Nothing fancy, I'm just playing about... Yeah I can appreciate just how difficult this is to grasp. Fortunately I don't have to learn this for a job as I've already got a quite decent software engineering job, but I wouldn't mind messing around with this sort of thing; as difficult as it is, it is quite fun!What is your ultimate goal with what you're doing? This stuff is BS hard, takes years to get good at and is likely not to get you anywhere in life.
