In the field of long video, three video platforms, iQiyi, Youku and Tencent Video, have formed a "three-legged" trend. Three platform opportunities can lead the development direction of the long video industry.

On February 28th, Beijing time, iQiyi (NASDAQ: IQ) announced the unaudited financial report for the fourth quarter and the whole year as of December 31st, 2019. The financial report shows that in the fourth quarter of 2019, iQiyi’s revenue was 7.5 billion yuan and its net loss was 2.5 billion yuan. Both revenue and net loss were better than expected.

Although iQiyi, Youku and Tencent Video are backed by BAT, they still lose money and continue to burn money. The profit seems to be in the foreseeable future. Judging from the latest financial report released by iQiyi, the loss is narrowing. Is this a positive signal?

Why is the long video platform difficult to make a profit from the iQiyi financial report?

According to the financial report, Iqiyi’s Q4 revenue in 2019 was 7.497 billion yuan, up 6.7% from 7.027 billion yuan in the same period of last year, up only 1.4% from 7.397 billion yuan in the previous quarter.

As can be seen from the above figure, although iQiyi’s revenue maintained growth, the year-on-year growth rate continued to decline. Iqiyi’s income mainly consists of membership services, online advertising services, content distribution and other income.

In the fourth quarter, Iqiyi’s membership income was 3.861 billion yuan, up 20.6% from 3.201 billion yuan in the same period of last year, up 3.9% from 3.717 billion yuan in the third quarter. In the fourth quarter, membership service revenue accounted for 51.5%, making it the largest source of income for iQiyi. Iqiyi said that the revenue growth was mainly due to the high-quality content and diversified operations, which promoted the growth of the number of subscribers.

Gong Yu, founder, director and CEO of Aiqiyi, said that the revenue of Aiqiyi’s membership business increased by 36% in 2019, and the number of subscribed members reached 107 million. Looking forward to the next decade, the upcoming continuous innovation of 5G commercial and artificial intelligence technologies will bring great opportunities to Aiqiyi. As users in China are more and more willing to pay for high-quality content and use convenient payment methods, they will jointly bring great growth potential to the iQiyi business.

According to the financial report, as of the end of the fourth quarter, the number of subscribed members of iQiyi reached 107 million, and the number of subscribed members increased by 22% year-on-year. On the whole, the growth of subscription members is also slowing down, and with the decline of demographic dividend, membership growth seems to have peaked.

Online advertising revenue was 1.883 billion yuan, down 14.6% from 2.204 billion yuan in the same period of last year and down 8.9% from 2.067 billion yuan in the third quarter. In the fourth quarter, online advertising revenue accounted for 25.1%, and the contribution of online advertising revenue continued to decline. Iqiyi said that macroeconomic challenges have led to a decline in online advertising revenue. Yiguan Finance believes that the decline in online advertising revenue is also related to the rapid development of short video platforms. With the rise and rapid development of short video platforms such as Aauto Quicker, Tik Tok and bilibili, users’ attention and advertisers’ budget have shifted, and the advertising business of long video network has been robbed of "share".

Content distribution revenue was 878 million yuan, a year-on-year increase of 68%. Content distribution income mainly comes from broadcasting authorized content. In 2019, hit dramas, such as Little Joy, Dear, Love, and Joy of Life, were distributed by iQiyi. From the perspective of revenue growth, the distribution of these hit dramas has achieved good results.

In the fourth quarter, the income from other businesses of iQiyi was 874 million yuan, down 21% year-on-year. In 2019, the annual revenue was 3.7 billion yuan, a year-on-year increase of 30%. This is mainly due to the growth of many vertical businesses, especially the strong growth of game business after the acquisition of Tianxiang Mutual Entertainment.

Thanks to the reduction of content cost, iQiyi’s Q4 net loss in 2019 was 2.49 billion yuan, narrowing by 28% year-on-year and 32.6% quarter-on-quarter. However, in 2019, iQiyi lost 10.3 billion yuan for the whole year, still showing an expanding trend year-on-year.

According to the financial report, in Q4 of 2019, the operating cost of iQiyi was 7.914 billion yuan, and the content cost was 5.7 billion yuan, accounting for 72% of the operating cost. Content cost includes copyright purchase cost and content production cost.

Gong Yu, founder, director and CEO of iQiyi, mentioned in the earnings conference call that the content cost in 2019 only increased by 6% because of the continuous optimization of the content structure. The financial report shows that in 2019, the content cost of iQiyi was 22.2 billion yuan.

