The 2010 time has passed and we miss it. It puts us in a world that was unimaginable in the past, and shortens the resolution of “generational differences” from 30 years to 10 years.

This may be the last generation we can understand.

The 2010s witnessed the breakthrough of social networks and e-commerce to mobilize hundreds of billions of dollars of wealth, and also made us feel that smart phones are important to life. Complete remodeling. It is not just those ridiculous consumer electronics that are leveraging the entire business society and changing the human lifestyle in the 2010s, but also those “giant little levers”, those hidden between the squares of products, and those invisible in the air Unable to touch, those commonplace and subtle things.

Push: Humans recognise the world

“Typhoon Liqima has caused deaths in the whole province.”

On August 12th, the Tencent Video App pushed the emergency department of Shandong Province about Typhoon “Lichma” In the news, due to editorial errors, a handful of salt was sprinkled on the wounds of the people in the disaster area.

Push (push), let the message break through the space and time constraints, and present it at the fastest speed in In front of every visitor.

The emergence of search engines has greatly improved the efficiency of our information acquisition, and push to make information available From active to passive.

As early as 2003, Blackberry launched the Push Email feature for users, which was also the first time for email Become a method of instant messaging. But in 2010s, push officially entered the era of rapid development.

In the three years from 2010 to 2013, there were two “formal” changes in push : From a single content, to the ability to customize different content by user category; from plain text to images.

In 2016, with the addition of machine algorithms, push inOn the basis of being able to complete the predecessors, they have the expected capabilities. It does a better job of analyzing users and guessing more precisely what users want to see. After this stage, the push became what we are now familiar with, and the click-through rate of the push also broke out after this stage.

As Zhang Xiaolong said, “The size of the world of a person was measured by footsteps, but now it is It is determined by the breadth of the information he has obtained. “
The appearance of

push allows users to obtain information more efficiently, which means that it can be used in a limited time Within, find out that this world is more different. The cost of measuring the world is lower.

But this is not necessarily a good thing, as the difference between foraging and feeding.

In order to enhance user stickiness, in order to enhance the stickiness of users, they often only do what they like, so that Users are immersed in the sweet area, and the content they are exposed to is getting narrower and narrower, thus further confining users to “information cocoon rooms” without knowing it.

Push may be the biggest editing option ever, Although the algorithm dominates the setting of topics, it is gradually eroding human curiosity and curiosity. From the utopia where everyone was the creator, the Internet has transformed into a live entertainment room where everyone is a consumer.

In the network age, there is actually no information overload, only filtering fails.

LTE: A Beautiful New World of Internet Services

At the beginning of the 20th century, a series of “Internet survival contests” caused heated discussions in China, one participated The challenging Beijing 18-year-old Guo Guopeng, after 26 hours of hard work, finally announced that he was out of the game because he was too hungry.

This is unthinkable today. A take-away brother will be delivered to your door at three meals a day. You do n’t have to go to the street to wait for a car and wait for you downstairs. The goods from all over the country will come to you the next day.

In fact, as early as the 2G and 3G era, the prototype of mobile Internet services It’s already It can be calculated in KB of network speed and feature machine performance, let these Internet services are just available, but the experience is hard to say.

Change came quietly 10 years ago.

iPhone puts the Internet in everyone’s pocket, and at the same time, called LTE (Long Term (Evolution) wireless network standards are gradually replacing 3G. LTE is the first batch of 4G standards recognized by the International Telecommunication Union and the only mainstream 4G standard.

Faster networks and smart phones, the chemical reaction between the two has opened the mobile Internet Golden Decade .

Now 1.1 million national-level applications WeChat and the world’s largest instant messaging application WhatsApp are all born At this time, and a global social revolution, it quickly replaced text messaging and opened an era of “everyone online.”

The payment wars of WeChat and Alipay later directly promoted the popularity of mobile payment in China. The small two-dimensional code connects almost all consumption scenarios and clears the last obstacle for the explosion of mobile Internet services.

Almost all offline service entrances have been moved to the lineThis has provided everyone with the convenience at their fingertips within 24 hours. Our life is gradually bound to various mobile Internet services, which is difficult to separate.

