Millions of people all over the world lose their lives every year because of sudden death, and about 80% of sudden deaths are sudden cardiac deaths.

According to the statistics of the National Cardiovascular Center, the number of sudden cardiac death in China is as high as 550,000 every year, and the proportion of young and middle-aged people has increased significantly.

According to CCTV reports, more than half of the sudden deaths are young and middle-aged people.

Sudden death is a fierce "killer" that threatens human health-people who seem to be in good health or stable condition at ordinary times suddenly die of natural diseases in an unexpected short time, which often makes people unexpected and unable to fight back.

At present, there is no unified standard for defining the time of sudden death, which is considered to be within 1 hour, 6 hours, 12 hours and 24 hours, while the definition of the World Health Organization (WHO) is that death occurs within 6 hours of onset. Because sudden death is sudden and unpredictable, many people especially want to know how to find the early signs of sudden death while worrying, so as to prevent and avoid the occurrence of sudden death.

In fact, there are precursors to sudden death, and these signals must be paid attention to! Find it as soon as possible, and you can’t ignore it!

Clinically, although sudden death happens suddenly, except in extreme cases, many "alarms" will be given to us before problems occur. People at high risk of cardiovascular and cerebrovascular diseases should pay special attention to the following abnormal manifestations (signs of sudden death) to prevent sudden death.

Sudden aggravation of chest tightness

If you suddenly feel chest tightness after exercise in the near future, rest for a while can relieve it. This phenomenon suggests that you may have coronary heart disease.

The sudden symptoms indicate that the atherosclerotic plaque in the coronary artery is still unstable and may rupture at any time, leading to acute myocardial infarction.

If you have chest tightness symptoms occasionally in the past, the symptoms will become more frequent and more serious in the near future. It also shows that the plaques that were previously stable are now slightly damaged and will develop into large ones at any time, leading to the occurrence of acute myocardial infarction.

In this case, you should go to the hospital as soon as possible and have medication or surgery.

Frequent palpitation

If you feel that you have always been flustered for no reason recently, don’t be careless. Palpitation is most common in arrhythmia, and serious malignant arrhythmia can lead to the risk of sudden death.

Therefore, frequent palpitation attacks should be treated in time.

Sweating heavily.

Before a heart attack, you sweat a lot on your body for no reason, such as neck, back, scalp, palms and soles. This may be a signal from the myocardium. At this time, you should be vigilant and beware of sudden death. It is best to stop all activities immediately, take medicine in time, and call 120 immediately if necessary.

Amanita, syncope

Blackness refers to the clinical symptom that the eyes can’t see or see clearly when they look at things, which is manifested by blackness in front of their eyes. Syncope in patients with heart disease is an important precursor of sudden death. Most syncope is caused by the sudden slowdown or stop of heartbeat, resulting in insufficient blood supply to the brain.

Once you have unexplained syncope, you should be very vigilant and go to the hospital as soon as possible to find out the reason.

Extreme fatigue and tiredness

Before sudden death, the whole body will have a serious sense of powerlessness and even a feeling of dying, which is the last warning given by the body.

ache

Pain response is the most easily grasped and perceived signal among the symptoms of sudden death.

When you feel severe, tight and crushing pain in your chest and feel breathless, you should be on high alert.

Also, if patients with heart disease often feel pain in the throat, shoulders, neck, chin and arms, they should also pay attention to the signal of myocardial ischemia, because when the pain of myocardial ischemia is transmitted to the central nervous system of the brain, it will be reflected in the spinal cord segment at the same level.

Therefore, it is necessary to pay attention to these cases of pain transfer and see a doctor in time.

Suddenly cold hands and feet

When the room temperature is normal and there are no other conditions, rubbing hands is mostly because after the heart has problems, the blood circulation becomes worse, the hands and feet are cold, and it seems to be "unconscious" to rub hands to keep warm, which is actually an alarm signal that the heart is about to have problems!

Recurrent gastrointestinal symptoms

Many patients with sudden cardiac death have recurrent gastrointestinal symptoms before their death, and many of them have no history of stomach trouble before their lives. This is one of the signals of heart attack. When these symptoms appear, timely rest can relieve discomfort, and if they are symptoms of heart disease, the above symptoms will not last for a long time, but will continue to be repeated.

Therefore, in the event of recurrent gastrointestinal discomfort, heart problems need to be taken into account.

As the saying goes, "Illness can last a hundred years". Let’s think about some people around us who are frail all the year round. They will always pay attention to their discomfort, but these young elites who have died suddenly are just the opposite. Because of their good health, they often get over it when they feel uncomfortable, but in the long run, they will be over-consumed and life-threatening.

Knowing the precursor of sudden death, people should check themselves to see if the above situation exists. If they find that they have the precursor of sudden death, they must seek medical attention in time and dial 120 if necessary.