As can be seen from the balance sheet of iQiyi, the content assets of iQiyi include current assets-net value of copyright content, non-current assets-net value of copyright content, and non-current assets-net value of self-made content.

The financial report shows that as of December 31, 2019, iQiyi’s self-made content assets were 4.355 billion yuan, an increase of 16.6% compared with 3.736 billion yuan in the same period of last year; At the end of the period, the authorized content assets totaled 7.51 billion yuan, down 3.7% year-on-year.

From the changes of self-made content assets and authorized content assets, iQiyi achieves structural optimization by increasing the proportion of self-made content and decreasing the proportion of authorized content.

Gong Yu said at the conference call that film and television plays are still the main driving force for members to add value. At present, the hit dramas on the platform of iQiyi, such as Joy of Life and Dear, Love, all belong to copyrighted works.

Self-made video content, which will involve IP copyright purchase of film and television dramas, actor pay, shooting and other production costs, which are all important items of cost expenditure. The self-made variety "Qi Pa Shuo" has continued for six levels, and the topic heat has remained unchanged. "Sword Dynasty", starring Li Xian, a streaming star, is popular in Iqiyi. Although the limitation of star pay and the rising trend of drama prices slow down, the cost of purchasing copyright and the cost of self-made drama and variety shows decrease, it still cannot reverse the loss of video platforms.

In the case of membership growth meeting the ceiling, video websites began to change their thinking and tap the value of membership. If video websites want to turn losses, they need to constantly try new business models.

In terms of member value-added services, the charging mode of "member-on-demand in advance" launched by the video platform was criticized by the whole network and was questioned as "ugly", but it did not stop the determination of video websites to implement the charging mode of "member-on-demand in advance", which will become a normal broadcasting mode in the future.

Gong Yu thinks that although there are relatively few dramas adopting this mode at present, it accounts for a small proportion of the total revenue, but this mode is successful. "In the future, we will take this mode as a normal way of broadcasting. At present, the impact of advanced on-demand on the average revenue per user (ARPU) in the fourth quarter of 2019 and the first quarter of 2020 is not great, but it will be an important way to improve ARPU in the future. "

Iqiyi is constantly changing in the form of advertisements, such as patch advertisements and original small theater advertisements for online dramas. Iqiyi is also constantly trying to make use of advertising resources. Although Iqiyi members have purchased VIP members, they still have to watch advertisements. For example, in a 45-minute episode, all kinds of advertisements are inserted in the title, preview, film and ending, and even members are not spared. Some members can close it manually, while others can’t close it by force.

Iqiyi also said that the membership fee has increased. With the development of video websites for many years, people in China have a certain understanding of the paid membership model, but the acceptance of the paid membership model in China is not so high. In the long-term competition, video websites attract paying members through promotion, although it can boost revenue growth, but it is difficult to achieve profitability. Under the situation of tripartite confrontation, if only one party announces the price increase, it is likely to cause the loss of users.

Video websites are still content-oriented. Yiguan Finance has conducted a small-scale survey. Most paid members of video websites said that a video website member can almost meet their own needs for watching movies/dramas. Which platform can meet your own viewing needs, you will choose which platform, and you will not love a certain platform alone. There are also some users who have registered a number of platform members, but they will not buy annual members, but will only choose monthly membership when chasing a favorite film and television drama.

From this point of view, the loyalty of video platform users remains to be assessed. Whether the video website has enough rich content such as TV dramas and variety shows is the key to retain users. After all, users pay for high-quality content, and the continuous output of high-quality content is the key to the continuous growth and retention of paying users on the platform.

In addition, some insiders told Yiguan Finance that there is another factor in the loss of video websites, that is, the pressure on servers and bandwidth. The video platform should ensure that hundreds of thousands or even millions of people can watch online at the same time, and sometimes upload data traffic such as barrage. These fixed expenses are not small.

With the sudden outbreak of the COVID-19 epidemic, everyone was forced to stay at home and play drama. As a result, when I wanted to meet you was updated on February 26th, iQiyi collapsed, and "iQiyi collapsed" was returned to Weibo for hot search. From the technical principle, there are two reasons for the server crash, one is that the server content is tight, and the other is that the service design is flawed. It seems that Ali, JD.COM and others built their own cloud computing data centers for a reason.

In the layout, short videos, long videos and short videos erode each other and fight hand in hand?

