Latest sweat sensor or promote research and development of next generation wearable

　　Wei Feng network on January 28, wearable device has been gradually rising in recent years, and such devices, sensor is critical. After all, wearable devices only support of the sensor will be able to play the largest role. In addition, such devices are often linked and exercise and health. For example, calculate the number of steps or remind people to exercise, and so on. Based on these characteristics, researchers at the University of California, Berkeley, recently developed a new sensor will be able to better promote development of wearable device.

　　This sensor is based on body discharges perspiration to determine the physical condition of the wearer, and timely reminder of what they should do to check or adjust. Researchers said to flush out the sweat has a wealth of biological information, is the human health situation in one of the most intuitive way. And in sweat, this information is very complex. But now that they have overcome the technical problems, you can extract useful information for analysis of sweat, these data after processing to the Smartphone.

　　And now, they have developed a complete set of integrated systems, and developed it into a platform for health monitoring technique based on sweat. Brooks Professor of Integrative Biology, University of California, Berkeley said: this study contributes to the development of the wearable device, and to improve people's health, for modern people, it is very important and very crucial.

Optimized Android underlying firm harder the more tangled

If seriously, Android's "bottom" where? In the article, Lei feng's network reporter roughly describes the true meaning of what Android underlying so-called also noted that mobile phone manufacturers in promoting "the underlying optimization", the struggling in this area.

Then again, regardless of mobile phone manufacturers in Android at the bottom do not have the ability to optimize, if they are determined to change users on Android mobile phone cards, slow, hot impression, a lot of optimization work and not so "deep".

More with more card Android phone

Android mobile phone cards, slow, fever, the fact that crashes are a simplified, complete description should be: after a long period of time, hands on the iPhone is that the iPhone and Android mobile phone has "hobbled".

Are afraid of contrast, where is the Android phone is the problem? Wu Zhangjin Meizu software engineers from two dimensional analysis of causes. First of all, when mobile hardware remain fixed when software upgrades for the following reasons:

1, mobile phone memory chips, along with the natural slow;

2, aging hardware and all kinds of falls result in damaged parts;

3 aging resulted in an increased energy consumption of mobile phones, devices and contacts, system temperature control is triggered after the fever, causing CPU block cause the system to slow;

4, a new version of the firmware without considerable development and testing investment optimization is not in place;

5, almost every version is much more resources (more memory and Flash)

Should note is that these problems are not unique to Android phones, believes those who have complex of iPhone 4 users on this experience should have been. Of course, Android mobile phone software upgrade special is that it is faster, the ROM every Monday is already the norm.

The other hand, even if a user understands that, after you bought the phone don't update the firmware Android phones in use as far as possible be the size it? The answer is no, for the following reasons:

1, the software runs in the background more, default increasing load, reduced idle processor resources;

Superposition of 2, background applications, memory consumption gradually increased, resulting in decreased free memory (new tasks start or old tasks require memory resources back to the front desk may need to trigger the zram swap or lowmemkiller, which will inevitably bring about delays, and any memory leaks or even reclaim memory can cause the system to collapse);

3, when the application resides in the background after the flood, with the increase in memory consumption, memory fragmentation can be serious (is physically contiguous memory will be less and less, which can lead to serious IO performance degradation may cause the IO operations from order to random operations);

4, applications increased causing the system to more easily fever, triggering system temperature control, which led to block such action;

5, part of the temperature control technology into reduced FPS (refresh rate), this can influence the user experience awareness (which is understandable, of course, balancing hardware after curing fever and has been the only way)

You can see from the above, except the last one is outside the interest equilibrium in mobile phone manufacturers a choice, much less restraint in third party applications. LBE security master CEO Zhang Yong was quoted as saying: "this is a long game of cat and mouse. "

Game of mobile phone manufacturers and third-party applications

As we all know, Android application developer permissions is very large, allowed since the start, allowing the permanent background, allowing automatic networking allows real-time push and so on. Not to second-guess what Google was designed, see from the results, which are sets of rules applies only to utopia.

