GoKawiilQubes OS creator details 2011 scheme for splitting digital life into security domains
The post describes a personal setup built on Qubes OS that separates work, personal, and untrusted activity into isolated lightweight AppVMs, each color-coded (green, yellow, red, and extensions like blue and black) to signal trust level. Each domain is restricted to specific network access, such as a 'work' domain limited to an encrypted work email server, with untrusted files opened only in Disposable VMs.
