 Quantum Computing (circa 2024) - No one has explained it to me but as an OLD programmer who ages ago studied how programming and digital computation work I have created the following broad model for understanding. 

Initially computers did one instruction at a time in sequence - very linear programming.  Computers got faster and more complex.  They then started things like "caching" - preloading instructions into very fast memory. Then another iteration did pre-instruction functions (prefetch, instruction decoding,..).  Moore's "Law" drove chip capabilities further and further allowing even more potential.  Attention turned from electronics to complex software/electronic advances creating chips and software that could execute more than one instruction at a time. This lead to hyperthreading and multi core chips.

My expectation is that quantum computing/computers involves new super fast, super dense computing technologies requiring new advanced programming techniques. For example doing parallel executions on a massive scale but requiring massive parallel validation of outcomes. If I am correct on the infamous Turing Test provided proof of such possibilities. 

The downside is the scaling factors are also gargantuan (both hardware and software) so I don't expect mass practicality in any near future. 

Scale matters! I point to our human brain.  It's "computational" ability is large but even our brain takes short cuts to run real-time results. This suggests nature understands scaling issues and makes practical choices!

Publisher's Summary

Rain of Gold is a true-life saga of love, family and destiny that pulses with bold vitality, sweeping from the war-ravaged Mexican mountains of Pancho Villa's revolution to the days of Prohibition in California.

It all began when Villaseñor’s maternal grandmother sat him down in their little home in the barrio of Carlsbad, California, gave him sweet bread and told him the story of their past. Of his mother Lupe, the most beautiful girl in the whole village who was only a child when Villa's men came shooting into their canyon. And of his father Juan and his family, reduced to rags and starvation as they sought refuge across the border, where they believed that endless opportunity awaited.

Lupe and Juan met and fell in love in California, but they found that the doors to the Promised Land were often closed to those from south of the border. His father was forced to take the law into his own hands, in spite of his wife's objections. With love and humor, Villaseñor shares this passionate love story that celebrates the triumph of the human spirit.

An all-American story of struggle and success, Rain of Gold focuses on three generations of Villaseñor’s kin, their spiritual and cultural roots back in Mexico, their immigration to California and overcoming poverty, prejudice and economic exploitation. It is the warm-hearted and spirited account of the wily, wary and persevering forebears of Victor Villaseñor.

Reader’s Review (2024/12)
(Audio book version)

Certainly for me a novel and production. 
My original intention was to explore some of the folklore, customs and attitudes of the Hispanic and native Indian cultures from the mountainous areas south of California and New Mexico borders. To a restricted degree this novel does weave some of this into the characters and times presented.

While the Publisher’s Summary outlines key plots, many themes run this long and rich saga. From impacts of war, harsh conditions, displacement and integration in early 19th century America. For me rich development of family members creates the foundations that present colourful history and deeply rich family lives.

Two powerful characters not mentioned in the Publisher’s Summary are the family matriarchs. Juan’s mother and Lupe’s mother form contrasting positions of roles in the large nuclear families from two very powerful women. Many of the dialogues between mother and child I found some of the strongest moments in Rain of Gold sometimes bringing me to tears and wonderment.

The narrator Johnny Rey Diaz developed dialects and accents enriching characters enhancing my mental imagery. Given the length of the novel, I applaud the narrator in his consistency throughout.

While only achieving highly focused folklore, customs and attitudes, Victor Villaseñor’s writing grasped my interest and heart through a most fascinating journey of the generation that produced and raised him.

Muy agradecido.

The Invisible Gorilla

This is such a wonderful example of what we are: inside our skull our brain aggregates inputs from our entire body of sensors. The amount of continuous information is truly massive and beyond digital processing in real-time.  So evolution selected for brains that create simplified models with fast comparison for survival including bodily function. (Importantly this modeling is not necessarily isolated in our skull.)

Concentrating, focusing our visual modeling on counting ball passing, results in loss of focus on other modeling that goes on. Besides 'missing' the gorilla most other modeling receives lower priority. 

Consider what might those observing would report if other sensors were triggered at the same time: loud bang, a flash in peripheral vision, smell of smoke, ...?

Modeling is always happening as sensory data is continuous and there are processes for  priority, decision weighing,  involved in models a.k.a. modeling for survival.

We model everything! I  believe our modeling function has no need to differentiate abstract models (models of models ie ideas) from objective sensory models (ex sight, sound, touch,...) 

As an animal species, it appears our modeling abilities evolved in a non linear increment. My suspicious ( idea modeling 😁) is that evolutionary selection drove a fractal step level increase in abstract modeling ability.

Okay time to model my ass out of bed, make coffee and do chores. Thanks for your indulgence of my ramblings.

We model EVERYTHING!

 

My position is a broad philosophical one. We model EVERYTHING!  I'm rather trapped in my purist view.  By my definition, all that is possible are mental models thus we can not truly observe any objective reality. Now I’m not trying to dis the scientific process – it’s the only logical/rational means that is coherent.  What I mean is humans can not trust the mental models we construct of the experimental process we can only model an interpretation. Mathematics is a wonderfully logical abstraction however it to is subject to our internal modeling process for interpretation. That said it provides huge guidance for us.

I can not think (model) of how I can exit this logical trap. Nor can I think of why evolution might have developed a means for us to escape the modeling trap if the underlying driver if evolution is just advancing survival if a universe of entropic soup is true? Very frustrating for me.

So, the scientific process allows us to logically investigate the objective reality about us but we remain trapped in the model everything paradigm. I am faced with questioning everything while believing my mental thoughts are always (infinite?) models of all questions as that is what I am?

Regarding N and S, both still are modeling. As far as I expect there is no single modeling function. This might rock your socks a bit but not only do humans model, I think the entire universe models!  I don’t believe humans are highly unique in any fundamental way.  It’s not surprising to me that there are groups with common models and that we identify them and create models of these groups.  It’s what we do.

Language is another fascinating modeling.  Not to devel into that here but it does not surprise me that AI (large language models) are getting faster and better able to create consistent and coherent results.  Compared with human modeling (thinking) I expect AI will struggle to be as innovative given its narrow access to data though it is expanding with sound and visual data.  For me that reflects well with my view of modeling for survival ie human modeling is highly specialized. 

Need more coffee – take care!

Laundry Matriarch


Laundry Matriarch

A bed made with sheets
And sheets for my bed
One I yearn for
The other I dread
Sheets with many folds
From love making so bold
While others so trim
Made so by sore limb
Oh for a day on my back
Instead of on track
Just sheets stripped a-bare
And your passionate stare

A Crucible Of Stars


A Crucible Of Stars

By Ken Metcalfe
The night is bright
With my heart's delight
Behold the tales unseen.
\My mind is fraught
Of these tales unsought
Tales grand and serene.
\No hell could be worse
Then to suffer this curse
So mortal and so keen.
\But continue to stare
At God's wondrous fare
Oh what might have been!
