brainwane, 
@bernat Hi! It would be great if you added a redirect on your blog so links to your 2020 pip resolver work posts didn't 404. But I've created
https://github.com/pypa/pip/pull/12624
so that links in the pip docs at https://pip.pypa.io/en/latest/ux-research-design/research-results/#read-more will work again.