Sudden death is also closely related to people’s living habits. Staying up late for a long time, playing games all night, lack of rest, uninterrupted working hours of the brain and heart, and heavy drinking are also the causes of sudden death.

Mary Zhang Xinyi and ＂Shan Yao＂ dueled Hua Chenyu to catch a giant fish of half a meter.

　　Beijing, August 5 (Xinhua)-The ninth program of the Star Travel Experience Variety Show "Patterns of Journey" of Oriental TV will be broadcast at 22: 00 on August 5. This week, the "flower tour group" bid farewell to Russia and came to Norway to continue the task of experiencing the wish list for netizens.

　　In the program, Gina suddenly felt unwell during the skydiving challenge and was sent to the hospital for examination, leaving only Lin Chi-ling to continue to complete this bold extreme challenge. Aarif Lee and Hua Chenyu, together with Zhang Xinyi, Mary and newly-joined Qiao Xin, entered the Norwegian forest to explore the legendary "Shan Yao". During the exploration, everyone unexpectedly became friends with Norwegian children who were outdoors. Zhang Xinyi and Mary crossed the language limit and enthusiastically sang children’s songs with them. Hua Chenyu’s initiative to please Shy boy was rejected by the other side. Finally, in the depths of the mysterious forest, people found the mysterious building that Zhang Xinyi and Mary couldn’t help screaming. What’s the mystery?

　　Hua Chenyu and Qiao Xin turned into "fishing up" and fished out a half-meter "fish god".

　　In the public’s impression, if you want to fish, you need a fishing rod, a hook and a bait. Otherwise, it will be Jiang Taigong’s fishing, and you can only take the bait if you wish. However, in this program, Aarif Lee used his own minimalist fishing method to complete the fishing challenge with only a fishing line and hook in his hand, which amazed Hua Chenyu and Qiao Xin.

　　At first, Aarif Lee wanted to show his fishing skills with a professional fishing rod. However, just after the preparation, Hua Chenyu and Bridgette, two "fishing whites", were attracted by this novelty activity and said that they would participate together. However, in the hands of two "fishing whites", the fishing rod and fishing line were always cut and disordered. Finally, Aarif Lee simply removed the fishing line and grabbed it directly with his hands, and developed a very simple "line-holding fishing method". Surprisingly, not long after Aarif Lee put the hook into the water, fish were hooked immediately, and the record of almost "second fishing" shocked Hua Chenyu and Bridgette who were still struggling with the boom.

　　After that, Hua Chenyu and Bridgette followed suit decisively and gained a lot. Not only did Bridgette catch a big fish bigger than Aarif Lee’s prey, but Hua Chenyu caught a big flat fish which was said to be very expensive and delicious by long line, and finally even caught a "fish god" who was more than half a meter long and seemed to be "refined". During the take-up process, the "Fish God" kept fluttering in the water, which made Hua Chenyu on the shore somewhat unstable. Can he successfully handle the "Fish God"?

　　Hua Chenyu was "disgusted" by Meng Wa, and Zhang Xinyi and Mary were crazy about children’s songs.

　　In addition to fishing in the water, the "Flower Group" also has an important task to find the "Shan Yao" in the Norwegian forest for netizens. It is said that these "Shan Yao" are the archetypes of the dwarfs in Snow White. However, walking into the vast Norwegian forest, before Shan Yao was found, the "Flower Troupe" became friends with a group of Norwegian children.

　　In the program, the "Flower Troupe" met Norwegian children who followed the teacher out for a picnic in the forest. Although the average age of these children is only five or six years old, they have begun to learn to take care of themselves and even cook food. In the face of the exotic "Flower Troupe", the children did not think that make a fool of oneself took the initiative to share food. Zhang Xinyi and Mary were amazed by their independent personality. At the scene, the two people enthusiastically sang songs with Norwegian children by relying on the world-wide children’s songs such as Little Star, and the happy picture was quite warm.

　　As the "Prince of Music" in the "Flower Troupe", Hua Chenyu also tried to communicate with a Norwegian boy who is very similar to himself with his guitar. As a result, the shy boy was ungrateful and kept avoiding it. But this aroused Hua Chenyu’s fighting spirit, and he kept chasing the little boy to perform and wanted to infect each other with music. Can Hua Chenyu’s music impress the little boy? Can the "Flower Troupe" find the legendary "Shan Yao"? More exciting, please look forward to Oriental TV’s "Travel Patterns" at 22: 00 on August 5.

How to realize remote and efficient operation and maintenance of equipment, analysis of IT operation and maintenance function of Sunflower Enterprise Edition

   [Tianji. com IT News Channel]In the information age, IT equipment generally supports the business of enterprises. Once these equipment have problems, it will have a great impact on the business and may cause irreversible accidents. In this context, operation and maintenance is extremely important, but the conventional offline operation and maintenance mode is costly and inefficient, so it is necessary to effectively introduce remote operation and maintenance management means.

