The Truths and Myths of Deep and Dark Web

01 Oct

The internet is the physical medium that emerged in the 70’s, and after 1990 it became a layer of code over the internet that makes content data available to users, at the beginning of Web 2.0 it also became available for content production. by users.
The Deep and Dark Web are hidden parts of the Web where only through specific networks one can access them which are i2P, Freedom, Osiris and a few others.
The best known is the Onion network, which precisely resembles the layers of the onion whose interior are layers and layers that do not reach a core, it has a special Router which is the TOR (The Onion Router), which even without specific knowledge can if you use them, but only the deep web, the dark web is harder to access and has many pitfalls.
Recorded Future says it does not represent 1% of the Web, which does not mean that there are no serious crimes and dangers in these digital environments.
These environments where anonymity is important make it a much more delicate task to investigate crime and danger to users, and care must be taken not to damage data, facilitate crime and even damage equipment.
In the count of domains accessible to the Recorded Future site found less than 0.005% were “live” sites, I mean they were used someday, but the content is disabled.
Of the 55,000 Onion network domains found, only 8,400 had something active (15%), so the popular iceberg metaphor (pictured) is not very true, as the visible part is much larger than the submerged one.
Today there are 200 million unique and active surface web domains, while Onion network sites by the number presented, which makes it 0.005% the size of the World Wide Web, according to the study presented.
Thus the benefit caused by the Web is vastly greater than the dark side, which being a crime must be investigated and fought.
The serious cultural, human and social crisis we are going through has a connection with all media and media, but it is not the Web that is a great evil, the great crisis.

Artificial Intelligence and Diagnostic Aid

18 Jun

Artificial Intelligence and Diagnostic Aid Exams for tomography and MRI are increasingly accessible in hospitals, this was due to a rapid expansion of the area, the development of computer imaging and now the aid of artificial intelligence can extend the applications and still make the results before now fast and accurate.
This is not a distant reality, hospitals in Brazil in São Paulo and Goiás Brazilians States already have these services, the images are sent to centers that bring together specialists in several areas and the diagnosis is also aided by software with Artificial Intelligence.
The radiologist from a hundred images, where possible internal injuries can be serious, in case of an accident for example, is necessary to make a report that indicates which care and/or surgery are priority, in general, some must be immediate.
With the help of the computer the machine marks potentially serious areas, with arrows or circles indicating them with probability of success up to 90%, but the final diagnosis is of the radiologist.
The problem is in the area of education where, in addition to incomprehensible resistance to the use of this technology, teaching is still done with relative delay in Brazil, in a report made for the Globo News, the USP´s professor Chao Lung Wen said that in more than 300 medical schools of the “There is no disagreement between telemedicine and medicine, there is only one medicine, and medicine has the use of telemedicine to get closer to patients. This is the fundamental point. ”

The supersapiens and the Artificial Intelligence

17 Jun

It is common from a simplistic analysis to demonize the use of new technologies and now with the emergence of Artificial Intelligence, the batteries are turned away, of course there are no ethical objections that are always recommended, but this is true for all areas, including science and religion.
The documentary Supersapiens by director and screenwriter Markus Mooslechner explores the most advanced potential of artificial intelligence, which would link one mind to another, showing that the world is moving towards a collective technological consciousness, the title is an allusion to homo sapiens evolution of the human mind.
In a different perspective Jean Gabriel Ganascia wrote about “The Myth of Singularity”, the idea that a machine can never surpass the human mind, but the film explores a totally new possibility a kind of “networked minds” that from the point of view of a metaphor (the film is not) n In the film, the experts interviewed say that the era we are entering is an era of experimenting with an artificial intelligence connecting minds and their consciousnesses.
In the past, human physical ability was to measure it’s productivity; even though it could be accumulated collectively, now in the information age, intellect and mind have come to fulfill this central role, and immersive technologies profoundly affect our experience.
Today, technologies are totally immersive, deeply affecting the way we experience life, begins with an account of human origin, 300 thousand years ago. The setting is Jebel Irhoud, a cluster of caves 100 kilometers from Marrakesh, Morocco, where some studies indicate that it is the beginning of human life on earth. It is late afternoon, 100,000 years before the emergence of the first modern humans, a group runs into a cave: dirty, shaggy yet human hair.
As this history was discovered, and in the 1960s, a mining group began operations in Jebel Irhoud.
An explosion revealed a cave filled with sediments from the Pleistocene epoch (period between 1.8 million and 126 thousand years ago), there and not now in 2019, our future begins to be drawn, technology is not a more anomaly the very relationship of man with nature and with its origin.
The video illustrates the documentary, not his trailer, but it’s interesting:

 

Browser Safely

26 Mar

Avoid entering personal data, personal photos of children, telephones and numbers of documents in the media or in any services in which an unknown person can access your information, if they ask for personal data by telephone, say that they can not give in.
Data theft starts with some confidential personal information, a password or something. In this way, you prevent against the theft of information and personal data Make sure that the site address belongs to the service, especially the banking service and follow all bank-recommended security standards, rarely ask for documents, and never do it on public computers where passwords and addresses can be recorded.
Do not install software when requested by a site, unless it is exactly the service you requested or the sites of the equipment: Androids, Apple, Sun, Microsoft, etc.
Make purchases on reliable sites, public sales services where anyone can register to sell products are not reliable, if you really have to buy check the feedback from other customers and if there is no feedback is not reliable, false feedbacks are very similar and short , for example, very good, recommend it, worth it or something. The trusted site usually has the figure of a padlock.
Requests for online file storage is a common way to install viruses or harmful files to the connection.
Download only trusted sites or secure platform. Doubtful ads with huge advantages are largely responsible for viruses and loss of connection security, which can involve data theft and file contamination.
Banners and pop-up menus that appear at the bottom of the screen, whether on your computer or smartphone, should be ignored, usually malicious processes.
Last but not least, is the use of emails to send false files and reports about false services, may also send a link, which open may have different meanings than indicated.
Payment request of passwords and personal information by email should be spam or malwares.

