Hello..
 
 
 
Here is my thoughts of my political philosophy about Globalization and nationalism..
 
Read the following article about economic nationalism:
 
Rise of Economic Nationalism and Its Implications
 
https://www.lewisu.edu/experts/wordpress/index.php/rise-of-economic-nationalism-and-its-implications/
 
Notice that it says the following:
 
"Countries benefit with cooperation between countries to mutual benefit, becoming too nationalistic at the expense of its partners is counterproductive. It is an approach that creates conflict. Being more nationalistic tends to be a zero sum game in an increasingly interdependent world economy, where countries depend on other countries for their economic and political and national security well being. When companies cooperate, they can become more competitive. When they are more competitive, they hire more workers, pay higher salaries, and otherwise contribute to economic growth. Economic nationalism is a bad policy."
 
And now about Global optimization since i am talking about it below:
 
Global optimization is distinguished from local optimization by its focus on finding the minimum or maximum over the given set, as opposed to finding local minima or maxima.
 
So as you are noticing that nationalism is an optimization or local optimization that lacks on global optimization, so it is not a good optimization, since it lacks on collaboration or it lacks on cooperation that permit you to become competitive. This is the kind of optimization that i am talking about below when i am talking of Donald Trump and his governance that is nationalism that lacks on global optimization, also you have to know how to achieve long-term financial stability, it is also by not thinking just the short-term by for example wanting to too quickly getting rich, but it is also to think about the long-term by for example setting clear goals and by being the right education that permits you to be competitive, and this is also related to antitrust laws and envirenmental laws and Minimum Wage Laws, so i invite you to read all my following previous thoughts so that to understand:
 
Read my following thoughts about slavery and about black
lives matter:
 
https://groups.google.com/g/comp.programming/c/XjVH_kpC9_g
 
And here is what i said about Donald Trump governance and more:
 
Read the following interesting article to notice that Donald Trump
governance is nationalism:
 
'I am a nationalist': Trump's embrace of controversial label sparks uproar
 
https://www.usatoday.com/story/news/politics/2018/10/24/trump-says-hes-nationalist-what-means-why-its-controversial/1748521002/
 
 
I think when you are smart you will quickly notice that Donald Trump
is not smart, because nationalism is not good for "business", read my above writing to notice it, also Donald Trump lacks some very important requirements such as knowing how to be Diplomacy so that to attract confidence and respect, also Donald Trump is simple minded in his way of governing since in our today world, governance has to be apt at knowing not only how to manage a country but how to efficiently manage our world, Donald Trump is lacking on those requirements, so we have not
to waste our time with Donald Trump since nationalism is a loser in our today world, and i predict that Donald Trump will lose in the next elections.
 
Look at the following old history of Quebec FLQ crisis in Canada, and
notice that FLQ were "nationalists" in Quebec:
 
https://en.wikipedia.org/wiki/Front_de_lib%C3%A9ration_du_Qu%C3%A9bec
 
And look at the following video about this crisis brought by Quebec nationalists in Canada:
 
OCTOBER CRISIS OF 1970 QUEBEC - FLQ
 
https://www.youtube.com/watch?v=pF7s6pir_gI
 
So as you are noticing that Canada was a country that was
like a form of a "miniature" Globalization, compared to the actual Globalization, that had to transcend nationalism, and i think
that prime minister Joseph Philippe Pierre Yves Elliott Trudeau of Canada was a visionary that has seen the benefits of the our today model of like seeking a balance between competition and collaboration or cooperation of our today Globalization so that to be competitive(read my below thoughts to know more about it), so as you are noticing that nationalism brought problems and was lacking in efficiency, i think USA is having the same problem with Donald Trump that is like a "nationalist" that is creating problems like the old nationalist FLQ of Quebec, i think that Donald Trump governance is like archaism of nationalism.
 
Am i a communist ?
 
No, and i am for Democracy, but you have to know more about my thoughts
on political philosophy, so read all my following thoughts so that to understand how i think and so that to understand my kind of personality:

"For many economists, however, the trade deficit has been scapegoated, and they argue that the trade deficit is not itself a problem for the U.S. economy. That's because a larger trade deficit can be the result of a stronger economy, as consumers spend and import more while higher interest rates make foreign investors more eager to place their money in the United States."
 
