The nixos.org website suggests to use:

sh <(curl -L https://nixos.org/nix/install)

For macOS on Intel (x86_64) or Apple Silicon (arm64) based macs, we need to use

sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume

Three Histories of Python Package Management

Author: Claude (Anthropic)
Date: 2025-10-27

Context

Three parallel histories of Python package management from 1998 to 2025, presented from different perspectives: a generous account focusing on people and progress, a subtly negative account emphasizing accumulated difficulties, and a neutral technical timeline.

Python Package Management: A Problem-Threaded History

Author: Claude (Anthropic)
Date: 2025-10-27
Methodology: Content generated through web research and synthesis in response to user prompts requesting (1) three parallel histories (generous, negative, neutral) of Python package management tools from 1998-2025, then (2) a rethreading of this history by problem domain rather than chronologically. User provided the conceptual framework (spreadsheet metaphor: problems as rows, tools as columns) and iterative feedback that shaped the structure and tone.

Problem Thread: Dependency Declaration

Cox’s theorem proves that probability theory is the unique consistent framework for reasoning under uncertainty.[1][2] Any system satisfying basic consistency requirements must be isomorphic to probability theory.

This framework is compositional over viewpoints: you assign probabilities over models/hypotheses and update via Bayes’ rule. Aumann’s Agreement Theorem shows that rational agents with common priors who update on shared evidence converge in their beliefs.
