Commerce grows 24% The e-commerce grew 24% in Brazil in the first
quarter of the year compared to the same period last year, says the study WebShoppers, released yesterday (21/08).
The Brazilians have made over 35 million in the first half, orders via the Internet (20% in value over the previous year) and the price of medical purchases also grew 4, giving the value of R $ 259.49.
The sectors are the record holders “Fashion and Accessories” with 13.7% of the total and appliances with 12.3%, then comes toiletries and cosmetics (12/2%), IT (9%) and books and subscriptions magazines (8.9%).

Particles, the universe and digital signals

In the early twentieth century, the physics
model that is something we might call today the rigid bodies and low-speed, low compared to the speed of light, which became for quantum physics an important reference because it was she who changed our vision of mass and matter, creating a physical micro-particles that revolutionized even the way of thinking and it is important to understand the ‘information’ outside man.
All we can tell, all the model we have today of the whole universe is connected to this physical and she is about to meet a single model: the micro-particles, including photons particles and electro-magnetic waves in a single model, called Standard Model of Physics, the discovery of the Higgs particles or Particle of God in recent experiment done in the particle accelerator at the borders of France to Swizerland it helps this model.
But we must understand that this model corresponds to only what we understand as matter, that this is most stable part of the universe, and physicists call baryonic matter, even though 22% of this it is a “dark matter” (baryonic and non-baryonic) , and there are still a matter totally unknown, but acting on gravitational attraction, which is called dark energy, which permeates the darkness of space.
This information model profoundly influenced the thought of Claude Shannon, a young student who worked on the influence of Norbert Wiener, father of cybernetics, and Vannevar Bush, both his professors at MIT, and which work very close in the late 30.
Later meet up with Alain Turing and then begin to develop this information model “quantized” who wrote in 1948 “The mathematical theory of communication, prefaces by Warren Weaver, and Wherefore sometimes called theory of Shannon-Weaver.
Shannon’s theory was essential to provide treatment “digital signals” analog for it some times is seen as a theory of digital signals and not information.
Privacit is violated in NSA

Are the initial findings of an internal audit, and write in Washington Post, last week, 
the National Security Agency of the United States (NSA) “has violated the rules of privacy and exceeded his authority thousands of times a year since 2008, mainly through unauthorized surveillance targeting American and foreign intelligence in the U.S.. ”
Internal audit, dated May 2012, found 2,776 incidents or violations in which many were made without any “court order” american journal of capital guarantees.
The audit is particularly compromising U.S. government claims that post several surveillance actions were made with the consent of the government.
Firms Google, Facebook and Microsoft now deny the claim “unfettered access” to the U.S. government, but clearly cooperated earlier.
Called to give explanations, representatives of the Internet giants participated in a public hearing in the Senate on Thursday and declared: “There has been no large-scale access”, defended the company Bruno Magrani, manager of government relations Facebook , saying they were only 0.00002% of the requested information to Facebook, were requested directly by the U.S. government.
The government can deny, but vigilance happens, especially in Brazil, not because we are considered “special” to the U.S., but because we are a big hub in the global network.
Brazilian law PEC 479: broadband is a priority
13
Aug
The PEC 479 amends Article 5 of the Brazilian Constitution, to provide broadband 
to the population should be a priority of the State, since “in contemporary society, universal access to information is consolidated as a key element for economic development and social nations”, according to its author Mr Sebastião Bala Rocha (PDT-AP-Brasil).
The reasoning is simple: to provide broadband to the population should be a priority of the State, since “in contemporary society, universal access to information is consolidated as a key element for economic and social development of nations” as stated by the deputy I proposed.
The PEC was proposed in 2010 and approved by the Constitutional Commission of Justice of the chamber in May 2011 and sees the social changes taking place, since “the internet, in particular, plays a crucial role in the construction of this new reality.”
The meeting is scheduled for tomorrow, 14/8/2013, 4 on the floor of the House of Representatives, and the SGP, the rapporteur Mrs Gorete Pereira (PR-EC), is approved, will be voted in two readings by the House still this month.
Common screen now is touch too

Aug
With the arrival of Windows 8 and html5 facilities beyond the photos,
videos and sounds, touch interactivity also here to stay.
But what to do with the common screens that still use a pen came to turn them into touch screens too.
The device Apen Touch 8, E Fun, is secured with a small device with magnets in the corners of the screen and connected via USB to the computer, which has a pen at the other end “optics”.
So the movement of the pen on the screen makes iterative identical to a touch screen, no need for any software or any device more.
Actually the pen is not optical, but ultrasound, as it uses the technology of motion capture by infrared rays, the play on the monitor attached, it captures the movements of the pen and creating the feeling that the commands are triggered by touch on the screen.
The device is sold in the U.S. since the beginning of the year at a price of R $ 160 (U$ 89), and is present at CES 2013 as one of the news.
More about security and privacity
05
Aug
The issue is recurrent, since the internet (the middle physical´s initial) and Web (the popular application that started in the 90´s) 
were expanding it became more frequent, and is now a priority issue on the destination Web.
Now with former hacker official U.S. government announced the spying on American citizens and on other countries, it has become more important on the Web.
But security and privacy should not be treated as a single topic, although it is impossible to separate one from the other, in the privacy the individual knows what information people who allow them to be collected and published, and knows how to treat this information, but this should know how control this privacy.
According to an article from AT & T this information may be collected and would be correct to look at them.
Here comes the aspect of safety, only security should include factors that include physical security and human, ie “only security information” where factors including business, physical integrity of persons and / or disaster recovery may be included these factors, there is an international standard for this to ISO 17799.
Safeguarding customer information, this means that any site or social tool (not just Facebook, but mostly he) must protect the security, confidentiality and integrity of information from a “client”.
Management and Identity and Access Management (IAM, Identity and Access Management walks), which is undoubtedly the most critical factor of privacy, but not always given due attention because of the difficulty and cost of implementation.
Users are often employees, customers, suppliers, or a simple computational access to the environment and engage in corporate services without knowing what they do. The environments themselves are becoming increasingly complex, make offers “knowing” the taste of the client, exploring their consumption capacity and interconnecting applications.
The clouds are a particular danger for this invasion of privacy, SOA (Service oriented Architecture), since his own role as a service is to use the functions or services and not just traditional applications, and this causes the control access more difficult.
Security, coding, testing and application management is another risk factor, as application attacks have a great success due to the ease of vulnerabilities in most program code, programmers are famous for, the risks of programs written in Java, but weaknesses imply how many programs and services have been implemented.
Such findings may be accidental, such systems have recently been discovered in Apple’s iOS and Androids, showing that this is not the privilege of any company, but they are important as they are detected and remedied when companies advise their customers as part of a recall, but this is not done.
The safety aspects are not few, but should also include: protection and data encryption, protection against malware (viruses), managing and monitoring operational risk.
