The Flux Research Group works in software systems. Our
interests and work cover many areas, including both local and
distributed operating systems, networking, component-based systems,
programming and non-traditional languages, compilers,
information and resource security,
and even a pinch of software engineering and formal methods.
All of our publications and
some presentations are available. Additionally,
we try to produce and distribute usable versions
of the developed software.
Five of our current projects:
