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.

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:


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.


CES 2019 started

09 Jan

The world electronics fair CES (Consumer Electronics Show) began yesterday in Las Vegas and goes until Friday (11/01), what can be seen there?
This year the strongest news seems to be Smart home, smart home, many news, with the advancement of artificial intelligence, the house that already has electronic vacuum cleaner, electronic control of lights and household appliances, will start to talk to you.
Smart TV is already there, and unlike imprisonment, a lot of people have stopped watching conventional TV programs and channels, use them for movies, series (replacing old soap operas) and uses to stream Youtube videos and family filming, this is already in change.
Gradually from the fun this goes to areas of health and interaction, nothing to do with the movie BlackMirrow (see the post), wearable fitness devices and medical equipment for health.
One of the companies present is Neutrogena, which works with skin-related products, covers scanning a 3D human face and creating custom masks for each face, pressure controls, glucose and others are already available in the markets.
But the wiring and gadgets for each is going to change radically, cable-free TV and WiFi-enabled connections are now available, a new type of plug already dubbed a “transformer plug” and the cameras just to watch now can make projections throughout home, including TVs and Web devices for intelligent interaction.
Robots who clean the house and bring things from the refrigerator to you, machines that fold clothes, smart sleeping masks, self-cleaning toilets, were already present last year.


The first quantum computer hub

30 May

The North Carolina State Unit was chosen by IBM to have the first Quantum Computing Hub (Q Hub that became part of IBM’s Network Q), as well as the first networks linking some universities.
On December 5, 1969, ARPANET joined the Research Agency of the US Department of Defense, the University of California, Los Angeles (UCLA), the Stanford Research Institute (SRI) at Menlo Park, the University of California, Santa Barbara (UCSB) and the University of Utah (photo).
Students, faculty and researchers will be able to access IBM’s 20-bit supercomputer to solve classic computing problems that would take a long time to process, now they will be done in a few minutes depending on the problem.
Bob Sutor of IBM Research said “we can not create a computer with 10% of the Earth’s atoms, but even so, with the quantum computer we can represent exactly this information”, according to a post on Techinician Online.
IBM’s plan is more audacious, with Fortune 500 companies and universities working to solve larger problems more quickly through the Q Network, while NC State will be collaborating with local organizations to solve complex equations.
NC State faculty are developing both undergraduate and graduate courses to use quantum computing to build their knowledge in anticipation of the hub’s operational debut this fall (in September).


MacronLeaks and elections in France

08 May

Even with Macron’s victory in the second round of the French elections,MacronLeaks and the defeat of ultra-right Marine Le Pen, did not let to be noticed a case that was the most serious Hacker attack ever known to try to influence an an election.

Post-truth times after the urgency on Saturday morning of the National Committee for Control of the Presidential Campaign in France that begged the press not to disclose the information on Macron, the fact in the digital universe that there is no control as to how Control of false information, the only possibility is to publicly deny it.

Following an emergency meeting this morning (6) to examine the case, the committee extended the notice to all the population and users of social networks warning that the disclosure of these documents (the “MacronLeaks”, as it has been called in France) May involve “criminalliability” of its perpetrators.

Still no effort of despair, because people who do this kind of action does not have an ethical conscience on the fact, the body asked that “the actors present in Internet sites and social networks, first means, but also all Citizens, to have responsibility and not to transmit such content, in order not to alter the transparency of the election, not to break the law and not to expose itself to a criminal offense. “

In addition, he warned that they were “mixed with false information”, so retransmission of these facts is “susceptible to receive a criminal qualification of many types and to carry the responsibility of its authors.”

En Marche, founded by Macron after breaking with the left-wing Holland government, reported on Friday night that it was the victim of a “mass and coordinated hacking attack” that led to the leak “in the internal social information networks Of diverse natures “, we are waiting for the final result of the elections for analysis.

But an irreversible fact is that some form of control over false information in election campaigns will be necessary from now on because the network effect can make them uncontrollable facts of lying versions about the candidates reversing opinion and forces in a campaign.

European newspapers speak of “relief”, “thank you to France” and the strengthening of the European Union, but “hidden” forces may favor authoritarian and conservative positions.



Chip revolutionizes IoT

24 Feb

A company almost bankrupt decides to invest in the development of a chip for the ESP8266Internet of Things (IoT) not only saves the company itself but promises to revolutionize the market.

The chip is the ESP8266, from Espressif company, the price $ 5 (5 collars), less than a coin and integrated in several solutions, for example, communication with the serial interface of most computer models, the UART Universal asynchronous transmission), this means transmission with which devices with TCP Internet interface.

It is a System-On-Chip with built-in Wi-Fi, It has GPIO connectors, I2C buses, SPI, UART, ADC input, PWM output and Internal temperature sensor, CPU operating at 80MHz, capable of operating at 160MHz, 32-bit RISC architecture, 32KBytes of RAM for instructions, 96KB of RAM for data, 64KB of ROM for booting, SP SP memory and Winbond W25Q40BVNIG of 512KBytes .