Zhou hongyi said in media interviews: "on selected phones (application) we will conduct technical evaluation, not a BUG, it must be stable. They (the application) cannot upload user data without permission, not secret behind Networking cannot be privately consuming user traffic, the most important thing can't always wake up themselves, without the user's knowledge of the circumstances in the background, doing a lot of work, and finally phone memory are consumed by application of these. "

Words go straight to the user pain point, odd cool cell phone not listed, Lei feng's network on these issues in LBE interviewed Wang Mingyang doing similar work, he says security software provided by Root, can be injected into the target program to dynamically modify its permission and started now prevent third-party applications "bullying" many have matured.

According to Zhang Yong said the optimization of mobile phone manufacturers to apply permissions to work primarily at the framework layer. But after a lot of work has been done, in the mobile phone on the back of, "there are still many grey areas, such as mobile phone company calls Google map may be acquiring location information, but the phone Baidu Baidu is called Mobile guardian may be pulled alive. They are technically the same, only different and react differently as a result. "

Technically indistinguishable, in theory, can only rely on manual review, iOS is doing. Android cannot do so, because "these are two companies (Apple&Google) design philosophy and ideas of different causes. "Zhang said.

In addition, in addition to start and manage outside, push mechanism and the focus of optimizing care objects. For some reason, Google Push channel temporarily unavailable in China, so each user can realize "real-time notifications", must remain "connection slow heart beat" rhythms. In this case, even leaving aside the harassment aside, for the weak power of the Smartphone, this simply cannot afford.

Millet Ji Ma network reporter from Lei feng, Director of security, said prior to the Google Android and scheduled wake, MIUI does this optimization, that is, "hold each application's wake, unified system to the specified point in time to perform. "Such a move will not simply turn off all programs missing messages, nor too much burden on the power. Disney Note 4 Case

Android handset makers through various technical means, to a certain extent to restrict the application of the abuse of rights, but the effect is difficult to par to iOS. The reason is simple: the iOS does not open these permissions, Android instead, mobile phone manufacturers are, as appropriate, to recover, "as appropriate," the word covers too many variables.

"Either fast or die"

Talk about optimization of certain details, Wang Mingyang told reporter of Lei feng, nature of the gap between Android and iOS are not in these areas, "iOS code runs directly on the CPU, and run Android on a virtual machine, so the same hardware configuration, Android implementation than the same iOS consume more resources. "Therefore, in his view, upgrading the hardware to be more reliable than the underlying optimization, and Android mobile phone hardware changes much more quickly to.

One occurs in a cell phone manufacturer's case is typical: when several software engineers worked hard for months, and finally phone to a satisfactory level of performance optimization, component upgrades, slightly increasing hardware costs to the mobile phone has brought better performance. Even the engineers still determined their work is valuable, the leadership also for the measurement of input-output ratio, the necessity of thinking into doing this thing.

Wu Zhangjin, said: "on the current domestic situation is concerned, part of the big manufacturers are also largely confined to the hardware features on the stack. Some manufacturers will invest in UI design, hardware, look and theme of ROM and a variety of interactive optimization. Small (manufacturer) struggles to do the basic optimization of stability, reduce the chances of system freezes, crashes, or restarts. "

On these issues, of course, not every one can get answers within the validity period, so "many products because these questions are difficult. Some products remain in the pursuit of solutions to various crash restart Bug, few systematic solutions such as RAS. "

Whatever measures taken today, including mobile phone manufacturers, Apple significantly accelerates the rhythm, a well-known domestic mobile phone manufacturers when it comes to their situation is now playing is "either fast or die", so a lot of optimization work still can't keep up with the slogan created by the demand.

The only positive is that the current standard first-line Android handset, whether it is the management of third-party applications or their own understanding of the hardware/software are maturing, they gap has with the iPhone than a stereotype to shrink a lot. But in Matthew continues to heat up today, to honor "the underlying optimization" promises to be more urgent than expected.