"The Peterson Institute's Hufbauer counsels, it is better to recognize that the trade deficit is neither all good or all bad, but rather consists of trade-offs: the U.S. economy benefits from foreign goods and investment even as a high deficit displaces some workers and adds to the national debt."

Also I invite you to read the following interesting paper:

https://www.nist.gov/system/files/documents/2017/05/09/2013-competitiveness-innovation-productivity-clearing-up-confusion.pdf
 
 
More philosophy about capitalism and globalization..
 
 
I have just read the following:

https://www.independent.co.uk/news/business/news/cbi-government-uk-economy-most-competitive-2030-carolyn-fairbairn-a7687401.html
 
 
And notice that it says the following:
 
"It is paramount that the Government prioritises innovation.
"Our competitive advantage depends on our ability to develop and commercialise new ideas as well as the ability of businesses to adopt technology and become more productive," the organisation writes.
 
So as you are noticing that it is an "abstraction" of what must be a competitive economy in UK, but if you are smart you will notice
that we have to be "positive" because i think that capitalism and
globalization are good things, since to go further into the details behind the abstraction, i invite you to read my following thoughts
to also understand why capitalism and globalization are good things:

This is why a good solution is in my following writing
, read below about it in my writing about UK:

And it is related to my following thoughts:
 
I just said before the following:
 
---
 
More about "democratization" of finance..
 
This "democratization" of finance is also for Research and Development (R&D))..
 
And look at the following "democratization" of finance so that to understand:

About democratization of digital technology and technology and Research and Development (R&D) investment
 
This is also why i said the following:
 
Look at the following interesting video:
 
Can South Korea lead global innovation in Fourth Industrial Era?
 
https://www.youtube.com/watch?v=XUw8gCShEcI
 
 
But i think that this minister of education, science and technology
of south Korea looks somewhat archaic since he is not taking correctly
into account the democratization of digital technology and Technology that permits you to economically grow very rapidly and much cheaply than using "expensive" Research and Development (R&D) investment, so i think that he is not correctly adapting to the realities, because the economic realities have very much changed, since also our era of globalization has been characterized by the democratization of technology, democratization of finance, and democratization of information.

Here is more proof of what i am saying:
 
 
2. Question: What do you mean by "Democratizing Innovation"?
 
Eric von Hippel:
 
The tools for designing high-quality innovations are getting so cheap and so ubiquitous that individuals can innovate for themselves at a steadily higher quality and at a steadily decreasing cost. These sophisticated modern tools are computer-based, and require relatively little training and practice. As a result, even hobbyist users find they can use them to design new products and services.

More political philosophy about globalization and free trade..
 
Globalization causes some problems to lower class and some of the middle class in western countries, but i think that we have to compensate those losers by for example doing this and doing it "better":
 
Countries that have unemployment benefits provide assistance to people who have lost their jobs. Some of those people will have been affected by competition from abroad.
 
The United States has a programme that is specially targeted for people who lose their jobs as a result of imports, called Trade Adjustment Assistance.
 
Also globalization causes the rich to become much more rich and it is what we call the problem of unequal distribution of income and
opportunities(read my thoughts below about it)..

As you have noticed that the most important by far that creates like a
great empire like USA are good education and innovation and technology
and the most important by far that avoids the decline of like a great
empire like USA are good education and innovation and technology, and
innovation and technology permit you to be good at competitiveness and
they permits you to export much more, but it is "not" sufficient, for
example Germany that is good in education and innovation and technology
must not cause economic problems to its consumers of other countries of
Europe, it is by logical "analogy" like Fordism that is: mass production
of inexpensive goods coupled with high wages for workers, what do i mean
is that for example Germany or USA that are good in innovation and
technology must know how to take care of wages of there consumers or how
to take care of the economies of the countries of there consumers so
that to be able to sell there products and services, so we have like to
globally maintain a kind of "balance", i mean that so that to be like a
great empire like USA, you have to know how to "tune" it correctly by
ensuring that consumers globally have sufficient quantity of power or
money to buy your products and services.
 
But you have to also understand that this taking care of wages is also
Globalization and trade that have increased real wages, please read

"The protesters claim that globalization is bad for poor people in poor
countries. A large body of evidence, however, suggests the
opposite—though clearly globalization can result in unsettling
experiences for many who live in the developing world. My recent
research with Nancy Birdsall and Stefano Pettinato suggests that
globalization has brought substantial benefits and opportunities for
upward mobility for many low-income individuals in the emerging
economies. Yet these same opportunities entail new vulnerabilities and
new risks for others."

