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.

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.

　　Xinhua News Agency Beijing July 28 New Media Special Telegram: Focus on Taxi Reform Four Major Concerns of the People

　　Xinhua News Agency "Xinhua View" reporters Ding Jing, Qi Zhongxi, Zhao Wenjun

　　The "Guiding Opinions on Deepening Reform and Promoting the Healthy Development of the Taxi Industry" and the "Interim Measures for the Management of Online Booking Taxi Business Services" were issued recently, and the "boots" of taxi reform have been implemented. Can the reform ease the "difficulty of taking a taxi" and "expensive", and can private cars drive online taxis? Will the "share money" be reduced?

　　Can my car drive an online car-hailing? What are the conditions?

　　At present, many people driving online car-hailing are often investigated, and some people want to drive online car-hailing, but they are still waiting and seeing because of the unclear policy.

　　After the document was issued, worry and wait-and-see will become "past tense". The document gives online car-hailing platform companies legal status, supports the continuous innovation and standardized development of online car-hailing platform companies, and relaxes restrictions on online car-hailing platform companies to not require their own vehicles.

　　According to the regulations, the conversion of private cars to online car-hailing requires meeting three basic conditions: passenger cars with 7 seats or less; installation of vehicle satellite positioning devices and emergency alarm devices with driving record functions; and vehicle technical performance meeting the requirements of relevant standards for operational safety.

　　At the same time, the regulations also specify four requirements for online car-hailing drivers: obtaining the corresponding type of motor vehicle driver’s license and having more than 3 years of driving experience; no traffic accident crime, dangerous driving crime record, no drug use record, no drinking driving record, and no 12-point record in the last 3 consecutive scoring periods; no violent crime record; other conditions stipulated by the urban people’s government.

　　"It is worthy of affirmation that administrative reform should take the initiative to adapt to the trend of the’Internet + ‘era and the reality of the taxi industry, and face the problem head-on," said Yu Mingyuan, a highway transportation development research center at the Highway Science Research Institute of the Ministry of Transport.

　　Guo Jifu, director of the Beijing Transportation Development Research Center, believes that the new policy reflects respect for market laws. But for online ride-hailing included in the operation, its market behavior should be regulated.

　　It is worth noting that in order to encourage the "sharing economy", the new policy also allows private passenger car sharing, or "hitchhiking". However, the requirements are not for profit, and should be carried out during commuting hours or holidays. There should be a certain limit to the number of rides per car per day. Part of the travel cost is limited to direct expenses such as fuel costs and tolls.

　　Can "taxi difficulty" be alleviated?

　　Whether you can get a taxi during the morning rush hour, and whether you will be "rejected" when you go to the nearest hospital. "Difficulty in taking a taxi" is one of the most concerned issues for the people in the taxi reform. Experts believe that the change in the capacity scale is the key issue affecting the difficulty of taking a taxi for citizens.

　　As of the end of 2015, there were about 1.39 million taxis in China, about 8,500 taxi operating enterprises, and about 130,000 self-employed households. According to the document, the next step in the development of taxis is to adhere to the principle of giving priority to the development of public transportation, moderately developing taxis, coordinating the development of cruise cars and online cars, and promoting the gradual integration of the two formats.

　　Liu Xiaoming, deputy minister of transportation, pointed out that the "moderate development" of traditional taxis requires cities to take into account the actual situation of the city, reasonably grasp the scale of taxi capacity and the proportion of sharing in the urban comprehensive transportation system, and establish a dynamic monitoring and adjustment mechanism.

　　According to the requirements of the document, the number and scale of online car-hailing are controlled by various localities. Cheng Shidong, director of the Urban Transportation Office of the Comprehensive Transportation Research Institute of the National Development and Reform Commission, believes that the overall direction of the policy for online car-hailing is "deregulation". Previously, it was worried that the setting of the scrapping age of online car-hailing would affect the enthusiasm of some online car-hailing owners, but this condition in the document became "600,000 kilometers", and many private cars can be converted into online car-hailing, increasing part of the transportation capacity.

　　Guo Jifu believes that it is understandable that some cities with limited road resources and severe congestion may implement a number control on online car-hailing.

　　Will taxi prices go up or down?

　　According to the document, government pricing or government-guided pricing will be implemented for traditional taxi rates, and a dynamic adjustment mechanism for freight rates will be established. For online taxis, market-regulated pricing will still be implemented, except for those that the city people’s government deems necessary to implement government-guided pricing.

　　Zhou Hanhua, a researcher at the Institute of Law of the Chinese Academy of Social Sciences, believes that traditional taxis used to be set by the government, and the price adjustment had to go through a hearing. But this time using government pricing or government-guided pricing allows traditional taxi companies to adjust prices between the upper and lower limits according to market conditions, giving them more flexibility.

　　According to the document, online car-hailing practices market-adjusted prices, but it is worth noting that "unless it is necessary to implement government-guided prices". Guo Jifu believes that even for online car-hailing, consumers’ bargaining power is still very weak, so special weather such as rain and snow, peak hours, and congested locations require a certain price adjustment mechanism to protect the rights and interests of passengers.

