Carl Sagan famously said, "If you wish to make an apple pie from scratch, you must first invent the universe". Like an apple pie, many things that seem simple at first are extremely complex; it's just that we choose to ignore the complexity for practical purposes. In this post, I'll try to go as low as I can in abstractions of Frappe Scheduler, but I don't promise a recipe for inventing the universe.Carl Sagan famously said, "If you wish to make an apple pie from scratch, you must first invent the universe".
