Brief history of the lie
11
Sep
People always tell stories in a way that their story seems a little better than it is, understand story
with h are not those of the books, but the facts for which there are artifacts, which in law is called instrumental proof.
One could go in classical antiquity, where we would find Diogenes to look for an honest man with a flashlight, I would say today In times of partisanship, which seem more fanciful football fanatics or some kind of fundamentalist belief, the truth is distorted everywhere, the recent fact in Brazil of the Bolsonaro stab had from conspiracy theories of a poorly executed crime, to whoever defended that it was all a staging, this said by intellectuals … amazing.
In recent history I find the thinker and poet of the Spanish Modernism António Machado y Ruiz, who wrote La verdad is also invented, so fake news are older, what has changed now is that intellectuals of little notoriety and ignorant people can also do so, and with it to gain a false reputation, but it is in fact notoriety.
Antonio Machado y Ruiz and encounter three very interesting phrases: “Never lose contact with the ground because only then will you have an approximate idea of your height”, and “if it is good to live, it is better to dream, and the best is to wake up” , but we should always wake up and sometimes this requires pruning, cuts would say, that the more mature the deeper.
I remember Cecilia Meirelles’s phrase: “I learned from the primroses to let myself be cut and to return always in full,” I also remember the Poem by Mário de Andrade, The Valuable Time of the Mature.
In the novel The Less Traveled Way, Scott Peck makes a statement to think: “It may seem less objectionable to fool the rich than the poor, but it is a mistake. Under the law, there are differences between committing a fraud in a business, handing over the fake income statement, using scrapbooks on a test, or saying at home that you stayed to work late when you are unfaithful. It is true that some mistakes are worse than others, but in reality they are not all lies and betrayals, “he would say in politics, to” believers.”
I remember once again Antonio Machado y Ruiz: “It is proper for men of medium-sized heads to invest against everything that does not fit in their heads,” those who invest the most against others have dogmatic truth, medium wisdom (if any) and arrogance to pounds.
I continue to invest in education that is neither dogmatic nor pragmatic, but the hermeneutics of the one who always doubts and is always open to the thought of the Other.
Why it is important to read Sloterdijk
29
Aug
I informed in the last post that besides the spheres of Sloterdijk, I have my own sphere, 
borrowed from Teilhard Chardin: the Noosphere. I read Sloterdijk´s Spheres only I that was published in Portuguese, of the others I have comments of the own author and of his readers and interpreters,
An answer I read recently from an interview with him gave me an important synthesis of my closeness to his thinking, when asked about what he expected from the academic world, he said ceremonially, “From the 19th century onwards (let’s think of Kierkegaard, Schopenhauer or Nietzsche), the world of philosophers is divided between those who, like me, seek an alliance with the media of their time (at that time, literature, today the press, radio and television), and those who do not do it, betting on the classic link between university and book publishers as their only cognitive biotope, “among many things I read, this is the coolest.
I do not bet on the media of social networks, blogs like the one I write to ten years, by fad or affirmation of my thinking, but because I think it is important to dialogue with what is now media, I refused some time, for example, to Twitter who is impulsive and angry.
Another point of contact is his view of the comfort zone, in the same interview published in the Folha São Paulo 2003 space Mais+, but which I randomly found on a website to re-read what influenced me at the time, which made me soon buy the book : Rules for the Human Park, published by brazilian Estação Liberdade, at the turn of the millennium, but soon stopped reading.
I only came back years later alerted by a student to the importance of his thinking.
This point of security, therefore, is not a zone of comfort, explains: “We are thinking how the human being architect the security of its existence. How does he live? How do you prevent future eventualities and catastrophes? How do you defend yourself? How do you integrate into your cultures, understood as communities of struggle? It is a paradigm shift: from philosophy to a general immunology, “that is, we seek a” place “to be sure, there is an analytic of the place, I would say in my analysis, in direct opposition to nihilistic and Kantian pragmatism.
A preview of Sloterdijk can not fail to be noticed in this interview, when predicting fascism in the USA: “From the point of view of media theory, fascism is monothematism in power. If a public opinion is structured in such a way that uniformity increases too much, we have a pre-fascist symptom, “there are several points on the planet with this symptom, and of course we can plunge into a new pre-war fascist era.
We can not fail to see this in positions in Latin America, and in Brazil in particular.
Hologram make success
26

Of unexpected firmness, a singer who is a three-dimensional hologram, Hatsune Miku conquered
crowds for her shows in various cities of Japan.
Hatsune fans, which is a holographic production simulating a 16-year-old girl, shake their luminous apathetic and shake during the show as if the artist were real.According to the Daily Mail report, Hatsune’s voice was created with voice samples from Japanese actress Saki Fujita. All these samples contain sounds that, when placed in series, become words and phrases.
