A Design Pattern Goes to the Supermarket
summary
The talk maps classical software design patterns onto supermarket actions: it shows Command embodied by a shopping note that encapsulates requester, items and receiver to avoid back-and-forth; Observer implemented as an in-store waitlist that notifies customers when out-of-stock coffee returns; Adapter realized by a phone translator app converting Spanish ingredient text to English for safe vegan choices; and Factory Method represented by different bakeries producing different Bread types.
