Software failures in wireless sensor systems are notoriously difficult to debug. Resource constraints in wireless deployments substantially restrict visibility into the root causes of node-level system and application faults. At the same time, the high cost of deployment ofwireless sensor systems often far exceeds the cumulative cost of allother sensor(More)

Some projects are simply too big to finish on the release schedule that you want to maintain. Rally's agile engineering team delivered a very disruptive architectural change lasting nine months in parallel with three releases. This paper will show how this was done without prolonging the usual release cycles and without technically crippling our product or(More)
We present an early vision of a system that allows computer controlled rendering of physical surfaces, terrains, and environments by manipulating grids of " physical pix-els " or rods whose heights can be raised and lowered on command. A user would be free to walk within such a dynamically deformable physically rendered environment (PRE). The system would(More)
We present an early vision of a cyber-physical environment in which computer controlled rendering of physical surfaces, terrains, and environments is achieved by manipulating grids of "moving physical pixels'' or "moxels", whose heights can be raised and lowered on command. A user would be free to walk within such a dynamically deformable physically(More)
