　　[car home Information] March 2 was a magical day. On the other side of the ocean, Musk talked about secret ambitions on Investor Day; Li Xiang, CEO of China and LI, spent five pages of PPT at the media communication meeting and shared it for two hours. In view of all the contents he shared, this paper only extracts the product information that everyone cares about, focusing on the follow-up product planning, autonomous driving progress and intelligent cockpit.

Some core messages:

1. Ideal to be a pure electric product, and still adhere to brand positioning: the luxury electric vehicle preferred by the family can be at the same price as the extended-range product.

2. NOA, the ideal city, was pushed to Max users in the fourth quarter.

3. Ideally, 8295 chips will be introduced, and L7/L8/L9 will support the replacement of 8295 chips.

■ What is the ideal pure electric vehicle?

　　Friends who care about the ideal know that the ideal is not a dead-end extended range, but also pure electricity, and will make extended-range products until 2030. Unfortunately, at this communication meeting, we still don’t know what the ideal first pure electric product is. LI’s classmates told me that it is a "form you haven’t seen before", and the spy photos that have flowed out at present show that it may be an MPV. But obviously the ideal is not only a pure electric product, combined with the information of the financial report communication meeting at the end of February,The ideal pure electric product has a product sequence similar to the L series, which meets the needs of home users in the price range of 200,000-500,000.Of course, no matter what body shape it is, it is bound to have a big impact on the pure electric products that are mainly used at home at this stage.

"ideal pure electric MPV spy photos"

　　However, no matter what this pure tram is, it still adheres to the ideal concept of "luxury electric car preferred by the family". Therefore, friends who care about their families can rest assured that the ideal pure electric product will not suddenly go off course, and get a big super-run with a speed of 100 kilometers for 3 seconds, so just wait and buy it.

　　Li Xiang mentioned in his speeches everywhere that choosing extended range can solve two problems, one is battery cost and the other is energy supplement. Excellent manufacturers are trying their best to solve these two problems, such as Tesla’s extreme cost reduction and overcharging, and Weilai’s desperate efforts to build and replace power stations.

　　The cost of batteries remains high, either manufacturers lose money to earn money or consumers spend more money; It is inconvenient to replenish energy. Some people say that an ideal range extender with low technical content directly hangs the 800 VSiC that a manufacturer has worked hard to make, which is not rough.

　　Of course, we can’t say that the technology of 800V SiC is not good. In fact, the ideal pure electric vehicle is also this technology, and this technology is used to solve the above-mentioned cost and energy supplement problems.

　　In terms of cost, Li Xiang said that 800V pure electric products are not so expensive, and they can achieve the same price as extended range. He said that the battery of 100kWh can last about 600km now, but we can use 80kWh through 800V and SiC components. And let the cost drop by 30,000-40,000 yuan, and the money saved will of course be piled up in the comfortable and intelligent configuration that we like to see.

　　In terms of energy supplement, Li wanted to show a set of mode of household slow charging+urban fast charging (200kW)+ high-speed overcharge (480kW), and he also made the account clear. For example, a charging station with 480kW+3 250kW piles costs 1 million RMB, and 1,000 stations are built, which will be shared over five years, with an annual income of 2 billion, that is, 100 billion yuan.

　　However, some people question this set of accounting logic and the pressure of the power grid. As we are not experts, we will not analyze it indiscriminately. In short, we all know that the ideal is to replenish energy, and it will not be worse than other manufacturers.

　　Summarize the characteristics of ideal pure electric products: strong household attributes, the same price as extended range, and comfortable energy supplement. As for the time, although Li Xiang didn’t say it, according to the news in early February, it was off the assembly line in July and officially mass-produced in September.

　　By the way, L5 is a big satellite in LI. At present, there are only two information points that Li wants to talk about in Weibo, namely, the non-SUV form and the price range of 200,000-300,000. However, according to Li Xiang himself, the ideal L7/L8/L9 is just like an Apple mobile phone, except for the case. This is really keep real… Then the L6 (five-seat SUV within 300,000) and L5 are estimated to be quite different. The form of non-SUV is a supplement to the ideal product line. After all, you have to walk on two legs these days.

