Joss whedon will still direct Batgirl.

1905 movie network news Recently, the rumored rumor that joss whedon will no longer direct has finally been terminated. Warner officially announced that joss whedon is not only involved in the adaptation of the script, but also will continue to be the director of the film. From this point of view, the failure of the box office and word of mouth did not affect Warner’s plan. More importantly, Warner and DC are quite determined to adapt the "dark style". However, changes are ever-present, and it is not excluded that Warner will change directors before and during filming.

Batgirl is one of the most popular superheroes, but she has never had her own personal film, and some other characters in Gotham will appear in this film. Batgirl made her debut in Batman No.139 (April 1961), which was jointly created by Bill Finger and Sheldon Murdov. The first batgirl was Betty Kane, but the most famous batgirl was Barbara Gordon who appeared in 1967. As such, she appeared in the DC cartoon in 1967. She was the daughter of Gotham police chief James Gordon. She is usually allied with Batman, Robin and nightwing/Dick Grayson. "Bat Girl" will also be the second solo film featuring women in DC movies, after Gal Gadot. The most famous actor in the role of "Batgirl" was played by the late Yvonne Craig in the 1967-68 American version of Batman. In the film directed by joel schumacher, alicia silverstone, as a Batgirl, also appeared with George Clooney’s version of Batman.

Wei Deng directed Batgirl, which was a big move for him to move from Marvel movie universe to DC movie universe. He has previously written and directed and for Disney-Marvel Comics, and as a pioneer producer with women as the leading role, he has created American TV series Buffy the Vampire Hunter, Angel, Firefly, Doll Agent and. Weiden participated in Wonder Woman’s screenplay creation in 2000, but that project was not put on the market. Warner Bros.’ DC movie universe was opened in 2013, and was taken over by last year’s and, in addition, it also included Wonder Woman, Justice League and Jason Momoa. The producer’s current projects include the sequel film of Task Force X, the derivative film Gotham City Sirens led by "Ugly Girl" played by margot robbie in Task Force X, the independent film Batman directed by matt reeves, the independent derivative film led by "Black Adam" played by Dwayne Douglas Johnson in Shazam and Shazam, and the films featuring Flash and Ganggu.

There is no specific shooting plan for the film at present, but after determining the director, I believe that Batgirl will not be delayed for too long.

　　Beijing Youth Daily News (Reporter Jiang Ruojing) Before the end of next month, patients can make an appointment for the number source of the tertiary general hospital of the social office through the unified platform for appointment and registration in Beijing. A few days ago, the Municipal Health and Health Commission issued the "Notice on the Access of Social-run Third-level General Hospitals to Beijing’s Unified Platform for Appointment Registration". Social-run Third-level General Hospitals that normally open outpatient services to the public in the city can voluntarily choose to access the unified platform according to the actual situation. Hospitals in need can apply to the Beijing Municipal Health and Health Commission’s Medical Administration Office, and the Municipal Health and Health Commission will coordinate the hospitals to connect with the Beijing Unified Platform for Appointment Registration.

　　The Municipal Health and Health Commission stressed that the unified platform for appointment registration in Beijing adheres to the principle of public welfare service, and the appointment registration service provided through the unified platform shall not charge the appointment registration service fee. At present, the unified platform for appointment and registration in Beijing provides appointment and registration services for 147 secondary and tertiary public hospitals in Beijing.

　　The Municipal Health and Health Commission requires that the social-run tertiary general hospitals that are included in the platform should realize the full-number, full-number, full-source open reservation, and focus on ensuring that key departments and characteristic departments with large demand from the masses reserve the number of sources; Provide various forms of appointment services, including unified platform telephone appointment and online appointment services, as well as inter-clinic appointment, on-site appointment and community referral appointment; The first outpatient consultation is registered according to the department and title, and the patients who return to the clinic can be registered by the doctor through the appointment of return visit; The registration service provided by the hospital on the unified platform for appointment registration should be reserved for 3 months; Strengthen real-name registration system’s appointment registration and medical treatment, and verify the patient’s real name identity in triage and medical treatment; The appointment shall be made in different periods, and the appointment period shall be exactly within 30 minutes, and the number of doctors visiting in the morning and afternoon shall be reasonably allocated to increase the number of doctors visiting in the afternoon.

