Granola is an application that is used to save energy on your desktop or server. Granola saves energy by applying dynamic voltage and frequency scaling (DVFS) to the CPU, so when you browse the net or you use a word processor the CPU frequency is scaled down and you save a bit of energy.
So a requisite for granola it’s hardware support for Dynamic Voltage and Frequency Scaling (DVFS). DVFS is available on most modern Intel and AMD processors, but may require being enabled in your computer’s BIOS (read this page for information on known models). If DVFS is not available, or turned off, Granola will let you know when it attempts to start up for the first time.

After about a month of work and various tests I’m proud to make public the result of this commitment:
UbuBox “SalentOS” live 11.04.
The idea to make a personal operating system, flashed in my head for quite some time, but for one reason or another I never managed to get to work seriously on such a project. In these days I decided to commit myself “full time” to it and I did it, also pushed by the wave of news that are coming in the world of the penguin! I did not, initially, planned to make UbuBox “SalentOS” public. Then, along the way, thanks to the advice of some friends and the realization that the system satisfy me, I said “Who knows … maybe this could satisfy someone else too. Why not make it public?”.
