very cool. > When writing software for early PCs, every single byte and every single instruction mattered, so developers often wrote code entirely in assembly language simply to be able to physically fit their software into the available memory, and to be able to access the computer’s resources and internal workings. This made me a bit sad. Imagine how fast things could be today if developers still had this mindset. Of course I wouldn't advocate writing everything in ASM, but the adage that computers are fast, write inefficient code...is disappointing to say the least.