Now the creators of the hologram can compose any song that the “avatar” will sing even without much elaboration.
Material can help quantum chips
08
Aug
Researchers at the University of Central Florida (UCF) have discovered a type of material that could be
used as a “building block” of quantum chips, consisting of hafnium, tellurium and phosphorus, Hf2Te2P.
According to UFC researcher Madabe Neupane, “Our discovery takes us one step closer to the application of quantum materials and helps us gain a deeper understanding of the interactions between various quantum phases.”
The material has more than one electron pattern that develops within its electronic structure, giving it a range of quantum properties. Neupane says that this material will increase computing power for large volumes of data on new devices and will considerably reduce the amount of power needed for power electronics.
The discovery has already attracted companies that are investing in research, Microsoft for example invested in its project called Station Q, the laboratory that is dedicated to the field of topological quantum computing, and Google has teamed up with NASA in an investment that works with quantum computing and artificial intelligence.
Because quantum phenomena need to be better understood so that electronics are totally replaced by photonics and quantum computation, computational scenario changes tend to change rapidly and continuously.
The discovery of Neupane’s lab is published in Nature Communications, and is a big step forward for this change of scenario.
The Geopolitics of Artificial Intelligence
06
Aug
Due to overzealousness with distortions of technology use, a delayed entry into the educational
and entrepreneurial sectors, some countries and industrialized nations begin to lose the foot of the technological race.
This has become more serious in the last two years, when technologies related to Artificial Intelligence (AI) and the Internet of Things (IoT) have become emerging.
Some authors speak of the fourth industrial revolution or Industry 4.0, where the issue is no longer the simple digital automation of existing jobs, but the total transformation of the model into digital, this means creating models of production, business, innovation and technological convergence in order to allow mass data processing and machine learning, this frightens by the social implications, but can not cause paralysis.
An emergency field that can help job creation is the “collaborative economy,” where Wikipedia and Uber are clearer examples, but there are many others. In the field of geopolitics it is easy to understand why the United States and China are winning this battle with ease, in addition to the economic and school structure for this, their transnational corporations in Europe, Russia and many other countries guarantee sustainable development and insertion in the market, but the the main issue is the non-negative criticism of the use of technologies and the understanding of the social aspects of this option.
A report by the Ecuadorian-British journalist Sally Burch, in the magazine América Latina en Movimento: integración en tempos de incertidumbre, 07-2018, shows the still incipient movement of this scenario in Latin America, without a serious political scenario.
Is it possible measure the evolution of AI ?
30
Jul
Now it seems that yes, it is necessary to establish more precise tests and exactly the accuracy
of these tests, but researchers of the Computer Vision Lab, of the Federal Institute of Technology of Zurich have created a test system (benchmark) that tests the performance of neural network´s platforms used to perform common Artificial Intelligence tasks, such as answering questions, finding certain data, and other smartphone applications already used in common neural network tasks.
The idea is to measure the performance of AI systems, such as and done on today’s computers and on applications useful in smartphones, which use Artificial Intelligence.
The basic plan + and measure the performance in the systems, as already done for some answers: time, locators, flights, restaurants, etc. and growing in complexity, which will make manufacturers and application vendors make their models more sophisticated.
The application calls AI Benchmark and allows, among other things, the comparison of the speed of AI models to run on different Android smartphones, punctuating performance, already found in the Google Play app.
The device that has the dedicated AI chip dedicated to some devices (at least with Android OS 4.1 installed already will be fast enough to do these functions.
Some applications may be more complex, for example sorting images with easy recognition and the ability to segment and improve photos, indicating that this type of application can grow and evolve to more complex applications.
Mixed Reality and Artificial Intelligence
24
Jul
Among the emerging technological innovations in the
year 2018 is Mixed Reality (MR) and Artificial Intelligence (AI) Microsoft CEO Satya Nadella already pointed to one of the future solutions, HoloLens, a RM + IA solution that helps users do things that were previously impossible.
Virtual Reality are environments that shut out the real world, Augmented Reality are digital content apn top of the real world and mixed reality digital content interacts with the real world.
The ability to merge the physical and digital worlds (the analogical concept applies to devices, but not to the real world), makes mixed reality allow to build experiences of people, places, and things regardless of their physical location and can interact digitally, I call this a multi-presence.
The companies promise, among them Microsoft, to incorporate HoloLens with more AI by building a Holographic Processing Unit or HPU. The mixed reality is avenging, in addition to the software available next to Windows 10, because experiences in the experiences of RA and RV, you can have the best of both worlds, RV is charming, but has a hypnotic effect, RA lacks realism.