    Therefore, how to build an efficient and professional remote operation and maintenance management system around a large number of IT equipment owned by enterprises, even commercial equipment widely deployed in the front line of business, is a compulsory course for enterprise IT departments.

    As a national remote control brand, Berry Sunflower provides a professional remote IT operation and maintenance management solution for enterprises, which is equipped with many practical operation and maintenance functions, which can help us to better implement remote operation and maintenance. Let’s take a look here.

   Remote IT operation and maintenance management: how to authorize and group a large number of devices

    When the number of equipment gradually increases to hundreds of units, the primitive and extensive management mode will be inadequate. Faced with this situation, we need to build a management system, in which the equipment is properly grouped and authorized to specific IT leaders, which is the specific means to build the system.

    ●  Equipment batch deployment

    Sunflower Enterprise Edition supports batch deployment. We found Equipment Management-Installation and Deployment-Software Customization in Sunflower Management Platform, and we can customize a remote control client software as required.

    After customization, we can install the installation package on the corresponding equipment in a unified way, and then complete the deployment, without debugging and setting each equipment separately.

   ●  Device grouping strategy

    Sunflower Enterprise Edition is equipped with the function of "grouping strategy", which provides two grouping strategies: automatic grouping and manual grouping, which can be selected when customizing the installation package.

    Manual grouping, that is, when customizing the installation package for installation and deployment, you can manually select the grouping where your own equipment is located. This mode is more common in scenes such as chain stores, and the grouping operation is actually delegated to the front line, and the grouping is directly established during the initial deployment of equipment, reducing the burden of grouping management at headquarters.

    Automatic grouping, that is, when customizing the installation package, you can set the package to automatically enter a certain group. We can customize an installation package for each group according to the groups we need to divide.

    Of course, we can also set the automatic grouping policy: when the system detects whether the device name/remark name contains the specified keyword, it will be automatically assigned to the specified grouping.

   ●  Equipment authorization management

    Equipment authorization, that is, which equipment is specifically managed by each front-line operation and maintenance account. Sunflower Enterprise Edition supports authorizing the equipment under the main account to a specified account or account group. Operation and maintenance personnel can log in with the employee account assigned by the enterprise, and can see the equipment they can manage, so as to realize the management by departments, regions and powers.

    The authorization of equipment can be relatively long-term or short-term to meet the different needs of internal operation and maintenance management and external supplier access.

    If it is necessary to establish an efficient short-term authorization system, enterprises can consider setting up a flexible "guest account pool". The permissions of these accounts are set according to the external remote control requirements, and they are allocated when needed, and the permissions are taken back immediately after the relevant business ends.

   How to achieve efficient access to IT operation and maintenance capabilities?

    Facing a large number of devices, how to further make remote operation and maintenance efficient? How to quickly feed back the relevant information of front-line equipment to headquarters IT? Faced with these problems, sunflowers are equipped with the following functions.

   ●  Batch distribution of files

    Sunflower provides file batch distribution function. When we need to upgrade and iterate on the controlled equipment in the daily operation and maintenance process, we can use this function to distribute files such as update patches to the controlled terminal in batches, without transmitting files one by one, which is fast and convenient.

    ●  The cloud policy uniformly adjusts the settings of the controlled end.

    If we need to adjust the settings of the sunflower controlled terminal, or even part of the settings of the controlled terminal equipment, do we need to manually adjust them one by one? The answer is no.

    Sunflower Enterprise Edition provides the "cloud strategy" function of the client. We can directly create the corresponding strategy in the cloud, adjust the functional configuration of the client, and send these configurations to the front-line equipment in real time without repeated deployment in cover the installation.

    These settings include: whether to allow local modification of access password, update of verification code, whether to allow startup of privacy screen, etc. It is worth mentioning that this function can now set the desktop wallpaper of the controlled device in a unified way, which is practical when some chain enterprises need to change the desktop background in a unified way on holidays.

   ●  Screen wall+equipment alarm strategy

    Unattended equipment, how can we * locate the fault in time, or warn related problems? Screen wall and alarm strategy are very practical functions.

    The screen wall function provided by sunflower can monitor the pictures of multiple devices at the same time, and the usage and running status of the devices can be seen at a glance.

    At the same time, Sunflower Enterprise Edition also supports setting device alarm strategies, such as setting thresholds of performance indicators of devices, networks, etc., and triggering alarm notifications when the performance of devices reaches the set thresholds.

    How to ensure the stability and security of remote operation and maintenance?

    IT operation and maintenance, stability and safety of batch equipment are also very important indicators, so sunflower is also equipped with many practical functions.

   ●  Traceless operation and process protection

    If the remote control software of unattended equipment is accidentally turned off and is in a "lost connection" state, it is very troublesome to restart the software offline if you want to re-establish the connection. In order to avoid the above situation, Sunflower supports the start of seamless operation and process guardian.

