Summary again in rice noodle Festival ends successfully millet NET electric

Can determine is that the April 8 to millet, like 11.11 to Ali, has been a title sponsor and a fixed holiday.

OtterBox iPad Mini Case

From 2012 of first session rice section began, millet currently has continuous four years in April 8 this days big activities, and on like double 11 when Beijing East, and suning and GOME not let Ali a designed beauty as, rice section day millet of old head Huawei, and charm family, and cool sent also are collective out make field to has, again plus day also while is HTC M9+ and beauty figure phone of launches, so can said day of lively degree has far beyond has many people of expected.

But both in terms of sales, amount, or from influence, crowding the screen includes micro-blogging, media attention and records broken, apparently Huawei and Meizu cut millet Wu's idea was not successful, but would sure get a large slice of this rice noodle Festival revellers "curtain", are worth it.

Why millet made?

However, millet today released several times the usual inventory, required before appointment or rush to buy users there is not authentic, but held this view as well may be there, then why millet opposite day?

For millet for, continued do rice section of primary reasons on is it need regularly maintain brand and fans groups between of relationship, but weekday in of has has has regularly promotions and snapped up of "General" means, so its must to took out a more has ceremony sex of concept, to create out a more tall Shang, even is total Grand Carnival of feel, and rice section is for of came into being of product.

In addition, millet, rice, and online e-commerce market promotion is actually almost makes sense, because you can take the opportunity of more positive exposure, this approach is not as hard ads allows consumers to watch out for, and most wind up momentum through the media. And in the end, in addition to the direct product sold outside rice for rice blast is extremely effective.

Behind the Festival, you should look at the millet system

Rice noodle Festival last year after millet networks in terms of scale business enterprises, China has become the third, but it has not been much noticed, the main reason is that when phone is still the driving force, that is to say, at that time still gives the impression that the millet millet network mobile phones online stores, rather than a real, mature e-commerce companies.

But to has today, you is not can ignored this is has, because in millet Sun out of transcripts in, phone (including flat), and TV (including box) and router this old three pieces although still occupy theme, but is has no longer alone beauty, intelligent hardware and accessories of sales results also dazzling exception, even just released didn't long of millet socket also became has sales highest of single products--including Lei in yesterday held of launches Shang also again said, millet network positioning of is vertical electric business, It contains with millet of main business millet phone (including flat), and millet TV (including box), and millet router, also while contains with millet ecological chain in the of more than 20 more species products, this on both sides with composition has millet of ecological chain, but millet of ecological not closed of, future at least also to do 100 paragraph products, here side of products is open of, non-exclusive, not exclusive, purpose is build a full open of platform.

This that is, millet network of target may just domestic maximum of line Shang intelligent equipment electric business, it also aimed at has became can provides large strong needs and high price life supplies of more category sale website--in millet teamed up has beauty of, and proposed has future to investment full 100 home enterprise of Grand target zhihou, its electric business business of imagine space has has has very ample of extended surface. Let alone the rice noodle Festival, almost overwhelmingly is winning some gadgets – light bulbs, mouse pads, scales, they bring millet's brand identity is strong, then at the most representative sales of more than 240,000 more than one power strip, which should be taken so that the number of people in traditional industries not sweet not sleep.

And just a few categories, and millet is a brand, it got so much traffic and conversion rates, do not bring festivals like alijingdong to be overwhelming advertising, this in itself is already one of the great wonders of the e-commerce industry.

Rice noodle Festival is also the same as double, has its back side

Rice section is a miracle, but it while is side mirror, both foreign singing has millet of cattle broke, is also refraction out has millet current many of problem where, for example many products stock of grey mark also displayed has bound millet of is not marketing, and still is capacity, and from must degree Shang for, this is millet of electric business business currently still cannot further to mass of reasons one of.

Also has is problem is logistics, millet currently although has established up has 12 a warehouse Center, also has Shun Feng, and as wind up, third party Express help its escort to last a km, but like warehouse this heavy assets, apparently not millet at and focuses on of, and this caused of directly effect is, now even is Shanghai Pudong of some regional are no open millet TV of purchase permission, and in future millet into of electric commodity class increasingly more zhihou, can wants to see millet of pressure also will further increases.

