Tianwen 1 successfully fire: using the domestic research Kirin operating system
Not long ago, the Tianwen 1 lander successfully landed on Mars, using China’s independently developed Kirin operating system. During the “Chang ‘e-3” mission, the Kirin team had encountered unprecedented extreme challenges due to the strict requirements for the stability and real-time performance of the operating system. Over the course of the mission, more than 180 problems were documented. Among these problems, the most frustrating is that the Qylin team: the space sector proposed that the real-time response accuracy of the operating system is 8 milliseconds, while the general system can achieve a real-time accuracy of 20 to 30 milliseconds at most. More than 180 problems were finally solved before Chang ‘e-3 was launched.
China has more than 900 million Internet video users, including 160 million Internet users under the age of 20
The number of Internet video users in China will exceed 900 million for the first time in 2020, ushering in an era of dividends for the online video industry, according to a report on China’s Internet Audiovisual Development 2021 released by the China Network Audiovisual Program Service Association earlier this month. There are 873 million short video users, who consume more than 2 hours per day on average. Users have a stronger demand for high-quality content in the medium and short video market. In the past five years, the number of online audio-visual users in China has increased steadily. China has 260 million “silver” Internet users and 160 million Internet users under the age of 20. All these are new growth points for the development of the online audio-visual industry.
Huawei, OPPO, VIVO and Xiaomi took the lead in formulating the fast charging agreement to unify the technology
Recently, the Telecom Terminal Industry Association issued the Converged Fast Charging Standard “Technical Specification for Converged Fast Charging of Mobile Terminals”. To solve the industry spot, green energy working group (WG10) work actively, China mail tunnels, huawei, OPPO, vivo, millet by technical specification for the mobile terminal fusion quick charge, get the glory, silicon lijie, red core micro cool, LiHui science and technology, the treasure to electronic, electrical network, terminal, chip companies and industry partners support. In the process of standard development, Huawei, OPPO, VIVO, Xiaomi and other head manufacturers broke the inherent technological thinking pattern and took the lead in developing a unified technical standard for fast charging of mobile terminals for the purpose of quick charging compatibility, so as to adapt to the long-term development needs of industrial ecology.

Chinese Academy of Sciences releases domestic open source RISC-V processor Xiangshan
At the first RISC-V China Summit, the Chinese Academy of Sciences released the domestic open source high-performance RISC-V processor core — Xiangshan. Experts from the Chinese Academy of Sciences said that at present, the CPU field does not have an open source mainline like Linux, so the R&D team decided that the industry needs an open source high-performance RISC-V core, which can be widely used by the industry, but also support the academic community to experiment with innovative ideas, with the goal of surviving for at least 30 years like Linux. Xiangshan is under the support of the Institute of Computing Technology of the Chinese Academy of Sciences and Pengcheng Laboratory, through the China Open Directive Ecological (RISC-V) Alliance, the industry enterprises together to develop an open source high-performance RISC-V processor core, the first mass-production version “Yanqi Lake” is scheduled to be released in July this year, using TSMC 28nm process.

Netease youdao Open Source EMLL: High Performance End-Side Machine Learning Computing Library
Netease youdao AI team has independently designed and developed a high-performance end-to-side machine learning computing Library — EMLL(Edge ML Library), which has been opened source recently.
EMLL is designed to accelerate end-to-side AI reasoning. It provides high-performance machine learning computing libraries based on end-to-side processors, supporting data types such as FP32, FP16, INT8, etc. It has been applied in NMT, ASR, OCR engines of intelligent hardware products such as netease youdao dictionary pen, Translator King and Super Dictionary, greatly improving computing performance. Improve the user experience.
Google enriches JetPack and introduces AppSearch search library
Google recently added a new feature to JetPack called AppSearch, which is now in Alpha. Officially described as a search library for managing locally stored structured data, AppSearch includes APIs for indexing the data and retrieving the data through full-text searches. You can use this library to build custom in-app search capabilities for users. When I look at in-app search, the first thing that comes to mind is the search page in the Android Settings. For example, search displays two words, which will display all the entry features that contain the word “display”.
Baidu front-end picture synthesis tool library MI open source
Mix-img is a front-end photo synthesis tool library, which can combine multiple images and text into a brand new image. As a lightweight image compositing solution, MI supports multiple image compositing in parallel, reducing image compositing time, improving the development efficiency of front-end developers and improving the development experience.
The core value of MI is the ability to quickly combine multiple images or text into a single image to display to the user or to share a flashy scene with simple configuration input.

Aurora Unified Messaging (UMS) new version online! Multidimensional data statistical analysis to boost the growth of operations
Operation is the bridge connecting users and products. For all operators, there is a common ultimate goal: to improve transformation, reduce costs, and maximize the push effect. However, an excellent push operation is not a simple “stacked” push of multiple message channels. Instead, it integrates each push independently into a whole through the integration of channels, users and content, so as to generate synergies, reduce internal friction and save operating costs, and finally achieve the operation effect of 1+1 >.2. Because of this, unified message push is more and more favored by enterprises.
Aurora, a leading developer service provider in China, has released UMS 2.0. The new version of UMS 2.0 adds support for third-party channels, message delivery methods, message delivery policies and security audit mechanisms to the existing intelligent management of multiple message channels. The most important thing is to add more dimensions of statistical analysis to help operators understand the laws and values behind the data, thus boosting the improvement of operation effect.
Pay attention to the official public number of the Aurora, the Internet every week to catch all!