    After the seamless operation is started, desktop shortcuts, tray icons and bubble reminders will not be displayed, and the software uninstallation entrance will be hidden to prevent the software from exiting due to misoperation; After the daemon is started, it can automatically restart when the sunflower enterprise client is unexpectedly stopped.

   ●  Custom privacy screen

    Sunflower Enterprise Edition privacy screen supports user-defined display content. After this function is turned on, the information of privacy screen will be displayed on the screen of the controlled terminal during remote operation and maintenance, and the specific operation process will not be seen or disturbed.

   ●  Log, watermark, screen recording

    In order to ensure the safety and traceability of the remote operation and maintenance process, Sunflower Enterprise Edition supports the setting of watermark function: the remote control window is superimposed with plaintext watermark, and the watermark content is based on information such as the identity of the operation and maintenance personnel, so as to standardize the operation and maintenance behavior of sensitive positions and ensure the information security of the controlled equipment.

    In addition, the operation and maintenance process supports the whole process of "cloud video recording", and the details of remote operation and maintenance are recorded in the form of video and stored in the cloud. Remote control log can accurately record the time and behavior of operation, and ensure effective traceability when security incidents occur.

   Ending:

    The above is the related content of how enterprises use sunflower to realize efficient remote IT operation and maintenance. As a national remote control brand, Berry Sunflower and Shanghai Software Industry Association issued the industry * group standard of remote control, which accelerated the application of remote control software technology in a wider range of scenarios in the future. At the same time, Sunflower parent company "Berry" has been deeply involved in the field of remote connection for 18 years, with 90 million+registered users, 1.1 million+corporate customers and as many as 2 billion access devices.

    If you are interested in other product schemes or cases of sunflower remote control, please go to official WeChat official account or official website for more details.

How fierce is the Dongfeng Warrior 917 Lorenz M800 Star Chariot？

Many times, as long as I hear the words "big guy", "off-road vehicle" and "land overlord", many fans may guess that I am going to talk about a hard-core off-road vehicle again. Yes, what we are going to talk about today is the brand-new model announced by Dongfeng Technology: Dongfeng Lorenz M800 Star Chariot. As a high-definition version of Warrior 917, this model was jointly built by Warrior Technology and Lorenz. Before the Chengdu Auto Show, we filmed this warrior 917 Lorenz M800 in the shed. Let’s reveal the secret for you and see how fierce this new car is!

Xiaomi’s latest TV resolution is less than 1080P？ What should we pay attention to when buying a TV？

Since the TV entered our family, it has brought a lot of enjoyment to our lives, and with the development of technology, the price of TV sets has gradually begun to drop. As a "price butcher", Xiaomi recently launched a new entry-level monitor – Xiaomi TV EA32, model L32MA-E, with Unibody metal body, starting at 599 yuan.

The new EA32 is equipped with a 32-inch full screen, supports a 60Hz refresh rate, and uses a quad-core processor. The storage specification is less than 1GB + 8GB, supports 2.4GHz and 5GHz dual-band Wi-Fi, has 2 USB interfaces, 1 HDMI interface, AV interface, etc., and runs the MIUI for TV 3.0 system.

The overall cost performance is still very good, but the resolution of the new product is only 1366×768, which is relatively low. Even if it is used as a flat replacement monitor, it feels just passable. If you don’t care about image quality or rent a house and just want to buy a TV, you can still buy this one. For friends who want to get a better experience, it is recommended to pay attention to the following points when purchasing a TV.

1 clarity

The definition of the TV is the resolution of the TV, the higher the resolution, the clearer the TV picture will be, and now there are many 4K TVs on the market. If the budget is enough, it is better to start directly, which can bring better visual enjoyment. In addition, you have to pay attention to the phenomenon of true and false 4K, real 4K effective pixels 8.40 million, fake 4K only 6.15 million, if the merchant writes 4-color 4K, then it is fake 4K.

2 image quality

Image quality is the core performance of every TV, and the image quality is naturally comfortable when it looks good. TV image quality is mainly affected by two factors, one is the image quality processing technology based on hardware, and the other is the optimization based on software, both of which are equally important. Of course, if you want to simply choose a TV with good image quality, Luxgen chooses MiniLED panel, 120Hz resolution, color gamut greater than 93% DCI-P3, light control partition technology, and motion compensation technology, which basically meets these major needs. TV image quality will not be worse.

3 sound effects

TV sound quality should be considered well, first of all, the power should be large, and the choice of high power above 10W can basically meet the needs of the living room or bedroom; secondly, there should be independent cavity sound; finally, if the budget is sufficient, choose Dolby sound effects, DYTS, etc., which can improve the actual effect of sound effects and make the listening experience more intense.