　　The Municipal Health and Health Commission requires that all hospitals should strengthen the overall management between the unified platform and other forms of appointment sources in the hospital. According to the appointment needs of patients in our hospital, the number and proportion of different numbers and different appointment methods should be adjusted in a timely manner, and patients should be guided to use the appointment method through the number source delivery mechanism. At the same time, it is necessary to do a good job of service connection with the unified platform, and reasonably divide the professional or specialist source categories uploaded to the unified platform according to the principle of not naming names, so as to ensure the accuracy of patient appointment and treatment.

　　Each hospital outpatient service should be equipped with an appointment consultation desk, equipped with corresponding service facilities and equipment and standardized, clear and easy-to-understand service signs; To strengthen the management of doctors’ visits, doctors should have examination and approval procedures and make-up requirements when stopping their visits, and timely arrange doctors with the same professional title to make up for their visits. For patients who have successfully made an appointment through the unified platform, according to the system of no roll call, the hospital should ensure that they see a doctor within the appointment time. Hospitals should also strengthen the education and training of medical staff, do a good job in making appointments for diagnosis and treatment services and emergency handling, and cooperate with Beijing Unicom to do a good job in training telephone booking service personnel on the unified platform to ensure service quality.

　　The Municipal Health and Health Commission said that all social tertiary general hospitals need to complete the access to the unified platform before the end of August this year. It is understood that the unified platform for appointment registration in Beijing is the official appointment registration channel designated by the Beijing Municipal Health and Health Commission. The platform does not provide the same-day appointment service. Users can make an appointment to access the number sources of most departments of the unified platform hospital from the next day to three months. The unified platform does not make an appointment by name according to the hospital, department, title and specialty. The specific appointment registration period and source information shall be subject to the 114 service telephone inquiry and website publicity.

The Russian military "dagger" hypersonic weapon system successfully completed the test in the Arctic, and the US Navy began to test unmanned sailboats in the waters near Jordan … At the end of the year and the beginning of the year, military powers such as the United States and Russia made frequent moves in the research and development of new weapons and equipment. After a little combing, it is not difficult to find that in recent years, with the continuous progress of global scientific and technological level, a large number of cutting-edge technologies have been applied to the military field, a new round of world military scientific and technological revolution is surging, and the form of war is quietly changing.

Hypersonic weapons have developed rapidly

Hypersonic weapons mainly refer to weapons based on hypersonic flight technology, which fly at more than 5 times the speed of sound, including missiles, bombers, reconnaissance planes and so on. This new weapon, which is known for its quickness, is considered by many military experts to change the future war mode to some extent. In recent years, the United States, Russia and other world military powers have launched fierce competition in the field of hypersonic weapons, launched a number of hypersonic weapons research and development projects, and some projects have made major breakthroughs.

Russia is in a leading position in the field of hypersonic weapons. As early as the late 1980s, the Soviet Union began to develop the hypersonic cruise missile code-named "X-90". At present, there are three kinds of hypersonic missiles owned by Russia, namely zircon, dagger and pioneer. Among them, the "dagger" hypersonic missile has a speed of up to Mach 10, which is mounted and launched by MIG -31 fighters. It can carry conventional warheads or nuclear warheads and is the first hypersonic weapon put into use by the Russian army. The speed of "Pioneer" hypersonic intercontinental missile exceeds Mach 20, which is enough to easily penetrate the air defense and anti-missile network carefully constructed by opponents. At the end of 2019, the first land-based "Pioneer" missile regiment of the Russian army joined the combat duty. "Zircon" is Russia’s first sea-based hypersonic cruise missile. It was successfully tested in October 2020 with a flight speed of Mach 9 and can be launched from a warship or submarine.

America also attaches great importance to hypersonic weapons. At present, the US military services are developing hypersonic weapons, mainly including the navy’s "conventional fast attack" hypersonic glider, the army’s "long-range hypersonic weapon", the air force’s AGM-183 "air-launched rapid response weapon" and "hypersonic attack cruise missile". However, the development of US hypersonic weapons is not smooth. In 2021, the US Air Force conducted three test launches of new hypersonic missiles, all of which ended in failure.

