CMOS
Complementary metal–oxide–semiconductor,
also known as complementary-symmetry metal–oxide–semiconductor,
is a type of metal–oxide–semiconductor field-effect transistor fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. Wikipedia

Eh.
One more quick
one, right here.
“Do you know if there is any security on the data coming back and forth?
39:42
Or is it just, whoever has a big antenna can talk to it?”
39:45
Yeah,
39:47
security, I could find no information
about the security, which either means
there isn’t any or, it’s classified. _I’m
not sure which. _Okay.

Ephemerality is the concept of things being transitory,
existing only briefly.
Typically the term ephemeral is used to describe objects found in nature,
although it can describe a wide range of things, …
Seven people were injured, and 15 more are missing as wildfires ravage Argentina. Authorities attribute the rapid spread of the fires to high temperatures and windy conditions.

Foggy flight check. @USNavy sailors prepare to launch an F/A-18 Super Hornet from the flight
deck of @TheCVN69.
Walking is a nice exercise, good for all ages! BTW… you walked all downhill… so you rode public transportation back home? Here in Barcelona there’s a pulbic bike rental service and they noticed how some pick up locations are always full and ohers empty… since the city is roughly uphill from the sea to the Collserola range, people ride bikes from streets higher (closer to the mountains) to streets lower (closer to the sea), going mostly downhill, but don’t ride so often in the opposite direction, so there’s electric service vehicles bringing bikes from lower streets to higher ones to keep a good stock on every pick up station.
And now I’m off to bed… nighties lovelies!
Also: this the opposite art of instant messaging…
“Dead tree” books might not be what they used to be, but they still allow people from all times and places talk to us and sometimes take us to places we didn’t know.
I also had a job which used similar offset printers.
The ones we used were much older.
We had to make a photo of the product to print.
We had to develop the negative of the photo of the product to print in chemicals to generate the negative film from the camera.
We had to make a print from the final negative by sending light from the negative onto a receptive medium, which is then printed onto a media which is like a plate.
flat (planographic) image carrier
That plate is then what is used to be put on the press,
which press is then what is rotated to print the multiple instances of the same positive print.
It’s like a metallic sheet, mixed with plastic, which receives lights,
from the negative, and reacts to the negative light, which light is filtered by the negative.
You can make over 100 prints from one positive.
We printed a coloring book which I still have.
That course was 2.5 months long.
The other 3 courses we had were Technical Drafting,
Electricity, and, Cooking.

That was 4 to 5 years before we had the first advanced class program.
The year before me didn’t have that one, and, went to college before me.
However, they didn’t have that extra year of physics,
which, even though I didn’t succeed, I did get and they didn’t.

I also worked on the larger presses which printed newspapers as well as advertisement for those newspaper, which advertisement are printed on papers similar to the newspaper.
The machines also folds the newspapers and sorts the pages by numbers automatically.

