Currently on holidays. Must admit it feels good to have thinking capacity for random things I find interesting which are not mathematics

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).
