Opinion polls show that many of the friends support phone 4K screen

　　Hello, Mr naughty resolution. For screen resolution problem, we always have a great deal of controversy. Of course, especially the Sony launched the world's first match of the 4K of the screen phone, disputed even louder. Think cell phones should go with a high-resolution screen and now the phone don't have to match high resolution screen of loud debate, and opposition appears to have the upper hand, especially in the 4 k screen performance in the tests a little bit worse.

　　Basically, 1440 x 2560 resolution (that is, we often refer to 2K screen) are standard for many flagship Android phone, that do not support cell phone equipped with 4K the reason is that a few of the screen, and the main reason is, we think, to some small detail improvements and more take the cell phone power and sacrifice the phone's performance, is simply not worth it.

　　To this end, the foreign media on the current 4K screen should be configured to do a poll on your cell phone, the result took everyone by surprise, 17% respondents, regardless of the cell phone's screen is small or large, mobile phone 4K screen is well worth it.

　　And 44% of respondents was obviously very rational, they think 4K the screen is good, but they only support in 5.5 inch or larger screen 4K screen on a Smartphone, they think cell phone go with 4K the screen is of great significance, even though they want cell phones to be more smooth and more efficient. Another 39% of respondents believe that regardless of the phone's screen is small or large, 4K screen is not worth it, it's a waste.

　　From the poll, we found that supporting phone matches 4K accounted for the vast majority of respondents of the screen, 4K screen, after all, represent a progressive, is a future-oriented direction, although now smartphones match 4K screen is temporarily unable to give full play to its advantages. But we also found that 4K became the mainstream of flagship Android phone the screen match also does not appear in the short term, at least the recent exposure of Samsung or LG's flagship phone, still evades 4K screen.

Design is to dare to think see earplugs do skyscrapers

　　You may have seen recent news of Zaha Hadid's name. Japan Sports Council announced that Zaha Hadid was replaced by another design for the design of the Olympic Stadium in Tokyo that disgusting, alien-like architecture. And now, her Australia Melbourne designed a new skyscraper, it looks a bit like an oversized ear plugs.

　　Zaha Hadid and her partners work Plus Architecture designed the skyscraper that looks like in-ear earphones, she wanted the building to be able to reinvent the small city's skyline. According to the introduction, in the new design, new skyscrapers is described as "a series of smaller stacked vase", so that there will be such a layer after layer of undulating appearance. If you see the design renderings, you'll see that this description makes sense:

　　This stack to some parts of the Interior of the skyscraper curved design, improves the energy efficiency of buildings, as well as outdoor green spaces to provide additional space. Stack on top of each vase like this design is somewhat similar to Pritzker Prize-winning architect designs in Brisbane. Zaha Hadid by stacking designs for the building to produce rolling texture, she created some really interesting work.

　　However, don't you think up the vase looks a bit like what else do? from a rendering perspective, the skyscraper is a bit like a high-quality silicone earplugs, right? we see a pair of slightly flat plugs:

　　This silicone stacked way to make high quality earplugs that separates the voice outside the ear canal. Surrounded by Zaha Hadid designed the skyscraper outside of filigree jewelry equals high quality stuffed with the use of silicone. In design, she said: "compared with the traditional skyscraper design, new stacked skyscraper in terms of energy consumption can be reduced by half, outside of the filigree design can reduce absorption of solar energy and buildings emissions. " Moschino iPhone 6 plus

　　In addition, Zaha Hadid also joined in the skyscraper an efficient central cooling system and lighting system, high quality wastewater reuse system has also been taken into account, the purpose of which is to reduce energy consumption, further energy-saving and emission reduction. Zaha Hadid designed such a building is designed to open up the ground level to improve pedestrian flow, and make use of a wealth of connectivity and the existing transport infrastructure to bring a better urban experience.

　　At present, we don't know if the skyscraper will be quieter than traditional building. In addition, the new 54-story skyscraper designed to be Australia Ministry of planning approval.