■ NOA internal test of the ideal AD Max open city in the fourth quarter.

　　 It is not a new force to not engage in autonomous driving these days. In the new year, everyone began to roll up the city NOA. The ideal plan is to open the internal test of early bird users in NOA city on the ideal AD Max in the fourth quarter of this year. It should be noted here that the AD Pro version does not support urban NOA, but the actual experience of high-speed NOA is basically the same as that of the Max version, so you must pay attention when buying a car.

　　Li Xiang believes that electric vehicles that cannot realize NOA in cities can only be called "electric vehicles", not "smart electric vehicles". The city NOA is actually similar to the high-speed NOA realized by many manufacturers at present, except that the scene is changed to the city, and the automatic driving from point A to point B is realized in the city without human takeover.

　　From the second half of 2022, the city NOA has taken shape. Tucki, the pioneer of autonomous driving, pushed CNGP (city NOA, called by different manufacturers) on P5 in September 2022; Extreme Fox Alpha S HI and Huawei, WEY Mocha and Millie Zhixing have all realized this function.

"Tucki city navigation aid"

　　At present, there are various factions and ideas under NOA in the city. For example, whether the high-precision map is used or not has undergone a series of changes and iterations. Previously, Tucki was a high-precision map player (it seems that he hasn’t completely given up now, and He Xiaopeng also proposed to speed up the review process of high-precision maps at the two sessions), and he also has Grade B mapping qualification. But now most players are gradually turning to the route of "emphasizing perception and ignoring maps", and in terms of perception, there are also pure visual Tesla and radar cameras.

　　Under the mode of relying on high-precision maps, the city NOA will be limited to cities that allow surveying and mapping. For example, the city NCA of Polar Fox is still limited to Shenzhen and Shanghai. Li Xiang said that the ideal will not demarcate the city NOA one by one like the traditional model, but will promote NOA in many cities based on the big model and BEV (Bird’s Eye View, not electric cars). This is also the so-called software 2.0 era.

"Tesla’s perceptual process"

　　　BEV perception is to establish a bird’s-eye view of camera images from multiple perspectives and then perceive them, and cooperate with Transformer algorithm to make autonomous driving more cattle. In the case that Tesla, a pioneer, explores the road for everyone, domestic car companies have also started this set of operations. Li wants to predict that these companies using the Orin computing platform will basically deliver the earliest NOA； for testing in the fourth quarter of this year; By the end of the year, most head enterprises can achieve the level of Tesla at the end of 2011, and by 2024, everyone can generally achieve the level of Tesla in North America at the end of 2022 and the beginning of 2023.

　　In the end, the city NOA does not need to become fully autonomous driving, but it can help drivers improve their experience when there is traffic jam every day. If more than 60% or even more than 80% of the cars in the city can be driven by this function, and the safety is no problem, it will have a huge change. Just as consumers buy a 20-30-story building, it is a fundamental difference whether there is an elevator or not.

　　Judging from the current situation, autonomous driving also requires manufacturers to continuously educate users to use it, so that users can’t live without it. The utilization rate of assisted driving in LI is over 13%, and the utilization rate in high-speed scenes has exceeded 50%. According to the Spring Festival travel data released by Weilai, its total mileage is 276,699,061 kilometers, and the total mileage of NIO Pilot is 39,135,610 kilometers, about 14%.

　　But judging from the situation of G9, another new force in Tucki, it has little effect on assisted driving. I think that autonomous driving is indeed the right way, but this road has a long way to go. Perhaps next year, with the landing of NOA in the city, the utilization rate of automatic driving assistance can be significantly improved.

■ Don’t worry, the old owner can upgrade 8295.