Typical Internet users will allocate their online entertainment time to many different fields, including video (Youaiteng’s three long video websites; Tik Tok, Aauto Quicker and other short video sites) game videos (Tiger Tooth, bilibili, Betta Fish, etc.) and news push platforms. With the disappearance of traffic bonus, the peak of membership and the continuous loss, iQiyi needs new stories to enhance its commercial imagination. With the rapid rise of short videos, Iqiyi is constantly trying to seek new breakthroughs.

In fact, iQiyi has launched a variety of short video products, such as gingerbread, whale eating, natto, Jinshi and many videos. Although it failed to attract enough attention, it never gave up. Currently in the "Small Video" entrance of the top column of iQiyi app.

According to Tech Planet, iQiyi recently launched a short video featuring short videos of young trends. Iqiyi launched the "Shake Short Video" this time, on the one hand, it is an expansion and attempt of its own short video classification, on the other hand, it is to seize the popularity of 5G, constantly innovate, accelerate trial and error, and strive to create an explosive short video APP.

For the layout competition in the field of short video, at the conference call of Iqiyi’s 2019 Q4 and annual financial report, Gong Yu, the founder and CEO of Iqiyi, announced that he planned to launch a YouTube mode App called "On Time", and said that Ge Hong, who had rich technical and management experience in companies such as Facebook and Airbnb, would fully lead the business. This seems to show the determination of short videos in the layout of iQiyi.

It is reported that there will be two main categories of "on-demand" video content. The first category is PUGC content, which is mainly uploaded by MCN, individuals and professional organizations. In addition, the long video content of iQiyi will also be played on-demand, thus forming a strategic synergy of "long video+short video".

The content production methods of short videos are mainly PGC (professional production content) and UGC (user-produced content), which are mainly realized by advertising. The long video is either self-made or needs to buy copyright, and the realization methods are mainly user payment and advertising.

In the field of short and medium videos, iQiyi will face the competition from headline department, bilibili and Tik Tok.

Headline has a huge user base and a high daily activity rate, which lays the foundation for the commercial realization of long video. Headlines rely on its good recommendation algorithm to analyze and summarize users’ video preferences and playing habits through big data, and apply them to headline-made videos. They can even customize headline users’ exclusive homemade dramas and homemade variety shows according to the results of big data analysis and user preferences.

Compared with short video platforms, the advantages of long video platforms such as Youaiteng come from the copyright and IP resources of a large number of content creators. Youaiteng takes the lead in the segmentation field in the short video industry through its own areas of expertise. Strict supervision has, to some extent, "forced" the short video head platform to enhance the awareness of copyright, continuously expand the content map, and cultivate and expand the long video user base.

With the sudden outbreak of the COVID-19 epidemic, all the films for the Spring Festival in 2020 were withdrawn. On January 24th, Lost in Russia, directed by Xú Zhēng, announced that he would cooperate with ByteDance’s platform, and the "Headline System" short video platform (Tik Tok/Watermelon/Volcano) was broadcasted independently for free, which aroused the attention and heated discussion in the industry. Many people think that this is not only a symbol of headlines entering the long video and film industry.

With the expansion of users, long and short video platforms have already eroded each other. Short video platforms pay more and more attention to original content, and the competition for original content between long and short video platforms will become more and more fierce.

　　Today viewpoint

　　In the autumn of 2017, the cigar-shaped Oumuamua broke into the solar system and became the first interstellar visitor discovered and confirmed by scientists, which caused a lot of noise and turmoil in the scientific community. Although it is still unknown whether it is an asteroid, a comet or an alien spacecraft, American scientists have recently said that "flying immortals from outer space" like Omo Mo may not be special, and the elements of life on earth may originate from other star systems, which arrived on Earth by hitchhiking with interstellar visitors like Omo Mo Mo.

　　But at present, these are only assumptions. We need to "catch" more celestial bodies similar to Omo Mo for in-depth research with the help of large telescopes in the future to get the final answer.

　　"Omo Mo" is not special

　　The researchers said that "Omo Mo" is the first confirmed interstellar object we have observed in the solar system, but this does not mean that it is the first interstellar object to reach the solar system in history.

　　"We think, like ‘ Omo Mo ’ Such an object … … At any time, there will be one at a distance of one astronomical unit from the sun (the average distance between the earth and the sun is about 150 million kilometers). " At the "Breakthrough Discuss" conference held at the University of California, Berkeley last month, Bill Porter, head of the Department of Space Studies at the Southwest Research Institute in Colorado, said, "This actually has a very meaningful impact, similar to ‘ Omo Mo ’ Objects may bring life from one celestial body to another. "

　　This idea is called "panspermia)— — The theory put forward by scientists in the 1970s that life on earth came from space. At that time, the British physicist Lord kelvin believed that alien bacteria could reach the earth by comet or meteor and thrive on the earth; Other scientists believe that microorganisms can be embedded in dust particles and pass through galaxies, and they run from one planetary system to another through slight stellar radiation pressure.

