Norman Feske writes "The OS Group of Technische Universität Dresden (TUD:OS) has released a live demo CD of their custom operating system project. TUD:OS is a microkernel-based operating system targeted at secure and real-time systems. Some highlights of the demo CD include a new approach for securing graphical user interfaces called Nitpicker, multiple L4Linux kernels running at the same time on top of a custom L4 microkernel, a survey on the reuse of device drivers on the TUD:OS platform, native Qt-applications, the DOpE windowing system, games, and a lot more. More information is available at the demo CD website demo.tudos.org. And yes, there are screenshots, too!"
