Holographic Transmission 2022 Football Cup

19 Aug

This is what Japan promises, already in 2015 they had bought this right without even knowing if the technology would be mature, with the 5G internet and the possibilities of drones that map the movements of each player in the field, let us remember that the idea Player movement has been possible for a long time, with games available every cup.

As the Qatar Cup is being questioned, Japan has already proposed to host saying that the 2002 World Cup, which by the way Brazil was Champion, has proved the infrastructure capacity and qualities of football stadiums, now launches as an alternative to Qatar .

Suminori Gokon, chief director of the Japanese World Cup committee, said it was time to return something like a return to the participating countries, as well as entertainment, with the possibility of a free point view that allows fans to navigate the field. Choosing the field of vision that I have from the game, I am already imagining a VAR with these resources, would reach the body of the player to observe the contact in a foul.

It proposes an augmented reality not yet known which is the possibility of not only capturing the lines by lip reading, they also translate the lines in several languages ​​(photo), of course the mouth in hand to speak will become a total craze on football fields.

In South Africa the president made an appearance using hologram technology to be present at two events at the same time, recently Portuguese TVI used the pivot journalism José Alberto Carvalho to make a Vodafone promotional call on the premises Vodafone Paredes de Coura, more than 400 km from the studio, due to the speed of 5G transmission, it is not possible to notice the delay in speech that he was making with the other caller at a distance.

Below the video where Japan purports to be the holographic broadcast promoter of the 2022 World Cup:

 

 

Qutrit, teleportation and philosophy

12 Aug

Two teams independently managed to teleport quantum particles called QuTrit (quantum trit), with a few days difference that can be said to be simultaneous.
Both are awaiting review of the peer review process for their publications to come out and receive “invention” credits.
A qutrit is similar to the qubit (the well-known quantum bit), except that instead of binary beings (0 and 1) they are classic ternary systems, which because they have the possibility of a third state, say 0, 1 and 2 can transform more information than qubit.
This surpasses what in philosophy, especially the idealist in which we can have only A and B, and there can be no contradiction, in this case not exactly contradiction, but a third state.

The communication system used is the HD-BSM (High Density Bell State Measurement).

Although quantum systems are much less noisy (subject to change by the environment) than digital electronic systems, qutrit are even less noisy and thus more reliable.
Teleportation means that information goes from point to point without a “medium” meaning that it will be less subject to interception and thus more reliable in terms of quantum cryptography.
The two groups claiming to have a healthy scientific rivalry are the group led by physicist Guang-Can Guo of researchers from the University of Science and Technology of China, and the other led by Anton Zeilinger of the Austrian Academy of Sciences, and there is already a version in analysis of the articles on the subject, the so-called pre-print, and were published respectively on April 28 (preprint) and June 24 (preprint).

 

Industrial scale qubit chip

21 May

The quantum chip (qbit or quBit) can now go on an industrial scale, a team of researchers from Denmark and the US announced last month that the technology is ready.
The problem was to scale up in such a way that computers could use chips, so far the qubits’ quantum computing was not robust enough to operate in noisy environments on a full computer.
Another problem was scale production, out of specialized laboratory and produced in conventional factories, they had to work with the semiconductors and normal circuit boards, with a combination of the semiconductors of conventional chips with aluminum and aluminum arsenide, the part industrial revolution is solved.
The team is led by Professor Antonio Fornieri, who has built a quantum memory chip and promises that quantum computers can now be produced in scale. the most resilient qubits by a combination of a semiconductor, the Indian arsenide, with a superconductor, aluminum, in a planar device, called the so-called Josephson junction, capable of treating Majorana quasi-particles.
Majorana quasiparticles are zero-mode fermions, which emerge on the surface of topological superconductors, which function as fault-tolerant and noise-free qubits.
The teacher Fornieri said: “Our prototype is a significant first step in using this kind of system to make quantum bits that are protected against disturbances.” “We still need some adjustments at the moment – we can improve design and materials, but it’s a potentially perfect structure.”.
The article was published in Nature and is authored by Fornieri and his team: Antonio Fornieri, Alexander M. Whiticar, F. Setiawan, Elias Portolés, Asbjørn CC Drachmann, Anna Keselman, Sergei Gronin, Candice Thomas, Tian Wang, Ray Kallaher, Geoffrey C. Gardner, Erez Berg, Michael J. Manfra, Ady Stern, Charles M. Marcus, Fabrizio Nichele, Evidence of Topological Superconductivity in Planar Josephson Junctions. Nature Vol .: 569, pages 89-92.
The following video explains the who Qubits working:

 

The informational impact

08 May

Society, information abundance, information turnaround and other appeals to the novelty that arose not with the internet, but with the computer and the possibility of handling the data in volume (Big Data) certainly brought a new perspective.

Anyone who wanted to understand eighteenth-century society should study the industrial revolution and its impact on manpower and the production of serial products, today anyone who wants to analyze contemporary society cannot lose sight of the volume of data they are produced to try to make this volume accessible to society.

But it is not so, because together with this volume came by previous process, it is only to check with history, not the romantic dreamed by idealists, but the real one and to realize that the problem of both Information in volume and depth, made it difficult to digging and knowing what is essential.

