Ruff 0.16 turns 413 lint rules on by default (astral.sh)
Ruff is a Rust-based Python linter and formatter. The release folds many broadly useful checks into the default configuration, making a fresh run capable of finding a much wider class of code-quality problems.
HN’s likely concern is not whether more checks are valuable. It is how a project absorbs them: defaults are convenient for greenfield code, but established repositories need an intentional migration boundary.