　　At the same time, the document stipulates the low-price subsidy promotion behavior of online car-hailing platforms: online rental car operators shall not disrupt the normal market order by operating at a price below cost in order to crowd out competitors or monopolize the market.

　　"Some platform companies have seized the market through low-price subsidies and promotions, which has impacted the normal market order and affected the taxi industry and social stability," said the relevant person in charge of the Ministry of Transport.

　　Zhou Hanhua believes that subsidized promotions also need to be distinguished. It is not possible to operate below cost for a long time, but holiday "red envelopes" should be normal market competition activities.

　　"Generally speaking, the price of online car-hailing will not fluctuate too much." Cheng Shidong said that the current price of online car-hailing is basically market pricing, and the reduction of subsidies is also an inevitable result of market development. In the future, price competition will turn to service competition, and by improving service quality, it will create brand effect.

　　Will "molecular money" decrease?

　　"Molecular money" is the common name for the contract fee that taxi drivers hand over to the company, which is an important source of income for taxi companies. "I owe the company hundreds of yuan every day when I open my eyes" is a typical taxi driver complaining about high molecular money.

　　In the document, there are two main reforms related to molecular money: one is to implement term restrictions and free use of new taxi operating rights, and the operating entity cannot be changed; the other is that "molecular money" is determined and dynamically adjusted by taxi companies, industry associations, taxi drivers, and trade unions.

　　Cheng Shidong pointed out that "part money" includes the value of the concession right, and the cancellation of the paid user fee for the operation right is an important measure to reduce the "part money" of taxis.

　　"Negotiating on an equal footing and implementing dynamic adjustments will help taxi drivers have the voice over prices and raise their enthusiasm," Mr. Yu said.

　　At present, some regions have begun to explore reducing "part money". In Hangzhou, several companies return 10% of the contract fee to drivers, and through subsidies and rewards, "part money" has been reduced from 8,000 yuan per month to the current minimum of 6,400 yuan per month.

　　In Shanghai, Didi Chuxing, Shanghai Seagull Holdings and others have launched a "Shanghai Seagull Taxi Driver Service Agency". The service agency does not charge money, and drivers who join the club only need to pay a monthly service fee of 50 yuan to enjoy invoice management, vehicle commercial insurance, online tax payment and other services.

During the Spring Festival journey, have you completed these protective tasks?

Experts from the Provincial Center for Disease Control and Prevention remind: Wear a mask throughout the process, do a good job of personal health monitoring during the journey, and wash your hands, face, and clothes in time after returning home

The Spring Festival of 2021 is getting closer and closer to us. Although many people choose to celebrate the New Year on the spot, the personal flow is inevitable.

Under the current epidemic prevention and control situation, how to reduce the risk of travel? In the face of the possibility of relatively concentrated flow of people today and tomorrow, Liu Fuqiang, director of the Emergency Office of the Hunan Provincial Center for Disease Control and Prevention, reminded that passengers should wear masks throughout the process; minimize the number of meals on public transportation; do a good job of personal health monitoring on the journey; after returning home, wash your hands, face and clothes in time.

Before traveling, prepare masks, disinfection products and negative nucleic acid test certificates

Liu Fuqiang said that according to the "Notice on Doing a Good Job in Local Chinese New Year Service Guarantee Work" issued by the Central Office and the State Office, the people in high-risk epidemic areas should celebrate the New Year on the spot, minimize the personal flow, and prevent the spread of the epidemic due to the personal flow; People in medium-risk areas celebrate the New Year on the spot in principle, and those who need to travel under special circumstances need to be approved by the local epidemic prevention and control agency; low-risk areas advocate the masses to celebrate the New Year on the spot, and do not travel if necessary. Although many people choose to celebrate the New Year on the spot this year, there are still not a few homecoming wanderers who are eager to reunite with their families, and the personal flow is inevitable. If you travel, you should always take good personal protection, such as wearing a mask, washing your hands frequently, and using one-meter noodles.

Droplets produced when coughing, speaking, and sneezing are the transmission carriers of many viruses. Carriages, stations, service areas, and other places are crowded places, and wearing masks can effectively isolate droplets. It should be reminded that it is recommended to prepare a few more masks when you go out, so that you need to change the masks in case of emergencies or long journeys.

Contact transmission is the mode of transmission of the virus, and it is crucial to maintain hand hygiene. When taking public transportation, you must pay attention to hand hygiene. If there is no hand washing condition, you should prepare 75% alcohol hand sanitizer, disinfectant wipes and other products before traveling, so as to better sterilize and disinfect. In addition, you should carry some garbage bags to carry contaminants during the trip. For example, you can also use used masks to hold vomit when you vomit on the way.