At 29m 58s :
… came in a period of the most intensive
work I’ve ever known the book which we
finally published in 1944. We used to
meet at the Nassau Club virtually every
morning his wife liked to sleep alone
and I was unmarried then and had my
breakfast there, and he would join me we
continued to meet there even long after
the book had come out. _It was a wonderful
way to start the day, always full of
discussions about the events of the day.
_Many scientific matters came up and it
was a wonderful never
forgotten period. _He loved the wide-open
spaces, so we often went to sea, cause, not to
swim, because he didn’t like that kind of
exercise but to walk along the beach.
_We had very serious discussions and
these walks sort of crystallized them.
_Then, we would go home and write down
things that was a normal way of working.
_The sort of walking in the open air
seems to help mental activity. _He wasn’t
a man who sat and studied hard. _He would
think all the time and when it was ready
in his mind it came rushing up.
_He worked with tremendous energy and
fantastic speed. _I’ve seen him write 30
pages in one day. _He worked almost
anywhere any hotel room, train, wherever
he was. _The remarkable thing about my
association with phenomenas perhaps that
he as a mathematician could so quickly
and easily penetrate into the problems
of economics and sociology which I
presented to him, that is very
indicative of his basic philosophy which
was that mathematics should try to enter
new areas, new fields, not only be
inspired as it had been by the Natural
Sciences. _He expected that it would
receive great stimulus from the other
areas and I’m sure that if he had lived
he would have made great contributions,
also, for example, to biology into, in
which field he was very much interested
My Maths teacher taught advanced mathematics in 1985, for which class I was the president of.
At 32m 16s :
… but out of this study of sociology and
economics on the one side and
mathematics on the other came this book
32m 27s
which is the fruit of our joint
association.
At 32m 32s : Theory Of Games And Economic Behavior
The Theory of Games was a
landmark work in pointing the way toward
the mathematization of human
motivations. The theory deals with
problems ranging from the two-person
game in which the goals of individuals
are diametrically opposed, as in poker
and war to In Person Games involving
Complex Interaction of groups and
finally, to insights into individual
choice as it is expressed in economics.
My neighbor who was banned from the Casino for bankrupting the poker table, used this mathematical method for poker, as he was a genius.
_In 1943, Von Neumann (noyman) was one of those who
disappeared into the West to work on the
Manhattan Project. _Los Alamos, at that
time, was a unique mixture of primitive
living conditions, super secrecy and
brilliant scientific minds, all of which
combined to create an atmosphere of
intense excitement and stimulation. Von (pronounced ‘fun’)
Neumann took part in
most of the crucial stages of the bombs
development and was present at the
detonation of the first a bomb at the
Trinity site. _Nobel prize-winner Hans
Bethe, leader of the theoretical physics
division in Los Alamos 1943 to 1946. _In
Los Alamos, in 1943, we had the problem of
assembling uranium to make an atomic
bomb. _Dr. von Neumann was a consultant to
the laboratory and visited us about
three times a year for a week or two at
a time. _There were two methods being
considered, one was to shoot the parts of
the bomb together by a gun and the other
method was the so-called implosion, in
which you surround the bomb material by
high explosive and then explode this
material, this explosive so that the
matter of the bomb would assemble in the
sphere. _In the beginning of the Los
Alamos laboratory, only the first method
seemed to be possible. _It was von Neumann
who told us and encouraged us to try the
second method and who gave us a lot of
information on similar work which had
been done under his supervision at the
Aberdeen Proving Ground in Maryland in
which shaped charges had been developed.
_He was very positive that an implosion
could be developed and he told us that
this would have added advantages for the
assembly which we had not realized. _One
32:57:
of the advantages which we had realized
was that the implosion would bring the
material together much faster and
therefore would prevent
detonation of the weapon before full
assembly. _Another advantage which he
pointed out was that the implosion might
squeeze the material and might thereby
33:51
increase …
(It's like, you can't make this up, you can say, work is based on support from people when it's not that matters, it's not about sympathy, it's about scientific facts, and how those scientific facts work.
When people try to make it seem like if, what works is when people work together while omitting scientific facts, they may well work against those facts together, and regress...)
the efficiency of the weapon.
_Even after this encouragement however, we
still found it very difficult to
assemble the material by implosion. _There
were experiments made under the
leadership of Dr. Kistiakowsky,
Harvard, to study the explosive method
without the uranium being around and
unfortunately they gave all sorts of
irregular shapes. _Well, this did not
trouble one von Neumann at all.
_He suggested to us that we use something
to focus the implosion, focus in a
similar way as light is focused by a
lens and this device in fact as been
called an explosive lens. _Afterwards, he
designed for us, some configuration of
explosive lenses which actually worked
and which was finally used in the
assembly that we used for the first bomb
in Trinity and afterwards in Nagasaki.
I took a taxi back home. I think it is fair to do so since I can’t walk uphill. I am a fast walker and my heart protests whenever I do so. I’m spending too much on the PC too. Tomorrow I have an appointment with the doctor. But it is not for my heart. I’ll go to a cardiologist after I go to a urologist first. I have symptoms of prostate issues.
I also have more analysis about that, and, how it can work better,
and, how it can help society more, related to business.
Not so abusive as they are and were, and intended to justify.

Ben Mezrich
There are 9 (movie) projects based on this.
They have enough to pay me and offer me better contracts, but,
want me to work for them on contracts, which they don’t want to contract before anti-trust.
So yes, more than 5 anti-trust cases against them, that shows how trustworthy they are and who put their trust in them and how, and how it’s misrepresented in other civilian courts, against military security.
Devest
To take away (a right or possession, especially an interest that has vested, such as the right to an estate). verb. 0. 1. To undress; strip.
(law) To take away, as an authority, title, etc., to deprive; to alienate, as an estate.
(law, intransitive) To be taken away, lost, or alienated, as a title or an estate.
To take away (a right or possession, especially an interest that has vested, such as the right to an estate).
It’s like the courts misrepresenting that I am ok when attacked +hoping that I don’t have to be against them as they seek to justify communication warfare against my family’s means of communication.
That is also why it’s not good to attack my work in electronic warfare against me as if the army wasn’t working on it, when protecting other programs and seeking to justify discrimination, against the army, and the army’s PR and HR.
It’s not 2 different things.
It’s facts which are sought and misrepresented to be 2 different things,
and create the exact same lack of cohesion.

Compared to how complicated they seek to make it seem to justify their systems while seeking to complicate others.
Thing went well with my doctor today… my blood pressure is good, my blood sugar is also good, I’ll be doubling on the medication for heart beat rate and we’re waiting on the result of a hormone test which was funny last time and might point to a organic cause for my high blood pressure. From what I’ve read, if I had that organic cause, then probably could be adressed with a medication for it and that would end my hypertension issues -but in the worst case scenario, there’s a need fro surgery, and in very bad cases, surgery which causes a chronic condition as tradeoff for avoiding organ damage from sustained hypertension and other effects.
Anyway, I’m happy that the drugs I take are working. Nighties lovelies!
Also: we didn’t had enough with cryptocurrencies, here come NFTs to waste even more energy in even more idiotic bubble economics…
This world needs urgently a few well-placed EMPs to wipe out energy-guzzling virtual idiocy.
It just shows that,
when some people are spoiled rotten and don’t have a general license to invest it wisely to protect their investment and those they pay taxes for,
that they get stuck with the money and can’t find the best way to invest their money, so that others profit more.
It’s the case of ,
what they call the ,
Zero-Sum Game, where the winner damages the loser ,
and, gets what the loser loses,
rather than to help him to thrive, and increase productivity.
For instance, for $69 million, I could produce the buyer art for over 3 generations and also digital arts from Mars and Titan.