　　LI is known as "creating a mobile home", so they collectively refer to the things in the car as intelligent technology, and this space will be the largest, most comfortable and most intelligent. Everyone holds a screen at home, so be sure to put more screens in the car. In this regard, everyone is most concerned about getting on the 8295 chip.

　　The computing power of Qualcomm 8295 chip is eight times that of 8155. According to the current rhythm, the ideal may be the same as that of Jidu, and 8295 will be delivered in the fourth quarter of this year, and the ideal new product is expected to be released during this time period. Then the question is coming. What about the old L9/L8/L7? I believe that everyone has not forgotten the rights protection incident of Li ONE’s change before?

　　But don’t worry this time, the old car owner can change the 8295 chip, but the change and how much money are still under study. At that time, Zhu Yu, who spent 300 million yuan to upgrade the old car owner for free, was in the front. What would the ideal do? However, it should be noted that the ideal delivery volume is not comparable to that of Krypton in that year, so I suggest that the old car owners should have a bottom in mind first, and it may be more comfortable to lower their expectations in the future.

　　After getting on the bus, the 8295 has greatly improved the intelligent cockpit, supporting more screens, stronger 3D rendering ability and millisecond voice. Even due to its powerful computing power, even if NVIDIA’s autopilot chip dies, it can take over autopilot … At present, 8295 is still a piece of jade to be carved, depending on how the manufacturer empowers it. According to Jidu, at present, manufacturers have not fully utilized 8295, especially in the AI part. Just as the ideal is also very concerned about AI, we can look forward to how the ideal plays 8295.

　　In addition, the "ideal classmate" has changed from the elephant scheme to the ideal self-research, and has now evolved into a new generation of end-cloud integrated architecture, which can support the deployment of stronger and more complex algorithms in the car. In addition, the self-developed algorithm has also improved in voice and visual interaction. LI believes that a good voice assistant should be awake, quick in execution, accurate in recognition, able to understand everything and speak human words. That is, to improve perception, performance and recognition. Suppliers can no longer meet their needs, so they turn to self-research.

■ Where is the degree of "self-research"?

　　Next, we want to talk about "self-research". Tesla, the industry leader, has always been a leader in its self-developed chips; BYD, the king of China, is a moat for its self-developed and self-produced batteries, which can also be exported. Many car companies are also flaunting their own self-research on assisted driving, electric driving and engines. Where is the degree of "self-research"?

　　LI believes that self-research and self-control are two dimensions, and the proportion of self-research and self-control should be controlled at 25%-30%, which should not be too high or too low. In addition to fully meeting the needs of users, we should also ensure the landing of core technologies and the safety of supply chain. The direction of self-research of ideal core technology is all related to platform technology. Such as extended-range electric, high-voltage pure electricity, smart space, intelligent driving and EEA electrical architecture. There will also be some self-developed technologies such as silicon carbide functional modules and three-in-one motors on the pure level stage.

　　In terms of meeting the needs of users, for example, a "task master", the hardware and software of the task master can be called together. Li Xiang said, whether it is self-research depends on how many functions can be called in the task master. Some functions are not open to you by the supplier. Only you can call all the functions by self-research and combine them together.

■ Edit summary

　 　 Generally speaking, this paper only shows a small part of the ideal spring communication meeting. At this communication meeting, what Li wants to share is not only about products and technologies, but also a lot about companies, growth and entrepreneurship. It can even be said that if you want to start a business, you can also benefit from listening to this communication meeting.

　　In the first two months of the year 2023, the ideals are firmly in the top position of the new car-making forces. Obviously, the ideals still have big moves. So what level do you think LI can reach this year? Can you surpass the second-line luxury and challenge BBA? Welcome to communicate in the comment area. (Text/car home Xing Yueyang)

On March 5, 2024, Tropic Haze, the author of NS simulator "Yuzu", announced that it had reached a settlement with Nintendo, paid 2.4 million US dollars in compensation, stopped the subsequent simulator development and operation, and closed related websites.

