3月2日消息，中欧航线票价暴涨。以上海-巴黎为例，3月4日直飞航线的经济舱机票已售罄，3月5日的直飞航线经济舱机票已涨到30248元，平时5000元左右。本周上海-巴黎直飞航线最便宜的经济舱票价都在16000元以上。随着中东两家国际航司暂停所有航线运营，以及国内航司取消中东航班，此前大量通过阿联酋航空和卡塔尔航空中转飞欧洲的旅客，选择直飞航线飞行，带来中欧航线需求大增。
Abstract:Package managers are legion. Every programming language and operating system has its own solution, each with subtly different semantics for dependency resolution. This fragmentation prevents multilingual projects from expressing precise dependencies across language ecosystems; it leaves external system and hardware dependencies implicit and unversioned; it obscures security vulnerabilities that lie in the full dependency graph. We present the \textit{Package Calculus}, a formalism for dependency resolution that unifies the core semantics of diverse package managers. Through a series of formal reductions, we show how this core is expressive enough to model the diversity that real-world package managers employ in their dependency expression languages. By using the Package Calculus as the intermediate representation of dependencies, we enable translation between distinct package managers and resolution across ecosystems.

小鹏在技术方面的动态也很多：比如，自动驾驶中心与智能座舱中心合并为“通用智能中心”，打通底层AI研发，让智驾、座舱、机器人共用同一套技术中辆；计划在一季度推送第二代VLA，何小鹏将仅训练这一个模型，就投入了3万卡算力和超过20亿元研发费用。但上述渠道人士提到，在20万级的市场里，大量消费者对“智驾溢价”还存在观望。
