200 years of George Boole

Nov
Born November 2, 1815, Algebra which created was instrumental in
the birth of digital logic (0 and 1, or F=false and V=True), and later at MIT, Vannevar Bush suggested to Claude Shannon who was to become one of the foundations of modern digital computing .
The development of Boole became one of the important mathematical schools, which would influence the philosopher Bertrand Russerl, who wrote; “Pure mathematics was discovered by Boole in his work ‘Laws of Thought’ ‘which was published in 1850.
Although this is a mistake, because the thought does not move for binary laws, Yes and No, as there is perhaps the power and an endless variety of possibilities, Boole later did important work called invariant (or calculus of variations) , which influenced the Theory of Relativity of Albert Einstein.
In 1838, he published a pamphlet called The Mathematical Analysis of Logic, which influenced De Morgan who made a number of simplifications to make the laws of Algebra Boole more simple and easy to be “adopted” in mechanical, electromechanical processes (relays that have emerged more afternoon) and all digital devices that have emerged from these “laws”.
Although it has already died with great respect, it was Whitehead and Russell work Principia Mathematica (1910-1913) who convinced mathematicians that symbolic logic should receive your serious attention.
Facebook goes down

An instability that occurred in much of Facebook
worldwide on 28/09 in Brazil near the time of 16:05 p.m. Brazil (14:05 p.m. USA), paralyzed the services leaving the API (the service login interface) down.
The Facebook said: “A broad question with Facebook is leaving the API Facebook unavailable search engine We are working with our central infrastructure teams to identify the issue and we will update them when we have. More information”, said the Benjamin Golub Facebook enginner.
The fall of the service had already taken place last week, but was shorter, now users reported longer instability for both accessing the social network via computers as by the application, the 17h17 pm (15h15 USA) was still unstable service
Novidades IFA

Depois da da CES e do MWC, a IFA 2015 de Berlim é a maior feira de tecnologia
do mundo, ela se encerra hoje (09/10) e já podemos conferir os destaques.
Na feira a Samsung anunciou o Gear S1, um relógio inteligente, com formato parecido aos antigos já que é redondo e possui botões com as funções de Home e voltar, o comum e o classic, com pulseiras cinza escuro ou prata com pulseira branca.
Para competir com ele, parecendo ainda mais um relógio comum, mas com design e nas funções aprimoradas o Android Wear aparece como um smartwatch que pode competir no mercado dos chamados dispositivos vestíveis, a Asus lançou o ZenWatch 2 que não muda muito o modelo anterior.
A Sony lançou no evento Sony Xperia Z5, já disponível em algumas regiões do globo a partir de 699 euros (aproximadamente R$ 2807,00), mas ainda não sabemos quando ele pode chegar ao Brasil. A Acer lançou o Predator 6, um phablet com especificações ideiais para rodar games pesados, quatro alto-falante e um design um tanto polêmico.
A LG levou para o IFA não um smartphone, mas um acessório lançou um novo teclado externo tanto para tables como smartphones, feito com plástico ABS e policarbonato permite flexibilidade e resistência a choques.
Novo papel digital Sony

Lançado a um ano, o papel Digital Sony (Digital paper Sony) já está sofrendo 
redução de custos e melhorando tamanho e formatos dos seus novos “papéis digitais”.
O papel digital vem sofrendo um crescimento robusto nas vendas, segundo o blog do editor Michael Kozlowski do Good E Reader, e o preço do DPT-S1 já caiu de U$ 999 para $ 799, e a intenção original que era se estabelecer numa faixa de leitores específicos, que querem ler o PDF e não consumidor da Amazon e da Kobo, por exemplo.
O Livro Digital Sony está experimentando vendas robustas para profissionais da indústria que exigem uma tela de e-paper grande. A fim de ampliar seu alcance e escopo, a Sony acaba de anunciar uma redução de preço no DPT-S1 a partir de $ 999 para $ 799.
O preço caiu logo de início com o crescimento das vendas, lançado a U$ 1200 para o ensino superior, advogados e também entretenimento, logo começou um serviço de vendas online e o preço começou a despencar.
Com o preço agora também consumidores de nível médio, o material de plástico flexível baseado em OLED (que é a tela “orgânica” flexivel), apesar de seu tamanho de 13,3 polegadas (quase um formato A4), ele pesa menos que um Kindle DX de 9″ ou 7”. O DPT-S1 tem tela de 13,3 polegadas, resolução de 1200×1600 pixels, armazenamento de 4 GB, com externo de micro SD até 74 GB, conectividade b/g/n e bateria Li-ion comduração de até 3 semanas e peso de 376 g.
The future of the Internet is social

