IoT and upcoming future prospects

The IoT seen as a paradigm of a changing society may change, among many other 
things, cultural libraries and equipment allowing greater interaction with users and providing new services, some of which may come from applications in the clouds.
Most of the objects that surround us today will be in the network in one way or another, so that you can have complete information about each one of them, it will be necessary to use repository in clouds, information sharing and data reliability.
Among the technologies for identifying objects are radio frequency identification (RFID) and sensor networks that will grow to meet this new challenge, what will be the new information and communication systems that will be present, although invisible to the user, Which will have an environment around us.
This will result in the generation of huge amounts of data that must be collected, stored, processed and presented transparently, efficiently and with intuitive interpretation by the users, ie simplicity and efficiency summarizing.
This means that model will consist of these services will become commodities as products and should be delivered in a similar way to traditional commodities.
Cloud computing should provide the virtual infrastructure for such utilitarian computing that integrates monitoring devices, storage devices and should behave both analysis tools whose foundations are found in Information Science, as visualization and delivery platforms to the customers, whose foundations are Both in Information Architecture and in Information design, this being to express beauty and help in the intuitive environment.
The model needs to consider the cost that Cloud computing offers, that is, the service must be end-user accessible to users and businesses to access on-demand applications from anywhere without the user’s chatting.
Intelligent connectivity with existing networks and computing able to use context to handle network resources will be an indispensable part of IoT.
An internet that in addition to current applications including sensors and actuators connecting the physical world should emerge consolidating IoT.
IoT’s progress is only beginning, but the period of mistrust has passed.
Chip revolutionizes IoT

A company almost bankrupt decides to invest in the development of a chip for the 
Internet 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

According to Peter Burke, the locu
s 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

IoT (internet of Things) is there, cars, clocks, medical equipment and other devices 
are 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
CES 2017 started

Jan
The largest electronics fair in the world, which marks the 50th anniversary, started with 
more than 20,000 products to be launched, the Consumer Electronics Show in 2017 can be accessed by some sites that are broadcasting it live, of course some events, because the The event is an immense courtyard larger than the Anhembi Park Exposition of São Paulo.
Some products have come before in the market, Amazon’s Echo, for example, was a Christmas phenomenon and the sale sold out the week before the parties, the suggestive name is because you enter your home and an echo answers you, a Devices.
Samsung has launched, for example, a vacuum cleaner that connects to the Alexa system, but it has its own voice system that is SmartThings.
New TVs with advanced 4K OLED technology (called QLED by the definition of colors), and medium smatphones like the Samsung A7 (5.7 inch screen), A5 (5.2 inches) and A3 (4.7 inches) are trends.
The wearable ones, which began with the pluggable clocks, now go to other products like a scarf that measures and filters the pollution and can even connect to a sound amplifier (launch of the LG) that is in front of the neck, we remember that in the northern hemisphere it’s winter and here is summer
The drones are more accessible, simplified and modular, there is a curious launch of the GDU that can easily connect a camera to firm something near your home or explore a region where you are and make filming.
Another trend already clear is virtual reality and augmented, pokemons are just an application of this technology, the Oculus Rift glasses, the market since 2013 and the Playstation VR are already there, now the promise is a technology incorporated into mobile phones and more friendly.
The cars without drivers are already there, last year the Bolt was a success, now new cars are being expected from Ford, Honda, Volks, Hyundai and Toyota.
Cyborgs and androids, still stand for science fiction, just cute little robots like Egg

IoT points in 2017 The company’s technological forecasts Gartner analyzes
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.”
e-Estonia: a digital country
25
Oct
Since its independence from the former Soviet Union (20 August 1991), 
Estonia decided it would be a country that would remain connected, decentralized, on an open platform infrastructure and a continuous process to keep improving, calling it four principles in its site.
The two key points of this e-citizenship is the identity card or e-ID and decentralized connection called infrastructure X-Road, they open the door to all state services, social and economic data, and the eID identification able to verify the identity of a person around the online environment.
The people of Estonia are the source of the Phoenicians, but are intimate and ethnically related to Finnish and Sami (northern Norway), so with historical links to all of Scandinavia, and the port of Tallinn as its capital and largest city, with the all over the country about 1 million and a half inhabitants.
With this economy has benefited from the strength of the electronics and telecommunications sectors and strong trade ties with Finland, Sweden, Russia and Germany.
The system of government is parliamentary with a Congress of 101 deputies elected directly by the vote of the citizens.
Estonia joined the European Union on 1 May 2004, while Latvia and Lithuania, has a GDP of US $ 35,398, which gives a per capita income of $ 26,000.
Smartphones catch fire?

Oct
No, of course great care must be taken as not to leave for long time in the making,
avoid turning on when there is too much variation in voltage, etc. but recently it happened some cases that drew attention.
The mobile technology Samsung Galaxy Note 7 caught fire in the US, despite the company having made a great product recall last month, and the case drew the attention of the company.
As the Commission of American Security Consumer Products (CPSC, acronym in English), in an official report last month (15/09) 26 incidents with burns had occurred in the United States, and the alert was triggered.
Complaints started happening last month, and were sales were immediately suspended in the 10 markets where it already sold, but Brazil had not yet received the product.
Samsung has received 92 reports of batteries overheating in the US, of which 26 are reports of burns and other 55 material damage, like fires in cars or garages, the CPSC advised consumers to switch off appliances.
Prior to these reports the number set of fire in smartphones in the world could not reach a dozen and many were cases of misuse, leave plenty of time plugged in or high voltage variations, it is not to cause any alarm.
