Robot hounds enforcing social distancing in parks

The Singapore government recently announced that it will start deploying a yellow and black robot dog Spot developed by Boston Dynamics in a local park to remind pedestrians to keep a safe distance and help control the spread of the new coronavirus.

Although people have mixed opinions about the appearance of robot dogs, some people think this is an innovation that is beneficial to the epidemic, and some people have not been able to accept the sudden emergence of “beasts” in the park.

But it is undeniable that various robots do play a great role in reducing the number of people gathering and working during the epidemic, and the situation of the epidemic has also contributed to the production and application of some robots.

MIT: For every additional robot in American manufacturing, it replaces 3.3 workers

Recently, a study released by the Massachusetts Institute of Technology and Boston University showed that from 1990 to 2007, every 1,000 American workers increased by 1 robot, the national employment ratio fell by 0.2%, and the wages of workers decreased by 0.42%.

This means that for every additional robot in US manufacturing, an average of 3.3 workers will be replaced.

The above study, titled “Robots and Jobs: Evidence from US Labor Markets,” was completed in collaboration between Daron Acemoglu, a professor of economics at MIT, and Pascual Restrepo, an assistant professor at Boston University. The research paper was published in the Journal of Political Economy.

“Airpods Studio”?

Recently, there are a lot of rumors about Apple’s upcoming high-end headphones. This headset may have detection functions similar to AirPods and AirPods Pro. People will stop playing music when they take off the headphones.

At present, this headset is tentatively named AirPods Studio (inaccurate, named according to similar products of Beats). It may have in-ear detection functions similar to AirPods and AirPods Pro. According to 9to5Mac, people familiar with Apple ’s related product plans are cited because It is a head-mounted, it detects the neck.

“Studio” is the name of the previous Beats headphones “Studio” is the name of the previous Beats headphones
In AirPods and AirPods Pro, the purpose of ear detection is to automatically stop playing music when the headset is removed. The rumored AirPods Studio will have a similar sensor to detect whether the headset is worn on the head or neck. When the headset is worn on the head, it can start playing content. When in the neck, the sensor can pause the music. The other sensor will detect the audio channels of the left and right ears, which means that if the headphones are worn wrong, they can also be detected.

In addition, AirPods Studio is paired with a Mac or iOS device, which will open the custom equalizer settings for the low, medium and high frequency adjustment function, that is, with which device, the sound performance may be different.

Apple exposes new iMessage features

The patent application documents recently published by the US Patent and Trademark Office (PTO) show that Apple may make major updates to the instant messaging software iMessages that comes with iOS, iPadOS, and MacOS systems, including re-editing messages that users have sent.

Many people may have experienced such awkward situations, such as misspelling important information, or we misspelled the name of the recipient, and so on. However, this situation may soon become the past, at least for iMessage users on Apple iPhone, iPad and Mac devices.

The patent application document states: “Current messaging applications have many shortcomings and limitations. For example, their capabilities are limited in: confirming messages, editing previously sent messages, expressing what users are trying to communicate, displaying private messages, Synchronize content viewing between users, merge handwriting input, and quickly locate content in message transcripts, etc. ”

Currently, there is no application that allows users to re-edit text messages after sending them. If iMessage will soon get this feature, it will be the first long-awaited application for most people.

New spam on your iPhone

I believe the majority of iPhone users have been harassed by iMessage spam?

Not only is iMessage, spam text messages in the past two years seem to have a variety of strange ways to enter your iPhone, harassing you in all directions without dead ends. Following iMessage, mail and calendar, a new way of harassment has recently been discovered—album.

Many people are annoyed by the spam harassment information, but there is no way, so they have to endure it. In addition, a question for more people is: How do these spam messages appear in my calendar and albums?

This has to start with iMessage, Apple’s official instant messaging tool. You can understand this tool as a network SMS. To put it bluntly, you can use iMessage to send messages to your good friends using mobile data network or even WiFi, and there is no need to consume phone bills. Sending ordinary SMS bubbles on iPhone is green, iMessage is blue.

After the birth of the smart phone, Apple’s iPhone has been occupying half of the country, and the huge number of users has also allowed scammers to see “unlimited business opportunities.”

