Vivo helps digital transformation, Blue River operating system promotes new development of open-source technology

The Open Atom Developer Conference 2023, an annual developer event led by the Open Atom Open Source Foundation (hereinafter referred to as the Foundation), was held in Wuxi, Jiangsu on December 16-17. Vivo, as a partner of this conference, was invited to participate in the opening ceremony. At the same time, as a core member of the Open Atom Developer Conference, vivo actively promotes the establishment of a fast application ecosystem branch to build an operating system software ecosystem with the industry and help the software ecosystem prosper.

Yang Chun, general manager of vivo’s software system integration department and general manager of Blue River operating system, gave an opening speech on the theme of "General artificial intelligence leads the new era of operating system" at the meeting, and expressed core views on the development prospects of AI and the technical concept of Blue Heart Big Model and Blue River System. "With the vigorous development of AI, AI will inevitably combine with various forms of end point devices to form a new intelligent experience. The combination of artificial intelligence and end point devices will form a new intelligent experience, and the future operating system will also be more diversified. At the same time, it will usher in a comprehensive change in interaction patterns, application ecology, technical architecture, etc. Based on the above thinking, we insist on independent research and development of operating systems, and actively participate in the tide of ecological construction. "

AI and end point devices combine to bring a more intelligent and diverse operating system experience

On November 1, 2023, vivo released the self-developed Blue Heart Big Model Matrix, which contains three parameter orders of one billion, ten billion, and one hundred billion. A total of 5 self-developed big models have the characteristics of large and complete, strong algorithm, true security, self-evolution, and wide open source. It fully covers core scenarios and leads the industry in model capabilities. Vivo also took the lead in open sourcing the 7 billion parameter level Blue Heart Big Model 7B and the corresponding fine-tuning framework. Developers can fine-tune based on the Blue Heart Big Model 7B, develop models and applications suitable for their own business, and try to commercialize. Based on the above thinking, vivo released the Blue River Operating System, a self-developed smart operating system that has been built for many years. It has three characteristics: inherently smarter, inherently smoother, and inherently safer.

Smart, smooth, and secure, Blue River defines the future of the operating system

As a self-developed smart operating system in the era of general artificial intelligence, Blue River Operating System expands the ability of multi-modal input and output methods based on the AI large model at the intelligent level, and supports multiple recognition paths such as voice, picture, and text. At the same time, Blue River Operating System supports a new paradigm of application development. It can realize AI service engines and multi-mode input subsystems, and has many new applications of smart operating systems. It can provide code generation and graphic generation capabilities as well as customization of system vision such as themes and wallpapers. It is an essential tool for emerging productivity and creativity.

Figure: The three characteristics of the Blue River operating system are inherently smarter, inherently smoother, and inherently more secure

In order to further improve the fluency of the system, vivo must ensure that the Blue River system can run on very low-configuration devices on the one hand, and on the other hand, starting from full-stack technology, it has made breakthroughs in the five key technical directions of operating system programming language, runtime, super coroutine mechanism, virtual graphics card framework, and memory management algorithm. It has realized a series of key technologies, and the operating efficiency has been significantly improved, making the system smoother and easier to use.

Industry data shows that about 70% of serious security bugs in operating systems are related to improper memory use, and it is difficult to completely solve the problem of fixing security bugs. In this regard, vivo chose Rust language as the development language of the system framework, becoming the first operating system written in this language in the industry. The advantage of Rust language is that it can detect security problems caused by improper memory use during the compilation stage, ensuring memory safety and concurrency safety from the source.

In addition, Blue River Operating System uses BlueXlink connection technology based on the distributed design concept, which is widely compatible with industry standard protocols and serves smart home, smart travel, smart office and other scenarios, supporting Blue River Operating System’s IoT intelligent experience.

