The Internet of Things (IoT) connects a variety of small devices, via gateways, to the cloud. Use-cases often require IoT devices to run logic that is not pre-determined before deployment, and that must be updated during the life-time of the device. In this paper, we explore the potential of over-the-air scripting and updatable runtime containers hosting application logic on heterogeneous low-end IoT devices. Based on RIOT and Javascript, we provide a proof-of-concept implementation of this approach for a building automation IoT scenario. A preliminary evaluation shows our prototype runs on common off-the-shelf low-end IoT hardware with as little as 32kB of memory.

The Pact environment is a software engineering environment (SEE) being built in the Pact project. The environment is being constructed on the PCTE interfaces. The project has detined an environment architecture which identifies Common Services. These are reusable tool components that factor out code that would otherwise have to be developed in several tools, and which significantly increase the integration of the environment. The main activity of the Pact project is to develop "method-independent" tools, independent of a particular engineering technique for the production of software.
