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.

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.

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.

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

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

# Also: don't change the default branch name on your gists! Github appears to have them
# locked to master; it will break your gist.