Fear and ignorance of the technology produces an technophobia that prevents
them from seeing the great strides that the internet and other technologies provide, a recent study published in the IMDEA site shows that the future of the Internet is social.
The work was done by IMDEA Networks Institute who announced the successful completion of its Content Distribution Research projects done by the European Advanced Institute of Social Information (eCOUSIN – enhanced Content Distribution with Social Information).
The findings of the project gather data from the purpose of the research, the agreement made between employees of the European Commission that it had as main objective to create an innovative network architecture that improve the efficiencies of online social networks, as well as provide a quality experience users.
The idea of the project was to explore the growing popularity of social content online and their interdependencies, focusing on data collection and analysis, the scalability of the network infrastructure, connecting features related to the contents, and guided by social information through algorithms projects.
Nine partners from six countries and four universities participated in the project, including IMDEA based in Madrid, which contributed passive and light measurement tools, performance models, and predictors of mobile networks, as well as algorithms for resource allocation optimization.
Crowdsourcing of the smartphones

Is it possible to compete with the big brands and create thousands of 
small business smartphones in the world? it seems so, is proposing the Shenzhen Zuoer Technology, which promises to help customers who want to build their brands around the world.
The customer chooses from a list of options like a menu from a pizzeria, and may enter the cellular industry for only $ 1,000, even without prior experience, the ultimate goal is to create a brand of smartphones with standard components to a price can reach $ per unit, incredible but true.
Accept applications by a minimum order of 50 units, Zuoer ride your own external plastic housing with LCD screens, circuit boards and batteries from other manufacturers. So any customer, anywhere in the world can compete with Samsung in the international mobile market of $ 410 billion in less than six weeks.
We can limit the intelligence Artificial

Now is serious discussion, proximity to situations where machines can go beyond human capacity were openly discussed in Washington DC, an event sponsored by the Information Technology and Innovation Foundation (ITIF), and was discussed whether surpassing human intelligence, machines place in check point the human.
The matter was reported in the Computer World and is philosophical concern
of philosophers such as Peter Sloterdijk, Hannah Arendt and Heidegger Ernest, but it is also curiously expected as singularity point,
The researcher Stuart Russel, professor of Electrical Enginnering and Comptuer Sciences at U.C. Berkerley said:. “We’re all working on pieces of it…. If we succeed, we’ll drive the human race off the cliff, but we kind of hope we’ll run out of gas before we get to the cliff. That doesn’t seem like a very good plan…. Maybe we need to steer in a different direction.”
Russell was one of the five speakers on the panel today that took on questions about A.I. and fears that the technology could one day become smarter than humans and run amok.
Also the physicist Hawking, who wrote A Brief History of Time, said in May that robots with artificial intelligence could outpace humans within the next 100 years. Late last year, he was even more blunt: “The development of full artificial intelligence could spell the end of the human race.”
The Internet of Things benefit the development

The potential economic value of the Internet 
of Things (IoT) is being widely underestimated, and it could be worth more than $ 11 trillion a year, according to a new report by the McKinsey Global Institute, see in Washington Post.
The Trade Marks Registry gives six reasons why the IoT is being underestimated, which includes the sub-use of data generated by various sensing devices and other networked devices.
According to the institute’s analysts paint a big-picture economic outlook, seen exclusively in industrial sectors, while there is the primary concentration of opportunities in the market to Consume Commerce (business-to-consumer) of IoT and is missing a potentially much larger opportunity the business-to-business.
In addition, about 40% of the IoT’s economic value is fed by the interoperability device, which obviates the revenue opportunity in software and hardware for this.
McKinsey also argues the impact of the Internet of Things on world economies in development are underestimated and that these savings benefit of about 40 percent of economic gains compared with about 60 percent share of the developed world due to a mistaken view this is only for the advanced world.
McKinsey speculates some developing countries will be able to overcome the advances in developed countries because the installation of equipment or infrastructure with sensors and actuators will become a problem solved.
Finally, the Internet of Things will support new business models that are likely to correlate with how data is tracked and evaluated in real time, making the frontiers of technology and and no-tech companies can not be confused.