4 sizes

The viewing distance is 2.5-3 meters, choose a 55-inch or 65-inch TV;

The viewing distance is 3-3.5 meters, choose a 65-85 inch TV;

The viewing distance is 3.5-4 meters, choose a 75-98 inch TV;

With a viewing distance of 4-4.5 meters, choose an 85-110 inch TV.

Of course, this suggestion is not very accurate. If conditions permit, it is still recommended to experience the viewing experience of different sizes of TVs offline before purchasing.

5 Hardware

Hardware includes processors, memory, interfaces, and so on.

The processor mainly affects the running speed and fluency of the TV system. At present, the mainstream mid-to-high-end is the A73 quad-core processor, followed by the A53 dual-core + A73 dual-core and A55 quad-core. You can refer to and compare more.

Memory can be divided into random access memory and storage memory. Random access memory mainly affects the smoothness of the TV operating system. Generally speaking, 2GB is enough; storage memory is the capacity that can be stored inside the TV. If you like to install various APPs or download things, it is recommended to choose large memory.

Of course, the richer the interface, the better. The most common ones are HDMI, USB 2.0, USB 3.0, WIFI5.0G, antenna input, AV input, etc. If you like to play games, it is recommended to choose an HDMI2.1 interface.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

An internationally renowned scientist at Harvard Medical School, one of the most influential figures in Time magazine, and the best-selling book Life: Why We Aging — — And why we don’t have to age, David Sinclair (David Sinclair), an anti-aging tycoon, followed NMN and resveratrol to promote another life-prolonging anti-aging substance on Twitter — — α -ketoglutaric acid (AKG)

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

The "epic" anti-aging substance AKG can actually reverse the "aging clock" for 16 years.

On September 1st, 2020, the world’s first professional research institute on aging — — Barker Institute of Aging published the research on AKG’s anti-aging in Cell Metabolism, and the title of the paper was "alpha-ketoglutarate, an endogenous metabolite, stretches lifespan and compressors in aging mice". The content is as follows: Experiments show that AKG can reduce the biological physiological age by 8.5 years on average, and even by 16 years at most. These results are based on the clinically relevant markers of healthspan, which is the first time in the research involving mammals.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

Image from cell metallurgy, 2020, doi: 10.1016/j.cmet.2020.08.004.

The so-called AKG means α Alpha-Ketoglutarate (AKG), an important metabolic intermediate in the tricarboxylic acid cycle, is a key node connecting carbon-nitrogen metabolism in cells. AKG determines the overall rate of trihydroxy acid cycle. AKG can regulate longevity by affecting mitochondrial function, inhibiting mTOR signal, inhibiting ATP synthase expression and indirectly activating Sirtuins protein.

As early as 2014, AKG attracted people’s attention as a possible anti-aging tonic. At that time, the research report of the British magazine Nature said: "Adding α -Ketoglutaric acid can prolong their life by about 50%. "

Professor Brian Kennedy, a genetic biologist who is the main person in charge of the project, said: "We screened dozens of compounds related to aging, and the last molecule that jumped out was α -Ketoglutaric acid, so I finally decided to carry out further research that is not as good as animals. "

According to the interim data published in the first half of this year, about two-thirds of the subjects showed the effect of reducing life expectancy, with an average life expectancy of 12% and an average incidence of 46%. According to the final experimental data, the subjects fed with AKG scored more than 40% higher in the "weakness" test, which was based on 31 physiological attributes, including hair color, hearing, gait and grip strength.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

It is worth noting that the life span of female mice in the experiment is 8% to 20% longer than that of the control mice, and if compared with humans, it is equivalent to extending the life span by up to 16 years.

And then professor Brian KennedyAnother heavy experimental result published in Nature further proves the influence of AKG on human anti-aging.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

In the experiment, Professor Kenney’s team organized 42 middle-aged and elderly people (with an average age of 63 years) to supplement for 7 months.AKG and vitamin compound preparation. Seven months later, the researchers re-measured the physiological indexes of this group of middle-aged and elderly people. The results showed that after 7 months of AKG intervention,The physiological age of this group of middle-aged and elderly people is 8 years younger on average.. At the same time, the participants’ sleep quality and other indicators have also improved significantly.The energy level jumped by about 50%.

Professor Kenney believes that this result confirms his initial guess: "In a sense, the level of AKG will decline with age. So we need to supplement it and let the body return to a younger level. "

At the same time, he also cautiously indicated that AKG needs further experiments to develop in view of the objective problems such as the small number of samples in this experiment.

Unlock the time code and refuse to grow old meekly.

Professor Kenney once said with confidence: "There is no reason why you can’t be interfered when you get old" and "Please don’t meekly accept getting old".

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

There is still a long way to go to study AKG, and how to use it better is the focus of people’s attention. It is reported that AIBORST (Albers Special), a well-known American anti-aging brand, recently announced the news that its first dietary supplement with AKG as the main body, Gene Kangyuan AKG18000, will land in the China market. I believe that in the future, with the deepening of AKG research, a new era that belongs to the health of the whole people and is rooted in anti-aging will soon open.

