AppleScript to set macOS audio input device to "Internal Microphone"
-- Sets your audio input source to "Internal Microphone"
-- Frequently needed if you use bluetooth headpohones and
-- run the Xcode iOS simulator, which will often set your

Swift code to find and count all Circular Primes below 1 million (Project Euler problem 35)
// Circular primes
// Problem 35
// The number, 197, is called a circular prime because all rotations of the digits: 197, 971, and 719, are themselves prime.
//
// There are thirteen such primes below 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97.
//
// How many circular primes are there below one million?
