...And The Two Hard Problems

The famous Phil Karlton quote gets the Harry Potter treatment it deserves. "There are only two hard problems in computer science: cache invalidation and naming things" – but throw in "off by one errors" and you've got the holy trinity of developer suffering.

Voldemort showing up as "I AM LORD VOLDEMORT" is chef's kiss because naming things is literally his entire villain origin story. The Deathly Hallows symbols representing the three problems? Brilliant. Because just like those magical artifacts, these problems will haunt you until the end of your career.

Cache invalidation will make you question reality itself. Naming things will have you staring at a variable for 20 minutes. And off-by-one errors? They're why your loop always misses that last element or mysteriously crashes with an index out of bounds. The Elder Wand couldn't fix these even if it tried.