Can you walk in front of the latest smart stroller

　　Wei Feng network on January 21, with children is a big deal, but in trouble, but also would be very happy. But for many mothers, sometimes still find very convenient. Thus, many mothers choose a stroller. After all, baby car, mothers will be able to buy vegetables to go with a baby or something, which is very convenient. Even so, if something in his hand too much, will still be very laborious. Paul Frank iPad Mini Case

　　So, someone came up with this idea: If you can make a baby carriage followed automatically, you can solve this problem. Now, perhaps this really is implemented, this intelligent named Smartbe Stroller strollers will be able to meet your needs. It can be paired with your watch or cell phone, and control through the smart watches or mobile phones. When you choose to enable automatic follow feature, it will follow that match the equipment to move it.

　　In other words, whether you want to jog, or because something inconvenient in hand carts, just opened this feature, baby carriage will follow, which is very convenient. Of course, this stroller also has some other features. For example, it comes with an air filtration system. As long as the mobile phone operation will be closed up and open the filter system, you can make baby breathe safe air in the car. Believes this feature for people near Royal Park, it is very useful. In addition, it can also be used for playing a lullaby. Paul Frank iPad Mini Case

　　And for the price, I believe you have thought, not too expensive, this stroller retails for $ 3199. For most wage-earners, which is very expensive. But if you have the means, I believe this is a very nice piece of equipment.

How to copy Path prequel forget the private social networking

Given the purpose of Lei feng's lab is broken the product and read the market, so the C2C (Copy to China) was not opposed by Lei feng's network. Instead, how to handle a copied object and core on its products effectively copied and survived, this is a very good developer to do it.

Especially for the Path. Path is a service, the service is so simple that no technical barriers, then the key is to seize the Path of core products, as well as how to integrate available resources. Of course, the Path with an official saying "private social networking", but this vague concept is precisely the protection Path best smoke. In the evaluation, we can see some mindless copy or copy all copy is not like case, it might just be the "private social" way.

Lei feng's laboratory believes that Path core is to strengthen the liaison between the mobile phone address book friends and sharing. Path quickly and easily available to the user of such a feature: other than the text messages and phone calls, and another one contact phone book, click one or more contacts.

Lei Feng is the environment test laboratory: phone calls and SMS not in use cases, user a tells b, themselves and their friends in common with user c. Test results are as follows

OK, this is not fair, because the test content is tailored for Path. But you can see from the test, orientation of Path is to meet the needs of applications in this environment. Inform specified or not specified friends, his social status in real time--this sentence does sound familiar?

Yes, Path of the product concept is Foursuare products evolved. Path does not impact Facebook Kik's influence in the mobile terminal, because they each have their own advantages of function and environmental orientation. But the Path can be fully leather Foursuare life

Mobile social networking platform for product ideas, from the evolution of Foursuare to the Path? Ted Baker iPhone 6 Plus Case

1, go to the WEB. Almost all the Foursuare the sign in application, there is a flow of small WEB sites, and inherited the traditional bad habits lead to function on the WEB of the Internet, even more than mobile clients or WAP. And if you take the traditional Internet websites, can bring at least one benefit: new users are no different. No one will try to login WEB version of this product on a PC, and then see what social platforms with their similarities and differences. Go to the WEB, is to remove one's competing products, and to clarify their position.

https://www.youtube.com/watch?v=BeGOVM-FtmE

2, the address is not a core service, addresses only one of the automatic messages. In Foursuare appears at the beginning, users share their current address formed a short-lived trend. But this trend did not last long, because the address information is not rich, or better to play. In fact, you can share information other than addresses automatically, there could be weather, expression and peer ... ... From a narrow shared addresses, to share various automated information, including addresses, is a big step forward for sustainable development progress.

3, user network data mining. Foursuare is a network of apparent strangers and did not facilitate the design of strangers know each other and Exchange-usually this is imported into other social networking platform has. As a result, application of the Foursuare class, it's hard to get can analyze data from a user's network, while Path much easier--of course, in this regard, Tencent and Facebook is boss. But Facebook may not be well-versed in each user's mobile phone address book, Path is known. Result Path after one year in operation we can effectively recommend users who might know, and this is undoubtedly necessary to operate a long-lived social products.