Be alert! Scalpers are eyeing online celebrity catering.

　　Nanjing’s "Diandude" is on fire. A Cantonese-style tea restaurant that has only been in Nanjing for more than 20 days has gained more than 1,300 comments from the public. However, the opening of the store has also brought troubles to the store — — The "yellow cattle" stared at the diners who lined up to eat. On the idle fish of the second-hand trading platform, search with "Diandude Nanjing" as the key word, and there are not a few "scalpers". Small table 70 yuan, middle table 80 yuan, and big table 100 yuan will be charged separately when they enter the store.

　　You have to find a "scalper" for a meal. Do you think it’s ridiculous? However, it is also a fact that customers queue up for consumption in many online celebrity restaurants in Nanjing, and scalpers smell "business opportunities" from them. They can enter without queuing, pay on the spot, and refund fees after the time limit. The slogan is eloquent and attractive, and scalper tickets are not worried about buyers. For young consumers who are keen on "punching in friends", this "handling fee" is not unbearable, and it is a cup of milk tea money at most for each person; On the other hand, spending hundreds of yuan saved the lengthy queuing time and ended up at ease.

　　Of course, not everyone is willing to spend this "wasted money". A grandmother who is over 60 years old in the "Diandude" team is puzzled by buying scalper tickets: "Why spend money to find someone to queue up? I don’t have much, just more time. " A consumer wrote angrily on the comment software: "It’s no problem to queue up for tickets normally, but the scalper at the door has dozens of tickets in his hand. How do merchants invoice?"

　　According to insiders, the "yellow cattle" were originally just some people queuing up for customers in advance to get a little hard work. Gradually, they are not satisfied with being single-handed "brokers", but form a tight network of purchasing in front and selling in the rear. From being hired to buying tickets to taking the initiative to hoard tickets and drive them up, the tickets for concerts that were robbed within 5 seconds were created, and the same was true for three hours without eating at the gates of Gelaoguan and Diandude.

　　Merchants are not unaware of this. On the contrary, some merchants even colluded with scalpers to create false and hot scenes, forming a gray industrial chain between online celebrity stores and scalpers. Last year, it was revealed that online celebrity Bakery Master Bao hired a fake team of yellow steaks in a store in Wuhan. The scalpers mixed up with ordinary customers to queue up for shopping, and then turned around to the kitchen to return the cakes they just got to the merchants. On average, a single order could earn "labor expenses" from 25 yuan to 30 yuan. After the incident was exposed, the number of people queuing in the store plummeted by 70%, and the popularity was "diving".

　　According to industry insiders, there are two main types of scalpers in the catering industry. One is that the company hires scalpers to queue up before it becomes famous or when a new store opens, and the other is that there are endless queues in front of the door, which leads to some "scalpers" who make profits. However, no matter which one, it will create a scene of hot business in restaurants for the outside world.

　　When some shops in online celebrity tried to create a false popularity, most honest businesses resisted. According to the clerk of Ge Laoguan in Nanjing Aishang Tiandi, consumers can get the number online through Ge Laoguan’s WeChat WeChat official account, and merchants will limit the number of times to get the number online by setting the ID of the account, up to five times a week. At the scene, the clerk tries to ensure that one person has one number as much as possible, and tries to avoid the phenomenon that scalpers repeatedly take numbers. "Although there are still scalpers scalping tickets, it is much better than before." The clerk said.

　　It is a common phenomenon that customers queue up in online celebrity stores, which makes the waiting time rich and interesting for consumers and tests the wisdom and intentions of businesses. When customers line up at Haidilao, the restaurant not only provides free snacks, drinks and fruits, but also provides free manicure and shoeshine projects, and even prepares colored paper for ingenious customers, which can fold paper cranes and fold stars to deduct the meal expenses, so that consumers can enjoy the process of waiting in line. The practice of "fishing at sea" is worth learning from many online celebrity stores. (trainee reporter Shen Jiaxuan)

What if the laptop doesn’t work？ The laptop doesn’t work. Solution [Detailed explanation]

With the continuous development of science and technology and the improvement of people’s living standards, many people can’t live without computers now. We need laptops at work and at home for leisure. No matter how good the quality of this electrical product is, it is inevitable that the machine will not work during use. so The laptop won’t turn on What are the correct processing steps? How to deal with it correctly? Let’s learn more about it together.

One, The laptop won’t turn on Correct processing steps of

step

The first step is to analyze according to the specific situation. If the power supply doesn’t respond, we need to check whether it is a power supply, poor contact, hardware and other problems. If it is, then go to the second step. If it is unable to enter the system, it may be an operating system or software problem, and go to the third step.