Scientists develop self healing sensor electronic skin not far away

　　Beijing time on November 19, according to technology website TechRadar reports, Israel Institute of technology chemical engineers invented a sensor that can heal, which can be completed in one day to repair its own injury, will play in electronic skins in the future. With the development of technology, all kinds of flexible electronics began to emerge, they are widely used in wearable devices, robots, medical and aerospace and other high-tech fields. However, due to technical limitations, flexible electronics today are too fragile, accidentally breaks down. Paul Frank iPad Air Case

　　Don't worry though, technology is always evolving. This does not, Israel Institute of technology chemical engineers invented "self-healing" flexible electronic chips. Next, scientists could use the technology for people with disabilities create electronic skins. It was reported that the prosthesis after covering this type of skin, people with disabilities can perceive the surrounding environment.

　　The key is a new type of synthetic polymers, polymer containing high conductivity electrode and gold nanoparticles. When damaged, and it expands to fill the void in case of outage, affecting the normal operation of the equipment.

　　In its report on a material, the researchers wrote: "with the technology of resistor-healing effect is very powerful, even if it is cut into a few paragraphs, the sensor can still work properly. "

　　Healing one of the sensor for the, but also the skin expert Chen Boying (Tan-Phat Huynh), said: "not from the sensor will become a new platform for biosensors, real time monitoring of human health helps skin. "

E SIM cards have any good why did Apple Samsung persisted

"Editor's note" technology advances faster than we ever imagined, when we were still worried about how to protect the SIM card information safe when E-SIM card will be poised. The joint was popularized by Apple and Samsung, the two "enemy" giant on the E-SIM technology come together. Put aside the interests of constituents, we are more curious about is the power of technology.

According to the financial times of London reported, with the exception of supply chain cooperation, Apple and Samsung has started in another area, and actively to persuade operators to tie your own development and to use the new SIM card standard, this new SIM card by using embedded technology (later known as E-SIM), could make it easier for mobile devices in switching between different operators ' networks.

Earlier last year, LTE release of iPad on Air2, a step ahead of Apple by a similar programme, its a Apple SIM card is built-in, users can work directly from a set of equipment to use to purchase data services operator. But apparently, when Apple is only a small step.

On one hand, we see the famous Apple SIM card operator is still relatively limited. And this led to the problem is that the Apple iPad Air2 more SIM cards can only provide experimental, it does not have the capacity to fully convince users abandon external SIM card, so iPad Air2 is still reserved for the SIM card slot.

E-SIM card what is the principle? Michael Kors iPad air Cases

"SIM" name is "Subscriber identity module", or "Subscriber identity module". Its main role is to store data, including some fixed data.

As the international mobile subscriber identity (IMSI), authentication key (KI), the personal identification number (PIN), the MDN (mobile phone number), as well as the SIM card security algorithms and data content, key, network traffic so that users know their identity, found different users and establishing communication and billing in accordance with the appropriate tariff policies.

At the earliest time, CDMA mobile phone there is no SIM card, instead of burning, including early Hai Tao iPhone users also have met the telecommunications unit burned. Zhihou, popular GSM devices become mainstream-although the SIM card for a long time, and did not significantly change the nature of the SIM card.

But led by pioneers such as Apple, SIM from appearance but has "shrunk" trend. Although its scope is limited to the surrounding plastic card tray, but it is easy to see, miniaturization has been successfully validated is a SIM card in the right direction. Even it was suggested that the SIM card should you want to cancel the physical form, transforming it into a software form, for the latter, we call it "virtual SIM card".

And the so-called E-SIM, strictly speaking is not a true virtual SIM card. Its main significance is that if E-SIM card equipment, then users purchase their cards after the device is no longer needed, but directly by software registration or direct purchase and other types of ways you can use your own operator's network and packages.

Prior to that, traditional SIM cards do is locked by means of binding the user in a service network. Integrated E-SIM card, allows users to avoid limitations in the services of an operator.

Let us take a very common case to illustrate the meaning of the E-SIM card, which is roaming abroad.

