You'd often get the error when there was paper in the printer though. Turns out the cause is the slightly different size between US letter page size and A4 page size. Technically the printer's correct to complain (for the same reason it'd be correct to complain about an A4 sized print while full of A5), but virtually nobody gives a shit about that difference and so the "PC Load Letter" message just translated to "You have to push that stupid button before I'll do anything because pedantry."
Additionally, don't copy and paste anything until you understand it. If you don't understand what code golf is being spewed, don't take the top answer. If you don't understand any answer, you probably don't understand the underlying systems well enough and need to re-evaluate what your asking for.
The only difference between a novice and a professional is that a professional checks what they are copying to understand it first before allowing it into their codebase.
Novices copy code to avoid having to understand it. Professionals copy code to avoid reinventing the wheel.
ChatGPT is making me better because I've learned not to fucking trust it and double check everything it spits out to ensure its actually doing what's asked of it.
I use it to help me lay out pseudo code and check it against what I come up with. It has made the way I structure things (and comment on things) way better.
Didn't want to put too many details in the question for privacy sake. Knew a guy with your name in college, was curious if you were the same. Have a great day!