Second step

If it is determined that it is a power problem, check whether the power cord is plugged in properly, and then check whether the plug is loose. If the notebook you are using is a battery, plug it in and try again. You can go to a friend or go to a computer repair shop or a sales store to find the same type of power supply and try it. After plugging in the power, press the power button again. If it still won’t turn on, press it for a while. If someone else’s power supply can be switched on, it means there is something wrong with the power supply. If it proves that there is nothing wrong with the power supply, it may be the hardware. Go to step 5.

Third step

The operation flow of the third step is like this. First, press F8 for a long time, then enter the options page, select "Last Correct Configuration" and press enter. If you can get into the system, it is likely to be caused by virus infection, incompatibility between hardware drivers and the system, operating system and so on. After entering the system, run anti-virus software to kill the virus. If there is virus, restart the computer after anti-virus. If it is not normal, it may be caused by incompatibility between device drivers and programs. Delete drivers such as video cards and network cards, and restart after deleting drivers. If there are still problems, then go to the next step.

Fourth step

Repair, install or reinstall the system, set "CD-ROM drive as boot device" in BIOS, then insert the system disk, and press R key to "repair and install". If the fault remains, just at the beginning of entering the system, choose "one-click gost restore system" or reinstall the system using the system disk.

Step five

The fifth step is the hardware problem. The first thing we need to do is to disassemble the notebook, and then check whether the hardware is loose. Generally, if the hardware is not plugged in properly, there will be an alarm sound. Long sound means that the memory stick is not plugged in tightly, one long and one short means that there is a problem with the memory or motherboard, and one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, clean it first. In addition, we should pay attention to whether it is caused by the new hardware. If it is normal before replacing the hardware, it will be abnormal after replacing it, then check whether it is compatible. If it can’t be started at this time, send it for repair, and professionals will check whether there is any problem with your hardware one by one.

Second, the notebook computer can’t be turned on. Matters needing attention

There are many reasons why the notebook computer can’t be turned on. We must not be upset during the investigation. We must be careful and careful during the inspection. If we don’t know much about the computer, don’t tinker with it to avoid more damage. The solution is to find a professional to repair it in time.

The above is the relevant content about the correct processing steps of notebook computer not turning on, I hope it can help everyone!

AI grabs a job with someone？ Don’t panic, there will be a new division of labor between man and intelligent robot.

　　Machines are good at solving problems, but they can’t ask questions and are not good at innovation. Therefore, the most valuable social occupations in the era of machine learning are entrepreneurs, innovators, scientists, creators and other talents who can analyze problems to be solved, opportunities to be explored and fields to be explored.

　　How awesome is artificial intelligence now? — — Ali’s mother’s artificial intelligence copy can generate 20,000 advertising words in one second, and Ant Financial’s AI has realized that four people serve tens of millions of users of 27 fund companies. After more than ten years of training, ophthalmologists can identify about 40% of keratitis, while Zhejiang University’s artificial intelligence can identify 84% and never get tired. As for translation, it is a piece of cake for Iflytek’s artificial intelligence to communicate in countless languages at the same time.

　　As early as 2016, based on the artificial intelligence technology at that time, Oxford University professors Carl benedikt Frey and Michael A. Osborne predicted that in the next 20 years, 47% of jobs in the United States, 69% in India and 77% in China are likely to be replaced by automation brought by machine learning.

　　Don’t panic, machines will not completely replace manpower.

　　"Artificial intelligence will definitely eliminate some industries and transform some industries." Xi Youmin, executive president of Liverpool University of Xi ‘an Jiaotong University, positively predicted that "many jobs may be lost, and many majors will be lost. Simple accounting will soon be replaced, and many people in the bank will lose their jobs."

　　But don’t panic, some people in the future are irreplaceable. While replacing and strengthening some industries, artificial intelligence and robots will also breed many new industries. For example, in today’s unmanned aircraft, one aircraft replaces a pilot, but there are 60 big data operators behind it.

　　Some experts also pointed out that people and intelligent robots are not substitutes, but will form a new division of labor. This new division of labor is reflected in the optimization of work performance by using artificial intelligence and machine learning; Machines are good at solving problems, but they can’t ask questions and are not good at innovation. Therefore, the most valuable social occupations in the era of machine learning are entrepreneurs, innovators, scientists, creators and other talents who can analyze problems to be solved, opportunities to be explored and fields to be explored.

　　With the deep development of artificial intelligence technology and the wide application of robots, people will be liberated from many traditional production activities, have more leisure time and more powerful support means, and make life more interesting and colorful. Innovation and creativity will become necessities in life and work, and people will have more opportunities to engage in creative work.

　　But Xi Youmin warned that all new jobs will only become more and more complicated, not simpler. "In the future, you won’t create jobs that you can get as long as you get a few points right.".

