Burst! Huawei’s 5G is “cut off” again, how to defend against technological bullying?

editor — Wed, 23 Jun 2021 16:20:08 +0000

Today, the Swedish court upheld an injunction prohibiting Huawei from selling 5G equipment in Sweden. Soon afterwards, Huawei issued a statement in response to express its regret and believed that this court decision was not the final one. It is studying further legal remedies and looking forward to dialogue with relevant Swedish parties to seek solutions. The editor believes that Huawei spares no effort to fight for related rights. In addition to not wanting to miss the Swedish market, it is more important to avoid destroying its hopes of a comeback in the European market and triggering a knock-on effect. Therefore, this matter must still be handled properly. The verdict has a knock-on effect, Ericsson is full of “survival desire” Crucially, the above-mentioned Swedish agency did not provide any facts and evidence of Huawei’s security issues during the public trial, and clearly described it when submitting documents to the court. There was no evidence that Huawei’s equipment and software had technical vulnerabilities. This is really a bit confusing, a bit out of nothing, and it feels like a thief shouts and catches the thief. In fact, this matter dates back to October last year when the Swedish Postal and Telecommunications Administration banned Huawei or ZTE from supplying 5G equipment to Swedish mobile companies, including participating in 5G spectrum auctions. The equipment that is still in use must be replaced by early 2025. In response, Huawei also filed an appeal. Obviously, the Swedish court rejected Huawei’s appeal this time and upheld the “Huawei 5G ban.” Therefore, the editor also believes that the decision of the Swiss side may cause a knock-on effect and have many subsequent effects. Previously, the attitudes of many European countries towards Huawei’s 5G need not be repeated. Romania is the latest country to actually ban Huawei from participating in the construction. However, because of the use of the Danish intelligence agency by the United States, the situation seems to be turning for the better. Italy’s recent reversal of its attitude shows signs of lifting the ban on Huawei, which may trigger other European countries to follow suit. Perhaps a country like Italy, which is a bit “sorrowful”, is very good at standing in teams and turning back. It will always lean on the winner’s side, and Sweden should learn more from it. After all, from the perspective of the country’s direct interests, rejecting Huawei will undoubtedly leave Sweden’s own 5G development behind. The UK has also suffered before, not only the lagging network construction, but this is still a continuous matter, to bear the additional cost increase in the next 10 years. It also has a negative impact on the political and economic aspects of the country. Generally speaking, under the political and diplomatic pressure of the United States, although European governments are reluctant, they have to bow their heads and prosecute themselves. They have to deal with between the two major powers and block Chinese companies from participating in 5G construction. From the perspective of corporate interests, there is no practical benefit at all. Huawei’s 5G is blocked out, and local Ericsson should logically be pleased. However, Ericsson had a high-profile support for Huawei. Obviously, Ericsson believes that the Chinese market is much more promising than the Swedish market, and it has shown a great desire to survive. After all, banning Huawei will greatly increase the negative impact of Swedish companies, including Ericsson. Although China is not the most important market for Ericsson, in the domestic 5G network bidding construction last year, Ericsson also showed signs of being marginalized, but at least about 10% of its revenue comes from China. For this reason, a month ago, Ericsson also issued a warning that its business in the 5G market in China is expected to shrink substantially. Looking forward to China’s “legitimate defense”, Catching a Duck on Shelves and Technological Bullying On the other hand, the outside world is also observing the response and actions of the Ministry of Commerce of China, especially whether it will offer a list of unreliable entities to counter it. The editor checked the relevant regulations and found that foreign entities included in the list of unreliable entities may be restricted or prohibited from engaging in China-related import and export activities, and their investment in China may be restricted or prohibited depending on the circumstances. After all, the Ministry of Commerce only announced the “Regulations on the List of Unreliable Entities” in September last year, and this seems to be the same. In order to deal with the irrationality and arrogance of the West, it is of course a legitimate defense. However, one trades another. After Huawei’s 5G equipment and technology are continuously suppressed by Europe and the United States, Nokia, Ericsson, and Samsung will naturally further erode the European market. Even second-tier 5G network equipment suppliers such as Samsung Electronics will be able to do so. Entering the European continent and signing a contract with British Vodafone is really trying to catch the ducks on the shelves. The naked economic and technological bullying in the West continues. Last Thursday, the U.S. Federal Communications Commission (FCC) unanimously voted to ban the approval of equipment from five Chinese companies in the U.S. communications network on the grounds of “national security threats.” The companies involved include Huawei, ZTE, and Hytera. , Hikvision and Dahua. The editor believes that the U.S. has become accustomed to constantly generalizing the concept of “national security” and abusing national power to suppress specific countries and companies without any evidence. This is also the United States once again openly denying the principles of market economy, freedom and democracy that it has always advertised. In any case, for Ericsson’s operations in China, regardless of whether it is countered by the Ministry of Commerce, it will ultimately pass the Chinese market and consumers. Relevant Swedish institutions should formulate objective, uniform, and verifiable cyber security standards based on basic facts. This is the perfect solution. (Editor in charge: Andy) Finish