　　Can provide heat insulation and radiation protection for microorganisms.

　　At present, the exact size of Omo Momo is still unknown, but researchers believe that its longest size is no more than 800 meters. The object will show "non-gravitational acceleration" when it is far away from the sun, which makes people speculate that "Omo Mo" may be some kind of alien spacecraft.

　　But the more common view is that the "intruder" of this solar system is very cold, and its strange movement is caused by the exhaust gas similar to a comet. When the comet approaches the sun, the ice on it will sublimate directly from solid to gas, forming a huge comet head and a long comet tail. When these gases are released, astronomers can use telescopes to study and determine their composition.

　　Karen Mitch, an astrobiologist at the Institute of Astronomy, University of Hawaii, said: "This tells us that ice can be preserved after such a long journey." Previous studies on comets and other small celestial bodies in our solar system show that objects like Omo have good heat insulation and radiation protection functions, which is good news for any microorganism that may "hitchhike". "Living organic matter can be found in ‘ Omo Mo ’ The interior is well protected. "

　　Astronomers have not found the star system that gave birth to Omo, so we don’t know how long ago Omo was ejected into the dark and cold interstellar dust. But Mickey said that it may have traveled through interstellar space for 10 million years or more.

　　Looking for the next interstellar object to study.

　　Of course, it is still unclear whether any hypothetical creature on Omo will survive the collision with the earth. Mickey said that this icy object hit us at a speed of 215,000 km/h relative to our planet. "This is a very high impact speed."

　　In this regard, Stern Sigurdsson, a professor in the Department of Astronomy and Astrophysics at Pennsylvania State University, said in another speech at the "Breakthrough Discussion" conference that "Omo Mo" and its "passengers" may be quite soft, so after hitting the earth, they may land relatively gently and disperse when they break into our atmosphere.

　　Sigurdsson said that the previous work of Ivey Laueber, director of the astronomy department of Harvard University, and others, as well as his own calculations show that in the nearly 4.6 billion years of history of our planet, about 100 celestial bodies like Omo have hit the earth. "So, we don’t know whether there is a biota inside one of these celestial bodies."

　　Laueber added that we don’t know where Omo is now. "Therefore, it is more meaningful to find the next interstellar object." The powerful large-scale weather measuring telescope (SST) is scheduled to take off from Chile next year and begin to observe the sky. When it runs "full of blood", it may find an interstellar object every month for our study.

　　In addition, scientists suggest that it is also possible that life reached the earth only a short distance long ago. Earthlike planets in our solar system exchange rocks quite regularly, as evidenced by the increasing number of Martian meteorites on earth. In fact, some researchers believe that life on earth may have started on the red planet, and a Martian stone reached the earth in a strong impact.

　　Of course, all this is just a hypothesis, and more scientific evidence is needed to reveal one of the ultimate puzzles of mankind — — Where we come from.

　　(Science and Technology Daily, Beijing, May 8 th)

　　Bitcoin’s "madness" in this round has been somewhat lasting.

　　On January 5, according to the data of Huobi.com, a domestic bitcoin trading platform, at 1: 10 am, the price of bitcoin broke through the historical high of 8,000 yuan three years ago, setting a historical record. As of 8: 45 on January 5, the highest price of bitcoin reached 8650 yuan, and the price increased by more than 260% within one year.

　　The British "Guardian" said that market analysts believe that the main driving force for this round of bitcoin price surge is in China — — In 2016, the RMB depreciated by nearly 7%, the worst performance in 20 years, which triggered a huge demand for Bitcoin.

　　The historical highest price of Bitcoin was 8,000 yuan on November 19th, 2013. A month ago, the price of Bitcoin was still hovering around 1000 yuan, and it tripled in a short time. However, this price fell after less than 1 minute, and then it bottomed out all the way, reaching a minimum of 933 yuan.

　　Compared with that rise, Bitcoin rose slightly steadily this time, from 2,351 yuan in early 2016 to 8,000 yuan in early 2017.