In addition, Japan, South Korea, India and other countries also have their own hypersonic weapons development plans and projects. It can be predicted that in the field of hypersonic weapon research and development, the situation of fierce competition among countries will become more and more obvious.

Artificial intelligence technology is widely used.

Artificial intelligence is one of the core technologies leading a new round of military revolution. In recent years, in order to seize the commanding heights of military science and technology, major countries have promoted the application of artificial intelligence technology in the military field while upgrading the research and development of artificial intelligence to a national strategy.

The United States is the first country to develop artificial intelligence technology and apply it to the military field. At present, the Advanced Research Projects Agency of the U.S. Department of Defense has launched the "Next Generation Artificial Intelligence" project, which mainly includes: promoting the technical update of key business process automation of the Department of Defense, improving the adaptability and reliability of the artificial intelligence system, enhancing the security and flexibility of machine learning and artificial intelligence technology, and innovating the algorithms and applications of the next generation artificial intelligence. At the same time, the US military has incorporated the development of artificial intelligence technology into the information plan of the Ministry of National Defense. According to reports, the US Navy EA-18G Growler electronic warfare aircraft has the ability to counter the enemy’s unknown radar due to the use of machine learning algorithms and other technologies.

Russian military artificial intelligence technology has been tested in actual combat. In the battle to help the Syrian government forces fight against the rebels, the Russian army used combat robots, drones and automated command systems. At present, the artificial intelligence marine robots independently developed by Russia include "Platform -M" and "Argo", which can perform tasks such as patrol, reconnaissance, demining and close fire support. In addition, the Russian army has also developed a robot that looks like a military dog and can run quickly, which is used to undertake tasks such as transporting ammunition supplies to the line of fire.

Britain, Germany, Israel and other countries have also taken artificial intelligence technology research as the focus of national defense construction. Britain claims to have developed a military robot called Homo sapiens. Germany’s Typhoon fighters have successfully connected with remote control vehicles. The Israeli military is developing intelligent tanks, which can plan tasks independently, drive automatically and use weapons automatically.

Unmanned combat weapons are in the ascendant

In today’s era, a new round of world scientific and technological revolution is developing rapidly, and the form of war is accelerating to intelligent evolution. In order to win the future war, major countries have accelerated the development of unmanned combat weapons and actively explored man-machine cooperative warfare methods.

According to the plan of the Russian Ministry of Defense, the Russian army is setting up the first unmanned combat unit composed of attack robots. The unit includes five sets of Uranus -9 robot systems and 20 unmanned combat vehicles. Uranus -9 is a multi-functional combat platform, equipped with 2A72 30 mm automatic artillery, 7.62 mm machine gun, anti-tank missiles and other weapons. At present, the Russian army, navy and air force have all installed unmanned combat platforms. Every division and brigade-level unit of the Russian Army has a drone company, and the Russian Northern Fleet has a drone regiment.

Most of the US Army combat units at all levels have UAV units. The US Navy is implementing the "Ghost Fleet" plan and preparing to build a force including 10 unmanned ships. At present, the US Navy has completed the twin-boat test of two unmanned ships, the Wanderer and the Ranger. These two ships will be equipped with Mk41 missile vertical launch system or Mk57 advanced vertical launch system. According to a guidance document issued by the US Navy in early January this year, medium and large unmanned surface combat ships and their formations will be the focus of their future development.

France, Britain and other countries are also striving for breakthroughs in the research and development of unmanned combat weapons. The British Ministry of Defence plans to start manufacturing the first unmanned combat aircraft in 2025. Equipped with missiles and electronic warfare equipment, the fighter will become the first unmanned fighter in Britain to shoot down enemy aircraft and resist the threat of surface-to-air missiles. The British Ministry of Defence claims that this unmanned aerial vehicle can find and avoid the enemy’s air defense system, and can continue to perform tasks even in the case of cyber attacks.

Original title: The measured performance of the diskless system in Internet cafes is 60% worse than that of different systems under the same configuration.

