On fingers: you need to dig up potatoes. The usual dig program from start to finish. Multithreaded. You gather friends and give them shovels and garden beds. They dig, the speed increases linearly. The collective farm is the same, but there are more people, there are not enough shovels for everyone. You single out an individual who distributes shovels, bags, shows where to go to cars, pushes lazy people. Fig with him with the field, they gave you a collective farm, your thredpool has grown, you need a planner and locks so that people do not dig potatoes while there are no cars, but for example, they went to the farm to load manure. Here's something on the fingers about multithreading