　　Zhu Jiawei, COO of Huobi.com, said that this round of 8,000 yuan market is very different from that in 2013: First of all, the current bitcoin transaction volume is not the same as that of that year. When the highest price of Huobi was 8,000 yuan in 2013, the weekly transaction volume was 393,000 bitcoins, with a weekly amplitude of 103%, which was very small and was greatly affected by funds; Now, when the price of bitcoin breaks 8,000 yuan, the transaction volume in the four days after Huobi Net Festival is 7.35 million bitcoins, which is 37 times of that year’s transaction volume. The price amplitude in the four days after New Year’s Day in 2017 is 15.95%, which is much more stable than that year.

　　In addition, Zhu Jiawei believes that after the application of Bitcoin is promoted, the price tends to be stable. Although Bitcoin rose by 260% from 2016 to 2017, it won the top spot among many investment varieties. However, in the whole year of 2016, according to the data of Huobi. com, the daily price of Bitcoin rose and fell by 10% or more in less than five days, while in 2013, the daily price rose and fell by about 10%.

　　For Bitcoin entering the bull market in the past year, Zhu Jiawei analyzed the reasons: First, the underlying technology blockchain of Bitcoin has been recognized by major banks and financial institutions around the world; Secondly, in early 2016, the central bank held a digital currency seminar to start studying digital currency and blockchain technology; This year, domestic mainstream investment products, including stock market, property market, gold, etc., performed poorly on the whole, while bitcoin rose very well, and funds turned to bitcoin investment channels; Bitcoin halved its output for the second time in July 2016, which also promoted market sentiment fluctuations and pushed up prices.

　　Xu Mingxing, founder and CEO of OKCoin, another bitcoin trading platform in China, analyzed this wave of gains: "According to the laws of the trading market, investment products will rise if they follow a long decline, and will fall if they rise for a long time. Judging from the cycle of Bitcoin, this price increase is a long-term cumulative result after the price peak in 2013. But it is investors’ confidence in Bitcoin that affects the price of Bitcoin for a long time. "

　　The US "Wall Street Journal" reported in May last year that some analysts said that the rise of Bitcoin was mainly driven by the demand in China market brought about by the recent RMB depreciation, and the two major bitcoin trading platforms in China — — Huobi and OKCoin— — At present, it constitutes about 92% of the total global bitcoin transactions.

　　Just as the speculators were ecstatic, the Financial Times "poured a pot of cold water", saying that the value of Bitcoin was zero.

　　"A trading intermediary is always ups and downs, then it is a useless currency. In fact, Bitcoin has all the characteristics of pyramid scams. It requires that believers continue to enter the market to push up prices, and this is based on the promise that more believers will join in the future, so the value of Bitcoin will be the same as that of all pyramid scams. Zero. " The Financial Times reported on January 4th that.

　　In China, bitcoin as a currency has never been recognized by the regulatory authorities. Five ministries and commissions, including the central bank, said in the Notice on Preventing Bitcoin Risks issued in December 2013 that although Bitcoin is called "currency", it is not a real currency because it is not issued by the monetary authorities, and it does not have monetary attributes such as legal compensation and compulsion. In nature, bitcoin should be a specific virtual commodity, which does not have the same legal status as currency, and cannot and should not be used as currency in the market.

How to troubleshoot RAID 5 in the server

　　Due to the continuous progress of technology, different types of servers have different treatment methods after RAID 5 failure.

　　At present, the network topology structure of large-scale application programs generally adopts C/S structure or B/S structure, and at least one server with a large database needs to be placed in the central computer room. Considering the security and reliability of the server, RAID (Redundant Array of Inexpensive Disks) is usually used for redundant backup of the server’s disks. Among them, RAID 5 array level is parity disk array without independent parity disk, which adopts data blocking and independent access technology, can process multiple access requests in parallel on the same disk, and allows any hard disk in the array to fail.

　　In practical application, due to some inevitable objective reasons, some array failures may occur. The most common situation is that the hard disk automatically goes offline, and the online status is displayed as DDD (invalid disk drive), and the hard disk has physical or logical failure. If it is a physical fault, only the hard disk can be replaced; If it is a logical fault, it can be repaired by targeted technology to restore the online state of the hard disk, continue to maintain the striped distribution of the hard disk data in its original array, and continue the consistency of the data storage system.

　　However, the data recovery of some old HP servers (such as HP LH6000) is different from that of new HP servers (such as HP ProLian series servers). Therefore, different servers handle RAID 5 failures differently. I have been in contact with the data failure of RAID 5 array card caused by unexpected power failure of two servers, and solved the problem by adopting different strategies.