Also, most important of is this times rice section of orders data reflect out, 2.12 million Taiwan phone only sold has 1.717 billion, is equal to average each Taiwan only more than 800 more Yuan, this also basic can determine sales of at least seven or eight into are is red meters phone, this directly reflect has small Mi Li home of this of 1999, also has yearning for high-end of 2299 price of products, in now of sales momentum does not hot, overall also is large relies on low-end products for shipping main of embarrassing--this is apparently is fatal of, Gross margin because of its bulk and size are fastened to this, it may bring more and more pressure will make great cracked the myth of millet, now millet is trying to brand image and diverse hardware layout work, however, which have not been provided to the millet is a substantial, genuine competitiveness based on the ecological significance and the moat.

Smart device step by step how to save our hearing

Text/Zhao Shanjun

Since the birth of mankind, has been trying to battle with disease and aging. And partial loss of function of the body, human effort, there are two ideas: "repair or replace". Unfortunately, the "fix" does not apply to all cases, limbs cannot grow new limbs, hearing loss, ears not recycled ... ... Then look for "alternative" became the only viable way.

In a pirate movie, we can see a vicious pirate captain face have wood feet. In contemporary society, crutches, wheelchairs and even blade prosthetic common, vision's friends on the nose also the optical lenses of the glasses, hearing loss friends also wore a hearing aid, there are artificial joints, artificial heart, lung, and kidney. Even the latest movies of the Polytechnic Institute in imagining the implanted chip.

We should be grateful, technological and medical advances, "alternative" technology is more and more mature. Author at the hearing healthcare industry, volunteer Science Popularization of the current "smart devices" only counted in application of the evolutionary history of the industry.

Smart first step: click sounds

Hearing aids, you may have the impression. A few decades ago, has a white-haired old man ears headphones hanging in front of the long line, shirt pocket has a radio box. This is now rarely used "analogue hearing aids", simply, is a linear amplifier, sound amplifier. Users than the original hearing, "amplified sound" clearly intelligent

Second step smart: linear amplification

Later, found that the loss of hearing loss at different frequencies are not the same, bad linear amplifiers for analog circuits, digital hearing aids have emerged based on the DSP chip. After rigorous listening tests, based on different frequencies to different amount of compensation, making linear amplification of the sound more suitable for users of hearing aids.

Third step smart: noise reduction and scene recognition

Later, found a problem hearing aids: wear hearing aids do feel there is noise? Through establishing sound data models, through the identification of environmental noise, "noise reduction" programs, but users in different demand scenario for effective voice is not the same. Do? Have emerged through a smart phone's location to determine scenarios, and the hearing aid sound handler handler to automatically switch between different scenes.

Smart device step by step how to save our hearing?

I like happy hearing aids, Oticon

Fourth step smart: made for iPhone

The use of mobile phones, is also important for the hearing impaired, call wearing a hearing aid, always a little inconvenience. In the latest hearing aids, already have a 2.4Ghz Bluetooth connection between the phone and hearing aid.

Smart device step by step how to save our hearing?

Fifth step smart: technology integration

Going to have a very small hearing aids? Hearing aids can do not damage easily? Hearing aids can have batteries with long? Hearing aids can be based on Chinese language policy? Ted Baker note 3 covers

Smaller and smaller chips, making small size and power consumption, and good performance;

Nano-dustproof and waterproof coating makes use of a hearing aid is not easily broken;

Chinese voice models for data analysis, program for Chinese language processing.

Ultimately, the hearing aid as a smart device, not on a technology by leaps and bounds, but chip, power supply, language processing, microphone technology, such as the development of an integrated.

 

Reconstruction of listening with smart device? Ted Baker Note 3 Case

Said hearing aids, we think if a person's hearing loss hearing AIDS cannot function do? Such as severe and extremely severe in patients with otitis media in patients with nerve deafness, they cannot use an existing hearing aid.