4, the most important and most unrelated technical point: the Path of design tide, cooler, more sense of science and technology. Are you tired of boring like a traditional browser columns and simple dropdown refresh it? Then, you can uninstall Foursuare.

View Foursuare's Chinese disciple, have almost all changed thanks to the mass comment nets as a teacher, Lei feng's lab think, or do not continue to black anymore.

To guard Earth NASA new planetary defence Office

　　Take it easy, people on the Earth, you should be able to get a good night's sleep tonight: United States Space Agency (NASA) has just set up a new Office – a planetary defence collaboration Office, the purpose of which is to "fix" that may bring about doomsday asteroids to the Earth. Alexander Mcqueen iPhone 5

https://www.youtube.com/watch?v=VZ5S32Fxfpo

　　It is understood that the Planetary Defense Coordination Office will be responsible for all of NASA's detection and tracking of work related to near-Earth objects, if that's what it takes, it will also work with other federal agencies, as well as other countries. Lindley Johnson of the leaders of the Office even has a very cool title: planetary defence officer.

　　In recent years, the United States Aeronautics and Space Administration to avoid Earth suffered a devastating, has stepped up its efforts, United National Nuclear Security Administration recently conducted a study on the use of nuclear weapons of the asteroid's orbit scheme.

　　United States Aeronautics and Space Administration said, if they and other international organizations are not able to leave the asteroid it orbits, the new Planetary Defense Coordination Office will help humans on Earth for emergency preparedness, will also issue a warning notice to those potentially affected areas, and to assist emergency response agencies such as the Federal Emergency Management Agency for work.

　　Lindley Johnson in the United States said at a NASA press conference: "it is obvious that planetary defence cooperation is formally established in the Office of United States Aeronautics and Space Administration to the detection of natural hazards, develop a sign of defense planning. "

　　In addition to new offices outside the leader, Lindley Johnson also is a near-Earth object program Executive, now it has become part of the new Office. United States Aeronautics and Space Administration have been identified every year approximately 1500 new near-Earth objects, the Agency thought they had found an 90% greater than 3000 feet or more of near-Earth objects.

　　Now, they want to be able to detect smaller, but still potentially dangerous near-Earth objects, they are about 450 feet in diameter or larger. About 75% of these near-Earth objects was still not found.

　　From United States officials of NASA's Science Mission Directorate John Grunsfeld said in a press release: "asteroid detection, tracking and protecting the Earth are United States Aeronautics and Space Administration and its partners in a major role. Although there is no known planetary collision threat, but 2013 car ya bin g Super Fireball and the recent Halloween asteroids are reminders that we should remain vigilant, and expressed concern about the sky overhead. "

　　According to United States Aeronautics and Space Administration said, in last month's federal budget, including the near-Earth object observations and Planetary Defense of $ 50 million, and in 2010, the budget of only US $ 4 million.

The established mobile developer Office

Finally want to get in on the mobile Internet at the Ministry shortly before news spread panic, but there has been no clear explanation, the Ministry's official statement is ambiguous, approval for a commercial business licenses, to record non-operating business, but this does not give the individual developers and small development groups for more information.

Telecommunications Council of economic experts at the Ministry Secretary-General Chen Jinqiao told the media: "the Ministry will establish an effective evaluation system, to App platform for third-party integration, set up needed for the record, running to monitoring. Individual application development must be integrated into the management system, but also to real-name authentication, and so on. And the Ministry would improve after filing – oversight – audit--spot checks and other means. "This speech was rather clearly pointed out the direction of future policy development.

There are many small and medium developers worry that it might cause themselves to lose their eligibility for developing mobile applications. Although the Ministry "Tigers not only flies" commitment, but it does not make these people feel at ease. Hermes S6 case

But always, its guiding role than the features described. Ministry if it does "meddling in the mobile Internet" as the guiding spirit introduced a series of regulations and policies will form new ecological environment in the industry--the so-called "there are countermeasures." And the ecological environment, does seem to have been more conducive to the growth of individual developers.

For example, mobile developer firm was established.