Experts talk about making good use of algorithms: using social ethics to guide technological development

editor — Tue, 22 Jun 2021 03:22:12 +0000

Data map. Image source: Unsplash Beijing News (Reporter Xiao Longping) On June 18, the Intelligent Media Research Center of the School of Journalism and Communication of Tsinghua University and the Xinjing Think Tank jointly held an online forum on “Algorithms Make Good Use of Intelligent Humanities: Multidisciplinary Integration of Intelligent Information”. Experts and scholars from the School of Journalism and Communication of Tsinghua University, the School of Journalism and Communication of Beijing Normal University, the School of Journalism of Fudan University, the School of Philosophy of Renmin University of China, the School of Journalism and Communication of China Communication University, and the School of Communication of Shenzhen University, discuss the value creation and social development of algorithm technology The positive significance of the discussion. The algorithm of “Top of the Storm” has opened up people’s cognition, psychology and thinking paths In recent years, the term “algorithm” has appeared in the public eye with an unprecedented frequency. Some algorithm-related events have aroused attention and heated discussions in our country and even the world, and algorithms have become a focus of attention on the “tip of the storm”. However, from the academic discussion of mathematics to computer programming languages, algorithms cannot be regarded as a new concept. According to Yu Guoming, former dean of the School of Journalism and Communication of Beijing Normal University and a Changjiang scholar, the reason why “algorithms” are suddenly hot is because the rapid development of information dissemination technology has created an “algorithmic” digital economy and a new society of information dissemination. As the foundation of the digital economy, algorithms are moving from “behind the scenes” to “foreground”. Jiang Qiaolei, associate professor of the School of Journalism and Communication of Tsinghua University and deputy director of the Intelligent Media Research Center, believes that algorithm technology may not only be used as a tool to greatly enhance and change the depth and breadth of the influence of past media effects, but also open up people’s recognition. Knowledge, psychology and thinking path. For example, some scholars studying memory have found that after using smart media, people’s memory method has changed from the original content of specific information to the path of memory to obtain information, that is, how to find this information. That is, people no longer accurately remember the specific content of the information, but remember where the information content can be found. Once needed, the specific content of the information is retrieved through the search engine, and the algorithm facilitates the channel of information acquisition. Facing ethical dilemmas and improving algorithm transparency While the algorithm brings convenience to human life, it also exposes some contradictions between technology and humans, technology and humanities, including contradictions in values and ethical dilemmas. Zhang Taofu, executive dean of the School of Journalism at Fudan University and a Changjiang scholar, said that the biggest contradiction at present seems to be magnified by technology. What is the biggest contradiction? The contradiction between the finiteness of our cognition and the overproduction and overload of information. In the technological age, people’s cognitive ability has not been doubled, but the amount of information possessed has increased exponentially. So, “How can I find the content I need in a limited time with such a large amount of information? The subject itself cannot solve it. It must provide a solution for us through technology and algorithms,” Zhang Taofu said. At the same time, worries about the “information cocoon room” followed one after another. American scholar Cass R. Sunstein put forward the concept of “information cocoon room” in a political context. In our country, this concept has been misunderstood and abused. For example, there is a view that continuous algorithmic recommendation will keep users in a similar information field created by personal interests for a long time, forming a “cocoon room”, and rejecting other reasonable opinions from intruding. So, does the “information cocoon room” really exist? Chen Changfeng, executive vice dean and professor of the School of Journalism and Communication of Tsinghua University, believes that if people live in a pure environment where only homogeneous information pushed by algorithms and only obtain one type of information, it is possible to form a “cocoon house.” But in fact, the information environment of our era is diverse and rich, and content with inconsistent views cannot be avoided. The current diverse information environment is a paradox formed by the “information cocoon room”. Data map. Image source: Unsplash The “information cocoon room” is just a worry. Chen Changfeng introduced that the