News: Structure, Stability and Simulation

  1. Structure, Stability and Simulation (1 messages)

    "Our bodies are prisons for our souls. Our skin and blood, the iron bars of confinement. But fear not. All flesh decays. Death turns all to ash. And thus, death frees every soul." - The Fountain (2006)

    In engineering, and possibly life, there is always this tension between adaptability and structural stability. We want our designs to be highly adaptable, which many confuse with agility. With adaptation, our designs attempt to intelligently respond to change, sensed within the environment, with more change, though generally far more confined and possibly transient, at least initially. But there are limits to how far we can accelerate adaptation, without putting incredible stress on both the environment and the very system contained within. This applies to both structural and behavioral adaptation as it is hard to decouple the two due to system memory.

    Structure is important but not because we need rigidity but because structure is the basis for a systems memory. I see structure in code and software architecture as a formation of system memory. Sometimes the memory is formed, tainted, in the early development of software in defining modules, classes and methods. Bones. Other times we create these memory structures in the composing of code and data flows. Blood. If change was indeed accelerated (beyond limits) there would be insufficient time for memory to form around such structures, leading ultimately to a breakdown in the system as prediction in response to change becomes chaotic. And it is not just prediction that is impacted but our ability to respond because the structure is the means for response in many systems. Just imagine the cells in your own body were constantly re-organizing in response to stimulus. You would not be able to effect change in the physical world because you might not actually have an arm to do so and I have not even discussed the effectiveness of this in an environment with many other participates undergoing their own set of changes. The structure of our body is a kind of memory of evolution but it is also how our own memories form after birth. Read on.....
