Turns Out Floats Are Just Structs

The code reveals floating point numbers for what they truly are: just fancy structs with a sign, exponent, and mantissa wearing a trench coat. The programmer manually constructs a float by setting each field, then casts it back to a float with that sketchy pointer manipulation. And of course, there's the mandatory comment warning you to never actually do this in production because bitfield layout will betray you faster than a coworker who "fixed" your code. Typical C behavior - giving you enough rope to not only hang yourself but the entire dev team.

Always Doom

The ultimate flex in computing isn't fancy algorithms or clean code—it's getting Doom to run on literally anything with a circuit board. The iconic FPS game has been ported to calculators, printers, ATMs, and probably your smart fridge by now. It's basically the "Hello World" of hardware hacking, except with demons and shotguns. Those little cacodemon sprites at the bottom perfectly represent the gleeful chaos developers feel when they manage to cram a 1993 game into yet another device that has absolutely no business running it. Because in the world of tech, the question isn't "can we?" but "why haven't we yet?"