To navigate is need, we must live too.

25 Mar

The phrase is not from Fernando Pessoa nor from a Brazilian composer, it was General Pompeu’s phrase to encourage his fearful sailors saying: “Navigare necesse, vivere non est necesse” and later it was also the Italian poet Petrarca in the fourteenth century.
The verses of Fernando Pessoa had the sense of confining his sense of way to creation, and in this sense of life is that we can make a parallel with the current Web browsers.
Besides the Web we have the GPS and numerous navigation instruments for ships, airplanes and spacecraft, which will soon also be tourist trips thanks to Tesla company (post).
Reflections for today must involve fears (there is a book by Martha Nussbaum), the options with many possible paths, the question of security and the transitions to a possible Web that fights the fake news, remembering that these are all problems previous to the Internet (1975) and the Web (1990), since it comes from the industrial revolution.
The issue of life that involves is the Society of Tiredness, put our mind and body under a barrage of stimuli that may seem beneficial but also lead to stress.
The modern man, the pause, the respite, or what Byung-Chull Han calls the “aroma of time”, I thank Portugal who gave me back this possibility for the rhythm of life, social security and especially the Portuguese lyrical soul.
All of this brings life back to life, but to put it in an agitated life without “aroma” is an effort that demands virtues, in the sense of virtue and in the sense of virtuous circles.
But navigating is necessary, almost for everything in life today and living, pausing and breathing as well.

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):

 

Seeing, aiming and vision of World

01 Mar

Seeing, aiming and vision of Citizenship of the world can be limited to the sense of vision only, this means to see, to have vision in the visionary sense means to understand the meanings of what is seen, but also to have a broad view of life, of one’s own culture and that of others, and be capable of going beyond preconceptions, seen also in a positive way, that is, the concepts that we have in a certain field.

“The important thing is not what we look at, but what we see,” recalls American poet, naturalist and philosopher H.D. Thoureau (1817-1867), precursor in the defense of nature.

 In philosophy, the bond to the senses has created a limited world view, where preconceptions can be crystallized to what we feel and accept, and render us incapable of going beyond what we see, surpassing the senses and having a culturally more rich It is the worldview that produces fake news, the need for the Other to have our vision, often limited by the horizons, of how we read the world, often without seeing.

Thus it is written in the Bible Lk. 6:41: “Why do you see the speck that is in your brother’s eye, and you do not perceive the beam that is in your own eye?”, Knowing how to hear and speak is also a complement to the vision, but there is a vision beyond the senses.

The pragmatism of these visions has penetrated and consolidated in modern Western thought, deepened as culture and now we live what I call the monarchy of the senses, a similar view on the level of empathy and social relations, to what Martha Nussbaum calls the Monarchy of the Fear, which I have not read yet, but I make the speculation that before the fear we went through a cultural process of acquisition of values ​​and among them the fear of the different.

It is urgent to broaden the world view, to create the citizen of the world, the return of nationalism may represent for some a vision of peace, but it is a dangerous cultural, ethical and religious closure capable of producing new wars and conflicts even more cruel than the two wars It is possible a common civilization, a global citizenship or how I prefer a united world.

Martha Nussbaum who is little known outside the Anglo-Saxon world gives his answer:

 

 

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:

 

 

 

To leave the twentieth century

26 Feb

When many speak of the education of the twenty-first century, we must know if we leave the twentieth century, thinking, paradigms, the form of education are all frozen in the twentieth century, has little to do with digital age, in his 1981 book, the internet was nascent, Morin already said that the future depended on how to educate for the new century.
He said that with all the “progress” he warned that the danger of war continued to prowl humanity, poverty still persists on a large scale and nature is increasingly shaken by the predatory action of man in this transformation.
He affirmed, contrary to today’s confused thoughts, that it was precisely the means of communication, through which we knew what was happening in various parts of the world, through instantaneous communication, social events on the entire planet.
Of course I warned that there are negative points in this communication, that men know the world only by virtual videos and images (which are not unreal), without being in the world, and therefore the hermeneutic-ontological discourse makes sense, it can create a limited consciousness , but it is also limited those based on ideologies and religions, which use a limited and partial worldview (Weltanschauung).
This being in the world, being absent, is well described by the Polish factionalist Jerzy Kosinski in his modern parable O Vidiota, 1979, on the limit of images, videos and reports.
Edgar Morin clarifies that the news since that time (was 1981), already distorted and hid the real, stating “Information in a totalitarian system is not only a government information; it is, above all, a totalitarian governmental information “, and it is important see any ranking for free journalism.

It is happens not only in the known dictatorships, but in present-day Bulgaria, there are numerous complaints that the press is not free, occupies the 111th rank, where Brazil is at 102, Paraguay at 107 , Bolivia at 110, Colombia at 130, Venezuela at 143, China at 176, a point above Syria, and North Korea at 180.
You can notice in the images that are the darkest regions, the closest to conflicts and wars, therefore, it is not necessary to use the fact that there is subinformation to censor the press, because it is that we can through the denunciation of facts to help society to adjust.
Morin’s book may seem conservative, it has never been, although it has been written for a long time, it can still help us out of the twentieth century and enter into the real problems and situations of the 21st century.
Edgar Morin’s book To Come Out of the Twentieth Century, at first glance, may seem full of reactionary theses. However, I read carefully, it is perceived as a series of serious considerations, based on concrete facts, thus contributing to a truly more progressive and current vision of the contemporary world.
Morin, E. Pour sortir du siècle XX, 1981.