And more about globalization..
 
1- Globalization has created new opportunities for firms to develop
business models and offerings that have a higher intensity of R&D,
innovation and capital. Many of the goods and services that have entered
the market over the past decades have exactly those features, and
without globalization, firms would have been forced to continue with
business models that work with a smaller volume of sales. Firms have
been able to specialize more than before and, as a consequence, human
capital and the share of skilled jobs in the economy have grown
remarkably. Today, advanced economies have a greater share of
better-paid and better-skilled jobs than ever before.
 
2- Globalization has increased real wages for people in Western
economies by making products cheaper or reducing the pace of price
increases. If the typical goods that every household purchases had
followed domestic rather than international price developments,
consumers would have been poorer and saddled with products of lower quality.
 
3- Globalization has made significant contributions to productivity
growth and, as a consequence, further raised living standards.
Globalization has been particularly important for enabling new
technology to spread fast across markets. In the long term, it is the
speed of technological improvement that sets the pace for how richer
societies get.
 
However, trade and investment are not growing fast anymore, and there is
much suggesting that the decline in trade and investment growth is one
explanation to the failing dynamism of Western economies. While some
appreciate the decline in the growth of globalization, those who care
about the prosperity of a society should deplore it and make efforts for
the world economy to return to high levels of trade growth.
 
Read the following study to know more about globalization:
 
The Economic Benefits of Globalization for Business and Consumers

More of my philosophy about complexity and productivity and quality..
 
I am a white arab, and i think i am smart since i have invented many scalable algorithms and algorithms, and i think i am a philosopher, so i have just talked yesterday in my philosophy about the meaning and purpose of life(read my thoughts about it below), and today i will
speak more about complexity and productivity and quality..
 
So i will ask a philosophical question:
 
How to manage efficiently complexity ?
 
I think you can manage complexity by the "divide and rule" approach
to management, which also leads to hierarchical division of large organisations, or wich also leads to the Division of "labour",
you can read more about the Division of labour here:
 
https://en.wikipedia.org/wiki/Division_of_labour
 
Also you can manage complexity by using constraints, such as laws, road rules and commercial standards, all of which limit the potential for harmful interactions to occur, also you can manage complexity by
using higher layers of abstraction such as in computer programming,
and we can also follow the efficient rule of: "Do less and do it better" that can also use higher level layers of abstraction to enhance productivity and quality, this rule is good for productivity and quality, and about productivity: I have also just posted about the following thoughts from the following PhD computer scientist:
 
https://lemire.me/blog/about-me/
 
Read more here his thoughts about productivity:
 
https://lemire.me/blog/2012/10/15/you-cannot-scale-creativity/
 
And i think he is making a mistake:
 
Since we have that Productivity = Output/Input
 
But better human training and/or better tools and/or better human smartness and/or better human capacity can make the Parallel productivity part much bigger that the Serial productivity part,
so it can scale much more (it is like Gustafson's Law).
 
And it looks like the following:
 
About parallelism and about Gustafson's Law..
 
Gustafson's Law:
 
• If you increase the amount of work done by each parallel
task then the serial component will not dominate
• Increase the problem size to maintain scaling
• Can do this by adding extra complexity or increasing the overall
problem size
 
Scaling is important, as the more a code scales the larger a machine it
can take advantage of:
 
• can consider weak and strong scaling
• in practice, overheads limit the scalability of real parallel programs
• Amdahl's law models these in terms of serial and parallel fractions
• larger problems generally scale better: Gustafson's law
 
Load balance is also a crucial factor.
 
So read my following thoughts about the Threadpool to notice that my Threadpool that scales very well does Load balance well:
 
---
 
About the Threadpool..
 
I have just read the following:
 
Concurrency - Throttling Concurrency in the CLR 4.0 ThreadPool
 
https://docs.microsoft.com/en-us/archive/msdn-magazine/2010/september/concurrency-throttling-concurrency-in-the-clr-4-0-threadpool
 
 
But i think that both the methodologies from Microsoft of the Hill Climbing and of the Control Theory using band pass filter or match filter and discrete Fourier transform have a weakness, there weakness is that they are "localized" optimization that maximize the throughput
, so they are not fair, so i don't think i will implement them, so then you can use my following invention of an efficient Threadpool engine with priorities that scales very well (and you can use a second Threadpool for IO etc.):
 
https://sites.google.com/site/scalable68/an-efficient-threadpool-engine-with-priorities-that-scales-very-well
 
And here is my other Threadpool engine with priorities:
 
https://sites.google.com/site/scalable68/threadpool-engine-with-priorities
 
 
And read my following previous thoughts to understand more:
 
About the strategy of "work depth-first; steal breadth-first"..
 