I would say that cochlear implant was the first in human history: real artificial organs? It can replace human functions, high Biger.

Basic principle is a coil implanted under the skin and the electrode, electrode directly stimulate the auditory nerve obtained hearing. Worn speech processor on the ears, between the head and the coil implanted under the skin to "trans-skin communication" signal transmission.

Smart device step by step how to save our hearing?

Relates to implanted under the skin, then use the material and human exclusion does not appear. For example: titanium alloy, ceramics, silicone. In addition to the material, is the process of production, chip subcutaneous fluids seeping, just does not work (from the point, tech movies directly in the ear implants don't make sense). None of this is the highest level of technical requirements, but do these techniques, it is difficult.

For otitis media and otitis externa in patients with abnormal inner ear function and need not do cochlear implants, hearing AIDS cannot, do? Still there is a way.

Smart device step by step how to save our hearing?

This is the vibrant SoundBridge technique. Principle, it is probably in the cochlea of the inner ear, there's a metal vibrator, instead of three tiny bones in the middle ear for sound transmission.

Smart device step by step how to save our hearing?

This is bone-anchored hearing aid BAHA technology. General principle is embedded in the skull of a titanium alloy nail, outside is the processor, by skull vibration transmission.

Smart device step by step how to save our hearing?

This is the Sophono bone-anchored hearing aids, unlike BAHA was, bare nails or skin without something else, implants, implant, processor and implants by "trans-skin communication" approach.

Smart devices can also replace what organ?

Above, is hearing medical science, and in the last few years, "artificial vision" technology is already in clinical trials. Retinal prosthesis technology, intraocular implant chip help the blind regain visual approach. Pity is that current technology can only help the user with a sense of light and contour, cannot yet be completely reconstructed vision.

Smart device step by step how to save our hearing?

To sum up, intelligent artificial organs, is coming towards us. Materials technology, development of power technology, chip technology, communication technology, mankind in the near future to achieve "handicapped rehabilitation, blind sight, deaf fucong. "The real development of smart devices, maybe just need to improve on existing equipment, intelligent, and more importantly," demand "," technology "," expanding discipline integration "come true.

Hammer 1 I began to understand the products we were

"Editor's note" the writer is former Hammer technology product manager, is now Doodle nails co-founder and product manager, and this article is his the voice of experience: a product manager how to get started? Reason appears to be very simple, and product managers, which was enough to resonate with many details. At any time, even if you don't have a clue, you can do not just brush your circle of friends.

Hammer 1, I began to understand the products we were

Written on the front:

Give a couple of friends some product manager for advice on how to get started, combined with several years of work experience before, under the share. But both need attention:

1, my methods are probably suitable for small teams, and does not necessarily apply to a rigorous process and meticulous division of a big company. To ask the latter to do, talk to your leader, why study if nobody has brought this company would be too wide of the mark, and is replaced as soon as possible.

2, product manager, the most important is the ability to think independently. Saying "listen, hear the dark", I think the product manager can not hear, they want to and have the ability to reason and facts to convince others (not on lip shaking smart to convince others). So remember, don't make me (and anyone else says) when the Guide step by step.

Following is the text:

1. exercise understanding of their products

Beginners just getting started will be the range of prototype tools and stacks of cases of kidnapping, mind is someone in fancy features and their dog blind programme but do not know their products, head is full of other people's things.

PM like usual dialogue with others is generally:

A (the boss): do you think the four tabs here reasonable and unreasonable?

P (PM): reasonable, of course, beauty, reviews, micro-credit, do so. It is decreed.

A: we function on the page layout that reliable or not?

P: no problem. This style is the most common, interact is guaranteed to be the most popular. Unique tonal design is a popular international design concept of Minimal.

A: well, that our features are required, please?

P: competing products, these features have been, we are not bad, right?

A:......

Understanding of their products can be divided into several aspects:

Understanding of the company, and investors with the boss about

Understanding of the users, with the company's positioning and market conditions

Understanding of product positioning, related to user's original intention of positioning and product launches

Understanding of the company's research and development capabilities, including design, development and operational capabilities

Understanding of the situation in other sectors, including departments doing and all State

...

