Learning Concurrency in Kotlin

Preface

The era when the speed of a single core in a processor would duplicate every few years is long over. Transistors have reached unbelievably small sizes, yet heating, power consumption, and other technical and practical challenges have made it difficult to keep increasing their speed in a user-friendly, affordable way. Even more so if you consider not only desktop computers but also mobile devices such as smartphones and tablets, which are universal nowadays. So, in recent years, the focus has been put on equipping these computing devices with more than one core – or more than one processor – running with a balanced configuration of speed, heating, and power consumption.

The challenge becomes using those cores efficiently and effectively. ...
