Version-controlled, automagical backup and file sharing system with Sparkleshare and Fedora

On and off over the past year I’ve been working with Jason Baron on a design for a UI for system administrators to control processes’ and users’ usage of system resources on their systems via the relatively recently-developed (~2007) cgroups feature of the Linux kernel. After the excitement and the fun that is the Red …
