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.

AI will help fight fires

21 Feb

The famous US Department of Defense (DoD), which is also on the internet, has launched a program to use artificial intelligence (AI) for drone data analysis to improve how forest attacks are fought, the news is on Wall Street Journal this week.
The project uses algorithms that evaluate photos and videos, being themselves the ways of forest fuels and improving efforts to contain them, data on resources in helicopters, but also using drones and other cyberspace data on the administrative functions of as part of efforts to improve its efficiency.
A program to monitor and attack forests in California and other parts of the country is one of two pilot projects the Pentagon released on Tuesday.
The program, solved the Pentagon, oriented strategies to establish new innovation strategy of artificial govern, that must to work performance with the academy and the industry for better to advanced information management and data application.
The reason for the fires is clear, also in the Portuguese rhodians, which are a combination of vulnerabilities in the work plans of children can issue fires, such as the serious happened at Camp Fire in 2018 in California, see CNBC vídeo:


Fake news with few days

12 Feb

False, malicious or biased news are old, we have already mentioned the allegations made by Karl Kraus, also news that actress Rita Hayworth (the stage name of Margarita Carmen Cansino, famous in the 50´s and 60´s), who would have lived another two years , or the misleading advertisement that Nike would be giving shirts of the Brazilian national team.
Now there is software developed by the research company Fraunhoffer-Gesellschaft, in Germany that has developed a system that automatically analyzes post of social media and filters false news and misinformation, we can predict a promising future.
It is worth mentioning that this was thanks to the new technologies, the tool does a machine learning that filters the news and through learning (in the sense of algorithms per machine) analyzes contents and metadata, verifying user interaction and optimizes results in real time.
The tool also checks the amount of data (viralization processes), with sending data graphs, frequency and follower networks.
Ulrich Schade, according to the Fraunhofer website, said: “Our software can be customized and trained to meet the needs of any customer. Our software can be customized and trained to meet the needs of any customer. For public agencies, it can be a useful early warning system.”
Metadata are used as markers, thus allowing fake postmarking, that is, it plays a crucial role in differentiating between authentic sources of information and false news.
So if a site with a certain frequency of posts is made, how often and how a tweet is scheduled and at what time? The time of a post can be very revealing, as well as the frequency of the tweet and the followers.
It should also reveal the country and the time zone of the originator of the news for its correct identification and location, therefore the hours are essential.
A high frequency of sending suggests bots, which increases the probability of a false news, can be easily detected and can signal a fake.
Social bots generally send their links to a large number of users, and this is an example of how to spread the uncertainty among the public, so never give in.
Connections and account followers can also be fertile ground for analysts, although well-intentioned people use it, the chance to be a fake is great, and now a tool can detect it, fake days are counted.


Thinking and linearity

04 Feb

The linearity of thought is so impregnated in contemporary culture that even expressions such as “a straight man,” “righteousness,” or equivalents become synonymous with fairness, good, and social harmony.
This is more connected to mathematical reasoning than to empirical reasoning. It is no coincidence that the examples formulated by the rationalists of the sixteenth and seventeenth centuries used the triangles as examples of the idea of universals, and even in this case separated subjects from objects, not by chance either Descartes (1596 1650) and Leibniz (1646-1716), were also mathematicians.
For rationalism both ethical and aesthetic ideas, as well as Justice, Virtue and Beauty, must also be objects of the World of Ideas, so a whole construction was made according to this way of thinking that is now in crisis, because the separation produced a Being that is strange to Thing, to the Ens (thins that being), making a pun: the problem of the Being of the Thing (in portuguese make a word sick: Do-ente).
Fundamentalists, having an intuitive basis for contemporary thinking, argue that Being is “spirit”, which has little or nothing to do with spirituality or religion, on the other hand the materialists argue that we are pure beings, to be of nature and thus substance.
The empiricist prior to Kant, the Scottish philosopher David Hume (1711 1776), while admitting that all ideas derive from experience, denied the method with the use of induction: “What is the basis of all conclusions from experience?” (Hume, 1985: 37), or how is the passage from observational statements to universal statements justifiable?
Hegel intended to take this to the spiritual plane in still idealistic Spirit Phenomenology. Although idealism / empiricism could appear to be a complete epistemological system, in 1829 Lobachevsky developed non-Euclidean geometries, then came the hard surfaces (photo) of Rieman (1826-1866) whose generalization takes the dimensions of Haussdorf (1868-1942) and to fractals, who also wrote about philosophy as “Paul Mongré”.
But it is not only the complexity of physics and mathematics, the ontological resumption of being goes beyond logicism and empiricism, it is the ontological resumption.

What is diffusion of innovation

20 Nov

An innovation to reach the market, if it does not fall into disuse that is a possibility, goes through a process called “adoption curve”.
Everett Rogers, is a recognized in this area of communication studies, professor of department and journalism of the University of New Mexico, his book Diffusion of Innovations, already 5ª. is one of the most cited books in the area, the first is from 1962, and the author died in 2004.
Their main argument is that innovation is communicated over time among participants in a social system, and the origin of their theory spans several disciplines and although it has never used the term, it can be safely stated that it is transdisciplinary.
Rogers proposes that four main elements influence the dissemination of a new idea: innovation itself, communication channels, time and a social system. This process depends heavily on human capital. Innovation must be widely adopted to sustain itself. Within the rate of adoption, there is a point at which an innovation reaches critical mass. That can also be understood as the curve of adoption
The theory characterizes 5 advantages for adopting a technology: 1) the advantage of improving an innovation over a previous generation competitor of a product, 2) from a point, a team must improve the advantage relative to its competitor in potential for there to be no return to the previous product, 3) the new product must be compatible with the previous one, not only when installing and operating, but especially with regard to the potential consumer’s lifestyle, 4) relevancy at the time of launch which means a deep understanding of the conditions that innovation finds in the moment it is launched, and 5) what is the complexity or simplicity of using innovation when it is launched, complex innovations can reach a small audience only.
An innovation to reach the market, if not fall into disuse, is a possibility, goes through a process With its successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach saturation level.