In short, you make every judgement must be based on a wide range of understanding, rather than competing products, to understand the factors, understanding of the market fragmented. Avoid belly black –

Hammer 1, I began to understand the products we were

Only such, dang designer made you not satisfaction of manuscript Shi you can said "you of this style may for young, but we of target user is business people", and not said "you this enough atmosphere, no feel Ah"; Dang you requirements engineers modified a looks not important of BUG Shi can said "follow-up operation sector plans has good times large activities, to Shi flow will moments soared, you this BUG will zoom 10 times times, so is dangerous", and not said "important not heavy were it not for you engineers set of, Is a product manager, you come "; when you're debating whether to add a feature with the boss can say," I think such functionality is an important complement to do coincide with next version ", rather than" competing products do we can't fall, whether it works or not. "

How to exercise that, in fact, is a laborious and brain thing, you have to constantly communicate with the boss, communicate with colleagues, chat with user, to do research, and doing a lot of thinking and summarizing. You have to have a dictionary, recorded explanations of everything related to the product under your name, can read at any time whenever you want to query.

This dictionary can be written in the heart, can be organized into notes. The eyes of others, it may not matter, is not the mouth "trends in human-computer interaction" closed "three-dimensional design language" which can be used to hold a forcing term. But not this dictionary, every step you take is a pit, walked away when coming back to fill in, it was too late.

2. analysis and judgement ability

If the understanding of the product is the first step, the second step is how to make reliable judgments based on your understanding. GUCCI case for iphone 6 plus

Oddly enough, a lot of PM in addition to others, which is to do user research, or only the boss is from. But a lot of things simpler, and as long as there is life, there is reasoning based, clearly is more reliable.

For example.

Android MIUI do when localized, is adding the lunar calendar as one of the main characteristics of, also widely acclaimed. T1 calendar when we consider this issue: how add does not add to the lunar calendar?

Plus, the entire interface is very full, looks ugly; without it, users will need to see the lunar calendar of sorts.

It is common for a calendar interface:

Hammer 1, I began to understand the products we were

For research for the PM, just do a survey questionnaire, the bigger the better, look at where users; user positioning is on the high end for PM user or enthusiast, may make a switch option, open, not closed.

But indeed can reasoning a step further: why do users need the lunar calendar?

About scene: before and after the Chinese new year; lunar calendar holidays; his birthday with family and friends. This basically covers the needs of all users.

That's easy, we just display the lunar calendar when is Chinese new year and holidays? For a birthday, we can provide the settings, users and friends birthday display the lunar calendar every year.

This is a T1 calendar interface:

Hammer 1, I began to understand the products we were

This is to a large extent, prevent the embarrassing interface always displays the lunar calendar, but also to meet the needs of most users of the lunar calendar. This common sense can figure out soon right? Without complicated questionnaire? Without the complexity of product design, right?

You might say, this is a shake quick needs analysis, and was a small feature. Let me give you an example.

Doodle nail before we discuss the most basic functions and interface, not reference O2O tools popular in the market are what functions, which a few tabs, how publishing. We do the analysis of users at a time.

GUCCI case for iphone 6 plus

User questionnaire to analysis does not depend on what to do. You in the questionnaire asked "what kind of user you are," "nail care more about what do you do? "They are difficult to answer clearly. If you give specific options, what could be induced to answer possible, final conclusions often fail to explain the problem. GUCCI iPhone 6+ Case

Our analysis is that from common sense nail users using our products are what kinds of scenarios:

Style 1, has wanted to do for the user.

2, users who want to do nail art, but not a certain style.

3, uncertain, do not do it just to look at the user.

For each user, to this demand is certainly different:

1, did you want to do the style or something like that style.

2, see you have a nice style.

3, look what you have done enough to attract her nail place.

Demand for these three, we want to provide functionality is different:

1, style offers customized services based on user, search and filtering capabilities.

