Hurry! Fetch the 2×4 stretcher.

The mythical 2×4 stretcher analogy.

When I was in high school I worked with the school maintenance crew. This was in the late 1970s when schools were growing and therefore tearing down old buildings to construct new modern building on the site. Given that construction of the new building would take several years the problem of where to house classrooms durning the destruction/construction years was typically solved by building classrooms in the gym and auditorium. The first summer I worked with the crew we were constructing one of these temporary classrooms in a gym. I was the gopher for Ike, and old codger who was always up to something. One fellow was measuring and calling out dimensions and Ike and I were cutting 2×4s to length, as fast as we could go. I would hold the 2×4 on the saw horses and Ike would measure, mark, and cut, then I would run the piece over to a pair that would nail it in place. We were all working fast, a well functioning team. When Ike, exclaimed, “$#!T, I cut it too short, Koontz run get the 2×4 stretcher in the back tool box of my truck – hurry! You’ll know it when you see it.” So, off I run to find the stretcher. I pull out every tool in the truck’s toolbox, but the stretcher wasn’t there. So back in to tell Ike and he said “maybe I was using it at home and didn’t put it back, go get Jim’s, hurry! So out to Jim’s truck to rummage through his toolbox I went like a flash.

Well if you have every been played for the fool by a master craftsman such as Ike, you know that he can keep it up all day long, as long as you are hooked and on the string he is intense and serious, and has another place to look. After I finally wised up and “spit out the hook”, the whole crew fell on the floor laughing for 20 minutes. I joined in after about 15 minutes, of being mad and extremely embarrassed. That was the first of many exploits that Ike would lead us on that summer. He worked hard and played hard, all at the same time!

I don’t know of any 2×4 stretcher stories in the software industry, but everyone that has been the young apprentice on a construction site has been asked to go fetch the stretcher. So why are there no good fish tales in software? Well for one reason a 2×4 stretcher is possible in software – it is called a refactoring, for example: Extract Interface. Software is soft and malleable, the rest of the world is not. Therefore a 2×4 stretcher is funny on a construction site, but a real possibility in software.

This doesn’t mean we cannot have fun, however! Why I remember just starting out and having an upper-classmate help me with a sorting algorithm, he took my punch cards and dropped them on the floor.

Innovation in the Automobile Industry

In the 1900s the automobile industry was the most important and innovation industry in the USA.  But one could question if this was good for our society in the long run.  And one could question if they actually innovated.

In the early 1900s there were few automobiles, very little infrastructure created to support the industry.  For example the road system was still designed for horse drawn wagons and the wagon wheel (remember a steal rim and wooden compression spoke wheel).  The future US Highways, or the 1950s Interstate Highway System at the cost of $425 billion were decades and many innovations away. There was no gas service station, there were however horse stables, farriers, and blacksmiths in each town along the roads.  There was no real "road map", there was no road naming system, like was created in 1926 - the United States Numbered Highway System.

The industry employees millions of people, and was a large factor in the economy of the USA.  It created or was created b…

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…

Timeline of Social Networks -or- the Long Haul

I was listening to KERA's Think and they mentioned the concept of social networks.  It got me think...

But the book Long Haul, is its own interesting story - A Million Miles and Counting - A Trucker's Tale.

“The Long Haul: A Trucker’s Tales of Life on the Road”
Did you know 41 million people move in the US a year?  Having moved a few times in my life, sometime with the Bed-Bugger's help, this book is a great insight into that life.
Author: Finn Murphy's CB handle - "U-Turn" The radio interview noted the concept of social networks in the 21st century.  What is a highway - but a manifestation of a social network - a trail across the land.

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…

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.

I do re…
