An Update

I thought I had made this post years ago; anyway, here it is.
Suffice it to say that if you are waiting for stuff to appear here, forget it. Instead, look at the new places I have moved to: My Wordpress blog, my website, and my various Tumblr accounts. Also +Arlo Barnes. Thanks!

How many digits?

Of course, it is evident that the /index2/ page has pi to 1 meeeellion digits. But how many digits does the site URL go to? The preview on the front page? By the way, when mathematicians or number enthusiasts (amateur here, I like i^i) say 'digits' in the context of irrational numbers, particularly transcendental numbers, particularly pi, they mean to the right of the decimal point. So, consulting [], we get 63 characters for the URL and 399 characters for the preview. For those who are interested, the where the URL-length string ends in the preview is (as I render it, latest stable build of Chrome) at the 2 just beneath the space between the l and the p in 'places'.
On a different note, I want the sticker mentioned ( because it is 3.14" square and $5.

@FormSpring: Have you ever considered how powerful a consentual statistics tool you have here? Also [double-asking is cheating, I know], what is the story behind the corporate-sounding name?

The Climate Vulnerability and Capacity Analysis Handbook adapts its definition from UNISDR (2009) defining resilience as “the ability of a system to resist, absorb, and recover from the effects of hazards in a timely and efficient manner, preserving or restoring its essential basic structures, functions, and identity.”
The IPCC defines resilience as “the ability of a social or ecological system to absorb disturbances while retaining the same basic structure and ways of functioning, the capacity for self-organisation, and the capacity to adapt to stress and change.”
While Walker et al (2004) define resilience as “the capacity of a system to absorb disturbance and reorganize while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks.”
In these cases resilience emphasizes a system’s ability to maintain or return to specific structural or functional features–i.e. to maintain its identity, its durability, its persistence.  But as noted by Erica Jen in her article “Stable or Robust? What’s the Difference?” (2005), the choices of features or structural elements that we attend to are important for assessing both the capacity and quality of that responsiveness to change.
So what is the function, what is functional, and for whom?  Definitions matter.
One way to think about resilience is to imagine a couple of different water balloons.  One balloon is filled halfway full.  Another is filled so that the latex rubber that composes its surface and membrane is stretched tightly to hold the water in.  Now you can throw both balloons back and forth between each other, and neither may pop.  But what do you think will happen when the balloons are stretched, twisted, or allowed to drop on the ground where a twig might be a hazard to the already tense surface of the overfilled balloon?  It will probably pop and spill the water out.
A system’s resilience is a lot like a water balloon, and the degree of resilience is determined by how much water is forced into the balloon, the size of the balloon, and how much it is pushed to its limits.  We might think of the balloons shape, its ‘throwability’ or the thickness of its membrane as examples of functional or structural elements.  In most cases, we are looking at how well the balloon is able to maintain it shape and its continuity despite being stressed – i.e. it is functionally a ‘water balloon’, it has a round shape, and responds to the exterior and interior pressures of air and water.
Rarely do we think that a water balloon might reconfigure itself, rearranging the organization of its functions, structural elements, or features to be able to accomplish the same task differently.  What would happen if the water and the balloon separated or if the water balloon system was able to draw on other systems (e.g. refrigeration) to change the relationships between its functional elements?  What if we no longer simply considered only the water inside of the balloon as the system responding to the task of throwing? What if the throwing and catching movements were also included?  Would we still think of a resilient system, or would we start to walk a path of robustness–of being able to adjust the definitions and constraints of the systems themselves in pursuit of coevolutionary relationships between them?
Robustness is a different beast altogether – literally.  While resilience is focused on maintaining a system, we can describe robustness as the ability of a system to change and in doing so to respond to environment and to develop entirely new functions as a result.
Some argue that robustness describes the ability of a system to withstand mutations and maintain its phenotype or “shape” as a result (Wagner, 2005).  Instead I think there is a greater correspondence of robustness with transformation as used by Walker et al (2004).  Transformability is “the capacity to create a fundamentally new system when ecological, economic, or social (including political) conditions make the existing system untenable.”   I’m less sure about the “untenable” part of Walker et al’s definition.
Robustness is the ability of a system to evolve system functions, not simply maintain those that already exist.  In this way, an analogy can be drawn between adaptation/robustness and plasticity/resilience.  Similarly, I think robustness has a quality of being parametric.  Parametric architecture has the quality of being built from common construction principles, but by varying the parameter values of those rules of construction, endless forms become possible.

The Coldest I ever felt was in GRANTS New Mexico. It was Late Jan. or Feb. and there was a wind coming from the north, and it was an evil hideous cold cold cold cold wind that had nothing to stop it. it continuously blasted you and there was no where to hide. The locals called it something ( the wind had a name!) but I cant remember what they called it because it happened way back in the 70's. ( do I need to say anything about the 70'?)
