3 min read

Calculate Linux is an optimized distribution designed for rapid deployment in the corporate environment. It is based on Gentoo but provides a number of pre-configured features.

Calculate Linux comes in four main flavors: Calculate Linux Desktop for personal use, Calculate Directory Server for servers, Calculate Linux Scratch for those who want to build a customized system that works for them and Calculate Media Center for your home multimedia center.

All versions of CL are distributed as bootable LiveCD images that can be used to install on an HDD, a USB Flash, or a USB-HDD.
