Artemis 2 works toward April launchThe revised campaign comes as engineers work through immediate issues on Artemis II, the first crewed flight of the program. After a successful "wet dress rehearsal" — a full countdown test that loads the rocket with super‑cold fuel — teams discovered that helium was not flowing correctly to the engines in the rocket's upper stage.

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.。爱思助手下载最新版本对此有专业解读