2, excellent/top recommended; search and filter functions.

3, topic boutique/top recommended.

So, when users see our products for the first time, we need to provide the functions at a glance: feature, featured, search/filtering and customization.

We judged that the product has just launched, the 3rd user most certainly, the 2nd user will gradually rise, 1th users is high-end, advanced user, appeared much later. On the function of primary and secondary are clearly.

Last first edition products, recommended and we decided to focus in on the topic, the search function is the second online features and customization will be a future version of the feature. Interface layout and typography, also feature clear priorities, so knowing.

Looking at the end result, out of the interface seems to be pretty much the same. But because every feature, from a development perspective, consumes energy, will affect the experience from a user perspective, if it is thinking of, a little difference, some of the optional features will be diametrically the wrong decisions.

In fact, all these things are common sense can judge. You said I'm not a woman, understand nails Editor, but you go to Taobao, Jingdong, right? User ideas when shopping or can imagine, right? When you have after the initial judgment, user research the meaning reflected: it was as a means of verification. But it cannot be used as source of demand.

To sum up, the product manager before making any decisions, to do three little words:

Speak the truth.

How to cultivate the ability? Is not difficult. Is to ask why in everyday life.

This community needs around three laps the car park entrance, why design? The UNIQLO's door, a glance is all underwear, displaying what is the reason? Coffee shop downstairs usually do not have many customers, but actually lasted five years before closing, their revenue and expenditure balance?

Much is the same, every day want to understand something, that really encountered difficult problems, you might want to know further, than the others can count on. Continue to look at other people's products, but not the fur, but to think about business models, to interaction details, to the visual style of cause, doing what makes sense.

3. to ensure good communication and presentation skills.

If products are fully understood, have a clear judgement on various issues, the next step is to take these their understanding and judgment make full Exchange and communication with colleagues.

In fact, it is not difficult, or communication skills, is said to have frequently mentioned the EQ on the one hand, how powerless you are facilitating you to complete tasks, coordinate the work of all not so boring; the other is to make every communication is efficient, not a waste of time.

For the former, my suggestions are:

1, always know he is product manager, but not the Manager, not aggressive;

2, with well-grounded facts to convince people rather than "boss's decision," "with you it doesn't matter anyway" this fucking;

3, others are in trouble should not say, "I don't care, it's your thing", take the initiative to understand his difficulties, and do our best to help solving unsolvable options together;

4, product item there is contradiction between any of my colleagues in the group, to take the initiative to coordinate on the sidelines watching;

5, feel free to let colleagues know the progress on each product line, allow us to master;

6, the user's feedback to well known colleagues, let everyone have a sense of achievement, feel they do have value.

For the latter, my suggestions are:

1, every discussion, whether it is a pair of a chat or a meeting, clearly the purpose of plan;

2, describes the problem clearly, want to say, and don't run;

3, each forming conclusions, do not discuss to discuss has to feel very full, no conclusion is nonsense;

4, do not give anything to other people to decide themselves ready for further options and recommendations;

5, record each time the process and conclusion of the discussion, you can always check out;

Ability to learn the fastest way of communication is not recited from a book, or note me to copy these small, but find someone you feel very comfortable, very good people, learning of his advantage.

4. product responsibility

Responsibility seems to be the most easy to some, but I faced a lot of good PM feel shame.

I particularly enjoy @ Chi Jianqiang's bottom line: product managers have been the most important ability is to make the right things happen.

1-3 you do what I say, but that's just doing "the right thing" whether they have occurred, but to test your sense of responsibility.

Engineers for the project in the middle line, when you were downstairs eating popcorn in the cinema, or quietly beside him? In the designer with the boss because programmes make stiff when you're waiting for them to shake hands, and is actively looking for bosses or talk to a designer project as soon as possible? Business colleagues for a emergency activities when you demand less actual features, you are a "to do" sent away or is under serious discussion with her is there any other way I can manage with that?

Yes, strictly speaking, you're working with company contracts, you can't be forced to work overtime; your job is product, not solutions to help others; you are not the owner, the company is not up to you to fill in.