I have just read the following webpage:
 
Why Too Many Threads Hurts Performance, and What to do About It
 
https://www.codeguru.com/cpp/sample_chapter/article.php/c13533/Why-Too-Many-Threads-Hurts-Performance-and-What-to-do-About-It.htm
 
Also I have just looked at the following interesting video about Go scheduler and Go concurrency:
 
Dmitry Vyukov — Go scheduler: Implementing language with lightweight concurrency
 
https://www.youtube.com/watch?v=-K11rY57K7k
 
And i have just read the following webpage about the Threadpool of microsoft .NET 4.0:
 
https://blogs.msdn.microsoft.com/jennifer/2009/06/26/work-stealing-in-net-4-0/
 
 
And as you are noticing the first web link above is speaking about the strategy of "work depth-first; steal breadth-first" , but we have to be more smart because i think that this strategy, that is advantageous for cache locality, works best for recursive algorithms, because a thread is taking the first task and after that the algorithm is recursive, so it will put the childs tasks inside the local work-stealing queue, and the other threads will start to take from the work-stealing queue, so the work will be distributed correctly, but as you will notice that this strategy works best for recursive algorithms, but when you you iteratively start many tasks, i think we will have much more contention on the work-stealing queue and this is a weakness of this strategy, other than that when it is not a recursive algorithm and the threads are receiving from the global queue so there will be high contention on the global queue and this is not good. MIT's Cilk and Go scheduler and the Threadpool of Microsoft and Intel® C++ TBB are using this strategy of "work depth-first; steal breadth-first". And as you are noticing that they are giving more preference to cache locality than scalability.
 
But in my following invention of a Threadpool that scales very well i am
giving more preference to scalability than to cache locality:
 
https://sites.google.com/site/scalable68/an-efficient-threadpool-engine-with-priorities-that-scales-very-well
 
Other than that when you are doing IO with my Threadpool, you can
use asychronous IO by starting a dedicated thread to IO to be more efficient, or you can start another of my Threadpool and use it for tasks that uses IO, you can use the same method when threads of the my Threadpool are waiting or sleeping..
 
Other than that for recursion and the stack overflow problem
you can convert your function from a recursive to iterative
to solve the problem of stack overflow.
 
Other than that to be able to serve a great number of internet connections or TCP/IP socket connections you can use my Threadpool
with my powerful Object oriented Stackful coroutines library for Delphi and FreePascal here:
 
https://sites.google.com/site/scalable68/object-oriented-stackful-coroutines-library-for-delphi-and-freepascal
 
---
 
And enhancing productivity is also related to my following powerful product that i have designed and implemented(that can also be applied to organizations):
 
https://sites.google.com/site/scalable68/universal-scalability-law-for-delphi-and-freepascal
 
Please read the following about Applying the Universal Scalability Law to organisations:
 
https://blog.acolyer.org/2015/04/29/applying-the-universal-scalability-law-to-organisations/
 
Yet more philosophy about quality control and quality..
 
So first you have to define quality(read below about it) and second
you have to construct quality and third you have to control quality.
 
So, I have just read the following about the Central Limit Theorem
(I understood it), i invite you to read it carefully:
 
https://www.probabilitycourse.com/chapter7/7_1_2_central_limit_theorem.php
 
 
So as you are noticing this Central Limit Theorem is so important
for quality control, read the following to notice it(I also understood Statistical Process Control (SPC)):
 
An Introduction to Statistical Process Control (SPC)
 
https://www.engineering.com/AdvancedManufacturing/ArticleID/19494/An-Introduction-to-Statistical-Process-Control-SPC.aspx
 
Also PERT networks are referred to by some researchers as "probabilistic activity networks" (PAN) because the duration of some or all of the arcs are independent random variables with known probability distribution functions, and have finite ranges. So PERT uses the central limit theorem (CLT) to find the expected project duration.
 
So, i have designed and implemented my PERT++ that that is important for quality, please read about it and download it from my website here:
