Info Radiation vs Info Refrigeration - a metaphor

Is a metaphor a form of lightweight model?


"All models are wrong, some models are useful."
-- George Box






The metaphor of information radiation is quite well know to many in the software industry.  Did you ask why?  Maybe because much of our work is very hidden from view, until we run the program and the computer interprets the code to produce some desired outcome.  Even that outcome may be obscured from view, and we must produce reports upon the data that the program produced.  So in a world where smoke and mirrors are common, one antidote to the common problem of not knowing where one is along the path toward product completion, a visualization is a powerful tool.

Generally speaking the information radiator has similar properties to the old fashion building heat radiator that used a steam media source to heat heavy iron and radiate the heat from the iron into the room.  It feels great to be standing next to a radiator when you've just come in from the cold.

What is the refrigeration process - what's required to cool some air?  Currently we use the 200 year old Carnot cycle to produce the cooling effect that your summers are known for.  I doubt that my home of Dallas Texas would be the Mecca of IT if not for Mr. Nicolas Carnot and his research into what would become air-conditions environments.  A comfortable 70 degrees indoors while the Texas sun is 95 in the shade.

I will leave the internal working of the AC unit to your study (I did it back in college - fascinating stuff).

When we put information is some systems we encode or compress it in such a way that the storage is efficient.  Think of a data base, significant work is done upon the data to store it.

When we pull it out of those systems we also must now do work to make the data into information, and then do more work to make the information understandable by the people that have little knowledge of where the data came from, the purpose of storing the data and the context from which that data/info may have resulted.  Someone will interpret that context, information and purpose and try to convey all this in a summary of the meaning behind larger data sets that the important people reviewing the information have time for.  This expansion of the information and subsequent summarization or generalization takes energy from the system as a whole.

pondering the connections - AC to info refrigeration metaphor....  what do you see in this metaphor?

is there a useful model to play with?

Software Development terms applied to Home Construction

Let's Invert the typically wrong headed view of Software Development project management as a construction project.  We can map it the other way just to see if it works... to have some fun, to explore the meaning of phrases we toss around quite frequently.


Normally Project Management terms come from a construction domain.  We are going to apply the lexicon of modern software to the construction of a home.  We will follow the construction project and meet some of the people doing the work.

This is a very small (8 homes from $600,000 skyward) program in my 30-40 year old neighborhood.

About 6 months ago I saw the programs landing page go up.  It gives casual observers and some of the stakeholders a general idea of the intent of the program.  And most importantly who to contact for additional information if you happen to be interested in their products.

The Refuge program has 8 product projects and has them running independently.  Yet much of their DevOps infrastructure has already b…

Where is Shakespeare When We Need Him?

We are desperately searching for a term for people that connotes the best of human kind.  The creative, sensing, combinatorial synergistic, empathic solutioning persons that have yet to been labeled with a role name that works.

Some of the old terms:
Staff, Workforce, Human Resource, My Team, Army, Company

Shakespeare created 1700 words in his time.  He mutated verbs to nouns, and vice-a-versa, transformed verbs into adjectives, and formed words from whole cloth never before heard.  This skill is rare, but there is a poet that can create the term we need in the twenty-first century.

What should this term define?

21st Century Human Resource; the generalizing specialist.

Yes, but what more?  What less?

Suggest your poetry in the comments, let us see if we cannot do 1/1700 as well as The Bard.

By-the-way; who create the phrase "coin a word"?

One Dark and Stormy during a Hurricane

I'm from the Carolina's where legend has it that our family commonly just hunkered down in the home on the coast and waterways than to head for inland shelter. Now that's from the old school days of barely improved (read paved) roads. They counted a storms severity by how high on the back porch steps (about 15 - top to ground) the water reached.  I don't recommend this action in todays world of long range forecast and transportation options.

I do recommend a drink or two in a hotel bar, far far away.

This is the week that Harvey came ashore in Texas.  I live on a hill in the little old town of Grapevine outside Dallas and Fort Worth.  And thank you all for letting me know that a storm is coming... I didn't get out and walk Malibu before the rain hit, so I grabbed a hat and we went anyway.  Much nicer walk with the drizzle, I'd say.

I'll raise a glass to you - if you were not smart enough to do the responsible thing, at the last responsible moment.

David's notes on "Drive"

- "The Surprising Truth about what Motivates Us" by Dan Pink.

Amazon book order
What I notice first and really like is the subtle implication in the shadow of the "i" in Drive is a person taking one step in a running motion.  This brings to mind the old saying - "there is no I in TEAM".  There is however a ME in TEAM, and there is an I in DRIVE.  And when one talks about motivating a team or an individual - it all starts with - what's in it for me.

Introduction

Pink starts with an early experiment with monkeys on problem solving.  Seems the monkeys were much better problem solver's than the scientist thought they should be.  This 1949 experiment is explained as the early understanding of motivation.  At the time there were two main drivers of motivation:  biological & external influences.  Harry F. Harlow defines the third drive in a novel theory:  "The performance of the task provided intrinsic reward" (p 3).  This is Dan Pink's M…