To program them, the company has a repository in GitHub, where it provides code samples for RTOS firmware and AT commands, and its SDK, for example, in addition there is an ESP8266 developer forum, maintained by Espressif, where it is possible Find a wide range of materials.

Will we have new developers of garages around the world?


Barber shops, cafes and nets

14 Feb

According to Peter Burke, the locuCafePariss of religious and political discussions in 1620 was the barbershops, quotes the Italian writer Ludovico Zuccolo, who evoked them full of ordinary people discussing the religious problems and the attitudes of the rulers.
The first great wave of reading was to interpret the Bible, the same that Galileo had claimed and which is still ignored today, the same Ludovico said that as the number of illiterates fell, they were common in the sixteenth century in Italy, for example, shoemakers , Dyers, masons, and housewives, claim the right to interpret the sacred scriptures.
In the 1620s religious concerns were compounded by political concerns. Ludovico Zuccolo, an Italian writer, evoked the image of the barber shops full of ordinary people discussing the measures of the rulers.
Anyone who thinks that there is an excess of information today, as soon as the books began to be printed at more reasonable prices, one already complained about the number of existing books and how one would read them in a single life, in 1975 for example, 1745 The Vatican library, housed only 2,500 volumes, in the seventeenth century the Bodleian Library of Oxford had 8,700 titles, and the imperial library of Vienna, 10,000.
From the barbershops to the cafés, Café de La Paix is ​​the scene of many novels, paintings and poems, Guy de Maupassant and Emile Zola frequented it, the proximity to the Opera Gamier (next door) made it a kind of Museum, In 1975 it was considered a historical site by the French government.
Would cybercafes be your descendants? They lived with libraries and other places of dialogue and culture, they were important in the “Arab Spring,” especially in Libya and Egypt, there were violence events with heroes who posted denunciations in these cybercafes.
Both the uprising in Egypt and Libya were recorded in numerous social media, a good example is the video with 2,000 deaths (video of OneDayOnEarth), reveal the taste of the dictators for the worship of the person and vertical media.
Long before the outbreak of the war in Syria, looking at the comments on the networks, we knew that there was a powder keg (see our post 2012), and also a blogger Tal al-Molouhi, arrested in 2009, was one of the fuses for the uprising.
The governments and owners of vertical media do not accept the influence of the networks, because it is their bankruptcy, but now even the authoritarian Trump does not give ball to them, makes its own media, of course it does not go unanswered, in social media media Is losing ugly




Latin America regulate IoT or not

09 Feb

IoT (internet of Things) is there, cars, clocks, medical equipment and other devices IoTneware already on the market, this should grow to the full connection between things that communicate.

According to data from the 5G Americas report “Internet de las Cosas en América Latina” (made in the Spanish language), the concern over excessive regulation may impede the business model, while in Brazil, experts point to the contrary: the need for urgent regulation, Who is right?

Both of them, but it takes a matter of common sense, in general in Brazil it regulates to the shape of the pins of the outlet (a joke, but it is true), while abroad the concern is with security and standardization for everyone to adopt similar measures .
The main concern should go to the sense that it takes a lot of attention not to prevent the advancement of a new business model while ensuring more security, but without panic and exaggeration, nothing is totally safe, but of course it is necessary to adopt measures, more Equipment will mean less security.

According to the 5G Americas report, through one of its director José Otero: “The risk of excessive or ill-conceived regulation could delay the enormous growth opportunities in the Internet of Things. For this reason, it is necessary that the entire ecosystem of actors dialogue and collaborate with regulators on this important technological advance. “

According to a Machina Research consultant, Andy Castonguay, if the fragmentation and complexity of the IoT system and its many technological approaches make the deployment a challenge, it will be somewhat dangerous if regulators are prohibitive in their mandates or if they favor Technologies.

One of the main considerations regarding public policies in the sector should be made considering the sovereignty and privacy of information and for security


(Português) Pontos da IoT para 2017

27 Oct

IoT points in 2017 The company’s technological forecasts Gartner analyzesiot2017 because the IoT (Internet of Things) has not yet kicked off, and points out some points that can make this internet happen in 2017:

IoT security

The IoT has introduced a range of new security risks and challenges for the devices, their platforms and operating systems, communications and even systems which may or must be connected. Safety is something complicated by the fact that “things” have individual processors and their own systems, such as batteries, operating systems and devices that heat.

IoT Analytics

Analyze performance and functions in “things” is different to do on computers or smartphones because the business model is modified to the extent that will analyze information collected by things not by customer in ultimately are people, new tools and algorithms analysis are under development, but it is believed to be stable around the year 2021 should go to developing as needed.

IoT management

“Things” delay duration are not trivial, require management and monitoring.

This includes monitoring devices, software and firmware updates, diagnostics, analysis and reporting of accidents, which may cause problems in scale to the management task.

We highlight these three essentials, but now will have others that Gartner notes: Processors management in wider areas with internet connection, processes and low-power processors, platforms and operating systems for the IoT, and finally Standards and Ecosystems for IoT.

More detailed analysis is in the Gartner report ““Top 10 IoT Technologies for 2017 and 2018.”