Although iMessage seems to be of little use to us, scammers always like to use iMessage to send spam and gambling messages.

In recent years, the operation of spam has become even more messy, and now even the calendar can be used to send a variety of messages and can even fill your schedule.

So how does the calendar send you spam?

First, open the calendar, click the plus sign in the upper right corner, and the “New Schedule” interface will appear.
It doesn’t matter whether the above information is filled in or not. The key point is the “invited person” below. Click on it and the “Add Invited Person” interface will appear. At this point, you can enter your Apple ID or select someone in your address book to send the schedule to others.

The scammers took advantage of this feature, adding titles and remarks to the calendar’s schedule, and then entering your Apple ID in the invitee, which gave rise to the magic operation that the calendar can receive spam.

Similar techniques can also be applied to Apple’s photo album. The invitation to share the album will also be sent to the invitees at the same time. When the scammers edit the name of the album, they can start to harass you unreservedly. The most annoying thing is that you do n’t even know who sent you the invitation. The invitation will only display a random name, you can not trace the source.

So why do we receive such spam messages?

The most critical issue is information leakage. Although we have no evidence to prove that the fraudster has a lot of Apple ID to send spam messages, but remember the screenshot above?

There is no fixed format limit for entering the invitee position. That is to say, no matter what format your Apple ID is in the mailbox, even scammers can randomly input a bunch of mailboxes, or the blind cat may encounter dead mouse. And it doesn’t cost a penny.

Finally, how to deal with these annoying spam?

The best way is to turn them off.

IoT in China

Cargo ship “into” the Internet

“We are at a precise grasp of where the cargo ship is currently, what the speed is, where is the destination, the load situation and historical sailing data.” Zhu Guanghui, chairman of Jiangsu Wurun Shipbuilding Network Co., Ltd., introduced For canals and other routes, the AIS (Automatic Identification System) base station is installed on the shore every 20 to 30 kilometers to receive all kinds of data sent by cargo ships in real time.

In the control room of the headquarters of Wurun Shipbuilding Federation, the big data platform of the Internet of Ships, “The ship is coming”, is tracking and displaying key information such as the schedule, pallet and ship owner of various freight ships in real time through a huge electronic map. Combining satellite maps and real-time data, navigation and congestion of ships in waterways such as waterways, locks, and anchorages can be seen at a glance.

Problems such as asymmetric information, high empty load rate and low carrying efficiency have plagued the logistics industry for many years. The “smart ship search” of the Internet of Ships has effectively improved the logistics efficiency. Relying on real-time data, the ship can be empty before the last voyage is completed. The port and empty ship time and the destination port of the next voyage are used to make predictions to help users find the required ship in advance and bid farewell to the traditional “overcast sky” search.

High logistics costs have always been a problem that has plagued economic development. The relevant person in charge of the Comprehensive Planning Department of the Ministry of Transport said that “cost reduction has become the highlight of the structural reform on the supply side of the transportation industry.” To address the pain points of the logistics industry, such as difficulty in matching supply and demand, low transaction efficiency, and high costs, the Internet of Shipping Analyze and calculate to make the supply and demand of transportation capacity more accurate and efficient.

Relying on the ship networking platform, not only allows the cargo owner and the ship owner to negotiate directly, remove intermediate links and reduce logistics costs, but also realizes the full traceability of the cargo transportation trajectory and the visualization of the shipping ship transportation scenario, which better guarantees the authenticity of the transaction and restores the true supply chain.

Through the “Internet +”, logistics and water transportation is gradually bidding farewell to the traditional model of the millennium, showing new vitality. “We firmly believe that more technological applications and model innovations will advance the development of water transportation logistics to a higher quality. This will bring more vitality to the Chinese economy, provide new tools for governance innovation, and contribute to the optimization of global supply chains. “Zhou Xu said.

What has AI replaced?

