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.
Setup is a one-time thing. You create a vault item with your secrets (the demo repo includes a setup script for this), customize the references in .env.1password, and you’re done. Every developer on the team can share the same .env.1password file in version control and resolve it against their own 1Password account.

「過去人們認為，如果你告訴AI它是一位數學教授，例如，它在回答數學問題時實際上會更準確。」桑德·舒爾霍夫（Sander Schulhoff）說。他是一位企業家和研究員，也是「提示工程」理念的推廣者。但舒爾霍夫和其他人表示，當你尋找資訊或提出只有一個正確答案的問題時，角色扮演反而會降低AI模型的準確性。
