Web 3.0: coining words and give them meaning
22

Web is not just that I’m talking about, but also and especially of people, make sense,
especially human, the things around us requires thought and act more and more just on impulse .
On this blog I spoke earlier of the word selfie, but I have already spoken of Instagram and ordinary people and everyday landscapes that go through our day to day “photographic”, so too is the case of Web 3.0, or fashion trend?
John Markoff was who coined the word Web 3.0 in the New York Times , Web 2.0 has already happened , it created hundreds or thousands of applications ( Apps of considering the cell ) and included the common user as producer of information , now photos , posts , comments and ” hashtags ” are there calling our attention , but these people should ALWAYS be seen and heard , they were not.
The problem of our day to day , and also that the Web is a reflection and not an idealization of the day – to-day as some think , is that much that ” lacks ” direction , and found thousands of photos to look at , words and videos means that we need them or them offering new significance .
John Markoff suggested simple questions such as: “I’m looking for a warm place to vacation and I have a budget of $3,000. Oh, and I have an 11 year-old child”, but actually thought of business , as own title and article suggest, by example Spivak company, Radar Networks, working on the holding of the content of social computing sites , which allow users to collaborate in gathering and adding their thoughts to a large amount of contents, travel movies.
But Web 3.0 now seems to be finding its way , projects like DBpedia and VIAF ( Virtual International authorit File) are indicating a more social than technical , although it may contribute to this, there is still a way in this ” construction ” .

The rise of smartphone adoption has been rapid device market millstone stable in five years reached 1
million, now two years has reached 2 million, report of Ericson says.
.
The growth will continue as inexpensive models become more available in emerging markets , this market is that Motorola / Google is eyeing the Moto G, already launched in Brazil and another on price and user who did not migrate .
The data networks of the world also come to expand to keep up the demand for data that is already big plus is expanding, the problem is the connection.
.
But current analysis , such as the EcommerceTimes says 90 % of the world population will be covered by WCDMA / HSPA in 2019 , i.e. WiFi network , and even more , 65 percent will be covered by 4G/LTE networks , will the Brazil too?
.
LTE connections in North America will surpass all other parts of the world , according to a forecast from the site , will reach 85 % coverage by 2019 .

The Institute Date Favela conducted a survey in 63 communities in the last week of September,
the metropolitan area of São Paulo , Rio de Janeiro , Minas Gerais, Pará , Ceará , Pernambuco , Bahia , Paraná , Rio Grande do Sul and the Federal District , and found that 52 % of residents have access to the network and among young people 16-29 years old, 87 % are those who are connected .
According to Renato Meirelles, president and member of the Popular Data and Data Favela, along with Celso Athayde , president of the Central Unica das Favelas (Cufa) : ” If the TV was before the window of the world to the residents , the internet appeared as a showcase : it the resident , especially the young , can show up and show their reality. ”
As for households , the data is that 50 % already have internet connection , being more common broadband, followed by mobile 3G modem .
In the analysis of Raphael Claudia de Oliveira , state coordinator of Cufa – SP : ” It is a cultural issue that goes beyond the technology itself. ‘s Global : the barrier between the favela and asphalt broke , this cultural exchange there ,” he said .
The data social networks are more impressive still , according to the institute , 85 % of those who have internet already on Facebook.
Internet security company and world

The reasons confess to spying on the network leaked by Edward Snowden , a former official of the
U.S. National Security Agency ( NSA , its acronym in English ) , and inconfessas which is the desire of the state to control its citizens , opened debates about national security and privacy and taking global proportions .
However , for now , there are more proposals were rejected than statements about what they want , the reason is the complexity of interests involved in a debate , and motivators among countries is Brazil .
In the United States , one of the promoters is study center Wilson Center in Washington , more present , however the view of experts that political issues , but at least brought fundamental questions on the technical and ethical .
What they desire is to harness the desire of governments to citizens patrol , not always terrorists , but not respect fundamental freedoms and privacy rights in Western societies , it would be possible ?
The confrontational discourse of ” sovereignty ” is an ideological appeal to national issues , the demonstrations in France , a country with a nationalist color highlights on the expulsion of aliens , seems to strike a chord among the young .
Attempting to national states , creating networks ” own ” , called by experts ” Balkanization ” is nothing more than repeat the nationalist discourse and fail to see the world as it already is , ie , a society – world as Edgar Morin calls .
So , if we have a solution that it is global , without taking away freedom of world relations , networking, of all humanity , respecting the privacy of every internet user .
More confused minds the Web