Fault repair

　　One is HP LH6000 server, and four 18GB hard disks are made into RAID 5 disk array, and its array card is NetRaid. The other is HP ProLian ML370 server. Four 146GB hard disks are made into RAID 5 disk array, and its array card is Smart Array 642 with Hot Spare hard disk. Both operating systems are Window 2000 and the database is Server 2000.

　　The fault of HP LH6000 is as follows: one hard disk is flashing red light, and the machine is still running normally, but it will not be long before the system can not run normally, and then it is found that the red light of another hard disk is flashing.

The solution is as follows:

　　1. start the server, and press Ctrl+M to enter the NetRaid management program when self-checking to the array. Check the array information and find that the hard disk status is Failed, and use the modified configuration to forcibly set a hard disk to OnLine. Restart the server, the hardware self-check before entering the system is invalid, and the startup fails.

　　2. Start the server, and press Ctrl+M to enter the NetRaid management program when self-checking to the array. Select the disk array, manually Fail the hard disk that was originally hung OnLine, and then manually set another Failed hard disk to OnLine, and restart the server to enter the system.

　　3. After checking that the system and database are running normally, enter the array configuration tool and manually set the Failed hard disk to Rebuild, and then restart the server after 100% reconstruction. All arrays and systems are restored to their original state.

　　Another server running ERP system (HP ProLiant ML370) is configured as a RAID 5-level disk array by four 146GB hot-swappable hard disks through RAID cards (Smart array array cards). One of the hard disks suddenly broke down during operation. Server RAID 5 automatically enables the Hot Spare hard disk to logically replace the damaged hard disk. The data access task of the whole hard disk still runs completely in the original reading and writing process sequence, and the application program and database have no influence.

　　Check the hard disk status through the ACU tool that comes with HP, and find that the hard disk with red light warning is offline. If there are two red lights on Raid 5 in HP ProLiant server, it indicates that the system has crashed and the database cannot be accessed, but the system will not shut down automatically. When the second hard disk is red, the data can’t be recovered by conventional means, so we have to pay a professional third-party data recovery company to recover the data.

　　Therefore, for the old HP LH6000 series servers, the array design is quite different from that of the current HP ProLiant series servers. As far as the operation method is concerned, there are many options for the array operation method of HP LH6000 server, including deleting the array again and rebuilding it after the array fails, and the initialization is also manually selected. However, the initialization of HP ProLiant series server array is automatically performed in the background after the array is configured, so the ProLiant series server cannot reconfigure the array after an array error.

　　The HP LH6000 server will cause the disks in the array to be disconnected for other unexpected reasons, so the maintenance personnel can manually choose Online or Offline, Rebuild, etc. to restore the data. However, the current HP ProLiant series servers will no longer have the phenomenon of disk disconnection in the array like the old servers, so when the hard disk is red, it is basically damaged and needs to be replaced. Of course, you can choose to Rebuild the hot-plug hard disk and see if the hard disk can be used for a while.

Do a good job of technical backup

　　From the above two examples, it can be seen that the troubleshooting of Raid 5 disks of servers of the same brand and different series is different because of their different embedded technologies. But after Rebuild the data, the data was saved, from which the following experiences can be drawn:

　　We believe that any advanced technical means is not foolproof. If you want to ensure data security, you must do a good job of backup, and it is best to do a remote backup of the database once a day. Spare at least one new hard disk. It should be pointed out that the hard disk that joins the array must be greater than or equal to the capacity of the failed hard disk.

　　If conditions permit, the array creation scheme of "RAID 5+ hot spare" is recommended. This way, we have two chances to replace the hard disk before the data is lost. For general applications, only RAID 5 is needed, which can provide data access performance, reliability and maximum disk space at the same time.

　　Administrators must always observe the status of the array, including the yellow warning light of the disk array and the drive status in the management software. Trouble shooting in time. No matter what level of array, data backup should be done before troubleshooting.

Implementing the innovation-driven development strategy and promoting "mass entrepreneurship and innovation" is a major deployment made by the CPC Central Committee. As for starting a business, we have heard the story that some entrepreneurs often raise millions of dollars and get rich overnight. Is it really that easy to start a business? It is also said that the success rate of starting a business is less than 1%, and a startup enterprise may face death if it is not careful. Is entrepreneurship really that terrible? The series report "Entrepreneurship on the Road" tells the ups and downs of these young people’s entrepreneurial stories.

