Lei Feng Network (search "Lei Feng Network" public concern) : When the Japanese softbank to buy ARM news has been exposed, the entire science and technology circle has been boiling, the two companies do not have too many related companies on the surface together. As for the reasons, judging from the initial capital operation to later guessing about artificial intelligence, it is still necessary to prove the truth in the end. This week, the invisible long-lived Kaixin.com suddenly exposed the news, the founder and CEO Cheng Bingyi left the company, and the transformational game Kaixin.com also went back to the A-share after going to the US market. After a while, the circle of friends set off a wave of reversal. Trend of thought ... more wonderful interpretation, please click the link below to read.
1. Japan's Softbank's acquisition of ARM is really related to artificial intelligence? 
Japan Softbank spent 23,400 million pounds to acquire British chip design company ARM.
Some media claimed that "Japan Softbank is trying to acquire ARM and artificial intelligence related" and said "As to why it is necessary to acquire ARM, we must start from the dream of artificial intelligence of Softbank." In recent years, Softbank has been active. To advance the development in the robotics field, they have launched Pepper humanoid robots and will continue to increase the competitiveness of the company's artificial intelligence industry."
So is the truth of the matter as the media say?
......
Tieliu believes that in the case of recent negative news, it is no different than advancing into artificial intelligence and releasing a favorable signal to the capital market. After all, “There is no money is absolutely impossibleâ€, and through some media and capital operation methods, Its own stock price is also very beneficial to Softbank.

2. Cheng Binghao: Happy for eight years
On July 22nd, Kaiping Chang, founder and CEO of Kaixin.com, issued a letter of resignation and announced that he had withdrawn from Kaixin.com and said goodbye to Kaixin.com and Kaixin.com.
In 2008, I and several of my colleagues from Sina founded Kaixin.com (Beijing Happy People Information Technology Co., Ltd.). I am leaving now (2016) for a total of eight years. This is my summary and farewell to my eight years.
In 2009, many people thought that Kaixin.com had the opportunity to become a super-internet company. But what made me paralyzed investors and employees was that Kaixin.com had started to decline in user activity since 2010, and finally transformed into a mobile game company. It is no longer a platform company. In 2015, Happy Company's profits were tens of millions. This is the crystallization of happy people's cleverness and struggle, but it is far from the “best possible†seen in 2009.
why?
......
On the tail of this 8 years, look at Cheng Bingzhao's own reflection.

3. Whether it is the decline of Kaixin.com, or Plato's ban, social operations without barriers are juggling.
The Kaixin.com network, which has faded from public view, became the news again because Cheng Bingyi resigned, and the intelligence bulletin for the game stated that he had signed the “Issuing Shares and Payment of Cash Purchase Assets Framework Agreement†with Kaixin.com, or 100% of Kaixin.com.
The author of this paper believes that whether it is Kaixin.com, Renren.com or Weibo, the surge of data again and again will not be successful, because all social operations that cannot build barriers are rogue.
When Kaixin.com defines the strategic path as a "explosion game," when Kaixin.com's UGC experience is far better than playing games, his fate is already doomed, because light games are almost certainly not a transfer cost. You will build a moat mode. You only have to bet on every game you launch. Of course we know it is almost impossible.
The author of this article analyzed everyone, happy, Weibo, and other communities, and summed up some of his views on UGC operations. For more exciting content, please click on the article to find out.

Depth gesture perception: not only simple human-computer interaction | depth
In a sense, human civilization is a process in which human beings continuously understand the world and themselves. Cognition refers to the whole process of collecting, filtering, processing, predicting output, and adjusting feedback of useful data—information. .
The meaning of in-depth situational awareness is “the perception of situational awareness, which is a human-machine intelligence that includes both human intelligence and machine intelligence (artificial intelligence)â€. It refers to the signifier + signifier, and refers to both things. Attributes (signifiers, sensations) are also related to the relationships between them (referring to the senses). They can both understand the sounds outside the strings and understand the meaning of the words.
A consensus concept regarding Situational Awareness (SA) is “the perception and understanding of the various components of the environment within a certain time and space, and then predict the subsequent changes of these componentsâ€.
In short, in-depth situational awareness is essentially a process in which many public opinions, such as change and invariance, one and many, autonomy and passiveness, are generated and resolved. Therefore, the system should not be a simple human-computer interaction but should be an autonomous process (including expectation, selection, prediction, control, even involving the emotional domain) throughout the human-machine environment system.

5, decrypt Microsoft HoloLens: the next generation computing platform in the glasses?
In January 2015, Microsoft released Hololens, its in-house developed holographic smart glasses, which are very different from the virtual reality glasses and augmented reality glasses on the market. They can identify the surrounding environment and the user's actions through See- Through the entire waveguide display program, to give users a holographic visual experience.
The Hololens hardware platform uses an Intel X86 32-bit processor. In conjunction with this processor, there is also a full-line processing unit (HPU) dedicated to holograms and ambient sensing. It features 2GB of RAM and 64GB of ROM, and supports Bluetooth and WiFi.
Hololens is equipped with a full operating system based on the Windows 10 system and named Windows Holographic.
Hololens integrates a depth camera and multiple sensors. After the CPU obtains the sensor data, Sensor fusion technology can be used to implement multiple interaction modes.
AR and MR are in line with the law of historical development. In the near future, they will certainly replace personal computers and smart phones and become the next generation of computing platforms. The layout of Microsoft and other giants in this field is bound to accelerate the arrival of this node.

6, 5G communication technology interpretation | beamforming how to add wings to 5G?
The transmitted electromagnetic signals are concentrated in one direction, and as long as the receiving antenna can be aligned in this direction, as many signals as possible can be received.
The traditional method of forming a beam using a single antenna requires turning the antenna to change the direction of the beam, which is clearly not possible on a mobile phone. Therefore, a practical beamforming scheme uses a smart antenna array.
The size of the antenna is determined by the wavelength of the electromagnetic signal. The electromagnetic wave wavelengths of WiFi and the current mobile phone band can reach more than ten centimeters. Therefore, it is difficult to integrate such a large antenna on a mobile phone. To solve this problem, we can combine beamforming and millimeter wave technology.
Beamforming can concentrate the signal energy in the direction of the receiving end, thereby improving spectrum utilization efficiency. Beamforming combined with millimeter-wave technology allows the communications system to have high bandwidth and support simultaneous communication for a large number of users, thus making the 5G system even more powerful.

7. After Pokemon Go bursts, what should be the ultimate experience of mobile AR?
The explosion of Pokemon GO has attracted everyone's attention. When analyzing the reasons for its success, the media and investors all believe that Nintendo's Pokemon, a powerful IP, has provided the global fan appeal, and the LBS technology used by AR is considered to be The threshold is low, easy to imitate.
So is the threshold of AR technology really low? What is the ultimate experience of mobile AR?
AR Technique Rating in Pokemon Go: ★
Pokemon Go LBS-based AR technology rating: ★
Pokemon Go's image tracking based AR technology rating: ★★★
Pokemon Go slam-based AR Technology Rating: ★★★★
The ultimate experience of integrating AR, LBS, image tracking and SLAM into one: ★★★★★