But a good product manager, is responsible for any product-related services. Any product line should be properly solved by you, any help should be given to the products concerned.

Choices in this, determine your product manager is mediocre or excellent.

5. concerning the use of tools.

Tool at the end says, is because the actual sense of the product manager, and do not have to master too much prototyping tools, interactive drawing tools or drawing tools.

No matter what tool is well known and is currently doing service. Is that sentence just now, why would you use it? Do it now do things helpful to you?

Many start-up teams just beginning, began to build the massive Feature/Bug of recording and processing platform with extremely complex requirements document describes rules, Axure, as essential mind mapping tool. Not increase efficiency, but caused a lot of problems.

Just like MBA is not suitable for entrepreneurs, complex processes will be a serious drag on the operation of the small and medium sized companies. I usually use Keynote, Sketch the tool that can completely overwrite the 90% demand for design work; product development needs Trello or windmill for recording and processing, simple, and easy to use.

Remember a can: just think on hand tools easy to use, efficient, and that there is no need to replace on the tall. In addition to acting, no other meaning.

6. the wide-ranging

The last time, "" a friend asked me, he often argued with the designers, he always felt that painting on the layout problem, but could not say where is the problem, what should I do. I said it was simple, intuitive if you have a problem, it may have made some basic mistakes, you have to learn more knowledge of typography, and more to understand common typography, that following the controversy sure has clout.

As product manager, understand the basics of some of the other posts are very useful. This will not only ensure good communication, can also help you in considering the needs, design idea. This is a good addition, and certainly not okay.

To see what they were looking at books and find some basis of a look or you can know that fast-food kind of article. So that others won't say, forced blind every day this guy will want some ideas, draw some dubious prototype, do not pick up energy programmes.

However, although the product manager to learn is very important, but I think with a kick-ass master, can you really be a kick-ass product manager.

Push a machine intelligence data why not

Push a machine intelligence data, why not?

To test data will want to review the data behind the technological, commercial and social dimensions. Developing maturity, technical dimensions go far, commercial dimensions have developed but not fully mature, the social dimension of development is the worst.

So while the data has been talked about for a long time, but gave birth to several areas such as search, data, and other areas not visible benefit from the data. Most of the time, people still think that there is definitely gold, but need to be more patient. This article try to to the characteristic of the data itself to mining, to forecast future trends.

The depth and breadth of data

If the data corresponds to the mass of data, then it is a very vague concept, equivalent to become synonyms for information, apparently also would be difficult to answer exactly what information this problem.

In order to advance the thinking at this time typically need to categorize. If the perspective of time and space as the most fundamental, the first thing to distinguish is the depth and breadth of data. From the perspective of time data is full of history, from the perspective of spatial data traces global events. The former can be seen as a kind of depth, which can be seen as a kind of breadth, different scenes to the depth and breadth of focus is different.

For some vertical industries, such as health care, greater data depth is more important, all of history can be found on the data, people can better cognitive and optimized for their industry.

Where the community is concerned, many width is more important, specific to a scene we had scraps of news, but when this information is enough, broad enough scope, it is possible to describe the picture of relative time. Examples of Google predict infectious disease often rely on this kind of breadth.

Application development trends that determine how much data is at a depth where important companies such organizations need to be the subject, difficulty was how to cross data ownership boundaries. For hospitals, the treatment of cases and sharing of data is all good, but if there is only one hospital did, that this is more a hospital may be the harm posed by privacy back.

Breadth in important places, although search companies can also benefit from such areas, but can fully benefit from the institutions is a matter of Government. Wider data, which describe the subject more, and if the description of society as a whole, it should obviously be the primary responsibility of the society will benefit. It is a matter of common sense, and the doctor won't eat his doctor give people the medicine I'm good but almost. Sometimes CCTV broadcast the Baidu make movement of people during the Spring Festival, also happens to be this thing that the problem from the side. This map of the movement of people can make the map helped far without Government help.