In a report in brazilian magazine Epoca, also the book of Mark Bauerlein to Nicholas Carr, author 
of The dumbest generation there is a pessimistic analysis in that it anticipates a new Dark Age , when individuals who are now children and adolescents reach maturity .
In analyzing this author in Epoca magazine , ” once youthful minds restless and full of knowledge , what we see in schools is an anti -intellectual culture and consumerism ” , attributed to Bauerlein , a professor at Emory University in Georgia , which oversees studies about American cultural life .
His study on the influence of digital media was done with 81,000 American high school students and second it was found that 90 % ” read or study ” less than five hours per week , and spend many hours watching TV , surfing the internet or playing video games , an average of 6 hours per week , and then takes to conclusions , saying ” do not know practically nothing of history” , etc. .
I do not know if the data of the 60 youth would be different , just did not have internet and had the war in Vietnam and Brazil , were times of military rule , and even speak the word dictatorship was forbidden , educational systems were repressive and little inventive , luckily I entered the first class of computing and had some regular teachers , who read and reported on the country’s history , but was also minority.
We read romance, but it was something with sugar water , but we really wanted was a color TV to watch the Brazil game , can not remember if he sang ” this is a country that will put forward will ” actually liked math and I only understand policy when I entered the university, but I am the fruit of the hippie generation and the ” hairy ” .
The lessons were always silly stories , had to memorize dates and know what were the ” national heroes ” finally no critical analysis of reality , the university was reading because it was an alternative set of left and needed to have arguments against the ” dictatorship ” today I thank the “rebels ” of my youth , without them I would also be a ” dumbest generation” .
How long we were in front of the TV culture engulfing canned ? what they say about Arab or Muslim culture in our newspapers ? someone knows something of African culture ? Whose dumpest generation ?
The problems that befell this generation has no connection to the lost generation (1914 – 1924) , the baby boomers generation ( 46-64 ) and hippie generation ( 64-84 ) ? is it only now are ” dumbest ” ?
European Parliament for digital privacy

The committee of the European Parliament for digital privacy, Libe, approved on Monday a new draft regulations for the 
privacy issue , the document follows the great initiative of the European Commission for more data security .
Across Europe , digital privacy advocates agree that there are on the right track , it is urgent to tighten legislation to protect internet users .
One of the rules is to make more visible what appears almost imperceptible on their data , the clauses that are usually hidden in the general conditions, and are presented as the default setting when you register on some website .
Companies with headquarters outside the EU although they can circumvent the existing safety data , they should seek those with laws more flexible , which made Ireland and the United Kingdom ‘s most popular destinations , but the situation should change with the adoption of equal rules for the entire block.
One of the proposed rules Libe is that users can delete their personal network more easily , allowing clear without being previously stored .
Users also have the right to know which companies or government agencies also your data may be transferred , this means privacy.
German Institute development Wifi 100 GB

According to Gizmodo , the German Fraunhofer Institute for Applied Solid State Physics ( IAF ) 
and the Karlsruhe Institute of Technology ( KIT ) have developed the world’s fastest Wifi , which exceeds 100 times the Google Fiber internet offering 1 Gbps ( gigabit 1 per second) but using fiber cables great for this.
According to the Institute it Wifi can transfer data at a rate of 100 GB per second without fiber optics, it is possible to transfer the entire contents of a Blu – ray , for example , in just two seconds , indicating a longer application.
Those responsible for the project also asserted that the speed of data transfer can be increased with the use of special optical and electrical techniques ( fiber optics and special cables ) , or with the use of multiple antennas for transmission and reception .
Gizmodo already has announced a super antenna using graphene .
The way things are going telephone signals in Brazil maybe this would be a solution
Berners – Lee supports DRM to html5

One of the strengths of Web formats is also becoming a standard for textual formats , the html5 , 
however to be a free format could be difficult to control the DRM ( Rights of copies ), but Tim Berners – Lee said that this can be controlled .
The news came out in Zdnet thus proposed extensions to encrypted media ( EME , Encrypted Media Extensions ) will be placed in the next HTML extensions due to criticism from various groups and activists on digital rights .
Earlier this year , 27 organizations , including the Electronic Frontier Foundation and the Free Software Foundation , considered the proposed specification above as “disastrous ” by claiming they would change HTML to encourage the use of DRM .
According to the CEO of the group : ” We do not walk to standardize DRM systems owners , but on the other hand we do not want it to be deleted from the Web platform .”
EME have a hook for audio , video and other content within the HTML , providing support for digital rights management within the HTML which would prevent unauthorized copies , for example, movie studios and musicians , and could even automatically remove Web content
The EME specification describes an application programming interface ( API ) that interact with a DRM-protected file as the media used , and a first version of an editor was published by the working group to draft a HTML editor , but not yet approved by the W3C consortium .
To facilitate the group is : ” a commitment to a set of open APIs that provide a standard framework to bring this content via plug -in , but does not wish to standardize the plug -in ” , so that the structure remains open to developers .
The idea is good because it gives the option to open a Web preserve the copyright, in what is most basic to the web is the new standard html5 .
Response to spy might be wrong

The idea of forcing Internet companies to store user data within Brasil is mistaken as to the concerns
of cyber security in Brazil, as well as increase costs and undermine future investments, may cause further uncertainty to the data and the privacy of individuals, as it being here can also be manipulated.
In the case of investments, it is important to recognize that there is an emerging market related to Google, Facebook and Twitter, say analysts and industry executives.
The teacher Ronaldo Lemos (State University of Rio de Janeiro-UERJ), which helped create the laws of internet in the country, said “may end up having the opposite effect than intended, and scare off companies wanting to do business in Brazil,” as the news portal Terra.
Already the rapporteur of the law of the Internet in Brazil, the Marco Civil, Mr PT Alessandro Molon (RJ), said the number of affected companies could be counted “on both hands.”
The modern networking technology, cloud computing depend on both in terms of technology as in investment values of international participation, and confinement in the country will result in costs and shrink the investment markets international investments to be made in the country.
But more serious is that besides not allow control data, may also be used politically depending on whose hands fall control of our “network”.
The markets today are international, and border closures could mean delay.
There are ways to control encrypting messages, and controlling flows regardless of where the data are, in fact this is the internet.
