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.

比錢更難挽回的，是家庭關係的撕裂。劉先生夫妻倆與丈母娘溝通保健品問題時，矛盾迅速升級，丈母娘一度不再與他們聯繫。在老人們看來，直播間裏那個每天陪她聊天、教她養生的主播，比一年回家一次的子女更像「家人」。這種信任的倒置，正在成為無數家庭中沉默的裂痕。
