Law of Averages – Load Averaging

Load averaging can be a source of confusion for admins. We provide a look at some basic considerations.

Assigning Privileges with sudo and PolicyKit

Building Virtual Images with BoxGrinder and VMBuilder

Creating a virtual machine manually is straightforward but too time consuming if you regularly need to set up many virtual machines. The BoxGrinder and VMBuilder programs let you automate this process.