Although many players complain that they wouldn’t use the simulator if it weren’t for the poor performance of NS machines. However, with the increasing awareness of copyright of players today, almost no one will refute the fact that "cracking games is illegal". "Game safety" is not only related to game manufacturers, but also closely related to players.

In fact, "game security" occupies a very important position in the game industry, and both players and practitioners have to deal with it almost every day. However, people usually don’t discuss it much, because "game security" has certain technical barriers.

In China, game security is almost directly linked to big factories. Because of the high cost of the security team, only big factories have enough financial resources. Large factories can make adequate plans before safety accidents happen, but on the other hand, small and medium-sized factories and independent developers, which also occupy most positions in the industry, often find it difficult to make appropriate responses when faced with various safety problems.

To this end, we found a high-tech security service provider FairGuard, which focuses on game reinforcement and anti-plug-in, and jointly found some game security cases that are close to gamers and practitioners and exposed to the public, and analyzed them from a professional perspective. We hope to let the public fully understand the specific operation, function and significance of game security.

In the field of game security, the worst professional but most common case type is DDoS attack (distributed denial of service attack). Because of its characteristics, small and medium-sized manufacturers and independent developers are more vulnerable to such attacks.

For example, the mobile game "Lesonas" launched on February 29th this year was attacked by DDoS organized by ACCN. The game had to be delayed for 1 hour, and many players reported that the game was stuck on the first day. Every time they read a line, it took more than 10 seconds to get to the next sentence. The main means of ACCN is to ask the project team to pay the "protection fee", otherwise it will keep attacking. Coincidentally, a mobile game with 7 digits for users is also attacked by DDoS at the service node. If it is not solved in time, the losses caused are incalculable.

The basic principle of DDoS attack is that the attacker uses a large number of "broilers" (computers remotely controlled by hackers) to occupy the bandwidth or CPU of the game server. If the game server is compared to a hotel, it is like the hotel just opened, and suddenly a group of people came to the door of the hotel to block the door, so that normal diners could not squeeze in, or this group of people entered the hotel and occupied most of the tables, and kept asking the waiter to order, but the waiter could not drive them away, and other diners were also affected.

In order to improve the efficiency of making money, it is often the studio with clear division of labor (such as ACCN organization) that uses DDoS attacks for extortion. Some people will "find" the games to be launched, and record the volume, type and online time of the games. Others will launch attacks according to these records, and there may be a special group of people who will be responsible for contacting various game project teams to confirm the payment.

Of course, these behaviors are illegal, but it is difficult for the project team to trace the source and pursue the responsibility. First, the members of such organizations may not be in China, and the server IP address has been transferred several times; Second, attackers generally use virtual currency transactions such as Bitcoin.

Every year, there are a large number of announcements about developers being blackmailed by ACCN organizations on game platforms such as TapTap. Although some platforms and publishers will provide protection services, for developers, "I am not afraid of thieves stealing, but I am afraid of thieves remembering". Attacks that come from the dark and I don’t know when will always be a hidden danger.

From the perspective of technical protection, DDoS attacks are only a matter of money. The volume of the game is different, and the traffic of the attack will be different. After all, the attack also needs to cost. If this degree is not balanced, it is likely to be a loss-making business.

The cost of "broiler" is low, but the cost of preventing "broiler" is high. For example, if an attacker uses "broilers" to attack the game server with 200G of traffic, then the game project team may have to buy 200G of public cloud (such as Tencent Cloud and Alibaba Cloud) resources for protection. The former may cost only a few hundred yuan, while the latter needs tens of thousands of yuan.

Attackers often take the lower value of the two as the "protection fee", but the project team can’t guarantee that the other party is honest. If the attacker "steals well" and only collects the protection fee once, the project team can barely accept it; But if the other party thinks you are a "fat sheep", they will blackmail you again and again. Many times, the project team dare not gamble, but they have no money to buy special protection services, so they can only pay the money.

In this regard, the relatively professional advice is to enhance safety awareness. Some developers don’t have the concept of prevention, and they often make up for it after the incident. However, the profit lost after the first DDoS attack is more than the money spent on early protection, which is not worth the candle.