Many AI startups are using AI technology to find demand. To put it bluntly, they do n’t know what they are going to do, because AI technology does not create jobs, it just updates the tools. Example 1: Once humans cultivated by hoe, then by livestock, and then by machinery, tools became more and more efficient, but no matter how the tools changed, the demand for crops did not change. Example 2: Once humans exchanged items for goods, and later used paper money, and then used credit cards and PayPal. Although tools became more and more convenient, the demand for commodity exchange never changed. Example 3: Now that human demand for data has created new jobs that label data, it has allowed many people with disabilities to have a better income. Therefore, work changes with changes in demand, and work remains unchanged when demand is constant. However, the tools used in the work will be updated. The real danger in the future is that it will not be replaced by AI workers in the industry, but by workers in the industry who rely on a single tool. Even if the tool you master is the most advanced AI, it is equally dangerous, and even more dangerous. Because researchers are constantly updating the tools they invent, the more advanced tools are often invested in more research and development, so the fastest update rate. Today’s most advanced technology is likely to be completely replaced by the method in a paper tomorrow.

How AI is changing the industry
Thirty years ago, computers were also regarded as an emerging industry, but now people have long realized that computers are actually a tool to update the efficiency of all industries. All industries now use computers, and everyone uses computers. There are indeed a group of human beings replaced, but it is not that computers replace humans, but humans who use computers replace humans without computer assistance. As described in the following intercept: Humans who do not use artificial intelligence will be replaced. Now people ’s concerns about “AI instead of work” are exactly the same as people ’s concerns about “computer instead of work” in the beginning of the Internet era. But the fact is that the situation at the beginning of the era of artificial intelligence is also exactly the same as the situation at the beginning of the Internet era: instead of artificial intelligence replacing humans, humans are using artificial intelligence to replace humans that do not. This panic is different from the past because too many irresponsible media propaganda made people mistakenly believe that the current AI is autonomous.

Lee Sedol vs Alpha The human-machine war

Between Lee Sedol and Alpha can be said to be the tipping point of artificial intelligence. The media all interpreted the human-machine war as “Human lost to the machine”. But Dr. Aja Huang, who originally developed the Alpha Go, has been a genius of Go since he was a child (who once won the college cup Go tournament). And then joined the team with experts in many fields such as neuroscience, philosophy, and computer. Everyone is familiar with the rules of Go, and how to design the Alpha Go (more straightforward, speech recognition, computer vision, Natural language processing is also good, those AI experts themselves are experts in a certain field). This is where humans lost to the machine. This is clearly that Lee Sedol, who does not use AI, is “bullyed” by a team using AI. Can’t help but think of the poor candidates who did not bring a computer in the college entrance examination. Although AI dominates the chess world, it still does not affect people’s hobby of Go, just as we know that airplanes and cars have exploded into humans, but there are still Olympic Games. Instead of replacing the industry, AI has brought better teachers to the industry (Afa dog teaching system)

AI and Art Although the media and training institutions keep moving, the titles “AI replaces illustrator” and “AI replaces doctor” are outraged in all industries. But it is the AI ​​technology that requires human control to generate pictures, create music, and transfer styles. Who will decide how to use the generated content at that time? Does it depend on the straight man’s aesthetic ability? Of course, it depends on the artist. To whom will these technologies developed by AI companies be sold in the future? Of course still an artist. Adobe’s software will be updated with more automatic tools every time (you can view the new features of AdobeMax Conference). Gradually including AI tools.

What if the pictures generated by the technology can perfectly meet the quality requirements in the future? This just means that artists no longer have to work hard to produce these AI-generated content, but can transfer their energy to other creative parts. Example: Current video editing requires creators to consume a lot of time to watch related videos, and now has AI automatic editing technology, which can allow creators to put time on the concept of the content, without having to mechanically repeat the viewing.

AI and medical, academic For this huge system of medical, AI can be empowered in many ways: virtual assistant, case analysis, medical imaging diagnosis, drug development, etc. Due to the inherent advantages of convolutional neural networks (CNN) for image processing, coupled with the support of data volume, AI has higher accuracy in medical imaging diagnosis. For example, the Chinese team published a paper in “cells”, saying that its main research and development of artificial intelligence (AI) tools for accurately diagnosing two major diseases of eye diseases and pneumonia, its overall accuracy reached 96.6%. But this is like the thermometer and MRI can accurately measure a certain index of the patient, but only improves the accuracy of a message. Do n’t forget that the doctor ’s job is much more than just looking at medical images. Diagnosis requires comprehensive judgment combined with many factors, as well as complex decisions such as prescribing medicine, surgery, and hospitalization. Look at how hard it is to train a qualified doctor to know that “AI replaces doctor” is really overhyped.