Digital transformation promotes the rise of open source, technological innovation drives the future of the industry

Cultivating open source ecology is a key task of the national software development strategy. The national 14th Five-Year Plan includes open source as a long-term goal for the first time. Under the general trend of digital transformation, basic software and hardware have become an important link related to national security. Today, China has become the world’s largest open source app store. vivo, as a core member unit, promoted the establishment of the China Software Association Fast Application Ecology Branch to jointly build fast application technology standards. In 2021, the source code implementation of fast application technology standards was officially donated to the Open Atomic Open Source Foundation and became an incubation project hapjs. In 2023, the number of devices in the industry supporting the fast application technology standard of hapjs has exceeded 1.50 billion. The self-developed Blue River operating system released by vivo this year is also compatible with this ecological standard, and will jointly build an operating system software ecosystem with the industry.

In the future, vivo will continue to deepen its efforts in the field of scientific and technological innovation, cooperate with ecological partners, and make every effort to promote industrial ecological construction, contributing to the prosperity and development of the industry.

The ＂groupies＂ in Sea Science City – ＂Yuanwang＂ measures the group portraits of scientific workers on board

　　On the morning of January 20, Yuanwang 6, which successfully completed the 26th and 27th Beidou navigation satellite maritime monitoring and control missions, docked at the wharf of the China Satellite Maritime Monitoring and Control Department, which also means that the China Satellite Maritime Monitoring and Control Department has started a new year of work.

　　The "Yuanwang" survey ship is known as the "Maritime Science City". In 2017, the "Yuanwang" fleet successfully completed 11 maritime measurement and control missions. Here, the Science and Technology Daily reporter saw that the "star chasers" in the Maritime Science City chased their dreams in the ocean and built their dreams in space, and used practical actions to write a chapter for the realization of the "space dream".

　　Gold Operator Hu Jinhui: Ocean Holding Star "First Person"

　　A basin of clear water, a ping-pong ball, a pair of chopsticks – a game was going on fiercely. The swell lashed violently against the side of the boat, the hull swayed, and the ping-pong balls in the water flipped non-stop. In the flash of lightning, a pair of chopsticks firmly clamped the ping-pong ball.

　　"It’s Hu Jinhui again!" The onlookers cheered. Hu Jinhui – Yuanwang No. 6 ship measurement and control technician, the main operator of a certain type of measurement and control radar.

　　To measure and control space targets at sea, the operator is first required to track the target quickly, accurately and stably. The task of the radar operator is to use the radar to track and capture the target at the first time, which is directly related to the success or failure of the maritime measurement and control mission. They were the first to see the satellites in the sky on the ocean, so they were called the "first people" in the ocean to lead the star.

　　"Playing this small game is not only for entertainment, but also to exercise the radar operator’s eyesight, wrist strength and arm strength." Speaking of professionalism, Hu Jinhui gushed, "The electromagnetic wave interference on board, sea level refraction interference, etc. will all affect the capture target. How to eliminate interference and quickly capture the target requires the operator to have keen observation. The left hand controls the’orientation ‘and the right hand controls the’pitch’. The combination of the two is equivalent to drawing circles with one hand and drawing squares with the other. In order to accurately control the equipment, the operator’s hands need to be extremely skilled and closely coordinated…"

　　During a mission, the target appeared more than ten seconds in advance, the sky was still raining, and the target kept flashing and jumping, making it difficult to capture. Hu Jinhui was stunned, his head was blank, his palms were sweaty, and his calves were trembling. After the initial tension passed, he forced himself to calm down, find the predetermined track, and quickly captured the target with the stunt he had practiced for many years.

　　In 2011, Shenzhou VIII and Tiangong-1 were rendezvous and docking in space for the first time. Yuanwang VI needed to track the spacecraft 100 laps. 100 laps, laps are all tests. The sea conditions are poor and the tracking time is long, and both physical and psychological are subject to multiple tests. In this protracted battle, Hu Jinhui and his team successfully completed the mission. In 2013, when performing the mission, in the face of unprecedented severe sea conditions, he and his colleagues carefully tested and maintained the equipment, and finally achieved "zero failure" of the radar antenna. The tracking accuracy of the circle meets the requirements of the index…

　　Since boarding Yuanwang, Hu Jinhui has successfully completed more than 50 missions. Hu Jinhui said: "My dream is to keep working in my post and do my best to contribute to the aerospace industry."

