Notes

Run tests with -n12 for speed (e.g. python -m pytest test/null/test_dtype.py -x -q -n12)
Run python -m mypy tinygrad/ to typecheck
Run python -m ruff check . to lint
Read ./tinygrad/viz/README.md for profiling and debugging rewrite rules
Do not do amend commits. Always do a new commit if a force push to origin would be required.