Times mobile medium and small developers in the Internet age and the Internet programmers and desktop Internet codes are not the same when mature. Mobile Internet is born in an era of online marketing is very developed, the developers work, technology and seed users, are to the brand, the industrial chain upstream and downstream, providing professional services to their users. In this situation, the mobile developers can, and accountants, lawyers and so on professional careers as professional services to the community. And this requires successfully organized firm of individual developers to gather together a large number of individual developers, this creates a firm.

Firms in this form, is undoubtedly the new trend at the Ministry most easily lead to concrete results.

Need qualification of personal developers can joined things by independent development or and others cooperation development, last results of benefit return himself fame return firm, and those success of personal developers will became firm of partner, so also has has more of resources and social status, this makes they more has power to promoted industry and social of progress--yiqian, in technology field this is belongs to giant are of privileges. But for the Ministry, and management of the firm is that they want to "shark", and firms ' administrative authorities to communicate with developers is obviously more affinity for. Although firms will result in various disputes and seniority and other industry firms. But for the majority of small and medium developers is more good than harm.

For the beginning of the entrepreneurial individual developers in the past, the necessary contacts and experience in the industry, further development of capital and resources, as well as all aspects of product development, the firm is able to provide sufficient help. Because objectively, we all have to go under in an Office, is not so easy to fall out with each other at the negotiating table. With the sharp decline of trust cost, will greatly enhance the survival rate of the individual developers in the bud--this is definitely a good thing for the industry as a whole.

In addition, a large number of independent outsourcing of product development teams, and enterprise in transition, this form can also firm, while the order and independent of the brand products business bigger. In fact, outsourcing companies have lots of mobile development engineers and programmers, many of their wisdom by the market constraints and customer needs evolve too slowly the image, was on hold for a long time. And one firm can optimize the allocation of those resources, and also the benefits arising from the exploitation of resources--maybe we can not determine the fair and equitable distribution of benefits, but only if real scale outbreak of the whole industry, is the true meaning of equitable distribution.

 

So we can go back and look at what is currently small and medium developers bitter about. Hermes S6

Is to a large extent, not ideas or technology dried up, but the market demand is not clear. Mobile Internet is very hot, but who is unable to demonstrate whether it is hot, outbreaks of market demand is still ahead, waiting for the spark to set off it-but for now, except for a few stars, most developers are scrambling to stay up – Ma said hopes to live up to that day, the app also got a stand-by ticket only, not to mention the small and medium developers?

Firm is not the only solution, but it is the industry of the future ecology of a possibility.

More life than the desktop Internet, mobile Internet consumption and trends. Mobile Internet is not supplied to users interesting products and convenient services, more social and personalized custom is no doubt inevitable direction. Single point of breakthrough in many personal developers will one day become a, which in turn changes traditional business including the traditional appearance of Internet commerce.

It takes a lot of individual developers and small teams, they just like the middle-class social structure, only stronger, the whole ecosystem is healthy.

From a different angle, in fact the firm described above form similar to a mobile developers Association or the mobile developer community. This hold together for development, complementary forms of business is very popular in Europe and the United States, particularly for learning related professional college students from the school will begin the development of this organization until one day after graduation to make some product, or an entire team joined the company. This phenomenon does not appear in the Chinese developer community. National style of the social environment and the topic too deeply, you are not here.

 

Editor's Note: if conditions are mature and developers need, Lei Feng will take the lead to set up mobile developer firms, help coordinate resources among mobile developers, providing documentation and license service, completely free, mobile Internet Lei Feng does good in middle school!

Intelligent router now and in the future

Currently, the Internet front has been stretched to the size of just about everywhere. Smart after the concept has filled every corner of life, flows pass have taken advantage of the router in the family unit on the road to intelligent. And a lot of other smart products, smart router, we would also like to ask, whether consumers really need such a product?

Now think that the router has intelligent necessary, mostly on the smart family has a comprehensive imagination of the industry or technology enthusiast, to the majority of consumers, the router is smart is not that important. Needs to be clear is, the router as a family unit for a long time one of the most humble demand, with the number of personal Internet device, will usher in a transition from to stand behind the scenes and with the increase in user demand for product upgrades, intelligent router market grows gradually.

