在这场 AI 硬件的寒武纪大爆发中,苹果看似反应迟钝,也确实在大模型、AI 落地上表现不太让人满意,可如果这套阳谋最终跑通,Eddy Cue 当年的那句豪言,或许真的需要微调几个字,才能跟上苹果的野心:

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.
