Core Viewpoint - The article discusses vivo's development of the Blue River operating system, emphasizing its transition from self-research to open-source, driven by the need for a secure, lightweight, and versatile OS in the AI era [1][20]. Group 1: Operating System Evolution - The operating system has become a critical component in the AI era, acting as a gatekeeper for hardware resources and data flow, while also raising security concerns due to increased vulnerabilities [3][4]. - Traditional operating systems, primarily built on C language, face structural limitations in adapting to modern demands for lightweight and secure systems [4][12]. Group 2: Rust Language Adoption - Rust is identified as a solution to overcome the limitations of traditional programming languages, offering memory and concurrency safety without sacrificing performance [5][9]. - The Blue River kernel, built using Rust, aims to provide a secure runtime environment, with a minimal memory footprint of just 13KB, making it suitable for various devices [12][14]. Group 3: Open Source Strategy - vivo's decision to open-source the Blue River kernel is aimed at fostering an ecosystem around Rust, encouraging developer engagement and collaboration [21][22]. - The company is actively promoting Rust through competitions and partnerships with academic institutions, positioning itself as a leader in the Rust programming community [22][24]. Group 4: Future Outlook - The launch of the Blue River operating system marks a significant step for vivo in addressing user experience challenges and adapting to the evolving landscape of smart devices [18][19]. - The open-source initiative is seen as a starting point for building a robust ecosystem around the Blue River operating system, contributing to the growth of domestic Rust language applications [26].
