SumUp is a simple tool that shows all possible combinations of numbers that add up to a given sum. It's useful for certain types of puzzles, like for example this killer sudoku.

Use this library to run any process in the background without blocking the console. It will start a child process, detach it, and save its PID to a file in order to be able to stop it later.
