Associated Press reporter Anthony Izaguirre in Albany, New York, contributed to this report.
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.

创作的压抑，让塔可夫斯基最终选择远赴意大利，接受西方制片人的邀约拍摄《乡愁》。他将对民族性的无穷追问糅进了《乡愁》的镜头里。剧情从来都不是这部影片的核心，漂泊、回忆、孤独，还有对故土深入骨髓的怀念，共同交织成如雾霭般难以散去的哀愁。在日记中，他记录着在意大利的创作心境，也写下了对这部作品的期许，而影片中那个戈尔恰科夫手持蜡烛缓缓走过水池的漫长镜头，不仅成为电影艺术史上不可复制的经典，更成为塔可夫斯基的“自我画像”，照见了一个异乡人的精神漂泊。