　　The Times of Artificial Intelligence, which was read by Fan Deng, the founder of Fan Deng Reading, set off a listening craze on the Internet. But few people know that Fan Deng majored in metal materials and heat treatment in university. "In college, I actually didn’t learn anything." He joked, "The most important thing my alma mater taught me was to make me feel that I could learn something." What impressed him the most was that he once participated in a debate on behalf of the school. In order to win the championship, he and his classmates browsed the library materials, read countless books and learned a lot.

　　This self-learning ability has become Fan Deng’s core competitiveness today, and it is also the root that he thinks he will not be replaced by robots.

　　People who are least like machines are more adaptable to the era of artificial intelligence.

　　Children in kindergarten can recite two sentences of poetry and speak two sentences of English, so parents are very happy. After school, multiplication tables and problem-solving methods will always be concerned, but these are not important in the era of artificial intelligence. "Because there are search engines and mobile phones now, people can easily find the knowledge they want, and the function of traditional education to eliminate ignorance has disappeared." Xi Youmin believes that it is easy to have knowledge in the future, and it is important to judge the ability to integrate this knowledge.

　　From the perspective of practitioners, Lv Cheng, general manager of Baidu Smart Home Hardware, has a deeper measure of talents in the era of artificial intelligence. Lv Cheng does not deny that future talents also need to master a lot of professional knowledge. But he put imagination first in the future talents. "The artificial intelligence industry is basically predicting what the future will be like. But my theory is that no one can predict anything, so you need to be very bold. Not from the perspective of landing application, but from the system level and at a higher level, we have a vision and idea for the future society. "

　　He believes that the most important quality of practitioners in the era of artificial intelligence is to have high moral standards. "Because artificial intelligence has a huge challenge, it is whether human beings can control its boundaries and can’t resist opening Pandora’s Box." In practical research, many application scenarios of artificial intelligence are actually full of temptations. Practitioners need to consider whether a certain technology will have a fatal impact on human society in the future and cannot be controlled by artificial intelligence.

　　In the final analysis, machines serve people, and how high people stand, how much help robots will have. Just like a smart phone has many functions, but most people only play 30% of its functions. "If we want to make our life more colorful with the help of robots, we must constantly improve ourselves." Xi Youmin believes that general education, literacy education and art education will become more and more important in the future, and schools need to cultivate students’ autonomous learning ability, questioning ability, interpersonal communication ability, innovative thinking ability and future planning ability.

　　"Who can survive in the future society? The most important thing is that you have to become the person who is least like a machine. " Fan Deng summed it up in one sentence.

　　But from the most realistic point of view, computer science will become the "main course" in all schools. Now Zhejiang University requires all undergraduates to learn programming, even the department of archaeology is no exception. This is the key for students to enter the era of artificial intelligence.

　　How to change education? It is still a problem being explored.

　　In April this year, the Ministry of Education issued the "Action Plan for Artificial Intelligence Innovation in Colleges and Universities", which made major arrangements for the innovative development of a new generation of artificial intelligence from the level of higher education.

　　Artificial intelligence affects education, not simply by offering artificial intelligence courses in schools, nor by offering artificial intelligence majors in schools. What the educational circles need to study is how the whole education adapts to the social problems after artificial intelligence because artificial intelligence has changed the world.

　　"For many years, the school has only paid attention to professional planning, curriculum design, syllabus, teaching, etc., and the future study is likely to be that people have laid a certain learning foundation and skills when they are young, and then live and work with their interests and opportunities, and they have to conduct specific studies as needed, thus making lifelong learning a habit and necessity." Xi Youmin believes that in this case, teaching is no longer simply to teach knowledge, but to guide students to cultivate problem awareness, learn to search for knowledge, integrate knowledge and solve problems, and improve their abilities of communication, cooperation, expression and execution in this research process.

　　This also means that the teaching mode of the school and even the campus form may change. In the future, students don’t necessarily have to spend four years for undergraduate study, two or three years for postgraduate study or three to five years for doctoral study. Instead, they need to make use of resources and technologies such as the Internet and schools to continue their self-learning.

　　The future university will be a learning center, a resource center, a research and development community, an innovative ecology and a Industry-University-Research social community. Here, teachers interact with classmates when they want to learn, try creativity with resources and experimental environment when they have ideas, seek answers with R&D center when they have doubts and questions, practice through innovative ecology when they have technology or business model, and create and share the value of innovative products or services through Industry-University-Research Community, thus promoting social progress and development.

　　At present, Tsinghua University, Zhejiang University, Zhejiang University of Technology and other well-known universities have deep cooperation with Baidu, Alibaba, Tencent and other enterprises. Zhongke Shuguang, the leader of supercomputers, is also cooperating with universities to introduce the experience and projects of enterprises into practical courses in universities, so that doctors in research institutes can share their experiences with students. Song Huaiming, chief scientist of Zhongke Shuguang Big Data, believes that the core idea of school-enterprise cooperation is to integrate the advantages of enterprises in artificial intelligence and advanced computing with the educational concept of the school to better cultivate practical talents.