information aggregation platform can enhance the diversity of information by optimizing the technical model of the algorithm. This provides the conditions for individuals to obtain richer information, and also stimulates the user’s subjective initiative to become a “active audience”. It can be seen that media literacy education is also a way to resolve the misunderstanding of the “cocoon room”. Jiang Qiaolei agreed that when the transparency of the algorithm is increased and a wider range of users can participate in it, it will naturally reduce the worry about the algorithm. Make good use of algorithms and guide technological development with social ethics In the past historical and cultural context, the ethics of algorithm technology has not been included in the scope of thinking. Jiang Qiaolei pointed out that in a society where people are the main body, the legal level of regulation and the expectations of moral concepts have been fully and maturely discussed, but the communication ethics and media ethics with algorithms as the main body need to be re-examined: Some legal norms and existing moral concepts, adapt to and accept it. According to Professor Zhang Xiao, deputy dean and professor of the School of Philosophy, Renmin University of China, our use of algorithms should be limited, because artificial intelligence built by algorithms is actually limited intelligence, not human intelligence. At the same time, algorithms are just tools, and all the responsibilities cannot be shifted to algorithms. A limited agent constructed by algorithms should not bear any moral responsibility, because at the ethical level, it has no autonomy, self-discipline, self-control, and self-awareness, and it is not a moral subject. Zhang Xiao believes that the entire evaluation and ethical review of the values in the design and operation of the algorithm will help to think about the ethical issues that may be involved in the design, operation and application of the algorithm, and the ethical issues that may arise from these ethical issues. Some of the moral consequences of this, and then let the public have a certain sensitivity in advance. Zhang Taofu said that technology is now in the front, people in the middle, and regulations in the back. Therefore, it is necessary to strengthen the regulation of algorithms and other technologies, and only the mechanism generation can guide the behavior of the public. Earlier, the European Union’s “Ethical Guidelines for Trusted Artificial Intelligence” proposed the principle of making good use of algorithms. The future of intelligent algorithms is to understand ethical algorithms. In the algorithm development process, a cooperative “algorithm development mechanism” is adopted, that is, stakeholders are involved in the development of algorithms, so as to form an algorithm governance model in which stakeholders participate in decision-making. Professor Chao Naipeng, dean and professor of the School of Communication of Shenzhen University, believes that algorithms involving multiple stakeholders can effectively manage ethical issues such as the so-called “black box” of algorithms to a certain extent. The cultivation of users’ digital literacy is a way to solve algorithm concerns. After users understand the operating logic of the technology itself, they can get rid of the “black box” from the epistemological perspective. Chang Jiang, a distinguished professor of the School of Communication of Shenzhen University and the executive director of the Center for Media Convergence and International Communication, mentioned, “Even if some things can never be made transparent, But I can realize what the “black” logic is.” Qiu Junqian, an associate professor at the School of Journalism and Communication of Communication University of China, emphasized that finding and understanding the boundary objects in the intelligent ecology, planning and predicting the technical logic and ethical logic behind them will help open the “black box” and allow technology to better serve people. “We don’t need to worry about it, simply and rudely hit the algorithm to the bottom, and blame it for the original sin.” Chen Changfeng said that technology helps the public to be surrounded by sufficient information and multi-faceted choices to pursue their own preferences and gain more. To communicate more, use new technology with a positive attitude, and let it serve mankind. Serving social groups with algorithmic information is the proper meaning of science and technology. Today, Toutiao has launched the “Toutiao Searching for People”, and Douyin has launched the “Sunflower Project” to ensure that minors go online. The Internet and other platforms are also following closely. Combine algorithm technology with social development to serve the public. “We need to implement well-intentioned advocacy and rational criticism into the effective development of algorithms, and use social demands to promote technological innovation. This is the ultimate goal of making good use of algorithms,” said Chao Naipeng. Reporter: Xiao Longping Editor: Zhang Xiaoyuan Proofreading: Li Lijun

