    I'll be giving a practice talk for the Workshop on Self Healing Systems in
    590N this week. The talk will be at 1:30 tomorrow (Tuesday) in MOR 219
    (just south of the MechE building). Goodies will be provided; title and
    abstract are below.

    Thanks,

    Jonathan

    Architecture-Centric Programming for Adaptive Systems

    Jonathan Aldrich, Vibha Sazawal, Craig Chambers, and David Notkin

    Ubiquitous computing services are a fast-growing and challenging class of
    self-healing systems that must adapt to constant failures and
    environmental changes. Writing robust ubiquitous computing code is
    difficult in current programming systems. The architecture, interfaces,
    and logic of the program are often obscured by infrastructure details,
    making the development and evolution of these systems difficult and
    error-prone.

    We are exploring whether implementation language support for software
    architecture can aid in the development and evolution of ubiquitous
    computing systems. One such approach, embodied in the ArchJava language,
    allows programmers to express the software architecture of an application
    within Java source code. In this paper, we propose an extension to
    ArchJava allowing programmers to define custom connectors. Custom
    connectors are useful in many different contexts; we show how they can be
    used to implement part of the PlantCare ubiquitous computing application
    in ArchJava.