　　CCTV News:The National Health and Wellness Commission held a press conference on December 2 to introduce the prevention and treatment of respiratory diseases in winter and answer media questions.

Xinhua News Agency: Vaccine has played a key role in the prevention and control of influenza. At present, influenza has entered the high season. Is it too late to vaccinate now?

Wang Dayan, Director of National Influenza Center, Institute of Virology, China CDC:Among the prevalent respiratory diseases, influenza, COVID-19 and pneumococcal infection all have corresponding types of vaccines. The influenza vaccine has been used in the world and China for decades. Scientific research and vaccination practice have fully proved that the influenza vaccine is safe, effective and a mature vaccine. Influenza vaccination can effectively reduce infection, even if it is infected, it can also reduce the incidence, and even if it is infected, it can also reduce the severity of the disease.

At present, it is the high season of influenza, and it is still effective to vaccinate people who have not been vaccinated with influenza before. It is recommended that you vaccinate with influenza as soon as possible. Here, I especially point out that people over 6 months can be vaccinated with influenza, especially for high-risk people such as children, the elderly and patients with chronic diseases. After being infected with influenza, the risk of severe illness is higher. Vaccination with influenza can effectively reduce the risk of developing into severe illness and death. I hope everyone will actively vaccinate.

Practice at home and abroad has proved that the use of vaccine is one of the most economical and effective preventive measures, and the vaccine is safe. As long as it is vaccinated in professional institutions as required, it can have good results, especially for the elderly and children, and should actively vaccinate against influenza to ensure the normal pace of life and study.

Actress Aya Sugimoto was recently invited to shoot a group of public service advertisements for PETA, an animal protection association. On the 17th, she took a formal photo shoot in a studio in Tokyo.

　　Although she was used to nudity in filming, Aya Sugimoto felt a different sense of tension that day. Only one piece with the words "Fur? It’s better to be naked. "The advertisement board covers her chest. She said," So far, I feel naked is the feeling of wearing another suit, but this time I have a different sense of tension. I seem to have taken off all my clothes. " Having said that, the actress, who is famous for her sexy and erotic lines, still showed a provocative and dangerous expression when facing the camera. "I stopped wearing fur two years ago, hoping I could face the eyes of those dead animals." It seems that Erotic Queen still has a positive attitude and decisive action in environmental protection. I believe this is also the place that PETA invited her to appear in this group of advertisements.

　　On the afternoon of April 10th, General Secretary of the Supreme Leader visited Yazhouwan Seed Laboratory and Sanya Ocean Research Institute of China Ocean University successively in Sanya, Hainan Province, to learn about Hainan’s support for seed industry innovation and the development of marine science and technology.

　　Standing at a new historical starting point, "China’s economic and social development and improvement of people’s livelihood need scientific and technological solutions more than ever before, and it is even more necessary to enhance the first driving force of innovation."

　　Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has visited the frontier of scientific and technological innovation for many times, and expounded the great strategic significance of scientific and technological innovation with vivid metaphors for many times.

　　"This ‘ Gold pole ’ I understand it as agricultural modernization. "

　　General Secretary of the Supreme Leader once told such a story. At that time, he was hungry and asked the people around him, what kind of life do you think is the best, and what are the specific goals? Try harder and think boldly about what is higher. "Their answer is — — I will carry a gold pole when I go up the mountain to work in the future! " "This ‘ Gold pole ’ I understand it as agricultural modernization. " The words of the Supreme Leader’s General Secretary contain true feelings.

　　"To solve the problem of eating, the fundamental way out lies in technology." The "golden pole" bears the farmers’ "money bag" at one end and the people’s "rice bag" and "vegetable basket" at the other. Agricultural modernization is based on seeds. "A seed can change a world, and a technology can create a miracle." The General Secretary of the Supreme Leader pointed out that we should make up our minds to develop the national seed industry, pay close attention to cultivating excellent varieties with independent intellectual property rights, and ensure national food security from the source. During this inspection in Hainan, the General Secretary made a special trip to Yazhouwan Seed Laboratory. Yazhouwan Seed Laboratory, established in May 2021, as a public scientific research platform built by Sanya Yazhouwan Science and Technology City, relies on and serves the national Nanfan Scientific and Research Breeding Base, and is guided by seed innovation and seed industry development, helping the high-quality innovation and development of seed industry in China.

　　General Secretary of the Supreme Leader profoundly pointed out, "Only by combining scientific and technological achievements with national needs, people’s requirements and market demand and completing the triple jump from scientific research, experimental development and popularization and application can we truly realize innovation value and realize innovation-driven development."

