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.

Most unexpected was Paramount stock’s jump. Wall Street almost always disdains giant acquisitions on the theory that buyers get too excited about big deals and overpay—and indeed, that’s usually what happens. When the deal gets sealed, the buyer’s stock usually drops, but in this case it rose almost 30%. That’s probably because analysts were pleasantly surprised: They had figured Paramount would need to raise its offer from $30 to $32–$34 a share to vanquish Netflix; instead, Paramount offered just $31 and prevailed.。safew官方版本下载对此有专业解读