Future experiences should incorporate sharing in the RM environment, a disruptive application of social media, with experiences that break down the walls of isolation and who knows, give a more educational dimension to the games.
The mixed reality can connect people in a meaningful, convincing and content-filled way, the multi-party will unite us, wait for a new application.
Make holograms real, fast and accurate

We have already mentioned the development of holograms in space without the
need for devices that recreate the artifacts, now it is possible to do them in an ultra-fast and very precise way. Scientists at the Lawrence Livermore American Laboratory in California have developed a technique that can create complex objects in seconds, we can say using Shannon’s sampling theorem for imaging, now being three-dimensional.
This technique creates the objects in layers simultaneously, the details were published in the journal Science Advances in December 2017, there are two really important innovations there, the possibility of creating real images in ultra-fast mode using a photosensitive resin recreating 3D printing with a powerful laser which hardens this resin making it a plastic.
This can also be done with metals using electron beam and a metal powder instead of the resin, so does not need the numerous supports required for 3D printers. LLNL engineer Maxim Shusteff, who leads the study, told New Atlas: “The fact that you can make totally 3D parts, everything in one step really overcomes a problem in additive manufacturing”, now holograms can return to material parts.
Another option would be live tissue bio-printing: “We made a good first attempt,” Shusteff said, “but we have not yet taken it to the limit of its performance, so the space is open to us and others to demonstrate what this approach is able to do. “living tissue bioprinting. “We made a good first try,” said Shusteff,
If 3D printing was already heralded as a revolution, this new technique promises to further accelerate this process
Butterflie´s effect and the little things
11
Jun
It seems that to change the world to change everything we must do great things, great projects
and in fact not really, small things can make a lot of difference, and the first thing we can change is ourselves, according to Plato’s phrase: “if wants to move the world, the first step will be to move oneself. ”
The butterfly effect, researched and defended by Edward Norton Lorenz, who even created the figure to the side, has double meaning first that he discovered that a butterfly’s wing beat could influence the climate, according to which the graph that created this effect physics heat convection model has the shape of the wings of a butterfly.
Lorenz was simulating global climate models on a computer, and executed another model that by removing some houses after the comma the processing time would be shorter and the result quit faster, in practice it slightly changed the process conditions, and the results were quite divergent.
This means in practice that small actions and interventions in phenomena can along a course influence them deeply, which gives us hope because so little that we do correct, honest and ethical inspiration can in the future dramatically change things, Of course, other people will need to do small things.
A personal experience was to lose a loved one by suicide, made me think a lot wondering what could have happened to that person, after much suffering a psychologist explained to me that not only social and emotional but also genetic, physical and emotional factors could determine the action of that person.
Thinking in the positive sense we can make small gestures, a child asked me to play ball with her, I was hurrying, I stopped and I played for five minutes with her, there the neighbor of a building that saw me with a bag in hand, told me can go now I play with the kid (kids in Portugal).
Also thinking about Brazil, the enormous suffering with all negative social and political events, we must try to see small actions that can be done, to make people aware and to listen when someone is very convinced of their point of view.
I see that Portugal left the crisis winning and recovering the optimism as a people, they did not lose hope, although the crisis has reached many people and still there are reflexes, but it is noticeable the improvement.
Oral, written and electronic history of Shannon
21
May
There are good reasons for a certain lack of knowledge and criticism, often unfair, to Claude Shannon.
There is a rare interview in July 1982 by Robert Price, curiously called “Oral-History” in which he states:
“Well, back in ’42…computers were just emerging, so to speak. They had things like the ENIAC down at University of Pennsylvania…Now they were slow, they were very cumbersome and huge and all, there were computers that would fill a couple rooms this size and they would have about the ability of one of the little calculators that you can buy now for $10. But nevertheless we could see the potential of this, the thing that happened here if things ever got cheaper and we could ever make the up- time better, sort of keep the machines working for more than ten minutes, things like that. It was really very exciting.
We had dreams, Turing and I used to talk about the possibility of simulating entirely the human brain, could we really get a computer which would be the equivalent of the human brain or even a lot better? And it seemed easier then than it does now maybe. We both thought that this should be possible in not very long, in ten or 15 years. Such was not the case, it hasn’t been done in thirty years.”
The written work of Claude Shannon is well known, it is in his main work Mathematical Theory of Communication, which begins with an article with the same name published in the magazine of Bell Laboratories in 1948, and that has a revised version and corrected in the site of the Department of Mathematics, Harvard.
Finally, the great contribution of Shannon, besides that its presented diagram is always incomplete because they take from him the source of information and the destination of the information, and this makes the information “without signification” and without sense.
But his great contribution is in fact the information in the artifact, what are the limits of “noise” (not only this) but he himself states in his work that he will deal with information in a strict sense, that is, in the artifact
