Matthew Garrett - Powering Down
Power management - from laptops to rooms full of servers - is a topic of interest to everyone. In the beginning there was the desktop computer. It ran at a fixed speed and consumed less power than the monitor it was plugged into. Where computers were portable, their sheer size and weight meant that you were more likely to be limited by physical strength than battery life. It was not a great time for power management.

As an aging programmer with a life-long relationship with multithreaded code in various environments I love the idea. Imagine a threadpool with a choice of fast, cpu-bound threads and less critical (or memory-bound or io-bound threads), where the main thread can choose to which class of thread it will dispatch a task.