According to the experience summarized by professional security service providers, the low-cost method is that as long as the project team buys public cloud resources or corresponding protection services in the first month of online, there will be basically no more studios to launch DDoS attacks. Small games can directly solve the problems that may cause great losses by spending less money.

Compared with DDoS, most people may know more about plug-ins and pay more attention to the impact of plug-ins on their own game experience.

Some plug-ins can monitor or directly modify game files, which will cause serious damage to the game ecology. FPS games have always been the hardest hit area for black-and-gray attacks because of their high category popularity, high cheating income and data storage in the client.

For example, in the "fake match" incident of the professional team "Crossing the Firewire" last year, the team invited the anchor team to play against the professional players in an open environment, and speculated through subsequent offline battles and whitewashing. Players find that the plug-in used by the anchor team is extremely concealed. If it is not because of the complete victory over the professional players, it is difficult for people to think of using the plug-in. In related reports, this kind of hanging is also called "anchor customized hanging".

There are two characteristics of "anchor custom hanging", one is just the right function castration, and the other is the anti-detection means with external intervention. The former is to make the anchor "icing on the cake" in technology and provide good enough "effect" in the game. For example, the "lock" function can only be triggered when the enemy appears and the sight is close to the enemy’s body. It is difficult for the naked eye to tell whether this tiny moving trace is from the plug-in. As for the latter-teams that do "anchor customization" services often sell special equipment together with plug-ins and put them in the equipment, which makes the official detection methods fail to some extent.

From the point of view of protection, game manufacturers often get plug-in samples first, and use the similar identification code in the plug-in samples to carry out preventive testing in the player’s game. If an official identification code appears in the background data of a player, then the official has the right to take measures, and generally it will not be blocked by mistake. However, the identification code of the anchor custom hanging is separate, and this process naturally doesn’t work.

However, even if the player’s behavior is not detected by the conventional process, the official can make manual judgment, which is based on the background environment and some behavior data of the player-reporting is meaningful at this moment.

If a player receives a large number of reports from other players, the official will check his background environment and behavior data, and give him a risk rating according to the results of the inspection. There are many dimensions of rating, generally to see whether the memory has been modified or whether it is in an unconventional environment (such as a virtual machine).

The security team will send the high-risk player ID to the project team, and the project team will decide the specific measures to be taken later. Some players may be "big R", charging a lot of money, and the direct title may cause legal disputes. If the manufacturer fails to produce enough "objective evidence", there will be a greater probability of losing the lawsuit. Therefore, some manufacturers will turn a blind eye to "big R", and for players below "small R", they would rather kill by mistake than let go.

Compared with anchor customization, "script" is less harmful, but it also has a direct impact on the balance and life cycle of the game. Scripts often appear in role-playing, card and strategy games. From the perspective of protection, scripts are directly linked to the studio, and MMORPG with economic system is the hardest hit area of the studio.

The role of scripts is to efficiently collect in-game resources and realize the obtained resources. In the long run, when the resources in the game are collected too much, the resources will become cheap, and players will tend to find a studio to buy resources instead of "earning" resources through their own game labor. In order to reduce costs, scripts often run on virtual machines or in the cloud. A studio with more than a dozen people may open thousands of scripts at the same time. In other words, in fact, the script is "endless".

Another phenomenon derived from scripts and studios is the "initial number". Chen Shiliu, the technical director of FairGuard, talked to me about this: nowadays, the second tour often requires players to exchange growth resources or roles through repeated work in the game. However, after the game has been in operation for one or two years, it is difficult for newcomers with self-built numbers to catch up with the progress of the game, and it is a common choice to buy "initial numbers" from the studio.

