A team of researchers from the University of Southamptom , UK , created a crystal capable of storing digital
information in five dimensions , beyond the three conventional space , plus two extras using nanostructures ( structures at the level of the atom in the order of 10-9 meter) .
These devices can reach the capacity of 360TB of data stored , equivalent to one million times larger than a CD , for example , 360 GB , assuming it has a display device and projection, one childhood memory of Superman, would practically possible now .
Because of the similarity with the film , the device is already called “crystal memory of Superman ” because the crystals resembles memory movie Superman .
According to Professor project supervisor , Pete Kazansky : it is ” exciting to think that was created the first ‘ document ‘ able to survive the human race ” as this ” this technology can store the latest evidence of civilization : what has been learned will not be forgotten ” , and under normal conditions will keep the information for 1 million years .
The paper ‘5D Data Storage by Ultrafast Laser Nanostructuring in Glass’ was presented in Conference on Lasers and Electro-Optics (CLEO’13) in San Jose.

Being a two-dimensional code, QR (Quick Response) can store more information than exponentially
one -dimensional bar code (white and black is 0 is 1) , storing content information complex , adjacent to the URL , for example, directs this blog .
The code was generated from the Google url shortener , then selecting ” details” .
Using some gadget camera or scanner , the code is converted into text, which can then be interpreted as using the text ( interactive) , with a URI address , phone number , located georeferenced , an email, a contact or SMS .
The QR Code was first used in the production of vehicles, but is now used both in inventory management and inventory control in industry and commerce.
From 2003 applications were developed to facilitate users to enter data in mobile phone using the phone’s camera .
QR codes are also common in magazines and advertisements , to record addresses and URLs , as well as detailed personal information.

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

Oct
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.