　　[PConline gossip]After returning from the visit to Zhongshan, our PConline cafe visiting team has always had a doubt. How is the development of Internet cafes in a big city with more brutal competition and rapid changes? Will the development be more advanced? With these doubts, we were lucky enough to visit Bayou Internet Cafe and its owner, Mr. Ouyang, located in Gangding, Guangzhou. Next, the PConline Internet Cafe Visiting Team took everyone into Bayou Internet Cafe to uncover the secrets of all aspects of the Internet Cafe. In this issue, we will mainly continue the previous test of the diskless system in Internet cafes, and see what the difference is between it and the common system with the same computer.

This is the past content of our Internet cafe visit series. Interested friends can click on the portal below to watch!

[Secret of Internet Cafe You Don’t Know] No.4: The owner of Internet Cafe revealed himself: Why did I spend 1 million to modify water cooling?

　　Bayou Internet Cafe is located in Gangding, Tianhe District, Guangzhou. Gangding is a relatively prosperous area in Guangzhou. Digital enthusiasts who live in Guangzhou should know that Gangding is the "holy land" of computer hardware and digital accessories in Guangzhou, where Pacific Digital Plaza, Tianhe Computer City and Bainaohui are concentrated. When the PC industry was brilliant, it was once the most influential computer hardware store in South China. Nowadays, although consumers prefer to buy computer hardware online, it is still the most important place for Guangzhou people to buy computer hardware and digital products offline. In addition, there are Jinan University and South China Normal University around Gangding. As we all know, students are a very noteworthy consumer group, which also affects the business direction of Gangding, a local shop. Mr Ouyang and his partners started the Internet cafe business in this digital place.

　　The business style of offline shops has always been determined by the attributes of the consumer groups living nearby. Because of the geographical location, the target audience of Bayou Internet Cafe is the consumer groups with strong spending power and high requirements, such as nearby college students. Therefore, Bayou Internet Cafe attaches great importance to the design of the store environment. Mr. Ouyang revealed that although most consumers of Internet Cafes are for e-sports games, they also have different needs, so he divided the various areas of Internet Cafes.

　　The overall environment of Internet cafes will feel like a coffee shop, which is completely free from the dirty, chaotic and poor phenomenon of previous Internet cafes. Besides, smoking is also prohibited in Internet cafes, and the overall atmosphere is more comfortable and casual.

　　The front desk of the Internet cafe is a water bar. Mr. Ouyang revealed that 30~40% of the income of Internet cafes now comes from value-added services, which is also the biggest difference between Internet cafes and Internet cafes in operation.

　　Near the bar is a leisure and entertainment area, which is mainly equipped with an all-in-one machine and relatively cheap, but it is quite suitable for customers who like to play small games and surf the Internet.

　　The e-sports area is naturally the largest in the area, and it is full of computers configured for e-sports games, including Razer peripherals and HKC e-sports screens.

　　Recently, the rise of chicken-eating games has also made a lot of changes in Internet cafes. Bayou Internet Cafe has specially set up private rooms to bring friends to consumers to eat chicken in multiple rows.

　　There is a high platform in the e-sports area, which is a high-end configuration experience area. The configuration is GTX1080 and i7 6700K with full split water cooling blessing. There are six computers on one side and twelve computers on both sides, and there is a big screen live broadcast in the middle. It seems that the original intention of the design is to broadcast the LOL 5V5 game live, but now the consumption above is eating chicken, and the screen is also playing the anchor’s chicken-eating video.

　　The leisure and entertainment area on the other side is relatively small and fresh in decoration, with curtains on the seats to give consumers private space, which is very suitable for couples or friends to get together, chat, play games together and watch a small movie.

　　In addition, Bayou Internet Cafe also set up a mobile game area in a forward-looking way, which is also a test of Mr. Ouyang’s preference for consumer groups. After all, Internet cafes are positioned as a place for friends to meet, and now mobile games are hot, and everyone can get together to play mobile games. Can also achieve the purpose of the party.

