The humble if statement: so simple, so short, so trivial. But do you know how it works? I mean, how it -really- works? Join us on a trip down the rabbit hole to find out! Our journey will take us from PHP to C, from Assembly to Machine code, from CPU to Transistor and beyond. We’ll discover all sorts of interesting things you many never have known about programming, physics and even the universe itself… I can’t promise that you’ll return from the depths of the CPU, but if you do, you will not be the same.