　　At the symposium of scientists in September 2020, the general secretary pointed out that "accelerating scientific and technological innovation is the need to realize people’s high-quality life" and "in order to meet people’s yearning for a better life, more scientific and technological innovations involving people’s livelihood must be introduced". It is on this occasion that the general secretary put forward new requirements for the vast number of scientists and scientific and technological workers to "face people’s lives and health." During the "Thirteenth Five-Year Plan" period, China has made a number of major scientific and technological achievements in the field of people’s livelihood science and technology. Integrated whole-body positron emission/magnetic resonance imaging equipment, rice breeding accelerators in unmanned plant factories and other scientific and technological innovations for people’s lives and health have been continuously unveiled and applied to a better life.

　　"Scientific and technological innovation, like a lever to incite the earth, can always create unexpected miracles."

　　In June, 2014, at the 17th Academician Conference of China Academy of Sciences and the 12th Academician Conference of China Academy of Engineering, General Secretary of the Supreme Leader pointed out: "Scientific and technological innovation, like a lever to shake the earth, can always create unexpected miracles. The development of contemporary science and technology fully proves this process. "

　　Scientific and technological innovation makes the deep sea no longer mysterious. In April, 2018, General Secretary of the Supreme Leader visited the Institute of Deep Sea Science and Engineering of China Academy of Sciences in Sanya, Hainan, to learn about China’s first 10,000-meter seabed exploration in the Mariana Trench, and went into the exhibition area of deep-sea exploration equipment with great interest to see all kinds of deep-sea diving high-tech equipment.

　　Technological innovation makes space no longer far away. Just last month, the second class of "Tiangong Classroom" was held in China Space Station, and the astronauts of Shenzhou XIII gave another wonderful space science class. During more than 170 days of space flight, three astronauts, with the support of ground technicians, carried out a number of scientific and technological experiments and application projects, setting many "firsts" and "firsts".

　　Scientific and technological innovation is the strategic support to improve social productivity and comprehensive national strength. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has made a major strategic choice of "innovation must be the first driving force for development" and implemented the innovation-driven development strategy.

　　"Life Gate", "Bull’s Nose", "Heaviest Weapon of the Country", "Fixed Sea Needle" and "Unique Weapon" … … Nowadays, China has started a new journey of building a socialist modern country in an all-round way, and the position of scientific and technological innovation in the overall development of the party and the country is more prominent.

　　"Innovative achievements should benefit the whole world, and should not become treasures buried in caves."

　　In November 2019, when the Chairman of the Supreme Leader met with foreign representatives attending the 2019 Innovation Economic Forum, he pointed out that "no country can become an independent innovation center or enjoy innovation results exclusively. Innovations should benefit the whole world and should not be a treasure buried in a cave. "

　　Fungus and grass technology, which has been popularized in more than 100 countries around the world, is a dazzling treasure out of the cave. With the long-term concern of the Supreme Leader, the fungus-grass technology of "replacing wood with grass" has gone out of China from Fujian to the world, which has played an important role in promoting local development and people’s well-being, and has been widely welcomed by developing countries.

　　"China is willing to work with all parties concerned to continue to contribute China’s wisdom and China’s plan for the implementation of the UN’s 2030 Agenda for Sustainable Development, so as to make mushroom technology benefit the people of developing countries ‘ Happy grass ’ ！” In September last year, the Chairman of the Supreme Leader pointed out in his congratulatory letter to the 20th anniversary of foreign aid to fungi and grasses and the International Cooperation Forum for Sustainable Development.

　　The world today is experiencing a great change that has never happened in a hundred years, and the domestic and international environment facing China’s development has undergone profound and complex changes. In the face of fierce international competition and against the background of rising unilateralism and protectionism, General Secretary of the Supreme Leader is far-sighted: "Scientific and technological achievements should benefit all mankind, and should not be a means to restrict or contain the development of other countries."

　　China’s scientific and technological innovation, not alone, nor narcissistic. "Promoting sustainable development through scientific and technological innovation has become the only way to solve some important global issues of concern to all countries." "We have expanded open cooperation in the field of science and technology, actively participated in solving major challenges facing mankind, and worked hard to promote scientific and technological innovations to benefit more countries and people." … … China’s scientific and technological innovation has conveyed China’s wisdom and contributed to China’s plan, which is promoting mutual benefit and sharing, unity and cooperation among all countries, creating a bright future together, and making continuous progress towards building a community of human destiny.