　　The new crew of Dr. Tian UK: giving the professional group the wings of efficiency

　　Rich theory and lack of practice, plump ideals and cruel reality, the two encounter, so that the new crew of the Yuanwang No. 6 ship, Tian Yingguo, was severely slapped in the face as soon as he got on the ship.

　　The first time he went to sea, he went to the harsh Indian Ocean, and the seasickness that was already commonplace to others made him complain.

　　The first time he was on duty, unfamiliar equipment, numerous circuit diagrams, and complex signal flow charts kept him in a hurry.

　　The first time he was on a mission, sitting behind the monitoring desk, the tense atmosphere and rigorous process made him, who was responsible for a tiny part of the satellite launch mission, feel his own insignificance and the glory of his mission.

　　Difficulties always have to be overcome. Learn from the basic principles, start from the basic operation, actively communicate with the post master if you don’t understand, and work overtime to make up lessons if you don’t understand. After the foundation was firmly established, Tian Yingying made rapid progress. In just two months, he had become proficient in a series of operations such as theodolite star measurement and deformation point detection, and understood the principles, becoming a qualified optical post technician.

　　After successfully passing the apprenticeship period, he did not stop his research. Taking charge of equipment is a basic requirement for every position, and Tian Yingying set himself a higher goal – to find out the equipment is insufficient and correct it.

　　When performing offline data comparison on two different types of inertial navigation equipment at one time, he found that this manual comparison mode was time-consuming and labor-intensive, and the operation steps were cumbersome. The accuracy and timeliness were also highly susceptible to human factors.

　　Why not give full play to his strengths and use automated software instead of manual scientific comparison? For Tian Yingying, who has been working on software data processing in the laboratory for a long time, everything seems to be a natural fit. After consulting data, discussing and analyzing, optimizing algorithms, and integrating interfaces, in repeated attempts and explorations, he successfully developed the "offline comparison software for a certain type of inertial navigation data of the surveying ship". This software was successfully run for the first time, reducing the comparison time from more than 10 minutes to 4 minutes, and the comparison accuracy was greatly improved.

　　In just 100 days after boarding the ship, the new crew member Tian UK developed nearly 10 small software, including theodolite star measurement optimization software and ship elevation calculation software, which gave the professional team the wings of efficiency and made maritime measurement and control more accurate.

　　System Engineer Lei Guojian: The land-sea relay looks at the "China Star" from a distance

　　Lei Guojian, who had been longing for the sea since he was a child, came to work on the "Yuanwang" after graduating from college in 2008. Unexpectedly, he was assigned to the Yuanwang No. 2 ship, which was about to retire from the maritime measurement and control line. "Although Yuanwang No. 2 ship has outstanding merits, the suspension of sailing means that it cannot go to sea!" Lei Guojian was a little depressed.

　　It doesn’t matter if the ship doesn’t go to sea, people are the most terrifying if they don’t have the will to fight. Lei Guojian, who cheered up, took the satellite long tube task as a maritime measurement and control task and explored a new model of "manned, unattended". The staff was reduced from 6 to 2, and the long tube task of 16 satellites and more than 1,150 laps was successfully completed, which drew a successful conclusion to the measurement and control process of Yuanwang No. 2.

　　In October 2014, Yuanwang No. 7 ship officially started construction, and Lei Guojian was selected as the first batch of key personnel to go to the equipment development plant to start equipment and production learning and quality supervision.

　　He fought for more than 600 days and nights in a row and traveled to more than 10 cities. He participated in the review of more than 250 equipment design drawings, found more than 20 errors in the drawings, solved more than 50 equipment problems, and firmly held the key to equipment quality control. He made great contributions to the smooth completion of Yuanwang No. 7 ship’s measurement and control equipment and the rapid formation of measurement and control capabilities.

　　In May 2016, there was a problem in the first comprehensive exercise of the whole system and full staff after the construction of Yuanwang No. 7 ship – the signal flashed out! However, from the transmitter to the receiver, from the cable to the plug, from the hardware to the software one by one, the crux was not found. Lei Guojian, who was familiar with the No. 7 ship, led the professional team to work overtime to investigate one by one. The problem was finally identified as an error in the transmission polarization method, which completely solved the major technical problems.

