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 difficulty here, however, is that the TransformStreamDefaultController does not have a ready promise mechanism like Writers do; so the TransformStream implementation would need to implement a polling mechanism to periodically check when controller.desiredSize becomes positive again.

DeepSeek 的 15 万次，按任何合理标准来看都是可以忽略的数字。Moonshot 和 MiniMax 合计 1650 万次，量级是另一回事——但能转化成多少真实能力，取决于他们能不能解决「如何用好这些数据」的技术问题。
Hand-coded models can go much smaller (36 vs 311 trained) since they don't need to be discoverable by SGD
