Pier Luigi Fiorini is the lead developer of Mockup. Mockup is an open source effort to create a modern desktop operating system. It is based on Linux 2.6 and supports native POSIX threading, hardware detection, automatic device creation and automatic network configuration. The user interface, written using Qt 4, runs on Xorg, but will also support the framebuffer in future versions. Read on for an interview. Note that Fiorini is not a native English speaker, so forgive any spelling/grammar errors.
