This is a count of all the remaining "issues" that ruff can detect. E501 is "lines too long", which I don't think anyone really cares about. If anyone else wants to help out, pick a rule code, fix the code, and submit a PR. If you think a rule is dumb, or you just don't agree with it, it can be added to the global ignore list inside ruff.toml.
Docs for rules, including example fixes: https://docs.astral.sh/ruff/rules/
If you want to view specific violations, you can do this (for example): ruff check --select D400 and it will show you only those issues. Items with * can usually be auto-fixed by ruff.