Simple summary is: both depth and breadth of data requirements are different, the former need more detailed, quality of data sources which will contribute to this high, but at the time of application will face issues such as paid return wrong. Tend to describe the data as a whole, and have the ability to collect or handle data tend to be individual, individual return is not easy to get a clear embodiment in the Ascension of the whole.

So the bottleneck in the development of the data is not technology, but behind the establishment of distribution needs. This relationship is not suitable, the data stays on the island, each organization has its own what, and named it "big data". In order to rationalize this relationship going back to a classic problem, "public land" could establish.

Data Commons vision

Big data is a bit like the Commons, an argument in economics is very famous is the tragedy of the Commons. United States economic history cites an example what is the tragedy of the Commons is pretty straightforward:

"..... The proposition of economic reasoning to explain the ownership and sharing of outputs (or fixed share equally) how "free riders". To illustrate this point, consider sharing ownership of land, and produced 100 bushels of corn about 10 workers, spent an average of 10 bushels of corn. Imagine a worker begins to be lazy and labor effort in half, resulting in decreased output 5 bushels. Because of the sharing arrangements, consumption of slackers and other workers, is now 9.5 bushels. Although his efforts have fallen 50%, but his consumption only fell by 5%. Slackers are take other labor ride...... "

Very well the human nature behind it, even if we can collaborate to create more wealth, from which individuals can share more, but obvious personal inclinations in the group then we are working less but more. This is the prisoner's dilemma is the same.

Based on real world not see thorough methods to resolve this problem at the moment, only relies on some basic recognition of distribution, such as: descent now before natural selection, but a bit digital wealth but have the potential to solve this problem.

Based on the bits of data and is the biggest difference in kind, data is not what you take away what I don't have, and the rapid decline in the price of the hardware, open source and data access tools, essentially for free. These are added together, make it possible to data.

Very interesting question here is, if you care about the things I get are larger in absolute terms, the data form, the more likely the Commons. Because if there is a Data Commons, everyone (enterprises) will not gain much, but if you care more about me than you, that data public building will be more than a lot of obstacles, because Commons is designed to let people stand on to the beginning of the same competition.

Big data problems, data on the use of technical problems, but are social and economic problems in the data source, which is more difficult, so data does not depend on technology in the use of socio-economic development depends on the pace of change. In a limited area, such as search, e-commerce, cloud computing, technology has been fully developed, who benefit is paid at the moment is to put the data into the main problems in the process of data.

Data is the way to go?

Internal development force of the data is the data value bigger, in fact, this is also a network effect, this internal dynamic macro-data ownership of only two trends:

A is now mobile-like, everyone has their own private data sources, then begin the cut-throat competition, and end up with a live, which you can also reach the ultimate goal of data.

Other is United in the competition began, construction of above data Commons.

As mentioned earlier industry data and data of the whole society is so different nature study separately.

For industry data, and frank cooperation among competitors unless there is a special character, it is unlikely. In this case the simplest way is to introduce a third-party.

Each carrier holds almost all Internet users, for example, mobile data, but for the operators to cooperate openly with each other, and put the data together to create some sort of value, this is tough. If there are third parties involved, make a profit distribution scheme that is possible.

If this can be achieved, the only critical point is the appropriate business model can go beyond data processing costs. Under this point must be stressed is that the value of the data density is sparse, many things of great value but not necessarily worth doing, video sites make money a key reason is that bandwidth and storage costs are higher, and bad business model for large data, the situation may be worse than the video site. Cost to dig how to is less than the proceeds of mining mining is valuable.

These problems in data may be the problem is not too large, general industry data the value of density is going to be larger, and because relatively vertical, total limit after all. So big data applications is likely to develop.

But on social data, which in many cases is a problem. We all know that the comprehensiveness of the sample is worth more than the amount of data, but if you are the only means to ensure the samples are comprehensive, that must have all the data it makes sense to get something done.

Social data, there are two applications, an enterprise can handle such as Google, you belong to the social level, it is difficult to separate people who belong to an enterprise such as the smart city activity data. The above data is required to support the Commons.

