I had a course in uni that taught us assembler on z/os. My advisor told me most students fail the course on the first try because it was so tough and my Prof for that course said if any of us managed to get at least a B in the course, he’d write us a rec letter for graduate school. That course was the most difficult and most fun I’ve ever had. I learned how to properly use registers to store my values for calculations, I learned how to use subroutines. Earned myself that B and went on to take the follow up course which was COBOL. You’re not crazy, I yearn to go back to doing low level programming, I’m mostly doing ruby for my job but I think my heart never left assembler hahaha

I didn’t know about registers, thank you for this!

If it makes you feel even better, I’m a software engineer and I had lots of trouble learning to use GitHub and git, it’s embarrassing to admit it but I’m super glad I learned!

BMW I have has the same thing going on. I was working on the car and thought to unplug the battery before continuing to work, unplugged it, closed the trunk, with my tools inside, closed the other doors and went inside for a snack. That was a rough day. I figured out that jumping the car would let me pop the trunk real quick and that saved me. Horrifying few hours before finding that out though