We have already posted here Karl Kraus, who complained to journalists in the midst of the threat of a second world war because of misunderstood news highlighting only interests. In an interview with the newspaper El Pais, Peter Sloterdijk also warned that “it is difficult to think of contemporary society,” Byung Chul Han his disciple alert to “active vita” (Chul-Han)

The phenomenon we witnessed in which information became practically a commodity, started with the digital model of Shannon (photo) and the Turing machine in the 1930s, and accelerated with the construction of modern computers.

What we witnessed and did not always participate in an “active” and reflexive way, able to elaborate thinking about information, is the fragmentation of knowledge accelerated by new gadgets, but which was initiated by a crisis in the thinking of Western society, which only deepened over the years, its initializing in modernity.

The Movie The game of imitation (2015) illustrates the life of Alain Turing and his theory:

 

 

 

Alexa: between complaints and new kit

15 Apr

In the midst of allegations of invasion of user privacy, use of data to augment Amazon’s personal assistant: Alexa, the company launches a kit that can further enhance the development of its “intellectual” ability the Alexa Skills kit ( ASK).
The claims made by Bloomberg were that employees would be listening to conversations and using private information, the company defended itself by saying that “an extremely small sample” was used and that its employees did not have access to identification.
The goal would be to help users “better understand their requests and ensure the service works well for everyone,” the machine learning and deep lerning functions are used.
The company of Jeff Bezos began to carry out tests in Portuguese, and already released the kit to reach the market of the 3rd. the most widely spoken language on the Internet, developers will be able to develop the “skills” of the voice assistant and thus expand the ecosystem of the product in Portuguese.
The idea is to anticipate the hardware products that will be released to Alexa, incorporating the Internet of Things (IoT) and when they were released already have developments.
The Amazon testflight, as it is known, has versions for Apple and iOS, but free software developers non Vasile, there are development alternatives.
In addition to releasing the kit, Amazon also stated on its website that enterprises: Bose, LG and Intelbras are development products.
This is basic introduction to ASK:

 

The Web turned 30

13 Mar

Still confuse the Internet, the Web and the Network, although they may be superimposed, they are different aspects that united the world, the pessimists say worse, the optimists say it points to the future, the realists say it is a new time with difficulties and facilities, well used will be promising for the future.
On March 9, at CERN where Tim-Berners Lee worked when he made a proposal for an Internet interpreter called and used the term web (not net), the idea of his original article was an ease of handling scientific texts online that at the very moment they were written were ready to be read, which bloggers and tweeters do today, but that was Web 2.0 in 2005.
In Geneva at CERN Berners-Lee met with Robert Cailliau, a computer science engineer who was not mentioned at all, but it was in fact that he made the first hypertext system, they were joined by other experts to discuss the present and future of the World Wide Web, or Web. 
The event, called Web @ 30, was opened yesterday (12/03) by CERN General Manager Fabiola Gianotti, in collaboration with two organizations founded by Berners-Lee: the World Wide Web Foundation and the World Wide Web Consortium ( W3C), CERN has recently restored the first website and online brower, shown at the Hackathon event (February 11-15, 2019). 
Security issues, free internet maintenance policies, governments and business structures want their control and in some countries it is not a free service, fake news and others were topics for discussion. 
A promising theme for the future is the SOLID project, we have already posted a post on it, it is in full development with the collaboration of MIT researchers, but the expectation is high and there will still be a lot of expert work to give the world a reliable Web.
Suhayl Khan showed how to access the browser in online mode using technology from the 1960s (when there was only internet and with few facilities) (Video: Suhayl Khan):

 

Foldable smartphone, novelty?

12 Mar

The Mobile World Congress fair held last week in February in Barcelona brought the folding screens as a novelty, foldable in half only, and whose novelty is to improve the user experience, both joining the two halves, as separating the application and the set of them in two screens, creating a new, now active “window” experiencie, now in two screens.
The Huawei Mate X comes and soon Samsung will launch the Galaxy Fold (April 26), both foldable but without fit in the pocket.
It cost billions of euros development, the appeal is not that great and the price may be prohibitive at least in the first instance for the descent middle class pockets.
The options that are likely to attract the markets are the Xiaomi Mi 9 Launches and Samsung Galaxy S10 Plus, which tend to perform most of the scenarios in use, but with applications that make it easier to use games and Google Play Store faster, and has built-in artificial intelligence capabilities that help improve photos and security.
The Galaxy S10 brings a special 12 MP sensor with wide-angle lens and a 12-megapixel lens with a telephoto lens giving a 2x optical zoom, and the third with a lens of 123º of opening.
The launches bring the most modern chips on the market, Qualcomm’s Snapdragon 855, although in Brazil for cost reasons, at least the Korean, will leave with the Exynos 8920.
The US sale price is $ 999.99 (about 4 thousand reals in Brazil), while the Xiaomi Mi 9 about 450 euros, something around 2 thousand reais, that is, half.
In Europe are available versions with memory of 6, 64 or 128 GB, the folding for now only ads at prohibitive prices: 2 thousand euros, or 8 thousand reais, I think that some manufacturers that will launch with two screens will do well, the experience is almost the same.
The video below gives a sample of Huawei’s Mate X:

 

What characterizes the changes today

07 Mar

In order to change social structures, it was necessary for a long time to mobilize formal structures capable of reacting to structures of power that oppressed the feeling of change in various ways, feeling and emotion were always present, saying that they are emotional now is a mistake, it is due the old idealist separation between objective and subjective motivation.
The virtual is real are coming, not just because of the speed, intensity and quantity of devices able to connect people almost permanently regardless of distances.
The virtual depends on the updating, and therefore is opposite to the current and not the real, even in the space of the imaginary, where the cultural cosmologies are composed, the virtual is close to a cultural real.
What is changing now is that it is possible through the use of communication to establish real (not just virtual) links between people and to mobilize them for a reaction to structures of domination, and those who are unaware that information is available on the net and can being hacked, the last one is the football leaks that shook the world of soccer, by the denunciations of the Portuguese Rui Pinto.
As Manuel Castells explains, social movements have always had at the origin the feelings of shared injustice and indignation, what changes today is that these networked technologies allow a collective subject, but of course this can be negative.
Castells explains that this is not a utopia, but what is happening, and that technology is not decisive, but is influential, as McLuhan says by changing the means and changing communication, change social relations.
The structures of the old state, groups of religious and ideological polarization weaken, and a more real society comes to light than that whose state, for its vices and its virtues appear, the vehicles of communication all controlled by editorial groups and the old ones oligarchies dominated and retained power.
Castells explains this in a 2013 video:

 

Virtual reality, vision and clearing

28 Feb

Mankind has always used shadows to make paintings and to open glades other than for its contemporaries, at least for future generations and for their fellows, the cave paintings, now with the Cavern of Chauvet dates back to 32 thousand BC, can demonstrate this. There are a few ways of writing, and some new ones have been thought by Vilém Flusser, who wrote while speaking of the masks: “The software artist’s mask has not been available for a long time. There may be different levels of creativity. Maybe being a writer will be different from being a software expert, and then perhaps inventing the writer. In this respect, we have prejudices with which to break.” (Flusser, 2014, p.191).

Since Plato’s Myth, the idea of ​​a clearing was theorized by mankind, it is different from cave man because it involves a level of intentionality and creativity as Flusser wants, and more recently the Enlightenment is nothing more than this quest. Heidegger drew attention to the world view, the Weltanchauuun, a set of cultural values ​​that build our vision. The central problem of the clearing is that it can be linked to the senses, so it was for the empiricists, but the fourth dimension (already proven) and other superior ones (that may be) give a new dimension of what this vision is now, with virtual realities, increased and mixed this may be even higher.

There will be no lack of fatalistic and apocalyptic, lacking Flusser’s humility, but immersion is already under way with mixed reality, for which various environments are available to the conventional public, since the word lay can be misinterpreted, 3D viewers and software for creation are available in environments made available by tablet and smartphone manufacturers.

It’s true that just as the new media: internet, web, chats, Pinterest and videos have changed our vision of how to see things, does not mean that changed the world view, but seeing beyond what the senses see we are at least expanding our “sensations,” as Marshall McLuhan wished, in explaining the passage of circular houses, explains by giving an aid to anthropologists: “In the same way, the visualist may not see much difference between the TV film, between a Corvair and a Volkswagen, because the difference lies not between two visual spaces, but between a tactile space and a visual.” (McLuhan, 1964, p. 145).

Flusser, V. (2014) Comunicologia: reflexões sobre o futuro. São Paulo: Martins Fontes.

McLuhan, M. (1964) Understanding media: the extensions of Man. New York: McGraw-Hill. 

The same thing happens now with virtual reality, the augmented and the mixed, nor the moment with the greatest potential to become popular, because what changes is not the field of vision, but the empathic relationship that these media possess, adults may not understand, but to young people this is immediate. An entrepreneur and virtual reality expert explains this empathy, Thong Nguyen’s TEDx is very interesting:

 

 

 

Markham in Canada: smart city

13 Feb

Ignorance of the benefits that smart and rational use can bring to many cities make many public policies inefficient and unnecessarily expensive, a serious problem is the infrastructure to monitor cities. In a partnership project, Bell Canada and IBM Canada want to make the city of Markham,
Ontario in Canada, with approximately 330,000 inhabitants, a model for using networks to make it a “smart city,” according to the Financial Post
The city government will use Bell’s broadband networks and IBM data analysis, collecting sensor data placed throughout the city to decide on investments in various aspects of infrastructure: pipeline leaks, flood-prone regions (Lake Ontario), problems that arise in storms, effective use of energy and tracking.
The projects do not fail to include social improvements and ecological aspects that also depend on the good use of technology and energy,
Many environmentalists are unaware that the results of Medellin were also achieved using Smart Cities concepts, being the first case in Latin America.
South. Similar trials and projects are being conducted in Canada and other parts of the world in view of which a number of multi-provider services may be preparing services that best cost and prevent service disruption.
