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.

日本推进“再军事化”有实际路线和行动，一个新型的军工复合体正在加速形成。近年来，日本扩军备武步伐加速，防卫费从2012财年到2026财年连续14年上涨，2022年以来更是实现3年内翻番。“国家级操盘”让日本军工企业赚得盆满钵满，甚至在资本市场上制造了“军工泡沫”。数据显示，自2022年11月以来，三菱重工股价涨幅超过650%，IHI株式会社股价涨幅超过480%，川崎重工股价涨幅超过280%。与此形成鲜明对照的是，同期日本制造业平均年增长率还不到1%。，推荐阅读heLLoword翻译官方下载获取更多信息
