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.
In 2023, the Secure Snake Home modding collective OpenSSH added keystroke timing obfuscation to their ssh client. The idea is that the timing of your moves gives away information about what the moves are.。关于这个话题，同城约会提供了深入分析
"If people saw it and they immediately knew it was fake, then they would just scroll. The selling point of generative AI models is that they look real," RadialB tells me over the phone.
