. I don't think it's nostalgia. I'm not exactly sure what to call it. It's the same feeling I get when I occasionally have to write Objective-C code. It's not the first language I learned, it's not my main daily language, and I'm not particularly good at it. But it's the first programming language that I was paid an actual salary to use. It helped me start my career, and it makes me happy. It just feels warm and comforting.
