Theres a hundred edge cases to consider and many of them very non-obvious to our feeble linear time oriented mortal minds.










Learning to code isn’t it. Spending so many hours practicing Dijkstra’s algorithm and object oriented programming is relevant to building software for other people to use, not controlling it or maintaining your own things.
If you want control of your own machines, learn the terminal, learn operating systems and how to understand network APIs. Learn how to use WireShark to examine how your own devices talk to the internet so that you understand how they work. A generic programming course will not take you in this direction.