Assumptions before we are using China Mobile SIM cards and opened roaming service before going abroad if necessary, went abroad, we have access to the local network, local operators will be issued to mobile authentication information. After the user opened roaming service, which creates a difference in virtual IMSI SIM card before, so that we can be ATT's network for authentication by, then we can use its services. However, if we wanted to use local operators and services, still need to apply for a SIM card only.

So now, after you have your E-SIM card, we will not so cumbersome, you can freely choose a different network. And need not be limited by high roaming fees, directly to the local price to enjoy the different operator's service. And implementation, by the agreement between the operators or by negotiated purchase package the terminal manufacturers and operators to provide to the user.

If the SIM card from scratch before, solve the problem of phone users don't get replaced, from the traditional SIM card E-SIM card, solved the problem of is user bound by operators, which not only simplifies the process of user network sign up, also significantly reduced the cost of user changing operators.

Impact on operators

E-SIM card unit and burned many places are similar, but its results are completely different, because their respective symbol of user operators rely on light and heavy.

It is, therefore, from a certain point of view-

E-SIM card for users of the Gospel, is a challenge for operators.

Prior to that, as the only mobile operator to issue SIM cards, global carriers through the SIM card and phone numbers bindings, firmly locking a large number of users, and with users of voice and data consumption and earn big bucks. While SIM card is proof of ID for each user and network, for more than 20 years in, for operators to build a solid defense line.

Based on this, operators gradually developed a monthly rental, packages, as well as subsidies and other business model, as long as users continue to use this number, it must have consumed, in this context, terminal manufacturers are happy to work with our operators, together to urge the Terminal generation, achieve win-win situation.

But are because this, SIM card while is operators of died points, if one day operators no longer can master SIM card has, so also on means with it will was forced to alienated user--E-SIM card of coming, on brings has such a problem, those select E-SIM card of user, may no longer will and a a operators signed Xia long-term contracts, and has may at any time left, and this for operators margins and business mode of effect is is huge of.

So we see that, although the majority of operators have opted to join the embedded SIM card standard to, but for large operators, put the choice to the user is quite difficult, the trend is relatively favorable to service small and medium operators.

Of course, operators have recognized this trend, it does not mean that E-SIM card can quickly fall because this model after all operators a revolution. And though you see Apple and Samsung both world number one or two mobile phone manufacturer's blessing, but since carriers subsidize the factor exists, even if they can only appeal and take the lead model and not necessarily decisive in the development of E-SIM card.

E-SIM cards have hidden it?

Earlier have been introduced E-SIM benefits to the user, it is convenience and freedom was greatly improved, and a decline in dependence on carriers. However, the E-SIM cards are also not completely safe. Because it essentially is the same logic as the original SIM card, just become embedded.

And Qian soon was exposure out of global maximum of SIM card manufacturer Gemalto suffered hacker invasion of event, on proved has SIM card this a was general think is security of system also exists defects and vulnerability, in its itself no for reliable of security upgrade zhiqian, regardless of is outside plug type also is embedded type, results and not has more big difference--certainly has, from big of environment Xia we also is without concerns SIM card of security problem of, more alone it also not hamper we for E-SIM card this revolution of support.

Also worth mentioning is that the E-SIM card as much as virtual SIM card completely, but compared to the virtual SIM card and only a few vendors can master the premise of E-SIM card is clearly more pervasive. Because virtual SIM card to replace the operator's work is feasible from the system or baseband start agreement to bypass carriers, which is why only Apple and few vendors such as Huawei to launch services's sake, but for most companies, and the relatively high threshold for such programmes.

Then the problem came back again, number portability network in the country for many years still in shortage "landing" State of the environment, when we can enjoy this service? Michael Kors iPad Air Case

World s most expensive materials 1 g to sell nearly 1 billion yuan

　　Diamonds are very expensive right? There is now a much more expensive than diamond materials was born, price per 1 gram of £ 100 million, which is about 965 million Yuan. Louis Vuitton iPhone 6 plus Case

　　According to foreign media reports, the Oxford University set up carbon-materials design company has developed a new material, this new material known as Endohedral Fullerene (Fullerene embedded), is composed of carbon atoms of the cage structure, containing nitrogen atoms of the cage.