　　In the Shenzhou 11 manned flight mission, Yuanwang No. 7 was the first stick in the measurement and control of the land-sea relay. In an emergency when the target was about to enter the station, an equipment fuse blew and an alarm was issued. Lei Guojian made an emergency investigation and successfully located the faulty part, so that the equipment resumed normal work. Under the leadership of Lei Guojian, the professional team worked continuously for 20 hours, providing strong measurement and control support for the accurate orbit operation of the Shenzhou spacecraft. The professional group he led was rated as a "high-quality team" due to its excellent business ability and successful completion of the task. (Reporter

Wild boar is no longer a national protected wild animal. How to find the balance between protection and hunting？

　　Xinhua News Agency, Chengdu, July 7th Question: Wild boar is no longer a national protected wild animal. How to find the balance between protection and hunting?

　　Xinhua News Agency "Xinhua Viewpoint" reporters Zhang Chaoqun, Gao Jianjun and Sun Qingqing

　　A few days ago, National Forestry and Grassland Administration released the newly adjusted List of Terrestrial Wild Animals with Important Ecological, Scientific and Social Values, and the wild boar that caused serious damage in many places in the country was transferred out of the list, which means that it no longer belongs to the wild animals protected by the state. What is the realistic background of this change? Does it mean that you can kill at will after calling out the list? How to find the balance between protection and hunting? "Xinhua Viewpoint" reporter conducted an investigation and interview on this.

　　Wild boar flooding in many places frequently hurts people and destroys things, and it has been called for a long time to delete them from the list.

　　The newly adjusted "Three Owns" list includes 1924 species of wild animals. Compared with the catalogue first published in 2000, more than 700 species of wild animals have been added while basically retaining the original species. The species listed in the original list are not naturally distributed in China, or widely distributed, with a very high population, no extinction risk, and may even cause harm.

　　"There is no threat to the survival of wild boar, and the population in many areas is too high, which is in line with the basic principle of adjustment." Jin Kun, a researcher at the Institute of Forest Ecological Environment and Nature Protection of China Academy of Forestry, said.

　　In 2021, Tudeng Xiangba, the 45-year-old village party secretary and village committee director of Zengde Village, Shangmula Township, Litang County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, was killed by a wild boar attack on his way to the mountain.

　　In Yuanshanzi Village, Tongjiang County, Bazhong City, Sichuan Province, wild boars "patronize" every three to five nights. Among the 334 households in the village, more than 100 villagers planted crops and fruits, which were damaged by wild boars. According to the comprehensive villagers’ evaluation of Tongjiang County Wildlife Conservation Center, there are more than 20,000 wild boars in the county. From March 2022 to March 2023, Tongjiang County accepted more than 700 reports of wild animals such as wild boar.

　　Since 2022, there have been more than 1,300 incidents of wild boar accidents recorded in Mianyang City, Sichuan Province, and eight people have been injured and more than 3,500 mu of crops have been damaged.

　　To this end, many county governments have to buy commercial insurance to make up for the losses caused by wild boar to farmers. Tongjiang County has spent more than 400,000 yuan in recent years to buy government rescue insurance for wildlife damage. In Mianyang City, five counties with serious wild boar hazards spend 100,000-300,000 yuan each year to buy commercial insurance with insurance coverage ranging from 1.2 million to 2 million yuan.

　　Not only in the countryside, but also in Nanjing, Hangzhou and other places. The data show that wild boar is distributed in 28 of the 31 provinces in China, among which 857 counties (cities, districts) in 26 provinces are harmed by wild boar, which has adversely affected the production and life of local people.

　　During the interview, the relevant departments of forestry and grassland in many places revealed that from the perspective of being conducive to social development and people’s lives, it has been called for a long time to delete wild boar from the "three haves" list. To this end, many places have made detailed wild boar population surveys and hazard assessments.