　　Generally speaking, the atmosphere of Internet cafes makes people feel very comfortable. Dividing different sections can also adapt to the needs of various consumer groups, completely refreshing the cognition of Internet cafes in a winter. Next, we will continue the previous experiment to test the difference between the diskless system of Internet cafes and the computer performance of Internet cafes under our own system. In the third phase of our test of SO Hao Internet Cafe, we found that there is no difference in hard disk running scores between the two systems, but the diskless system will lead slightly in the number of game frames. Let’s see if it is the same in Bayou Internet Cafe.

　　Whole machine configuration:The computer host is in a small iron box under the game table, and there is no separate chassis, so the design is more integrated, and most people can’t find the existence of the host. In terms of computer hardware configuration, the core configuration is i5-6500+GTX 1060 3GB+16GB memory, which is a very balanced configuration. CPU, graphics card and memory will not be short boards, and they can basically play various 3A masterpieces smoothly. Next, let’s look at the differences between these hardware and our daily use one by one.

Memory:

　　In terms of memory, Bayou Internet Cafe uses Samsung DDR4 2100MHz general bar. We found this product in Taobao, and there are not many merchants selling it. It is estimated that it is mainly delivered by work packages, and its performance is quite satisfactory, but it is better than Samsung’s reputation of stable and reliable particles. Memory is more prone to problems in computer hardware, and internet cafes are taboo for computer instability, so it is reasonable to choose this memory stick.

Graphics card:

　　Bayou Internet Cafe uses GTX1060, which Internet Cafes prefer, but since Bayou Internet Cafe opened its doors for business the year before last, there was no GTX 1060 5G version at that time, so GTX 1060 3G version was adopted. From the picture, the specific model of the graphics card is Sotheby GTX 1060 3GB Destroyer. The performance of this graphics card can play most games smoothly, and the only shortcoming is the video memory. Many new games represented by eating chicken will occupy about 4GB of video memory even at 1080p resolution, but the video memory of this graphics card is just not enough, and playing some games will lead to the explosion of video memory.

Motherboard:

　　The motherboard uses ASUS EX-B150M-V3, and B150 motherboard and i5-6500 are considered as a cost-effective gold partner. As a first-line manufacturer, ASUS’s motherboard is also famous for its stability.

　　Next, we will be the same as before in Zhongshan.Test the performance of the original diskless system on the same machine and the performance after adding the Mingjue A6 Big Mac solid state (with win10 system) we brought. The graphics card drivers are NVIDIA 391.01.

　　CineBench R15 is a convincing CPU testing system. The Cinema 4D special effects software engine developed for the film and television industry is used to test a high-precision 3D scene rendered by CPU, which can support up to 256 logic cores. In addition, the new version also strengthens the investigation of shaders, anti-aliasing, shadows, lighting and reflection blur, and the detection of CPU performance is more accurate.

　　Summary:The test showed strange results. In our solid-state system, the CPU performance met the score of i5-6500, but it was obviously abnormal in the original diskless system, far from the normal level of i5-6500. Is it a software problem? Let’s keep testing.

　　CPU-Z is a well-known CPU detection software, and it is the most used software to detect CPU. Its own Benchmark can accurately judge the multi-core performance and single-core performance of CPU.

　　Test summary:In the CPU-Z test, the computer is still in an abnormal state under the diskless system. Is there something wrong with our CPU-Z software? I began to doubt life one winter.

　　X264 FHD Benchmark can effectively test the floating-point operation performance of CPU and the actual file-changing ability of multimedia audio and video.

　　Test summary:In the software for testing the actual ability of CPU, the performance of the computer under the diskless system is still poor, so it seems that it is not the software problem we brought.　　

　　Winrar is a commonly used compression/decompression software, and its own benchmark performance test can test the compression ability of a computer, which is similar to that of a computer.Processor performance and memory performanceIt matters.

　　Test summaryThe test results were still very embarrassing.

　　Fritz Chess Benchmark is a chess software, which can be used to test the computing performance of CPU.

　　Test summary:Chess is a software that simply measures the performance of CPU. It seems that the performance of i5 -6500 is obviously inhibited under this diskless system. Let’s see if other computer hardware will behave abnormally.