Coverage of the router itself is extremely broad, if this time the concept of smart, and with increasing values of the router itself and the user experience, and would change the entire industry. But the ensuing, user is increasing demand for the products, manufacturers and the difficulties on the road to self-actualization.

Very hot route in the near future, for example, simple sets, Micro USB power supply, advanced modular functions, forced off wireless devices and weave his magic over the wall experience is unprecedented human attraction, also attracted a lot of consumer demand for these features. But after careful observation shows that these functions are essentially the scope of micro-innovation and the router function and nature cannot be changed. We know that the router market is hot is one of the prerequisites for personal wireless devices with growing demand, if products cannot be achieved on hardware load and optimize, the only micro-innovation and niche selling point, is not able to really let users create purchase demand and desire to purchase.

Although phase compared network engineering this complex of access way, currently household SOHO router in Web interface for configuration of simple operation has can is revolutionary of progress has; but household routing ultimately is a mass type equipment, on currently,, many consumers does not will himself on router for configuration, and very routing like of products, its App end of configuration operation and traditional of Web way and no nature difference, also on not can real help upgrade user experience.

Composition of the building and from the wisdom of their families and of things to see, smart router face there is a nagging question: because IOT is composed to link up all the most important functions of, that is aimed at all products converge as a platform. But for now, smart router cannot become a home network hub, the first being tested is the stability of the product – imagine when all aspects of the family connection, but causes total paralysis and downtime because the network, that is how bad things. And on currently seems, intelligent router by main of other function also enough stable, like wide by praise of turned wall function, has is stepped on in has policy of red on, at any time may became a rotten tail function; global accelerated function, is in early scale is unlikely to of when only can achieved of, late must will faced with was about sector ordered canceled and charges, ending; as other function, basic on stay in expected scene among, are not enough to take full of intelligent construction and user needs. Moschino new iPad case

This a fault has occurred-the traditional equipment do not meet future demand, but new equipment and can not supply mature experience. What kind of router is the smart new on the next real practical use of it?

In my opinion, a true say good smart router, should meet the following basic requirements:

Increase of 1, network coverage; Moschino iPad 4 case

2, increasing network throughput traffic;

3, optimizing network load and hardware;

4, the effective protection of product and user security;

5, easy operation;

That is, the so-called smart router, is not "smart" on the word, the ultimate significance of their products is to enhance the user experience, the essential function of the router to the extreme, laying a solid foundation for building and implementation of intelligent life. These existing vendors have done is far from enough.

Local Hello you want flying Skateboards has been developed you can order

Last year June of when, Lexus make out has a big news, they released has a short of video, hinted Institute issued has real of flight skateboard--results, dang world countless people climax have don't don't of, truth once disclosure, about on soft has: original, Lexus that goods is a "Lei Zheng rich", hanging with Superconducting Maglev of guise, Newby have low temperature liquid kept evaporation take white of, but is can't lasting, basic just hard on soft has...... Not durable.

For some time the news local tyrants who've lost the courage to live, "there is law? "They say," I have the money, they want to fly! "This just could not be ignored, so a bunch of people working overtime to crank out the goods, are said to be able to fly, and do not need superconducting environment even can order buy buy buy now: Starbucks iPhone 5 Case

Ideas from Arca Space companies, this flying skateboards called ArcaBoard, technical solution rather gross--36 powerful fan to me, I can blow you up! Yes, it is basically fan + battery matching, but 36 fans total adds up to power to have 272 horsepower, capable of generating 430 pounds of thrust! Such "Giants" of course can make you fly, so ArcaBoard can fly very well, with the help of the attitude control system, it can hover 30 cm above street level, or to cruise speeds of up to 20-kilometer, battery life up to 6 minutes-a little small right? Blame human battery tech tree Ah ~ why Arca enough Space on the basis of the basic package, also adds an additional battery pack available, two piece, you can let you fly for 35 minutes.

As for the price--I have said before this is ready for local, right? Well, I was relieved, you should have a plan: price is $ 20000! Note that this is the basic package price, if you are jealous, 35 minutes, and the extended battery pack requires you to spend $ 4500!