From data of perspective view, now has two species data store form: a is Google such of enterprise has whole social a cross section Shang of all data, this should is species exception, and data will limited in public information; a is is was fragmented of various and people behavior related of data, like shopping related of in electric business, and people related of in social network and IM, line Xia service related of is in O2O enterprise, railway related of in 12306,. Google that has the data, but does not have human behavior, so Google the company equivalent to a cross section of data with society as a whole. While all other companies only have a vertical data.

If the attempt to rely on business to do this kind of data, in the former will do O2O has invested 20 billion class action because it will complete the data, the latter would have wanted to do as a business social networking, social network wants to do this sort of thing happening. Similar story can also occur at the terminals, the ultimate goal of all of these actions are a company to take care of all these things, but this is not possible, the impossible not only for economic reasons.

Data cannot be opened, it can only be done on the fragmented data thinks big data, big data.

So this kind of data can ever build the Commons problem, and wants to set up a Data Commons, then at least solve the problem of who is going to do, is the source of inspiration in two key: first this is not a profit-making organization; second it can get the support of many businesses. Because the data privacy are involved, so compared to open source it must also have a more clear definition of the data using rules.

Summary

In a practical way to solve before all and use data, big data applications should also be local. Application involves many parts of society because of its depth coordination with each other, so the process can be very lengthy.

This interesting things is that large data directly promotes the development of intelligent machines, and machine intelligence may affect speed is much faster than the data itself. Marcelo Burlon iPhone 6+

Fresh water salt and lithium ion batteries available security level higher

  As we all know, lithium-ion battery has small size, large storage capacity and long life and so on. This battery has many forms, such as applications in smart phones, laptops, cameras and different consumer devices, such as smart watches, are also used in pacemakers and other medical equipment, or even military and aviation equipment, and so on.

  In October, researchers from Cambridge University said they have created a new lithium battery-oxygen or air, the battery even when charged after 2000, the effective rate is still as high as 90%. Researchers say the batteries to be used on commercial equipment, may take around 10 years time.

Fresh water, salt and lithium-ion batteries available: security level higher

  Just last week, from United States Army Research Laboratory researchers said they have developed a "salt water" lithium-ion batteries, not only provides traditional lithium-ion battery with the same life expectancy and efficiency, and does not require the use of sulfuric acid, lead and cadmium and other toxic chemicals, harmful to the environment.

  Making less toxic and harm low batteries on the environment and the impact of the consumer in the long run. In April this year, Tesla announced that it will open up a new business unit – Tesla Energy and battery solutions to provide consumers with family, Enterprise, which also raised the prospect of energy storage intense discussion of the fast-changing market.

  It is understood that, for now, Tesla family of battery solutions orders have exceeded 100,000, from this point of view, toxic water and salt of lithium-ion batteries should be a good thing. The new battery can be applied to requirements in kW or megawatt-level areas, such as electric vehicles and even a grid storage system.

  Of course, this maximum may be in aircraft, naval vessels or spacecraft and difficult fuel cell battery safety and toxicity is very high.

Fresh water, salt and lithium-ion batteries available: security level higher

  Researchers believe that using a high concentration of aqueous electrolyte can change chemical reactions within the battery and anode electrodes to create a thin layer of protective film. This protective layer is to maintain the battery hold-down, and implementation and is currently a key point of the same high-performance lithium-ion batteries. Therefore, this is a remarkable breakthrough. Incipio iPhone 6 Case

  According to the United States Army Research Laboratory says Edward Shaffer, Director of the energy and power sector, this discovery may lead to safer chemicals and environmentally friendly batteries. For example, he said, the application of new types of batteries will include soldiers carry equipment, it can also be used to reduce the energy footprint of the storage device, such as submarines and other space-constrained devices.

  In addition, the research team from the University of Maryland, also participated in the study, the team consists of chemical and Biomolecular Engineering, Chunsheng Wang, an associate professor in the Department of leadership, they said, the work to upgrade the battery voltage/power 1 time, this means researchers in the water battery is a big step forward in the history of. Results of their research will be published in the journal Science.