There is also one of the most special and important "baggage" on the way back home this year, which is the negative certificate of COVID-19 virus nucleic acid test. The negative certificate of COVID-19 virus nucleic acid test can be a paper report, or you can find your own nucleic acid test results on the national government service platform. " Winter and spring rural areas COVID-19 epidemic prevention and control work plan is clear: inter-provincial returnees, returnees from cities where medium and high-risk areas are located in the province (internal personnel in medium and high-risk areas are not mobile in principle), imported cold chain food practitioners in the province, port direct contact with imported goods practitioners, isolation staff, transportation personnel and other key groups, need to hold a valid COVID-19 virus nucleic acid test within 7 days to return home negative certificate. Holding a negative nucleic acid test certificate does not need to be isolated after returning home, but needs to carry out 14-day home health monitoring, during this period do not gather, do not flow, carry out a nucleic acid test every 7 days. All townships (streets) and administrative villages (neighborhood committees) implement a responsibility system, implement grid management for returning personnel, and do a good job in registering, health monitoring, and handling abnormal conditions.

Take a train or plane, etc., wear a mask throughout the process, and do a good job of personal health monitoring

Trains, planes, buses, etc. are the means of transportation that many people take when returning to their hometowns. These public transportation vehicles are densely populated and relatively closed in space. Problems such as passengers walking around casually and wearing irregular masks bring many hidden dangers to epidemic prevention and control. For example, passengers wearing masks are not standardized, and even take them off or put them in their jaws. Or passengers take off masks to eat and drink. Due to the small seating gap, taking off masks to eat and drink will also increase the risk of virus transmission. For example, in the queuing, ticket checking, etc., individual passengers cannot maintain a one-meter distance; some passengers move around in the train compartment, or even cross the compartment; if the journey time is long, some passengers will gather at the train gate to smoke on the platform before boarding or when the train stops, these factors may increase the risk of virus transmission.

Liu Fuqiang suggested that when taking relatively closed public transportation such as planes, trains, and buses, try to choose online real-name ticket purchases and implement contactless payment; abide by order, queue in an orderly manner, maintain a safe social distance of more than one meter, and avoid waiting in groups; actively cooperate with staff to measure body temperature and take the initiative to declare health status. If there is an abnormal body temperature, you must follow the staff’s arrangement and emergency response; take appropriate seats, sit in separate or scattered places as much as possible to reduce the number of walks; wear a mask throughout the process; disinfect your hands and avoid touching your mouth, nose, eyes, etc. with unclean hands; cover your mouth and nose with elbow clothes when sneezing or coughing; in order to reduce the risk of exposure to yourself and others, try to avoid close contact with others. If you need to chat at close range, be sure to wear a mask; reduce the risk of exposure in public The number of meals on the means of transportation, encourage alternate meals with others; properly keep air tickets, train tickets, bus tickets and other bills to cooperate with the investigation of possible close contacts or epidemic traceability investigation; pay attention to the health status of surrounding passengers, avoid close contact with people with suspicious symptoms such as fever and cough, and do a good job of personal health monitoring during the journey. Once the body temperature is abnormal or suspicious symptoms appear, cooperate with temporary isolation, health investigation, etc.

Take a private car or an online car, etc., ventilate more, and do not stay in the service area for a long time

Many citizens, especially those whose hometown is in the province, will take online car-hailing, taxi or drive a private car home for the Chinese New Year.

Liu Fuqiang said that when choosing online car-hailing, taxis and other means of transportation, passengers should sit in the back row, wear masks throughout the process, do a good job of health registration, and cooperate with body temperature measurement; try not to carpool with others; pay attention to hand cleaning on the way, do not take off the mask when coughing and sneezing, and avoid touching the mouth, nose, eyes, etc. with dirty hands; when conditions permit, open more windows for ventilation. Online car-hailing and taxi drivers should also pay attention to opening windows for ventilation if there are no passengers in the car; regularly disinfect high-frequency contact items, such as door handles, car armrests, seats, seat belts and their sockets.

If citizens drive their private cars back to their hometowns, they should check the condition of the car in advance and fill it up with oil; regularly clean the door handles, armrests in the car, car keys and steering wheels, commonly used buttons, seats, seat belts and their sockets; ventilate the car well; do not turn on the vehicle air conditioner for domestic circulation; do not drive tired, you can rest and adjust properly in the service area, but do not stay in the crowded service area for too long; prepare sufficient food, drinking water, etc. in advance to reduce the number of shopping and meals in the service area; if you need to go to the toilet, shopping, etc., get out of the car and enter the service area and other public places to wear masks, and wash your hands in time, or disinfect your hands with hand sanitizer, disinfectant wipes, etc.

Liu Fuqiang reminded that before arriving at the destination and entering the house, it is best to clean your hands with running water or hand sanitizer, disinfectant wipes, etc.; after entering the house, wash your hands and face in time, preferably take a bath, change clothes in time and wash or disinfect. Once symptoms such as fever and cough appear, don’t panic or hide, and report your health truthfully to the village committee (especially rural returnees) or the neighborhood committee where you are located; go to the fever clinic (fever clinic) of a regular hospital in time. Do not take antipyretics, cough medicine, etc. Wear a mask throughout the visit to reduce personal contact.
