Helpful websites

I am currently working on my website (did you know that you can link a personal website as your URL on Bluesky! How cool is that? Hopefully this leads to the popularisation of non-corporate social media) and have a list of helpful websites which I am especially fond of. I thought it would be helpful to put them here as well, though it's a little... humble, right now. Please let me know if you have any open-source/community owned/ generally ethical contributions!