In addition to moving offline services online, the 4G era has also reshaped the field of online content services , Subscriptions are made into the mainstream business model, books, music, games, movies and television have become digital products for online subscription.

The popularity of mobile payment makes software subscriptions more convenient. Compared to buyout systems, version updates also Become flexible and subscribe to an irreversible trend.

The subscription system has also changed the relationship between users and digital content. We no longer have the “ownership of digital products” “There are only rights to use for a period of time.

Mobile Internet services with 4G and smart phones Reshape the industrial chain of each industry from the basic level of business, and also make everyone’s lifestyle completely changed.

SAML , OpenID, OAuth : Revolution of Internet Services

In May 2006, Brad Fitzpatrick, the father of the Russian social networking site LiveJournal, completed the formulation of the Yadis agreement and began Use it to implement a blog login system.

Yadis is Yet Another Distributed Identity System ” Another distributed identity authentication system ” Abbreviation for Its the sloppyness of the name and Linux (Linux Is Not UniX) can compete. Soon after Yadis was released < / span> , I got it < span class = "ql-size-12 ql-author-5781440"> Supported by Facebook-led manufacturers . Seeing to become the mainstream of the world , Yadis took the opportunity to change its name to OpenID that everyone (and not necessarily) is familiar with later.
The presence of

OpenID solves the problem of no SAML in the public domain. SAML Yes by SSTC 4 years ago Introduced the single sign-on framework (SSO) of the enterprise intranet, employees can use a variety of internal systems with one login, without having to repeatedly enter user names and passwords.

But the Internet needs an open authentication system that supports users worldwide- < / p>

OpenID!

After half a year, engineer Blaine Cook is developing T witter OpenID was implemented with a new requirement: users can use twitter to log in to websites to play games, but they cannot be issued automatically after unlocking the level T witter celebration. In short, an authorization mechanism is missing. So he released a draft OAuth in conjunction with DeWitt Clinton from Google.

In the next few years, OAuth gradually completed the replacement of OpenID. With the release of OAuth 2.0 (RFC 6749) in October 2012, it became the de facto standard.

Everyone knows the following story, based on OAuth 2.0 “ Weibo login ” , ” WeChat login “< / span> and so on throughout the 21st century.

” XX Sign in “ button replaces the password box, allowing users to start using various Internet services in just a few clicks. “ XX “ What is the abacus? To figure this out, we have to start with the nature of social platforms.

The social platform is an ideal virtual community that does not need to solve the problem of production materials.

Everyone can imagine that there is such a wealthy village that the villagers need to worry about spending money and stay in the village every day Going around just to enjoy life. The neighbors and neighbors know each other and exchange in the village square from dawn to dusk. But is it happy? Obviously not. What else needs to be done to make villagers happy? Investment promotion. The shopping mall next to the square was built, and the villagers happily bought and bought; the playground and school in the east of the village stand side by side, and the children are fascinated; …

The parking space in QQ space and stealing food by Renren.com are still in the memory of many people , Douban’s Alpha City has just ended a few years. NewbornSocial platforms will always make some self-built entertainment facilities, but the needs of users are endless. Therefore, the investment promotion of social platforms started with a login button.

The appearance of the WeChat mini-program makes the jump unnecessary, and it can be done with a single click, even adding a little It is expected that the group relationship will also be bound in one click, and the threshold for multi-person online interaction is set.

The point of the applet is not ” Go and run out ” , but ” When you come, use it “ . The aunt in the square may not know how to play Douyin, but she must know that you can give the dancers a love by tapping into the Bean Plaza Dance Mini Program.

In the past ten years, the number of Internet users in China has increased from 384 million to 854 million; 3 million to nearly 10 million. The Internet has changed from an addiction virus to a life-saving medicine.

Social platforms may not have thought that it is their login button that allows consumers on the Internet With service providersWithout perception, a remarkable scale expansion was completed.

Two-dimensional code: Mobile payment sweeps China

At the beginning of 2015, WeChat launched a red envelope campaign. During the Spring Festival, WeChat Pay was tied to 200 million banks. card.