Build the most technological 618 JD Cloud releases the top ten technology application trends of 618 for the first time

editor — Thu, 17 Jun 2021 17:14:12 +0000

On June 15th, a media salon with the theme of “Decoding JD 618: JD Cloud Releases Top Ten Technology Application Trends” was held in JD. This is also the first time that JD Group has integrated cloud, retail, and logistics multi-party 618 technical teams to jointly decode JD 618. Technical connotation. At the event site, JD Retail unveiled the 31.2 days inventory turnover, the mystery behind this world-class figure, and JD Logistics “relay” shared how to achieve minute-level delivery to more than 200 cities across the country through an integrated supply chain. The process shows the whole chain process of goods from retail to logistics, and finally to consumers. At the same time, as the technical cornerstone of JD 618, JD Cloud has fully demonstrated the rock-solid technical support for JD 618 in the face of traffic peaks and through “training as a battle, fighting for training”. It is worth mentioning that after years of experience in the most complex e-commerce scenarios, JD Cloud released the top ten technology application trends to the industry for the first time, showing JD’s four dimensions of people, goods, markets, and digital infrastructure. Latest exploration.

Intelligent supply chain decision-making, 31.2 days is a world-class number

Among the ten major technology application trends, JD.com’s intelligent supply chain decision-making has created a world-class record for JD.com’s “inventory turnover days reduced to 31.2 days” through intelligent operation, warehouse network optimization, omni-channel contract performance, and C2M reverse customization. According to Liu Xiaoen, vice president of JD.com and head of JD’s retail smart supply chain Y business department, behind JD’s 31.2-day turnaround is faced with great challenges, which are mainly derived from four aspects: massive amounts of goods, complex warehousing and distribution. Online, online and offline multi-scenario retail model, and matching with the supply and demand of a large number of upstream suppliers. Costco, a global retail giant known for its operational efficiency, has its latest inventory turnover days of 30.9 days, but it manages only a few thousand SKUs, while JD.com has millions of SKUs and more than 1000 warehouses, with a turnover of 31.2 days in all categories. Under the self-operated mode, it is already at the world’s leading level.

Looking to the future, the goal is to be technology-based, to achieve continuous optimization of supply chain efficiency and experience, and to create a more accurate, faster and better intelligent supply chain. At present, JD.com has achieved a world-class turnover of 31.2 days. It is changing from a global leader to the leader of “no man’s land”. In the future, it will become an explorer of technological boundaries. Through continuous technological breakthroughs, JD.com will drive the intelligentization of JD.com. The technological change of the social supply chain supports the implementation of the national “new infrastructure” strategy.

Total force ‘dispatched’ many technological solutions to prevent Covid-19

Trọng Đạt — Tue, 11 May 2021 11:30:08 +0000

The saving of ‘epidemiological landmarks’ with QR codes, tracing suspected infected persons by Bluezone and medical declaration on NCOVI will create a set of tools for early detection, effective localization and limit the spread of the epidemic. .
Using technology against Covid-19

With dozens of Covid-19 positive cases being discovered every day, many solutions such as localization, tracing of suspected infected people, vaccination, community immunization, … have been deployed to limit the spread of the disease. However, unlike other pandemics, Covid-19 is showing that this is not just a common pandemic. With many variations and outbreaks, the prevention of Covid-19 is a long battle and requires the participation of the whole society. This fact shows that non-traditional anti-epidemic solutions are needed. Anti-epidemic technology is the most optimal choice today for the society to function normally. People harvest agricultural products in the epidemic heart in Hai Duong. Photo: Trong Dat To meet the urgent requirements of epidemic prevention and control, the Ministry of Information and Communications has issued the document “Instructions on the use of Covid-19 support solutions to prevent, combat and trace in the community”. Accordingly, in order to combat epidemics with technology, localities need to combine many different solutions. These solutions included the implementation of the installation of Bluezone (the application of warning for close contact with suspected Covid-19) and NCOVI (voluntary medical declaration management system). Localities also need to deploy the system to record people coming and going to public places through QR code scanning and epidemic prevention map system. For places with airports and border gates, these localities need to make electronic medical declaration for people entering. What is the effectiveness of anti-epidemic technology by technology? According to experts, technology solutions such as Bluezone applications can only achieve high efficiency if they are used by more than 60% of the population. Recognition of the developer shows that, as of March 2021, more than 30 million people used Bluezone applications. Considering the actual implementation efficiency, during the 2nd Covid-19 outbreak (July 25, 2020) in Hai Duong, with the proportion of people who installed Bluezone being 27%, 1,035 was identified in this locality. F1, F2. Many recommendations have been made by authorities about people should install Bluezone application to receive warnings in case of contact with suspected Covid-19. Photo: Trong Dat In the second outbreak on January 27, 2021 in Hai Duong, the rate of installing Bluezone applications was 43% of the total population of the province. As a result, the system has traced 1,993 F1 and F2 cases. It is noteworthy that by doing this, the health agency found 17 positive cases outside the list of traditional epidemiological investigations. With the successes and experiences gained in Hai Duong, Bluezone is considered as the most effective measure for effective zoning, helping to maintain the status of an isolated house, the whole society can still operate normally. With NCOVI application, as of February 3, 2021, the number of NCOVI applications installed was 7.8 million. The number of medical declaration records for the entire population is 18 million, the number of updated health monitoring records is 52.95 million, the number of scan records of QR code is 7.25 million. Medical declarations are basic input so that health agencies can keep informed about the health situation of each citizen. The large collection of medical manifest data also makes it possible for authorities to immediately detect a large-scale Covid-19 outbreak. Citizens are encouraged to make electronic medical declarations at least 1 time per day. Recently, Vietnam is using another solution, which is to check in to save epidemiological landmarks with QR codes. With this measure, people need to scan QR codes to check in every time they go to public places. In the event that a person is determined positive for Covid-19, the authorities will base on the history of scanning the QR code of the person to filter out the “epidemiological landmarks” that the patient has joined or went to. for a period of 3 days before onset of illness. Those who have arrived at the “epidemiological milestones” during the time the patient checked in will be listed for the investigator to trace, from which the F1s will be identified. Workers at the aluminum mine in Lam Dong perform check-in by QR code upon arrival at the workplace. According to the representative of Bkav – Bluezone application development unit, the measure of checking in public places helps to quickly track outbreak places such as restaurants and markets. In addition, the regular check-in by QR code on Bluezone also helps to increase the efficiency of contact recognition. Storing “epidemiological landmarks” by QR code, tracing suspected infected persons by Bluezone and medical declaration on NCOVI will form a set of tools to help early detection, effective localization and limit the spread of the epidemic. This is how Make in Vietnam digital technologies creep and solve problems in life.