　　7-Zip is a completely free and open source compression software, and its own benchmark performance test can adhere to the decompression/compression ability of the computer, mainly measuringProcessor and memoryPerformance.

　　Test summary:The decompression performance is basically the same, but the compression performance of diskless system is still almost the same, but it basically belongs to the same performance.

　　AIDA64 is a tool for testing software and hardware system information, which can display every aspect of PC information in detail. AIDA64 not only provides many functions such as assisting overclocking, hardware debugging, stress testing and sensor monitoring, but also can comprehensively evaluate the performance of processor, system memory and disk drive..

　　Test summary:In terms of memory performance, this diskless system is much worse than the memory writing performance.

　　3Dmark is a software specially designed for measuring the performance of graphics cards by futuremark Company, and it has released 3Dmark99, 3Dmark2001, 3Dmark2003, 3Dmark2005, 3Dmark2006, 3Dmark vantage, 3Dmark 11 and The new 3DMark. Now, 3Dmark is not only a software to measure the performance of graphics cards, but has gradually turned into a software to measure the performance of the whole machine. 3DMark’s test physical score can be basically calculated.Actual game performance of CPU.

　　Test summary:From the test point of view, the graphics card performance of the platform is no problem, and the problem still appears on the CPU. This is the case under the running software, so how does it perform in the game?

　　Test summaryThe game "Survival of the Jedi" needs no introduction for a winter. I believe everyone is very familiar with it. In the test, we used the same DEMOS. Under the diskless system in the Internet cafe, the machine ran 46 frames, which was nearly 30 frames less than using our own system. Assuming that the performance under the diskless system is 100%, then the performance of the machine game has soared by 60% under SSD. How on earth is this fat?

　　What is behind this huge performance gap?Distortion of human nature or moral decayWhat’s the reason? After our conversation with Mr. Ouyang, we infer that there are several reasons. Let’s start with the startup principle and mechanism of the diskless system.

　　First, the network card of a diskless workstation is equipped with a Boot ROM. When the workstation is started by LAN, it will send a boot request signal to the server. When the server receives the signal, it will send boot data to the workstation according to different mechanisms. After the workstation downloads the boot data, the system control will be controlled by the Boot ROM.Go to some areas of memory.. That is to say, the diskless system will occupy part of the memory, SO whether it’s SO Hao Internet Cafe in Zhongshan or Bayou Internet Cafe in Guangzhou, they will give priority to ensuring that the memory is 16GB, and I believe other Internet cafes using diskless systems are also the same. And the memory is occupied, so it is understandable that the memory reading and writing performance will be affected to some extent.

Internet cafe system desktop

　　Second, when we communicated with Mr. Ouyang, we learned that the system of Internet cafes needs to meet the needs of consumers such as ordering food, calling service, charging and timing, so there are many programs hanging in the background, which leads to a certain degree of influence on the CPU performance of computers. However, the system of Soho Internet Cafe that we visited in the past did not have these humanized functions, which is related to the fact that the business direction of Soho Internet Cafe is more inclined to the positioning of traditional Internet Cafe, which mainly relies on network fees, while the positioning of Bayou Internet Cafe is more inclined to "coffee", and the user experience such as environment and good value-added services is more important, SO the system of Soho Internet Cafe is relatively streamlined, and it is even a little faster to run games in our previous tests.

　　The third reason is that the performance of disk reading and writing may encounter a bottleneck. The Internet cafe machine is divided into two parts: server and client. Under the diskless system, the client does not need to be equipped with a hard disk. All clients connect to the super-large hard disk in the server through the network and start it by using the system image in the hard disk. The files in the server hard disk can be read by all clients. If they are connected,Wire, network bandwidthIf it is not enough, it may cause data reading and writing to get stuck.

　　At present, most mature Internet cafes have a mature diskless system provider. When choosing a diskless system, Internet cafes will think and choose according to their business orientation. However, the difference in computer performance between customized systems is beyond our expectation. Therefore, PConline suggests that Internet cafe operators should check whether the diskless system has a great impact on hardware performance when choosing a diskless system provider. For example, the diskless system we evaluated this time has a great inhibition on computer performance, and it is a pity that the computer only played its original performance of 60%.
