When I was in KISAS, we have trouble renaming files and folders. We literally randomly hitting the keyboard to name a picture or a video like “ashduiashduasd.mp4′. If there are changes made in the video, I would look like “KISAS – MJK final final really really final”. Even worst, “ashduiashduasd-final-really-final-.mp4”.
I don’t know why some students still using relatively unreadable code. Why do you need to name a property as “x”, “y” and “z”. Can you read it in the future? No, you can’t. It sucks.
Being explicit is very important, both maintainability as well as keeping yourself realize that you’re a human.