Don’t think that medical only imaging diagnosis but doctors who use AI are really different from doctors who do not use AI. We all know that this is an era of information explosion. There are countless papers published every year. No human can read all the literature in his lifetime to pick out the information that is useful for his research. I think everyone who does scientific research on this All have a deep experience. But if there is AI to help quickly read the relevant research from all the literature and improve the search efficiency, it will bring unprecedented help to the researchers’ work.

5G is not a gimmick!

5G is not a gimmick!

It will eventually realize the overall vision of “information is at your fingertips, everything is within reach”. At present, major countries around the world are seizing 5G commercial deployments, competing for the high ground of a new round of industrial chains, and the fierce competition between countries is not just for a “gimmick”. At the same time, we must dialectically see that the popularization and application of 5G is a gradual process, not an overnight one. Regarding whether the 5G era has arrived, we can’t make it clear in only a few words but should seek to establish a more systematic and objective perception.

What is the difference between 5G network and 4G network?

1) The speed has been greatly improved. The theoretical rate of the 5G network has reached 10G. Downloading a 1G movie can be done in a few seconds. When 5G is officially commercialized, the download rate of wireless access can reach about 1G, which is a qualitative improvement compared to the current 4G network.

2) Base stations are denser 4G uses base stations, which is what we usually call “iron towers”, and can achieve coverage in the range of several kilometers. The 5G network uses millimeter wave technology because the frequency is higher, so the coverage is small and the anti-interference ability is weak. Covering the same area, the number of 5G base stations will be dozens of times that of 4G base stations, and the dense networking of small base stations will become the mainstream in 5G (this will also bring high costs).

3) Larger-scale “antenna array” In a 4G network, each base station has a maximum of 8 antennas. 5G base stations use “antenna arrays”, with hundreds of antennas distributed in each array. 5G mobile phones will also adopt the antenna array method accordingly. The advantage of this is that it can provide better and better coverage, and provide users with new experiences such as 4K ultra-high definition.

What is the difference between 5G chips and ordinary chips? Answer: According to the equipment used, 5G chips are divided into base station equipment chips and mobile phone chips. Compared with ordinary chips, the most obvious difference of 5G chips is that it not only supports low-frequency bands below 6GHz but also extends to millimeter-wave bands from 26.5 to 300GHz, which is the biggest bright spot. It should be noted that the requirements of 5G chips for equipment and processes are very high

The advantages of the current 5G mobile phone: Under normal 5G network environment, the rate can generally reach more than 200Mbps, or even reach 1Gbps, and can experience the high speed of the 5G network first.

The disadvantages of current 5G mobile phones: mobile phone and network compatibility issues, heat dissipation and battery life issues (all currently being resolved), and the price is relatively expensive

In addition to mobile phones, what content does the layout of the 5G industry chain include?

1. Virtual reality, Internet of Vehicles, Internet of Things, unmanned driving and other emerging technologies;

2. Intelligent application of industry, medical treatment, transportation, etc .;

3. Cloud games;

In recent years, more and more smart technologies have been applied to automobiles. However, the requirements of intelligent technology for data communication support are quite high, especially in the field of autonomous vehicles. For example, the car is driving on the road, and it is necessary to avoid the road in parallel; if the network speed is not strong, the autopilot system reacts for 1second slower, the final result may be that the car is killed and killed … With the service capability of 1ms delay, the ubiquitous 5G network provided by the operator can provide a strong security guarantee for autonomous driving. Therefore, 5G is a prerequisite for autonomous driving. Products and solutions related to the 5G industry, such as industrial Internet, unmanned driving and Internet of Vehicles, are promising. With the development of 5G, it will definitely promote the development of the industrial Internet and accelerate industry intelligence. This is a general trend. After the intelligent interconnection of all things is realized, it is expected to truly subvert various industry scenarios.