　　Can I kill wild boar at will in the future?

　　"I really can’t help it. The wild boar will eat 70 acres of my more than 100 acres." In a case heard by the People’s Court of Xichuan County, Henan Province in 2021, Wu Mou, who captured more than 8 wild boars with prohibited hunting equipment in the game reserve and during the game ban, stated this to the court.

　　Now, does bringing wild boar out of the list mean that you can kill wild boar at will?

　　Jin Kun and other experts said that after the wild boar was brought out of the list, it was easier to carry out hunting activities, but the principle of giving priority to protection should still be adhered to, and the provisions of laws and regulations such as no hunting area, no hunting period, no hunting tools and hunting methods, and national gun management should be strictly observed. When hunting wild boar, no harm should be caused to other wild animals protected by the state.

　　According to the relevant person in charge of the Wildlife and Wetland Protection Department of Sichuan Forestry and Grassland Bureau, one of the advantages of transferring wild boar out of the list is that the procedures are simpler at the grassroots level when dealing with the harm caused by wild boar and adopting population control.

　　"One pig, two bears, three tigers and leopards." During the interview, villagers in many places used this folk saying to describe the strong aggression of wild boar.

　　"The villagers can’t clean up the wild boar without tools", "the biting force is too strong", "the teeth are like knives" and "they dare not do it". The villagers in Xinyi Village, Muzuo Township, Pingwu County, Sichuan Province commented on the "lethality" of wild boar. Du Lin, the village party secretary, said, "A few years ago, an old lady in the village met a wild boar on the mountain, and her ankle was bitten off by a wild boar. She was barely able to walk on crutches after living in the hospital for more than two months."

　　Li Zhongyi, the criminal investigation team leader of the Forest Police Detachment of Mianyang City Public Security Bureau, said that most wild boars are social animals, and generally two or three sows hang out with a group of young pigs. In order to protect their young, adult sows are usually irritable and aggressive. Wild boar has territorial consciousness and may attack other creatures in the territory.

　　The reporter learned that there are only three hunting teams in Mianyang, a city with a good ecological environment and frequent wild boars, all of which are non-governmental organizations. Among them, only one team was allowed to use guns by the public security organs for the record.

　　How to find the balance between protection and hunting?

　　Experts interviewed said that the frequent appearance of wild animals such as wild boar not only caused crop losses, but also reflected the trend that the ecological environment in many places in China continued to improve and the habitat of wild animals expanded. "The ecology is getting better and better these years." Yang Tingxiu, a 50-year-old villager in Luoyigou Village, Qingxi Town, Qingchuan County, Sichuan Province, said that wild boar, deer and monkeys went to the fields to eat crops, which was the trouble after the ecological improvement.

　　Experts suggest that wild boar is harmful, but it is not a "pest". Studies have shown that the habit of wild boar turning over the soil and arching the ground can effectively promote the healthy succession of forests. At the same time, the seeds of many plants in nature are also spread through the eating and activities of wild boar.

　　The insiders believe that it is necessary to adhere to the principle of protection priority, find the balance between hunting and protection, and make scientific policies to achieve harmonious coexistence between man and nature. Otherwise, it is inevitable to fall into "indiscriminate killing — The number has dropped sharply — Protection — Overflow — The pattern of indiscriminate killing.

　　Some grassroots cadres and the masses have called for the local government to formulate special control methods in areas where wild boar causes frequent harm. For example, the public security organs can properly participate in wild boar hunting activities, or approve private professional hunting teams to be equipped with a certain number of special firearms. At the same time, strictly regulate and implement the harmless treatment process and comprehensive utilization regulations such as sterilization, deep burial or incineration of prey carcasses, and strictly prohibit wild animals from flowing to the table.

　　Experts warned that if Lu Yu wild boar, should keep calm, quickly find the surrounding terrain and shelter conducive to hiding. If the wild boar takes the initiative to attack, it should dodge to both sides to avoid the frontal collision of the wild boar; When you are deadlocked, try to find a tall and easy-to-climb tree to climb two or three meters, and call the police for help on the premise of your own safety.
