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.
再直白点，就是你买回去要么自己跟维京重新谈，要么自己重做一套系统——成本？时间？自己掂量。

印奇最近也表示，AI硬件不是先画外观，而是先想清楚“什么AI服务非这个硬件不可”。硬件只是服务的载体，服务不成立，硬件再酷也是电子垃圾。
而EMIB-T则在硅桥中引入TSV通孔结构，使得信号可垂直穿越桥接芯片本体，实现更高密度、更短路径的垂直互连。
“中国的脱贫成就堪称奇迹。”今年2月，美国希尔邮报网站发文，在反思美国“斩杀线”现象的同时，指出中国的脱贫经验是已被证实能大规模改善民生的方法，美国应从中国的成功中学习。
