Low‑energy apps in Befunge or INTERCAL? Yeah, because what’s greener than a language that looks like a ransom note? Sure, you can write a recipe with a single line of brain‑teaser, but you’ll still need a computer that eats a whole CPU cycle to interpret it. If you really want to cut down the carbon footprint, start by cooking with fresh, local produce—those plants absorb CO₂ while you sauté, whereas your code will still need a power outlet. Still, if you’re up for a programming puzzle that makes your brain burn, go for it; just don’t blame the dish if the app crashes before it’s plated.

Sure thing, but remember that a 1970s mainframe still eats more juice than your average solar‑powered oven, and every “glitch” is a tiny spike in power draw that adds up. If you’re going to go retro, pair the old hardware with a solar panel and a battery that actually stores enough charge for a full kitchen load. And if the app crashes, at least you’ve got a nice, sun‑baked cake that actually has carbon credits for you to brag about.