Scientific and technological forces prop up the “protective umbrella” for the “world’s first ancient pear orchard” in Gaolan

China News Service, Lanzhou, April 16th (Shi Jingjing, Ai Qinglong, Gaozhan) In mid-April, spring is in full swing. Located in the “world’s first ancient pear garden” in Gaolan County, Lanzhou City, the pear blossoms are in full bloom like white snow, and there is no one. The aircraft is patrolling at high altitude, and the “red ribbon” is hung on the tall and tall old trees to repel insects. This means that Gaolan has entered a new stage in its use of high-tech precision protection of ancient trees.

“The World’s First Ancient Pear Orchard” is located in Shichuan Town, Gaolan County. The contiguous pear orchard covers an area of more than 10,000 mu. There are more than 9,000 ancient pear trees that are more than 100 years old, and the oldest pear trees are more than 400 years old. It was entered into the “Guinness Book of World Records” in 2013.

According to Yang Weiming, director of the Shichuan Ancient Pear Orchard Management Committee, since this year, the Ancient Pear Orchard Conservation Center has cooperated with the Orchard Station of the Lanzhou Agricultural Research Center to set up two test demonstration sites in the core area of the Ancient Pear Orchard to carry out the use of drones to control pests and diseases. The main content of the experiment and demonstration work is anti-domination, biological bacterial fertilizer to improve the soil, biological control of pear borer and peach borer, and “belly connection” of ancient pear trees.

“Previously, the prevention and control of tree diseases and insect pests was a manual operation, which was time-consuming and manpower. Now, drones are used to spray drugs, and ultra-fine mist sprayed on the leaves at high altitude, covering a wide area, reducing artificial leakage and re-spraying, and effectively improving the prevention and control of insect pests. Efficiency.” Yang Weiming said.

At the same time, compared with the traditional way of spraying pesticides, the newly introduced “red ribbon” for insect control this year has also been recognized by the public.

Lu Xidong is the owner of a local farmhouse. There are more than 100 old trees in the ecological garden. The small pear borer on the tree may seem inconspicuous, but in fact it is a huge hazard and is likely to cause outbreaks of pests and diseases. Lv Xidong used to prevent insects on tree trunks and hired workers to spray drugs from time to time. It would take 2 to 3 days for the smell to be released after the operation. However, the effect of repeated use of drugs was not satisfactory.

This spring, Lv Xidong’s courtyard took the lead in using the new biological prevention and control technology introduced and promoted by the Guliyuan Conservation Center. This “red ribbon”-shaped migratory strip is environmentally friendly, efficient, and does not pollute the environment. As long as each pear tree is hung with 5 mitochondrial strips, the scent of the strips can be used to prevent the males on the tree from finding the females, and “lost in the direction of love” to reduce the females to lay eggs. Prevent and control pear worms throughout the year, and preserve flowers and fruits.

“A century-old tree not only has ecological value, but also confers cultural value.” Yang Weiming said that in the future, Shichuan Ancient Pear Garden will continue to explore drone control, green plant diseases and insect pests prevention and control experiments and demonstration work, scientific management and protection of ancient pear trees , To hold up a green “protective umbrella” for the century-old pear tree.