　　This material can be used to do? Manufacturing of small portable atomic clocks, so that no one is driving a car GPS navigation system accurate to 1 mm. Atomic clocks are the most accurate timekeeping system.

　　Driverless car is the car of the future, atomic clock to ensure the safety of unmanned. Drone is clearly a highly attractive technology, it is now on the way to, you just need to relax and get in the car, do not need to enter any command, where it can take you wherever you want to go.

　　These driverless cars, better known is Google's driverless car. Google is rapidly expanding its drone fleet, before news that Google plans to achieve Google's driverless car production in 2020, while the company also plans to produce this year about 100 vehicles driverless cars.

　　In addition, Google has also said that the unmanned vehicle mileage has exceeded 10000 miles a week (16,000-kilometer).

　　Other than Google, other car makers are also studying the unmanned technologies, such as aotesila, Mercedes-Benz, BMW and Audi, Audi cars no one else has put a lot of effort, and some achievements have been made, even announcing in 2017 will be foreign sale of unmanned version of the A8.

　　Reportedly, a small portable atomic clock technology will be widely used. The most obvious is to control a driverless car. If two cars travelling on a country road, is not enough for their positioning accurate to within 2 meters, accurate to 1 mm is enough.

　　Reported that the current GPS precision can only reach a few meters, for the introduction of driverless cars, this is a big challenge.

　　Reported that the carbon atoms exist in many forms, including the diamond and Graphene. The Fullerenes consist of 60 carbon atoms, because of its shape, was nicknamed "Bucky balls".

　　Carbon materials and design company, has started to sell "nested Fullerene" material, the total weight is 200 micrograms, sold up to 22,000 pounds.

　　Oxford early investments in technology investment in the start-up Fund has invested £ 75,000, for carbon materials design company in Oxford last year grant of £ 75,000. Louis Vuitton iPhone 6 plus Cases

　　Oxford technology fund managers say holding a stake, atomic clock as big as a room now. This inline Fullerenes can make atomic clocks small enough to be installed on the chip, so as to put into your mobile phone. One day per phone, will contain such material.

Stanford management development Eero router three groups to eliminate blind

Relying solely on a router Wi-Fi for the entire House is not ideal, there's always signal blind spots. San Francisco startup Eero thinks he has a way of not relying on signal amplifiers to solve this problem.

Instead of using a router, Eero encourages you to take advantage of those through the mesh network connected devices, building a distributed network. A device sold for $ 129, three US $ 299, the company said three can provide good signal coverage for a family.

You need to install first Eero will be associated with the existing cat. The appearance of the product is designed by industrial designers Nest one of Fred Bould, configured as follows:

2.4GHz and 5GHz are two frequencies OtterBox iPhone Case

Bluetooth 4.0

1GHz processors

512MB memory

1GB storage

In the development of hardware at the same time, Weaver's team is also working to create new software:

With a cloud based control panel to monitor the network, supports both Android and iOS applications for remote viewing

Reminder settings in the application, whenever there is a new device has joined the network, a reminder message will pop up

By applying directly to share with visitors the wireless signal

Integrated Bluetooth capabilities, Eero can be easily connected with the family in the next few years a growing number of connected devices.

Eero's CEO Nick Weaver said, designed the original intention of this product is:

"How we design the Wi-Fi system, could provide wireless connections for different sizes of houses? "

Why should I choose install Wi-Fi connection points distributed in a House? Weaver simply summed up as: you never try to use a light bulb to illuminate the whole House. The same principle applies to wireless products.

Eero also promises its performance to be significantly superior to traditional signal amplifier. Cheap amplifier has only one wireless connection points, you need to use the conversion between them, which will undermine the bandwidth and performance, and will have more than one network. Eero system only generates a unique network, by the given device automatic connection.

He was still in quite a long time to solve the problem of unreliable Wi-Fi.

"I am a trained engineer. I often make settings for the wireless network, but there is no increase in the past 15 years. I study at Stanford University, where I work as a network administrator. Even in the network research at Stanford, the software remains a difficult problem. "

Eero seems to solve this problem, but we have reservations until we get system.
