How Grace Hopper Named the First Compiler
In 1952, Grace Hopper and her team at Remington Rand built the first compiler, a program that translated human-readable code into machine language. Hopper's A-0 system was met with skepticism, but her insistence that programmers should write in words rather than cryptic binary paved the way for every modern programming language. This episode explores how the compiler was born, why the military initially dismissed it, and how Hopper's legacy of 'we've always done it this way' still shapes tech…
How the First Bar Code Scanner Changed Retail

How the First Hard Drive Weighed a Ton
In 1956, IBM shipped the 305 RAMAC, the first computer with a random-access hard drive. It weighed over a ton, stored just five megabytes, and cost roughly $10,000 per megabyte. Yet it changed computing forever by making data instantly accessible instead of sequential. In this episode, Lucas and Luna explore how the RAMAC's spinning platters and moving heads set the template for every drive since, why the 'disk drive' came to dominate storage, and how the technology shrank from a room-sized…
How the First Computer Bug Was Found in a Moth