This inadvertent work, which Jack Ma called “Pearl Harbor sneak attack”, became China Mobile’s payment Turnaround: People who did n’t even use WeChat have shaken red envelopes, and the social way of red envelopes to celebrate the New Year has allowed people to have a balance in their “small change” accounts, and there is a reason to spend these small changes.

Wechat and Alipay, the two giants used social and online shopping methods to let people tie their bank cards to their mobile phones, but the real Unicom merchants and user phones All roadside stalls will be displayed-QR code.

As a product of the 1990s, two-dimensional code is just a kind of two-dimensional barcode. It A more accurate name is a QR code (Quick Respond Code).

Two-dimensional codes were first used in automobile manufacturers to track parts. Because two-dimensional codes are quite fault-tolerant, Strong, the pattern can be read by the machine when the area is 7% -30% damaged, so it is also widely used in the transportation outer box.

For a long time, two-dimensional codes have not been separated from industrial uses until smart phones and WeChat Rising in China, this graphic, which has been invented for 20 years, has become an object that everyone can “scan”.

In the past, no matter whether it was an outlet, a self-service bank, or a POS machine, there must be a fixed physical outlet or The device can deposit and withdraw and pay, while QR code payment requires only a piece of paper.

For a time, Alipay and WeChat started making QR codes for merchants on the streets and alleys for free. And various Internet services such as taxis and takeaways have become catalysts for the popularity of mobile payments with almost crazy cash subsidies.

Two-dimensional codes are by no means the best way to experience mobile payments. One-touch payment of NFC It’s fast, but it’s this unbelievable two-dimensional graphic that, at the lowest cost, becomes a bridge between the two parties paying. As in “Three Body”Like the fearsome weapon “two-way foil”, it has implemented a dimensionality reduction blow on a large number of mobile payment technologies.

Credit cards have not been able to move out of a few consumer places in China for more than 20 years. Relying on mobile payment on the QR code, it has swept through every corner of China in just two years, becoming a universal payment tool almost as cash.

Computational photography: reshaping images and mobile terminals < / h3>

On April 13, 2019, a debate about “true and fake moon” became Weibo Hot topic on the web.

Whether the landscape captured by the mobile phone camera is consistent with the image generated by the light falling on the retina at this moment into the eyes, many people first started thinking about this problem And realize the existence of “Computational Photography”.

Turn on the front camera of the mobile phone, when the person in the picture is automatically peeled, whitened, thin face, large At the moment, these functions brought by AI computing have now become standard on smartphones, and they have subtly changed our perception of traditional photography.

From the moment you open the camera app, the calculation has been running for a moment, when the iPhone XR was released There was a slogan “Terafillion operations, every moment” to highlight the powerful performance of its A12 bionic chip. In this context, the A12 processor as the core of the calculation is more important than the CMOS sensor.

The rapid development of computational photography is inseparable from the benchmarking role of Google Pixel series phones. In the three years from 2016 to 2018, when the mainstream mobile phones on the market have developed to three cameras, the Pixel has used a single camera for three consecutive generations to counter this trend, and behind it is Google ’s neural network and algorithm models. span> , the latest Pixel 4 can already adjust the exposure and shadow preview in real time .

Computing photography has now become a battleground for smartphone fighters. The iPhone 11 Pro ’s Deep Fusion, Pixel 4 Astronomy ModeX30 Pro’s AI-enhanced moon mode, not to mention the super night scene and auto HDR that everyone has.

Pros and cons of equipment and optical design are still important to photography today, but under the same hardware conditions Next, through the combination of algorithms and computing power, computational photography has achieved cornering overtaking of traditional photography.

When automatic HDR replaces the post-stack, automatic AI reduces the frequency of opening the retouching software again and again, calculates Photography has lowered the threshold for taking pictures. Make “Handy Shot” truly available, more and more people can enjoy taking pictures. It is said that this is convenient for the photographer and improves the film production rate. It is said that this is reshaping the video and mobile terminal.

When the annual optical upgrade of traditional cameras has become commonplace, these smartphones Relying on the most advanced computing capabilities on the mobile end, leveraging photography, a world with nearly 200 years of history.