For example, on August 30, 2022, Nexon, the international service operator of Blue Archives, permanently banned 280,000 initial numbers, including not only those in the studio, but also many that have already flowed into the hands of players. This has caused "inflammation" among the players-players have taken lessons in the game and continued to play for a while, but after the manufacturer banned it, they did not provide compensation measures. Players will naturally question: Why didn’t the manufacturer deal with this violation immediately, but it took some time to deal with it?

Chen Shiliu told me that this is because the script does not modify the game memory data, but is just a fixed "simulated click", brushing the trumpet and licking the wool. Therefore, the security team needs to proceed from the risk situation of the equipment and combine the behavior judgment of the player after boarding the number. For example, players need to touch several fixed positions on the screen when doing daily work in a mobile game, but the time and operation logic of manual operation and script opening are different. In the case of background protection, the background will immediately detect the abnormal behavior of players and prompt that there is script risk. However, unlike FPS’s "anchor customization", the connection of the second tour is often "weak connection", and this behavior of hanging scripts and brushing resources cannot be reported. Game manufacturers can only observe it for a long time and regularly "one pot".

"One pot" means lag, so it is difficult to consider whether there are players in the account playing normally and whether there is recharge behavior. It is worth noting that while the players are "on fire", there are also many examples of the game rising due to the reduction of studios.

In Japan, the origin of the "initial number", many manufacturers have acquiesced in the existence of the initial number and formed a "symbiotic" relationship with the studio during their long "Yan Shang" career. Some games may be small in size and lack of newcomers, and the initial number even plays a role in saving some channels and announcing costs for developers. As long as it doesn’t directly affect the experience of other players, some developers will tolerate some behaviors that slightly modify the game memory, such as "variable speed hanging".

Other manufacturers adopt the attitude of "people don’t lift, officials don’t investigate". For example, the "ACT" plug-in of MMORPG Final Fantasy 14, if the player only uses its "damage monitoring" and "mechanism broadcasting" functions, the official will not take the initiative to intervene. After all, this plug-in has really improved the player’s game experience. But in principle, the game is not allowed to use plug-ins. If you take the corresponding test data to "police" other players, it will be officially banned.

Generally speaking, whether it is a plug-in or not, it is necessary to analyze the specific situation. For players, as long as the game is played according to the normal process, it will definitely not be banned. In this process, manufacturers need to reflect on whether their game design and version planning are unreasonable, and whether players must rely on some kind of soft plug-in (script) to get a good experience? If this is the case, it is not surprising that after the manufacturers take measures to crack down, they are "burned".

Strictly speaking, modifying the plug-in of game memory is also a part of cracking, but there are many more serious cases of cracking, and in the field of game security, anti-cracking is also the most important part.

In cracking, the most typical case is Legend. In the early years, "Legend" was cracked, and the source code was leaked. Some people deleted the source code with ulterior motives and added their own servers, which became a private server. In the field of black ash production, when a game is cracked, the cracked results will inevitably spread like a virus. When private servers can generate huge benefits, many people will ignore the law and start taking risks.

Under normal circumstances, game developers need to find the copyright party to request authorization to make genuine products. Private servers are like "tax evasion", which saves the step of paying money to the copyright party. There are many benefits in private servers, so there are fewer players playing genuine ones and the losses caused are incalculable.

Li Lei, marketing director of FairGuard, said that there are at least 20 billion industrial chains in the "Legend" mobile games, which are being attacked every year, but they just can’t be beaten.

Of course, "Legend" is because the code leaked and cracked too early, and there will be a situation of private servers. A more common "crack" is to make paid games available for free. This has also brought a series of chain problems: after some small games with in-house purchases are cracked, they will be sold online at low prices, causing losses to developers and operators; Embedding some programs in the installation package, collecting personal information of players during installation, and then selling the information for profit; Implanting illegal advertisements in the original internal purchase part to achieve the effect of imitating genuine products and making money; What’s more, it will adopt a "subscription system" to make profits systematically, far exceeding the bottom line that game security can tolerate.

