A few tools I built, running on one laptop at home.
Picks tonight's dinner from recipes around the world, remembers what you've already made, and prints a card you can send to whoever's cooking.
Reads a flight log from a system-ID sweep, tells you whether it's clean enough to tune from, and writes out gains you can load back into the aircraft.
Tracks what's in the freezer and the pantry, how many meals that adds up to, and what to pick up on the next shop.
