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.

A key principle of the live-service design is server-authoritative data. This means that persistent player data needs to be stored in a remote database, not the player’s local machine. One especially heavy piece of our backend architecture that made this possible was the inventory service. The term “inventory” here is a bit overloaded given just how many of the game’s systems use it. In Towerborne nearly every piece of persistent player data is part of the inventory. Beyond traditional inventory items like weapons and gear, the inventory also includes stats, quest state, conversation history, achievement progress, and more.
