Dogs act like toddlers when you need help - but cats just watch. Scientists compared 3 groups: pet dogs, cats, and human toddlers in an experiment where a human parent hides and pretends to look for an object. 75% of dogs and children helped. Cats only helped if it was in their personal interest.
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.。搜狗输入法2026对此有专业解读