However, there are fewer cases of cracking the whole game, while there are more cases of cracking encrypted resources. For example, the pictures, audio, text and other contents in the game are all "game resources". Before the game goes online, these resources need to be packaged and encrypted. Generally, the encryption methods of game manufacturers are relatively low, so they have to entrust a third party to further encrypt.

Li Lei mentioned that in recent years, the demand for content-based secondary games has suddenly increased. On the one hand, because the art cost of Second Tour is getting higher and higher, art resources have become one of the most important project assets, accounting for the bulk of the project cost. Once the art resources are cracked, it is very likely that there will be competing products with simpler playing framework but similar art content in the market soon-in the legal sense, the criteria for judging plagiarism and skinning of games are still strict, and developers may realize that competing products have cracked their own art resources, but it is difficult to find tangible evidence.

On the other hand, the cracking of resources means "spoiler", which will affect the ecology of the game community to a certain extent and may indirectly interfere with the version planning of the operators. For example, a second tour puts the character resources to be sold into the game in advance, which is cracked in advance and spread in relevant communities. This character will gradually lose its appeal to players in the information flow, resulting in a decrease in profit.

Li Lei highlighted the resource leakage incident of "Girl Frontline 2: Chasing and Releasing" last year, that is, the "Mrs. Raymond" incident. This resource leakage directly led to the subsequent public opinion outbreak, so that the developer scattered the network and lost the trust of the players. From the point of view of protection, it is inconceivable that with the size of "less than the top 2", there are security problems in game resources.

Li Lei said: "Generally, medium and large-scale games will contact professional companies to do encryption work six months before the start of testing. PvE or relatively’ stand-alone’ mobile games need to prevent situations like’ less top 2′, and PvP games should consider whether the cracked resources will be used to make plug-ins."

In fact, once the popular game resources are leaked, they will be spread quickly and widely. Although this behavior is illegal, it is difficult for game companies to hold the disseminators accountable. At this stage, what developers should do is to keep an eye on whether their project resources are used for sale or further malicious use to prevent the loss from expanding.

In the process of communication, we always mention a problem: some small manufacturers or independent developers easily ignore security issues, or have relevant knowledge, but lack experience in dealing with them. Although large and medium-sized factories have accumulated more or less relevant experience in the development process, they will sometimes "stumble" when faced with the rapid change and increasingly rampant black ash production.

In fact, whether it is reality or games, security has always been a big problem. As a developer, what you should do is to make a good plan in advance as far as possible to avoid problems and then find ways to solve them.

The so-called plan, buying "outsourcing services" from professional teams is an option, but not all. Developers should consider some design logic when making games: will it be used by criminals? Can you do some verification work from the server to improve the intrusion threshold of cracking and plug-in? In fact, these jobs don’t cost too much, but are more about ideas and "intentions". On this basis, if something goes wrong, we can avoid more losses to some extent by looking for a security team to deal with it.

For developers, such concepts and "intentions" are particularly important. If there is an excellent game, because the developer lacks security awareness, he doesn’t even know how to deal with the most basic DDoS attack problem when he goes online, which makes a team’s efforts for several years go up in smoke. This is not only the personal loss of the developer, but also the loss of the game industry.

　　BEIJING, June 5 (Xinhua)-According to foreign media reports, on the 4th local time, a light plane was suspected to have broken into the sky above Washington, USA, and was chased by American fighter planes at high speed. The light plane eventually crashed in Virginia, and the identity of the owner and crew of the plane attracted attention.

　　According to The Washington Post and The New York Times, this plane is a private business plane registered with a company named Encore Motors of Melbourne in Florida, USA.

　　Image source: The New York Times report screenshot

　　American media contacted the company’s operator, 75-year-old John Roupell, by telephone. He revealed that his daughter, two-year-old granddaughter, nanny and pilot were all on the plane.

　　John Roupell said he knew little about the crash. He said in a choked voice that if the plane loses pressure, "they will all fall asleep and never wake up again … … I don’t think they have found the wreckage yet. It drops at a speed of 20,000 feet per minute, and no one can survive in this situation. "
